Title: Improvements in or relating to radio systems for the location of aircraft, ships andother targets
IPC: G01S7/12
Filed: 1947-06-02
Abstract: 646,141. Radiolocation. SADIR-CARPENTIER. June 2, 1947, Nos. 14601 and 14602. Convention dates, Aug. 31, 1939 and Dec. 18, 1939. [Class 40 (vii)] In a pulse radar system employing a cathoderay tube display, the receiving portion comprises a directional aerial which is continuously rotated, a saw-tooth time-base generator synchronized by pulses received directly from the transmitter and producing a radial deflection of the cathode-ray beam, means for intensity-modulating the beam with received echo signals, and means for rotating the radial trace about the centre of the cathode-ray tube screen in synchronism with the rotation of the aerial. In a system described for the purpose of explanation only, incoming signals are received upon a frame aerial 15, the output of which is amplified and detected at 7 and then applied to the grid 18 of the cathode-ray tube 9. The signal received directly from the transmitter 1 is used to synchronize saw-tooth generator 11, the output of which is applied to the deflecting coils 19, 19<SP>1</SP> which are rotated about the tube in synchronism with the aerial rotation. Each reflecting object produces on the display a circle concentric with the centre of the screen, having a radius corresponding to the range, and having a pair of diametrically opposed breaks corresponding to the nulls of the frame aerial and indicating the direction of the reflecting object. The invention, Fig. 3 (not shown), provides an arrangement dispensing with the movable deflecting coils. A search-coil rotating in synchronism with the aerial and fed with the saw-tooth deflecting voltage is coupled to a pair of stator coils arranged at right-angles, the outputs from the stator coils being taken to two sets of deflection coils disposed orthogonally about the cathode-ray tube. A narrow beam directional aerial system having a single main lobe may be used in place of the frame aerial to produce a P.P.I. display.

Title: Improvements relating to the cleaning of pipe systems and other supply, storage, and conduction systems for drink liquids
IPC: B08B9/02
Filed: 1939-05-16
Abstract: 528,876. Cleaning beverage-supply systems. WITTEL, K. F. May 16, 1939, No. 14608. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 25, 1939.] [Class 91] [Also in Group XXVIII] A pipe system b or other closed vessel forming part of a system for supplying beer or other beverage is cleaned by means of alcohol which is forced through the system from a tank 1 by a pump 2 and returned to a tank 3 in which it is evaporated to recover the pure alcohol, which is condensed in a coil 21 and returned to the tank 1. A door 30 enables the deposited residue to be removed. Water is mixed with the alcohol to prevent the formation of an explosive mixture at the end of the evaporation process. The tank 3 is heated by an electric heater element 12 which may be switched on by a switch 11 when the pump 2, which is a diaphragm pump operated by an alternating-current magnet, is switched off. The element 12 is switched out by a thermal device 40 when a lamp 43 indicates that this has occurred; a second lamp 42 is connected across the electric supply main c. Water supplied through a pipe 13 passes around the coil 21 to a tank 5 adjacent the element 12 so that it is heated simultaneously with the alcohol and may be used to flush another pipe system which is connected to the pipe 14. By operating a four-way cock 7, the heated water may be diverted to pass through the pipe system b in the direction reverse to that taken by the alcohol, a charge of sodium hydroxide or other cleansing substance being injected by a pump 10. A three-way cock 6, finally enables cold water to flow directly to the four-way cock 7, in either direction. To prevent water penetrating into the alcohol circuit, the four-way cock 7 is locked until the pump 2 is switched off. Indicator glasses 8, 9 are provided. A compact cylindrical apparatus is shown in Fig. 2 in which the tank 5 forms an annular chamber round the tank 3, the whole being surrounded with insulating packing and located eccentrically in the chamber 1. Above these parts the pump is mounted inside the condenser 4 which is formed annular. At the top of the apparatus the cocks 6, 7 are accommodated.

Filed: 1927-05-31
Abstract: 272,488. Soc. Anon. pour Tous Appareillages MÚcaniques. June 12, 1926, [Convention date]. Fixed-chamher apparatus comprises a pair of measuring-vessels, common feed and discharge conduits for said measuring-vessels, and a manually operated distributing device coupled with means for preventing the movement of the device during the filling or discharging of either vessel. Fig. 1 shows an apparatus comprising two measures a<1>, a<2> controlled by a valve b, which, as shown, fills the measure a<2> through a pipe c until the float-valve e<2> closes and the lever y, connecting the two float-valve spindles, rises, lifting a rod A and piston v. This lessens the compression of a spring w, and lessens also the pressure of a finger r on a bolt h and the pressure of the bolt h on the valve b, which may then be rotated to discharge the vessel a<2>. The liquid passes through the float chamber l and causes the float j to lift the bolt h, which prevents the rotation of the valve. Any attempt to rotate the valve b results in the bolt h entering a recess i<2>. When the measure a<2> is completely empty, the measure a' will have filled, and the pressure om the spring w will have relaxed; the bolt h will then be released by both the lever p<2> and the float j, and will release the valve b. 'The apparatus is applicable to devices with manuallyoperated and automatically-reversed valves b.
