Abstract: 1466265 Boxes &c. DRG PACKAGING Ltd 27 March 1974 [2 April 1973 3 Sept 1973] 15754/73 and 41393/73 Heading B8P A fold line 16 in an externally sheet lined box board component 10 comprises one or more slots 18 to prevent splitting of the lining on folding along the foldline to provide an externallylined bend. As shown, a tray, which has a slot 18 extending along a central creased foldline in the bottom panel 10 and cuts or cut-outs 22 in opposed side panels 14 is externally covered with a paper sheet 20, the edges of which are turned over the upper edge of the tray and adhered to the inner side panel surfaces. The slotted foldline facilitates folding up the tray without splitting the lining. The tray is held in the folded condition by a transparent plastics lid 24 permitting viewing of the contents. In a modification, Fig. 5 (not shown), two widely spaced parallel foldlines are provided in the tray to permit opposed end tray portions to be folded up and held erected by the lid. In the embodiment of Figs. 7 and 8 (not shown), two slotted foldlines define a central spine subdividing the tray into a base portion and a hinged fold-over lid portion. In a modification of this embodiment, Figs. 9 and 10 (not shown), a sleeve 58 is inserted into the base portion and frictionally engages the lid portion on folding over of the latter. The sleeve is retained in the base portion by a sleeve flap or tab 62, which engages over an inturned flap 50 on a side wall panel of the tray base portion. In a final embodiment, a cigar box comprises a folded-over tray slidable within an outer sleeve 72. The tray is similar to that of Fig. 9 but has cuts 74 in the tray bottom panel portions 32 and 34 in line with cuts through side wall panels 76 to define hinged lids 78. The tray is folded in half and adhesively secured by a strip extended around the periphery of the abutting edges of the folded-up tray halves. The folded-over tray is then slid into the sleeve 72, which retains the hinged lids closed until the tray is pushed upwardly.

IPC: F16K31/165
Filed: 1923-06-19
Abstract: 214,498. Pugnant, M. L. June 19, 1923. Valves controlled from a distance.-A valve device particularly applicable for use in high pressure gas lighting systems is opened by a sustained pressure variation and closed by one or more waves of reduced pressure. In the form shown, an actuating diaphragm 1 loaded by a spring 4 and subject to conduit pressure is coupled to a pawl 9 adapted to engage teeth on the edge of a multi-ported rotary disc valve 10 or on a disc secured to a plug cock. Some of these teeth 11<a> are of large pitch and are separated by one or more teeth 12a, 12b of smaller. The Figure shows the apparatus in the inoperative position. When the right pressure is put on the diaphrogm is pushed back and the pawl engaging the large tooth rotates the valve to the open position. To close the valve the pressure is reduced to an intermediate valve causing the pawl to engage the first small tooth 12a so that when the pressure is restored the valve is closed. A second wave restores the device to its original position. Any number of small pitch teeth may be employed.

Abstract: 1,022,286. Cooling discharge apparatus. COMPAGNIE FRANCAISE THOMSONHOUSTON. April 24, 1963 [April 27, 1962], No. 16213/63. Heading H1D. In an evaporative cooling system comprising a heat-dissipating structure 1 having one surface 8 exposed to a source of heat and an opposite surface exposed to a vaporizable fluid 17 and provided with heat-dissipating formations 6a, 6b, the heat-output surface has both its ends C, D displaced or offset with respect to the corresponding ends A, B of the heat-input surface in a direction generally parallel to both surfaces to such an extent that the major part of the heat output surface lies beyond the heatinput surface, so that a steady temperature gradient exists in this direction over the heat-output surface. This temperature gradient prevents spheroidal-state ebullition of the vaporizable fluid, e.g. water, and accompanying hot spot formation. As shown, the heat-input surface 8 comprises the anode surface of a high-power tetrode and is formed with radial slots 7a, 7b to take up differential expansion. The lower end of the heat-output surface terminates in a radiallyextending flange, having an outer part 14 of an alloy having a low heat conductivity relative to copper structure 1, and providing a seating for boiler 16.

Title: Improvements in or relating to thermionic amplifiers

Filed: 1934-05-31
Abstract: 417,440. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. May 31, 1934, No. 16280. Convention date, June 20, 1933. Addition to 388,292. [Classes 39 (i) and 40 (v).] An amplifier of the kind described in the parent Specification, in which grid bias is automatically adjusted according to signal volume with the object of saving plate current, is modified by arranging the rectifier in one of the amplifying valves, preferably a valve in an earlier stage of the amplifier. As shown, part of the output across a choke coil 9 or transformer in the final stage 1 of the amplifier, is fed through condensers 26, 27 and resistance 28 to a rectifier formed by an anode 25 and a cathode 23 heated by the filament of an earlier valve 2. The resulting D.C. voltage across the resistance 28 is smoothed by condensers 31, 32 and is applied to the grid of the valve 1 in opposition to the voltage of a battery 33 thus giving high negative bias when the signals are weak and less bias as the signals increase. The cathode 23 may be heated by a separate filament connected in parallel with the main filament of the valve 2 ; or the main filament may form a directly-heated cathode for the rectifier. A resistance 29 is connected across the rectifying circuit. In a modification, a push-pull pair of valves is employed in the output stage. An inductance coil may be connected in series in the rectifier circuit to diminish the frequency-discriminating effect of the series condensers 26, 27.
