Title: Improvements in and relating to the generation of pulse-modulated oscillations
IPC: H03K7/00
Filed: 1947-07-25
Abstract: 652,872. High-frequency electric filters. GENERAL ELECTRIC CO., Ltd., and LEVY, M. M. July 25, 1947, No. 20101. [Class 40 (viii)] [Also in Group XL (c)] Following modulation of a carrier, side-band components are selected extending from the carrier over a desired band, components outside this band being excluded. The selecting means may also exclude or substantially exclude parts of the desired band on either side of and adjacent the carrier frequency. The selecting means may be a band-pass filter which should have a constant input resistance over the frequency band employed to prevent reflection of the unwanted energy back into the carrier generator. The filter may be composed of one band-pass filter feeding the aerial and one bandstop filter terminated in a dummy load. The impedance of the two filters in parallel is constant if the terminating half-sections are m-derived and are so designed that m=0.6, and for the same load resistance and if the usual shunting impedances at the inputs of both filters are omitted. In an arrangement for transmitting a pulse-modulated carrier, a magnetron radio-frequency pulse generator 15 is connected to a hybrid wave-guide junction 16. Energy enters at Y and appears in phase at V and X, no energy passing directly from Y to Z. The energy at V passes to a band-stop filter 17 terminated in a dummy load 18 while the energy at X passes to a second band-stop filter 19 terminated in a dummy load 20. The connection from V to 17 is longer by #/4 than the connection from X to 19 so that energy in the desired band reaches V after reflection at 17 with a phase displacement of its voltage of #/2 relative to that reaching X after reflection from 19. These energies combine with their voltages in phase and pass to the aerial 21.

Title: Improvements in or relating to the separation of dust from air and gases
IPC: B01D47/06
Filed: 1929-07-04
Abstract: 336,221. Raw, G. July 4, 1929. Gases, washing.-Dust is separated from air or gas slowly rising from a body of material, e.g. coal, under pneumatic drying treatment, by producing a mist of finely-atomized liquid and causing the dust to coalesce and sink by gravity, the mist being of fine particles not sinking by themselves and admitted in such small quantity that the moisture in the settled dust is practically imperceptible. Gas is blown through pervious decks a<1> through coal a or the like and rises into a large chamber c in which the gas becomes almost stagnant and is treated with atomized water sprays g' from pipes g. Dust is precipitated on to the lower steeply-sloping sides d<1> into vertical shoots d, e, while gas escapes at h. Each spray g' may comprise a nipple j with a cylindrical nozzle-member k with a domed interior l and a central outwardlyflared discharge orifice m. A narrow passage p in the member k passes water tangentially into a whirling chamber l' formed by closing the dome by a screwed plug n. Alternatively, air is blown from nipples q in a pipe r over narrow adjustable tubes t dipping into water conduits s. The water level in the conduits is automatically maintained constant, and the nozzles and tubes are adjustable. The tubes may be bent to deliver water from above. Wetting or penetrating agents may be added to the liquid. Specifications 274,587, [Class 117. Sifting &c.], and 314,110 are referred to.

Abstract: 685,431. Combined range- and view-finders. KODAK, Ltd. Sept. 3, 1951 [Sept. 1, 1950], No. 20772/51. Classes 97 (i) and 98 (i). A combined range and view-finder comprises a view-finder objective for forming a real image of an object, which image is erected by means including four plane reflecting surfaces, two of which are crossed, a pair of range-finder reflectors disposed one on each side of the erector means for reflecting range-finding beams into the crossed reflectors whereby these beams are directed in juxtaposition along paths parallel to the axis of the view-finder objective, and an eye-piece for receiving and transmitting the range-finder beams and the view-finder beam. In one form, the apparatus includes a view-finder objective 11 forming a real image of the object at a field lens 12 and a prism system 17, 18, 19, 20 for erecting this image and directing the light into an eyepiece 15 through which the image may be observed. Range-finding mirrors 32, 33 of which mirror 33 is rotatable and may be coupled to the objective focusing mechanism of a camera by a lever 40 and cam 42, direct beams 30, 31 from the object on to the crossed reflecting surfaces of prisms 17, 20 whereby these beams are directed through a part 27 of the eyepiece. This part is of zero focusing power and is wedged to deviate the rangefinding beams towards the axis of the eyepiece. The beam 30 passes through a part 26 of the prism systems, this part being disposed normally to the beam. In a modification, the field lens 12 is omitted and the objective 11 forms an image of the object in the exit face of the erecting prism. The range-finder includes pentagonal prisms, the light to one of which passes through a pair of relatively adjustable wedges, and in the light path from each pentagonal prism to the erecting prism is an objective whereby two range-finding images are formed in the exit face of the erecting prism. If it is desired to form the range-finding images in a different plane from the view-finding image, the eyepiece must be bi-focal and in this case may comprise two parts, one of which is wedge. shaped. The erecting prism may be replaced by four plane mirrors.

Title: Production of electrical energy by the electro-chemical reaction of hydrogen and oxygen gases with catalysts in the presence of an electrolyte
IPC: H01M8/08
Filed: 1963-05-27
Abstract: 999,511. Fuel cells. ALLIS-CHALMERS MANUFACTURING CO. May 27, 1963 [May 31, 1962], No. 21065/63. Heading H1B. A fuel cell utilizes an integrated gaseous mixture of hydrogen and oxygen, produced by the decomposition of water. The gas mixture enters the oxidant space 35 through an inlet 37 and engages a cobalt oxide catalyst on the cathode 31 which selectively removes, by absorption, oxygen from the mixture. The gas leaving the exit 38 is mostly hydrogen, which is passed through a system of traps (Fig. 1, not shown) which dehydrate the gas and remove any residual oxygen before it is fed into the fuel compartment 36 through the inlet 39 and engages a platinum-palladium catalyst on the anode 32. The exit stream 40 of water and unreacted hydrogen is returned to a water tap for further dehydration and then recycled. Electrodes 31, 32 are assembled about an asbestos spacer 33 saturated with electrolyte such as KOH. The hydrogenoxygen mixture is produced by the electrolysis of water or from the radiation decomposition of water with radio-active materials such as nuclear reactor fission by-products. A battery of fuel cells has the gas mixture passed serially through the cathode compartments of each cell and then serially through the anode compartments.

Abstract: 731,598. Moulding corrugated fibro-cement slabs. MAGNANI, A. Sept. 6, 1951 [Sept. 20, 1950], No: 21107/51. Class 87 (2). A plastic slab 26, which may be formed as described in Specification 731,597, [Group VIII], is fed by a belt 29 on to a corrugated mould on a carriage 31. The slab is carried to a press 32 having a corrugated pressing plunger which is moved down to corrugate the slab. Flexible, e.g. rubber, linings 34, 34', Fig. 3, are placed between the corrugating elements 33, 33<1> and the slab. These linings tend to prevent cracks in the slabs by holding the material together at the convex part of the corrugations. To assist in this action strips of canvas 36, Fig. 6, may be applied to linings on their inner surfaces at the concave parts of the corrugations and on their outer surfaces at the convex portions. The linings may be held in position by suction applied through holes 59 in the elements 33, 33<1>. As the upper elements are lowered, motors 39 rotate screw-threaded shafts 38, engaging nuts 40, to bring the elements 33, 331 towards each other in a horizontal plane. After moulding, the carriage is moved beneath a suction hoist 49 which lifts the slab, moves along transverse rails, and then deposits the slab on another carriage (see Fig. 2, not shown). A further carriage is provided adjacent to this latter carriage for supplying sheet metal corrugated matrices which are positioned between the moulded corrugated sheets. During removal of the slab the suction is cut off and compressed air may be supplied through the holes 39.
