Abstract: 1,125,841. A vehicle brake-pressure regulating device. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK K.G.]. 25 March, 1966 [17 Sept., 1965], No. 13309/66. Heading F2F. A vehicle load-responsive brake pressure regulating device comprises a brake pressure regulating valve 2 having ports 19 and 18 connected to a master cylinder and wheel brake cylinders respectively, a cylindrical casing 1, which is attached by lugs 3 and 4 to the vehicle frame and which receives said valve and a compression spring 10, said spring acting on the control or actuating member 17 of the regulating valve, and a two-armed lever pivotablymounted in a bearing lug 5 on the casing and having one arm 6 acting on the compression spring through a strut member 9 and the other arm 7 connected by a link 8 to the vehicle axle 11 said arms being relatively angularly adjustable. Movement of the vehicle axis relative to the vehicle frame is transmitted by the linkage 6, 7 and 8 to unload or load the compression spring and hence suitably control movement of the valve actuating member 17. The arms 6 and 7 of the two armed lever are each formed by pairs of members, Fig. 2 (not shown), the ends of each pair being coupled by a nut and bolt 12 with interposed toothed washers 21 and a clamping sleeve 15 so that the angular position of the arms 6 and 7 may be suitably adjusted to the axle displacement expected. In addition, the link 8 may be replaced by others of different length. The valve comprises a differential piston 24 which moves to the right at a predetermined pressure when the loading of spring 10 is overcome so that a valve obturator 30 seats on seat 27 of a tubular element 32 carried by the piston to shut off flow through the piston, pressure to the brakes being then dependent on the differential areas of the piston.

Abstract: The invention comprises silicone lubricants of the formula <FORM:0773916/IV(a)/1> where n is at least 1, X is chlorine, bromine, fluorine or trifluoromethyl, and m is 1 to 4.  They may be prepared by equilibrating a cyclic dimethyl siloxane with a disiloxane of the formula <FORM:0773916/IV(a)/2> in the presence of sulphuric acid; or by cohydrolysing a mixture of a dimethyl silane, having two hydrolysable groups, and a chainterminating silane of the formula <FORM:0773916/IV(a)/3> where Y is a hydrolysable group.  In the examples: (1) dimethyl dichlorosilane (32 mols.) is cohydrolysed with x,x-dichlorophenyl dimethyl chlorosilane (16 mols.) to give a fluid having the above formula, where n is 4 and Xm is Cl2.  Other products are similarly prepared using different proportions of the same reactants.  (2) Meta - trifluoromethylphenyl dimethyl chlorosilane is cohydrolysed with dimethyldichlorosilane as in (1) to give a siloxane of the above formula where n is 4 and Xm is m-CF3.  Example 1 is also repeated using polychlorophenyl dimethyl chlorosilane having an average of 3.5 chlorine atoms per phenyl group.  (3) 4 - Chloro - 3 - (trifluoromethyl) phenyldimethyl ethoxy silane is prepared from dimethyl diethoxysilane and 4-chloro-3-(trifluoromethyl) phenyl magnesium bromide, and is hydrolysed to the disiloxane.  This is equilibrated with hexamethylcyclotrisiloxane to give a siloxane of the above formula, where n is 3 and the phenyl groups are substituted in the 3-position by CF3 and in the 4-position by Cl.  (4) Fluid siloxanes are prepared from hexamethylcyclotrisiloxane and (a) bis-p-chloro-, (b) bis-p-bromo-, and (c) bis-p-fluoro-phenyltetramethyldisiloxanes. The freezing points of all these polysiloxanes are below - 54 DEG  C. and they are not adversely affected at temperatures of the order of 204 DEG  C.  The lubricants may comprise mixtures of these polysiloxanes, and other siloxanes, e.g. dimethyl polysiloxanes, and solid lubricants, such as molybdenum disulphide, may be added.  Reference has been directed by the Comptroller to Specifications 667,179, 688,166 and 706,703.ALSO:A lubricant, which is effective within a temperature range of at least -54 DEG  to 204 DEG C, comprises one or more fluid polysiloxanes of the formula <FORM:0773916/III/1> where n is at least 1, and preferably from 3 to 6, X is chlorine, bromine, fluorine or trifluoromethyl, and m is 1 to 4.

Filed: 1946-05-07
Abstract: 613,472. Making heat-exchangers. FORD MOTOR CO., Ltd., and LEEK, J. W. May 7, 1946, No. 13818. [Class 83 (ii)] A machine for making radiators of the kind having a plurality of metal tubes passing through a number of parallel metal fins comprises means for feeding fins and separator members alternately on to a movable platform to form a stack of fins disposed in spaced relationship. A strip of sheet metal is fed as by the mechanism described in Specification 613,471 to a machine in which it is perforated and cut to form individual fins which are then fed successively on to a conveyer belt 6, Fig. 2, by which they are carried on to a stacking platform 7. Separators 2 are placed on an inclined feed tray 10, Fig. 7, and are urged towards the platform 7 by a slowly moving conveyer belt 11. As each fin moves beneath rollers 16, 17, above the belt 6, the slight movement imparted to the rollers is utilised to operate a valve supplying hydraulic fluid to a cylinder 22. This operates a shaft 24, Fig. 5, which in turn operates reciprocating members 12, 13 forming an escapement permitting the separators to pass one at a time off the edge of the tray and fall on to a fin on the platform 7. Thus one separator is released for every fin fed by the belt 6 and a stack of fins separated by the members 2 is built up. The cylinder 22 also actuates a pawl 31 engaging a rack 30 by which the platform is lowered step by step. The platform is counter-balanced by chains or ropes 35 passing over a pair of pulleys 36 to a set of compensating weights 37, 38, 39, 40. When a stack of fins and separators has been completed a valve 43 is operated to supply pressure fluid to a cylinder 42 to operate a pusher 41 by which the stack is moved off the platform 7. The rack 30 is then turned through 90 degrees to permit the platform to return to its upper position.
