[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 4, 1934] [Class 108 (ii)] In a motor &c. vehicle of the kind in which a main axle is guided on the frame or on a part connected thereto by means of substantially vertical guide tracks, the axle is guided and restrained from lateral movement by means of a single pair of rollers or shoes, p<1>, p<2> arranged at the same level in the same transverse plane and bearing against opposite sides of a central track o<11>, thus permitting the axle also to execute a swinging movement about a central longitudinal axis between the two rollers. In the arrangement shown in Fig. 1, the rollers are mounted upon the axle, and the guide-track o<11> is carried upon a transverse frame member a<2> ; while in another arrangement, Fig. 2, the rollers mounted on the axle g are guided upon a track formed directly on the differential casing c, which is secured to the vehicle frame. For securing greater resilience either the guide tracks or the rollers are made resilient, but preferably this is achieved by constructing the rollers of rubber. The axles are sprung by means of helical, preferably unguided springs disposed between the axles and vehicle frame. The axle g may, as shown in Fig. 2, with two struts i<1>, i<2>, form a triangular structure which is pivoted at n to the frame. If desired, the vertical track may be carried by the axle and the guiderollers or the like by the vehicle frame.

Abstract: 918,167. Making pure tungsten or molybdenum, electrolytically. SLATIN, H. L. Feb. 4, 1960, No. 4040/60. Class 41. Pure tungsten or molybdenum are made in crystalline form, by electrolysis using as electrolyte a fused mixture of an alkaline earth halide and an oxide, preferably CaO which forms a clear melt, to which tungsten or molybdenum tri-oxide is added. For example, CaCl 2  30 to 80%, CaO 10 to 35%. MoO 3  10% or WO 3  30 to 40%. A little CaF 2  may be added to CaCl 2 . Calcium tungstate or molybdate may be used instead of the oxide. Electrolysis is effected at 1050‹ C., in an inert gas, and with a current density per sq. inch of 10 A. at the anode and 10 to 70 A. at the cathode. A carbon anode may be used and an iron cathode, but the process may be applied to refining impure W or Mo when these impure metals are used as anodes. The electrolyte should be free of alkali metal compounds, e.g. phosphates, nitrates, carbonates which tend to discolour and form compounds with the deposited metal. The cathode with metal crystals thereon is freed from electrolyte by washing with dilute HCl.

Condensers have plates of tin-foil or similar foil, the thickness of which is small compared with that of the dielectric.

Abstract: 1419951 Centrifugal compressors LUCAS INDUSTRIES Ltd 24 Jan 1973 [29 Jan 1972] 4312/72 Heading F1C [Also in Division G3] A pressure control arrangement for an air compressor 10 comprises a Venturi 12 through which air-flows from the compressor via an outlet passage 13 to an external apparatus, a Venturi 14 through which air can flow from the compressor to atmosphere, and a valve 19 operated by a piston 20 responsive to an increase in a pressure signal at the throat of Venturi 12 or to a decrease in a pressure signal derived from the pressure at the throat of Venturi 14, to spill air at 18 from the downstream side of Venturi 12. The throat area of the Venturi 14 is one hundredth that of Venturi 12, while a restrictor 15 limits the mass flow through Venturi 14 to approximately one hundredth that through Venturi 12 under normal load, the pressure in the throat of Venturi 14 then being just sufficiently longer than that in Venturi 12 to overcome the force of a spring 21 and close the valve 19. A variation of load leading to a rise in the pressure in Venturi 12 causes the valve 19 to open to spill air until the piston 20 is again in equilibrium. If the pressure in passage 13 rises sufficiently, it acts through a bellows 26 against the action of a spring 27 to open a salve 25 to vent the throat of the Venturi 14 to atmosphere, thereby causing valve 19 to open wide.
