Title: A method of producting a pattern on a surface
IPC: G03G19/00
Filed: 1965-11-03
Abstract: 1,080,107. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 3, 1965 [Dec. 30, 1964], No. 46487/65. Heading H3B. [Also in Divisions B6, G5 and H1] A method of producing a printed circuit on a surface comprises the steps of generating a magnetic line replica of the pattern on a magnetizable support, covering the support with an electrically insulating layer and developing the replica through contact with fine magnetic particles. As shown, Fig. 1, a probe 14 is used to draw a pattern of very fine magnetized lines 30 on a coating 12 of magnetic oxide on a plastic base 10. The coating 12 is covered with an electrically insulating layer 32, Fig. 2 (not shown), prior to development by immersion in a magnetic colloid bath. After development the circuit pattern is plated by either an electroless or electroplating operation the plating metals being copper, gold or silver. The insulating layer bearing the plated pattern may then be stripped from the oxide-coated plastic base. Further copies of the printed circuit may subsequently be obtained from the patterned base through the application of the above method. In a further example of the method a memory plane of the type used in magnetic storage memories for data processing machines is produced. A magnetic oxide coated plastic tape has placed upon the oxide layer an array of thin film magnetic dots in horizontal rows and vertical columns. Next, parallel lines are " written " in the magnetic oxide coating by passing a probe 14 along the tape to cross diametrically over the spots constituting the different horizontal rows. An insulating layer of evaporated silicon monoxide is then placed over the imaged dots and development is effected in a magnetic colloid. The lines are then plated prior to complete demagnetization in an A.C. field. The probe 14 is then used to " write " continuous parallel lines over the dots in the vertical columns before coating the dotted surface, by evaporating on to it silicon monoxide. The vertical lines are then developed in a magnetic colloid and finally plated prior to demagnetization.

Abstract: 1,022,965. Signal generators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 27, 1963 [Nov. 30, 1962], No. 46894/63. Heading H3A. A decade signal generator which can be set to any one of a plurality of discrete output frequencies within a predetermined range, e.g. in steps of 100 kc/s. in the range 70- 100 Mc/s. comprises an output oscillator 2 coupled in a first AFC loop 1 in which its frequency is compared with that of a course step oscillator 3 and a fine step oscillator 4 and auxiliary AFC loops 5 and 6 in which the oscillators 3 and 4 are stabilized with reference to a crystal oscillator 8. Rough step oscillator 3 is approximately set by the 10 Mc/s. decade control switch 30 and its output is compared in unit 9 with harmonics of the 10 Mc/s. crystal reference 8 produced in harmonic generator 7. Oscillator 3 operates at either 60, 70 or 80 Mc/s. and its approximately set output signal when mixed with the relevant harmonic provides a signal which can be selected by low pass filter 10 and applied to frequency control device 11 to lock the frequency of oscillator 3 to that of relevant harmonic. The output of oscillator 4 which operates in the range 10-20 Mc/s. is applied to a divider unit 13 which divides by a number between 1000 and 2000 selected by the 1 Mc/s., 100 kc/s. and 10 kc/s. decade switches 31-33 and the divider output is compared in unit 14 with a 10 kc/s. signal derived from the crystal source via unit 12 which divides the source signal by 1000. The output from mixer 14 is selected by low-pass filter 15 and controls oscillator 4 whereby the output from divider 13 is 10 kc/s. The output oscillator 2 is roughly set by the 10 Mc/s. switch 30 and its output is mixed in unit 17 with the output of the rough step oscillator 3. The difference frequency is selected by filter 19 and compared in mixer 20 with the output of fine step oscillator 4. The difference frequency selected by filter 22 controls the frequency of oscillator 2 to a value equal to the sum of the frequencies of the signals supplied by oscillators 3 and 4. In the absence of a control signal in AFC loops 1 and 5 amplifiers 25 and 26, with positive feedback paths 24 and 27 respectively, oscillate at approximately 50 c/s. and sweep their respective oscillators 2 and 3 to a frequency at which lock-in occurs. In a second arrangement, Fig. 2 (not shown), the discrete steps are reduced to 100 c/s. and a third auxiliary AFC loop is provided.

Abstract: 1370177 Crash restraint bags GENERAL MOTORS CORP 12 Oct 1972 [20 Oct 1971] 47094/72 Heading B7B  An inflatable cushion actuation and monitoring circuit for a vehicle includes an electrically operated device, such as a squib, normally actuable in the event of a collision from a primary source, such as a storage battery, but actuable from a capacitor in the event of failure of the primary source during a collision. Monitoring circuitry including an indicator lamp is provided to indicate when a monitored voltage either exceeds a first reference voltage or drops below a second reference voltage to indicate malfunctioning in the actuation circuit. An indication is also provided of whether the capacitor is charging or open circuited. A fuse indicates, by its condition after a collision, if the collision exceeded a certain g level. If the collision exceeded, say 15 g, and the cushion is not inflated, the fuse will be open circuited; on the other hand, if the fuse is not open circuited the g level must have been below the level required to cause inflation. A further fuse indicates, by its condition after a collision, if the g level was above the capabilities of the actuation circuit. An indicator lamp indicates loss of pressure in the pressure vessel used for inflation. A reversible electrolysis cell, e.g. a silver microcoulometer becomes plated on one of its electrodes with metal; the amount of plating being indicative of the time a transistor included in the actuation circuit is non-conductive due to malfunction in the actuator circuit.

As described, an operator inserts one or more coins into the coin slot 42. The coin or coins may be returned through a shoot (66), (Fig. 8, not reproduced), to the ticket-dispensing aperture 28 (Fig. 1) (a) by a rejector relay (see Fig. 4) when the computer is not ready for computation as indicated by a "ready" lamp 38, (b) by a coin discriminator separating out invalid coins, or (c) by a coin return button 40 (Fig. 1). Valid coins are counted, stored in a reservoir (64), (Fig. 8), and then a signal produced on a signal line A (Fig. 4). The number of coins inserted determines the illumination of either a "single" 32 (Fig. 1) or "combination" 34 lamp to indicate whether one, or several handicapping systems in combination, are to be selected. The operator selects these by depressing one or more illuminated buttons 30. Provided the appropriate handicapping systems are available for use as indicated on a signal line B (Fig. 4), then the number of buttons 30 depressed is summed by a valid request counter, and compared with the quantity of money inserted. On correspondence, a computing latch relay is activated and a computing lamp 36 (Fig. 1) illuminated. The data then calculated by the computer using the selected handicapping system(s) is fed to a printer (52), (Figs. 6, 7, not reproduced), and a ticket printed, cut from the stock by a cutter (70) (Figs. 9, 10, not reproduced), and delivered. Finally, the money and valid request counters are reset by the computer. Any malfunction results in the computer extinguishing the "ready" lamp 38 (Fig. 1), and causing issuance of an appropriately printed ticket. Ticket.-The ticket is printed with an indication of the race number and the handicapping system(s) employed, and the best three horses together with their ratings.

Abstract: 1,118,270. Multiplex pulse code signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 4 Nov., 1966 [10 Nov., 1965], No. 49552/66. Heading H4L. In a circuit for recognizing a particular sequence of pulses in a pulse transmission system such as the synchronizing combination in a PCM signal, the pulse train is applied to a shift register, the contents of which control a backward-forward counter from which an output is obtained when the particular sequence has been either received in full or, if required, in part. As described, with special reference to the recognition of the combination 1111, the incoming pulses at E are applied to a shift register SR, through which they are shifted by a clock pulse T (Fig. 4c) at regular intervals. The output signal of the first stage of the shift register (Fig. 4a) is applied to an AND gate U1, which also has an input from the clock pulse T. The output pulse train from the AND gate U1 (Fig. 4e) controls a counter Z to count forwards. The output signal of the last (fourth) stage of the shift register (Fig. 4b) is applied to an AND gate U2, which also has an input from an inverse clock pulse T INV  (Fig. 4d). The output pulse train from the AND gate U2 (Fig. 4f) controls the counter Z to count backwards. The stage 4 of the counter Z renders an output signal to the output A via an OR gate 0. An output signal from the stage 3 of the counter Z may also be made available via the OR gate 0 to the output A or, by applying a control signal Sp to an INHIBIT gate U7, be blocked off. In a second embodiment, Figs. 5, 6 (not shown) the shift register (SR) has five stages. The output of the first stage (Fig. 6a) is applied to a gate (U6) and to an INHIBIT input of the gate (U4). The output of the last stage (Fig. 6b) is applied to the gate (U4) and to an INHIBIT input of the gate (U6). The output from the gate (U6) (Fig. 6h) is applied to a gate (U1), which also has an input from the clock pulse (T). The output from the gate (U4) (Fig. 6 i ) is applied to a gate (U2) which also has an input from the clock pulse (T). As in the first embodiment, the output from the gate (U1) (Fig. 6e) controls a counter (Z) to count forwards, and the output from the gate (U2) (Fig. 6f) controls it to count backwards, output being obtained from stages 3 or 4 thereof. In a third embodiment, Figs. 7, 8 (not shown) the outputs from the first and last stages of a five-stage shift register (Figs. 8a, 8b) are applied respectively to gates (U1), (U2) and to the two inputs of a gate (U3). The output of the gate (U3) (Fig. 8k) is applied to an INHIBIT input of gate (U5) which also has an input from a clock pulse (T). The output from the gate (U5) (Fig. 8l) is applied to the gates (U1), (U2). As in the other embodiments the outputs of the gates (U1), (U2) (Figs. 8e, 8f) control a counter (Z) to count forwards and backwards, and output is obtained from stages 3 or 4 thereof.
