Abstract: 1413881 Monitoring pistons MASCHINENFABRIK AUGSBURG-NURNBERG AG 18 Jan 1973 [22 Jan 1972] 2719/73 Heading G1N [Also in Division H4] The condition of a piston in a cylinder of e.g. an I. C. engine, is monitored by measurement of the vibrations produced in the cylinder lining. As shown (Fig. 1), the amplitude of the longitudinal vibrations of a cylinder lining 1 with reciprocating movement of the piston 2 are measured by transducer 3, rectified at 5 and integrated over one cycle of operation, as sensed by a pulse generator 11 supplying one pulse per revolution of the engine. The signal is held in a sample and hold circuit 9 and compared at 13 with a pre-set maximum value at 12, excess vibration energizing an alarm 14. For a multi-cylinder engine, the signals from each sample and hold circuit 9a-9b (Fig. 2) are individually compared at 17 with the average value obtained at 15, as increased by a set value at 19, to energize an alarm 20. The individual vibration signals are also compared at 21 with a limiting value at 22 to produce a fault signal which is fed to a gate 23 together with the alarm signal from comparator 17 and a critical engine load signal from fuel charge linkage 24. The presence of all three input signals causes gate 23 to com-  mand cut-off of the fuel supply to the engine. The individual vibration signals are also compared at 26 with the average from unit 15, suitably reduced, to ensure that no vibration transducer has failed

Title: Improvements in statistical record card sensing devices
Filed: 1954-01-29
Abstract: 747,441. Statistical apparatus. BURROUGHS CORPORATION. Jan. 29, 1954 [April 8, 1953], No. 2773/54. Class 106 (1). A sensing mechanism comprises a movable contact member associated with a sensing member which is arranged to ride over the surface of the card and to be displaced by a perforation so as to displace the contact member from an inactive position to an active position in which position it is retained until reset to its inactive position. The sensing device is shown in Fig. 1 and comprises a roller 4 mounted between arms 5 integral with a member 3 pivoted at 2 on the arm 1. A spring 6 urges the member 3' anticlockwise about the pivot 2 so that the upturned portion 7 bears against the arm 1 and the roller 4 bears on the surface of the card C. The arm 1 is spring biased by an " over the centre " device comprised by a spring 8 and fixed support 9. When the roller 4 encounters a perforation (or an embossed portion) of the card C, the roller drops into the hole rotating the member 3 and arm 1 anticlockwise about the pivot 2 and causing the contacts 12, 13 to be bridged by the movable contact 11 carried on the upper portion of the arm 1. At the same time the " over the centre " device 8 is actuated to retain the arm 1 and its contact 11 in active position while the member 3 returns to its former position as the roller 4 rides on to the card surface again, Fig. 3. Thus the contacts 12, 13 remain bridged by the contact 11 for a period of longer duration than the time taken for the passage of a perforation under the sensing station. A resetting member 14 is provided which is actuated by the machine at a timed point in the machine cycle to bear against any member 1 and rock it, against the action of the " over the centre " device 8, to its former inactive position. A comb 10 is provided to locate the upper portion of each arm 1 accurately, and a second comb 18 is provided to locate the lower portion of each arm 1 (including the roller bearing member 3) accurately. A third comb, not shown, is located between the contacts 11.

[Also in Group XL (b)] In a device for preventing operation of a coke pusher unless the guide is in position at the other side of the oven of the type in which a beam of light passes from a projector on the coke guide to a light receiver such as a photo-cell on the pusher to operate a relay controlling the ram motor, a holding circuit is provided for this relay comprising holding contacts in circuit with the relay coil and with a conductor energized from the receiving side of the battery so that interruption of the light beam will not stop the ram motor once pushing has commenced. As shown, when the guide is in position its flopper plate closes a switch 8. The operator then closes a series switch 9 energizing a lamp 6. If the pusher is in position at the other side of the oven 1 the light beam falls on a detector 10 which energizes a relay 11 from an alternating supply. Relay 11 completes the circuit of a further relay 13 which closes contacts 14 in the circuit of the ram motor. This relay then locks itself over contacts 15 which are in series with a condenser 16 on the guide a conductor wire 2 on which slide shoes 4 and 5 of the guide and pusher respectively and a condenser 7 on the pusher. A switch 18 is provided on the guide which operates signals 20, 21 on the pusher rectifiers 17 and 22 and a choke 19 being provided to enable signals to be D.C. operated.
