Title: Automatic adjuster for friction devices
IPC: F16D65/54
Filed: 1957-02-12
Abstract: 823,620. Adjusting brakes. BENDIX AVIATION CORPORATION. Feb. 12, 1957 [Feb. 20, 1956], No. 4811/57. Class 103 (1). A device for the automatic adjustment of friction elements in brakes, as shown applied to an internal shoe-drum brake in Fig. 1, comprises a pilot member 38, carried by the friction element, and, in this case, secured to the web 30 of the shoe, a feeler-gauge plunger 51, adapted to engage a stop 64, passing through the pilot member 38 and being gripped by a plurality of inclined fingers or detents 50 on the member 38 so as to provide for relative movement between the pilot member and the plunger in one direction only. As shown in Fig. 2, the plunger 51 moves with the shoe friction lining member 28 so as to engage the brake drum, and as the lining 28 wears away, the plunger is forced back by the drum through the pilot member 38, the lips 46 gripping the smooth cylindrical surface of the plunger 51. The position of the plunger 51, relative to the member 38, is thus adjusted, the release position of the shoe being determined by the abutment of plunger end 51 on stop 64 which is eccentric and may be adjusted by applying a suitable tool to the squared end 68. In Fig. 8, it is carried in the arms of the member 38e, which is U-shaped.

Abstract: 489,447. Printing-surfaces. WIENEKE, H. Feb. 17, 1937, No. 4831. Convention date, Feb. 17, 1936. [Class 100 (ii)] Drawings engraved in intaglio on a surface are reproduced by applying a tanning powder to the lines of the engraving, pressing the treated surface on to a moistened colloid layer so that a tanned image is produced thereon, and printing from the colloid in the usual manner. Before applying the powder the engraved lines may be provided with an adhesive such as a fatty ink. The powder is obtained by mixing a tanning solution with a filler such as bole, kaolin or kieselguhr, and drying and powdering. A suitable powder is prepared from 20 parts by weight of chrome alum dissolved in water and 100 parts by weight of the filler.

Fig. 5 shows a plan of a balance beam carrying wheels 1, 2 the axles of which have extensions 8, 9 connected by a ball joint 13 to the fuselage, an additional strut 7 being provided and ball jointed at 14, 15 to the member 8 and to the fuselage. A vertical spring strut 4 is ball jointed to the centre of the balance beam. Inclined springs on opposite sides of the strut 4 may be provided to keep the balance beam in a, horizontal position during flight. A modification is described in which the members 8, 9 are replaced by a plate secured to the side of the balance beam. Instead of a strut 7 two symmetrically arranged tension members may be used.

Title: Brake control means

IPC: B60L3/10
Filed: 1959-02-17
Abstract: 880,767. Automatic deceleration control systems. LUCAS (INDUSTRIES) Ltd., JOSEPH. Feb. 4, 1960 [Feb. 17, 1959], No. 5439/59. Class 38 (4). [Also in Groups XXXIV and XL (c)] In apparatus for releasing the brakes of a vehicle when the wheels lock, the output of an A.C. generator coupled to the wheels is converted to a D.C. voltage proportional to the velocity of rotation, this voltage is then differentiated and if the rate of change exceeds a certain value a relay is operated to release the brakes of the vehicle. In the Figure the A.C. generator output is applied to terminals t. Transistor T1 and its associated circuit convert the generator output to a square wave of constant amplitude and frequency proportional to the velocity of rotation of the wheel and diodes D2 and D3 convert this signal into a direct current input to transistor T2 the current being proportional to the angular velocity of the wheel. T2 converts this current to a proportional voltage developed across R6. This voltage is differentiated in C5 and R7 and R8 and applied to the base of transistor T3. When the differentiated voltage is of sufficient magnitude to overcome the bias on the base of T3, T3 is switched on. The switching voltage is amplified in T4, T5 and T6 and operates the relay in the collector circuit of T6 to release the brakes. C6 is included in the circuit to delay the release of the relay so that the brakes will not be re-applied until the wheels have had time to return to a normal rolling condition. A stable supply voltage to the equipment is ensured by the provision of the resistor r and diodes d across the power supply as shown. Specification 880,766 is referred to.
