Title: Improvements in electric switches having arc preventing or limiting arrangements
IPC: H01H33/04
Filed: 1936-08-05
Abstract: 479,069. Liquid - break switches. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. Aug. 5, 1936, No. 21544. [Class 38 (v)] In a switch in which on separation of the contacts a current flow is established through a path of electrically - conductive liquid, the circuit is finally interrupted by mechanically dispersing the liquid. In the construction shown the hollow movable contact 1 is carried by a piston 4 movable in a cylinder 5. To open the switch, water or other conductive liquid under pressure is admitted from a tank 9 to the lower side of the piston through a pipe 7 ; the piston is forced upwards, carrying the contact 1 away from the fixed contact 2, and at the same time a jet of liquid is forced from the upper-part of the cylinder 5 through the contact 1 on to the contact 2. As the movable contact 1 approaches its upper position, a rod 6 nearly closes the aperture at the end of the contact, and causes the dispersion of the liquid in the form of a spray. The switch is closed by admitting liquid under pressure from a tank 9 to the upper side of the piston through a pipe 8. In a modification, upper and lower fixed contacts are connected by a hollow movable electrode, the lower contact being mounted on insulating means above a collecting vessel. The electrode is formed at its upper end with a piston which slides in a cylinder connected with a liquid reservoir at some height above the switch. A pump is provided for delivering liquid from. the vessel to the reservoir. Adjacent the upper fixed contact is a diffuser nozzle connected to a source of air under pressure. To open the switch, a valve is opened to allow water to flow from the reservoir through the electrode, and simultaneously the latter is drawn upwards. When the electrode leaves the lower contact, the circuit is maintained through the liquid until the latter is dispersed by admitting compressed air to the diffuser nozzle. The Provisional Specification describes another arrangement in which an iris diaphragm gradually reduces the cross-sectional area of the liquid column until the flow of liquid is interrupted.

Title: Improvements in evaporative cooling systems for engines and other machines, especially for aircraft engines
IPC: F01P3/22
Filed: 1935-07-29
Abstract: 456,385. Cooling systems for engines &c. HEINKEL, E., 15, Seestrasse, Warnemunde, Germany. July 29, 1935, No. 21558. Convention date, July 28, 1934. [Class 29] In an evaporative cooling system for aircraft or vehicle internal combustion engines, turbines or other power units, having a throttling device b located between the cooling jacket &c. a and an evaporator or reducedpressure vessel c where vapour forms, an auxiliary evaporator t is provided which comes into use when the engine is inverted, as for example in flying, so that the jacket &c. is at all times flooded. The throttling device may be a valve or nozzle, and may maintain the liquid space at above atmospheric pressure and the vapour space at atmospheric or below. The liquid from vessel c returns by gravity to the jacket inlet e and the vapour passes through a non-return valve f to a small capacity condenser g which is connected by a pipe h to a vessel i provided with condensate and air pumps k, s, the condensate being returned to the jacket inlet. In the case of large engines the capacity of the condenser can be kept small by employing a vapour compressor l, driven by a motor m, to super-heat the vapour and promote rapid condensation, the compressor being arranged in a valved byepass pipe. The flow of cooling air over the condenser may be controlled by a flap r adjusted by a device q, o, in accordance with the pressure on the discharge side of the condenser. Alternatively the condenser may be movable into and out of the air stream. The evaporator t is located at the end of a pipe u connected between vessel c and the jacket inlet, and a pipe u<1> connects the upper part of the condenser with the receiver i, which, with its associated pumps, may be cardan suspended.

Filed: 1931-07-31
Abstract: 382,672. Integrating. KENT, Ltd., G., 199, High Holborn, London, and GRAY, F., Biscot Road Works, Luton. July 31, 1931, No. 21950. [Class 106 (iv).] Variable-speed friction gearing adapted for integrating comprises a sphere 1, Fig. 1, in contact with three rollers two of which, the rollers 2, 3, turn on fixed colinear axes while the third, the roller 4, is mounted so that its axis can be angularly displaced to alter the position of the axis of rotation of the sphere. The speed at which the roller 3 is driven depends jointly upon the speed of the driving roller 2 and the inclination of the control roller 4. As applied to integrating the product of the travel of a rope and the tension, the roller 2 is driven at a speed proportional to the travel and the roller 4 is displaced according to the tension, so that a counter driven by the roller 3 indicates the work done by the rope. If again the roller 2 be driven by a clock and the axle 7 of the roller 4 be displaced by a device measuring the rate of flow of fluid in a pipe, the motion of the roller 3 would measure the quantity of fluid passed. Increased traction friction may be produced by a further spring-pressed roller 20, Fig. 3, thrusting the sphere 1 down on the rollers 2, 3, shown end-on. The tilting control roller 4 is shown duplicated at 4<1> and supported in a rocking frame 17.

Patent GB-225185-A (GB)
Abstract: 225,185. Compagnie des Forges et AciÚries de la Marine et d'HomÚ- court. Nov. 21, 1923, [Convention date]. Sights and methods of sighting.- Relates to apparatus for determining the azimuth, height, and horizontal distance of an aerial target. According to the invention, a range-finder A of the coincidence type, adapted to give the height of the target directly, is combined with an instrument B of known type which measures the horizontal distance, the rotations in azimuth serving for both instruments. The rotation of the range-finder A about an axis 9 by a handwheel 10 operated by one observer, gives, when coincidence is found, the height directly on a scale 11 and imparts a displacement to a pointer 12. Another observer operates a wheel 6 to set a block 4 on a screw 5 for the observed height and also operates a wheel 7 to move vertically a block m carrying the screw 5 and thereby rotate, a bar 3 about the axis 9 to bring a pointer 13 into register with the pointer 12. The motion of the block m, thus effected, is transmitted by a band 8 to an apparatus on which is set up the horizontal distance of the target. The Specification, as open to inspection under Sect. 91 (3) (a), also describes the following improvements in the apparatus covered by Specification 205,801. (1) The graduations on the alidade and ruler are arranged in a sequence of five colours to facilitate bringing the same graduations into coincidence, (2) the coincidence is observed by a horizontal periscope on the alidade, and (3) the azimuth dial has two pointers geared in a similar manner to the hands of a clock for communicating azimuth angles to the gun as " time of day." This subject-matter does not appear in the Specification as accepted.
