Abstract: 1,171,478. Brake apparatus. S. H. BINGHAM. 24 Nov., 1966 [28 July, 1966], No. 52744/66. Heading B7L. [Also in Division F2] In a braking system for a high speed rail vehicle (see Division F2), a longitudinally extending braking plate 14 is mounted between the rails 11 of a track and braking means, mounted on the vehicle utilizing the track, is adapted to exert braking effort against the sides of the braking plate 14. The braking means comprises brake shoes formed by fluid pressure operated pistons 36 carrying brake friction linings 37 which are mounted on a saddle member 16 supported from the vehicle by depending U-shaped members 18. The retarding effect is transmitted to the vehicle by means of a longitudinally extending drag link 31 (Fig. 2) fixed to the saddle and to the vehicle to permit limited movement of the saddle relative to the vehicle. Brake lining material 37 is also placed at the ends of the underface of the base of the saddle 16 such that, should the saddle make contact with the braking plate 14, the shock will be absorbed by the brake lining material. The U-shaped members 18 are provided with rubber shock absorbers 25 at one end and the bases 20 of the U-shaped members extend through rubber bushings 21 mounted in apertures (22) fixed to the vehicle structure. Instead of being applied hydraulically, the brake shoes could be operated by mechanical or electrical means (not shown).

Title: Process for the defluorination of waste gypsum
Inventor: SCHUMANN HORST
IPC: C01F11/46
Filed: 1966-12-06
Abstract: Gypsum from the production of phosporic acid is defluorinated by calcining at 200-400 DEG  C. with silicic acid in a weight ratio of SiO2 : F of at least 2 : 1, in a current of water vapour. A preferred source of silicic acid is that precipitated by the absorption in water of silicon tetrafluoride from waste gases and the silicic acid is preferably added to the raw phosphate, or to the sulphuric acid, prior to the production of the phosphoric acid.  After the above defluorination the gypsum is suitable for the production of sulphuric acid from the sulphur dioxide which, together with cement, may be formed by decomposing the calcium sulphate with aluminium oxide, silicon dioxide and ferric oxide.

Abstract: 1452075 Spray carburetters HONDA GIKEN KOGYO KK 26 Nov 1973 [27 Nov 1972] 54689/73 Heading F1H [Also in Division F2] The damper 8 retarding the closing of a throttle valve 2 Fig. I in an I.C. engine is rendered ineffective when the ignition switch (39), Fig. 3 (not shown) is opened, to enable rapid closing of the throttle valve 2 by the spring 7. The damper 8 (see also Division F2) is actuated by a control lever 3 attached to the throttle valve 2. With the ignition switch in the closed position, an energized solenoid 27 holds a valve element 24, against the bias of a spring 25, in a position (dotted lines) to close a rapid exhaust passage 23 of the damper. The throttle valve closes at a rate determined by the exhaust of air through a constriction 17. When the ignition switch is opened, the solenoid 27 is de-energized and the spring 25 moves the valve element 24 to open the rapid exhaust passage 23 and exhaust the working chamber 13 of the damper. The throttle valve 2 can therefore close rapidly. A further solenoid operated valve element 35 Fig. 2 is provided to ensure that a fuel supply passage 34, to a duct 30 for supplying precombustion chambers, is blocked when the ignition switch is opened. With the ignition switch closed, the energized solenoid 37 holds the valve element 35 in the open position, and a spring 38 biases it into the closed position when the ignition is turned off.
