Title: A device for detecting leaks in pipes
Inventor: UPSTONE RONALD ALWYNE
IPC: G01M3/00
Filed: 1954-07-13
Abstract: 762,629. Detecting leaks in pipes. SCANTLEBURY, W. R. Dec. 2, 1954 [July 13, 1954], No. 20462/54. Class 99(2) A device for detecting leaks in a pipe comprises two inflatable containers which are adapted to be inserted into the pipe in spaced relationship and each of which is inflatable to a size such that obturation of the pipe can be effected substantially solely by the inflated container, means for inflating the containers so that they press against the walls of the pipe and seal off a testing space from the remainder .of the pipe, means for introducing a gas under pressure into the test space and means for detecting a change in the pressure in the test space. As shown, a test space 9 is sealed off by means of inflatable bags 1, 2 of rubber and canvas or like flexible and resilient material. A flexible tube 11 extends to an air compressor (not shown) whereby both bags may be inflated simultaneously. A flexible tube 17 leads to the air compressor and compressed air is supplied to the space 9 through the tube 4. The bags are connected together by means of a connecting rod or tube 8. A succession of joined rods 13 may be used to draw the bags 1, 2 through the pipe. An eye may be provided at the trailing end of the tube 5 so that the bags may be pulled back through the pipe if required. Alternatively the bags may be pushed through the pipe by a succession of joined rods. The flexible tube which supplies the test space is closed by a shut off valve and the test pressure is watched by an appropriately placed gauge. Known values are provided for the selective supply of the inflating and test pressures and the relief thereof. The tube 5 may be replaced by a rod or both the tubes 4, 5 may be solid the tube 17 leading through one of the bags.

Title: Apparatus system and method of storing a static image displayed on a tv tube
IPC: H04N7/173
Filed: 1974-05-09
Abstract: 1468039 Image recording EW SCRIPPS CO 9 May 1974 [11 May 1973] 20605/74 Heading G2X [Also in Division G4] An apparatus for storing an image formed by an image display device, such as a television tube, comprises a housing movable between a first position wherein the image surface can be viewed and a second position wherein the housing defines an enclosed chamber exposed to the image surface, a ferro-electric photo-conductor plate in the housing capable of recording an image when concurrently exposed to an electric field and the image and the plate being movable from a storage position in the housing in which the image formed by the display device is directly viewable to a position to receive and store the image. The plate may be of rhombohedral lead-lanthanium-zirconate titanate (PLZT) or other ferro-electric photo-conductor. The preferred storing plate includes a PLZT ceramic layer having a thin photo-conductive layer, e.g. of polyvinylcarbazole, applied to one surface and sandwiched between two transparent electrodes. The device is intended for recording static images such as those transmitted to a television receiver by the CATV system on request for information by a subscriber. As shown the apparatus for use with subscriber television receiver 20 includes a telescoping housing 60 surrounding the receiver and made up of sections 62, 64, 66, 68. Pivotable light sealing flaps operate when the housing is in the extended position, Fig. 8. When the receiver is in normal use screen 80 is exposed with the housing in its retracted position, Figs. 3 and 4. If an image is to be recorded the housing is moved to its extended position and auxiliary light source 90, image plate 100 and lens plate 130, supported by plates 132, take up the positions shown in Fig. 8, electrodes on the image plate engaging prongs 122 on socket 120, and sealing flaps 72, 74 exclude random light. Initially a uniform pre-polarization is applied to the plate by applying a voltage to its electrodes and exposing to uniform light from light source 90 or from uniform illumination provided by screen 80 of receiver 20. Then the light source is deactivated and the image is caused to appear on receiver 20 and is focused by lens 130 on to the plate 100 while applying a voltage to its electrodes and after sufficient time the image is recorded. The plate 100 is removed and viewed externally by a projection system and the image need not be retained on the receiver 20.

Speed measurement by sighting terrestrial objects.-In an instrument for use on aircraft for determining the ground speed, and of the kind in which a perforated or transparent strip is caused to travel, with reference to a sighting-aperture, at the same apparent speed as objects on the ground, the distance between the strip and the sighting aperture is adjustable. The slotted strip 7 is wound on spools 10 in a housing 13 and is uniformly moved by a sprocket 11 actuated by clockwork 12. The housing 13 is mounted on a casing 6 having the sighting-aperture 9 at its upper end, and can be racked vertically by the handwheel 14, the distance of the housing from the sighting-aperture being indicated on a scale 15.

Relates to C.W. telegraph receivers of the kind in which an audio signal is derived across the load resistor 4 of a detector 3 which is fed on the one hand from the incoming C.W. through the circuits 1, 2 and on the other hand by a local source connected at 9; and consists in applying such bias across the resistor 4 as will neutralize the bias produced by the detector when only the local oscillation is applied to it. In this way, the detector presents a low impedance to noise and interference, arriving through the coils 1, 2 during " space " periods and the overall signal-to-noise ratio is improved. The detector 3 may be a diode valve, and the neutralizing bias may be derived by connecting the resistor 4 in series with a variable high resistance 11 across the H.T. terminals 14, 8. When the switch 13 is opened, the circuit may be used for reception of C.W. telephony. Audio output is taken at terminals 7, 8 across the resistor 4.

At the studio the audio multiplex signals are demultiplexed at 6, the answer back signals decoded at 7 and fed to the control desk 8. Control signals from the control desk 8 are coded, by time division multiplex, at 9, and multiplexed with sound signals PTR and KTR in multiplexer 10 for transmission via the switch plane 11<SP>1</SP> of the cross-bar switch 11 back to the apparatus room 1 where the decoded control signals control the operation of the film and slide scanners &c., and the audio signals are used as required. The video signal channel from the studio B to the apparatus room 1 can be used for synchronizing signal transmission if not required for video signals. A carrier frequency modulator can be provided after the multiplexers 5 and 10 to shift the audio multiplex signals so that they may be fed through the same switch planes as the corresponding video signals V, or VR, and filtered therefrom after switching.
