Title: Remote control system
IPC: B61L3/12
Filed: 1967-09-04
Abstract: 1,142,790. Remote control systems. GENERAL SIGNAL CORP. 4 Sept., 1967 [20 Sept., 1966], No. 40250/67. Heading G4H. Apparatus for remotely controlling a device, e.g. a locomotive includes a transmitter (Fig. 1A, not shown) which transmits a composite signal containing address and command instructions and a receiver (Fig. 1C) on the device which includes circuitry for determining whether the composite signal is correct, a first timing circuit in a command logic module 28 which if the address signal is correct but not the command signal gives an enabling signal after a time delay to a gate circuit 18 which enables a further gate circuit 22 to pass new command signals which if they are still incorrect result in an emergency stop of the system and a second timing circuit 26 connected to the gating circuit 18 which if improper address signals are transmitted for a predetermined time interval also results in an emergency stop. Preferably a radio carrier frequency wave is frequency modulated by the address and command instruction each digit of which is represented by one frequency and non- transmission of this digit is represented by a second frequency. In the embodiment described in which at the transmitter the address and command are entered by push-buttons on a control box (2, Fig. 1A, not shown) outputs from the control box are fed to an address code plug (8) and. address tone generator (9) and to a command tone generator (5) via a dead-man control (3) and diode matrix (4). The outputs of the tone generators (5, 9) are fed to a radio transmitter (7) to which is also fed the output of a randem pulse generator (10). At the receiver (Fig. 1C) the output of a radio receiver 13 is fed to address tone filters 15 and command tone filters 19 an address tone detector 17 giving a positive output signal if the incoming address signal represents that set up on address code board 16. The output of command tone filters 19 is fed via a command tone detector 20 which includes thermistors to provide thermal compensation to the transistorized logic module 28 which determines whether for each possible digit only one of two frequencies have been received. If an incorrect signal is received the output from the logic module is held at - 20 volts and consequently the AND gate 18 is held closed. If correct command signals are then not received for 1.5 seconds a relay is deenergized to open a switch in the output line from command logic module 28 so that the negative voltage is removed and AND gate 18 is opened to enable an AND relay 22 to pass the command signals. If they are still incorrect the application relay logic will result in an immediate emergency stop. The second timing circuit 26 is such that if the output of AND gate 18 does not become positive during an interval of 5 seconds pulse-on pulse-off relays will move the command relays 24 to an emergency stop position.

Filed: 1959-11-27
Abstract: 924,164. Digital electric-calculating apparatus. ELEKTRONISCHE RECHENMASCHINEN-WISSENSCHAFTLICHER INDUSTRIEBETRIEB - KARL - MARX - STADT VEB. Nov. 27, 1959, No. 40441/59. Class 106 (1). In a serial calculating-apparatus performing addition and subtraction on binary-coded decimal numbers but using an adder-subtractor of pure binary type a test is made for ambiguity and correction made where necessary. Each group of four binary digits can represent a decimal digit in known pure-binary manner or a pseudo-decimal digit. Correction occurs at detection of a pseudo-decimal digit, i.e. a code representing numbers 10-15, or when carry takes place to the next denomination. A number taken from a cyclic store 2 is added to or subtract ed from a number taken from another cyclic store 1 in a unit 3 operating in pure binary serial manner. The output is fed to a shift register 7 and also to a further pure binary serial unit 8 in which it is added to or subtracted from an input of 0110, the result being fed to a further shift register 12. A control circuit 13 checks for the presence of a pseudo-decimal number or a carry in the shift register 7 and controls selector 14 to pass the corrected or the uncorrected result, as the case may be, back to the store 1. Entry to the store is adjusted for the delay in the shift registers. Modification, Fig. 5. The output of unit 3 is fed to shift register 7 and then in parallel to unit 8 and selector 14 which also receives the output of unit 8. A correction decider 73 interprets the result in shift register 7 to decide which result shall be sent on by selector 14.

Title: Multi-circuit protective valve assembly
IPC: B60T11/32
Filed: 1972-09-01
Abstract: 1387892 Multi-circuit protective valves ROBERT BOSCH GmbH and DAIMLERBENZ AG 1 Sept 1972 [1 Sept 1971] 40529/72 Heading F2F A multi-circuit protective valve, for a brake system having at least two service brake lines, comprises a plurality of valves each having a spring biased closure member 7, 7<1>, 22, 22<1> operable for air flow at a predetermined pressure, a throttle upstream of each valve at least one of the throttles 30, 30<1> being formed by an extension of the closure member, adapted to enter a valve bore and shaped so that there is a larger flow-through cross-section when the valve is open than when closed. A four-circuit protective valve controls two service brake lines I and II through reservoirs 55, 56 to the rear and front wheels respectively of a long or heavy vehicle, a spring-loaded brake cylinder and trailer supply brake line III through a check valve 60, a hand-brake relay valve 62 to brake cylinders 64 with a mechanical releasing device 63 and a three-circuit controlled, two line trailer brake valve 65 for two coupling leads 67, 68, and a line IV to brakes for secondary loads, e.g. a tipping device, shock absorber &c. Compressed air is supplied from an engine driven compressor 51 to an inlet passage 2 through throttles 5, 5<1> to annular chambers 6, 6<1> to lift the valve closure members 7, 7<1>, to allow air flow to lines I, II. Check valves 15, 15<1> are then opened to allow air flow to throttles 30, 30<1> formed by concave profile conical extensions 27, 27<1> of closure members 22, 22<1> moving in bores 26, 26. Upon lifting of the members 22, 22<1> air flows to lines III, IV. Priority is given to the service lines I, II. Upon failure of one of the lines I, II the associated closure member drops and the associated check valve closes so that air for lines III, IV passes solely through the other valve. For failure of either of lines III, IV, the associated closure member drops. When the brake lines are filled, and when air is tapped from either of lines III, IV, short flow times are obtained for flow from reservoirs 55, 56 to lines III, IV due to the large through-flow cross-section of the respective throttle 30, 30<1>. Upon failure of one of these lines, fluid flow to the defective line is minimized by the small through-flow cross-section. In an alternative embodiment, the conical extensions are used in conjunction with the valves for lines I, II; lines III, IV are supplied directly from the inlet and the check valves 15, 15<1> are absent. A further throttle for each valve for lines I, II, III, IV is provided downstream of the valves, of smaller crosssection than that of the associated upstream throttle when the valve member is raised. In this manner, the pressure is prevented from rapid decrease due to tapping of the line and the upstream throttle is prevented from becoming operative.

Abstract: 1,155,392. Valves. ENERGIEPROJEKTIERUNG VEB. 13 Sept., 1966, No. 40889/66. Heading F2V. [Also in Division F1] A control means e.g. for a water turbine bypass, has a solid needle-type closure-member 3 which coacts with a nozzle 1 at one end of a bent pipe 2, the member 3 being attached to a piston 4 with its under side permanently open to the high-pressure fluid in pipe 2. A manuallyactuated valve 6 controls the connection of the space above the piston to either the highpressure fluid or to exhaust. The area of the upper surface of piston 4 is greater than that of the sealing surface of the member 3. The opening and closing speeds of the member 3 can be set by throttles 15, 16 incorporated in the valve 6 and by the piston itself acting as a valve. The member 3 can be held in the closed position by a threaded stem 20 coacting with the piston 4. The latter arrangement may be dispensed with. In another form, the valve 6 is replaced by a spring or weight-closed double-beat valve which may be operated manually or by a piston- and-cylinder device, the cylinder being movable and connected to the valve via the manual operating means. The piston is attached to the turbine regulating rods and is provided with an oil-overflow valve; the two sides of the piston are in fluid communication through a throttle. The high-pressure fluid has a permanent path to the upper side of the piston via a throttle.

Each pneumatic spring bellows 9, 11 of a motor vehicle suspension system communicates, through a pipe 18, with a chamber 17 the volume of which is variable by movement of a piston 15 to adjust the periodicity of the spring. Preferably each spring bellows also communicates, through a pipe 22, with a chamber 23 the volume of which may be reduced to oppose lateral canting of the vehicle. The rear axle 2 and independently sprung front wheels 5 are mounted on longitudinal arms 10, 12 and connected to levelling valves 34, 40 which control the supply of compressed air from tank 30 to the spring bellows, and to variablecharacteristic dampers 20 responsive through lines 19 to the pressure in the adjacent spring bellows. The position of each piston 15 is controlled by a hand-operated distributor 45 which selectively connects cylinder chamber 16 to an hydraulic tank 42 or to a supply line 43 from engine-driven pump 41. The volume of each chamber 23 is controlled by a piston 26 which may be similar to piston 15 or may be pivoted to an hydraulic jack 52, 53 connected by a line 49 to a distributor 47 containing a transverse electromagnetically-operated spring- centralized valve slide (85) (Fig. 5, not shown) which in its neutral position connects hydraulic pressure line 46 and the lines 49 through line 48 to tank 42. When the vehicle corners pendulum-operated mercury switch 99 actuates one of the electromagnets of each distributor 47 to move the valve slides (85) and connect the pressure lines 46 to the lines 49 on the outside of the curve and hence reduce the volumes of the corresponding chambers 23 and springs to resist vehicle roll.

Title: Information processing

Filed: 1964-10-08
Abstract: 1,087,265. Digital electric data processor WESTERN ELECTRIC CO. Inc. Oct. 8, 1964 [Oct. 9, 1963], No. 41026/64. Heading G4A. Digital electric data processing apparatus including a re-entrant shift register is arranged to automatically perform the following sequence of operations; store signals representing data in one binary form in the shift register; successively for each binary " in in the portion of the binary representation which is converted, mask the binary " 1 " to zero, rotate the contents of the shift register at least two times to bring selected digit positions to the least significant position in the register, and add a binary " 1 " into said least significant positions so as to convert the selected portion into the desired binary code. As described a binary decimal number 53, 0101 0011 is converted to the pure binary number 00110101. For each " 1 " in the tens part of the binary decimal number then 8 and 2, 16 and 4, 32 and 8 or 64 and 16 are added to the ones or binary part of the number. To do this a number 4 equal to the number of digits in the tens portion of the number is entered into a counter. The number is rotated 3 positions to the right to bring the digit representing 2<SP>3</SP> to the least significant digit position 0110 1010. The least significant digit in the tens part of the number is a " 1 " in the second least significant position. The digit in this position is tested to see if it is " 1". If it is zero the number is shifted right one position, the number in the counter is decreased by one and the new digit in the 2nd least significant place is tested to see if it is " 1." If it is one, as in the example, it is masked to produce 0110 1000 and a " 1 " is added in the least significant position to give 0110 1001 and, in effect, add 8 to the original number. The number is then shifted two places left to give 1010 0101 and a further " 1 " added to give 1010 0110. The number is shifted three places right to give 1101 0100, the number in the counter decreased by 1 and the process repeated from the operation testing the 2nd least significant digit. In the example this is zero so the number is shifted: right one place 01101010, the number in the counter decreased to 2 and the 2nd least significant digit is tested. This is now " 1 " so it is masked and a " 1 " added to give 01101001. It is shifted two places left and a further " 1 " is added, 10100110. It is shifted right three positions, 11010100, and the number in the counter reduced to 1. The 2nd least significant digit is tested, is 0, so the number is shifted right one position 01101010, and the number in the counter is now zero. The iteration is now complete and the programme loops completed. A further instruction causes a right shift of one position to give 00110101 as required.
