Title: Improvements in or relating to hydraulic fluid regulating valves

Filed: 1952-05-08
Abstract: 718,310. Valves. RHEINMETALL-AKT.- GES. May 8, 1952, No. 11695/52. Class 135. [Also in Group XXXII] A regulating valve comprises a resilient plate 19 having one or more flow passages 20, a member 28 having a seating for the plate 19, and a cover member 21 permanently securec to the central region of the plate 19 to block the passages 20 when the valve i in its rest position, the seating and the member 21 co-operating with the same face of the plate 19. As shown, the valve is embodied in a hydraulic shock absorber (see Group XXXII). The respective action of the valve assembly in the piston and the base valve assembly, are identical. When the direction of flow is such as to urge the resilient plate 19 against the fixed seating 28, the plate 19 flexes and liquid is able to pass through the apertures 20, and between the plate and the periphery of the cover member 21. For flow in the other direction, the whole assembly lifts against the action of the spring 18. The spring 18 of the valve assembly in the piston, is stronger than the corresponding spring of the base-valve assembly. The tension of the spring 18 is less than the spring force exerted by the plate 19 against seating on the cover member 21. Axiallyextending ribs are formed on the periphery of the member 21.

Filed: 1955-04-25
Abstract: Esters of alkyl substituted phenol-formaldehyde resins in which the alkyl group contains from 1 to 8 carbon atoms, having a polymerizability index of from 140 to 1000 are made by esterifying at least 50 per cent of the hydroxyl groups of said resin which is free from monomeric phenol and condensation products containing two phenolic nuclei and has a viscosity within the range 5 to 35 centistokes in a 30 per cent solution by weight in dimethyl formamide, with at least one unsaturated fatty acid containing from 8 to 22 carbon atoms and having a bodied viscosity of 20 to 1000 centistokes, or a mixture thereof with a rosin acid.  The preparation of the resins is described in Specification 800,999.  Specified fatty acids include those derived from drying and semi-drying oils, e.g. from soybean, linseed, tung, perilla, sunflower, oiticica, safflower or menhaden oils.  In the examples, resins derived from p-tertiary butyl phenol and formaldehyde in the presence of hydrochloric or oxalic acid are esterified with: (1), (4) and (7) C18 acids of soybean oil; (2), (6), (9) and (11) linseed oil fatty acids; (3), (5), (8) and (12) dehydrated castor oil fatty acids; (10), (13), (14) and (16) soybean oil fatty acids; (15) fish oil fatty acids; (17), (18), (19), (20) and (21) a mixture of soybean oil fatty acids and rosin acid; and (22) white gum rosin and dehydrated castor oil.  In many of the examples, triphenyl phosphite is used as an esterification catalyst.  Films may be cast from solutions of the esters in mineral spirits containing cobalt and lead naphthenates.

The embodiment is an automatic machine Fig. 4 (not shown) where a turret 44 is supplied with a continuous strip 26 of pouring spouts 10 as in Fig. 1 (not shown) from a reel 24, separated within the machine by braking fingers 101 operated by a tined cam 53 as best seen in Fig. 9 (not shown). The turret 44 has 12 heads, facing in alternate directions to suit the alternating orientation of the spouts 10, and is powered by a motor 35 through reduction gearing 33, 31 and a belt 38. Cylindrical containers 20 are supplied to the turret 44 by a gear-driven pocketed wheel 93, and each enters a head of the turret 44 and is placed in a pocket 63 on top of a spout 10. As shown in Fig. 7, rotation of the turret 44 causes the container 20 and its pocket 63 to be pressed radially inwards against a spring 72, Fig. 11 by a cam 70. The band 14 however remains radially stationary on the convex end of a shoe-plate 74, Fig. 11, until the final radial movement inwards of the pocket 63 causes a support member 62 to engage a projection 77 and produce radially inward movement of a holding plate 76 so allowing the band 14 to spring over the uppermost part of the container rim as in Fig. 12 (not shown). The assembly 10, 20, is released from the turret 44 after rotation between angular positions 84 and 85 Fig. 7 and rolls onto a chute 23.
