Title: Improvements in or relating to a pressure-fluid actuating assembly, particularly forhydraulic braking systems
IPC: B60T11/224
Filed: 1955-06-16
Abstract: 770,837. Hydraulic master cylinders. FAWICK, T. L. June 16, 1955 [June 29, 1954], No. 17388/55. Class 103 (1). In a pressure-fluid actuating assembly, particularly for hydraulic braking systems of vehicles, comprising a single fluid impelling member operating in a chamber, means are provided for varying the mechanical advantage of the manually actuated means such that the mechanical advantage gradually increases substantially throughout the working stroke of the fluid impelling member; yielding means being provided between the manually-actuated means and the fluid impelling member. In the embodiment illustrated, an hydraulic master cylinder unit 10 provided with a single piston 13 operable within a cylinder 12, is provided with an L-shaped foot lever 28 fulcrummed at 29 to a pair of bearing brackets 30, 30 which are secured to the casing of the master cylinder unit 10. The short arm 28a of the foot lever 28 is hinged at 32 to one end of a toggle link 33 pivoted at 34 to a sliding guide member 14 which is slidable in cylinder 12. The stem of piston 13 slides in the hollow sliding guide member 14 to a limited extent providing a lostmotion connection between the two parts and a strong compression spring 22 is interposed between the piston and the large diameter part of the sliding guide member 14 to constantly urge the two parts away from each other. In operation, during the first part of the actuating movement of the brake lever 28 the toggle 28a, 33 is at a position of low mechanical advantage such as to impart rapid motion to guide member 14 and piston 13 for quickly moving the brake shoes into contact with the brake drum. When the shoes contact the drum, the spring 22 is further compressed by movement of the guide member 14 closer to the piston, this action being concurrent with movement of the toggle elements to positions of progressively higher mechanical advantage as the braking pressure increases. A modification is described and illustrated in the Specification wherein the toggle mechanism is replaced by a cam and roller arrangement.

Title: Improvements in or relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1939-06-16
Abstract: 530,451. Automatic exchange systems. ELECTRICAL RESEARCH PRODUCTS, Inc. June 16, 1939, No. 17618. Convention date, June 17, 1938. [Class 40 (iv)] In a system in which connections are set up under the control of common apparatus, the latter at a certain stage tests whether the metering circuit is intact, and if it is not, does not complete the connection. On a call from a flat-rate subscriber who is not provided with a meter, the test is omitted. The invention is described in relation to a cross-bar system of the kind described in Specification 466,986 in which a marker seized by a registercontroller selects an idle junction in the appropriate direction in response to the exchange digits and controls the extension of the calling line thereto at district and office frames each comprising primary and secondary switches. Assuming that the marker has been seized by the register-controller 130 and has been connected to the proper district frame by relays 131, 132, relays 221, 227, 231, 232 are up as well as relay 119 in the district trunk circuit, the latter being held in parallel with 131 under the control of 221. After the selection of an idle junction and an idle channel thereto, relays 222, 223 energize in series with hold magnets 123, 206 respectively and disconnect 227, which feeds ground from wire 255 over wire 145 to operate hold magnets 126, 205, and the latter extend ground over the links 146, 260 to shunt down 222, 223. Relay 228 energizes over the sleeve 257 of the junction, while 218 energizes over sleeve wire 152 and removes direct ground from wire 255, leaving the four hold magnets connected in series with 238 which operates. The relapse of 227 also connects the metering circuit over wire 245 to 220 which operates provided the circuit is intact, disconnects 221, other circuits of which are opened by 218, 238, and connects up 234, thereby dissociating the marker from the district frame and initiating its release. The connection is subsequently completed by switching relay 115 and metering takes place upon release by the application of battery over wire 180. In the case of a two-party-line the appropriate meter is connected up by 114 which is operative under the control of 213,214 when wire 168 is grounded in the register-controller. If 220 fails to operate, 221 is held, and a circuit is made for 224 which sends a trouble signal to the register-controller over wires 273, 161, connects up 229 to initiate release of the marker by the operation of 234 and disconnects 217 to open the circuit of the hold magnets. The register-controller makes three attempts to set up the connection, and if 220 still fails at the third attempt, 274 pulls up and withholds the trouble signal. Switch-through therefore occurs, and the calling line remains locked to the district trunk circuit. It will be noted a subscriber may be denied service merely by disconnection of his meter. In the case of a call from a flat-rate subscriber, 220 is connected up locally by 245<SP>1</SP> which is operated from the register-controller.
