Abstract: 444,955. Fluid - pressure brakes. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H., Titanic Works, Lincoln. Aug. 29, 1934, No. 24935. [Class 103 (i)] [See also Group XXIX] In a hydraulic brake system comprising a common master cylinder for operating both front and rear vehicle brakes, a device is inserted in the conduit leading to the rear brakes for limiting the pressure therein. The device may comprise a casing 3, Fig. 1, with an inlet 4 and outlet 12 and containing a piston 1 which when the fluid pressure is sufficient to overcome a spring 5 seats a valve 9 carried by the piston. According to Fig. 2, the device comprises a pair of pistons 18, 19 of unequal diameter connected by a rod 20. carrying a valve 22 and having a through passage 21. Liquid supplied by the master cylinder enters at 14 and passes through the piston chamber 16, the passage 21, piston chamber 17 to the outlet 15 and when the pressure difference acting on the pistons is sufficient to overcome the spring 23 abutting on an adjustable collar 25 on the rod 20 and on the casing, the valve 22 is closed. By removing the end plate 28, the pistons and spring can be removed from the casing. The casing has a removable plate 27 to permit of access to the collar 25. A renewable seat 29 for the valve 22 is provided.

Title: A synchronized change gear indicator
IPC: F16H59/44
Filed: 1919-10-13
Abstract: 158,935. Chinn, W. Oct. 13, 1919. Variable-speed gearing suitable for motor vehicles is provided with means for indicating the relative speeds of the teeth of different gears so as to facilitate changing speed. A " master " pointer h is driven through a governor c and flexible shaft i from the driven or tail shaft o<1> of the change-speed gear. Other pointers s, w, z geared together and turning about the same axis as the pointer h are driven through a governor c<1> and flexible-shaft h from the driving-shaft. The positions of the pointers s, w, z indicate respectively the speeds of the teeth of a clutch o, Fig. 3, and of countershaft gears p', p<2>. In Fig. 8 is shown the indication at the top speed. If this speed is disconnected, and the car slows down, the pointer h turns to the left, passing over the others. When the pointer h coincides with the pointer w as shown in Fig. 6, it means that the corresponding speed may be engaged without shock. If the engine varies in speed, the pointers s, w, z open out or close in so as to indicate on the inner scale shown the speeds of the corresponding gear. The position of the pointer h on the outer scale gives the speed of the car absolutely in miles per hour. Reference has been directed by the Comptroller to Specifications 8065/07, 22312/13, 5843/14, and 107,102.

Title: Improvements in two-way transmission systems with repeaters, particularly for telephone lines
IPC: H04B3/20
Filed: 1924-10-21
Abstract: 246,544. Western Electric Co., Ltd., [Western Electric Co., Inc.]. Oct. 21, 1924. Two-way repeating systems. -A repeat,er unit interposed in a two-wire line includes echo-suppressing circuits by which the return path is opened or short-circuited, so arranged that the echo-suppressor controlling the path in use cannot be operated by leakage of current through the hybrid transformer. Fig. 1 shows an arrangement with amplifiers 7, 8 and a single relay 13 adpted to short-circuit either path through a transformer, the windings being connected as shown through rectifiers 21 - - 24. For transmission East, for example, rectifiers 21, 24 receive current, and the corresponding windings of relay 13 move its armature against contact 26 to short-circuit the westward path. Either pair of rectifiers 21, 23 or 22, 24 may be omitted. In a modified arrangement, the single relay 13 is replaced by a pair of relays, one associated with each path. The windings connected to rectifiers 21, 24 then serve to hold the relay against possible operation by currents through the other windings. A delay circuit is inserted in each path. Fig. 2 shows an arrangement employing two controlling relays 33, 34 connected to rectifiers 32, 35. For transmission east, relay 33 operates to hold the eastward path closed, while relay 34 operates to open the westward path. A further relay 45 energizes and removes a shunt from the path in use. Delay circuits 30, 31, and, if desired, one-way valves 40, 41 are inserted in the two paths. Relays 36, 38 controlled by the relays 33, 34 serve to delay the removal of the short-circuit across the return path. In certain cases, the rectifiers and controlling relays may be replaced by A.C. relays. Modifications of this arrangement are described.

Switches, actuating. - A tumbler or other switch D mounted with the tumbler lever askew on the frame of a door within a room to control the lights therein is operated by the engagement therewith of a flap B<1> mounted to fold in one way only on a lever B pivoted within a casing secured to the door. On entering the room and closing the door, the switch may be moved by hand to the " on " position shown in dotted lines. When the door is opened the flap rides idly over the tumbler knob, but when the door is closed again the flap drives the tumbler to the " off " position. In order to allow of the door being closed again without switching off the light, the lever B may be lifted about its pivot a and moved sidewise slightly so that it is retained by a ledge of the slot a<2>, Fig,. 2, in the casing through which it passes, against the returning action of springs. In this position the lever does not engage the tumbler in closing the door, but in the finally closing movement a cam projection E on the frame releases the lever B so that when the door is again opened and closed the switch will be opened.
