POCKET CRYPTOGRAPHER TYPE CD-57
The pocke t machine CD-57 has been spe cially designed for appli cations requiring easy portability of a cipher unit, but not req uiring any printed proof.
The CD-57 is equipped with 6 keywheels with different numbers
of divisions for ciphering (and deciphe ring) . The keywheels can be selected from a choice of totally twelve . Depending on the 8 9 sele ction cipher se rie s of 7 x 10 to 6 x 10 characters can be obtained which, with the judicious use of the stepping mechanism
(see further description) will provide a very high cipher .
The following divisions of keywheels are obtainable:
25, 26, 29, 31, 34, 37, 38, 41, .42, 43, 46, and 47.
Each keywheel includes the same number of pins as divisions.
The pins can e ither be set to active or inactive positions. As a
general rule , it is recommended to place about 50 � of the pins in active positions. The step�ing mechanism acting on the pin
(key) whe els can translate the influence of the active pins ranging
from 0 to· 16 steps for each p inwheel. The maximum number of
steps, however, is limited to 40.
For instance the following setting can be arranged:

" " No. 3 4 steps
" No. 4 " 8 steps
II No. 5 " 1 0 steps
II No. 6 II 1 5 steps
When all wheels present active pin s at the same time, 40 steps
wil l be obtained . When all are inactiv e the res ult is 0 step.
The 64 pos sible combinations will produce all poss ible numbers
from 0 to 40, some of which in two or three differen t combinations.
The result of max imum 40 steps is, fro m the cryptological point
of view, a very high value.
The ciphering procedure (enciphering and deciphering) is done by
seeking the letter to be ciphered on a stationary alphabet ring
and noting the corresponding letter on a moveable alphabet dis c
ins ide the ring. For each operation the ste pp ing mechanis m acts
on that alphabet disc and turns it to one of its 26 possible
pos itions r e l a t ive to the alphabet ring.
The machine is operated as follows:
1. Primarily the machines to correspond wi th each other must be so arranged that their keying mechanisms become ide ntical (inner setting). The arrangement include s the pins in the pin wheels,
the sequence used to put the correct pinwheels into the machine,
the number of steps for the stepping mechanis m and the alphabet used.
2. For each me ss age to be ciphered the six pinwheels must be
set in an id en tical starting position (which must differ for
every mess age ) , and the alphabe t ring in one of the pos sible
26 pos itions relative to the alphabet disc ( external setting ) . I

The machine is held in the operator's left hand.
First the operating lever must be released from its rest position,
as it is locked when the machine is not in use. To do so the
lever is pushed inward with the thumb and then released. After
every manipulation the letter to be ciphered (primary letter)
is fi rst seeked on the outer alphabet ring and the corresponding
(secondary) letter, appearing on the inner disc opposite the
primary one, is written down by hand or by a typewriter. As the
two alphabet discs are inverse, the same procedure is done for'
both enciphering and deciphering. (If arbitrary alphabets are
used, the enciphering is done by mean s of the alphabet ring and
the deciphering by alphabet disc,)
F6r checking of operations a counter is provided that is set to
zero (0000) before start of operation.
Note: Users of mechanical cipher machines of the type C-4, C-52
and Converter M-209 will be interested in the fact that
the aforementioned machines can cooperate with the CD-57
if layed out accordingly.

placed upside down in the foreground. It can be s een
that the pinwheels consist of two main parts: A rin g ,
carrying the pins and a center ( marked with the number
of pins, carried by the wheel in question) which acts
as a bearing for the pin disc and in which the gear in g
for the advancement of the dis c is mounted.
The central bea ring (which is hollow) is now clearly seen. A part
of it is cut off, and inside the bear i ng (journal) a modified
Maltese cross with four driving vanes is located. When the operating I

THE KEYBOARD UNIT B-62t (B-62)
The keyboard unit B-621 is a setting and driving assembly onto which a cipher machine of the series C-5 2 can be mounted with very few manipulations. Thus the operating unit type BC-621 is built up. This combined apparatus can be operated exactly as the previous model BC-5 2, i.e. the text can be printec by tapping the keys of the keyboard. The remaining operations are automated.
A high operating speed and great convenience in use is provided.
Moreover, the B-621 provides the possibility of automatic coop eration with teleprinter services ( Telex ) when connecting the Tape Translator PEB-61. With this auxiliary equipment the secret text is punched on perforated tape for automatic transmiss ion whereby the perforated tape can be deciphered automatically. This avoids the tedious tapping of secret communications and provides at the same time a far higher security Df transmission as well as a higher operating speed. ( For details on the PEB-61 unit see leaflet No. 3134 .)
If no automatic operation is required, the keyboard unit type B-62 can be employed which is a successor to the unit B-5 2 with improved features .
Both the B-62 and the B-621 include a number of improvements agains t the B-5 2 providing a higher degree of reliability. Therefore, iess servicing and overhauling is required. Further more, the new models are equipped with a "letter check" key.

By using this equipment, the ciphered messages can be produced on punched tape and can be deciphered automati cally at the receiving side. The PEB-61 contains a motor-driven perforator, a tape reader and auxiliary components. The PEB-61 is electri cally connected· to the B-621 keyboard (fig.1 ) by means of a cable and multipole connectors, The operating current is supplied by the B-621. 2. features 2.1 Enciphering ( fig. 2) The plain text ( primary ) can be: 2.1.1 typed on the keyboard 2.1.2 inserted as a perforated tape into the PEB-61.

Operation 3.1 For paint to point co nnect ions the perf'orated text can be u sed in endless mode without the need of grou pin g the letters, provided that bath s tations are equipped with PEE-units and teleprinters including automatic tape transmitters and reperfaratars. Proceed as fallows: 3.1.1 Transmission The text typed on the keyboard is rendered in clear mode to the perforated tape, according to the CCITT No.2 code. The PEB-61 will be switched io "Prim.". The address and other information will be punched onto the tape. I 3134-e -3- After the C-52 has been set to key position and the perforated tape fed some idle steps, the PEB-61 is switched to "Sec.". The message is ciphered now. It will appear printed on the paper strip of the C-52 and punched by the PEB-61. The perforated tape can be delivered to the tele printer operator. 3.1.2 Reception The received text is punched onto a perforated tape. This will be fed to the PEB-61 and on the primary side of the C-52 beyond the B-621 the punched information will be printed in plain. Thus the operator will be able to read the address etc. After having set the C-52 to key, the perforated tape should be advanced until the first letter has been read by the sensing brushes in the tape reader. The unit is started again. On the secondary side of the C-52 the now deciphered plain text will appear automatically. 3.2 For systems that do not allow a direct connection, the perforat text must be supplied in groups comprising 5 letters each, as required by the international Telegraph Regulation, art� 20. For such applications the programming unit built into the PEE-61/a is used ( Fig. 4 ) It produces a perforated tape with the letter perforation grouped, intermixed with "space", "carriage return" and "line feed" signals after 10 groups each so as to allow a page teleprinter ( which may be somewhere in the transmission path ) to render the text well arranged onto a paper sheet (Fig.5). When deciphering the PEB-61/a suppresses automatically the signals "space", carriage return" and "line feed" which were fed on the sending side� I 3134-e -4- It is possible to have a new tape punched by the PEB-61/a which,. like the original text, includes spaces in the deciph deciphered (plain) text and which is arranged in lines of 68 characters each. That tape can be fed into a locally connec ted page printer using it instead of an electric typewriter in order to render the deciphered message onto paper sheets. This mode is more convenient than glueing the tape or retyping the deciphered message. Also any desired number of copies can eas ily be obtained when using a page printer (Fig.6) Encl.: Fig. 134 •••6 ZGD OST/iz - C\J (.)
