Filed: 1967-03-23
Abstract: 1,160,930. Valves. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. 23 March, 1967 [25 March, 1966], No. 13625/67. Heading F2V. A three way flow regulator which divides a pressurized inlet flow D into a flow of constant magnitude, directed into an outlet 10 having a servo-motor of a tractor steering gear connected to it, and into a residual flow, directed into a second outlet 9 having a power lift device connected to it, has a tubular hollow control member 3 disposed within a bore 2 into which the inlet and two outlets open. The control member is biased into its uppermost position by a spring 5, has formed within its interior a valve seat 15 engageable by a spring loaded valve disc 16, carries a diaphragm 14 and is in open communication with the outlet 10 by bores 13 formed in its wall. Fluid flow to the first outlet 10 is regulated by the relative disposition of edges 10d and 12a. An increase in the inlet pressure resulting from an increase in the output from a pump driven by the tractor engine, results in a downward movement of the control member and hence delivery of fluid to both outlets. Upon the pressure within outlet 9 being reduced, as by locking of the lifting device, the control member rapidly moves to the position shown so preventing a pressure loss in outlet 10, this movement being uninhibited as upon commencement of this movement, member 16 becomes unseated and so prevents the formation of a vacuum in chamber 6.

Patent GB-461236-A (GB)
Title: The manufacture of new artificial fibres, films and the like
IPC: C08L75/02
Filed: 1935-05-09
Abstract: One or more monoaminocarboxylic acids having at least one hydrogen atom attached to the amino nitrogen, amide forming derivatives thereof or low molecular weight polyamides derived therefrom, or derivatives thereof, or mixtures thereof, are subjected to heat treatment in the presence of an inert solvent for a time sufficient to form a product which is spun into continuous filaments or formed into sheets or films and subsequently subjected to moderate stress. The amino- and carboxylic acid radicals are on the carbon atoms most remote from one another.  The reaction is preferably conducted in an inert atmosphere such as nitrogen or in the presence of an antioxidant such as syringic acid.  Suitable solvents include monohydric phenols such as cresol, phenol, xylenol, thymol and p-butylphenol or cyclohexanol, acetophenone, diethyleneglycol and benzyl alcohol.  Alkaline oxides or carbonates or halides of polyvalent metals may be included as catalysts.  The reaction mass may also include dicarboxylic acids or their esters and diamines as disclosed in Specification 461,237.  Suitable aminoacids include those of the general formula NH2(CH2)N COOH, where N is 5, 6, 7, 8, 9, 10, 12, 16 and 21, 2-methyl-5-aminopentane carboxylic acid and p-o -aminoethylbenzoic acid.  In the manufacture of fibres, the polyamide may be dissolved, with or without the addition of a cellulose derivative such as nitrocellulose cellulose acetate and ethyl cellulose, in a suitable solvent, extruded through orifices into a coagulating chamber or a heated chamber, and wound on a revolving drum or spindle.  Alternatively, fibres may be obtained by touching the surface of the molten polymer with a rod and drawing away the fibre so obtained.  The fibres are then cold drawn.  The fibres are capable of absorbing permanently from a weakly acid medium those dyes ordinarily used for silk and wool.  Sheets, bands, films or ribbons may also be prepared.  In examples: (1) a solution of 9-aminononanoic acid in xylenol is heated in an atmosphere of nitrogen to yield a polyamide which is extruded in a molten condition through a heated orifice to yield a fibre which is then cold drawn; (2) a solution of 7-aminoheptanoic acid in m-cresol is heated in an atmosphere of nitrogen and worked up as in example (1); (3) the ethyl ester of 6-aminocaproic acid is heated in a closed vessel and then worked up as in example (1).

Abstract: 1,055,716. Hydraulic brakes; hydraulic dampers. W. HARTUNG. April 2, 1964 [April 3, 1963], No. 13673/64. Headings F2F and F2S. In an hydraulic braking mechanism for a motor vehicle, the two hydraulically separate outputs from a single master cylinder or two master cylinders 2, 3 are connected to the wheel brake cylinders 8, 9 through a device 6 which disconnects one of the master cylinders from the wheel brake cylinders when the brake fluid reaches a predetermined pressure. In one embodiment of device 6 the output from master cylinder 3 communicates with the wheel brake cylinders via pressure chamber 111 below a piston 118, loaded by a spring 121 and a spring-loaded valve 114 so that when the pressure in chamber 111 reaches the predeter mined value the piston 118 will rise, compressing spring 121 and permitting the valve 114 to close. The movement of the piston 118 is delayed by means of an hydraulic damper comprising a piston 101 and a restriction 126 therein until the piston 101 has moved sufficient to uncover passage 124 when the movement of the combined pistons 118, 101 is unrestricted. In another embodiment of device 6 the pressure in chamber 111 is communicated to a chamber below the piston 118 via a restricted passage. The two sets of wheel brake cylinders 8, 9 may each be connected to the device 6 through an hydraulically separating pistoncylinder device.
