IPC: H04N3/15
Filed: 1968-02-23
Abstract: 1,253,035. Television. PLESSEY CO. Ltd. 14 Feb., 1969 [23 Feb., 1968], No. 8993/68. Heading H4F. [Also in Division G1] A light detector arrangement having a plurality of light detectors, e.g. photo-diodes arranged in a matrix, each of which is arranged to be initially charged, and in which the amount of light falling on a selected detector is determined by the charge remaining on the detector after exposure, comprises means, effective during the time a particular light detector is selected, to re-charge the selected detector and to determine the state of charge thereof before and after it is re-charged, and means to derive an output signal corresponding to the difference between these two states, which output signal is proportional to the amount of light falling on the selected detector. As shown, the state of charge of a photo-diode D is sampled by means of a transistor Q1 the current I flowing through it being proportional to the voltage V on its gate. This current I is fed to an output resistance R 1 , which is common to all the diodes of the array, via two series connected transistors Q 2  and Q 3  when potentials are applied to the row and column conductors x and y of the selected diode. A comparison of the state of charge of the diode D before and after it is recharged from the negative-Vbb supply line during the period of pulse C, is obtained by comparing the voltages across resistance R 1  immediately before and after re-charging, i.e. during the time a potential is applied to the y conductor. This is effected by applying pulses B and D to transistors Q 5  and Q 4  causing them to pass the voltages to differential amplifier Q 6 , Q 7 . An output is taken from transistor Q 6  and fed via transistor Q 11  to the gate of transistor Q 12  which acts as a store, and the required output voltage Vo which is proportional to the output of the differential amplifier is taken across a load resistor R 2 . This output signal remains until the next succeeding light detector is assessed. All the transistors shown comprise metal-oxide-silicon-field-effect-transistors.

Abstract: 1,266,029. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 20 May, 1969 [3 Sept., 1968], No. 25658/69. Heading G4C. In data processing apparatus comprising a store, a switching network connecting an address register to an effective address register for the store is controlled by a blocking register and at least one status register, the number of status registers corresponding to the number of entries in the blocking register, an address blocking register and a mask register being provided for processing a sequence of failed addresses and for inserting control data in the blocking and status registers whereby access to a portion of the store affected by faults in the addressing circuitry is prevented. When a first failed address is detected it is inserted into the address blocking register and the mask register is set to all ones. When any further failed address is detected, the current contents of the address blocking register are replaced by the corresponding-bits AND of the further failed address and the current contents, and the current contents of the mask register are replaced by the corresponding-bits AND of the current contents with the result of the corresponding-bits NOT-EXCL-OR of the old contents of the address blocking register and the further failed address. For all i, the ith status register is set to one in each position (from the left) up to and including that corresponding to the ith one (if present) in the mask register, and the ith position of the blocking register is set to the bit value in the position of the address blocking register corresponding to the ith one in the mask register. The switching network performs an address mapping such that if one of the faulty addresses appears in the address register it is converted on transfer through the switching network into the effective address register, into an address not detected to be faulty, as follows. Depending on the leftmost bits in the address register, the contents of the first so many of the status registers are used, and a one bit gap is created in the address at the bit positions corresponding to the rightmost one in each status register so used, by displacing bits of the address to the left as necessary, the first, second ... gaps being filled with the first, second ... bits from the blocking register respectively, the last of the bits so used being inverted. The effect is to exclude those addresses agreeing with the contents of the address blocking register in the bit positions corresponding to ones in the mask register. If the address in the address register would map into an address too large for the store, overcapacity is signalled.

Abstract: 1,266,085. Lasers. WESTERN ELECTRIC CO. Inc. 10 June, 1970 [16 June, 1969], No. 28086/70. Heading H1C. In a laser communications system, a semiconductor laser is continuously pumped at a temperature chosen such that self-induced pulses occur in its output, the pulse repetition frequency (PRF) and the pulse width being controlled by an amplitude modulated signal whose frequency is the same as, or a harmonic of, the PRF. Fig. 2 shows a P-N junction laser 20 biased by a source 11 which supplies a continuous current of 1À1-3 times the lasing threshold current. At temperatures of 77-110‹ K. for a GaAs diode, selfinduced pulses occur in the output, with a microwave PRF. The output pulses are detected by photodiode 24, and the resulting microwave signal is amplified at 25 and added to the pumping current to stabilize the PRF. By modulating the gain of amplifier 25, pulse width modulation (PWM) of the stabilized output is achieved. The signal added to the pumping current need not be derived from the output, since the PRF will lock on to any applied microwave signal; thus, Fig. 1 (not shown), the output pulses may be modulated simply by coupling an amplitude modulated microwave oscillator (12) to the pumping circuit. In another embodiment, Fig. 3, a feedback signal is derived from the small variations of pumping current produced by the selfinduced pulses, the variations being built up by a microwave resonator 31. The losses of the resonator are modulated by a variable ferrite window 33, and hence the feedback signal is amplitude modulated and a PWM output is obtained. Optical feedback may be used, Fig. 4 (not shown), using a mirror (43) and lens (41) as a second resonator within which there is a modulator such as a Kerr cell to amplitude modulate the feedback and give a PWM output. Control of the pulse width by amplitude modulated signals is stated also to be applicable to semiconductor lasers pumped optically or by an electron beam. The construction of a suitable GaAs diode is described.

Abstract: 1296683 Laminates KIMBERLY-CLARK CORP 17 Oct 1969 [23 Oct 1968 29 April 1969 10 Sept 1969] 51144/69 Heading B5N [Also in Division D1] A high loft, non-woven fabric is made by feeding a web of highly drafted fibres or longitudinally extending monofilaments embedded at spaced points in an open pattern adhesive layer on to a surface 37 which is heated to cause the layer to become tacky. The web is then impinged against a blade 38 which gathers the softened adhesive layer to form a consolidated backing and loops the fibres. As shown, a continuously moving transfer belt 15 is coated with a pattern of adhesive 16 applied by a patterned roller 20 from an adhesive bath 23. A web of fibres 14a and another web of fibres 14b of different type or colour is applied to the adhesive pattern. The coated web passes over a heated drum 29 which causes the adhesive to become tacky and adhere to the web which is then separated from the belt 15 after passage over roller 19. The web is conveyed to heated forming drum 37 where the adhesive again becomes tacky and is consolidated into a continuous backing by the edge 39 of the gathering blade 38. The fibres are thus formed into loops 40 which may twist to be in planes transverse to the original direction of the fibres in the web. The fabric collects on the take-away surface 41 which may be cooled by air-blowing device 43 and carried away by the conveyer 42. The adhesive backing may be only partially consolidated and stretched to separate part of the backing to produce a stretchable fabric. The open pattern of the adhesion layer is preferably of diamond form but may be lines transverse to the longitudinal direction of the web. The elements of the web are flexible fibres of e.g. nylon, rayon or the heat-settable polyolefins, polyesters and polyacrylics. Pleats may be formed in the fabric by adjusting the relative speeds of drum 37 and conveyer 42. The angle of the blade edge makes with the tangent to the drum at the point of contact may be varied preferably between 17 and 74 degrees. Also the surface 41 may be lowered which affects the end product. If the distance between the portions of adhesive in the machine direction are constant the loops are of uniform height; however, with a diamond pattern of adhesive they vary regularly throughout the fabric. The loops may be sheared to give a cut-pile surface. The open pattern of adhesive applied to transfer belt 15 may be interconnected by relatively thin webs of the adhesive by rotating the roller at a speed different from that of the belt 15. Examples of adhesives used are plasticized polyvinyl chloride and the acrylates. Scrim may be attached to the backing layer.

Abstract: 1305729 Counter-pressure filling device; dispensing measured quantities of liquid GIMSON & CO (LEICESTER) Ltd 21 Sept 1971 [2 July 1970] 32198/70 Headings B8N and B8T A device for filling kegs with liquid under pressure consists of two cylinders 10, 11 one of which is filled from a liquid supply whilst the other is emptied into the keg, the filling and emptying being controlled by trips 31, 32, 33, 34 which operate on a relay 52 and three-way valves 16, 17, each valve being connected to one cylinder and the liquid inlet 18 and outlet 20. When both cylinders are empty, gas is introduced into both cylinders through inlet 28 until a required pressure is recorded on the meter 30, whereupon the three-way valve 16 is set manually to introduce beer into the cylinder 10. When the cylinder is filled, the piston 12 is urged against the plunger (35), Fig. 2 (not shown), of trip 31 and a switch (40) is actuated, thereby opening an air passage from the pressure source 48 through line 53 to the relay 52, the trip 33 still being open since the piston 13 rests against the plunger of trip 33. The air pressure moves relay 52 so that air pressure from the source 46 acts, through line 23 on valve 16 to connect the cylinder 10 with the outlet 20, and through line 24 on valve 17 to connect the cylinder 11 with the beer supply. The piston 13 then moves upwards and piston 12 downwards until the trips 32, 34 and relay 52 reverse the valves 16, 17. The two three-way valves 16, 17 may be replaced by a valve unit (57), Fig. 3 (not shown), having two gear operated valve members (59), (60), the members being reciprocably and alternately connected to the beer inlet and outlet and operated in synchronism by a pneumatic cylinder (65). The volume capacity of the cylinders 10, 11 may be altered by means of a screw collar where pneumatic trips are provided. The cylinder (65) may be controlled by an electric-circuit having ferro-activated proximity switches TPS1, TPS2, BPS1, BPS2, Fig. 4, connected to a double solenoid pneumatic valve 74. The circuit, Fig. 5 (not shown), incorporates a counting device (80) to stop the operation of the device after a predetermined number of cycles, and a mechanism (82) which allows CO 2  to be blown through the valve 79 and the outlet pipes for a predetermined time.

Abstract: 1326701 Pattern breaker for knitting- machines STIBBE-MONK DEVELOPMENT Ltd 23 Feb 1972 [29 April 1971] 12267/71 Heading D1C [Also in Division G3] A pattern disc breaker for use with circular machines comprises a mandrel for holding several discs, the mandrel being movable relative to teeth breakers, means for controlling selection of the breakers and controllable means for rotating the mandrel from one tooth position to another, whatever the tooth spacing. The discs 1 are assembled on a mandrel 2 and broken by breakers 39 selected by solenoids 77 at the dictates of a pattern tape. The Mandrel. The mandrel 2 may be spaced at different distances from the breakers, to accommodate discs of different diameter. One end of the mandrel is supported by a notched disc 12, located by a pin 14 engaging holes 12b so that the notches 12a at different spacings from the holes can support the stem 9 of the mandrel. The location of the mandrel is monitored by reed switches 16 and magnets 18. The other driven end of the mandrel is suported in a movable carriage, which maintains the drive connection. In an alternative embodiment, the breakers are movable towards the discs by different distances as selected by one of a bank of cams (220, Figs. 7, 8 not shown). The Breaker Unit. The breakers 39 are movable towards the discs by interruptors 55 selectively lowered behind them, and supported in a movable block 43, 45. The interruptors are lowered by pivoted levers 58, actuated by vertically movable selectors 72. The selectors are raised by springs 74 when the armatures 76 of solenoids 77 are withdrawn from cut-outs 72c. Solenoid Selection. The solenoids are controlled by a multi-track tape, each track having information relating to several solenoids. Each track has a reader feeding information stores. Selected selectors operate microswitches 235, so that faulty selection can be detected and operation of the unit stopped. Drive and Control.
