Title: Improvements in or relating to Hydraulic-Control Brake Systems of Vehicles
IPC: B60T8/18
Filed: 1967-07-07
Abstract: 1,159,879. Tractor trailer braking system. SOC. ANON. ANDRE CITROEN. 7 July, 1967 [18 July, 1966], No. 31453/67. Heading F2F. In a tractor/trailer braking system it is arranged that when a pedal is depressed, firstly pneumatic or vacuum trailer brakes are applied, then the tractor hydraulic rear brakes and then the tractor front brakes. The brake pedal 5 (Fig. 1) controls the front and rear wheel brakes 30, 29 respectively through a distributer valve 33 (see Specification 796,071), in which slide valves 6, 7 control hydraulic circuits 23, 25 respectively the valves 6, 7 being fed with compressed hydraulic fluid via two lines (not shown). The pedal acts through a thrust roller 2 on a rocker 8 bearing on the valves 6, 7. The position of the roller is controlled via a linkage 35 and lever 36 by a device 37, in dependance upon the load on the rear wheels of the tractor. To actuate the rear brakes before the front brakes, irrespective of load, a lost motion is provided between the brake pedal and the roller 2, and the free end of a blade spring 1 secured to the pedal engages the valve 6. Thus when the pedal is depressed the blade 1 will act on valve 6 whereby hydraulic fluid pressure is transmitted via line 23 to the rear brakes 4 before the pedal engages the roller. The rear brakes will be only lightly engaged because of the counter action of springs 3 on the brake shoes. Simultaneously the hydraulic pressure in line 23 is applied to a safety valve 9 (Figs. 1 and 3) moving a slide valve 10 downwards against a spring 13 whereby the pressure will be applied to a piston 15. Movement of piston 15 opens a valve 21 in the pneumatic circuit of the trailer brakes, via levers 16, 17 the ratios of the levers being such as to cause valve 21 to open sufficiently to transmit compressed air, from a reservoir (not shown) on the trailer, to apply the trailer brakes before the tractor brakes are actuated. On failure of feed line 23, fluid in feed line 25 will operate the trailer brakes.

Title: Method of growing a single-crystal
IPC: C30B7/10
Filed: 1972-07-06
Abstract: 1393619 Growing single crystals ORDENA TRUDOVOGO KRASNOGO ZNAMENI INSTITUT KRISTALLOGRAFII AKADEMII NAUK SSSR IMENI AV SHUBNIKOVA 6 July 1972 [7 July 1971] 31568/72 Heading BIG In a method of growing a single crystal from a seed crystal the appearance in the former of defects in the latter is substantially eliminated. The method comprises applying to the seed crystal a coating of a material which is capable of acquiring the growth promoting capability from the seed crystal and contacting the coated seed with the substance to be crystallised. The coating, which must be sufficiently thick to eliminate surface defects of the seed and sufficiently thin to retain at its surface polarization induced from the seed and which is desirably a metal, e.g. An, Ag, Pt, Cu or Ni but may be a dielectric or semiconductor, is deposited on the seed chemically or by thermal evaporation in a vacuum or by cathode sputtering. In an example a hydrosodalite seed crystal was coated with a layer of gold of thickness 500-2,000 by thermal evaporation in a vacuum and placed in an autoclave filled with 30% NaOH solution at 400C. The growth material was a mixture of SLO 2  and Al 2 O 3 . The autoclave temperature was rapidly reduced and growth occurred over 30 days. Examination of the resulting single crystal of hydrosodalite revealed that the gold layer 'had largely prevented seed defects from being transferred to the single crystal. The seed crystal and single crystal grown thereon may be different chemically and structurally. Thus a potassium iodide crystal may be grown on a gold-coated seed of mica. In a further example a single crystal of lead sulphide is grown by exposing a seed crystal of lead sulphide coated with germanium to an atmosphere of sublimed lead sulphide at 1,000C.

Filed: 1921-11-26
Abstract: 187,490. Seely, J. E. B., Seely, F. E., and Farmer, C. D. Nov. 26, 1921. Gyroscopic apparatus.-An instrument for indicating latitude comprises a gyroscope the axis of which is brought into the meridian plane, the latitude being indicated by the torque required to retain the axis horizontal. In the form shown in Fig. 2 the casing c is mounted on horizontal trunnions in the ring a, one of the trunnions being formed with an axial air-passage leading to a box o having two oppositely-disposed nozzles r, r'. The casing carries a U-tube s containing liquid and having open ends t, t<1> each normally covering half of the adjacent nozzle. When the gyro-casing tilts the air-jets become unbalanced and produce a restoring torque about the vertical, the magnitude of which is indicated by the resulting movement of the liquid in the U- tube. The gyroscope is itself north-seeking by reason of friction around the axis EF, but the instrument may be set with its axis on the meridian. Figs. 4 and 5 show an electromagnetic torque-applying device in which the trunnion u carries a. cam w bearing against metal strips x, x<1> secured by way of insulation z, z<1> to carbon blocks 2. 2<a> carried by the ring a.
