FOREWORD 0.1 This standard was adopted by the India0 Standards’ Institution on 30 December 1981, after the draft finalixed by the Glassware Sectional Committee had been approved by the Chemical Division Council. 0.2 This standard was first published in 1961, under the title Glossary of terms relating to glass industry’. However, the Committee responsible for the preparation of the standard decided to revise it taking into consideration that a number of new terms have come to be used in the glass industry and needed incorporation in the glossary to make it comprehensive. In the preparation of this standard considerable assistance has been derived’from the following publications: C 162-71 Standard definitions of terms relatiog to glass and glass products.

  • Glass and Glass-Ceramics
    Chapter 3 Sintering and Microstructure of Ceramics 3.1. Sintering and microstructure of ceramics We saw in Chapter 1 that sintering is at the heart of ceramic processes. However, as sintering takes place only in the last of the three main stages of the process (powders o forming o heat treatments), one might be surprised to see that the place devoted to it in written works is much greater than that devoted to powder preparation and forming stages. This is perhaps because sintering involves scientific considerations more directly, whereas the other two stages often stress more technical observations M in the best possible meaning of the term, but with manufacturing secrets and industrial property aspects that are not compatible with the dissemination of knowledge. However, there is more: being the last of the three stages M even though it may be followed by various finishing treatments (rectification, decoration, deposit of surfacing coatings, etc.) M sintering often reveals defects caused during the preceding stages, which are generally optimized with respect to sintering, which perfects them M for example, the granularity of the powders directly impacts on the densification and grain growth, so therefore the success of the powder treatment is validated by the performances of the sintered part. Sintering allows the consolidation M the non-cohesive granular medium becomes a cohesive material M whilst organizing the microstructure (size and shape of the grains, rate and nature of the porosity, etc.). However, the microstructure determines to a large extent the performances of the material: all the more reason why sintering Chapter written by Philippe BOCH and Anne LERICHE.

  • Approval of Pcrb Filing No. 311 Temporary Staffing Loss Cost Filing – Effective April 1, 2021
    August 13, 2020 PCRB CIRCULAR NO. 1744 To All Members of the PCRB: Re: APPROVAL OF PCRB FILING NO. 311 TEMPORARY STAFFING LOSS COST FILING – EFFECTIVE APRIL 1, 2021 The Pennsylvania Insurance Commissioner has approved PCRB Filing No. 311, which implements a revised methodology to calculate workers compensation loss costs and other rating values for all temporary staffing risks in Pennsylvania for policies effective 12:01 a.m., April 1, 2021 or later. The effective date of this revision aligns with the proposed effective date of the PCRB’s normal annual comprehensive loss cost revision filing, which will be filed with the Commissioner at a later date. This coordination will consolidate necessary changes that our members and other constituents must make to policies, forms and systems. Temporary staffing class codes are fully defined in the Pennsylvania Basic Manual (Manual); however they are essentially temporary staffing contractors that hire employees and assign those employees to an unrelated business for temporary work assignments varying in duration. Temporary staffing risks are not to be confused with Professional Employer Organizations (PEOs), which are defined under Rule XVIII in the Manual. The approved filing eliminates the current 37 temporary staffing class codes and creates 296 new temporary staffing class codes with each direct employment class mapping to one and only one temporary staffing class. Classifications are listed numerically in Section 2 (Classifications) of the Manual. The numeric assignment for a temporary staffing classification is a one-to-one match with a direct employment classification. Temporary staffing classifications are identified by a four-digit number that is 2,000 greater than the associated direct employment classification.

It is certainly one of the greatest process inventions of the twentieth century. The float process is one of the most widely used methods for flat glass manufacturing as it ensures security, high quality and Keywords: productivity. From a historical point this innovation was the beginning of a revolutionary change in the Glass mass production of flat glass for the building and automotive sectors. More specifically this innovation Flat eliminates the traditional operations of rolling, grinding and polishing the glass surface while creating a Float high quality and inexpensive flat glass product. The first patent was applied for on December 10th, 1953 Patent History by Pilkington and Bickerstaff. This paper presents a brief discussion from the 1960s in a historical Technology perspective about this amazing discovery and the main patents related to it.

  • A NEW TECHNIQUE in GLASS ART JOANNE MITCHELL a Thesis Su
    PRECISION AIR ENTRAPMENT THROUGH APPLIED DIGITAL AND KILN TECHNOLOGIES: A NEW TECHNIQUE IN GLASS ART JOANNE MITCHELL A thesis submitted in partial fulfilment of the requirements of the University of Sunderland for the degree of Doctor of Philosophy August 2015 Precision Air Entrapment through Applied Digital and Kiln Technologies: A New Technique in Glass Art Joanne Mitchell PhD 2015 1 Precision Air Entrapment through Applied Digital and Kiln Technologies: A New Technique in Glass Art Joanne Mitchell 2015 Abstract The motivation for the research was to expand on the creative possibilities of air bubbles in glass, through the application of digital and kiln technologies to formulate and control complex air entrapment, for new configurations in glass art. In comparison to glassblowing, air entrapment in kiln forming glass practice is under-developed and undocumented. This investigation has devised new, replicable techniques to position and manipulate air in kiln-formed glass, termed collectively as Kiln-controlled Precision Air Entrapment. As a result of the inquiry, complex assemblages of text and figurative imagery have been produced that allow the articulation of expressive ideas using air voids, which were not previously possible. The research establishes several new innovations for air-entrapment in glass, as well as forming a technical hypotheses and a practice-based methodology. The research focuses primarily on float glass and the application of CNC abrasive waterjet cutting technology; incorporating computer aided design and fabrication alongside more conventional glass-forming methods. The 3-axis CNC abrasive waterjet cutting process offers accuracy of cut and complexity of form and scale, across a flat plane of sheet glass.

For this privilege I thank the Director, NBT with all my heart. Heartfelt thanks are also due to Mrs. Kanchan Wanchoo Sharma then at the Editorial Department of NBT. Her very positive feedback to my idea gave me the encouragement to go forward with the manuscript. My current Editor Ms. Surekha Sachdeva who took over from Kanchan has been most meticulous in editing and deserves my thanks for all her efforts.
