Abstract: 1,226,614. Colour television tubes. SONY CORP. 8 July, 1968 [10 July, 1967; 12 July, 1967], No. 32444/68. Heading H1D. In a colour television display tube in which a plurality of beams B B , B G  and B R  lying in a common plane intersect at the centre of the main focusing lens L and are converged laterally to a common point at the colour selection grid or shadow mask Gp by a system F which, as shown, comprises a centre pair of shielding plates P, P<SP>1</SP> and an outer pair of deflection plates Q, Q<SP>1</SP>, a coil 16 is provided to generate an axial flux in the vicinity of the lens L in order to effect a twisting displacement of the outer beams B B , B R  about the axis of the system. By this means vertical misconvergence of the beams at the screen may be corrected, such misconvergence being due, e.g., to mechanical twist of the plane in which the beams are emitted, to spherical aberration of the deflection yoke D, to various other mechanical errors, or to the effect of the earth's magnetic field. Static vertical misconvergence is corrected by supplying current to the coil 16 from an adjustable D.C. source 17; dynamic vertical misconvergence is corrected by supplying to the coil 16 from source 18 saw tooth waves synchronized with the horizontal and vertical sweep signals applied to the deflection yoke. Dynamic horizontal misconvergence is corrected by applying a dynamic convergence deflection voltage synchronized with the horizontal sweep signal across the plates P, Q and P<SP>1</SP>, Q<SP>1</SP> of the convergence system F. Lateral shift of the beams B R , B B  due to the earth's magnetic field may be corrected by a ring magnet 22 having two oppositely wound, series-connected coils connected to an adjustable D.C. source 25. The magnet 22 and the coil 16 may be included in a coil assembly having an insulating support 28, Fig. 9, provided with radial flanges 32, 33. Coil 16 is wound between flanges 32, 33 and the core of magnet 22 is formed in two halves 23a (23b), each half having end holes for receiving support pins 36 projecting axially from flange 33. All the beams may be laterally shifted by a further colour purity magnet 40, Fig. 1, similar to the magnet 22. The magnet 40 is mounted on screws (49, Fig. 11) extending through an end flange (45) of the deflection yoke assembly D. The magnets 16, 40 may be constituted by rotatable permanent ring magnets.

Abstract: 1,227,095. 227, 095. Sensing temperature. INTERNATIONAL BUSINESS MACHINES CORP. Sept.22, 1969 [Oct. 15, 1968], No.46505/69. Heading G1D. [Also in Divisions F4 and G3] A fluidic temperature sensing device for use in a cooling system, comprises a chamber 16 into which a stream of cooling fluid is directed from a nozzle 12, the chamber having a wall 18 of good thermal conductivity which diverges from the direction of undisturbed flow of fluid from the nozzle, the stream adhering to the wall 18 until it reaches a given temperature when it will become detached from the wall 18 and impinge on a wall 20 which sets up turbulence causing the stream to return to the wall 18, the net result being that below the given temperature the flow will be along the wall 18 to a channel 24, and above the given temperature oscillation of the fluid stream between positions of adherence and non-adherence to the wall 18 will occur. The wall 18 may be comprised of components 19 to be cooled, the device then giving an indication if the temperature of these devices rises above a desired limit. Alternatively the device may be simply used as a temperature sensor, the temperature of the wall 18 controlling the device. A control port 21 is provided and in an alternative embodiment the wall 20 is replaced by a feedback channel leading to a point opposite the port 21. It has been found that with the wall 20 the frequency of oscillation is not fixed, but with a feedback channel, the frequency is determined by the length of the channel. Also, increasing the length of the wall 18 increases the temperature at which detachment of the fluid stream occurs.

Abstract: 1,230,144. Data storage. ADDRESSO-GRAPH-MULTIGRAPH CORP. 19 June, 1968 [20 June, 1967], No. 29310/68. Headings G4C and G4M. A series of characters sensed from a card is entered in a shift register, each stage of which e.g. 101-107, stores a character, the number of stages being greater than the number of characters sensed from each card, a shift pulse is generated each time a character is entered, and data is shifted through the register by clock pulses after the entry of data from each card, the total number of clock shift operations being counted as a check on the entry of data and the operation of the shift register. Clock source 46 operates continuously to supply pulses from multivibrator 352 through gate 139, one-shots 138, 141 to shift lines 311- 317. On feeding of a card, one-shots 131, 135 are triggered to generate start codes, and 355 is reset to close the clock gate 139. One-shot 136 is triggered by the setting of 131 and again subsequently when 135 resets so that two shift pulses are produced for entry of the codes defined by the connections from triggers 131 and 135 combined and trigger 131 alone. As each card character is sensed, a parity check is made as described in detail in Specification 1,224,923 and multiple attempts at sensing are made if parity is not correct. The correct parity signal sets trigger 136 through OR gate 125 to shift in a correctly sensed character via OR gates 91-97, but no entry or shift occurs when parity is incorrect. At the end of a card sensing cycle, trigger 133 is set to enter an end code, and subsequently 354, 355 are set to open clock gate 139. The clock pulses advance the data through the shift register and step the counter via gates 388, 389. For the correct number of characters, the start code should enable gate 49 at the same time that gate 381 is enabled by message length switches coupled to the counter, whereby 383 is set and gates 388, 139 are closed, a shift and counter pulse is however produced by 351, 138. As each code is utilized by an output device e.g. a printer, contacts RE6-1 are closed to trigger 351 again for the next character shift and count. When the end code is detected by gate 48, gate 362 is enabled, provided the correct counter state is concurrently detected by gate 363, 372 is set and 383 is reset to re-open gate 388, and a fresh card cycle is initiated, Fig. 4 (not shown). Error signals are generated if the counter is not in the correct state when the start and end codes are detected. If, owing to parity errors or malfunction of the shift register entry circuits, the number of characters entered is incorrect, the start code is detected by gate 49 before gate 381 is enabled, so that 383 is not set, and shiftt and count pulses continue to pass through gates 139, 388. When gate 363 is eventually enabled, gate 377 is opened and read error flip flop 378 is set. If gates 49, 363 do not produce simultaneous outputs, gate 366 sets punch error flip flop 371.

Abstract: 1,250,276. Reactive current and volt drop compensation. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 20 Feb., 1969 [21 Feb., 1968], No. 9145/69. Heading H2H. [Also in Division G3] The reactive current or volt drop in an A.C. mains is compensated by capacitors or inductors which are varied step wise by thyristors, the variable total current of a load connected to the mains being used to detect its reactive current component at the beginning of each total current half wave and the compensating current being matched to the reactive current in the same half wave. The reactive current of the inductive load LR may be maintained constant at a desired value (zero or finite) by opposing it with a capacitor current of opposite sign or supplementing it with an inductive current, the respective effects being to remove the reactive current fluctuations above the desired value or to supply the fluctuations below the desired value. If volt drop compensation is desired, the compensating current may be greater than that for reactive current compensation, depending on whether all or only some of the volt drops occurring in the mains are to be compensated. In the described embodiment the inductive load LR is compensated by capacitors Cl, C2, C3 controlled by anti-parallel thyristors whose firing pulses are obtained from a control circuit comprising members Q st , M st  and St. From a mathematical analysis of the waveforms of mains voltage U, total load current I, reactive current component and capacitor current, Fig. 1 (not shown), it is explained that the reactive current component is dependent on the product of the phase angle between U and I and the rate of rise of I at the start of each half cycle. Thus in Figure 2 a current transformer W detects the current I and supplies a signal to the member Q st  which obtains the angle between U and I, for example by obtaining the time difference between zero passages of U and I using saturable reactors delivering spaced voltage pulses which are counted digitally. The rate of rise of I is obtained by a mutual inductance M and this signal, together with the output signal from member Q st , is fed to member M st  which forms the product of the two signals as an ouput signal used to control the member St. The instantaneous value of I just before switch-on of the capacitors may be used to obtain the rate of rise.

Abstract: 1,256,702. Reactor power plant. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 Feb., 1969 [7 Feb., 1968], No. 6169/68. Heading G6C. In a power plant in which gas coolant heated by a reactor flows to a utilization facility in a closed circuit, a proportion of the gas is heated in the reactor to a temperature higher than that required by the facility, the remaining proportion either being not heated by flowing in a circuit by-passing the reactor or being heated in a cooler part of the reactor core to a temperature lower than that required by the facility. This cooler part may be the fertile blanket of a fast breeder reactor. The two streams are mixed on the outlet side of the reactor to form a stream having a temperature suited to the utilization facility. This division of the gas flow into two streams reduces the power required for pumping the gas since only a proportion of the gas flows through the high impedance, high temperature part of the reactor core, the remaining proportion flowing through a path having a relatively low impedance. Three embodiments are described with reference to Figs. 1-3, not shown.
