Title: Phase modulated magnetic recording and reproducing system
IPC: G11B20/14
Filed: 1964-10-26
Abstract: 1,036,188. Coding and decoding binary signals for recording and playback; electric digital data storage. ANELEX CORPORATION. Oct. 26, 1964 [Feb. 3, 1964], No. 43487/64. Headings G4C and G5R. In a magnetic recording and playback system a sequence of binary digital signals modulates an alternating voltage of predetermined frequency by phase inversion once for each occurrence of one value (e.g. the value 1) in the sequence. In effect this means that a zero is recorded as one cycle of the predetermined frequency and a one is recorded as a half cycle of half the predetermined frequency. In Fig. 1 anti-phase square waves A and B are supplied to gates A1 and A2 respectively which are in opposite states. The input data is synchronized with the clock pulses and supplied to gate A3 which is opened by positive pulses of wave A, so there is an output from gate A3 whenever a " one " occurs in the input data; this output changes the state of flip-flop FF which in turn reverses the states of gates A1 and A2. The output from A1 or A2 passes through OR1 and switches S4 and S1 to a write amplifier 7 and a record head 6. The switches S4 and S3 may be manually or electronically operated to establish write and read periods respectively, and switches S1 and S2 may be manually controlled or may be closed electronically when a pattern of apertures on the record disc 1 read by photo-cells 5 matches a desired address code supplied to comparator 11. Decoding.-The waveform D detected by the playback head 8 is amplified and converted to a pattern of square waves E1 by amplifier 9. An inverter I2 produces the complement #E1 of E1 which is delayed in unit D1 by more than half but less than a whole period of the signal voltage A, e.g. by 1À2 Ás. if the frequency of A is 500 kc/s. The output E2 is delayed by a further amount, e.g. 0À6 Ás. such that the total delay is less than one period, to give a signal #E3À Inverters I3 and I4 produce the complements #E2 and E3, of E2 and #E3. The six signals E1-3 and #E1-3 are fed as shown to three AND gates A4-6, and it is shown that there is an output from A4 when the input signal was a zero and an output from either A5 or A6 when the input signal was a one. The two final outputs may be combined in OR3 to give reconstituted clock pulses. When required for gating purposes a zero or a one may be written at the beginning of each sequence of data, and the detection of this bit at 15 may be used to set a flip-flop (not shown) to control the operation of circuitry interpreting the output of the system.

Abstract: 1506529 Lampholder ASTONIA METAL PRESSINGS Ltd 21 Oct 1976 [29 Oct 1975] 44523/75 Heading H2E A locking means prevents disassembly of a switched lampholder when the integral switch is ON. Coupling nut 13, which secures lower part 12 to upper part 11 of the housing, has a plurality of recesses (45, Fig. 2, not shown) on its inner surface into which the outwardly turned end 44 of U-shaped detent spring 40 engages, preventing the unscrewing of 13 for disassembly but enabling rotation the other way for assembly. With switch bar 17 in the OFF position as shown, projection 49 (solid line) is adjacent projection 48 of detent spring 40 and further movement of 49 to the right beyond the normal "OFF" position brings 44 out of engagement with a recess in 13, enabling 13 to be unscrewed. Connection between plungers 16 and fixed flex terminals (33, Fig. 2, not shown) is by contact bar 22 having contacts 24 fixed to an insulating rod (23) urged into detent slots of different depths (29, 30, Fig. 2, not shown) in switch bar 17 contact being made between 24 and the terminal (33) in one position and not in the other.

Filed: 1971-09-24
Abstract: 1359055 Ignition system ROBERT BOSCH GmbH 24 Sept 1971 [28 Sept 1970] 44611/71 Heading F1B In an ignition system for an internal combustion engine comprising an ignition coil 14 with primary 14a and secondary 14b windings, spark plug 16 and a triggering device for supplying signals to a switching device 12 to periodically open and close the primary circuit, a monitoring device 9 also responds to the triggering signals and includes a timing circuit 23 for opening the primary circuit when a signal is not applied to the switching device 12 during period which exceeds the longest period between consecutive triggering signals when the engine is running. The timing circuit comprises a capacitor connected in series with a charging resistor across a D.C. voltage source and the monitoring device includes a discharge device triggered by the triggering signals for discharging the capacitor and means responsive to the charge on the capacitor exceeding a predetermined value for opening the switching device in the primary circuit. Thus currents flowing in the primary circuit during standstill of the engine, while the ignition switch 10 is closed, are prevented. During running of the engine capacitor 17 charges but is periodically discharged through element  19 when the latter is triggered by switching element 12 which also opens and closes the primary circuit. If the engine is stopped, switch 10 remaining closed, the switching device 12 ceases to operate so that capacitor 17 is no longer discharged and after a time, e.g. 1 second, device 23 passes a signal to the switching device 12 to open the ignition circuit. Two transistorized circuits are described one depending upon a cam operated mechanical switch and the other a magnetic pulse generator 70, Fig. 3, for the triggering signals. As shown in Fig. 3, in a monitoring device 113 capacitor 114 charges through resistor 115 but is periodically discharged due to transistor 118 being rendered conductive by a pulse derived from the pulse generator 70. When the engine is stopped the pulse generator no longer triggers and capacitor 114 is no longer discharged and hence after a time reaches the breakdown voltage of Zener 123 to thereby turn on transistor 124 and cut off transistors 91, 101, 103 and power transistor 106 to open the ignition circuit.

A press comprises a plate 46 carrying the upper part 53 of a die and hooks 64 pivoted on the plate for engaging the under side of a lower plate 60, thus locking together the parts 53, 54, 59 of the die while a workpiece is calibrated hydraulically therein. An upper plate 41 mounted on the press-ram 40 has piston-andcylinder units 43 supporting the plate 46, a central unit 51 for operating a plunger 49 and outer units 70 for operating the hooks 64. A retaining ring 56 for holding together the sections of the divided die 54 is carried by a base 58 supported on an air cushion, the base section 59 of the die resting on a seating 61 on the lower plate 60. Operation.-The blank 78, filled with water, is lowered in the die 54 until this is clamped in the ring 56. Further lowering of the ram carries the upper die 53 against the flange of the blank and the base of the blank against the lower die 59. The blank is then deformed to fit the dies, Fig. 2 (not shown). At this stage, plate 46 stops and further downward movement of the ram 40 and plate 41 forces oil out of the cushion cylinders 43 and closes the hooks 64 on to the plate 60. During deformation, water from the blank raises a piston 48 surrounding the plunger 49. The blank is calibrated hydraulically by the plunger 49, the volume being controlled by cams (80), Fig. 3 (not shown). When the ram 40 is raised, the assembly moves upwards until base 58 is stopped by the table 76. Continued movement releases the hooks 64 and withdraws the die 54 from clamp ring 56. A plate 55 carrying the die 54 may be swung clear of the ram by a fluid-pressure control to facilitate loading.
