Title: Remote meter reading systems
IPC: H03M1/00
Filed: 1971-10-27
Abstract: 1373918 Photo-electric dial-readers NORTHERN ILLINOIS GAS CO 27 Oct 1971 [1 March 1971] 11732/74 Divided out of 1373916 Heading G1A [Also in Division G4] The disclosures are identical to that of the Parent Specification 1373916 but the claims relate to the combination of a remote meter reading system having encoder means for providing signals indicative of a meter reading to a read-out means, with apparatus for sensing the condition of apparatus at the location of the meter and reading the sensed information out through the same read-out means. Two pieces of gas pipe are electrically insulated from each other and one is earthed. A voltage sensor is connected across the two pipe portions and a switch is not operated if the potential difference between the pipes is less than a certain value, and operated if it is greater. This switch serves to mark or not mark the input line (D4) Fig.8 (not shown) of the "1 out of 10" code circuits and a code word corresponding to digit "0" is read-out from the "2 out of 5" encoder (202) if the line is not marked, and the digit "4" if it is marked. This read-out is effected on use prior to that from the meter.

Title: Improvements in internally expanding brakes
IPC: F16D65/54
Filed: 1940-01-24
Abstract: 536,085. Adjusting brake shoes. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. Jan 24, 1940, No. 11741. Divided out of 524,180. [Class 103 (i)] In an automatic adjusting device for the shoes of internal expanding brakes a pull-off spring 23 is connected to the shoes 9a, 9b by a pair of gripping devices 20a, 20b the movement of which is limited by the co-operation of a slot 20d' in the device with a fixed stop 24a. When the brake is initially applied the inner edge of each slot 20d engages the stop and as wear of the shoe occurs the shoe slips relatively to the gripping device. When the brake is released the shoe returns a constant distance determined by the engagement of the outer edge of the slot with the stop as shown. Each gripping device comprises a pair of plates 20a, 20d urged by. a spring 21 on a pin 22 to grip the shoe web 9c. The stop comprises a flange 24a on a plate 24 fixed to the back plate 18, the flange having a recess to receive the plate 20b. A projection on each flange 24a passes through a slot in the shoe web 9c and spring 25 attached at one end to the projection bears on the web and thus restrains lateral movement of the shoe. The upper ends of the plates 24 serve as stops to limit the outward movement of the pistons of the operating cylinder 7 to prevent the metallic face of the shoes from engaging the drum if the friction linings are allowed to wear away completely.

Title: Improvements in or relating to the automatic control of fluid pressure systems
IPC: F01L13/04
Filed: 1929-04-16
Abstract: 332,541. Heywood, C. F. April 19, 1929. Fluid-actuated valves.-Compressed air is supplied for utilization through a manually controlled outlet from a storage tank supplied by a pump having an automatic relief valve to atmosphere, this relief valve being automatically put out of action so long as air is being supplied from the tank. A valve block is connected at the part j<2> with the outlet of a compressor, and at the part a<1> with the interior of a tank to which the air is supplied through a passage j and valves i<4> and c<2> opening against spring pressure. The outlet from the tank is by ports c<6> controlled by the valve c<2>, and a connection h leading from the space a<3> above a valve b. Should the pressure rise above the limit, a valve k<4> is lifted and allows air to pass to the upper side of a diaphragm m', depressing this diaphragm and a piston p below it, and opening a ball valve s which allows the compressed air in the passage j to escape to atmosphere through a port t. The space above the diaphragm is closed by a valve o<2> held down by a loose spring-pressed piston u enclosed in a sliding cap v. To supply compressed air, e.g., to start an internal combustion. engine, a lever f, f<3> is operated by a Bowden wire g' and initially raises the cap v, weakening. the pressure of the spring on the piston u and allowing the valve o<2> to rise and rent the air in space above the diaphragm to atmosphere around the piston. The piston p is lifted by its spring, and allows the ball valve s to close. The further movement of the lever depresses a stem b<4>, and through it the valves b, c<2>, allowing air from the tank to pass to the space a<3> and the connection h to the engine.
