IPC: G11C5/12
Filed: 1964-11-12
Abstract: 1,031,410. Magnetic storage apparatus. STANDARD TELEPHONES & CABLES Ltd. Nov. 12, 1964, No. 46120/64. Heading H3B. Wires are inserted into parallel slots 28 of a ferrite plate 27 of a waffle-iron memory by winding a continuous piece of wire around two spaced parallel rods 10, 11 so that successive upper 25 and lower 26 lengths of the wire between the rods are spaced from one another along the lengths of the rods by the distance between the slots 28, and inserting the successive lengths of wire into the slots. The rods 10 and 11 are provided with a helical thread having twice the pitch of the slots, and after winding the wire on the jig the latter is lowered so that the lower half 26 of the wire is lowered into alternate slots 28 and followed by the upper half 26. Alternatively, the two halves may be clamped coplanar before insertion. After anchoring the wires they are severed along rod 10 and rod 11 withdrawn. A polished substrate coated with an isotropic magnetic film is placed over the wired ferrite plate; 30 is an access matrix.

Title: Improvements in or relating to Colour Television Systems and Apparatus
IPC: H04N11/16
Filed: 1966-10-17
Abstract: 1,157,980. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 17 Oct., 1966 [20 Oct., 1965], No. 46271/66. Heading H4F. In the PAL system of colour television the use of a delay line demodulator at the receiver causes the chrominance signal to be averaged over two successive lines. Where averaging over two lines is also used at the transmitter for the purpose of transcoding or during transmission one or more times for the purpose of phase correcting the subcarrier, the finally produced chrominance signal at the receiver may be the average of three or more lines. This incurs a disadvantage in that amplitude changes in the luminance signal are not in step with the corresponding changes in the final chrominance signal. A visible deterioration is produced in the reproduced image in the form of a blurring of horizontal colour edges. In accordance with the invention the disadvantage is removed by subjecting the luminance signal to a delay of one or two lines. The delay may be effected at the transmitter or receiver, or during transmission. The delay may be introduced directly at video frequency or by first modulating the luminance signal on a carrier frequency which is chosen to be a multiple of colour subcarrier frequency which is chosen to be a multiple of colour subcarrier frequency. Where the delay is effected at the receiver the delay line in the chrominance demodulator may be used by translating the luminance signal through the line on a carrier signal. The delay time may be adjusted slightly from the nominal value: (1) to allow for the inherent differences in luminance and chrominance transmission time due to the differing signal band widths; and (2) to introduce aperture correction in the vertical direction.

Title: Improvements relating to control devices for inductive loads
IPC: H02P7/29
Filed: 1967-10-18
Abstract: 1,201,368. Automatic current control. ROBERT BOSCH G.m.b.H. Oct.18, 1967 [Oct.20, 1966], No.47351/67. Heading G3R. [Also in Division H2] A series motor 10 is supplied from battery 12 through parallel-connected transistors 13, 14, 15, associated with equalizing resistors 16, 17, 18, and free-wheeling diodes 21, 22, 23. The voltagedrops across the equalizing resistors are added by means of resistors 37, 38, 39, and the resultant voltage is fed to comparator 27 connected to pulse amplifier 24 which responds to the difference between a reference voltage derived from potentiometer 28 and the voltage representing the mean current of the motor to control the duty ratio of the transistors 13, 14, 15. The tapping 29 of the potentiometer 28 is connected to the comparator 27 through a delay network 33, 34, 35, and an integrating network 42, 43, 45, is connected between the junction of the resistors 37-39 and earth. The pulse amplifier has a feedback circuit comprising capacitor 25 and resistor 26. If the transistor 13, for example, is short-circuited, the associated resistor 37 is connected directly to the negative pole of the battery so that a high potential is developed at summing-point 36 for blocking the pulse amplifier and protecting the other transistors. When the reference potentiometer 28 is set to zero, the motor 10 is stationary, transistor 60 being conductive and transistor 64 being blocked. Feedback capacitor 25 is charged, and transistor 65 is conductive to block the transistors 66, 67, and 13, 14, 15. If the reference voltage is increased, the motor receives current and starts to rotate until the feedback derived from resistors 16, 17, 18, reduces the potential at junction 27 sufficiently to block the transistor 64. The transistors 66, 67, are reliably blocked by the charge on capacitor 99 so that the transistors 13, 14, 15, change abruptly from the conductive to the non-conductive state. Current flowing through the motor and the diodes 21, 22, 23, decreases exponentially until the transistor 60 is blocked again and the cycle is repeated. When the motor voltage across capacitor 84 exceeds the Zener voltage of diode 78, the pulse amplifier is blocked. A current-limiting arrangement comprises rectifier 105 and resistor 106 which restrict the gain of the pulse amplifier.

Abstract: 1326799 Line transmission systems WESTERN ELECTRIC CO Inc 6 Oct 1970 [8 Oct 1969] 47393/70 Heading H4R Adjustment of an equalizer including a plurality of adjustable transmission networks having different passbands is controlled by a set of signals produced by passing a sweep frequency test signal through the equalizer, comparing the output with a reference signal and modifying different parts of the output in the different passbands in accordance with the result of the comparison. As described an equalizer 13 including a number n of transmission networks having different passbands and different "bump" type transmission characteristics is monitored by applying a sweep frequency test signal to the transmission path at 11. The resultant output is received at a detector 14 and compared at 16 with an ideal response p oduced by a reference source 15, the difference or error signal 25 being applied to n multipliers 19-1 to 19-n. The output signal of the equalizer is also applied at 22 to n bandpass filters 17-1 to 17-n each passing a transmission band corresponding to a corresponding transmission network to a detector 18-1 to 18-n. The outputs of the detectors are each multiplied by the error signal 25 and after integration at 21-1 to 21-n applied to a corresponding control input X1 to Xn of the equalizer. The control signals may be in the form of heating currents through heating elements which influence thermistors in the transmission networks. The error or difference signal 25 can be differentiated and the control signals fed to "Q" factor control terminals of the equalizer to vary the "stiffness" of each transmission network. The circuitry may be duplicated to effect both types of correction. Alternatively the error signal may be squared and used in conjunct on with a polarity detector to effect squared error adjustment.

Abstract: 1369065 Sonar systems THOMSON-CSF 15 Oct 1971 [16 Oct 1970] 48171/71 Addition to 1225747 Heading H4D  The pulse - duration - modifying system of the parent Specification 1,225,747 (Division H4) is adapted by provision of a time-division multiplex arrangement to enable simultaneous processing of several input signals. In the embodiment shown N input signals S 1  ... S n  (e.g. occurring in N reception channels of a panoramic sonar device in response to a transmitted F.M. pulse) are frequency shifted by N pairs of modulators 101, 102 so that the centre frequency in each case is down-converted to zero frequency, giving "real" output components X 1  ... X n  and "imaginary" output components Y 1  ... Y n . The local oscillator frequency fed to each modulator may be adjusted to compensate for Doppler shifts of the S 1  ... S n  signals. The components are multiplexed at 4, and converted to digital form at 5. The digitized X components are stored in N memories of a store 7, and the digitized Y components are stored in a further N memories of store 7. The store memories are circulatory and provide time-compression of the components. The time-compressed components are multiplexed by store read-out and selector circuits 8, then converted to analogue form at 10 and translated in modulators 12 to a frequency suited to a dispersive delay line 14 which provides further time-compression of the combined X and Y components and effectively correlates them with a replica of the transmitted sonar signal.
