Filed: 1925-07-16
Abstract: 252,654.. Lilienfeld, L. May 30, 1925, [Convention date]. Cellulose xanthates, and processes for making filaments and films from.-Esters of cellulose xanthic acids are prepared by acting on a cellulose xanthic acid or a cellulose xanthate with an ester of an inorganic acid under faintly alkaline, neutral, or acid conditions. The parent material may be crude or purified viscose, or even the product of the reaction between carbon disulphide and alkali-cellulose; the purification may consist in precipitation with a salt solution or with alcohol or by carbon dioxide, or in treatment with sulphurous acid or a bisulphite. The reaction occurs without extraneous supply of heat, but it may be initiated or accelerated by heating. The products tend to separate as jellies, except in cases where the reaction mixture is dilute when they appear as fine or coarse precipitates. The products, which are washed with alcohol, water, ether, benzene, &c., are soluble in dilute alkali lye and in many organic solvents such as an aqueous solution of pyridine, and the solutions may be worked up into films, artificial silk, and the like, plastic masses, coatings, and layers of all kinds. In examples, a crude viscose diluted with water and rendered faintly alkaline, neutral. or acid with acetic acid, is treated with diethyl or dimethyl sulphate, ethyl or methyl iodide, and ethyl bromide.

Filed: 1937-07-01
Abstract: 497,964. Making hollow glass blocks. OWENS - ILLINOIS GLASS CO. July 1, 1937, No. 18336. Convention date, July 2, 1936. [Class 56] Relates to a machine for making hollow glass blocks each of which consists of two portions united at their edges, the two portions being formed in separate moulds. According to the invention, means are provided for heating the edges only of the two portions and for pressing them together to unite them into a hollow block, the edges being coated if desired with liquid bonding-medium, as described in Specification 461,465. The blocks are made in a series of moulds 11, attached in pairs to an endless chain 10, Figs. 1 and 2, in which charges 12 of molten glass 12 are formed into half-sections 13 of the finished blocks. After the formation, the moulds become inverted and the exposed edges of the glass sections are reheated by electric heaters 33. These are carried by pairs of heating-units 30 provided with vertical stems 31 which slide through guides in a horizontal carriage 19 reciprocated by a cam 24. Another pair of units 40, mounted on stems 41 which also slide through the carriage 19, carries a liquid bonding-medium, such as molten aluminium. Another horizontal slide 45, reciprocated by a barrel cam 60, carries adjustable cams 51 which raise and lower the units 30 and 40. The slides 19 and 45 are moved in timed relation with the conveyer 10, so that the heaters 33 and the liquid aluminium are applied in turn to the edges of the glass units as they are carried along by the conveyer. After the edges of the glass sections have been coated, the moulds are swung towards one another by guide rails 73 and the sections are pressed together, as shown in Fig. 3, to form finished hollow blocks. The liquid aluminium in the units 40 may be replaced by molten lead, or other metal which does not stick to glass, in order to soften the edges of the sections sufficiently to form a glass-to-glass seal.

Title: Improvements in or relating to protective cut-out systems
IPC: H02H3/02
Filed: 1931-06-17
Abstract: 380,520. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Bergvall, R. C. ; 321, South Avenue, Wilkinsburg, Pennsylvania, U.S.A.) June 17, 1931, No. 18352/32. Convention date, June 19, 1930. Divided on 380,808. [Class 38 (v).] In order to ensure the rapid tripping of a circuit breaker in cases where the relay controlling the tripping circuit may sometimes flutter rapidly, the trip coil is shunted by an impedance of such a nature that the current builds up rapidly therein to a value sufficient to maintain an arc across the fluttering relay contacts, and the slower building-up of current in the highly-inductive trip coil is continuously maintained. As shown in the Figure the trip coil 13 of the circuit breaker 12 is shunted by non-inductive resistance 14 the trip coil circuit being completed by a contact 17 controlled by a relay 15. When the tripping circuit is closed the current rises rapidly in the non-inductive byepass circuit and more slowly in the highly-inductive trip coil. If therefore, as frequently occurs, a fluttering or chattering takes place at the contactor contacts by which they are rapidly and repeatedly separated through a small distance the current flow in the byepass circuit is sufficient to produce arcing at the contactor contacts, so maintaining a current flow in the tripping circuit in spite of the contact separation therein and allowing a continuous building-up of current in the tripping coil itself. Thus the tripping takes place on fault in a minimum time, the tripping circuit being opened automatically by back contacts 18 which are operated with the main circuit-breaker contacts. Specification 380,808 is referred to.

Abstract: 679,632. Spectroscopes. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. July 12, 1949 [July 13, 1948], No. 18395/49. Class 97 (i) In a spectrophotometer for measurement in the infra-red range a monochromator includes entrance and exit slits, and a prism for producing a spectrum scanning the exit slit, means being provided automatically to vary the entrance and/or exit slit to maintain the practical resolving power substantially constant over a substantial pair of the range of wavelengths to be studied. As shown, light enters the slit 3 and is reflected by a plane mirror 9 on to a concave spherical mirror 7 directing it to a similar mirror 8. The beam from mirror 8 is parallel and is directed to a prism 6, e.g. of rock-salt and a plane mirror 2 whence it is reflected back through the system to fall as a spectrum on the exit slit 4. The slits 3 and 4 comprise members 3a, 3b, 4a, 4b, one or both of which is moved by the linkage shown engaging a cam 1b connected. to a second cam la rotated simultaneously by a shaft 5, the cam 1a engaging a linkage to rotate the mirror 2 to cause the spectrum to scan the slit 4. In addition to maintaining the resolving power constant the cam system may be arranged so that the spectral slit ranges corresponding to the various wavelengths pass the exit slit in equal times by suitable shaping of the cam surface 1a. The apparatus is used with an electrical recorder the recording paper of which is driven by the shaft 5 and which includes means to compensate the variations in intensity of the light passing the slit 4 as the slit widths are varied.
