Title: Improvements in control circuits of cathode ray tubes
IPC: H04N3/20
Filed: 1961-12-01
Abstract: 968,719. Cathode-ray tube protection circuits. COMPAGNIE FRANCAISE THOMSONHOUSTON. Dec. 1, 1961 [Dec. 1, 1960], No. 43061/61. Heading H4T. Damage to the screen of a television picture tube when the receiver is switched off, due to the thermal inertia of the cathode, the charge on the E.H.T. smoothing capacitor and the cessation of scanning, is prevented by means of a threshold device comprising a Zener diode 5, which, in the embodiment of Fig. 1, is connected between the final video amplifier and the cathode 6 of the picture tube 8 such that the cathode current of the latter flows through diode 5 in the reverse direction or, in the embodiment of Fig. 2, is connected in opposition with a conventional diode 12 such that the negative bias (charge on capacitor 4) on the control grid 7, on switching off, can only discharge through the Zener diode 5 in the reverse direction. An advantage of the latter embodiment over known arrangements in which a protective bias is maintained on the control electrode of the tube. is that the resistor 14 and potentiometer 15 may have low values so that the circuit has a small time constant and brightness adjustment is therefore not affected by the delay inherent in the known arrangements which have large time constants. In the embodiment of Fig. 1, the diode is shunted by a capacitor 4 which bypasses it for video signal frequencies.

Title: Improvements in or relating to control systems for data multiplex systems
IPC: G06F13/22
Filed: 1964-10-27
Abstract: 1,017,879. Multiplexing systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 27, 1964 [Nov. 29, 1963], No. 43684/64. Heading G4A. A system for multiplexing data from a plurality of input devices on to a common output channel includes a timing circuit associated with each device to indicate the number of sampling intervals which remain before new data will be supplied from that device, and a selection circuit adapted to output during a sampling interval the data from the device with the (or a) smallest associated said number. Application to supplying data to a computer is mentioned. Input devices 1, 2, 3, 4 (Fig. 1, not shown) supply parallel words to respective one-word buffer stores every 3, 4, 5, 5 Á secs. respectively. Each input device, when it supplies a word, also sends a " ready " signal. Figs. 2a, 2b (not shown) show a control circuit which produces, every Á sec., one or none of four " select " signals to gate the contents of a corresponding one of the buffer stores to a common output cable. The control circuit is controlled by a ring counter which cycles once every Á sec. Each " ready " signal sets a corresponding " ready " flip-flop 61, 62, 63, 64 (Fig. 2a, not shown). In the zeroth of five phases of each cycle of the ring counter, the set state of any " ready " flip-flop results in the setting to 3, 4, 5, 5 respectively of a corresponding binary clock counter and the setting of both a corresponding " available " flip-flop and a corresponding " sample " flip-flop. The " ready " flip-flops are reset during the first phase of the ring counter cycle. During the first, second and third phases those clock counters with ONES in their 4, 2 and 1 stages respectively, reset their corresponding "sample" flip-flops (provided the corresponding " available " flip-flop is still set-see below). As soon as all the " sample " flip-flops have been reset, an inverter 186 (Fig. 2b, not shown, bottom) sets again that or those " sample " flip-flops last reset. During the fourth phase of the ring counter cycle, a " select " signal is produced from the one of four AND gates 211, 212, 213, 214 (Fig. 2b, not shown) corresponding to the lowest numbered " sample " flip-flop still set (if any). This " sample " signal, besides gating the word in the corresponding buffer store to the output cable, also resets the corresponding " available " flip-flop so that the data in the buffer store cannot be gated to the output cable twice. During the zeroth phase of the next ring counter cycle, the clock counters are all decremented by one, and the above procedure repeats, and so on.

Title: Vacuum seal unit
Inventor: SHEPARD STANLEY CARDEN
IPC: F16J15/16
Filed: 1965-10-15
Abstract: <PICT:1055020/C6-C7/1> A continuous linear vacuum deposition system consists of a number of chambers of cylindrical glass tubing joined end-to-end Fig.1 (not shown) by vacuum units (see Division F2), which allow introduction of a substrate 47 into the system and its subsequent transfer between the chambers. Each chamber is traversed vertically by a length of similar tube housing a heater 15 in its upper end and connected at its lower end by way of high vacuum and roughing valves to a diffusion pump system. The main chamber is traversed by a ratchet-type conveyer which supports a holder 22 in which, for transport, the corners of the substrate 47 normally rests on lugs 51.  Centrally, below the conveyer, a mask 14 is held by a support 48 which, when the substrate is in position, is raised so that the lugs surrounding the mask pass through slots 50 in the holder 22 and the substrate is lifted from the lugs 51 on to the mask where it is positioned by flanges 36, 37. When deposition is completed in the chamber in question the substrate is lowered again on to the holder 22 and is conveyed through a vacuum unit to the next chamber. The Specification describes for illustration deposition of a capacitance/ resistance network on to a substrate where in the first deposition chamber the conductor pattern is deposited from a gold and chromium evaporation source, in a second chamber the resistors are deposited from a nickel-chromium alloy source and in the three remaining chambers the capacitors are formed by depositing in succession aluminium, a dielectric (such as silicon monoxide) and aluminium again.

Abstract: 1364634 Adaptive transversal equalizers PATELHOLD PATENTVERWERTUNGS-2 ELEKTROHOLDING AG 23 Sept 1971 [25 Sept 1970] 44441/71 Heading H4R In a transmission system incorporating a transversal equalizer a test signal comprising individual pulses of constant amplitude and irregularly changing sign is inserted in the transmitted signal, there being at least two communication pulses between each two inserted pulses. At the receiver a reference signal is generated, by evaluating the inserted pulses, and the reference signal is correlated with the input signal to the equalizer, or a signal derived therefrom, to obtain regulating voltages for the multipliers of the transversal equalizer. As described the inserted pulses are derived from a shift register with a logic circuit to provide a pseudo random binary stream and the communication signal is interrupted during the inserted pulse, space for the pulses being provided by time compression of the communication signal if desired. At the receiver a similar shift register and logic circuit RE, Fig. 6, can be synchronized with the incoming inserted pulses and fed, via a switch PS which is closed only during the inserted pulse, into a shift register R2. The signal Q at the tappings of the shift register is correlated with the signal at the output of the transversal equalizer IE and the result of the correlation fed to adjust the multipliers of the corresponding stages of the transversal equalizer IE. A signal level control circuit AR can also be adjusted using the correlator output V 0 , and if the low frequencies have been removed on transmission they can be restored by device UK. The system is applicable to a number of different transversal equalizer arrangements, i.e. to a feed forward or feedback equalizer; one where the equailizer is formed by shift register stages and the signal converted to digital form; where the same delay device is used for both the equalizer and the correlation circuit; and a system Fig. 7 (not shown) where the equalizer reduces cross talk between channels by cross coupling the channels.

Abstract: 1,030,157. Grabs for nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 26, 1964 [Nov. 26. 1962]. No. 44705/62. Heading B8H. An automatic grab comprises a weight member 2 supported within a casing 5 by a hoist cable 3 so as to be movable over a distance A relatively to the casing. Three grab fingers 6 pivoted at 7 to the casing 5 have extensions 17 biased by springs 8 against longitudinal slots 16 in the lower part 15 of the weight 2, whereby when the weight moves through the portion a of the distance A in the up direction relative to the casing the extensions 17 move over the ends 16a of the slots and the fingers 6 are moved from the open position. Fig. 2, to the closed position. Stop means are, however, provided to prevent this relative upward movement through the portion a except when the grab has been lowered on to a fuel element, in which case the fingers 6 close to engage the element. The stop means comprise a member 26 rotatable about a horizontal axis in the weight 2 and carrying at each end a pair of stops 27. The stops 27 co-operate with the lower ends of a pair of keys 9 fixed to the casing 5 when they are in vertical alignment as shown in Fig. 3, thereby preventing movement through the portion a. Rotation of the member 26 through 90 degrees to bring the stops 27 into horizontal alignment brings the stops clear of the keys. The member 26 is rotated by a coaxial cam 28 having four limbs 34 co-operating with a spring-loaded pawl 25 mounted on the casing 5 when the weight 2 moves down inside the casing. Three locking members 47 pivoted at 49 to the casing 5 are biased by springs 53 so that their projections 51 engage either an upper slot 52a or a lower slot 52b in the weight 2. When the grab is lowered to pick up a fuel element the parts have the positions shown in Figs. 2, 3 and shoulders 47b of the members 47 engage the bore of the fuel element channel in the reactor core to withdraw the projections 51 from the slots 52a. As the lowering movement continues the lower end 18 of the easing 5 engages the top of the fuel element so that on furthor lowering the weight 2 moves down within the casing and the member 26 is rotated through 90 degrees to move the stops 27 into horizontal alignment. Finally, the lower part 15 of the weight 2 engages the fuel element. Tension is now applied to the cable 3 and the weight moves through the whole distance A, movement through the final portion a causing the fingers 6 to close on to the fuel element. Moreover, the locking members 47 are released from the fuel element channel and the projections 51 engage the slots 52b to lock the fingers 6 in the closed position. In order to release the fuel element it is lowered into a storage facility having a bore similar to the fuel element channel.

Abstract: 1,139,964. Microcapsules. NATIONAL CASH REGISTER CO. 2 Oct., 1967 [28 Oct., 1966], No. 44721/67. Heading B8C. Microcapsules are produced by establishing an agitated aqueous system containing gelatine, one or more water-soluble, sulphonate-containing materials, adjusting the pH and temperature of the system to cause formation of a gelatine-sulphonate complex coacervate which is dispersed by agitation to form viscous liquid particles in the residual aqueous vehicle, and cooling the system to cause the disperse coacervate phase to deposit on and encapsulate particles of a core material (solid or liquid) previously dispersed in the system. The invention also comprises the treatment of gelatine-walled capsules formed by other coacervation techniques to cause dewatering by establishing an agitated dispersion of the capsules, adding thereto one or more watersoluble, sulphonate-containing materials and adjusting the pH to a value at which the capsule walls are dewatered. Suitable sulphonate-containing materials for both processes are alkyl-substituted and unsubstituted naphthalene sulphonic acids and alkyl benzene sulphonic acids and their watersoluble salts, salts of lignin sulphonates and water-soluble salts of phenol sulphonates.
