Title: Method and apparatus for measuring residual stresses in structural members
Inventor: VINOKUROV VITALY ALEXANDROVICH
IPC: G01B7/16
Filed: 1966-04-20
Abstract: 1,149,636. Measuring strain electrically. V.A, VINOKUROV. S.N. KISELEV and V.A. KHAVANOV. April 20, 1966, No. 17293/66. Heading G1N. The residual stresses in structural members that have been subjected to, e.g. welding or machining, are measured by drilling a hole in the structure and cementing into this hole a plug of e. g. epoxy resin, containing three or four strain gauges. A cylindrical core coaxial with the hole and of at least five times the diameter of the hole is then removed from the structure. Any distortion of the core due to being relieved of its internal stresses is measured by the strain gauges which may be disposed in the resin plug in various configurations Figs. 2 to 4 (not shown).

Title: Improvements in or relating to cathode ray tubes
IPC: H01J31/20
Filed: 1953-06-23
Abstract: 731,124. Cathode-ray tubes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 23, 1953 [July 30, 1952], No. 17344/53. Class 39 (1). A cathode-ray tube comprises a gun for producing a single beam and a separating electrode structure 26, Fig. 3, for splitting the beam into three independently controllable beams comprising three plates 28 joined at a common edge to form a Y-shaped structure the three arms of which are equally spaced, the plates extend parallel to the gun axis, and their common junction point lies along the gun axis. The beam passes successively through ratio section 22, Fig. 2, beam splitting section 26, Fig. 3, and positioning section 30, Fig. 4. In the ratio section it is deflected towards whichever of independently-energized plates 23, 24, 25 is momentarily more positive, and is consequently split unequally by splitting electrodes 28, the latter tending to deflect the beams outwardly. In the positioning section 30 plates 32 are positive with respect to plates 34 to provide independent radial deflection adjustments for the three beams. The beams can be independently intensity-modulated. Electrodes 28, 34 can be integral. A focusing coil (not shown) renders the three beams parallel to the tube axis. The fluorescent screen may produce a single colour or preferably plural colours as in a colour television receiver.

IPC: H02P23/00
Filed: 1963-05-02
Abstract: 1,038,046. Automatic control of prime movers. ELECTRONIC ASSOCIATES Ltd., and D.J.STRONG. May 1, 1964 [May 2, 1963], No. 17439/63. Heading G3R. A reversible motor 21 actuates fuel rack or valve 22 of engine 10, a position monitor being linked with the member 22, and the speed of the engine being monitored by tachometer generator 11. An amplifier 19 receives the speed and position signals and supplies an output signal to motor 21. The amplifier 19 has a feed-back loop 20 which is substantially resistive, a further amplifier 15 having a feed-back loop 16 which may be switchable to be either resistive or resistivecapacitive. The amplifier 15 receives the speed signal and has its output attenuated by potentiometer 18. When the engine 10 drives a generator in parallel with another, a speed-trim control member 17 is associated with amplifier 15 for determining the proportion of the load supplied by each generator. The percentage decrease in engine speed on application of a given load is regulated by adjustment of potentiometer 18. The tachometer generator 11 is associated with transformer 12 and speed-sensing circuit .13 which is frequencysensitive. The voltage from the transformer 12 is clipped and filtered and then applied to transformer 35. Capacitor 39 and resistor 41 are so chosen that, when the frequency of the speedresponsive signal deviates from a fundamental value, the voltage across resistor 43 remains the same whilst that across resistor 42 varies. The smoothed opposed-voltages appearing across resistors 50, 51 become unequal so that a D.C. error signal is developed across terminals 45, 52, for application to the amplifier 15. A signal representing the rate of change of power developed by an engine-driven generator may also be fed to the amplifier 15. In another arrangement, a pair of dieselgenerator sets supply a common load at constant frequency, each set contributing a selected proportion of the total power. Each set has a wattmeter for monitoring power output, as well as a speedsensing circuit. The output signal from one powermonitoring device is differentiated for speed control. The load is apportioned by comparing signals from each power-monitoring device,the error signal being used to control the speed of one of the sets, Fig.3 (not shown). In a further embodiment, the power plant of a diesel-electric locomotive comprises an engine driving a main generator and a pilot generator providing field excitation. A D.C. tachometer generator affords a speed-control signal to a governor for regulating a fuel rack. A wattmeter provides a further signal to a governor for the field regulator. Progressive manual adjustment if a master controller increases the power output of the main generator continuously, the engine-speed being increased step-wise, Fig.4 (not shown).

Abstract: 403,711. Drying sheets. SOWDEN, F. H., 12, Wellhouse Avenue, Harehills, Leeds. June 22, 1932, No. 17601. [Class 34 (ii).] In delivery apparatus for printing and other machines, the sheets 1 received from tapes 2 are disposed radially around central gripping means while being carried through a circular path before the final delivery so as to dry the sheets. The platforms consist of bars 9, Fig. 1, attached radially to a shaft 7, with or without thin metal sheets extending between adjacent pairs of bars 9. Grippers are provided at the inner end of each pocket formed by adjacent radial sets of bars and comprise a series of teeth 14, Fig. 3, on a disc 12 on the shaft 7 with which co-operate spring-pressed jaws 19 pivoted on the disc. An adjustable cam 22 engages inwardly-projecting parts 20 on the jaws 19 so as to cause them to open for delivering a dried sheet and to receive a sheet from the tapes 2, and to close and grip a sheet in the pocket as the platforms move around the shaft 7. A step-by-step rotary movement is imparted to the shaft 7 by pawl-and-ratchet mechanism 52-56 operated from an oscillating shaft 48. The sheets are released adjacent to a reciprocating delivery-carriage 57 operated from the shaft 48 and having grippers 60, 63, which engage the outer edge of the sheet. Curved guides 39 prevent the sheets leaving the pockets until engaged by the grippers. A pusher member 73 pivoted on the cam 22 is operated from the ratchet-levers 54, 55 so as to move each sheet positively into the grippers 60, 63 which have stops 64 limiting such movements. Tapes 67 attached at one end to a weight 69, unwind from a roller 68 on the carriage 57 as it moves away from the platforms so as to support the sheet which is released from the grippers at the end of the outward travel. As the carriage moves in the reverse direction, the roller 68 is caused, by a wire passing around the roller 68 and secured at its free end to the framework, to wind up the tapes 67 and thus drop the sheet on a delivery pile.

Abstract: 1310159 Heat-treating films E I DU PONT DE NEMOURS & CO 14 April 1970 [14 April 1969] 17743/70 Heading B5B A process for preparing dimensionally stabilized substantially flat plastic film comprises passing a plastic film which has a residual shrinkage between, but out of contact with, a heat source and a heat-sink which is cooler than the heat source. The side of the film nearer the heat-sink is supported on a layer of gas and the film is urged towards the heat sink, against the pressure of the gas. The gas pressure, film speed, tension, the temperatures of the heat source and the heat sink, and the distances between the heat source, heat sink and the film are varied to produce a self-regulating flattening of wrinkles and dimensional stability. Under those conditions, those parts of the film which shrink more easily than the rest move towards the cooler sink because of the tension urging the film in that direction. Those parts of the film which are more reluctant to shrink remain nearer the heat source and receive the necessary greater heat-treatment. This gives a more uniform shrinkage and absence of wrinkles. In the apparatus of Fig. 1, the film 10 is fed around tension roll 12 towards tension roll 15. Between these rolls there is heat source 13 and heat sink 14 both having the form of an arc. The tension urges the film towards sink 14 against the pressure of a gas which issues through the surface of the sink 14. The film may be slightly stretched between nip-rolls, as in the embodiment illustrated in Fig. 3 (not shown). In the examples a polyester, in particular polyethylene terephthalate, films are treated and show a shrinkage as low as 0À1% at 105‹ C.

Abstract: 863,998. Heating semiconductors by electric resistors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 21, 1959 [June 5, 1958], No. 18013/58. Class 39(3). [Also in Group XXXVI] An NPNP structure as shown in Fig. 3, for example, is produced by melting the tip of a monocrystalline semiconductor body containing both donor and acceptor impurities, the impurity with the lower segregation coefficient being dominant and recrystallising to form an NPN (or PNP) structure and then fusing a pellet of impurity to the end of the recrystallised region to form the last zone of opposite conductivity type. Fig. 4 shows a suitable apparatus for the melting and remelting processes. A chuck 14 holds a body of N-type germanium containing antimony and gallium, the tip of which is melted by nickel-chromium electric heating element 16 fed via conductors 17, in an atmosphere of hydrogen supplied from pipe 19. An automatic timing circuit controls the durations and power of separate heating cycles to the element whereby the tip is melted, then recrystallised slowly to form a relatively thick P-layer, then cooled rapidly to provide the remaining N-type region. The heating element is then energised to re-melt the N-type region and part of the P-layer and then switched off to allow all the last melted region to crystallise out as N-type material. This allows the final width of the P-region to be more closely controlled. A blob of indium is attached to the N-type region, and the tip again melted and recrystallised slowly and then rapidly, to form the final P region. Ohmic contacts to the end regions are provided. The forward characteristic of the device has first a high impedance region until a striking voltage is reached, and then a low impedance region; the element may be used in a bistable switching circuit. Specifications 752,457 and 781,795 are referred to.
