Title: Fluid conveying pipe connector

Filed: 1974-12-10
Abstract: 1495395 Pipe connector A J M KAGAN 10 Dec 1974 [21 Dec 1973] 53440/74 Heading F2G A pipe connector of the type allowing ready coupling between an outlet duct and pressurized fluid source, is characterized in that a first member connectible to the source is provided with an auxiliary together with a main valve, whereby, when a second connecting member is brought into connecting relationship with the source member, the auxiliary valve opens initially to reduce the pressure thrust on the main valve and so facilitate the subsequent opening-by further contact of the second member, of the main valve. As shown, a valve stem 22 carries a seal 24 closable against a seating 23 formed in a concentric member 13 which carries a second seal 16 closable against a seating 17 to form a main valve. In operation a second connecting member 20 having a central portion 39 and outer annular portion 40 is thrust axially into contact with the first member, contact initially taking place between the central portion 39 of the second member and the end 22a of the valve stem to open the auxiliary valve and permit initial restricted fluid flow. This initial flow is effective in reducing the pressure difference across the main valve and so facilitates its opening upon further axial movement of the second member to bring outer annular portion 40 in contact with main valve body 13. Locking between the connecting members is effected as shown with balls 34 engaging annular recess 36 in the second member; ring 33 being movable axially against spring 35 to permit radial movement of the balls and release of the second member.

Title: Improvements in or relating to shock absorbers
IPC: B60G17/08
Filed: 1966-12-02
Abstract: 1,128,249. Hydraulic shock-absorbers. AUGUST BILSTEIN K.G. 2 Dec., 1966 [3 Dec., 1965], No. 54148/66. Heading F2S. A steplessly adjustable shock-absorber, especially for vehicles, comprises a piston 4 having two sets of ports 4<SP>1</SP> controlled by sets of spring plates 3, 5 and a hollow piston-rod 1 through which extends a tension rod 11 having its upper end connected by nuts 15, 16 to a diaphragm and support ring 13, 14 and its lower end extending through a support piston 8 which is secured thereon by a nut 10 the rim 8<SP>1</SP> of the piston 8 bearing against the rim of the largest plate of the spring set 5 with a force which depends upon the tension of the rod 11. The diaphragm 13, clamped between two housing parts 18, 20 carried by the upper end of the rod 1, divides a space in the housing 18, 20 into an upper chamber 17 which is connected to atmosphere through a port 19 and a lower chamber 22 which is connected by a bore 23 to a duct 24 leading, e.g. to an air spring bellows on the vehicle. An increase in the pressure in the chamber 22 causes the support piston 8 to increase its pressure on the corresponding plate of the spring set 5 so that the rebound stroke damping is increased. In a modification, Fig. 2, not shown, pressure control fluid is fed through a bore (42) and a port (41) in the rod (26) and through a groove (40) and bore (39) in the flange  (32) of a support disc (31) which is sealed to the rod (26) by means of gaskets (44, 45), the support disc (31) guiding a domed support piston (35) which has its rim (37) in engagement with the outer edge of a spring unit (33) secured to the rod (26) by a nut (34). An annular projection (36) on the upper face of the support piston (35) bears against the lower face of a valve spring unit (30) which controls bores (29<SP>1</SP>) through the piston (29) during extension of the unit. A fluid-tight chamber (38) in the support piston (35) is ensured by seals (43, 43<SP>1</SP>) the pressure of fluid supplied through the bore (42) in the piston-rod (26) controlling the stiffness of the valve unit (30) and thus the damping factor of the unit during its expansion strokes. The shock absorber valves could consist of valve plates loaded with coil springs. A support piston could also be mounted on the piston-rod side of the working piston so that the damping factor of the shock-absorber is adjustable on the compression stroke. If the two valve sets on opposite sides of the working piston are to work independently of each other they should be supplied through separate flow passages in the piston-rod. A pressure-equalizing opening (48) is formed in the rim 37 of the piston (35). A port 9 is also formed for the same purpose in the piston 8 as shown.

Abstract: 1,128,339. Morpholone derivatives. FARB. WERKE HOECHST A.G. 24 Dec., 1965 [28 Dec., 1964], No. 64795/65. Addition to 1,063,364. Heading C2C. [Also in Division B1] The invention comprises a method of preparing compounds of the formula in which R 1  denotes an aliphatic or aryl radical of 6-24 carbon atoms or an alkaryl radical of up to 24 carbon atoms and R 2 , R 3  and R 4  each denotes a hydrogen atom or a methyl group, at least one denoting a methyl group. The compounds are made by reacting chloracetic acid with an alkanolamine containing 3 or 4 carbon atoms and having the hydroxy and amino groups linked to adjacent carbon atoms, this reaction being effected at about pH 9-12, and condensing the product with a carboxylic halide corresponding to R 1  in the formula above. The reaction mixture is then acidified to recover the desired product. An example is given in which chloracetic acid is reacted with isopropanolamine and the product is condensed with oleic acid chloride and then acidified to yield N-oleyl-6-methylmorpholone-2. Other suitable alkanolamines and carboxylic halides are specified. The morpholone derivatives decompose when heated with alkalies to yield salts of hydroxycarboxylic acids of the formula HO(R 4 )CH-C(R 2 )(R 3 )-N(COR 1 )-CH 2 -COOMe, in which Me denotes an alkali or alkaline-earth metal ion. The corresponding free acids are unstable and are reconverted into the morpholone derivatives by ring-closure. The morpholone derivatives are useful as water-in-oil emulsifiers and the salts of the hydroxycarboxylic acids are useful as oil-in-water emulsifiers, and the decomposition of the morpholone derivatives can thus be used to bring about any desired intermediate stage of emulsification.
