Abstract: 583,289. Wrappers. AMERICAN VISCOSE CORPORATION. Oct. 16, 1944, No. 19921. Convention date, Oct. 16, 1943. [Classes 94 (i) and 94 (ii)] A wrapper of paper, or like material, is provided with numerous slits 3, in rows, to facilitate wrapping around an article such as an annular cake C. Parts of the wrapper may remain unslitted. The slits may be arranged in various ways but at least one row has slits staggered relative to one or more other rows. In Fig. 5, an un-slitted portion 8 of the wrapper is placed inside an annular cake C, the part 10 of the wrapper being placed over the top and afterwards covered by the part 11. The apparatus described in Specification 565,705 may be used for wrapping. In Fig. 8, the cake C and wrapper rest on a plate 15 which may pass to the bottom of a cup 18, the sides of which force the part W of the wrapper upwards. The skirt of W is then tucked into the top of the cake. Fingers 16 are moved radially to position the wrapper inside the cake.

Title: Improvements in or relating to electric pulse code modulation systems
Inventor: TREADWELL CYRIL GORDON
IPC: H04B14/04
Filed: 1954-07-12
Abstract: 750,579. Pulse modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. July 12, 1954, No. 20297/54. Class 40 (5). Relates to an arrangement for producing signal wave amplitude samples all of the same polarity but occurring on one conductor if the wave ordinate is negative when sampled and on a second conductor if it is positive, for application to a pulse coder. As described, the input wave is applied to a transformer 105, the centre tap of whose secondary is connected to earth through a resistor 110, across which a gating pulse is developed. The ends of the secondary are connected through similarly-directed rectifiers 114, 115 and conductors 89, 90 to the grids of cathode followers 127, 128, respectively, which have a common load resistor 134, fed through isolating rectifiers 132, 133. The signal sample is developed across resistor 134 and is fed to the coder over conductor 98. Conductor 97 from the coder is connected to the cathode of valve 128, to deliver a signal only when a sample appears on conductor 90, in order that the first code digit pulse may be suppressed when the corresponding signal wave amplitude is negative. The positive channel gating pulse from the amplifier 106, across resistor 110, is accurately limited to an amplitude E1 by connecting the live end of 110 to the conductor 86 at the potential E1 of a bias source 85, through a capacitor 112 and rectifier 111. While is exists, the potentials at the ends of the secondary of transformer 105 are therefore E1 the sample signal voltage, respectively. The cathodes of rectifiers 114, 115 are biased to + E1, from the conductor 86, through inductors 123, 124 respectively, so that when the gating pulse occurs the sample signal voltage is communicated to conductor 89 or 90 depending upon its polarity. It is limited to a value + E2 by connecting this voltage from conductor 87 of source 85 to the junction of opposed rectifiers 116, 117, connected across the secondary of transformer 105, together with the voltage E1 produced across inductor 118 by the gating pulse from resistor 111 through capacitors 119, 120. Specifications 587,939, [Group XL], and 750,577 are referred to.

Abstract: 944,856. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 14, 1962 [June 6, 1961], No. 20385/61. Heading H3T. A switching arrangement for delivering an output whose polarity depends either upon the polarity or upon the presence or absence of input signals comprises an alternating-current source, such as inverter circuit IC, and two circuits 10, 10 and 11, 11 coupled thereto and such that one conducts during one set of alternate half cycles of the alternating-current source to apply half-wave rectified current pulses to terminals 14, 15 of a switching network SN1 comprising four transistors whose emitter-collector paths are connected to form a bridge and the other conducts during the alternate set of alternate half cycles to apply half-wave rectified current pulses to terminals 18, 19 of a second switching network SN2 similar to network SN1, terminals 12, 13 of network SN1 and terminals 16, 17 of network SN2 being connected as shown to output terminals 5, 6 and the input signal being applied to a diode switching network PR to control the polarity with which the alternating current generated by inverter IC is applied to the primary winding T3(P) of a transformer T3 having four secondary windings coupled between the base electrodes of the transistors of the switching networks SN1, SN2 in such a fashion that for an input of one value one pair of transistors of each of switching networks SN1, SN2 is rendered conductive when the corresponding circuit 10, 10 or 11, 11 is energized to result in terminal 5 being sent positive with respect to terminal 6 and for an input of the other value the other pair of transistors of each of the switching networks SN1, SN2 is rendered conducting when its corresponding circuit 10, 10 or 11, 11 is energized to result in terminal 5 being sent negative with respect to terminal 6. Double-current telegraph signals having a maximum repetition rate low compared to the frequency of inverter IC applied at input terminals 7 are repeated with a reversal of polarity at output terminals 8. Thus if terminal 3 is positive with respect to terminal 4 diodes MR1, MR2 of network PR conduct so energizing transformer T3 that during the half cycles when transistor TR9 conducts and current flows anticlockwise in the circuit 10, 10 transistors TR1, TR4 conduct and a negative potential appears as terminal 5. During each following half cycle when current flows anticlockwise in circuit 11, 11, transistors TR5 and TR8 conduct and negative potential continues to appear at terminal 5. With a reversal of polarity at terminals 3, 4, transistors TR2, TR3 conduct alternately with transistors TR6, TR7 so that a positive potential appears at terminal 5.

Abstract: 1313882 Cine cameras EASTMAN KODAK CO 28 April 1970 [28 April 1969] 20424/70 Heading G2E A cine camera with provision for making single exposures has a socket 20 for a multiple flash-lamp unit 22, and means for synchronizing energization of the lamp with shutter 42 comprising a cam 116 on the rim of the shutter which closes contacts 112, 114 in the lamp circuit. Depression of shutter release 16 lowers member 74 until portion 76 shifts frame 66 and so disengages slot 70 from a lug 64 extending from drive-shaft 48. Continuous running then commences unless control knob 18 has been withdrawn whereby portion 76 also shifts frame 68 to raise a latch 92 which engages lug 64 after one rotation. In the withdrawn position of knob 18, a spring-latch 142 on member 74 may engage and pull down a retaining member 128 until surface 150 of the latch is tripped by a pin 150 to release member 128 which then returns upwards under spring 138, and in so doing permits a quarter revolution of a plate 118 carrying lamp socket 20. Lugs 126 on plate 118 successively engage members 130, 135 of member 128, under pressure from a manually tensioned torsion spring 124, on each return stroke of member 128.
