Title: Device for regulating the pressure of brake shoes
IPC: B61H15/00
Filed: 1929-07-19
Abstract: 315,878. Houplain, G. July 20, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Force-transmitting mechanism. -Linkage adapted to be arranged between a brake piston rod and the rigging whereby the displacement of the rod in applying the brakes is substantially constant irrespective of wear of the brake shoes and whereby, apparently the shoes are rapidly brought into contact with the wheels after which the leverage automatically increases, comprises a lever 5 pivoted at 6 near its lower end, to the piston rod p and having a pin-and-slot connection 9, 10 with a lever 11 connected to the brake rigging. When the rod p moves in the direction of the arrow f to apply the brakes the lever 5 swings about a fixed abutment 3 and the force is at first transmitted through the spring 12 which lengthens when the shoes contact with the wheels to permit the engagement of a tooth 14 on the lever 5 with one or other of the teeth 15 on the lever 11 to provide a solid connection for the transmission of the braking force. As the shoes wear the tooth 14 engages a tooth 15 further from the left hand end of the lever 11.

IPC: C10C1/04
Filed: 1926-09-15
Abstract: 269,052. Schmalenbach. A. June 9, 1926, [Convention date]. Addition to 244,736. Hydrocarbons, distilling.-In the distillation process described in the parent Specification in, which a higher degree of vacuum is used in a still than is used in the column in which the condensate from the still is rectified, the still is operated under the same degree of vacuum as is used in the column, and the effect of a reduction of pressure is obtained by the passage of direct steam through the still. In separating benzol from washing oil, the oil passing through a preheater a enters a vapour-separating chamber b from which vapours pass to a rectifying column c and liquid passes into a distilling-column e heated by injection of steam. The vapours from this column pass into a condenser g, and condensate runs into a separating-vessel h, from which the lower layer of water is run off, and the upper layer, consisting of benzol containing washing oil, is passed into the heated base of the rectifying column c. The condenser f for the vapours from the rectifying-column and the separating-chamber h are connected to a vacuum pump k.
