Title: Hydraulic cylinder device for lifting and lowering a pivotable drivers cab
IPC: B62D33/07
Filed: 1973-05-23
Abstract: 1383884 Hydraulic actuators DOMKRAFT AB NIKE 23 May 1973 [3 Nov 1972] 24609/73 Heading F1D An hydraulic actuator for tilting a vehicle cab has grooves 14, Fig. 4 in the walls of the cylinder and an auxiliary piston 21 at that end of the cylinder towards which the main piston 15 retracts when the cab is being lowered. The grooves 14 connect the chambers on opposite sides of the piston 15 when the cab is resting on resilient supports in its operative position. When fluid is supplied to the actuator to raise the cab the piston 21 pushes the piston 15 until a seal 18, 19 on the latter has cleared the top of grooves 14. At this point a seal 22, 23 of the piston 21 is by-passed by the grooves 14 so the piston 21 does not move any further up the cylinder. When the piston 15 descends it abuts a spring 26 attached to the auxiliary piston 21 and moves the latter to the bottom of the cylinder. A check valve in the piston 21 permits fluid-flow through the piston from right to left as the main piston is descending.

Abstract: 348,102. Photographic processes. GROVES, W. W., 30, Southampton Buildings, London.-(I. G. Farbenindustrie Akt.- Ges. ; Frankfort-on-Main, Germany.) Aug. 13, 1929, No. 24725. [Class 98 (ii).] Sensitive layers containing, in admixture with a sensitizer, basic dyestuffs which are rendered partially or completely colourless by the action of light are fixed, after exposure under a negative or original, by treatment with a solution of hydrofluoboric acid or a salt thereof in a solvent, such as water or alcohol, having the property of dissolving the sensitizer contained in the layer. The dyestuffs are thereby converted into insoluble borofluorides. Successive treatments with a concentrated solution to convert the dyestuff and a dilute solution to dissolve the sensitizer are preferable. A gelatin layer containing anilidoflavinduline chloride, and sensitized with thiosinamine, may be fixed after exposure by washing first for 2 minutes in a 12 per cent aqueous solution of sodium borofluoride, and then for three or four periods of 15 minutes in 1 per cent aqueous solutions of the same salt.

Title: Improvements in means for determining the presence or absence of a body at a particular location
Inventor: DRYDEN THOMAS FERLIE
IPC: G01F23/296
Filed: 1954-08-30
Abstract: 814,523. Electric tests. BABCOCK & WILCOX Ltd. Aug. 30, 1955 [Aug. 30, 1954], No. 25108/54. Class 37. [Also in Group XL (c)] The height of a liquid or solid fluent material in a tank is controlled by means of a probe in the tank which constitutes the termination of a. line connected to a circuit which provides pulses of high-frequency current, the arrangement being such that contact of the material with the probe suppresses the pulses, a relay being so connected as to change its state according as the pulses are suppressed or not. As shown, an alternating voltage feeds triode 17 forming part of the oscillatory circuit and a further triode 15 through the winding of relay 9. The anode circuit of triode 17 contains tuned circuit 25, 27 and is coupled to a winding 29 in the cathode circuit to produce 30 megacycles per second oscillations during alternate half-cycles of the A.C. supply. The grids of triodes 15, 17 are coupled together and earthed through a circuit 43, 45 having a time constant of 0.005 seconds. When the circuit is oscillating a negative charge builds up across the circuit reducing the current through triode 15, thereby preventing relay 9 from energizing. The oscillator load is constituted by two parallel connected transmission lines 55, 57 which terminate in probes 63, 65 inside the tank. These probes constitute, with the conductive wall of the tank, capacitors. By adjustment of capacitor 27 the oscillation frequency is such that the transmission lines length will produce a phase shift which will tend to inhibit oscillation. In operation, when the level covers the upper probe 63, the oscillation will be inhibited, the current through relay 7 will increase and will connect the second transmission line in parallel by means of its contact 71. When the level falls below the lower probe, oscillations will recommence and probe 65 will be disconnected. Further contacts operated by relay 9 may be used to give visual warning if the level is above the upper or below the lower probe. Contacts may also be provided which control valves to cut off the flow of material if the level rises above probe 63 or to introduce material if the level falls below probe 65. The Specification describes in detail (Figs. 2 and 3, not shown) two suitable probe constructions and their mounting in the tank, one (Fig. 2) consisting of a steel rod passing through two frusto-conical porcelain insulators and the other of a mild steel probe passing through discshaped insulators. Channels are provided by which compressed air is forced into the tank around the probe so as to prevent material such as damp polarized coal from clinging to the rod.

Filed: 1959-07-23
Abstract: 953,323. Brake lining retraction means. GIRLING Ltd. July 22, 1960 [July 23, 1959], No. 25262/59. Heading F2E. In a friction brake the retraction of a friction member from a co-operating surface in the off position of the brake is effected by the engagement of a retraction device at all times with a part of a resilient member which engages with the material of the friction member. In the disc brake illustrated, in Fig. 3, each friction pad 17 is engaged at its periphery by a resilient finger 26 of a resilient steel spring strip 23, the finger 26 urging it away from the disc surface, the movement of the finger being limited to the amount permitted by slot 27 in a web 25 of a plate bolted to the calliper housing; the clearance being only sufficient to provide a predetermined clearance between the pad and the disc. When the pad wears and its movement towards the disc becomes greater than that permitted to the finger by the slot 27, the pointed end of the finger ploughs a groove in the friction material during the excess part of the pad movement so that it takes up a fresh position in the pad displaced from the previous position by an amount equal to the pad wear. On release of the brake the finger again retracts the pad through the distance permitted by slot 27 so that a substantially constant clearance between the pad and the disc is maintained through the life of the pad. A second finger 28 may be provided on the inner side of the pad to ensure even engagement thereof. Instead of engaging beneath the surface of the friction material, the end of the finger 36 may be made flat (Fig. 7), to bear against the surface of the pads instead of ploughing grooves therein. Specifications 742,338 and 828,961 are referred to.
