Abstract: 836,290. Pneumatic tyres. COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN. Feb. 17, 1958 [Feb. 16, 1957; June 3, 1957], No. 5156/58. Class 144 (2). A pneumatic tyre has a crown reinforcement of rubber embedded cord plies, the cords of which are crossed in at least the central band of the reinforcement and the side bands of the reinforcement flanking said central band having a greater resistance to flexure under the influence of forces tending to produce side slip of the tyre tread. The greater rigidity of the side bands may be effected by a smaller cord angle or by the use of cords or embedding rubber of different physical characteristics from those in the central band. The plies of the respective bands may be independent, either abutting or overlapping, Fig. 7, at the adjacent side edges of the bands, or at least one of the central band plies may extend continuously across the full width of the reinforcement, Fig. 6. The central band may be three times as wide as each side band, and where the adjacent band plies overlap such overlap may be for one-quarter to onesixth the width of the central band. The crown reinforcement may comprise a ply of radial cords extending either the full width of the reinforcement or across each side band only, in which latter case such plies may comprise extensions of carcase plies. The carcase may be devoid of cord reinforcement or may comprise bead to bead radial cord plies. Fig. 1 shows side bands 1 and 3 of cross-laid plies of cords 4, 5 and 41, 5<SP>1</SP> subtending a cord angle with the circumferential direction of from 0 to 30 degrees, and a central band 2 of cross-laid plies of cords 6, 7 having a cord angle of from 15 to 50 degrees, the reinforcement including a full width ply of radial cords 9. The cords in each ply may be discontinuous short lengths or may be continuous across the reinforcement as shown in heavy lines in Fig. 2. The reinforcement may comprise embedding rubber of higher modulus of elasticity than the tread rubber. Specifications 628,060, 677,166, 698,915 and 789,770 are referred to.

IPC: B60R17/02
Filed: 1916-04-12
Abstract: 102,319. Ferguson, J. B. April 12, 1916. Force-feed lubricating.-The bearings of the gearbox, universal joints, and driving- axle of a motorvehicle are supplied with oil under pressure through internal passages from a pump, which may be that which lubricates the engine. The oil passes through the shaft B to passages in the lay shaft D, lubricating the bearings in the gear-box A, and also through passages in the universal joint E, propeller shaft G, and rear axle casing H to the bearings of the axle K. Extensions of the passages lead to the spindles K<4> of the brakes and to the spring connexions by means of rigid or flexible pipes. The oil collecting in the casing H returns along the torquetube M, through which it may be driven by a rotary impeller G<2> on the shaft G. In a modification, the gear-box is integral with the axle casing H and universal joints are placed along the back axle, the bearings being all lubricated by passages in a similar manner. The oil leaking from the outer axle-bearings H<6> may be trapped and returned to the pump by flexible or other tubing.
Patent GB-666265-A (GB)
Title: Improvements in or relating to alloy steel
IPC: C22C38/44
Filed: 1949-02-28
Abstract: An alloy steel of controllable hardenability, which has been heat treated to produce graphitic carbon with spheroidization of the residual carbides, has the followin composition:- C 1.0-2.0 per cent, Cr 0.25-1.0 per cent, Mn 0.5-1.5 per cent, Mo 0.2-1.0 per cent, Ni 0.25-1.4 per cent, Si 0.75-2.0 per cent, Fe, and impurities, the remainder.  The graphitization and hardening treatment may comprise the following steps: Ingots are hot worked at not over 2,000 DEG F and may then be forged at between 1,750 DEG F and 2,000 DEG F.  They are then normalized at above the critical range, e.g., about 1,700 DEG F to cause decomposition of carbides.  After cooling they are annealed by heating into or above the critical range, e.g., at 1,450 DEG F for four hours, cooled slowly, e.g., at about 20 DEG F per hour to below the critical range and then air cooled.  Articles are then machined to shape and hardened.  An austenitic-martensitic structure may be produced by double heat treatment.  Thus for articles about 2 inches thick, treatment at 1,625 DEG F followed by cooling in air and reheating at 1,550 DEG F is sufficient, correspondingly higher temperatures being used for thicker sections.

Abstract: 1,088,873. Measuring weight, electrically. WAYNE KERR LABORATORIES Ltd. and R. CALVERT. May 9, 1966 [Feb.8, 1965], No. 5410/65. Heading G1N. A weighing apparatus comprises a load platform supported resiliently at a plurality of points on capacitive load cells (Fig. 2) each connected in the feedback circuit of an A. C. energized amplifier, Fig. 5 (not shown) whereby the output voltage of each amplifier is directly proportional to the displacement of the electrodes of its associated capacitive load cell and hence to the load thereon, the voltage across a load cell being indirectly proportional to the electrode spacing. The amplifier output voltages are summed to provide a measure of the total load on the platform. Each load cell comprises a resilient proving ring 11 (Fig. 2) on a base 13 and having a domed top 14 on which the platform rests, a circular disc electrode 16 electrically and mechanically joined to the ring by a support 15, and conveniently at earth potential. Co-operating with electrode 16 is a circular disc electrode 17 surrounded by a guard ring or neutral electrode 18, electrodes 17, 18 being supported on a stationary coaxial connector having an inner conductor 19 connected to electrode 17 and an outer conductor 20 connected to the guard ring electrode 18. The connector is electrically connected by a coaxial cable 21 to the input of an associated amplifier. The electrodes 16, 17 are arranged so that they remain spaced apart under maximum deflection of the proving ring under load. Stops are provided (not shown) to prevent the electrodes contacting one another if the platform is overloaded. In an alternative embodiment Fig. 4 (not shown) the platform is supported at each corner on the top of a block (21) carried by a pair of leaf springs (22) (23), the undersurface of each block constituting a movable electrode of a capacitive transducer similar to that in Fig. 2. Spaced separated load carriers may be used, for example when measuring the weight of a wheeled vehicle.
