Title: Improvements in hydraulic shock dampers
IPC: F16F9/26
Filed: 1932-04-12
Abstract: 396,497. Hydraulic shock-absorbers. ELLIOTT, A. G., Wickesfield, West Wittering, near Chichester. April 12, 1932, No. 10467. [Class 108 (iii).] In an hydraulic shock-absorber particularly for vehicles the passage of liquid from a compression chamber or chambers, formed for example between the ends of a double piston b and its cylinder, is controlled by a valve e<4> or valves in the communicating passages e<1> and e, e<2>, e<3>, the resistance of a spring f acting on the valve being varied automatically by varying the pressure in one or more variable pressure chambers, formed between a stepped piston g and its cylinder, to which liquid is delivered by one or more pumps operated by an oscillating member of the shock absorber. One end of the valve e<4> may be reduced at f<1> to provide for a greater compression of liquid at one end of the cylinder than at the other, and consequently a greater resistance to movement between the axle and chassis frame in one direction than in the other. The pump comprises a plunger h<2> having teeth h<3> meshing with teeth h<4> on the shaft c<1> of the rocker arm c which operates the piston b and is connected to the axle. In operation, movement of the plunger h<2> sucks oil through a spring- pressed non-return ball-valve i<5> and forces it, with a pressure varying with the movement of the rock-shaft, through a similar valve j<3>, pipe j<7>, union j<8>, and passage j<10> to the space behind the piston g from which it escapes around the piston and passes to an oil reservoir open to the space between the ends of the piston b. The liquid may be pumped directly into the variable pressure chamber from one or more of the compression chambers by the oscillating piston itself. According to the Provisional Specification the variable pressure chamber is connected by a pipe with another compression chamber which is adapted to vary the pressure on the controlling valve. Reference is made in the Provisional Specification to Specification 372,445.

IPC: B21D51/32
Abstract: 105,696. Jackson, W. J. Mellersh-, (Stetson, F. F.). Aug. 17, 1916. Seaming.-Can bodies are fed continuously through a machine in which the ends are fed and applied to the cans and then seamed in two successive operations. The bodies are fed by a rotating table 54, Fig. 1, having arms 55, into pockets 58 of the rotary carrier 56, in which they are retained by a curved rail 59 and by which they are moved below a supply of can ends arranged between rods 60. The body in passing actuates a lever 70 which withdraws a support 64 and allows the lowest end to rest on a pair of rails 65, 66, Fig. 22, just above the body. The carrier 56 has tongues 73 which move the can ends between curved rails 59<1>, 68 keeping them directly over the bodies which rise as they pass over an inclined support 74 and are thus pressed against the ends. The assembled can passes between chucks on a rotary carrier 91, Fig. 2, the lower chuck 86 being moved up by a bowl 79 in a cam groove 80 to clamp the can. The upper chucks 96, Fig. 11, have gears 94 engaging a stationary gear 95 so that they rotate and each has also a ring 98 normally held concentric with the chuck by spring-pressed balls 99 but which is acted on by a fixed cam 107 to roll over the seam. The can bodies are then transferred to chucks on the rotary carrier 119 by a rotary double fork 109. The lower chucks 110 are moved like the chucks 86 to clamp the cans and the upper chucks 122 are rapidly rotated by gears 123, 124, shaft 36, and bevel-gear 34. While the cans rotate, the seams are pressed by rollers 125 carried by adjustable bell-crank levers 127 having bowls running on a fixed cam 130. The cans are removed from between the opened chucks by a rotating arm 131. To prevent the cans sticking to the chucks 96, 122, ejector rods 132, 133 are arranged in them and adapted to be operated by arms 138, 139. The chucks 86, 110 are adjustable by central screws and have yielding springs 90.

Patent GB-958085-A (GB)
Title: Process for the manufacture of alkyl tin trihalides
IPC: C07F7/22
Filed: 1962-03-20
Abstract: Alkyl tin trihalides may be made by reacting a tetra-alkyl tin with tin tetra-chloride, -bromide or -iodide in the molar ratio 1:2.  The reaction takes place in two stages which may be carried out independently: SnR4=SnX4--->RSnX3+R3SnX R3SnX=SnX4--->RSnX3+R2SnX2 Using short, unbranched chain alkyl groups the reaction may be initiated at between 0 DEG  and 20 DEG C. and is faster than when using longer or branched chain alkyl groups, which require initiation at elevated temperatures.  The process is preferably carried out by adding the tetraalkyl tin dropwise to the tin tetrahalide, thus ensuring an excess of the latter throughout the reaction.  If desired, the tin tetrahalide may be used as a complex, e.g. with an ether.  The product, which contains RSnX3 and R2SnX2 may be separated into its constituents by distillation.  The process may be modified using a trialkyltin halide in place of the tetraalkyl tin.
