Title: Fish handling machinery
IPC: B07C5/12
Filed: 1975-06-10
Abstract: 1505073 Orienting fish on a conveyer belt AGRICULTURE FISHERIES & FOOD MINISTER OF 10 June 1975 [3 June 1974] 24522/74 Heading B8A [Also in Division G1] A machine for grading fish according to size and for orienting them has a conveyer belt 1 which moves the fish past light sources 4 and corresponding detectors 3; the sources are at differing heights above the belt, so that the number of light beams broken by a fish depends on its thickness. A fish which breaks all the beams is directed to shoot 7 by a pistonoperated arm 6, while fish or debris which break only the lower beam are directed to a further shoot (not shown) by a similar arm 9. Intermediate fish size, which break two beams, pass both these arms and reach an orienting station where two sources 11 and detectors 12 determine whether the fish is moving head or tail first, by determining which of the beams from the sources 11 is broken first. If the fish is moving tail first it is rotated through 180 degrees by arm 13, or by a tunnel-like device 21, Fig. 2. The fish then falls through shoot 14 to the edge of a conveyer 2 where its reflectivity is measured by a further source and detector 16 to see if it is belly or back up. If necessary, it is pushed across the belt by arm 17 so that all fish travel with their bellies facing the centre line of the belt. The fish are then fed to shoots 18 which spiral in opposite senses so that a stream of similar size fish emerge, head first and belly up, from the common end of the shoots. The machine is continuously sprayed with water. If the Fig. 2 tunnel damages the fish, rubber skirts may be fitted to the tunnel.

Title: Improvements in apparatus for generating combustion gases under pressure
IPC: F02K7/02
Filed: 1932-09-03
Abstract: 387,617. Generating combustion products under pressure. CERNOCH, J., 409, Prague-Brevnov, Prague. Sept. 3, 1932, No. 24603. Convention date, Sept. 4, 1931. [Class 51 (i).] For propelling aircraft and other vehicles, a series of combustion chambers is arranged around a valve which controls the inlet to and outlet therefrom, the valve being stationary and some or all of its passages, which conduct the combustion products to one or more exhaust nozzles, being at such an angle to the radial direction that the reaction pressures automatically rotate the series of chambers about the valve. The outer casing 1 comprises a series of eight chambers divided by hollow partitions 11 into combustion spaces 10<1> and compression spaces 10<11> connected by comparatively narrow passages 12, the spaces communicating with ports 13, 14. The casing rotates on a ball bearing 18 about a conical valve 2 which has an ignition passage 23 provided with a sparking plug 29, Fig. 6, and communicating through a passage 22 with a discharge nozzle 35, the passage 23 connecting in rotation diametrically opposite combustion chambers through the ports 13. Later in the cycle the ports 13 from the same two chambers communicate through inclined passages 24, Fig. 7, with subsidiary passages 25 leading to the discharge nozzle at a reduced pressure. The inclined passages 24 ensure the continued rotation of the casing 1. Later still in the cycle diametrically opposite ports 14 communicate with a passage 26 which has a passage 27 leading to the nozzle. The ejector action of the main discharge passage 22 and the subsidiary passages 25 on the passage 27 ultimately reduces the pressure in the chambers 1011, 101 as the ports 13 come opposite passages 34 in the valve and fresh mixture is drawn in to the chambers from spaces 40 provided with air holes 42 and supplied with fuel through passages 41, Fig. 9. As the cycle continues, transfer passages connect two pairs of adjacent ports 14 to transfer pressure gases from two chambers just ignited to the compression spaces 10<11> of two following chambers, the partitions 11 preventing undue mixing of the gases. For starting, air is admitted through passages 45 and valves 46 to inclined passages 47 parallel to the passages 24. Cooling fluid is circulated through the valve through passages 43.

Title: Improvements in the manufacture of electric capacitors
Inventor: SHEN TZU EN
IPC: H01G4/18
Filed: 1953-09-07
Abstract: 758,197. Capacitors. BRITISH DIELECTRIC RESEARCH, Ltd. Sept. 7, 1954 [Sept. 7, 1953; Feb. 18, 1954], Nos. 24643/53 and 4839/54. Class 37. In the manufacture of a capacitor having a di-electric comprising a synthetic organic thermoplastic material the finished capacitor assembly is subjected to penetrating ionizing irradiation to produce cross linking of the molecules of the diametric material. The diametric material is in the form of thin layers and may consist of polythene; polystyrene, polyethylene terephthalate or nylon while high energy electrons, X-rays, neutrons or gamma rays may be used for the ionizing irradiation. The di-electric layer may be coated with a thin deposit of metal to form the electrodes of the capacitor or alternatively electrodes in the form of metal foils may be used. The metal deposit may be sufficiently thin to provide a self-healing property. Irradiation may take place in vacuum or in an inert atmosphere when the irradiation would otherwise tend to cause oxidation or to increase di-electric losses. When irradiating large capacitors the capacitors may be rotated either continuously or intermittently to ensure a more uniform irradiation. It is stated that the invention is applicable to rolled-type and stacked capacitors. The capacitor may be impregnated with silicone oil and encased in a cold-setting epoxy resin.
