Abstract: 556,460. Moulding resin-impregnated fibrous material. KING, E. P. Jan. 26, 1942, No. 1095. [Class 87 (ii)] [Also in Groups XXIII and VIII] A panel member for use as a floor-board or bulkhead or for aircraft, marine craft or the like and for other purposes, of the kind comprising two sheets 12 of fibrous material such as plywood separated by stringers 13, also of fibrous material, all of which are impregnated and/or bonded with synthetic resins and consolidated under heat and pressure such as are normally obtainable in low-pressure plywood presses, is provided with laminated longitudinal and transverse stringers built up from light-weight timber or balsawood or formed material (produced, e.g. from polyvinyl acetate or chloride or artificial resin) bonded to impregnated veneer or paper.

Abstract: 1,243,283. Suction lifting devices. WELWYN ELECTRIC Ltd. 8 Jan., 1970 [8 Jan., 1969], No. 1221/69. Heading B8H. A suction lifting device for picking up small jobects 16, Fig. 1, comprises a wire 2 which is pushed downwards by members 24, 14 to hold the object in a recess 18 until a suction tube 1, to which suction is continuously applied through a conduit 5, is lowered into contact with the object. Diaphragm springs 7, 9, 15 support the members 1, 2 and the chamber 4 is sealed by diaphragms 8, 10. The bottom of the tube 1 may be provided with jewelled insulating inserts of different sizes.

Title: Improvements in or relating to radio apparatus
IPC: H03J7/22
Filed: 1959-01-14
Abstract: 849,394. Automatic tuning arrangements; transistor circuits. GENERAL MOTORS CORPORATION. Jan. 14, 1959 [Jan. 23, 1958], No. 1362/59. Classes 40(5) and 40(6). [Also in Group XXXV] In an automatically tuned transistor radio receiver the tuned circuits of the R.F., mixer and oscillator stages 34, 54, 76 respectively, comprise binocularly-wound ferrite cores 2, 4; 6, 8 and 10, 12 respectively. The ferrite cores are bridged across the soft iron pole pieces 14, 16 of a permanent magnet 18 the magnetization of which is progressively increased in steps to vary the inductance of the ferrite cores and so tune the receiver over its waverange. Magnetization is performed in steps by means of a winding 20 fed from a transistor 162, which is controlled by a multivibrator 150, 152; the pulses from the multivibrator are arranged to be of steadily increasing amplitude to step the receiver over the whole tuning range, by deriving its supply voltage from an emitter-follower 168, the base voltage of which comprises the voltage across condenser 158. Tuning is initiated by closing switch 164 which causes condenser 158 to commence charging over resistor 156. When the tuning range has been covered the magnetization may be removed and the system returned to its initial state by means of a demagnetization winding 22 which is energized by closing switch 242. The receiver includes an A.F.C. circuit comprising limiter 250 feeding a discriminator 264, 270 which is rendered inoperative for the duration of each stepping pulse by means of pulses derived from resistor 222 and applied to the emitter of the limiter 250 via line 256. In addition, pulses are applied from the multivibrator via resistor 210 to the base of a transistor 216 which provides a gate control circuit shorting out the discriminator output developed across resistor 272 during the stepping intervals. Between stepping pulses the limiter and discriminator are operative and if a signal is then received the discriminator produces an output which is applied via emitter-follower 284 to a D.C. amplifier 228 which provides an AFC control current in the magnetization winding 20. An output is also taken from the discriminator over resistor 296 to a transistor 300 providing a second gate control circuit which, if a signal is present, shorts out the multivibrator output and so terminates the stepping action. A station may be rejected and the stepping action restarted by momentarily opening and then reclosing switch 164.

Abstract: 120,156. Winters, A. M. Jan. 24, 1918. Fatty oils, extracting by solvents. Oil-bearing material such as offal or crushed seeds, beans, nuts, &c., passes from a hopper a, through one or more extracting-chambers b provided with conveying-worms c, wherein it is treated with solvents, such as benzine, supplied through the perforated shafts i of the worms or through perforations in the upper parts of the chambers covered by a jacket. As illustrated, solvent is supplied to the first two of the chambers but not to the third. The solvent passes from the chambers through removable sieves d and by pipes l into a chamber m containing inclined baffles o and sieves n and heated by steam from a pipe p. The solvent vapours are led to a condenser s, and the condensed solvent is returned to the extracting- chambers, water being separated in a gravity separator u. The oil is removed by pipe r. The material, after passing through the extracting- chambers, falls down a shoot v into a chamber w heated by steam from a pipe z and containing indined grids or sieves. The solvent is removed as vapour and is returned to the extracting-chambers by way of condenser s' and water-separator u<1>. Air, laden with solvent vapours from various parts of the apparatus, is passed through a washer 4 to separate the solvent.

Abstract: 108,301. Iki, O. July 24, 1916, [Convention date]. Recovering waste lubricants.-An apparatus for freeing boiler feed-water from oil comprises a tank having a wide shallow inlet 4' beneath which a floating board 8 is hinged at 7 so that its upper end distributes the incoming water in a shallow layer on the liquid in the tank to facilitate the separation of the oil. A floating box 9 extends obliquely from one side of the tank nearly to the other and is held by chains 10 and guided and prevented from turning by members 20, 21.

Title: Television receiver
IPC: H04N5/44
Filed: 1973-01-12
Abstract: 1406405 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 12 Jan 1973 [14 Jan 1972 (2)] 1843/73 Heading H4F A television receiver includes a storage tube 8 into which a single frame of a received television signal may be written by operation of a switch 3, operation of a switch 11 causing the stored frame to be repeatedly read-out from storage tube 8 and displayed on part of the receiver screen in place of the received signal, e.g. as shown at B, Fig. 3. To store a desired frame switch 3 is closed causing an output signal from circuit 4 to close switches 5 and 6 for one frame period, during which period the sync signals are fed to a sawtooth wave generator 7 and the video signals are fed to the storage tube 8. To view the stored frame switch 11 is closed manually, or automatically a predetermined time after closure of switch 3, which causes an output signal from circuit 12 to close switches 13, 14, 15, 16 and 17. The sync signals are thus fed to similar horizontal and vertical scanning signal generators 18, 25. Horizontal generator 18 includes an amplifier 23 which produces a square-wave signal at line frequency and this signal closes a switch 24 during one half of each line period to feed the output of a sawtooth wave generator 22, which produces a sawtooth signal of twice line frequency, to storage tube 8. A similar sawtooth wave of twice frame frequency is fed to storage tube 8 during half of each received frame from vertical generator 25. The line frequency square wave output of amplifier 23 also controls a change over switch 9 connected to receive the output of storage tube 8 and the received video signal. The similar frame-frequency square wave output from vertical generator 25 controls a further changeover switch 10 connected to receive the output of change-over switch 9 and the received video signal, so as to produce a display as shown in Fig. 3. Zooming of the displayed still frame B may be achieved by altering the scanning speed dictated by the sawtooth waves generated in horizontal and vertical scanning signal generators 18, 25, and the position of the still frame B on the picture tube may be varied by operation of variable delay lines included between switch 13 and generators 18, 25. Horizontal scanning generator 18, may be replaced by a circuit (45, Fig. 9, not shown) including a sawtooth generator providing a sawtooth signal at line frequency which is fed to a gate and also to a schmitt trigger which produces the square wave signal to control this gate and change-over switch 9. Vertical scanning generator 24 may be replaced by a similar circuit, zooming being accomplished by altering the threshold levels of the schmitt triggers.
