Title: Disc brake
IPC: F16D55/22
Filed: 1957-03-12
Abstract: 830,236. Disc brakes. BENDIX AVIATION CORPORATION. March 12, 1957 [March 17,1956], No. 8156/57. Class 103 (1). In order to avoid friction pads of a spot-type disc brake tilting in their bores due to unequal wear of the friction surfaces of the pads, the application force on a friction pad is provided at a point to compensate for the effect of differences of linear velocity to which the surface area of the pad is subjected and to compensate for the tilting torque due to the reaction generated by friction of the pad on the surface of the rotor and the wall of the bore recess. In the disc brake illustrated in Figs. 1 and 2 in which an axially slidable disc 2 is rotatable with shaft 4 and is adapted to be braked by friction pads 10, 8 housed in a stator housing 6 such that actuation of hydraulic piston and cylinder mechanism 14, 16 urges friction pad 10 into frictional contact with a side of the disc 2 which is then moved into frictional contact with the fixed pad 8. In accordance with the invention, the axis Q of the piston 16 does not coincide with the centre e of the pad 10 but is displaced by a radial distance x from the centre e of the pad 10 and a distance y in the direction of rotation of the disc. The distance x is calculated to compensate for the difference in linear velocity and the distance y is calculated to compensate for the tilting torque of the reaction generated by the friction of the brake pad on the surface of the disc and the walls of the recess 12. Specifications 688,382 and 783,081 are referred to.

Filed: 1966-02-24
Abstract: 1,139,888. Pyrolytic graphite. SOC. GENERALE DU VIDE "SOGEV". 24 Feb., 1966 [26 Feb., 1965], No. 8275/66. Heading C1A. [Also in Division C7] Anisotropic or orientated material e.g., tungsten, molybdenum, the carbides or nitrides of zirconium, hafnium or tungsten, or preferably pyrolytic graphite, is obtained by the thermal decomposition of a gas or vapour at a heated surface in a reaction chamber by feeding the gas or vapour through an inlet member which defines one wall of the reaction vessel, the member being so constructed that the gas emerges directly into the chamber through a subsidiary gas inlet channel and indirectly into the chamber from a main gas inlet channel through distribution channels with walls so orientated as to provide an even gas flow over the surface of the reaction chamber, the distance from the external surface of the inlet member to the surface where the deposit is formed being substantially equal to the mean free path of the atoms of the material to be deposited under the existing thermodynamic conditions. A suitable apparatus is shown in Figure 3, and comprises a heatable outer vessel, for example, a muffle 12, into which is inserted a member 13 made of refractory material e.g. graphite which with muffle 12 defines a reaction chamber 16. Member 13 preferably comprises two superimposed parts 13a, 13b which contain a central or main gas inlet channel 14 and a subsidiary annular gas inlet channel 15 which opens out directly into the reaction chamber. The main channel 14 may be thermally insulated e.g. by screens 17 and layers of graphite powder 18, and it opens out into lateral distribution channels 19 which communicate with chamber 16. A number of channels 19 may be distributed along the length of the main channel and these channels 19 have walls 20 which are orientated so as to distribute the emerging gas in the reaction chamber. Introduction of a hydrocarbon, e.g., methane, through channels 14 and 15 when the muffle is heated to 2000‹ C., causes a deposit 21 of pyrolytic graphite on the muffle. This graphite is homogeneous in quality and has a density of 2À21g/cc.
