ELECTRICAL REVIEW, APRIL 28TH, 19 4-1 { • CONSUMER SAMPLING ii Electrical Review April 2 8 , 1 9 4 4 PRIDE & PREJUDICE It is with feelings of pride that we look back upon our pioneering efforts in the introduction of Fusion Weldecj boiler drums and pressure vessels, as it is yet another successful surmounting of the prejudice of ill-informed criticism . This construction was accepted by Lloyd’s Register of Shipping on the 24th May, 1935, and subsequently by all recognised engineering Insurance Companies, the Board of Trade, the Admiralty and the British Standards Institution (B.S.I 113 : 1943). This is no small testimonial to the willingness of legislative bodies to alter their Regulations permitting legitimate progress based on sound engineering principles.

E. Jolly, Esq., Borough Electrical Engineer, Bethnal Green. D.C. Bias can enable a supply authority to undertake additional loads of space heating and water heating on feeders already carrying the maximum load at peak. The effect is clearly shown in the load curve illustrated in which a feeder already carrying a peak load of approxi mately 370 amperes is now supplying an additional load of 200 amperes without exceeding its maximum capacity of 500 amperes. Space heating for a factory provided the load and D.C. Bias enabled it to be successfully supplied over an existing feeder without overloading and with central control of the peak condition by the supply a u th o rity .
