Filed: 1973-12-07
Abstract: 1448127 Automatic sound producer ROBERT BOSCH GmbH 7 Dec 1973 [14 Dec 1972] 56759/73 Heading G5J A switch system for use with two horns, as on fire engines &c., which upon depression of the alarm switch 10 are sounded alternately for four substantially equal time intervals comprises two relays 14, 15 energizing horns 16, 17 respectively in response to switching of an astable multivibrator 13 and a monostable multivibrator which enables the astable only long enough for two cycles to take place. The switch 10 actuates a one-shot 38, 39 and this provides power via line 57 to a multivibrator 50, 51 which initially has 50 ON and 51 OFF allowing relay 15 to operate via the contact 14b, thus turning horn 17 ON. Relay 15 also directly grounds line 57, previously held near ground when the one-shot operated. After the preset time the multivibrator changes state, 51 is ON and 50 OFF, and relay 14 operates, disconnecting relay 15 which releases. The one-shot is still ON maintaining the power supply, but relay 14 operates turning on horn 16 and grounding line 57 before relay 15 releases. The cycle repeats, the multivibrator switches over, relay 14 releases, relay 15 again operates to ground line 57 and horn 17 is turned on again. This time the one-shot being ON is the sole feature continuing the process till relay 15 has operated. The one-shot preset period now ends. Relay 15 still provides power to the multivibrator which changes state at the end of the 3rd period, operating relay 14 which via 14c continues the power supply to the multivibrator and then turns off relay 15 and sounding horn 16. Finally at the end of the 4th period, relay 14 releases and the power supply to the multivibrator is broken at 14c preventing any further tones from being sounded.

Title: Data communication system employing a series loop
IPC: H04B3/00
Filed: 1973-12-11
Abstract: 1451367 Automatic control JOHNSON SERVICE CO 11 Dec 1973 [15 Dec 1972] 57315/73 Heading G3N [Also in Division G4]  A data communication loop system comprises a plurality of remote stations coupled to a loop controller by a serial transmission means; each remote station receives a continuous series of time-spaced data frames and transmits said frames to a succeeding station and responds to certain frames in accordance with data contained therein. As shown, Fig. 1, a central computer centre 1 includes a computer unit 2 which is connected in a time-sharing mode to remote loop systems 3-5. A loop system such as 3, includes a loop-controller 7, comprising a stored programme computer 7a, which generates message frames 11,12 which are transmitted, over a cable 10, in serial fashion around a loop formed by remote stations 8, 9. The remote station 9 is an operator's console, which is portable and can be connected into the loop to permit manual introduction and removal of information and selective monitoring of the remote stations 8. A remote station 8, Fig. 2, provides for the control of a plurality of load devices, such as a contact sensor 21, a controller 22 and on-off switching of a motor 23, through the interface of point modules 16-18, and a teleprinter 16b through a special point module 16a. The data-frames are handled by a logic unit 13 which is associated with a frame-generator 27 incorporating a timer 28, which is responsive to an open-loop condition on the input to signal a fault condition to the loop controller. A power supply and monitoring system 24 senses failure of a non-essential voltage and causes a message frame to be set up to inform the loop controller accordingly. The sensing of the failure of an essential voltage causes the automatic actuation of a switch 25 taking the remote station out of the loop. This isolation is noticed by the loop controller when the remote station fails to respond to a dedicated message. Each message frame comprises four bytes each of eight bits plus a parity bit. The first byte identifies the frame type as (a) a "Null" frame to which no response is expected, (b) a "Dedicated" frame which is assigned to a particular remote station and a particular point-module therein and (c) an "available" frame which is used by the first remote station that wishes to communicate with the loop controller. The second byte provides an acknowledgement of the status of a message frame, and the address of any point module associated with a remote station. The third byte includes a plurality of command bits for the addressed point module and status bits. The final byte supplies data to a particular point-module load and receives information therefrom in accordance with the command. The frame generator 27 monitors the time delay between message frames and generates fault frames containing its own address if an interrupt occurs. Each loop system may be provided with a battery-powered real-time clock for continuing operation of the system in the event of a power failure.

Abstract: 636,477. Counting-apparatus ; totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Feb. 28, 1947, No. 2968. [Class 106 (i)] [Also in Group XXIV] A displaying device particularly applicable to totalizators comprises a rotatable member, a rotatable indicator co-axial with said member and interconnecting means between said member and said indicator whereby on movement of the rotatable member from one stationary position to another relative movement between the rotatable member and the Indicator may take place and if so the indicator will always be brought back to its initial position relative to the rotatable member. The rotatable shaft 1, Fig. 1, carries a heart-shaped cam 2 which co-operates with a roller 5 carried by a lever 4 pivoted on an indicator disc 3 rotatable on the shaft. A spring 6 constantly urges the roller 5 against the cam and the arrangement is such that if the cam is rotated with rapid acceleration, then stopped, the spring 6 will pull the roller 5 to the root 7 of the cam 2, thereby rotating the indicator disc 3 to a position indicative of the angular position of the shaft. If the cam is rotated with no acceleration the disc 3 moves with it.
Patent GB-666502-A (GB)
Abstract: 666,502. Automatic temperature control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 20, 1948 [Dec. 20, 1947], No. 32867/48. Class 38 (iv). In apparatus for controlling the temperature of an electric blanket or the like, the heating winding 2 has a high temperature coefficient of resistance and is corrected in series with a low resistance 9 and a large resistance 8 acting as a current limiter for the heater when the temperature exceeds a predetermined value. The resistance 8 is short-circuited during heating periods by means of a relay 12 controlled by the anode current of a thyrator 11, to the control grid of which is fed a control voltage dependent on the resistance of the heater 2. When the heater is initially energized the voltage across the resistance 9 is fed via the primary of a transformer 26 and potentiometer 30 to the grid of the thyratron 11, thereby causing the valve to conduct, energizing the relay 12 and short-circuiting the resistance 8. Full current then flows through the heater 2 until at a predetermined temperature the resistance of the heater 2 has so increased that the voltage across the resistance 9 is no longer sufficient to maintain the thyratron conducting. The relay 12 is then de-energized placing the resistance 8 in series with the heater, thereby limiting the current flow through the heater 2. De-energization of relay 12 also places a second primary 28 of the transformer 26 and the secondary 17 of a mains transformer 15 in series across the heater 2. The windings 17 and 28 are so connected that the voltage of the secondary 17 is greater than the voltage across primary 28 when the resistance of the heater is high. and the thyratron is maintained non- conducting. As the heater cools, however, the voltage across primary 28 increases until the resultant voltage applied to the grid of the thyratron is sufficient to cause it to conduct, whereupon the heater is again fully energized. In a modification, Fig. 3 (not shown), the thyratron may be replaced by a " hard " double triode, the cathode of one section being under the control of a second temperature variable resistance responsive to ambient temperatures. The relay may include additional contacts for disconnecting the primary 27 during cooling periods to achieve a closer control.
