Title: Improvements relating to electrified trawls
IPC: A01K75/00
Filed: 1956-06-20
Abstract: 796,941. Trawl nets. GUDJOHNSEN, H., and GUDJOHNSEN, J. June 20, 1956 [July 2, 1955], No. 19153/56. Class 48. [Also in Groups XXXV and XXXVII] An electrified trawl comprises conductors 2 held in spaced relation by non-conducting transverse connections 3 and forming therewith a net of mesh size greater than the mesh size of the bag-shaped back part of the trawl, the conductors being connected by multi-core cables 9 to a current distributer 21 supplied by an A.C. generator 20 in such manner that the conductors in successive pairs receive alternating current impulses. The net formed by the conductors and the transverse connections 3 forms the mouth of the trawl. The current from the generator is fed by slip-ring brushes 22 to sliprings 23 and then through distributer brushes 24 to the lamellae of the distributer 21. The distributer brushes 24 and the slip-rings 23 are rotated by the generator through gears 25. The width of the distributer brushes 24 is less than or equal to the width of each lamella so that only two pairs of conductors are energized simultaneously and the gears 25 are arranged so that a full wave of current is supplied to each lamella at each contact with the brush. The position of the brushes 24 is arranged relative to the armature of the generator so that the current goes through its zero value when each brush contacts only one lamella. The distributer is mounted on the hollow rotatable axle of a drum 26 on which the multicore cables 9 are wound and the cables pass through the axle to the distributer. The cables serve also as towing hawsers. The generator is driven by a D.C. motor.

Title: Improvements in or relating to the working of internal combustion engines
IPC: C10J3/46
Filed: 1926-08-05
Abstract: 256,631. Nouvelle, A. L. Aug. 5. 1925, [Convention date]. Hydrogen. - Substantially pure hydrogen intended for working internal-combustion engines is produced by decomposing water vapour which has been vaporized bv the heat of the engine exhaust, in a gas-generator by means of ignited pulverized carbon which is projected into the gas-generator in a stream of hot air, the latter being the least quantity necessary for maintaining the reaction temperature, and passing the resulting gases into an apparatus where the carbonic acid is separated from the hydrogen. The gas generator may comprise an ellipsoidal chamber of steel or nickel provided with a refractory lining. The pulverized carbon and the preheated air are introduced through concentric nozzles b, c through the former of which the pulverized carbon is supplied, and through the latter the preheated air. Water vapour is supplied through the nozzle d and the gases pass through the exit tube e to a heat interchanger which preheats the air. The carbonic acid may be separated by means of an apparatus comprising two concentric tubes, the inner one of which is porous and receives the gas mixture. A gas enriched in hydrogen passes from the outer tube. The nozzles b, being in the ignition circuit, the carbon, air, water-vapour mixture is normally fired by sparks. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of alcohol for starting the reaction. This subject-matter does not appear in the Specification as accepted.
Patent GB-183817-A (GB)
Filed: 1922-07-15
Abstract: 183,817. Doelker, E. July 29, 1921, [Convention date]. Photo-mechanical printing-surfaces; plates; developing.-Consists in a process in which a layer of natural or artificial resin, or a mixture thereof, sensitized for example with a chromate, is exposed under a negative until the portions exposed are rendered insoluble in a developer comprising (1) an alkali or a substance having an alkaline reaction, or (2) alcohol or other organic solvent containing alkalis or alkaline substances. The light-sensitiveness of the layer may be increased by adding thereto (1) carbon disulphide, either pure or containing sulphur, or (2) albumen decomposition products. Numerous examples of resins, sensitizers, and developers are given. In one example of the process, 50 to 200 grm. of a non-sticky artificial resin, fcr example a condensation product of phenol and formaldehyde, are dissolved in 1000 cc. of alcohol coloured with Schweinfurt green. 100 to 250 cc. of this solution are agitated for 1 to 5 minutes with 2 to 10 grm. of ammonium bichromate and filtered through cotton-wool. A polished zinc plate is roughened with a solution containing nitric acid and alum, rinsed, dried and warmed. The resin solution is then applied to the plate, exposure under a line or screen negative is made in sunlight for 3 to 5 minutes, and development effected with a 1 to 1.5 per cent solution of caustic potash. The plate is rinsed, dried, and warmed, and the resulting reproduction etched in fairly strong acid. Alternatively, an exposure three or four times as long is given, and development effected with a solution of 1 to 1.5 per cent of caustic alkali in alcohol or in a mixture of equal parts of alcohol and glycerine. In another example, an alcoholic solution of shellac is similarly employed. The sensitiveness of the resin layer may be increased by adding to it (1) 15 per cent of carbon disulphide, or (2) 10 per cent of a solution of albumen obtained by boiling 1 part of maize or wheat with 10 parts of alcohol under a reflux condenser for several hours. After development, the backing material may be etched, or the developed layer may be used for direct printing. The process is suitable for all photographic reproduction on non-absorbent backings in monochrome and polychrome printing, and for lithography. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification of the process, according to which organic solvents such as alcohol are used alone as developers. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Fluid-pressure Servo Adjusting Devices
IPC: F15B9/12
Filed: 1968-04-25
Abstract: 1,180,189. Fluid-pressure servomotor systems. ROBERT BOSCH G.m.b.H. April 25, 1968 [April 26, 1967], No. 19572/68. Heading G3P. A servo adjusting device comprises an output member 6 serving to adjust a mechanism 14 and having a neutral position in which it adjusts the mechanism to a particular position, the output member being slidable in a cylindrical bore 2 and having opposite faces exposed to opposed pressure chambers 8, 9, a control valve 44 guided in a bore in the output member and biased towards a mid-position in the output member by springs 60, 61 and movable from this mid-position relative to the output member for controlling the connection of the chamber 8 to a source 19 of fluid under pressure or to a pressure-free space 57, and an actuating member 11 connected with lost motion to the control valve and having a recess 41 therein which communicates with a control passage 39 only in the neutral setting of the actuating member, the recess and control passage together with recesses in the output member establishing a connection between the pressure chamber 8 and the source of fluid or the pressure-free space when the output member is displaced from its neutral position such as to move the output member to its neutral position. The mechanism 14 may be the swash-plate of a pump forming part of a hydrostatic transmission and connected through non-return valves 21, 22 to the chamber 9. When the valve 44 is displaced to the right, fluid flows from the chamber 9 into the chamber 8 through passages 52, 54 in the member 6 and an annular groove 46 in the valve 44. The member 6 is thus displaced until it is recentred with respect to the valve. If the latter is moved to the left fluid flows from the space 8 to the pressure-free space 57 through a passage 51, an annular groove 47 and passages 56, 55 until the movement of the valve has again been followed-up by the member 6. The recess 41 and the passage 39 connect the chamber 8 with the chamber 9 through a passage 36 when a land 30 on the member 6 is to the right of a groove 38 and with the pressure-free space 57 through a groove 37 when the land is to the left of the groove. The member 6 is thus set to a precise neutral position. The device may be used to position a machine part, to control conveyer or an I.C. engine or a quantity ratio in a feeder or to operate a lifting or pivoting arrangement on a vehicle. The valve 44 may be operated by a lever through a crank and connecting rod.
