Title: Improvements in locks especially for house-doors
IPC: E05B37/16
Filed: 1935-08-09
Abstract: 452,610. Combination locks. LEBEAU, L., 293, Rue Croix-Jurlet, Herstal, Belgium. Aug. 9, 1935, No. 22483. Convention date, Aug. 9, 1934. [Class 44] A combination lock for house doors &c. comprises a bolt 2 operated independently by outside and inside handles 3, 3<a>, through tumblers 5<a> and 7<c>, 7d engaging lugs 2<a> and 2<c>, 2d respectively on the bolt. The tumbler 5<a> has an arm 5<d> adapted to be blocked by a slide 9, which is retracted to release the tumbler when a number of controlling elements 18 are moved into predetermined positions to allow a slide 11 connected to the slide 9 to be moved by a spring 12. The elements 18 are of T-cross -section, Fig. 4. the legs of which slide in slots 17<a> in a plate 17 and block pins 13 on the slide 11 until the elements are moved into such a position that slots 18<a> therein are aligned with the pins. Another pin 14 on the slide 11 has to be released by moving a plate 20 in slot 17b until a projection on it is clear of the pin. The elements 18 are moved by push buttons 21 which force spring fingers 22 into engagement with teeth 18b, causing the elements to move one tooth down for each operation of the buttons. The slide 9 is reset in blocking position by raising the plate 20 by means of a finger piece until a cam surface 20<a> thereon moves the pin 14 and slide 11 laterally, and the elements 18 are scattered by raising the plate 20 until a cross-bar 20<b> engages the ends &c. of bolts 19<a> mounted on the elements and carrying a variable number of removable discs 19.

In a tubular heat exchanger comprising a plurality of tubes 12 in a shell 18, a primary baffle 15 extends the length of the shell and divides it into two parts which may communicate with each other only through a narrow longitudinal aperture 32 formed by spacing the edge 31 of the baffle away from the shell wall, supplementary baffles 16 and 17 mounted on some of the tubes being ar. ranged to prevent flow of fluid directly around the inner circumference of the shell. As shown, coolant flows from header 22 through tubes 12 into an opposite header (not shown) and the fluid to be cooled e.g. lubricating oil for high horsepower heat-engines flows into the shell via inlet 19, over tubes 12 in the top part of the casing, eventually flowing through the longitudinal aperture 32 into the lower part of the casing, then over the remaining tubes 12 and hence to outlet 20. The tubes 12 may be made of seamless copper and are soldered into the tube plates 13 and 14. The tube plates are forged brass and fit telescopically into the shell 18. The primary and secondary baffles are formed of spring brass and are shaped as illustrated in Figs. 7 and 8 (not shown) all the baffles having a portion e.g. 29, 36 respectively adapted to extend into contact with the wall of the shell.

The assembly has a second diaphragm 17 with a control member 16 and a guide flange 33 which co-operates with the guide surface, which is formed on an annular insert 28. The second diaphragm 17 is held down against a spring 46 in use by atmospheric air in the chamber 20 opposing a vacuum from a manifold in a third chamber 22; upon vacuum failure upward diaphragm and member movement moves a piston 44 of the valve 42 to allow full master cylinder-brake cylinder communication. During normal operation the valve 24 allows vacuum in the chamber 18 to cause the diaphragm 15 to move a piston upwardly to allow full master cylinder-brake cylinder communication; upon receipt of a skid signal, air is allowed into the chamber 18 to cause the diaphragm 15 to move downwardly to initially cause interruption of fluid flow to the brake cylinders and then causes pressure reduction by volume increase. The control members 14, 16 and the insert 28 are of metal or synthetic plastics.

Abstract: 1463499 Mounting components on circuit boards LUCAS ELECTRICAL Ltd 3 May 1974 [16 May 1973] 23267/73 Heading B3A A method of mounting an electrical component 12 on a circuit board comprises feeding the component which has leads 11 to a mounting station 13, clamping a portion of each lead 11 at the station, bending a portion of each lead, which portion is located on the opposite side of the clamped portions from the component, unclamping the leads, and effecting relative movement between the component and the circuit board so that the leads engage the board. Each of the leads is cut to length at a location spaced from each clamped portion. Apparatus for performing the method comprises a yoke 15 and a pair of movable, spaced anvils 14 for clamping the leads which are attached to bands 10 on the apparatus. Cutters 18 co-operate with shear blades 19 to cut the leads upon descent of the assembly of formers 16, drivers 17 and cutters 18. The formers 16 contact the cropped leads and bend them to the required shape while the drivers 17 urge the component 12 and leads 11 downwardly into engagement with the circuit board which is held on a movable platform. The assembly is then raised to permit the bands 10 to feed another component to the mounting station under the yoke 15. The leads are soldered in position in holes in the board.

Patent GB-780857-A (GB)
Title: Improvements in and relating to the production of polyacrylonitrile threads, filaments, fibres and the like
Inventor: BENNETT ALBERT WALTER
IPC: D01F6/18
Filed: 1954-08-12
Abstract: Polyacrylonitrile threads of improved dyeing properties are produced by extruding a polyacrylonitrile solution into a coagulating bath to form threads and treating the resultant threads in the wet, swollen state, before they are dried, with a solution of caustic soda or caustic potash.  The term "polyacrylonitrile" includes copolymers containing a predominating proportion of polyacrylonitrile.  The caustic alkali may be in solution in water or in an organic liquid which is also a solvent for the liquid with which the undried threads are swollen, e.g. aqueous ethanol.  Threads spun into aqueous or aqueous-alcoholic coagulating baths are preferably treated with 1-4 per cent aqueous or aqueous-alcoholic solutions of the caustic alkali at 20-80 DEG  C. for a period ranging from 2 minutes to several hours.  In an example, a solution consisting of 14 parts of a 94/6 mol. per cent acrylonitrile-methyl acrylate copolymer, 39 parts of sodium thiocyanate, 23.5 parts of methanol and 23.5 parts of water is spun into a coagulating bath at 20 DEG  C. consisting of 4 parts of water and 1 part of the sodium thiocyanate-methanol-water mixture used as the solvent in the spinning solution.  The resultant threads are withdrawn from the bath, washed with hot water, stretched to 7 times their original length in steam at 100 DEG  C. and then immersed in a 2 per cent aqueous solution of caustic soda at 40 DEG  C. for 2 hours.  The treated threads are then washed with water, immersed for 30 minutes in a 5 per cent aqueous hydrochloric acid solution at room temperature, to discharge a yellow discolouration of the threads resulting from the alkali treatment, washed with water and dried in air at 70 DEG  C.  In other examples threads are similarly prepared and treated using the same spinning solutions to which have been added 0.4 part and 0.6 part of a piperazine-epichlorhydrin reaction product and a butylamine epichlorhydrin reaction product respectively.  The piperazine-epichlorhydrin reaction product is prepared by allowing a mixture of 8.1 parts by weight of piperazine and 6.9 parts of epichlorhydrin to stand overnight, heating the mixture for one hour at 60 DEG  C., adding a further 13.8 parts of epichlorhydrin and continuing the heating in an open vessel until a highly viscous reaction product is obtained.  The n-butylamine-epichlorhydrin condensation product is prepared by heating a solution of 16.8 parts of n-butylamine and 8.4 parts of caustic soda in 50 parts of water to 40 DEG  C. under a reflux condenser, discontinuing heating, and adding 33.4 parts of epichlorhydrin at such a rate that the heat of reaction keeps the mixture boiling.  The upper viscous layer of condensation product is separated and washed with water.  Specification 729,472 is referred to.
