Title: Improvements in or relating to interlocking mechanism for electric switches
Inventor: REEVES FRANCIS
IPC: H01H21/06
Filed: 1960-02-10
Abstract: 918,245. Switch cases. GENERAL ELECTRIC CO. Ltd. Feb. 3, 1961 [Feb. 10, 1960], No. 4686/60. Class 38 (5). The cover 5 of a switch casing 1 is interlocked with the switch-operating shaft 2 such that the cover 5 cannot be removed when the switch is on and the switch cannot be closed when the cover is open, except for deliberate testing. A latching arm 7 is pivoted inside the casing at 8 and urged clockwise (Fig. 2) by a spring (not shown) which also tends to move the upper end of the arm away from the casing wall, as indicated by the arrow A in Fig. 1. A bracket 9 on the casing and a catch-member 14 on the cover 5 have cut-out notches shaped as shown in Fig. 1 to co-operate with the end latch 7. As shown in Figs. 1 and 2 the cover 5 is open, and the lower end of latch 7 is engaged by a step 12 of a cam 6 secured on switch shaft 2, thus preventing rotation of shaft 2 to close the switch. When the cover 5 is closed the edge 15 of the notch in catch member 14 forces the upper end of latch 7 against the sloping surface 11 of bracket 9 and the latch 7 is thus moved to the left and fully enters the notch in catch member 14. The switch can now be moved to its " on " condition as the lower end of latch 7 has risen above step 12, and the cam 6 then prevents latch 7 rotating, as shown in Fig. 5. Should it be required to test the switch with the cover open, the latch 7 may be manually pressed into this position. The cover may then be replaced without opening the switch contacts again by merely pressing in on to the top of the casing since the inclined edge 17 of the lower end of catch 14 will ride over the top of latch 7 pulling the cover 5 a short distance laterally until the catch 14 is fully engaged on latch 7.

Title: Processing of cellulosic material
IPC: D06M15/05
Filed: 1962-02-07
Abstract: The hand, tear strength and voiling properties of cellulosic materials treated with a textile resin and/or wet cross-linking reagent to impart wrinkle resistance thereto are improved by applying to the material before, diverging or other treatment to impart wrinkle resistance a polyethylene softener and at least 0.2 parts by weight per part of polyethylene, of a modifier which is a derivative of starch or cellulose comprising recurring units of the formula <FORM:0978852/D1-D2/1> in which at least one R comprises an anionic radical.  The remainder being hydrogen, lower alkyl (1-4 carbon atoms) or the corresponding hydroxy alkyl radicals, the number of anionic radicals being sufficient to constitute at least 4% up to 30% by weight of the modifier, and any of the free hydrogen atoms in the glucoside unit may be replaced by a lower alkyl radical containing 1-4 carbon atoms.  The anionic radical may be <FORM:0978852/D1-D2/2> in which X is hydrogen or an alkali metal.  The wrinkle resistant properties may be imparted to the materials by treating them with urea-formaldehyde, methylated urea-formaldehyde, acrolein urea formaldehyde, cyclic ethylene or propylene urea formaldehyde, tri- and tetra-methylol acetylene diurea, melamine-formaldehyde, methylated melamine formaldehyde, triazone, e.g. 1, 3 dimethylolmethylperhydrotriazone, epoxy, tris-(1-aziridinyl) phosphine oxide, polyglycolacetal, phenol-formaldehyde or tetramethylol acetone resins.  The materials may be treated with a bath containing 1-25% by weight of the resin imparting wrinkle resistant properties, 0.25-5% based on the weight of the resin of polyethylene, at least 0.2 parts by weight of modifier per part of polyethylene, an acid acting catalyst, e.g. the hydrochloride and nitrate salts of hydroxy alkyl amines, zinc nitrate, zinc fluoroborate, magnesium chloride, acid fluoride salts, ammonium chloride and pyridine chloride, and a wetting agent, and may then be dried at a temperature between room temperature and 140 DEG C. and cured by heating to a temperature of 140 DEG -200 DEG C.  The material may be modified or if previously treated with a textile resin additionally modified by treatment with wet cross linking agents e.g. epoxides, haloepoxides, halohydrino or divinyl sulphone, in the presence of alkalis the alkali being applied before or after the wet cross linking agent if desired.  The modifier may be applied during the alkali treatment or in the resin bath.  The treated material may be subjected to mechanical treatments with, for example, a button breaker.  Fibres, threads, yarns and woven or knitted fabrics comprising cotton, linen, jute, flax, regenerated cellulose or cellulose derivatives containing free hydroxyl groups, alone or in admixture with nylon, polyacrylic or glycol-terephthalate fibres may be treated.

Title: Improvements in or relating to processes for the separation of gaseous mixtures
IPC: F25J3/04
Filed: 1924-02-25
Abstract: 212,533. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. March 10, 1923, [Convention date]. Separating gaseous mixtures by liquefaction.- In the separation of the constituents of gaseous mixtures by liquefaction and rectification by employing expansion with production of external work and utilizing the separated gas or gases to cool a part of the gaseous mixture to liquefy it wholly or in part, this part of the mixture is compressed to a higher pressure than the other part, and the liquid so produced, and in some cases a part of the gas, is expanded by simple throttling to a pressure greater than that of the separating column, the gas so produced being expanded with production of external work, liquefied and separated. The second expansion may be combined in one process with the expansion of the other, low-pressure, portion of the gaseous mixture. In a modification, the throttling may be replaced by an independent expansion of the high pressure gas, which is then delivered to the separating column. In the apparatus shown, air compressed to about ten atmospheres passes through an interchanger B traversed in the opposite direction by the separated oxygen and nitrogen passing through tubes B<1> to the outlets U, S. The cooled compressed air is expanded in a motor D, and the expanded mixture passes through a pipe M<1> to a. coil M in the bottom of a rectifying column N. Here it is cooled by the oxygen collecting in the bottom, and after expansion through a valve O<1> is delivered to the top of the column. The oxygen is withdrawn from the column just above the liquid, in gaseous form, and delivered by a pipe T to the interchanger B. The nitrogen passes from the top of the column to a second exchanger F, and thence is delivered partly to the exchanger B and partly to an outlet Q. Air compressed to say 800 atmospheres is passed through the exchanger F and expanded through a valve G, from which the gas passes to the motor D while the liquid so formed is delivered to the pipe M<1> leading to the separator. In a modification, the valve G is suppressed, the high pressure air passing to an engine or turbine the exhaust of which is delivered to the coil M. Specification 17216/09 is referred to.
