IPC: H01J9/227
Filed: 1971-12-02
Abstract: 1379047 Luminescent screens HITACHI Ltd 2 Dec 1971 [4 Dec 1970] 56104/71 Heading H1D In the manufacture of a colour television screen by exposing a photo-resist through a shadow mask 1, the apertures lc in the mask are effectively reduced in size by covering the mask with a light attenuating layer 2b and a photosensitive layer 2a which is exposed through the mask to leave light permeable dots 4 smaller than the apertures 1c. The layer 2a may be of material such as polyvinyl chloride which is sticky before exposure but loses its stickiness after exposure; light absorbent material 5 such as carbon is applied to the surface either before or after exposure so that it adheres only to the unexposed areas. Alternatively the layer 2a may be of photoconductive material such as polyvinyl carbazole. The layer 3 is a transparent binding layer which may be omitted. The screen may be of the type including opaque material in the interstices of the phosphor dots.

Abstract: 1,150,479. Semi-permanent store. NIPPON ELECTRIC CO. Ltd. 14 Dec., 1967 [14 Dec., 1966], No. 56879/67. Heading G4A. A semi-permanent store comprises, a plurality of wires arranged in parallel with each other and consisting of non-magnetic electrically conductive wires covered with thin films of a soft magnetic material and a hard magnetic material having uniaxial magnetic anisotropy, a plurality of elongated non-magnetic electric conductors intersecting at substantially right angles with the wires, and magnetized small magnets disposed adjacent predetermined intersections of the wires and conductors. The soft and hard magnetic material can be an alloy of Fe and Ni and a metal Co or an alloy thereof respectively with the easy axis of magnetization of both being aligned in the same circumferential direction or same axial direction of the wire. Drive currents applied to the wires or conductor in the case of axial or circumferential alignment of the easy axis of magnetization respectively, cause read-out currents to occur from the intersections that do not have magnets disposed in their vicinities, on the conductor or wires respectively. The drive current rotates the axis of magnetization which reverts to the easy axis on cessation of the drive current. The current, however, is not sufficient to reverse the direction of magnetization of the hard film. The use of the soft film serves to give a high constant output.

Title: Automatic number transmitting device
IPC: H04M1/276
Filed: 1966-12-22
Abstract: 1,129,170. Automatic exchange systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 Dec., 1966 [22 Dec., 1965], No. 57447/66. Heading H4K. In a number transmitting device, each digit is represented by the distance between two set states in an associated shift register of a group of shift registers connected in series and the set states are shifted through the group and used to generate dialling pulses. In the operator's keyset shown three magnetic core shift registers SR 1 , SR 2 , SR 3  each having eleven stages are connected cyclically to form a closed loop so that stored data can be circulated through the registers in 33 steps. When the operator lifts a receiver a hook switch K 21  is closed and a pulse is passed through a capacitor C 2  and sets a first core TL 1  of a shift register SR 4 . A digit key K 1  to K 0  is closed applying a potential to a corresponding column wire Cd 1  to Cd 0  linking corresponding cores of each shift register. The column wires are connected to a common return conductor Cd m  which links the output cores TA 1 , TA 2  and TA 3  of the shift registers and is connected to a capacitor C 3  which flips a bi-stable circuit MVB 2  to its other state. This causes the set state in the shift register SR 4  to shift to core TL 2 . A wire Ca 1  linking the core TL 1  is pulsed as the core resets and co-operates with the potential on the key column wire and on the common return conductor thus setting the marking core TA 1  and that core of the shift register SR 1  associated with that digit key. When a second digit key is depressed shift register SR 4  transfers the set state to core TL 3  and the marking core TA 2  and a digit core of the shift register SR 2  are set. When a third digit key is operated marking core TA 3  and a digit core of the shift register SK 3  are set and a pulse passes through a capacitor C 4  and triggers a monostable multivibrator MVM. This releases an astable multivibrator MVA for a period of 33 cycles during which it supplies pulses through amplifiers A 6 , A 7  to recirculate the set states through the shift registers SR 1 , SR 2  and SR 3 . As the set states are recirculated they are also applied as a toggle input to a flip-flop MVB 1 . The flip-flop is set and enables an AND gate P in response to set state from the marking core of each shift register and is reset to block the gate in response to the detection of set states from the cores associated with the digit keys. Thus the AND gate is enabled for periods proportional to the selected digits and corresponding numbers of pulses from the multivibrator MVA are passed by the AND gate and operate a relay having a dialling contact CL. A key K 4  may be closed to trigger the monostable multivibrator MVM if a number of less than three digits is to be transmitted or if a three digit number already set up and transmitted is required to be retransmitted. The registers may be cleared by depression of keys K 31  and K 32 .

Abstract: 1376159 Proximity sensors SIEMAG SIEGENER MASCHINENBAU GmbH 20 Dec 1971 [23 Dec 1970] 59060/71 Heading G1N In order to place the end of a metal strip coil 1 in the required position for further processing the end is sensed by an inductive sensor 8 bearing via rollers 10 on the surface of the coil and the sensor output used to control a motor driving the coil 1. Two inductive sensing elements 12, 13 are mounted between the rollers 10 set back from the surface thereof and vertically offset relative to each other so that when the rollers bear against the coil 1 the coil moves past the sensing elements successively as it rotates. The sensing elements 12, 13 are connected to respective coupling elements each supplied by an oscillator. In the retracted position of the sensing head 8 the oscillator outputs are coupled through the coupling elements to respective inputs of a comparator so that no output signal is produced. When the sensing head 8 is moved against the coil the latter damps the oscillator output at the coupling elements and there is again no output from the comparator. However as the head 8 runs over the end of the coil as the latter rotates there is a reduction in the damping of one of the oscillators and an unbalance signal is produced by the comparator. Alternatively the sensing elements may each include primary and secondary windings so that the strip varies the coupling between the coils when the primary is energized. In another arrangement the two sensing arms are connected in respective arms of an A.C. bridge, Fig.4 (not shown) the output of which is fed to an adjustable threshold amplifier. Control circuit, Fig.3 (not shown). This circuit permits the coil to be rotated slowly until an unbalance signal is produced by the comparator. This signal causes an inductively acting pulse generator coupled to the motor driving the coil to operate so that when a predetermined number of pulses have been produced the motor is switched off and a stripper lowered into engagement with the coil. The motor then reverses in direction to allow the coil to be unwound and runs for a predetermined time set by a timer.
