Abstract: 1,139,017. Speech recognition. INTERNATIONAL BUSINESS MACHINES CORP. 15 Sept., 1967 [29 Sept., 1966], No. 42164/67. Heading G4R. [Also in Division H4] In a speech analysis system, a signal representative of the harmonic energy of a speech signal is obtained from the sum of rectified signals each representing a respective harmonic content of the speech signal. Speech is split by filters at 3 having passbands of width 300 hz and centre frequencies as shown, the filter outputs being rectified at 4, passed through low-pass filters (15 hz) at 25 and summed at 29 to give the total spectral energy at 32. The outputs of filters 4 are also passed to 9 where they are summed, band-pass filtered (70 hz to 150 hz viz fundamental) at 13, fullwave rectified at 14 and low-pass filtered (15 hz) at 15, to give the harmonic energy at 16 (voiced sound). The energy signals at 32, 16 are compared at 17 to produce a voiced/unvoiced binary indication at 20d, the gains of the summing amplifiers 10, 30 being appropriately chosen for this purpose.

Abstract: 1,222,509. Bed warmers. THERMEGA Ltd., and W. J. JENKINS. 28 March, 1968 [24 April, 1967], No. 18834/67. Heading A5X. [Also in Division F4] A blanket or other flexible member 1 has an internal tube 2 connected to an external, liquid-filled chamber 4, the latter containing a heater 10 and a superposed thermosensitive device 9. Energisation of the heater causes liquid to be supplied to the tube until the liquid level falls below device 9; the latter then reduces or cuts off the energy supply to the heater. As shown, liquid from tube 2 passes to a chamber 5 which is connected by a oneway connection, e.g. a non-return valve 1, to chamber 4, so that as the pressure in the latter falls, due to the deenergisation of the heater, liquid is sucked back into chamber 4 and the cycle subsequently repeated. In a modification (Fig. 2, not shown) the ends of the tube are connected to separate chambers each of which contains a heater and thermosensitive device, so that the liquid passes through the tube alternately in opposite directions. Alternatively, one chamber is used and the opposite end of the tube is closed (Fig. 3, not shown).

Abstract: 1,225,182. Internal resistance heaters. S. J. POPEIL. 16 Feb., 1968 [16 Feb., 1967], No. 7762/68. Heading H5H. An electrically heated steaming chest for steam-heating hair curlers comprises a box-like base having a hinged lid (see Fig. 2, not shown), the base enclosing inner walls 62 and 64 which form a steam-generating compartment containing the heater electrodes. The front wall has a water-metering slot 66 which communicates with a condensed water reservoir 65 formed between the inner walls 62, 64 and the walls of the base. A perforated tray for curlers is mounted on top of the steam compartment. The internal resistance heater assembly 40 consists of two interleaved U-shaped electrodes 41 and 42 having vertically orientated parallel sides defining three separate opposed plate areas between which the current passes. The ends of the electrodes are twisted through 90 degrees at 46 and have a bore 44 for mounting within the steam compartment by screws 72. The screws enter water-tight bushes 71 having a threaded blind hole containing a wire coupler. The free ends of the electrodes are supported by slotted locaters 94 upstanding from and integral with the compartment bottom 69. The chest has a false bottom 85, and the wires from the couplers 71 pass between this bottom and the undersides of the steam compartment and reservoir to an inlet port at the back of the chest (see Fig. 16, not shown). The lead is secured at this point by a labyrinth lock which encloses the power cord where it bifurcates into the electrode leads; this lock consists of a W-shaped wall interlocked with a V-shaped wall, both walls having inwardly projecting lugs which engage with and trap the wire (see Fig. 17, not shown). For use, the power cord 75 is plugged into a wall socket and water is poured through the perforated tray into the reservoir and steam compartment. When the water boils, hair curlers are placed on the tray and the lid is closed; steam condenses on the lid and the water returns to the reservoir and thence through the metering slot to the electrodes. To improve the electrical conductivity of the water, a charge of baking soda may be added, an appropriate amount of which may be measured out in a depression provided for this purpose in the end of each hair curler (see Fig. 21, not shown).

The non-linear shape of the current voltage characteristic of the emitter-base junction of a transistor 3 operating as a detector, is compensated by supplying the input signal 1 to the base through a diode 2 biased by a resistor 4, the output circuit including a filter 5, 6. The transistor and diode are matched as closely as possible, either by selection of a resistor 4 to give an appropriate current flow in the diode, or by using as the diode the emitter base junction of a further, identical transistor (3<SP>1</SP>, Fig. 2, not shown). Diodes (2,2<SP>1</SP>) may also be included in the emitter circuits of the twotransistor arrangement to increase the magnitude of signal which may be safely handled.

In a process of injection moulding plastics materials the displacements of a movable part of a mould, forming part of the mould cavity, and of one or more injection pistons are each effected by a fluid delivered by one or more pumps, and during at least a part of the moulding cycle the velocities of said movable part and of said piston or pistons are controlled in accordance with a pre-determined velocity programme. The fluid which effects the displacement of the mould part, piston or pistons, may be controlled so as to secure the predetermined velocity programme throughout at least 90% of the displacement and then subjected to a programme of controlled pressure throughout the final part of the displacement. Electrical closed loop servo-control circuits may be used in which a comparator receives a reference signal from the predetermined velocity programme and a response signal representative of the actual displacement and provides a current proportional to the difference between the signals to thereby control the displacement.

Abstract: 1,266,034. Television; cathode-ray tube operating circuits. ENGLISH ELECTRIC VALVE CO. Ltd. 9 June, 1969, No. 29094/69. Headings H4F and H4T. [Also in Division H1] An image pick-up tube arrangement, especially for detecting infra-red images, comprises a tube with a pyro-electric (i.e. photovoltaic) target 2 on which the image 9 is projected through interrupting means 10 adapted to block the light for periods S, Fig. 2, of about 0À1 second; and means are provided for scanning the target at a period A of about 0À02 second near one end of the interruption period with a low velocity beam to produce cathode potential stabilization, and at a period B near the other end of the period with a high velocity beam to produce anode potential stabilization and a uniform potential distribution across the target. Preferably, as shown in Fig. 2, the B period is followed by a second A period as this produces better results, but an output signal is obtained only during the first A period. The ON and OFF periods O and S may be opposite to those shown in Fig. 2 (Fig. 3, not shown). The target 2 may be of tryglycine sulphate, lithium niobate, sodium nitrate or strontium barium niobate, and the output may be derived from a signal plate 5, as in a vidicon, or from a returning beam as in an image orthicon. Operating circuit.-Rotation of the shutter disc is controlled by a master timing circuit 13 which controls a further timing unit 14 adapted to produce the pulses A and B. These are fed to the electron gun 3 as " bright-up " pulses, control the gate 20 for the output signals, and also control the potential source 18 which supplies operating potentials to the tube. For the low velocity beam operation, zero potential may be applied to the cathode and target electrode and a pulse of 300 V. to the field mesh 4; alternatively the cathode may be at zero potential, the field mesh at 300 V., and the target is pulsed down to zero potential. For high velocity beam operation zero potential may be applied to the field mesh and target, and the cathode may be pulsed to -300 V.; alternatively, the cathode may be at zero potential and 300 V. may be supplied to the field mesh and to the target.
