Abstract: 1,122,177. Data stores: feeding record strips. INTERNATIONAL BUSINESS MACHINES CORP. 12 Sept., 1966 [26 Nov., 1965], No. 40612/66. Heading G5R. In a random access memory, a selected one (or ones) of a plurality of record strips is driven into or out of a housing where it is located alongside a circular path along which a transducer is arranged to move. As shown, magnetic record strips are arranged in movable trays adjacent respective entry chutes into a cylindrical chamber 12 in a housing 22. A drum carries three heads such as 25 and associated circuitry 28-30 and rotates with a hollow shaft 23 belt-driven by a motor 43. The strips are arranged in sub-cells of eight and have staggered tabs 1-8 (Fig. 3) at their rear ends engageable by solenoids 49-52 carried by a support 55 which is vertically shifted by a solenoid 54 and which also carries transverse bars 56, 57 arranged to enter notches in alternate strips so that the selected strip does not carry the adjacent strips with it. When a particular track is addressed, the appropriate tray is moved by a solenoid 38 until the sub-cell is opposite an entry shoot whereupon an acuator 20 pushes the strip into engagement with the advance capstan of a counter-rotating pair 21 which drives it along circumferential guides (62), (63), (Fig. 4, not shown) in the chamber 12 until its forward edge engages stops (64). The head element such as 67 (Fig. 5) pertinent to the selected track is energized by a generator 42 coupled to the shaft 23 and suction is switched via channels 71, 69 to slots 68 in advance of the head 67 to draw the strip close to but not touching the head as the latter rotates (e.g., at 1800 r.p.m.). Each head contains 44 elements and each strip 132 tracks so that each track is read by only one head element of the three-head assembly. After reading or recording, the strip is ejected by switching suction to the other of the capstans 21, air being supplied to the tray to lubricate the passage of the strip. Signals to and from the heads are carried by capacitive coupling between concentric rings 32, 34 mounted on rotating and stationary plates 31, 33 respectively.

Abstract: 945,240. Ignition systems, ignition timing. ESSO RESEARCH & ENGINEERING CO. Jan. 22, 1962 [Nov. 8, 1960], No. 41259/59. Heading F1B. The ignition timing is controlled by a contact breaker associated with a time delay circuit. The ignition timing is kept constant at varying engine speeds. As shown a signal which is at the voltage supplied to the contact breaker is applied to a mono-stable blocking oscillator 2 which is conveniently of the transistor type. The output pulse from the blocking oscillator 2 is used to energize a time base circuit such as a Miller Sweep circuit 3 which generates a voltage which rises linearly with respect to time. The circuit 3 is associated with a differential amplifier 8 and amplifier 6 and a bi-stable circuit 4. The bi-stable circuit is also energized by a pulse from the blocking oscillator 2 which causes it to revert to its first stable condition. Pulses are fed from the bi-stable circuit 4 to activate a spark generator ignition unit 7. A feed back loop including the differential amplifies 8 is employed to keep the timing constant for varying engine speeds. An indication of spark advance may be obtained by connecting a moving coil meter to -the bi-stable circuit 4. The component parts of the circuit are described. The use of valves is referred to.

The position of a piston 39 connected e.g. to a three-way valve, is controlled by a solenoidactuated three-way pilot-valve 48 and a lock valve 15. With the latter in its right-hand position and the solenoid 51 energized fluid passes from an inlet 43 to a piston port 35 via lock valve ports 16, 21, pilot valve inlet and outlet 45, 46, lock-valve port 34 and lock-valve chamber 33 so holding the valve 15 in the position shown. If the solenoid 51 is deenergized, e.g. due to a circuit failure, the pilot valve 48 connects the chamber 33 and piston port 35 to an exhaust port 49 so that the piston 39 is spring-returned and the lock-valve 15 is urged by inlet pressure and a spring to the position shown. Upon repair of the circuit failure, the lock-valve 15 must be moved manually to the right before fluid pressure is again available at motor port 35. Similar conditions will apply as the result of reduction or disruption of the fluid-pressure supply and its subsequent restoration. In a modification, the lock-valve comprises two abutting parts, one part controlling the fluid flow to and from the valve actuating piston, and the other part being a manually-operable piston defining the movable portion of the lockvalve chamber. The fluid supply to the valve actuating piston does not pass through the pilot valve.

Filed: 1969-09-02
Abstract: 1285476 Signalling over power lines FRANKLIN ELECTRIC CO Inc 2 Sept 1969 [3 Sept 1968] 43442/69 Heading H4R A transmitter for signalling over power lines comprises a potential breakdown device and a storage device connected in series across the power lines. As the potential across the breakdown device rises during an A.C. supply cycle breakdown occurs allowing the storage device to charge, reducing the potential across the breakdown device to below the extinction potential, and producing a narrow pulse which is transmitted over the lines to a suitable detector. A number of suitable transmitters and receivers are described. Transmitter.-Fig. 2 comprises a circuit using a neon 26 in series with a capacitor 27 connected across power lines via a bimetallic switch 28, actuated, e.g., by the temperature rise in an electric motor winding. The neon may be replaced by a spark gap or a TRIAC which may be biased by a D.C. source or triggered by connecting a neon between the gate and the connection between the TRIAC and the capacitor (Fig. 6, not shown). Alternatively a S.C.R., e.g. 52, Fig. 5, may be used which is triggered when the voltage across a TRIAC 66 reaches the firing potential. Since the S.C.R. will only conduct with one polarity of supply a pair of S.C.R.'s 62, 62a are used back-to-back to provide pulses on both half-cycles. Diodes 67 and 67a are provided across the S.C.R.'s to allow the capacitors to discharge during the inoperative half-cycles. If the diodes are omitted, Fig. 4 (not shown), the pulses will be generated only during the first half-cycle in which the transmitter is connected to the line and not in any subsequent half-cycle unless the capacitor is discharged, e.g. by a discharge resistor manually connected into circuit (57 and 57a). The pulses may be selectively generated, by operation of switches 64 or 64a to provide selective signalling. The receiver, Fig. 12, may comprise a filter circuit 177 which discriminates against mains supply frequency and passes the higher frequency pulses to an integrator 179. When the integrator voltage exceeds the threshold of Zener diode 184, S.C.R. 187 fires to operate a relay 188 which opens a contactor coil circuit at 189 and lights a neon indicator 197. When the alarm signal has ceased the S.C.R. can be extinguished by operation of push-button 193. A "press to test" circuit is included comprising an elementary form of transmitter including the neon 202 connectable across the power line by switch 201. Modifications of the control switching are described with respect to Figs. 13 and 14 (not shown), the Fig. 14 embodiment employing an indicator plunger type fuse connected across the line terminals by the operation of the control relay.

Abstract: 1,149,088. Strip line couplers. SIEMENS A.G. 29 Sept., 1966 [30 Sept., 1965], No. 43482/66. Heading H1W. A microwave line comprises a strip conductor 5 provided (e.g. by printing) on one side of a dielectric plate 1, the second conductor of the system being formed by a conductive housing 3 within which lies the dielectric plate 1. The vertical sides of the housing are sufficiently high to prevent radiation of energy whereby a cover plate is rendered unnecessary. The housing may have two screened chambers which intercommunicate over a distance sufficient to provide direction coupling between the lines in each chamber. In order to compensate excess inductive coupling, each strip conductor is provided at either end of the coupling interval with portions which project towards the other strip conductor. Input couplings are provided by coaxial sockets on the housing. A dissipative termination may be formed by arranging wedgeshaped resistive members on either side of a terminal portion of the strip conductor. The terminal portion is tapered to a point. Two microwave lines according to the invention may be joined by abutting the respective housings 31, 32 and inserting a metallic clip 34 between the opposed ends of the lines 35. The clip is roughly in the form of a T with resilient horizontal arms 38 which engage and connect together the strip conductors 35. The vertical limb of the T ends in a pair of spring fingers 37 which enter a recess cut in the housings 31, 32 and engage projecting end portions of the dielectric plates 36.
