Title: Improvements in shock absorbers
IPC: F16F9/22
Filed: 1930-03-11
Abstract: 342,935. Hydraulic shock-absorbers. ARMSTRONG, F. G. G., 14, York Road, Beverley, East Yorkshire. March 11, 1930, No. 7850. [Class 108 (iii).] In an hydraulic shock-absorber for vehicles, cooperating elements such as a cylinder and piston are respectively connected to two pivoted arms mounted one on the frame and the other on the axle, the connection between one of the co-operating elements and its arm including flexible means. In the construction shown in Fig. 1, the two arms 10, 11 are connected respectively to the frame and axle at their ends 12, 13, and the arm 11 has rigidly secured to it a plunger 15 which works in a cylinder 16 enclosed in a reservoir 17 connected to the other arm 10 by a flexible member 29 passing over a curved guide 28 on the arm. When the plunger 15 moves outwardly, liquid flows freely from the reservoir into the cylinder 16 through a one-way valve 20 which works on an extension of the rivet 18 connecting the cylinder 16 to the reservoir. Inward movement of the plunger is resisted by the flow of the liquid out of the cylinder through a restricted orifice controlled by the adjusting screw 23. In a modification the cylinder, reservoir, and piston are arranged on the other side of the pivot 14 connecting the two arms 10, 11. Several constructions are described, one being shown in Fig. 4, in which pistons 35 arranged on opposite sides of a pivot 39 work in cylinders 33 mounted on the frame of the vehicle, the pistons being connected by a flexible member 37 to a sector which is oscillated by an arm 38 connected at 41 to the vehicle axle.

Abstract: 1,208,716. Weft measuring devices, shuttleless looms. GEORG FISCHER A.G. BRUGG. 14 Feb., 1969 [16 Feb., 1968], No. 8280/69. Heading D1E. A weft measuring device comprises a number of levers 24 which pivot in succession to draw the weft into loops and which return in succession to their original position to leave the loops unsupported for easier picking. The levers are cam operated and then ends 30 protrude through slots in a box whose wall is curved and has a cover 32 with abutments 38b providing channels 33 into which the weft is drawn by the levers 24, the curved shape of the channels enabling the weft to remain, by its own weight, in loops when the levers retract. The weft is held by a clamp 39 during drawing into loops and picking commences whilst the last levers are drawing loops, continues when all levers have retracted thus drawing weft directly from the supply, whereupon a clamp 17 closes. Prior to the next measuring operation an additional lever 24z outside the clamp 39, may pull back the weft in the shed. The weft during picking is tensioned by a brake 18. A number of the devices may operate on a loom having weft selection.

Title: Improvements in or relating to coin controlled devices
IPC: G07F5/10
Filed: 1938-03-18
Abstract: 512,900. Coin-freed apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd, and DOLMAN, H. J. March 18, 1938, No. 8327. [Class 27] Coin action, weight and multiple-coin.-In coin-controlled apparatus in which a coin or coins tilts a counterbalanced weighing scale the movement of which is utilised to effect the operation of the mechanism controlled, the return movement only of the scale is utilized so that the full action of the counterweight is available for that purpose. The scale 1 is pivoted at 2, Fig. 2, in a yoke 4 and has a scale pan 5 with projections on which the coin 28 rests. It has an arm 7 with a weight 6 screwed thereon, the arm working between limiting stops 8, 9. A lever 13 is pivoted at 14 in a slot 12 in a disc 11 which is carried by the pivot shaft of the scale, one end 15 of the lever 13 being weighted to rest on the bottom of the slot. When the scale tilts under the weight of a coin or coins, the other end 27 of the lever 13 meets a pin 26 on a crank arm 25 extending from a cam 22. The lever 13 is thereby rocked counter-clockwise until the end 27 passes under the pin 26. When the coins fall off, the scale is returned by counterweight 6 and the end 27 of lever 13 now rotates the crank 25 and cam 22 since the lever 13 cannot rock clockwise. A resilient contact member 21 bearing a contact 24 rests on the cam 22 and is moved by the rotation of the cam so that the contact 24 engages a contact 23 on a second resilient strip 20. The members 20, 21 are included in an electric circuit which effects operation of the apparatus it is desired to control. The return movement of the scale may be utilized to release a trigger and thus permit a spring operated device to come into action. Specification 23,407/96, [Class 27], is referred to.

Abstract: 719,245. Treating wood. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES (O.N.E.R.A.). April 3, 1952 [April 3, 1951; March 14, 1952], No. 8520/52. Drawings to Specification. Class 140. Wood, e.g. veneer, is reduced to its cellulosic structure by treatment with chlorine dioxide either as a gas, or by immersion in an aqueous solution of sodium chlorite containing an organic acid reacting therewith to yield chlorine dioxide, the treatment being continued until substantially all the lignin is removed, the resulting cellulosic structure being then steam treated and/or washed and dried. The product may be used as such, or may be impregnated with melamine-formaldehyde resin and hot-pressed to cure the resin and, if desired, to shape the wood. The organic acid may be acetic or formic acid added at intervals to reduce the pH from an initial value of 6 to 3.5, after which the veneer is removed, washed, dried, and retreated once or oftener until the desired lignin removal is attained. In the gaseous treatment, the wood may be treated in a chamber with a continuous stream of chlorine dioxide, or a given quantity may be admitted and periodically replaced. The chlorine dioxide gas may be diluted with carbon dioxide or may act on the wood in the presence of an amine or pyridine to neutralize hydrochloric acid evolved. Before the gas treatment, the wood may be soaked in acetic acid. The melamine-formaldehyde resin may be applied as a powder to moistened veneers and allowed to diffuse into the wood, or as an aqueous solution applied to the dried veneers by spraying or dipping.
