Title: Improvements in or relating to devices for monitoring industrial installations
IPC: G08B26/00
Filed: 1967-11-01
Abstract: 1,203,804. Electromagnetic switches. COMPAGNIE FRANCAISE D'ETUDES ET DE CONSTRUCTION TECHNIP. 1 Nov., 1967 [3 Nov., 1966], No. 49589/67. Heading H1N. [Also in Division G1] A switch for use in an industrial process monitoring system comprises bars 14-1 to 14-4 and 15-1, 15-2 slidable along their longitudinal axes in slideways (not shown) under the action of associated solenoids 16-1 to 16-4 and 17-1, 17-2 fed by a supply 20. Each bar is provided with brushes 18a, 18b electrically insulated from each other and rubbing against conductors 19a, 19b. Two longitudinal series of insulated contacts such as 14-1a-A, 14-1a-B and 14-1b-A 14-1b-B are provided on each bar, each series being connected either to a brush 18a or a brush 18b. When switches such as 8-2 and 9-1 are closed the solenoids 16-2 and 17-1 are energized causing movement of the bars 14-2 and 15-1. The movement of these bars causes the hooking together of the contacts 14-2a-A with 15-lb-B and 14-2b-A with 15-1a-B thus establishing a connection between the terminals 12-1 and 11-2. On opening the switches, the bars return to their initial position by the action of gravity or return springs (not shown).

Abstract: 1,180,452. Cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. 31 Oct., 1968 [1 Nov., 1967], No. 49655/67. Heading H1A. Apparatus for making a cable having a layer of wires with periodical reversal of lay, includes a stationary lay-plate 6 and oscillating lay plates 7, 8, 9, each with a central aperture for a core 5 of conducting wire or wires, and other apertures for stranding wires 1, 2, 3, 4, which are applied to the core after 9, and secured by a flexible binder 10, which may be a textile cord, applied in an open helix by lapping head 11. The lay-plate 9 oscillates through an angle greater than 720 degrees, e.g. 900 degrees, and the lay is reversed at intervals at least twice the length of lay. The plates 7, 8, 9 oscillate at the same frequency and in phase with each other and the maximum displacement of each plate with respect to the preceding plate, i.e. 6, 7, and 8, respectively, is less than 360 degrees, e.g. 300 degrees. They are preferably driven by belts 15-17 from a layshaft 18, the driving wheels 19-21 having diameters in the ratio 1: 2: 3. A reversible hydraulic motor (33) drives 18. Plate 7 is of aluminium alloy with apertures for wires 1, 2, 3, 4, having polytetrafluoroethylene linings (25) to lessen friction, and is mounted on a tubular rotor (26) also of aluminium alloy, carried in bearings (27) and having toothed wheel (29) for engagement with toothed belt 15. A permanent magnet (30) operates limit switches (31, 32) which initiate reversal of drive. Plates 8 and 9 are similar except that the magnet and limit switches are omitted.

Abstract: 1,058,570. Shearing; forging nuts. F. B. HATEBUR. Dec. 7, 1964 [Dec. 7, 1963], No. 49722/64. Headings B3H and B3W. An automatic hot-press for producing blanks for nuts, includes feed means for supplying bars 21 from a magazine by continuously rotating rollers, passing the bars through a heating chamber 1, 4, and then feeding the bars by intermittently rotating rollers 17, 18 to a reciprocating shear mechanism 22 where pieces are cut off the bar and transferred by a gripping mechanism 37 to the forging dies. In the feed path is a radiation sensitive device 61 which records the passing of the end of a bar and starts a counter 59 which receives a counting impulse each time the shear operates. After a predetermined number of operations have been counted, the counter 59 sends a signal to a valve 56 controlling a fluid cylinder 57 which through a mechanical linkage renders the gripper 37 inoperative. The counter then begins to count up to a second predetermined number of cuts and the cut pieces produced which are cut from the trailing end of one bar and the leading end of the next har are rejected to waste. When the second number is reached a further signal is emitted by the counter which restores the gripper 37 to the operative condition. Shear mechanism.-The leading end of the bar 21 abuts a feed stop (65), Fig. 3 (not shown), and a piece 21a is cut off by a knife 27 mounted on a carrier 25, which is reciprocated by a cam 32 operating a bell-crank 30. Return movement of the shear head may be by a second cam or by resilient means. The cut-off piece is retained in a slot 26 in the shear head by the spring-loaded gripper 37, which is opened automatically at each cycle by a cam 47, or manually by a lever 50. The device 61 may be sensitive to radiation of visible or invisible frequency different from the radiation of the hot bar, or may be sensitive to the radiation from the bar, in which case it may be used to prevent operation in the absence of a bar, of if the bar is too cold. In a modification the device 61 is replaced by a mechanical feeler operating an electric switch.

Title: Heart pacers
IPC: A61N1/365
Filed: 1973-10-26
Abstract: 1408489 Heart pacemakers AMERICAN OPTICAL CORP 26 Oct 1973 [27 Oct 1972] 50015/73 Heading A5R The invention relates to heart pacemakers of the type in which a stimulating pulse is produced if a timing capacitor charges to a given level and in which the capacitor is discharged through a transistor if detection means detect a beat. According to the invention the output circuit of the discharging transistor is connected to the input circuit of a transistor output stage of the detection means by a regenerative resistive feedback path so as to form a monostable circuit. This can ensure complete discharge by a marginal beat and thus avoid mistiming. In addition reflection signals occurring immediately after a true beat are not effective. In the free-running mode of the pacemaker shown a switch S is closed maintaining transistor TC off. Accordingly a capacitor 57 charges through resistor 35 and 37 until it reaches a threshold value whereupon T7 and T8 become conducting to discharge the capacitor and render conducting a transistor T9 which discharges a capacitor 65 through the ventricular electrodes E1, E2. In the demand mode switch S is open. The R wave of a natural beat picked up by electrode El is selected by a frequency selective amplifier T1, T2 and passed through a low pass filtering arrangement to the 'base of transistor T6 so that the capacitor is discharged and a new timing period commenced. A regenerative feedback path through resistor 91 forms T4, T6 into a monostable circuit so that complete discharge of capacitor 57 by marginal waves is ensured and false operation due to reflected pulses avoided. The low pass filter comprises a capacitor 49 and a constant current circuit T3. The amount of charge and discharge of capacitor 49 during each pulse applied to the base of T4 depends upon the frequency of the pusles and if this is above 30KH the amplitude of the pulses is insufficient to make transistor T6 conduct. A transistor T5 is provided to compensate for variations in the emitter-base threshold voltage of transistor T7. In addition a diode 40 ensures that in the free-running mode the discharge of capacitor 57 is less than the discharge which would occur through T6 so that the frequency is somewhat higher. The arrangement also comprises a circuit T10, T14 similar to T6 to T9 for providing atrial stimulation pulses, the output circuit however being somewhat different from that of the ventricular pulse circuit.
