Title: Improvements in or relating to selective gate circuits
Inventor: SHEARME JOHN NOEL
IPC: H03K17/62
Filed: 1964-04-30
Abstract: 1,058,277. Selective gate circuits; vocoders. MINISTER OF AVIATION. April 29, 1965 [April 30, 1964], No. 17985/64. Headings H4R and H3T. [Also in Division G4] The input to the emitter of a transistor can be inhibited by one or more inputs of greater amplitude applied to the base through separate unilaterally conducting devices such that the current from the inhibiting inputs flows through the base resistor in the same sense as the base current of the transistor. An array of such circuits can be used to analyse a speech waveform into its formant frequencies. In Fig. 2, the waveform is applied to a number of bandpass filters (not shown) whose outputs I1-I5 are taken to the emitters of transistors T1-T5. Each transistor has applied to its base the output(s) of the adjacent filter(s) so that an output is obtained at O1-O5 if the corresponding frequency band is present in the waveform at a greater amplitude than the adjacent frequency bands. The bands are chosen so that formants are thereby identified. Batteries or diodes may be included in the input leads to provide threshold levels. NPN transistors may be used with reversal of the diode polarities.

Title: Improvements relating to materials for use in rendering sea water potable
IPC: B01J39/02
Filed: 1950-07-20
Abstract: In a dry material suitable for use in rendering sea water potable and having as its principal ingredients a powdered or granular cation-exchange material having exchangeable silver ions and one or more oxides or hydroxides of a metal capable of reacting with either dissolved sulphates or dissolved chlorides to produce substantially insoluble sulphate or chloride, e.g. barium or silver, the area of contact between the exchange material and the oxide or hydroxide is kept as small as possible and not more than 150 square cms. per gram of the total oxide or hydroxide. The material is preferably in briquette form and the oxide or hydroxide is incorporated in it in the form of one or more pellets, or in the form of coarse particles, or in the form of a coated powder.  The coating should be heat-stable, water-soluble and non-toxic, and may be applied also to the cation-exchange material.  Examples are gelatin, starch, or sugar.  The exchange material is preferably silver alumino-silicate. The incorporation of the oxide or hydroxide as one or more pellets is particularly suitable when the amount is small, say 5 per cent of the total.  Other ingredients may be mixed with the exchange material or with the oxide or hydroxide before the briquettes are formed.  A disrupting material, e.g. bentonite, should be incorporated in the pellets as well as in the exchange material to ensure quick dispersion on addition to sea water.  Specification 577,449 is referred to.
Patent GB-793961-A (GB)
Title: Dough handling machine
IPC: A21C7/01
Filed: 1955-06-23
Abstract: 793,961. Dough-moulding machines. UNION MACHINERY CO. June 23, 1955 [Aug. 11, 1954], No. 18209/55. Class 87(2). Dough in a hopper 86, Fig. 5, pivotally mounted at 90, is sucked by vacuum into cylinders 28 in a rotating drum 22. (For stiff doughs, the hopper may be closed and pressurized). As the drum rotates, a roller 60 engages a cam edge 65 causing a gear segment 52 to rotate moving a rack 42 and a double-ended piston 30 upwardly in each cylinder to define the volume of the dough receiving chamber and force out any excess dough. The volume is adjusted by releasing a screw 72 and moving the cam 65 across a scale 76. A knife 95 severs the dough in the hopper from that in the cylinders. A baffle plate (see Fig. 6, not shown) in the hopper supports the dough to make the pressure of the dough on the dough in the cylinders independent of the head of dough in the hopper. It also acts to compress the dough against the drum and to prevent the dough from being churned up. As the filled cylinders leave the hopper, the cam roller 60 engages a cam 200 to cause the piston 30 to move downwardly and expel the dough. Suction is also applied to assist in removal of the dough. The suction also removes dough from suction ports and passages in the pistons. Stationary wires 202 remove dough from the tops of the pistons. The dough contacting surfaces of the drum and pistons are lubricated by oil pumped to a distributer 218, Fig. 1, which delivers it to feed pipes 216, 226 (see also Fig. 4, not shown). The dough pieces discharged from the cylinders fall onto a belt 234 where they are rounded beneath concave boards 266 which are arranged at an angle to the longitudinal axis of the belt. The boards 266 have a lining of polytetrafluoroethylene and are adjustably supported by rods 270. The rounded balls are removed from the belt by a cage 275 consisting of discs 276 joined by rods 280. The balls are floured as they travel down a shoot 292 by a flour duster F. Baffles are provided in the shoot to give the balls a zig-zag course.

Title: Improvements in or relating to gyroscopic systems
IPC: G01C19/38
Filed: 1925-07-18
Abstract: 365,188. Gyroscopic apparatus. MEREDITH, F. W., Royal Aircraft Establishment, South Farnborough, Hampshire. July 18, 1925, No 18389. [Class 97 (iii).] A gyroscopic system comprising a rotor and two gimbal rings and having the rotor axis vertical or horizontal, is provided with a gravitational control comprising a pendulum mounted on a single axis of oscillation and carrying nozzles for causing blasts of air to act on the rotor ring to erect the said ring or the other ring. The system is primarily intended for use on aircraft in connection with automatic control or for other purposes. The Figures show an arrangement in which the gyroscope 1 is mounted on an aero plane 3 with its axis vertical within a vertical ring 4 which is pivoted about a longitudinal axis 5 in a horizontal ring 6, the ring 6 being pivoted about a transverse horizontal axis 7 on the aeroplane. The gravitational control for erecting the ring 6 comprises a pendulum 9 mounted on the axis 7 and having an extension 10 carrying nozzles 11 which are supplied with compressed air and are directed towards opposite sides of a vane 12 carried by the ring 4. Tilting of the gyroscope relatively to the pendulum about the axis 7 causes the forces on the two sides of the vane to become unbalanced, the resulting torque about the axis 5 causing the gyroscope to precess about the axis 7. To maintain the rotor axis 2 at rightangles to the axis 7 an antitopple system is used comprising a piston valve 13 associated with the rings 4, 6 so as to detect relative movement between them, and nozzles 14 controlled by the valve and associated with the ring 6 for applying a torque thereto so as to precess the ring 4 to its normal position. Specification 365,186 is referred to.

Abstract: 812,356. Continuous-casting machines. STOKOWIEC, Z., KOSARSKI, Z. Z. J., and SHEEPBRIDGE ALLOY CASTINGS Ltd. Sept. 24, 1956 [June 24, 1955], No. 18394/55. Class 83 (1). A method of casting non-ferrous bars, tubes, &c. comprises gravity - feeding molten metal into one end of a die which is heat-insulated, whereas the other end of the die is at a temperature to cause the metal to solidify, and applying step-bystep movement to the solidified metal so that there is a stationary period and a movement period, controlling the rate of the step-by-step movement and the rate of the extraction of heat so that the skull, which is formed in the heat-insulated end of the die during the stationary period, is 'broken down during the movement period when further molten metal enters the die under gravity. A holding furnace 11, Figs. 1 and 2, comprises a die-holder 13 of graphite, copper or copper-alloy, and having a water jacket 14 at its outlet end. The cast bar 6 is extracted by rollers 20-23 driven by an electric motor, started and stopped at intervals, e.g. by a clockwork mechanism or by means responsive to the temperature of the casting. The bar may be additionally cooled by water sprays adjacent the outer end of the die. Hollow sections may be cast by inserting a graphite mandrel 37 in the graphite die 38, Fig. 5. In a modification, a crucible is supported within a heating chamber, the die-holder extending through the walls of both. In a further modification, Figs. 6 and 7, the step-by-step movament of the casting is imparted by an hydraulic motor 42, which reciprocates a carriage 45 running on rails 47. On the carriage is mounted an hydraulic gripping device comprising jaws 50 actuated through linkwork by a pneumatic motor 60. The motors 42, 60 are provided with changeover valve mechanism controlled by a clockwork timer, so that after a predetermined time of solidification in the die, the motor 60 closes the jaws 50 on the bar, and the motor 42 causes the carriage to move away from the die, drawing the solidified metal therefrom. After a predetermined length of movement the valves are actuated by a knock-off plate so that the jaws 50 open and the carriage returns towards the die for the next operation, determined by the clockwork mechanism. The step-by-step motion may be controlled by the variation in temperature of the bar by the use of a thermo-couple.
