As shown in Figs. 1 and 3, the film 2 is longer than the film 3 which is longer than the sheets 1, 4 which are the same length. The layers 1, 2, 3, 4 are aligned at one end adjacent to which they are heat sealed together along a line 10. At the opposite end, the strips 5, 6 are heat sealed along welds 7, 8, respectively, to the films 2, 3 and overlap the sheets 1, 4. The heat seal 9 delineating the shield seals the films 2, 3 to the strips 5, 6 at points 12. In use, a thermometer 11 is introduced into the space delineated by the seal 9. The strips 5, 6 and the top of the thermometer 11 are gripped by one hand and the other hand forms a grip outside of the seal 9, Fig. 1. The one hand is moved in the direction of the arrow and the shield is freed from the assembly of layers. In a modification, Fig. 4, the shield is a glove to receive a hand 11a. A plurality of shields may be provided in an elongate band, adjacent shields being attached by perforated lines (13), Fig. 2 (not shown).

Abstract: 970,004. Rotary-piston internal combustion engines. M. A. SHAHRESTANY. Sept. 9, 1963 [July 19, 1962], No. 27706/62. Heading F1F. A rotary piston I.C. engine of the intermittent abutment type, comprises a cylinder 1, Fig. 1, swept by a first two-armed piston 7, 8 keyed to a concentric main shaft 4 extending longitudinally of the cylinder and a second twoarmed piston 9, 10 mounted on a sleeve 11, Fig. 2, loosely surrounding the shaft and intermittently driven by the first piston through gearing 12, 13, 15, 16, Fig. 6. The gear 13 has half the number of teeth of the gear 12 so that the piston 9, 10 travels at twice the speed of the piston 7, 8 when teeth of the partly-toothed gear 15 engage the teeth of the gear 16. A spring- loaded pawl and ratchet device ensures unidirectional rotational of the second piston.

Title: An improved process and apparatus for the production of carbon by the dissociation of gases
IPC: C09C1/54
Filed: 1929-09-12
Abstract: <PICT:0340235/III/1> Soot is obtained by the splitting of gases such as acetylene in pressure vessels in which they are ignited and into which they are forced by a compressor consisting of high and low pressure and intermediate working cylinders, the hydrogen formed by the decomposition serving to tear off deposited carbon from the walls of the tubes on opening the release valve and being afterwards exhausted from a settling vessel into a storage tank.  The dissociation tubes a are provided at each end with stop valves, each comprising a conical part b<2> engaging a seating and provided on a member b<14> which is connected to the actuating spindle b<8> by a screw and slot allowing a certain amount of backlash.  A cushion b<15> is interposed between the member b<14> and a head b<18>, which is fixed to the spindle and carries a slotted deflecting cone b<16>. Within the casing of the inlet valve is a segmental rotary valve actuated through a lever b<10> and sleeve b<7>.  The gas to be treated is drawn into a low-pressure cylinder e<2> in which moves a piston secured on a rod e on which are also mounted the piston of a high-pressure cylinder e<3> and that of an intermediate actuating cylinder e<1> to which oil under pressure is admitted from a pipe f through an oscillating rotary valve f<1>.  Oil is admitted on either side of the central piston alternately through the engagement of the compressor pistons with levers l<1>, l<2> linked by mechanism not shown to the valve f<1>, the gas being thereby precompressed in the cylinder e<2>, and then further compressed in the cylinder e<3> whence it passes by way of an ignition chamber d<1> to the tube a. Oil from a reservoir h<1> is drawn into the compression cylinders behind the pistons on their compression strokes and serves for cooling the cylinders.  The ignition chamber is provided with a sparking plug c and a soot-removing scraper c<4> therefor.  An auxiliary plug c<6> may be brought into use if the plug c fails.  An inlet valve d<5> having a self-cleaning end d<4> admits gas to the ignition chamber.  After charging the chamber a and ignition of the gas, excess of pressure is reduced by allowing the hydrogen formed to blow off into a reservoir n.  The hydrogen still under pressure in the tube is then allowed to flow out through a pipe o<1> into a soot collector o<3>.  The valves b<2> are then both opened and hydrogen from the reservoir n is allowed to pass through the tube a, a whirling motion being imparted to the gas by the slotted cones b<16>, whereby soot is stripped from the interior of the tube and carried into the collector o<3>. After this proceeding the valve b<11> is opened and a current of hydrogen circulated through the tube a by the operation of an exhaust fan o<2>.  Soot deposited in the collector o<3> is removed through a slide valve o<10>.

Abstract: 1432254 Cathode-ray tube circuits BANG & OLUFSEN AS 12 June 1973 [15 June 1972] 27849/73 Heading H4T In an arrangement for automatically adjusting the cut-off point of the beam in a cathoderay display tube a measure of the cathode current is periodically produced and the bias potential between the cathode and a grid electrode is automatically adjusted to reduce the cathode current to substantially zero. As shown, during the scanning of the first or last few lines of each frame of a television picture, such lines being produced outside the visible screen area, a control circuit 30 responsive to an output from the vertical deflection generator 28 operates electronic switches 20 and 22 (only one shown) to replace the video (colour) input from video amplifier 18 to the control grids 12 by a constant voltage Vg and to interrupt the connection of the cathode(s) 10 to earth and to insert in those paths respective currant measuring devices 32 which produce an output voltage proportional to the cathode currents. The voltage produced by each device 32 is compared in a comparator 34 with the voltage Vg to produce respective output voltages which are employed via respective voltage dividers 16. to so adjust the voltages supplied to the screen electrodes associated with the respective electron guns such that the cathode current is reduced to a value close to zero (i.e. the cut-off point) the comparator or the voltage dividers including a time constant circuit which "holds" the adjusted voltages until the next frame occurs. In an alternative (and preferred) embodiment the voltages supplied to the screen electrodes are maintained constant and during the adjustment period, the cathode currents are employed to charge respective capacitors the voltages on which increase the cathode-voltages until the differences between the latter and the control grids becomes sufficient to suppress the cathodecurrent, the capacitor maintaining this condition until the next adjustment period. Instead of adjusting the cut-off points of all the guns simultaneously they may be adjusted sequentially and thus some of the circuitry may be common to all guns.
