Title: Improvements in or relating to hydraulic dampeners
IPC: F16F9/19
Filed: 1956-08-10
Abstract: 797,477. Dashpots. MONROE AUTO EQUIPMENT CO. Aug. 10, 1956 [Aug. 12, 1955], No. 24552/56. Class 108(3) A hydraulic damper comprises a housing from which projects a plunger 19 connected to a piston 9 in a bore 5 at the opposite end of which is disposed a valve body 39 having a plurality of compression valves 51 spring retained in closed position and operable under liquid pressure due to piston movement, so as to permit liquid flow from the bore 5 to a chamber 6 which is closed by a flexible diaphragm 33, a spring loaded valve 75 controlling return flow of liquid to the bore 5, and resilient means 71 urging the piston 9 away from the valve body 39. The diaphragm 33 is of nylon fabric coated with Neoprene. The valve assembly 39 comprises four circumferentially-spaced piston valves 51 disposed in respective bores 41. Each valve 51 comprises an annular channel 57 which in the normal position of the valve (urged towards the bore 5 by a coil spring 59) is wholly covered by the wall bore 41. The channel 57 communicates with a bore 56 in the valve 51, which is open to the liquid in the bore 5. Pressure in the bore 5 is communicated to the space within the bore 41 on the other side of the valve 52 from the cylinder bore 5 by means of an axial passage 61 and transverse bore 63 in an extension 53 of the valve 51. A further extension 54 of the valve 51 operates in a respective bore in the end of the valve housing 39 against a pressure which is not maintained in conformity with the pressure in the cylinder bore 5. The rates of the respective valve springs 59 may be different, so as to result in a progressive. operation of the valves 51 as the pressure increases in the cylinder bore 5. Alternatively the respective channels 57 may be so disposed that they open to the passage 43 at different distances of travel of the valve 51. The gland 29 of the plunger 19 is resiliently mounted by means of a rubber bush 27 in the housing of the damper. The space between the diaphragm 33 and a housing cover 35 may be charged with air or nitrogen under pressure or may simply contain air at atmospheric pressure.

Title: Apparatus for handling veneers
IPC: B27L5/00
Filed: 1965-06-15
Abstract: 1,038,277. Woodworking. C. B. BOSSE. June 15, 1965 [June 19, 1964], No. 25279/65. Heading B5L. Apparatus for handling veneers cut from a log to a storage means comprises a transport device 3 for gripping the veneers as they are cut by a knife 2 and feeding them to a scanning unit 4 which ascertains the usable size of the individual pieces of veneer and feeds them to a cutting device 5 and a braking zone 7 wherein the speed of the usable pieces of veneer is slowed down from the cutting speed of the knife to the speed of the storage means to which the veneers are then fed. The scanning unit is electrical and determines the minimum usable size of veneer gripped by the device 3 as it is peeled by the knife 2, the device 3 being driven by a gear unit 1, Fig. 2 (not shown), synchronously with the peeling speed. The unit 4 controls the cutting device 5 which has four blades and is angularly rotated through 90 degrees to effect cutting of the veneer, the operative blade cooperating with a backing roller 5a running at the same speed as the cutter and the transport device 3. The cutting device is rotated during a cutting operation by a coupling 5b connecting the cutting device 5 to the transport device 3, a brake 5c holding the cutting device after the cutting operation. An ejector 6 controlled with the cutting device passes waste pieces to a disposal belt. Usable pieces enter the zone 7 where they are braked to the speed of the storage means which may increase during working; the speed of the storage means equals the veneer peeling speed divided by the as yet uncut part of the circumference of the treetrunk. An electrical scanning device 8 in the braking zone controls the speed of the storage means.

Filed: 1951-10-30
Abstract: 702,570. Valves. W-K-M INTERNATIONAL CORPORATION. Oct. 30, 1951, No. 25339/51. Class 135 A gate valve comprises a housing 10, Fig. 1, forming a valve chamber 11 having aligned ports 12, 13 provided with opposed parallel seats 14, 15, and expansible ported gate assembly slidable by a stem 24 and comprising members 25, 26 having parallel outer faces 29, 30 to engage the seats, and complementary opposed inner wedging faces 31. 32 which cause expansion of the assembly on to the seats upon relative movement between the members in either direction parallel to the stem 24. In the valve open and closed positions the appropriate end 33 of member 26 engages a corresponding abutment 34 in the chamber and continued movement of stem 24 causes the members to move apart on the seats. Expansion is prevented intermediate these positions by a bell-crank 35 pivoted in member 25 and having one arm 38 engaging a slot in member 26 and the other arm carrying a shoe 43 slidable between flanges 41, 42 of seat extension plates 17, 18 respectively. With the shoe between the flanges, the crank positions member 26 in an axial direction so that both surfaces 31, 32 contact. The flanges are recessed at 47 and 48 to permit the crank to pivot during expansion of the assembly in open and closed positions. In a modification, the gate assembly comprises members 55, 56, Fig. 12, having wedging faces 57 and expansion of the members on to the seats in the valve closed position is achieved by continued axial movement of member 55 after member 56 has contacted stop 58. Such expansion is achieved in the valve open position by so forming the flanges 41, 42 that the shoe 43 turns the arm 38 to move the members on to the seats.

Title: Improvements in or relating to polymerization process and product
IPC: C08F36/04
Filed: 1953-09-15
Abstract: Synthetic rubber is produced by copolymerizing an iso-olefin, e.g. isobutylene, with an aliphatic conjugated diolefin in a solvent for the monomers and resulting polymer, using 55 to 90 per cent (M) of monomers in the feed, at a temperature below - 50 DEG C., using as catalyst a solution in said solvent of a Friedel-Crafts catalyst, such as alumiium bromide or organic complexes thereof, to a maximum percentage conversion of 1000/M.  Diolefins specified are butadiene, isoprene, piperylene, 2-methyl pentadiene and dimethylbutadiene.  The solvents are preferably paraffin hydrocarbons in which the number of carbon atoms is M/10 - (1 to 2).  The polymerization may be carried out batch-wise or continuously and the polymer, preferably after catalyst deactivation, may be recovered by injection into hot water. The products have a larger average molecular weight than usual and more of the diolefin enters the copolymer.  As a result the polymers are more readily cured, e.g. with carbon black, sulphur and tetramethylthiuram disulphide, and will tolerate a higher percentage of plasticizer such as mineral oil.  The products also contain at least 2 per cent by weight of molecules having a viscosity average molecular weight above 1,300,000, as may be determined by fractional precipitation with acetone from benzene solution, and have an 8-minute Mooney of at least 40. Specification 595,120 is referred to.

In resistance welding, one or more spherical pellets of weldable metal are interposed between the surfaces of the workpieces and pressure and current are applied to cause the pellets to fuse with the surfaces of the workpieces. In one embodiment three spheres 11 are held in a pattern by upper and lower tapes 12, 13 adhesively secured together at 14 and are arranged between workpieces 20, 21 in the electrodes of a resistance welder. The tapes are ruptured by the welding pressure and the workpieces may be welded together with a slight gap therebetween or in close contact. The pellets may be wholly embedded by extrusion in a flexible strip of expanded polystyrene or by allowing polystyrene to expand and mould to embrace the pellets. The pellets may alternatively stand proud of the strip. A flexible strip of expanded polystyrene in which pellets are embedded may have adhesively secured to both surfaces strips of paper, plastics tape or metal foil. Pellets may be secured to a thin strip of polystyrene, plastics tape or zinc foil by adhesive or to a thin sheet of polystyrene or metal foil by a layer of polyvinylchloride or polystyrene which embraces the pellets by a vacuum forming process. The layer may be of box form or may wrap around the pellets. The pellets may be welded directly to a metal foil to form an assembly. Three or more workpieces may be welded together by placing pellets only between the lower pair of workpieces or between each pair of surfaces to be welded, the pellets in the adjacent layers being in line or staggered.
