Title: Continuously expandable switching network
IPC: H04Q3/545
Filed: 1978-01-17
Abstract: In this continuously expandable modular switching network, incoming traffic infiltrates the network only to the extent required in order to set up the desired connection. For an extension involving additional switching matrices (110, 112, 113) in two stages, there is no need to alter the internal or external connection lines. A technique is employed in which the outputs (104, 106) of the switching elements of any given stage (stage 1) are connected only to the inputs of switching elements of higher-order stages (stage 2). So-called reversal points (114, 116, 118, 120) of the aforementioned second stage are used to switch a connection. <IMAGE>

Abstract: 139,260. Paulin, J. G. Jan. 24, 1919. Pitot-tube apparatus. -In ships' logs of the Pitot-tube type in which the movement of a diaphragm controls a rheostat in an indicating-circuit, the resistances of the rheostat are so spaced relatively to each other that the tension or intensity of the current varies directly as the speed of the vessel. A pipe 1 communicates the pressure in the Pitot-tube to diaphragm chambers 2, 3, and a pipe 4 the hydrostatic pressure to chambers 5, 6. These chambers are rigidly attached to the opposite sides of a plate 7 and are connected to a frame 8, 9, 10, which moves according to the difference of pressure in the two sets of chambers.

Abstract: 1,078,042. Twin lens reflex cameras. J. KREBS. Jan. 17, 1966 [Oct. 8, 1965], No.2170/66. Heading G2A. [Also in Division G1] A twin lens reflex camera having a built in spot photo-meter, which barrel projects from the 23, 30 each having a lens associated therewith. The chamber 23 contains a diagonal mirror 33 which reflects light from the viewing lens 21 on to a ground glass screen 31 at which the camera user looks, the screen being protected by a foldable hood 32. The chamber 23 further contains a constant intensity light source 39 and an optical system which directs a spot of light from the source on to the screen 31 through an opening 49 in the mirror, relatively movable optical wedges 51 being provided in the light path to regulate the brightness of the comparison spot on the screen. A white or yellow disc 60 or 63 may be shifted into the spot light path for outdoor or indoor lighting, as is also an e.g. middle brightness range disc 66 for e. g. a scene of medium brightness. Once these discs have been positioned in the spot light path (by external control means, Fig. 2 (not shown)) and a circuit through the source close by depressing a button (59) Fig. 6 (not shown), a ring (58) is rotated so as to adjust (via gearing (52-56) Figs. 6, 8) the optical wedges 51 until the comparison spot is seen to have the same light intensity as the adjacent view finder image area on the screen 31. A choice of lens aperture versus shutter speed is then read from scales on the barrel (71) of the photo-meter is divided into two chambers the side of the camera. A photo-electric cell 40 energized by the source 39 is provided, which cell supplies current to a galvanometer which may be connected to the camera. The galvanometer indicates that a mercury battery (72) (Fig. 6) and the source 39 are operational. A rheostat (74) in the source circuit can be adjusted if either source or battery is slightly weakened.

Abstract: 638,242. Rotary disc valves. TRICO PRODUCTS CORPORATION. Jan. 26, 1948, No. 2333. Convention date, Jan. 27, 1947. [Class 135] [Also in Groups XXVIII and XXXII] A valve for controlling the raising and lowering of a vehicle hood by a pneumatic jack, is used to connect one side of the piston to a source of low pressure, i.e. the engine inlet manifold and the other side to a source of high pressure obtained from a pump having two opposed pistons of unequal area and driven from the same source of low pressure, the pump itself also being started and stopped by the valve. The inlet manifold is connected to the low pressure chamber 52 via the conduit 12 and the pump is connected to the pressure chamber 48 via inlet 13. Conduits 8 and 9 are connected to the pneumatic jack on opposite sides of the piston and conduit 17 is connected to the driving side of the pump for supplying compressed air. When shaft 50 is turned platevalve 49 uncovers one of ports 47 in communication with conduits 8, 9, thus allowing compressed air to the jack on one side of the piston whilst the other side is in communication with the inlet manifold via passage 51 and lowpressure chamber 52, rotation of shaft 50 also causing plate-valve 58 to uncover port 57 connected to the inlet manifold via conduit 12.

Abstract: A normally solid thermoplastic vinyl aromatic polymer has intimately incorporated throughout 0.01-2% of saturated aliphatic monocarboxylic acid which comprises at least 75% of one or more acids containing 22-25 carbon atoms.  The polymer may be polystyrene or a copolymer of 70-80% styrene and 30-20% acrylonitrile.  The acid may be behenic, tricosanoic, tetracosanoic or pentacosanoic and may contain not more than 25% of a C18- 20 acid, e.g. a commercial behenic acid which contains 80% of C22, 12% C20 and 8% C17 or C18 aliphatic monocarboxylic acids. The composition may be produced by polymerizing styrene in the presence of behenic acid using specified time/temperature conditions or by heat plastifying the polymer in admixture with the molten acid.  In a comparative example stearic acid was used in place of behenic acid.  The composition may be formed into articles, e.g. bottle caps or film.

Title: Improvements in and relating to dry cleaning
IPC: D06L1/08
Filed: 1935-01-25
Abstract: In a process for dry-cleaning clothes in which both grease and water-soluble stains are removed, the clothes are first treated with an organic solvent containing wax, fat, oil or similar substance to render the clothes water-repellant <PICT:0437491/III/1> and are then treated with an organic solvent containing water. Water-repellant substances specified are, paraffin wax, fatty acid glycerides, castor or cocoanut oil.  One or more of these are mixed with a solvent such as gasoline, naphtha, carbon tetrachloride, or trichlorethylene together with a dispersing agent such as ethylene glycol mono butyl ether.  Gasoline or other solvent is pumped from a tank 1 through a filter 4 to a mixer 5 to which is added the mixture of water-repellant substances and dispersing agent.  The resulting solution circulates through a washing machine 7, a strainer 12 which retains buttons, pins, &c. and through a filter 4 to the washer 7. Circulation is continued until all the dirt is removed and deposited in the filter and the solution is clear as viewed through a sight glass 15.  A mixture of water, a little alcohol and a dispersing agent are then admitted to the solvent from a tank 19 and is dispersed in the solvent by the pump 3 and the filter 4 from which it is circulated through the washing chamber.  The water may also be dispersed by a mechanical homogenizer without the aid of dispersing agents.  The clothes are then removed, freed from solvent and dried. Suitable water dispersing agents are triethanolamine, anhydrous propyl or methyl alcohol, cyclohexanol or a filter aid.  The used solution may be decolorized by treatment with carbon.  Specifications 289,582, [Class 91], and 401,752 are referred to.
