Abstract: 1,132,932. Detecting neutrons. COMMISSARIAT A L'ENERGIE ATOMIQUE. 9 May, 1967 [25 May, 1966], No. 21558/67. Heading G6P. In a neutron counter using radiative capture, the (n, y) reaction provides radioactive isotopes emitting beta and gamma radiation. The reaction takes place within a Geiger-Muller type counter which detects the internally induced beta and gamma radiation. The counter has a halogen gas filling and comprises concentric electrodes, incorporating the rhodium isotope Rh 103, which after neutron activation produces Rh 104 and Rh 104 m. The first decays with a beta emission and a half-life of 44 seconds and the second has a gamma emission and a half-life of 264 seconds.

Filed: 1960-06-21
Abstract: 924,717. Protective arrangements. ALLMANNA SVENSKA ELEKTRISKA A.B. June 21, 1960 [June 22, 1959], No. 21670/60. Class 38 (5).

Title: Improvements in and relating to apparatus for diathermy and the like
IPC: A61N5/00
Filed: 1946-07-19
Abstract: 639,826. Power meters. GENERAL ELECTRIC CO., Ltd., and FURNEAUX, W. D. C. July 19, 1946, Nos. 21675/46 and 14439/47. [Class 37] [Also in Group XL (c)] In high-frequency heating apparatus, in which a power measuring device is connected at some point along the leads connecting the generator and the load, the leads are enclosed in electrostatic screening means and arranged so that their characteristic impedance is substantially constant in spite of movement of the leads or surrounding objects. The invention is particularly suitable for use with short-wave diathermy apparatus. The leads between the generator and the patient may consist of the inner conductors of two concentric cables, the outer conductors of which are connected together and earthed at the ends nearest the generator. Alternatively the two outer conductors may be connected together along their length except near the load, or the leads may be constituted by two conductors in a common outer shield. This shielding prevents radiation and absorption losses and if the internal losses are negligible the power fed to the load may be measured by a watt-meter connected at any suitable intermediate point in the leads. If the internal losses are not negligible the watt-meter may still be used to measure the power applied to the load, if the length of the leads is chosen such that the ratio of the effective loss resistance to the effective load resistance is constant in spite of changes in the load. This may be achieved by making the length equal to n#/2 - # where "#" equals the wavelength, " n " is an integer, and " # " lies between 0 and .05#. Alternatively, the power may be estimated by an experienced operator by the use of only a current or voltage meter connected at a distance n#/4 from the load and reference is made to Specification 468,398, [Group XL]. This arrangement however requires that the characteristic impedance of the leads shall be substantially constant and this condition is achieved by screening the leads as described above.

Title: Improvements in and relating to the Recording of Television Signals
Inventor: ROUT ERIC RAYMOND
IPC: H04N5/84
Filed: 1967-05-10
Abstract: 1,183,485. Recording television pictures. BRITISH BROADCASTING CORP. 10 April, 1968 [10 May, 1967], No. 21680/67. Heading H4F. The specification describes a method of recording television pictures on intermittently moving film wherein alternate fields 2, 4 &c. (see video signals in Fig.) are displayed on a first display screen A, the fields are delayed by a time T less than a field period and those delayed fields 1<SP>1</SP>, 3<SP>1</SP>, 5<SP>1</SP> &c. not displayed on display screen A are displayed on a second display screen B. The two display screens are photographed on the intermittently moving film, the movement of the film taking place during the interval T + t when no field is being displayed. Thus the film rate is 25 frames per second for a television frequency of 50 fields per second and the "pull down" time is extended. To take up no more than one film frame the two displays must be exactly aligned to form an interlaced picture, possibly by means of a prism module.

Filed: 1930-07-21
Abstract: 354,980. Boxes for gramophone needles. SCHARF, J. and SCHARF, H., (trading as SCHARF GEB.), 34, Skalitzerstrasse, Berlin. July 21, 1930, No. 21962. Convention date, Nov. 30, 1929. [Class 18.] A box for gramophone needles comprises tubular members 1, 9 slidable one within the other so that a single needle is fed into delivery position and removed from the container by means of upwardly projecting plates 6, 7, 8 carried by the member 1 acting in co-operation with a needle magazine 12 and inclined guide surface 14, 15 carried by the member 9. The tube 1 has a flange 2 so that by screws 4 it may be fixed to a gramophone 5. Vertical plates 6, 7, 8 are fixed to the bottom 3 of the tube 1 so that when the movable tube 9 is depressed the plate 6 will pass through the needle magazine 12 and a needle will roll down the inclined guide surface 14 so that when, under the influence of the spring 16, the tube 9 returns to the raised position, the needle 18 will come to rest on the top of the plate 7. By a repetition of these operations the needle passes by means of the inclined surface 15 to the plate 8 the top of which has a groove: to receive the needle and an aperture, across which the needle lies bridge-like to allow of its easy removal. The plate 8 projects from a slit 10 in the lid 11 of the tube 9 when this tube is in the depressed position. A pin on the tube 9 slides in a groove in the tube 1 to limit the movement of the tube 9 in either the upward or the downward direction. The lid 11 of the tube 9 is covered with a disc 23 rotatable about an axle 22 to an extent which is limited by an abutment 25 on the lid 11 moving in a slot 24 in the disd 23. By rotation of the disc 23 a slot 26 therein may be arranged to coincide with the slot 10 to permit of delivery of the needles. To refill the container the opening 27 in the disc 23 is made to coincide with an opening 28 in the lid 11 just above the needle magazine 12. If desired, instead of mounting the tube 1 on a gramophone it may be provided with a removable foot and used separately from the gramophone.

IPC: F02D9/00
Filed: 1949-08-26
Abstract: 690,280. Regulating; spray carburetters. BENDIX AVIATION CORPORATION. Aug. 26, 1949 [Sept. 18, 1948], No. 22275/49. Class 7 (iii) and 7 (vi). A fuel supply system comprises a conduit with a fuel metering restriction therein, means for varying the fuel pressure anterior to the restriction in response to variations in engine fuel requirements, a pressure creating means posterior to the restriction, and a fuel pressure regulating means communicating with the inlet and outlet of the pressure creating means for maintaining the pressure of the fuel in the conduit between the restriction and the pressure creating means at a value which is a function of atmospheric pressure or of an engine operating condition. As shown the fuel supply system comprises a metering device 10 from which the fuel flows through a pipe 90 to a pump 16 which delivers the fuel at increased pressure to a distributer 20 feeding fuel nozzles 22. Fuel from a pump 14 enters the metering device at 60, Fig. 2, and flows through a valve 64, controlled by the suction at the throat of a Venturi 34, and a passage 82 to a metering orifice 42 controlled by a valve 92 operated from the throttle valve 36. The pressure in the pipe 90 downstream of the orifice 42 is maintained constant by a by-pass valve 164, Fig. 3, carried by a diaphragm 176 subject to the pressure in the pipe 90 and by-passing fuel from the pump delivery pipe 152 back to the inlet pipe 90. The upper surface of diaphragm 176 is subject to atmospheric pressure through orifice 182; alternatively it may be subject to the suction at the Venturi 36 through a pipe 250, whereby the pressure in pipe 90 will vary in accordance with this suction. The pipe 152 leads to the distributer 20 comprising a fixed plate 192 with ports 198, a plate 196 angularly adjusted by a link 226 according to throttle valve position and having ports 216 corresponding with the ports 198, and a rotating plate 194 on a shaft 204 connected to the pump rotor 142 and having arcuate ports 205, 206, Fig. 9, to connect the ports 198, 216 together in succession to supply fuel through orifices 230 and pipes 232 to the nozzles 22. At full throttle the ports 198, 216 are in alignment for maximum fuel delivery, the plate 196 being adjusted to move the ports out of alignment, Fig. 9, as the throttle valve closes to reduce the period during which they are connected by the passages 205, 206 and thereby prevent large variations of pressure in the chamber 190. The plate 196 may be controlled by a device responsive to intake manifold vacuum. Specifications 577,770, 606,252 and 690,319 are referred to.

Title: Electroluminescent arrangements
IPC: H03K4/86
Filed: 1970-05-08
Abstract: 1313405 Electroluminescence ENERGY CONVERSION DEVICES Inc 8 May 1970 [16 May 1969] 22372/70 Heading C4S [Also in Divisions G5 H1 H3 and H4] A capacitive electroluminescent device is operated as a relaxation oscillator by connecting it to a resistor and to a bidirectional breakdown switch having a threshold recovery delay. The device may thus be operated from a D.C. supply. The switch used breaks down if the voltage applied thereto exceeds a given threshold value for a given time and when rendered non-conductive has a lower threshold value which recovers to the original value after a delay. In Fig. 1 the supply is normally below the threshold value of the device 14 so that the circuit has a stable "off" state in which light is not emitted. If the supply is raised above a threshold value for a time sufficient to render it conductive the capacitance of the electroluminescent device 14 discharges therethrough and the device thereafter becomes non-conducting. The breakdown threshold value is now of lower value and the cycle time is sufficiently short for the capacitance to recharge to the breakdown value before it drifts above the supply voltage and accordingly the cycle repeats and luminescence is sustained. If, however, the supply voltage is reduced or interrupted for the threshold recovery time the cycling ceases. Resistor 16 may be replaced by two to which half-amplitude start pulses may be applied respectively (Fig. 6, not shown). In Fig. 5 (not shown) the positions of the electroluminescent device and resistor are interchanged. A television or other graphic display may be formed from a co-ordinate array of the oscillators (Fig. 7, not shown). in which a single grounded transparent film electrode is provided on one side of the array and a co-ordinate grid of transparent conductors (e.g. of tin oxide) on the other, the substrate being of glass or clear plastic. The conductors are connected to sources (42, 44) which supply a steady D.C. voltage and start and stop signals. The other components may also be in deposited form.
