Filed: 1939-04-05
Abstract: 531,818. Treating materials with gases. JORGENSEN, M. VOGEL-. April 5, 1939, No. 10659. [Class 51 (ii)] [Also in Group XXX] In a process for treating material with gas by drawing the gas transversely through a layer of the material on a gas permeable support, the support is inclined at an angle slightly less than the angle of repose of the material which is caused to slide as a whole down it, maintaining its initial uniform thickness, by reciprocating external action parallel to the support, the layer moving only on downward strokes. The process may be utilized to preheat cement raw materials or ores, or to cool cement clinker, or effect some chemical change such as the artificial ageing of cement by carbon dioxide. In Fig. 1, lime for a rotary kiln 1 is shown being conveyed down a grate 42 formed of inclined T-shaped bars alternately fixed and reciprocably supported on resilient bars 31, the lime being preheated by combustion gases from the kiln led through a firebrick lined chamber 5 to a sealed chamber 20 above the grate and drawn down through the material by a fan connected to an outlet 12 in a sealed chamber 21. A water-cooled rotary drum 15 forming a movable end wall at the bottom of a fixed curved extension 39 of the grate controls the feed of material which moves only if the drum rotates. Material falling through the grate is collected by hoppers 22, 23 and deposited on a feed conveyer 17. A partition 41 in the inlet hopper 14 permits a layer of some protective material for the grate to be used. The grate may be stepped transversely or lengthwise.

Abstract: 981,436. Compression-ignition engines. A. P. PEDRICK. April 20, 1964. No. 10790/62. Heading FIB. [Also in Division F2] The piston I of a compression ignition engine is pivoted on the crown thereof with a loose member 8 which, when the piston decelerates near top dead centre, moves away from the piston so that a spigot thereon enters a recess 13 and compresses mixture therein to a pressure above the spontaneous ignition temperature so that the ignition in the recess initiates combustion in the mixture in the remaining cylinder space. Alternatively, the spigot may be on the cylinder head and the recess in the member 8. The member 8 is secured to the piston in a loose but fluid tight manner by a bellows 11, the space 14 being filled with a coolant such as sodium into which project cooling ribs 12 of the member 8. Fuel-air mixture is drawn into the cylinder and the compression produced by the piston 1 in the main cylinder space is insufficient to produce spontaneous combustion. Holes in the member 8 assist the transfer of gases from one side thereof to the other. In a modification, Fig. 8, circular ribs 12 on the member 8 interleave with similar ribs projecting from the body of the piston and formed, for example, of copper.

IPC: H04N5/208
Filed: 1971-04-23
Abstract: 1291801 Television FERNSEH GmbH 23 April 1971 [29 April 1970] 11133/71 Heading H4F Contour enhancement of television signals is achieved by forming a difference signal (A 1 -A 0 ) from an undelayed signal A 0  and a signal A 1  which has been delayed by one line period (delay 10, Fig. 2), this difference signal (A 1 -A 0 ) being then delayed by a further line period (delay 13) to form a delayed signal (A 2 -A 1 ) which is subtracted from the difference signal (A 1 -A 0 ) to form a signal proportional to the contour enhancement signal {A 1 -¢ (A 0 +A 2 )} which in use is added to signal A 1  to form the improved signal for transmission. The advantage of this arrangement over the prior art (Fig. 1, not shown) is that only one low pass filter 12 (0-2 MHz) is necessary to ensure that all the components of the correction signal have the same band width. The mean value of the A 1 -A 0  (which is equal to zero) may be used to regulate the degree of amplification in the delay 10.

Abstract: 473,662. Carrier telephony. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. April 18, 1936, No. 11189. [Class 40 (iv)] [Also in Group XL] A common carrier source supplying a single frequency to intercommunicating subscribers is bridged across the line over which the communication takes place independently of the modulator-demodulators. These may be of the kind described in Specification 473,330, [Group XL]. Preferably the source is connected at the midpoint of the line or the shorter section is provided with additional impedance to make it electrically equal to the longer. Alternatively the two sections of the line may be separated as regards the carrier frequency and fed through different impedances. In one arrangement, Fig. 1 (not shown), the modulator-demodulator is a bridge, two adjacent arms of which are formed bv the centretapped primary of the line transformer, the telephone set being connected between the tapping point and the junction point of oppositely directed rectifiers forming the other arms. In modifications, Fig. 3, the secondary of a transformer VF for associating the telephone set is connected across one rectifier or, as shown in dotted lines, across both, a centre tap then being connected to the junction point of the rectifiers. Filters FC, FS keep the high and low frequency currents to their proper paths. Signalling impulses for ringing or selecting are transmitted by short-circuiting the line. The telephone set may have directional switching arrangements.

Abstract: The manufacture of filtering articles, which comprise granular inert material such as sand, granulated ceramic materials, clay or other siliceous or argillaceous materials, the granular material being provided with an oligodynamic metallic layer and bonded together by hydraulic cements, is characterized by using a hydraulic cement which does not release appreciable amounts of free alkali or cations of alkaline earth metals in the presence of water or by using with other hydraulic cements, one or more substances capable of neutralizing bases which may occur or be formed by hydrolysis during the use of the articles, in order to enhance the oligodynamic action of the metallic layer.  There may also be added to a part or to the whole of the granular material a neutralizing or slightly acidifying material selected from the group of absorbent siliceous or argillaceous associated with active silica, or containing absorbed thereon a reagent such as a phosphoric acid or an acid phosphate capable of insolubilizing the free or soluble bases of the hydraulic cement. The added material may alternatively be an ion-exchange resin capable of exchanging the cations of the soluble bases of the hydraulic cement for hydrogen ions.  The oligodynamic metallic layer is preferably silver, which may have associated with it up to 5 per cent by weight of metallic gold or rhodium as activators as described in Specification 699,172, [Group II].  The added neutralizing or acidifying materials are preferably in the proportion of 10 per cent or less of the hydraulic cement.

Abstract: 856,657. Transformers and inductors. VOGT & CO. April 11, 1958 [April 13, 1957], No. 11664/58. Class 38 (2). In a high-frequency coil having a tuning core, e.g. of sintered ferrite, adjustable by screwing, unwanted movement and play is prevented by a layer of polyvinyl chloride foam which contains a high-polymer softener, e.g. propylene adipate, to prevent adhesion and so facilitate re-positioning of the core. As shown, a threaded core 1 has a strip 2 of the foam filling its threads, but the foam may extend all round the core and/or may project beyond the threads (Fig. 3, not shown). Alternatively, a threadless core may be coated so that when screwed into a threaded bore a mating thread is formed in the layer, or the foam may be applied to the bore instead of the core. A foaming process is described which produces an elastic skin over the foam layer to provide a sliding surface, and where the layer is thin, i.e. at its boundaries 3 and 4, it consists wholly of the skin which assists in securing the layer to its bearer surface.
