IPC: B29C67/00
Filed: 1946-06-25
Abstract: 613,665. High-tension switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 25, 1946, No. 18953. Convention date, July 31, 1945. [Class 38 (v)] In a high-voltage circuit-breaker with two or more series breaks, the even voltage distribution across the gaps is maintained under normal conditions by parallel-connected voltageindependent resistances and under over-voltage conditions by parallel-connected voltage-dependent resistances which have an inverse resistance/voltage ratio and also help to limit the restriking voltage. Each series break may have resistances of both kinds connected in parallel with it or alternatively an ohmic resistance may be connected in parallel with each break, together with a voltage-dependent resistance in parallel with the row of gaps. One of the types of resistance may be in the form of a hollow cylinder into which the other type of resistance may be inserted.

Abstract: 1,245,570. Dishwashing machines. TRIPLEX S.p.A. April 21, 1970 [Feb. 14, 1970], No. 18991/70. Heading A4F. A dishwashing machine has a device for aspirating, at the end of a drying phase, steam from one or more openings formed in the top part of the crockery container and at the same time cooling at least one wall of the container to condense residual steam. Water passed through a tube 4 having a restricted outlet 7<SP>1</SP> aspirates steam from the crockery container A through a tubular fitting 3 and a chamber 8, and flows through an elbow 10 into the container A to be diverted by a baffle 14 to flow against and thereby cool the wall 1 of the container. A further baffle 12 causes the aspirated steam to pass from the container A to the fitting 3 via a narrow opening 13 adjacent the cooled wall 1. The water passed through the aspirator may be collected in the container A and recirculated through the aspirator by a pump.

Title: Improvements in or relating to means for locking valves or closures in fluid tight position
IPC: B64D25/00
Filed: 1947-07-17
Abstract: 627,168. Inflating devices. FISHER, F. R. July 17, 1947, No. 19091. [Class 77] A device for locking valves or closures in an air-tight position, applicable particularly to valves for inflatable life-belts, comprises a screwed sleeve having a seating for a washer against which a flange of an arm-carrying member is pressed to form a fluid-tight seal by a cap screwed on to the sleeve, means for securing the screwed sleeve to a flexible body or container, cam means on the arm-carrying member for opening a valve or closure of a charging device and means for positively locking the cap to the arm-carrying member in a predetermined position for operation. The screw-threaded sleeve 7 passes into an aperture in the flexible body 9 and is secured inside the body 9 by a screw-threaded ring 8. The arm-carrying member 3 fits within the screw-threaded sleeve 7 and carries a flange 4 which bears against a washer 5 positioned in a recess of the sleeve 7 to form an air-tight seal when the cap 15 is screwed into position outside the flexible body 9. The cap 15 is held in position by a pin 32 passing through holes in both the arm-carrying member 3 and the cap 15. The end of the arm-carrying member 3 within the flexible body is in the form of a cam 17 fitted by a fulcrum pin 19 between the forked ends of a sleeve 21 into the other end of which a sealed charging cylinder 23 is screwed. A plunger 22 is disposed within the sleeve 21 and may be moved against a spring 26 to pierce the seal of the charging cylinder 23 by rotation of the cam-shaped end 17 of the arm-carrying member 3 about the fulcrum pin 19. Gas then escapes into the flexible body by way of a groove 28 in the plunger 22 and a groove 28<SP>1</SP> in the sleeve 21. The arm-carrying member 3 is provided with a pivoted or rigid handle 1 and is locked in operative position by a projection 14 on the flange 4 which fits within a recess in the screwthreaded sleeve 7. Inadvertent unscrewing of the charging cylinder 23 is prevented by a twodimensioned coiled spring. When the invention is to be used for the inflation of a lifebelt it is positioned in an aperture in the lower edge of the lifebelt so that the handle 1 may be easily knocked upwards in order that the seat of the charging cylinder 23 may be pierced.

Title: Improvements relating to the production of stereoscopic images
Inventor: KRAMSKOY CHARLES MARK
Filed: 1950-08-02
Abstract: 700,982. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 2, 1951 '[Aug. 2, 1950], No. 19257/50. Class 40 (3) Apparatus for producing stereoscopic images comprises a television pick-up tube 1 mounted on a mobile craft, such as an aeroplane and controlled so as to generate picture signals in successive frames, a pair of cathode-ray tubes 23, 24 and gated means 21, 22 for feeding the picture signals to the tubes in such manner that picture signals generated during a first sequence of frames are fed exclusively to one tube and picture signals generated during a second sequence of frames intermediate the first sequence are fed exclusively to the other tube. The arrangement is such that the images reproduced by the tubes produce a stereoscopic effect by virtue of the movement of the pick-up tube between frames. The gates may be switched at frame rate so as to exhibit alternate frames. Alternatively the switching may be effected at a sub-multiple of the frame rate so as to increase the stereoscopic base, one gate being opened, for example, during fields 1, 5, 9 &c. and the other gate being opened during fields 3, 7, 11 &c. The cathode-ray tubes may be photographed, or the images may be projected on to a single screen for direct observation, polarized light filters and spectacles being employed to distinguish the images. As illustrated the cathode-ray tubes are located remotely of the mobile craft and the signals are communicated over a radio link which may include intermediate stations. In an alternative arrangement, Fig. 1 (not shown), the cathode-ray tubes are carried on the mobile craft. In the arrangement illustrated, the switching between the two cathode-ray tubes is controlled from the transmitter on the mobile craft so as to prevent the images becoming transposed by a synchronizing signal generator 14 producing frame synchronizing signals as shown in Fig. 4 in which the number of pulses 17 and 18 differ in alternate frames. At the receiver, the synchronizing signals control the scanning in the normal manner and are also applied to a discriminator 25 which consists of a trigger circuit having one stable and one unstable state. The recovery time of the circuit when changed to the unstable state is arranged to exceed the duration of the shorter frame signal but to be less than the longer frame signal. Thus on the occurrence of odd-numbered frames single output pulses 26, Fig. 5, are produced and on the occurrence of even-numbered frames double pulses 27, 28. These pulses are then applied to an electronic relay 29 controlling gates 21, 22 so as to effect the switching of signals between the cathode-ray tubes. The stereoscopic base may be increased by employing a dividing circuit to reduce the switching rate. Cathode-ray storage tubes may be included between the gates and the cathode-ray tubes to enable images to be presented continuously.
