Abstract: 510,054. Endless-chain conveyers. GRAY, C. J., and GUINNESS, SON & CO., Ltd., A. Aug. 20, 1938, No. 24577. [Class 78 (i)] [Also in Group I] A hop picking machine of the type in which each bine, after being cut from the plant, is carried upon an endless belt conveyer which draws it lengthwise past one or more series of moving picker fingers has the conveyer provided .with jaws which automatically grip the bines to carry them past the fingers and automatically release them after passage through the machine. The machine comprises a conveyer having a pair of spaced apart parallel chains 1 between which transverse bars 2 extend, these bars carrying sets of jaws each pair of jaws consisting of a member 8 carried by a bracket 8a fixed to the rod 2 and a member 9 carried by a sleeve 9a sliding on the rod 2 but guided thereon by a pin extending from the rod riding in a slot 11 in the sleeve. The butt of a bine is laid in V-shaped slots 17 in brackets carried by the frame of the machine and as the jaws are moved by the chains 1 up to the slots 17 the member 9 is retracted against the pressure of a spring 13 by a stop 14 engaging a cam surface 18, the butt of the bine entering the jaws thus opened. Further movement of the chains 1 causes the closing of the jaws to grip the bine and to draw it through the picking devices, the picked bine being withdrawn, by rubber rollers or similar devices when the jaws are opened again.

Abstract: 1383026 Automatic circuit-breakers ARROW-HART Inc 25 May 1972 [27 May 1971] 24605/72 Heading H1N A circuit-breaker comprises a latch assembly having first and second axially movable elements 20, 22 coaxially disposed and normally abutting, resilient means urging the elements together, a thermally responsive overload device 23 connected to the second element 22 to rotate it to release the abutting engagement between the elements 20, 22 to cause opening of the contacts 34... 37, actuating means 16 operable along the axis of the elements to close the contacts and means 73 ... 75 to maintain the latch assembly in position to hold the contacts closed with the device 23 free from stress from the resilient means. As shown, the elements 20, 22 are slotted to form portions 45, 46 which normally abut, but under overload conditions a coiled bimetallic element 23 turns the lower element until the portions 45, 46 interleave under the bias of springs 40, 43 which open the contacts. The reduction in the spring bias acting on a ball latch 73 ... 75 allows the balls 75 to move inwardly to release the actuating member 16 and the first element 20 for upward movement to positions such the abutting relationship between the elements 20, 22 is restored when the bimetallic element 43 cools, so that the member 16 may then be depressed to reclose the contacts. An ambient temperature compensating bimetallic element 90 is connected to the member 16 and a shaft 18 carrying the first element 20, so that changes in ambient temperature cause both elements 20, 22 to be rotated to the same extent. Figs. 12 to 20 (not shown) illustrate a simpler construction having a single pair of contacts.

Title: A vacuum switch assembly
IPC: H02H7/22
Filed: 1970-05-21
Abstract: 1285283 Protective arrangements; electric transmission systems TOYO DENKI SEIZO KK 21 May 1970 [22 May 1969] 24608/70 Heading H2H and H2K [Also in Division H1] The output terminals of a polyphase vacuum switch 2 are interconnected by a star-connected surge absorbing unit, each arm of which comprises a fuse 6, a resistor 5, which may be non- linear, and a discharge gap 4. Voltage surges due to current chopping in the switch are absorbed by breakdown of the gaps 4; resistor 5 then increases in value to extinguish to arc. Prolonged discharge which might be caused by a lightning strike if the usual spark gaps fail causes fuses 6 to blow. A detector circuit is provided to indicate if a fuse is blown: capacitors 7 connect each arm to a neutral point, which is connected by a rectifier 8 to a capacitor 9 whose other terminal is earthed. Any D.C. voltage across the capacitor 9 is detected by a further breakdown device 10 and relay 11. This circuit also detects any unbalance in the system or if one of the individual vacuum switches has a poor vacuum.

Title: Method of refining vegetable and animal oils
Inventor: KOEBNER ADOLF
IPC: C11B3/00
Filed: 1962-06-27
Abstract: Vegetable and animal oils are purified by mixing with a dilute aqueous solution of an alkali together with a hydrotrope which is either urea or an alkali or alkaline earth metal salt of an aryl or alkyl aryl (e.g. C1-C8 alkyl) sulphonic acid, allowing the mixture to separate into an aqueous soap layer and an oily layer and removing the aqueous layer.  The hydrotrope may be used in an amount of 1-3% wt. of the oil for every unit of acid value of the crude oil and the proportion of hydrotrope to water 40-60% wt.  After removal of the aqueous layer the oil may be treated with a further quantity of hydrotrope in aqueous solution. Phosphatides present are extracted into the aqueous layer and may be recovered.  In a preferred embodiment the aqueous layer is boiled with sufficient alkali to hydrolyse any glyceride oil and a mineral acid is added to obtain a fatty acid layer which is recovered. Salts may then be crystallized from the aqueous layer and the latter recycled.

Abstract: 918,492. Centrifugal compressors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 22, 1959 [Aug. 1, 1958], No. 24889/58. Class 110 (1). In a multi-stage centrifugal compressor plant, a number of intercoolers are associated with successive compression stages and are located in parallel flow paths around the axis of the compressor, so that the air discharged from each compression stage is passed through a pair of intercoolers in parallel and the pair of intercoolers associated with at least one pair of successive stages are located in a common transverse plane. The rotor in Fig. 1 comprises six impellers, 4-9, mounted back-toback in pairs on a shaft 10.

Title: Improvements in or relating to restraint means and to shut-down apparatus for nuclear reactors employing such means

Filed: 1959-07-20
Abstract: 903,288. Magnetic holding devices. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 5, 1960 [July 20, 1959; Nov. 26, 1959], Nos. 24923/59 and 40169/59. Class 35. [Also in Group XL (a)] Restraint means for releasably restraining a multiplicity of discrete bodies containing magnetic material from passage along a tube comprises magnetic means interposed in the tube, the magnetic means including at least one pair of part annular polepieces of opposite polarity forming between them a passage for the bodies in register with the tube, the magnetic means when energized serving to restrain the bodies and when demagnetized releasing the bodies for movement along the passage. Fig. 2 shows a cross-section of a restraint means for suspending a number of boron steel balls above the core of a nuclear reactor and, in an emergency, allowing them to fall into the core and shut down the reactor. Six part annular polepieces 2 are joined to a tubular member by webs 3 around which coils 5 are disposed. Adjacent edges of polepieces 2 have interposed between them fillets 6 of non-magnetic material which preserve continuity of the internal surface, and adjacent polepieces are energized to be of opposite polarity. A central baffle 10 may be provided to exclude balls from the area of minimum magnetic field. The coils 5 of adjacent or opposite polepieces may be fed from a common circuit, and it may be arranged that two of the three circuits must be interrupted before the balls can be released. To overcome residual magnetism in the balls and polepieces alternating current of varying strength may be applied to the coils on interruption of the direct current supply. In another arrangement, Figs. 3 and 4 (not shown), the webs 3 are replaced by nickel inserts spacing the polepieces from the tubular member; with this construction if the temperature of the reactor rises excessively the nickel is heated above its Curi point and increases the reluctance of the electromagnets sufficiently to allow release of the balls. The polepieces may alternatively be permanent magnets of material and that when the Curie temperature is exceeded the magnetic flux is reduced sufficiently to allow the balls to drop. Specifications 857,432, 897,455, 897,456 and 903,289 are referred to.
