Abstract: 1,115,890. Vehicle suspension. MONROE AUTO EQUIPMENT CO. 10 March. 1967, No. 11435/67. Heading B7D. In a motor vehicle independent suspension, the piston-rod 15 of a tubular hydraulic vibration damper is detachably connected at its upper end to a bearing 29 resiliently mounted in the vehicle body. The cylinder part of the damper comprises a pair of concentric tubes 67, 65, mounted within a tube 16, being positioned by means of a cap member 75 of the cylinder and the threaded end 18 of a ball joint member 17 which co-operates with a socket member 14 detachably secured to a suspension arm. The wheel spindle 19 has a sleeve 23 secured to the lower end of the tube 16. The suspension coil spring 26 is located between an upper support member 30 clamped between the bearing 29 and a shoulder on the piston-rod 15, and a lower support 28 welded to the tube 16. By removing the nut 35 at the upper end of the piston rod and the ball joint member 17 from the tube 16, the vibration damper may be readily removed from the vehicle, the suspension spring 26 being retained between the bearing 29 and the member 28. Damping orifices controlled by flap valves are provided in the piston 85. Orifices closed by flap valves are also located in a member 73 closing the lower end of the inner cylinder 67, the space below the member 73 being connected with the space between cylinders 65 and 67 through apertures 69. The orifices in the piston 85 impede its upward and downward movement in the cylinder, and those in the member 73 permit the flow of fluid to and from the space between the cylinders 65 and 67 to compensate for the differences in volume above and below the piston due to the piston-rod. To cushion the impact at the ends of the piston stroke, resilient members 143 and 150 are" provided A guide member 81 having an absorbent, resilient sleeve 83 is provided at the upper end of the inner cylinder 67, the sleeve being kept moist by liquid passing through apertures in the member 143. A removable cap 49 protects the bearing 29 and the vibration damper is protected by a member 152.

Abstract: 217,709. Ferguson, S., Pailin, G., and Ferguson, Pailin, Ltd. April 28, 1923. Oil switches; switch-boards.-In armour-clad, draw-out type switch gear with duplicate busbars, the ordinary oil switch is adapted to serve also as the selector switch by mounting the busbars immediately above the oil switch which has three sets of contacts per phase so arranged that the centre or circuit contact of each phase may be connected to either or both of the outer or bus-bar contacts of that phase. One phase is shown in Fig. 2 in which duplicate bus-bars a, b and the central phase conductor are connected to fixed contacts d, f, e in the oil tank by vertical plugs c supported by the tank cover o. The movable contacts g, h, i. j are carried by two bridges k, m controlled by handles n, as described in Specification 203,101, or electromagnetically. Interlocking mechanism ensures that one only of the bus-bars is connected to the common central contact, but this mechanism may be rendered inoperative and both bridges closed together so that the switch may serve as a busbar coupler. When, as shown in Fig. 4, the tank and its cover are lowered, by means of the screwed pillars u, nut 4, and a worm and wormwhee,l driven from a small motor so that the plugs are disconnected, pivoted catches k serve to hold the cover, and the tank may be unbolted and removed. The catches engage projections r on the tank in the raised position and serve to support it. The oil tank may have, in its cover, an oil separator 5, Fig.. 7, a baffle plate 6 being provided to direct the oil to the bottom of the chamber and a valve 8 to admit the oil to the tank. The free gases pass through the vent 7.

Abstract: 723,253. Discharge apparatus. SORENSEN AKT.-GES. May 7, 1952, No. 11572/52. Class 39 (1) Incorporated within the envelope of a diode is a switch which, on failure of the filament, short circuits the filament to the plate. The switch is a resilient spring wire, shown diagrammatically at 26, slightly constrained out of its normal position so as to hold under tension the attached filament 22. If the filament breaks, spring wire 26 is released to make contact with a lead wire 30 electrically connected to the plate 20, which is thus directly short-circuited to the filament lead 17. The diode can be used as part of a voltage regulator circuit, as described in Specification 723,300, [Group XXXV], Specifications 654,116 and 661,872, [both in Group XXXV], also are referred to.

Title: Improvements in methods of producing diffusion metal layers, and in particular layers consisting chiefly of chromium, on metallic articles
IPC: C23C16/08
Filed: 1953-04-27
Abstract: Superficial diffusion alloys of addition metals, such as chromium, are formed on bases of iron, nickel, cobalt or their alloys by halide diffusion, the halide vapour being formed by the action of heat alone on a 'cementation product' which (a) has been formed by the reaction of a hydrogen halide upon suitable substances, the reaction products having been heated to 100-600 DEG C. to eliminate residual hydrogen halide and (b) contains at least one auxiliary compound serving to perform a secondary function such as sweeping the initial atmosphere from the reaction container, homogenizing the atmosphere in the reaction container or superficially decarbonizing the articles under treatment.  The lest traces of acid may be removed from the concentration product by the addition of gaseous ammonia or ammonium carbonate.  The halide is preferably a fluoride and regeneration chromium may also be present.  The auxiliary compound may be ammonium fluoride or a halide of tungsten, molybdenum, nickel, cobalt, manganese, thorium or beryllium and may be formed in situ by reaction between the appropriate oxide, which may have been calcined or partly reduced, and the addition metal chloride.  Diffusion may be carried out in containers which are fluid tight except at a leakage zone remote from the cementation product, in a furnace having a neutral or reducing, e.g. hydrogen atmosphere, excess formation of addition metal halide being avoided by the use of appropriate quantities of reactants.

The braking-cords may be attached to pegs or hooks or to an adjustable rod, which may be moved to adjust the braking effect on all the spindles of one rail. The single sided creel illustrated is for mill warping. Double sided creels may be used.
