Abstract: 1302771 Coating plastics film NISSHIN BOSEKI KK 3 July 1970 [11 July 1969 2 March 1970 8 June 1970] 32357/70 Heading B2E A process for producing coated plastic film, the film being soluble or swellable in dimethylformamide, comprises forming a solution of a resin which is soluble or swellable in dimethylformamide, a plasticizer for the resin, an inorganic fine powder and dimethylformamide, applying the composition as a coating to the film, treating the coated film with water to coagulate the composition and subjecting the coated film to heat treatment so as to soften the coating without thermal deformation of the film. Suitable films are vinyl polymer, or copolymer, a polycarbonate, 8-nylon or a cellulose plastic. Preferred films are of polystyrene, styrene-butadiene copolymer, styrenebutadiene-acrylonitrile copolymer, styreneacrylonitrile copolymer, polyvinyl chloride, vinyl chloride-vinylidene cloride copolymer and a vinyl chloride-vinyl acetate copolymer and the film may be uniaxially or biaxially oriented or unoriented. Numerous suitable plasticizers are specified as well as inorganic powders, such as calcium carbonate, zinc oxide, kaolin and clay. The heat treatment may be effected with hot air, infra-red heating, roll heating or high frequency induction heating, or, preferably with hot water or steam. The hot water treatment may be conducted at any desired stage after the coating and it is preferred that this be effected just after the coating step since it also coagulates the surface. The coating composition may be of styrene homo- or copolymer, e.g. polystyrene and styrene-acrylonitrile copolymer. Application may be of roll, airknife or curtain coating.

In a haymaking machine of the type wherein ground-driven rake-wheels 15 are arranged obliquely to the line of travel A of the machine, fixed baffles 16 are mounted so as to receive the crop displaced by the rake-wheels, the arrangement being that the crop is both laterally displaced and laterally compacted by the passage of the machine. As shown, the machine frame 10, 11, 12 is provided with an A-frame for attachment to the power lift of a tractor 13 and has two crank-supported rakewheels 15 discharging crop against a vertical baffle 16 formed either of sheet material or of tines. The baffle is pivoted about a vertical axis 17 and loaded by a spring 19 against deflection. A second frame may be pivoted to the first about a horizontal longitudinal axis and be pivotable into a raised inoperative position (Fig. 3, not shown).

Title: Propellent shut-off valve for a rocket engine
Inventor: HUNT MICHAEL STANLEY
IPC: F02K9/56
Filed: 1963-08-16
Abstract: 1,008,158. Rocket propulsion. BRISTOL SIDDELEY ENGINES Ltd. Aug. 12, 1964 [Aug. 16, 1963], No. 32479/63. Heading F1J. The invention relates to a shut-off valve which is disposed in a propellant supply line of a rocket engine between a propellant pump and a burner assembly. A propellant supply system is shown in Fig. 1 and comprises a turbine F driving a Fuel pump A and an oxidant pump K, the fuel supplied by the pump A passing through the line C, through the shut-off valve G to the burner assembly D of the rocket combustion chamber E. The shut-off valve is shown in Figs, 3 and 4 and comprises a fuel inlet 6 and a fuel outlet 7. The valve casing 1 affords a pair of valve seats 2 and 3 with which co-operate respectively valve members 4 and 5, the arrangement being such that when one valve is open the other is closed. The valve 4 controls flow of fuel from the inlet 6 into the chamber 8 from which fuel flows through a non-return valve 20 to the fuel outlet 7. The valve 5 controls communication between the chamber 8 and the vent 9 so that when the inlet valve 4 is closed, the caamber 8 is connected to the vent 9 through the open valve 5. When the rocket is being started, steam under pressure produced by decomposition of hydrogen peroxide in the burner assembly D is supplied to the inlet 16 of the valve casing 1 and the steam pressure acts on piston 12 integral with the valve member 5 so as to close the valve 5 on the seat 3 against the action of the spring 11 so that the vent 9 is now closed off. A stem 15 integral with the valve member 5 at the same time acts against the valve member 4 which is thereby opened against the action of spring 10. The fuel passes into chamber 8, opens the non-return valve 20 against the action of spring 21 and passes through outlet 7 to the burner assembly D. A further non-return valve J is fitted to the valve casing 1 at 22 so that when the engine is shut down, nitrogen under pressure may be passed into the chamber 23 downstream of the valve 20 to purge the system. A bleed valve H may be also provided in the line C, the valve member 25 being normally biased to the open position by the spring 31, but closing as soon as fuel under pressure passes into the line.

Title: Improvements relating to Oscillator Circuit Arrangements

Abstract: 1,157,691. Electric timepieces. R.W. REICH. July 20, 1966 [July 26, 1965], No.32561/66. Heading G3T. [Also in Division H3] In an oscillator circuit for clocks having two complementary transistors 1, 5 each having its emitter connected to a different supply terminal, a resistor-capacitor timing circuit 7, 8 and 6 is connected to cause the transistor 5 to conduct when the voltage across the capacitor has reached a predetermined value, this causes the transistor 1 to conduct to produce an output pulse in a collector coil 2, the timing circuit is responsive to conduction of the transistor 1 to cut-off both the transistors and end the output pulse and means is provided to limit the maximum voltage of the output pulses to a predetermined magnitude. As shown the output pulse is limited by a Zener diode 11. Also the charging voltage for capacitor 6 may be stabilized by a Zener diode 12. Resistor 8 provides variation of the oscillator frequency and the resistors 7 or 9 may have negative temperature coefficients as may a resistor which can be connected in parallel with the capacitor 6 so as to reduce the effect of temperature on the circuit. The resistors 3, 9 may be replaced by diodes 4, 10, alternatively resistor 9 may be replaced by a capacitor to alter the conductive and non-conductive periods of the transistor 1. The oscillator may be connected to an A.C. supply and may oscillate at a frequency lower than the supply. The circuit may be connected to a high voltage supply by including suitable resistors in the base and collector leads or by supplying the circuit from a tapping on a voltage divider connected across the high voltage supply. A capacitor may be connected across the coil 2 to prevent self oscillation. The oscillator may provide timing pulses, drive on impulsing mechanism of a timer having seconds and minute and hour wheels or activate relay operated controls.

Abstract: 322,312. Soc. Anon. Servo-Frein Dewandre. Oct. 6, 1928, [Convention date]. Fluid-pressure.-The supply of fluid to a relay applicable to brakes of vehicles and hauling engines, and actuated by compressed air or vacuum is controlled by two electromagnetic valves operated in succession to apply the power fluid or to stop the application when the required motion has' been effected; the device is operable by hand when power fails. Movement of the lever 6 by the operator brings a contact 11 into contact with a blade 8 and completes a circuit through an electromagnet 4 which then closes an air valve 3. Further movement brings the blade 8 into contact with a contact 12 on a lever 7 connected with the piston 9 and with the load 20, which may be the trap door of a silo, or a brake or clutch. The circuit through the electromagnet 5 is thus closed and the valve 2 raised putting the cylinder 10 under vacuum and causing the piston 9 and lever 7 to move with the lever 6. If the vacuum fails, the operator moves the load through the levers 6, 7 by his own physical strength.
