Title: Improvements in the suspension of vehicles
IPC: B60G11/36
Filed: 1949-08-17
Abstract: 675,214. Vehicle suspensions. GREGOIRE, J. A. Aug. 17, 1949 [Aug. 17, 1948], No. 21427/49. Class 108(ii) In a vehicle suspension of the type comprising an additional coil spring which is inclined to the horizontal and acts eccentrically on the axle, a tie rod or the like is provided which absorbs the horizontal component of the force exerted on the axle by the coil spring and constrains the axle to move in the path it would follow in the absence of the coil spring. As shown, a variable flexibility is obtained by the additional coil spring 7 acting in tension on the arm 11 fixed to the axle 2. The tendency of the coil spring to twist the axle is resisted by the adjustable stay 14, which may be a rod pivoted at each end as shown, or may be flexible and fixed at its ends. If a flexible member is used, it preferably enters a bell-shaped socket at each end to prevent localized bending at the ends. Specification 674,224 is referred to.

Title: Improvements in double pipe lines and in methods of assembling them and of using them
IPC: F17D5/04
Filed: 1963-05-29
Abstract: 990,659. Multiple pipes; laying pipes. G. F. WITTGENSTEIN. May 29, 1963 [July 26, 1962; Nov. 23, 1962; Jan. 24, 1963], No. 21556/63. Heading F2P. A pipe composed of at least two tubes has an inner tube C1 inside an outer tube e1, the space between being filled with a liquid under pressure and being connected at at least one end with a chamber (Fig. 11, not shown), which feeds it with liquid if a leak occurs in the wall of either tube. The liquid may contain corrosion inhibiting, colouring or marking agents. The tubes may be of metal, plastic, cement or other suitable material and need not be circular in section. The outer tube may be made in two parts joined together. The inner tube C1 may be formed with an overlap as in Fig. 10, or may have exterior shapes as in Figs. 7 and 8; the purpose of the bend 40 in the sectional contour of the latter being to allow it to change shape under internal pressure. The inner tube may contain a gas for buoyancy and for this purpose may be split as in Fig. 12 into separate sections at 66, with external supports 62 for the tube C1 and by grometers 68 inside the sections to indicate leakage. In this instance the transported liquid is carried by the outer tube, but normally the outer tube is filled with water under pressure whilst the inner tube is used for transporting liquids. A pipe-line of the kind described above can be made by forming an assembly of one or more of the inner tubes C1 with its end 1 closed, and floating it into a corresponding assembly of the outer tubes C1 which have been partially filled with water. For this purpose the tube e1 may be laid at the bottom of a sloping trench and the water introduced by pumping, one end of the tube being closed, or the water may simply be allowed to run in from an adjacent lake &c. The advancing end of the tube C1 may be positioned in the tube e1 by wheels 10 and 11 arranged as in Fig. 4. Alternatively, a special two-port plug 23 is used to close one end of the tube el whilst the other is stopped by a flexible water-seal 21 held on a ring 20 as in Fig. 5. A water inlet 25 and a movable device 24 with an aperture 25 maintain the water at the required level. The closed end of the tube C1 supported on adjustable rollers 2, is advanced through the seal 21 to rest on supports 33 and to protrude its closed end into the central recess of the plug 23. The outer and inner sets of tubes are then joined by sleeves 6 and 34 respectively. Welding may also be used for joining the tubes as at 44.

Title: An improved spring suspension for telescopic forks for motor cycles
IPC: B62K25/06
Filed: 1952-08-27
Abstract: 734,097. Spring forks for motor-cycles. KRONPRINZ AKT.-GES. Aug. 27, 1952 [Aug. 27, 1951], No. 21566/52. Class 136(3). [Also in Group XXXII] In a telescopic fork for motor cycles in which each limb, Fig. 2, of the fork comprises two tubes 1, 2 sliding one inside the other, a spring arranged in the tubes 1, 2 is in two parts 3, 4 bearing against one another through a piston 5 slidable in the tube 1 and having a liquid throttling passage therethrough, for liquid which partly fills the tube 1. A rod 10 rigid with the tube 1 and having grooves 14, extends through the piston 5. Flow through the grooves 14 is controlled by a sleeve 13, which moves against controlling springs 11, 12 in accordance with the acceleration of the tube 1. In a modification (Fig. 1, not shown), the rod 10 and sleeve 13 are dispensed with, and an orifice adjustable by screw means, connects opposite sides of the piston 5. In a modification of the latter construction (Fig. 4, not shown), the orifice 8 opens into a closed chamber within the chamber formed by the tube 2. The liquid level in the device may be below the piston 5, or the liquid may extend partially into the closed chamber. In this construction, the orifice may be disposed in the wall of the closed chamber, instead of in the piston 5. There may be a plurality of the orifices. In Fig. 3, flow through the piston 5, via ports 18, is controlled by a spring-loaded piston valve 20, which also functions as an inertia mass. The chamber 17 in which the valve 20 is slidable, may contain air instead of liquid, or partly air and partly liquid.

In an embodiment an adsorbing element 6 containing silica gel, a molecular sieve or a zeolite in a tube 21 is fitted into member 10 which seals off the neck 5 of the reflector 1. The tube 21 connects to an annular groove 12 in the member 10 and the groove has an opening 18 for air to enter or leave the interior of the headlamp. The cap 13 has a bayonet fitting to the member 10 which may have a hole 17 in it or may be sufficiently loose to allow air to flow between it and the member 10. The tube 21 has a porous ceramic plug 16 which acts as a diffusion damper and a throttling device to prevent rapid passage of air through the element 6. In other embodiments the mask 22 is not connected to the tube 21, the porous ceramic plug 16 is replaced by a tube filled with metal or plastic filaments (28, Fig. 4, not shown) and the element 6 may be cranked or inclined towards the light source 4. In another embodiment, the diffusion damper and throttling device are provided by a tortuous passage through a cover (8, Fig. 1, not shown) on the outside of the reflector. The arrangement of the element 6 above the light source allows the source to heat up the element so that any air expelled from the headlamp removes moisture from the element whilst the throttling device prevents air from being expelled until pressure has built up in the lamp and also the element is thoroughly warm. In one embodiment (Fig. 4) a long tube 21 is used for the element so that part of it is hot and part cool.

Abstract: 1330722 End-stop switches; motor controllers ALLMANNA SVENSKA ELEKTRISKA AB 19 April 1971 [16 Feb 1970] 21838/71 Heading H1N In a device for controlling the repeated reversal of an electric motor (10), Fig. 1 (not shown), by operation of alternative relays 26, 27 Fig. 3, one fixed reversing position for one direction is determined by a micro-switch 15, Fig. 2 on anticlockwise rotation of cam 13 driven by a pilot control motor 14, and the reversing position for the opposite direction is successively displaced at each operating cycle as determined by a micro-switch 16 on an arm 18 which is moved step-by-step clockwise on each engagement by the cam 13. The forward and reverse rotation of both the controlled motor (10) and the pilot motor 14 is determined by the position of a relay 39 initially operated by start button 30 controlling a holding relay 35 with contacts 36 and 38. After each closure of the movable microswitch 16 a preset time delay relay 19 controlling contacts 46 delays opening of the circuit through holding relay 39 until the micro-switch 16 has been moved a short distance by cam 13. A freewheel and brake connection 17, 20 on arm 18 carrying the micro-switch 16 retains the arm 18 in position until the next operation at which it is rotated a further step. The final end stop rotation of the controlled motor (10) is determined when the arm 18 engages a preset microswitch 21 (not shown in Fig. 3). The system is stated to be used for operating scrapers moved progressively through greater distances and returning to the initial starting position and is particularly applicable to automatic scraper systems for cleaning out poultry-houses stables &c. or for feeding animals. Limit switches (11) (12), Fig. 1 (not shown), may determine the final rotational position of the motor (10) when the scrapers reach the extreme limits of movement. Modifications are referred to in which the reversing positions are varied at each end of the stroke and the stroke progressively reduced.

IPC: F16J10/02
Filed: 1967-05-11
Abstract: 1,220,075. Seals. DOWTY TECHNICAL DEVELOPMENTS Ltd. 17 May, 1968 [11 May, 1967], No. 21924/67. Heading F2B. The piston-rod of an hydraulically-operated piston is sealed by inner and outer seals 17, 18, the outer seal being loaded against the piston-rod by fluid pressure and at a pressure which, during outward movement of the piston-rod from the cylinder, is higher than that which prevails during inward movement. As shown, when the piston-rod is moved outwards to the left, the high pressure in the chamber 14 is in communication with the seal 18 by means of a passageway 24 and when the piston-rod is moved inwardly to the right, the low pressure in the chamber 14 loads the seal. The inner seal 17 consists of a bearing sleeve with or without a sealing ring 26. In Fig. 3 (not shown) the fluid pressure acts radially on the outer seal and a vent (32) is provided between the seals to prevent pressure fluid within the cylinder chamber (15) from reaching the outer seal. In Fig. 4 (not shown), the fluid pressure to the piston and seal is controlled by a hand-operated spool valve, the high and low pressures in the lines (37, 38) being connected to both the cylinder and seal so that as the piston-rod is moved outwardly, the high pressure fluid is conducted to the other seal. In an arrangement, such as an hydraulically-actuated vibrator, Fig. 5 (not shown), in which a piston (13) continues to move in the same direction after the pressures in lines (21, 22) are reversed, a shuttle valve is employed in the line (22) to connect high and low pressure lines (37, 38) with the outer seal through a line (50). Spring- urged valve discs (53, 54) control passages (58, 57) through the shuttle valve as the valve is shifted between end stops (51, 52) by the flow of fluid through the line (22).
