Title: Improvements in and relating to the suspension of motor road vehicles
IPC: B60G17/027
Filed: 1922-10-07
Abstract: 210,821. Holle, A. A. Oct. 7, 1922. Laminar springs. - The effective length of the suspension spring of a motor vehicle is varied by means controlled by hydraulic pressure generated by the motor, or by the vehicle when in motion, so that the flexibility of the springs varies in an inverse ratio to the speed of the vehicle. One or each end of the springs 1 is mounted on the frame between a plate spring 5 and a roller 3 movable longitudinally in a slotted guide 4. The rollers 3 are connected by rods 10 and levers 8 to the rods 9 of pistons 7 arranged in a cylinder 6 supplied with pressure fluid by one or more pumps driven from the engine or running gear of the vehicle. The sliding supports of the ends of the springs may be replaced by a swing- ing support. The Provisional Specification describes a modified form of sliding support.

Abstract: 1302475 Rotary shaft seals SONESSON PUMPINDUSTRI AB 19 April 1971 [17 April 1970] 27212/71 Heading F2B A device for maintaining in a rotary pump seal chamber 7 filled with liquid or gaseous sealant a predetermined pressure relative to the centre of the impeller of the pump comprises a container 9 filled with sealant and having an inlet 16 and an outlet 10 both connected to the seal chamber and a bellows 14 within the container in communication at 17 with the pump chamber at 15, the bellows being adapted to expand axially in response to a reduction of quantity of sealant in the seal chamber (due to leakage from the seal chamber into the pump chamber) and a compression spring 18 being provided to counterbalance the spring force inherent in the bellows. The seal chamber 7 contains end-face seals 5, 6 and the sealant is circulated back to the container 9 by pumping blades 13 where it is cooled either by a cooling coil 35 having an inlet 36 and an outlet 37 or by cooling fins on the container. Sealant is replenished in the container 9 automatically through a feed device when the bellows has expanded to its maximum position 27; a permanent magnet 31 secured to the bellows by a bracket 32 operates a switch 33 to control the feed device which is shut off again when the bellows returns to the full position 30. The bellows may be made of stainless steel and the compression spring 18 may be designed to counterbalance the spring force of the bellows when the bellows is in either the maximum position 27 or the full position 30.

A textile material composed of a synthetic polymer is softened by applying thereto a quaternary ammonium salt having the formula [R.CO.NH-CH 2 N#]<SP>+</SP>X<SP>-</SP> in which R.CO is an acyl group derived from a fatty acid having at least 10 carbon atoms, N# is the nitrogen atom of a heterocyclic tertiary amine and X is the monovalent anion of an acid and then heating the material at 100‹-200‹C. The acyl group RCO may be decanoyl, dodecanoyl, hexadecanoyl, octadecanoyl, octadecenoyl or an acyl group derived from palm oil or cottonseed oil and the heterocyclic amine group may be of pyridine, apicoline or lutidine, quinoline, or an N-alkylpiperidine or N-alkylmorpholine. The anion X may be chloride, bromide, nitrate, hydrogen sulphate, m-nitrobenzoate or mnitrobenzene sulphonate. Specified quaternary ammonium salts are stearamidomethylpyridinium chloride or nitrate, oleylamidomethylpyridinium chloride, lauramidomethylpyridinium hydrogen sulphate, stearamidomethyl quinolinium hydrogen sulphate and stearamidomethyl - N - methylmorpholinium chloride. The quaternary ammonium salt may be applied to the textile material from an aqueous solution or suspension which may contain 0.003-0.2% by weight of the quaternary ammonium salt. The aqueous suspension may be prepared by dissolving the salt in a water miscible liquid, e.g. methanol or ethanol, and then adding this to water and may contain a non-ionic dispersing agent. During deposition of the quaternary ammonium salt on the textile material the solution or suspension may be slowly heated to a temperature not exceeding 60‹C and maintained at this temperature. The textile material may then be dried at a temperature not exceeding 100‹C and then heated at 100‹-200‹C for 1-10 minutes. 0.1-5.0% by weight of the quaternary ammonium salt may be deposited on the textile material. Fibres, filaments, rovings, yarns, non-woven webs or woven or knitted fabrics made from polyamide, polyester, polyacrylonitrile or modified polyacrylonitrile may be treated.

Abstract: 1478939 Controlling reactors COMBUSTION ENG Inc 1 July 1975 [1 July 1974] 27745/75 Heading G6C [Also in Division B8]  A linear motion device 10 for moving a control element 12 is shown provided with a tubular housing 14 formed of ferritic steel and capable of withstanding internal pressures of 2,000 p.s.i., being sealed at its lower end to a nozzle 16 extending out of the top of a nuclear reactor pressure vessel (not shown), the element 12 extending into the reactor vessel. Four solenoid coils 20 are mounted adjacent recesses 18 in the housing 14 and form spaced solenoids A, B, C, D supported in a structure 22 supported by a shoulder 24 on the housing 14. Similar upper and lower gripper assemblies 42, 44 are arranged to be brought into latched position with respect to spaced projections 90 on the element 12 by energization of the respective coils B, D causing support members 46, 48 to move to close gap 86 therebetween (gripper assembly 42 is shown latched, while gripper assembly 44 is shown unlatched). Energization of the solenoid A or C causes the respective support member 46 to be moved upwardly, thereby causing movement of gripper assembly 42, 44 upwardly relative to the housing 14, (gripper assembly 42 is shown in its upper position). The various spacings between the projections 90, between the upper and lower positions of the gripper assembly 42, between the upper and lower positions of the gripper assembly 44 and between the gripper assemblies 42, 44 and the projections 90 when one assembly is latched and carrying the load and the other is in coupled position (i.e. in latched position but not carrying the load) are all predetermined. Two incremental movements are achieved in each cycle of operation (i.e. movement of the member 12 by the spacing between respective portions of adjacent projections 90) by operation of the solenoids A, B, C, D to cause the gripper assemblies 42, 44 to act step-by-step to lift the element 12 part of the required distance in turn and to transfer the load from one to the other, Figs. 2a to 2i (not shown). In a similar manner the element 12 may be lowered step-by-step, Figs. 3a to 3i (not shown).

[Classes 83 (ii) and 83 (iv)] Welding; pipe-end closing.-Vessels such as electric discharge tubes and lamps, particularly metal bulb discharge tubes, have their metal pumping and filling tubes closed so as to seal the vessel hermetically by first heating the tube to welding temperature and then effecting the welding by separate pressure tools. Heating may be effected by gas flames to a temperature above the welding temperature so that pumping may be carried out during this operation, the tube being allowed to cool slightly before the closure is effected by a single or multi-part tool. The tools may consist of heat resisting alloy steels such as ferro-chrome, ferro-nickel, ferromolybdenum, and are preferably of the impulse type driven forward by a pneumaticpiston and returned by a spring &c. and having a pressure of several kilograms. One of the tools may be so actuated and the other may function as an anoid. The tools may also be provided with cutting edges to even off the waste. Dielike tools may be used in order to prevent thickening of the tube at the closed end, so that tubes of larger diameter may be used..Specification 406,185, [Group XI], is referred to.
