Filed: 1954-05-07
Abstract: 771,077. Gas turbine plant. NAPIER & SON, Ltd., D. April 27, 1955 [May 7, 1954], No. 13467/54. Class 110 (3). [Also in Group XXIX] A gas turbine plant comprising a compressor A<SP>1</SP> driven by a turbine rotor C and an independent output turbine rotor D for driving a propeller E, or a helicopter rotor, has auxiliary means H responsive to the relative speeds of turbine rotors C, D to control the fuel supply to combustion chambers B so that when little or no power is required to maintain the propeller E at a particular speed, the speed of the turbine rotor C and compressor A<SP>1</SP> is maintained within the range of speed at which they rotate under normal level flight conditions. The object of the means H is to render the engine capable of developing immediate substantial power when it is working under low power, e.g. when landing. Centrifugal pumps F, G are driven by the shafts of the rotors C, D, respectively, and supply through conduits F<SP>1</SP>, G<SP>1</SP> fluid pressure to each side of a diaphragm J<SP>1</SP> which is connected to a rod J<SP>2</SP> which operates a valve K which controls the pressure fluid supply to a servo-piston M<SP>1</SP> which operates through a rod M4 and a lever N a control lever O of a fuel pump O<SP>1</SP> such that when the speed of the rotor C drops relative to that of the rotor D the diaphragm J<SP>1</SP> moves to the right causing the valve K to move to the right and allow pressure fluid from a conduit L to act on the left-hand side of the piston M<SP>1</SP> moving to the right and so setting the pump O<SP>1</SP> to supply more fuel to increase the speed of the rotor C. The pump O<SP>1</SP> and a propeller governor Q can be operated manually through a rod P and a rod R<SP>3</SP> operated through a rod R<SP>2</SP> can push the diaphragm J<SP>1</SP> to the left to cut down the fuel supply, e.g. for starting or idling.

Title: Improvements in or relating to the preservation of foodstuffs, tobacco and other perishable commodities
IPC: A23L3/3418
Filed: 1934-05-05
Abstract: 430,053. Preserving food, tobacco, and other perishable commodities. DUTTWEILER, G., R³tiweg, R³schlikon, and LANZ, P., 10, Langmauerstrasse, Zurich, both in Switzerland. May 5, 1934, No. 13651. [Classes 49 and 130] In a continuous process for preserving food, tobacco, cigars, cigarettes, and other perishable commodites in tins, bottles, or other receptacles, the open tins 5 are introduced successively into a container 1 filled with carbon dioxide at ordinary pressure and are moved to a discharge point at a rate which ensures they remain sufficiently long in the container for automatic displacement of their air content by gravitational inflow of the carbon dioxide, the receptacles being afterwards sealed in the outer air. Pulverulent materials such as milk powder, coffee beans, ground coffee and nuts which require longer for saturation with carbon dioxide may be filled within the container into the tins, e.g. through a pipe having one or more branches by which carbon dioxide is supplied and mixed with the commodity during the filling. Alternatively, the commodity may be agitated in a closed receptacle charged with a neutral gas such as nitrogen and then filled directly into tins in the container 1. A similar treatment, excluding the agitation, may be used for cigarettes and cigars. Mealstuffs and other pulverulent materials may, with or without the preliminary treatment with neutral gas, be compressed into cubes before packing in the tins. The preliminary treatment may be used for mixing two different powders, e.g. coffee and milk powders. In sterilizing the sealed tins by heating, the transference of heat to the commodity may be increased by adding to the tins a small amount of water the repeated evaporation and condensation of which maintains a constant supply of heat. The container 1 may have a belt conveyer 4, Fig. 1, for the tins which on arrival at the delivery end are covered with lids and supplied to a sealing machine. The carbon dioxide is supplied to the container 1 through a tube 6. In another form, the container 1 is annular in shape and has a conveyer for taking the tins around it, or itself revolves being mounted on a circular rail 7, Fig. 5, which rotates on flanged rollers 8 supported from pedestals 11 which also carry a fixed cover 12 for the container 1 with an opening for supplying and removing the tins. In a modification, the revolving container is circular. In a further form, the tins are carried through the container 1, Fig. 9, which is open-topped, on holders 17 supported between one or a pair of endless chains or belts 15 passing over wheels 16 one of which has a crank handle 19 for rotating it. To enable the container 1 to take a larger number of tins it may be enlarged at the bottom along which the tins are moved horizontally or the chains or belts 15 may pass over more than two wheels 16 to give a longer path.

Title: Scanning circuits in a central telecommunication exchange
IPC: H04Q11/04
Filed: 1970-03-24
Abstract: 1,269,872. Automatic exchange systems &c. INTERNATIONAL STANDARD ELECTRIC CORP. 24 March, 1970 [31 March, 1969], No. 14114/70. Heading H4K. In a computer controlled PCM, TDM exchange, data in respect of a change of state e.g. new call or new signal, of an incoming channel is stored in a buffer which is read-out on demand by the central processor. The buffer has four compartments which are utilized on a cyclic basis. Two compartments store data in respect of new calls while the other two store data in respect of new signals. The provision of two compartments for each data type allows scanning of incoming trunks to continue with insertion of resultant data in one compartment while the processor is reading-out data from the other of the two compartments. The processor may interrupt scanning so as to obtain direct information as to the state of a particular channel. The scanning is effected by circuitry described in Specifications 1,269,888 and 1,269,901, the buffer being additional to this circuitry for making better use of the scanning and processing facilities in a large exchange. The switching network is of the type described in Specification 1,261,599. The buffer may be duplicated with the two sections working alternately, or simultaneously with the results being compared, or simultaneously with one in an active mode and the other in a checking/ stand-by mode.

Filed: 1972-03-25
Abstract: 1396364 Jet dyeing machine SAMUEL PEGG & SON LTD 26 March 1973 [25 March 1972] 14132/72 Heading D1L Apparatus for dyeing textile material in endless rope or open width form comprises a closed treatment vessel formed by a loop of pipe 1 and cylindrical chamber 2, dye liquor nozzle means including a first jet inlet 6 and auxiliary jet inlet 7, means including circulating pump 4, heat exchanger 5 and control valves 6a and 7a for feeding dye liquor to the jet inlets to drive textile material round the vessel, and metering means including rotatable roller 17 (Fig 3), deflector roller 21 and sensing switch 20 connected to calibrated ammeter 23 for measuring the speed of travel of the material through the vessel. As illustrated the cloth metering device is preferably positioned in jet housing 16 between inlets 6 and 7, metering roller 17 being hollow and formed with a plurality of longitudinal ribs on its surface and a permanent magnet 19 secured to the inside of its cylindrical wall. In use the textile material 18 is forced round the treatment vessel in the direction indicated by liquid from jet inlet 6 and, when it is desired to measure the speed of web travel, deflector roller 21 is moved by handle 30 from an inoperative position to a position (selected according to the characteristics of the material being treated) in which the material 18 is deflected into contact with metering roller 17. As roller 17 is rotated by the moving material the permanent magnet 19 modifies the waveform set up by sensing switch 20 and this modification is sensed by the associated circuitry to give a read-out of web speed on the calibrated ammeter 23. The circuitry may also include a relay 25 which controls jet control valves 6a and 7a. In normal use valve 6a is open provided that pulses are received from sensing device 20. Should the movement of material through the vessel cease, due e.g. to snaring or a blockage roller 17 cease to rotate and relay 25 causes jet 6 to stop and opens valve 7a for a predetermined time to cause treatment liquid to issue from jet 7 and thus move the material through the vessel in the opposite direction.
