Abstract: 1,086,562. Synchronizing. BLACKSTONE & CO. Ltd. April 22, 1964 [April 3, 1963], No. 13199/63. Heading H2H. A synchronizing system for two alternating current circuits comprises an operating coil OC of a circuit breaker which is energized to connect the two circuits in parallel only when the two circuits are in phase with one another. The primary winding of a transformer T1 is connected in one phase SY of one A.C. circuit and to a corresponding phase AY of the incoming circuit. Whilst the two phases are out of synchronism a transistor TR1 is held conductive thereby rendering inoperative a pulse generating circuit comprising transistors TR2, TR3 so that a silicon controlled rectifier SCR1 is held on-conductive and in consequence the circuit breaker operating coil is not energized. When synchronism of the two A.C. circuits is attained no output appears at the secondary winding of transformer T1, the transistor TR1 becomes non-conductive, the pulse generator generates pulses causing the controlled rectifier to conduct thereby energizing the coil OC whereupon the circuit breaker closes to parallel the two A.C. circuits. The system may include means preventing the pulse generator from becoming operative until the two A.C. circuits have been in synchronism for a predetermined period.

Abstract: 1502114 Extruding at specified temperatures SOC DE VENTE DE L'ALUMINIUM PECHINEY 3 April 1975 [4 April 1974] 13649/75 Headings B3P B3V and B3Q A method of shaping an alloy at a higher than normal forming ratio and/or speed and with reduced tool wear comprises heating the alloy to a temperature between the solidus and liquidus points until less than 40% by weight of the alloy has liquefied, maintaining the temperature for between 5 minutes and 4 hours so that the solid dentritic phase has at least begun to change into a globular form, Fig. 2 (not shown), and working the alloy in this condition. Profiles of various section, bar, wire and tubes may be formed by operations such as drawings, extrusion, rolling, stamping, swaging and forging. The heat treatment permanently modifies the alloy structures so that a billet cooled after the heat treatment may have the improved, "rheotropic" working properties restored merely by heating to the solidus-liquidus range. In an example aluminium alloy billets were heated to 585-605 C. for 15 minutes to give a liquid content of 6-13%. The billets were extruded from a container heated to 420- 450 C., through a water-cooled die at an exit temperature of 450 C. Tests were carried out immediately after extrusion, after ageing for 8 hours at 175 C. and following water quenching after 2 hours at 505 C. and the above ageing. In numerous other aluminium alloy examples temperatures ranged between 572-625 C., times between 15 and 30 minutes and liquid content between 4 and 25%. The work may be cooled with air or water as it issues from a die to solidify substantially all of the liquid fraction.

Abstract: 1478433 Automatic circuit breakers MERLIN GERIN 3 April 1975 [12 April 1974] 13798/75 Heading H1N An operating mechanism for a circuit breaker which performs a cycle of opening and closing a circuit without intermediate resetting comprises a first crank arm 22 on a shaft 18. which operates the contacts of the circuit breaker and is latched by a latch 64, and a second crank arm 20 on a shaft 16 adapted to be operated by a control member and latched by a latch 62, both crank arms being mounted between parallel plates 12 and connected by a lost motion connection rod 48 so that the interconnections between the crank arms, side plates and connection rod lie at the apices of a quadrilateral which has one side of variable length and which is deformed under the action of a single compression spring 36 inserted between the crank arms and having a different line of action from the connection rod, this spring providing the energy to perform the opening and closing cycle. The spring 36 passes over a guiding bar 38 one of whose ends is rotatably mounted on the second crank arm and whose other end is rotatably and slidably mounted on the first crank arm. Opening and closing of the circuit breaker are produced by reciprocating rotation of the first crank arm 22, release of latch 64 to free crank arm 22 allowing anticlockwise rotation of the crank arm 22 under the influence of spring 36 to close the contacts, the second crank arm 20 being blocked during this time by latch 62, whilst when latch 62 is released it allows crank arm 20 to rotate in a clockwise direction to drive crank arm 22 through rod 48 to open the contacts. The latches 62, 64 are controlled by solenoid or manual control. Resetting after the cycle is manual or automatic. An interlock arrangement may be provided, Fig. 5 not shown, to control the latches causing opening and closing of the circuit.

Abstract: 1,261,793. Electro-photographic processes. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. March 17, 1969, No. 13898/69. Heading G2H An electro-photographic process, particularly for producing continuous tone images on a plate 10, Fig. 1 or 20, Fig. 2, comprises the steps of uniformly charging the top surfaces 14 or 25 of photo-conductive layers 13 or 24 respectively before exposure and uniformly charging the back surfaces 15 or 26 of insulating layers 11 or 21 respectively with the same polarity before or after exposure, to a light image, and developing the electrostatic latent image to produce a visible image. The layer 11, Fig. 1, may be of polethylene terephthalate, cellulose diacetate, or cellulose triacetate. A conductive layer 12 may be of aluminium, brass, titanium, copper, copper iodide, metal salt or conductive glass. The layer 13 may be of selenium, sulphur, anthracene, zinc oxide in a binder or brominated poly-n-vinylcarbazole. The layer 23, Fig. 2, may be polyvinyl acetate or vinylidene chloride/acrylonitrile acetate maleic anhydride terpolymer while the conductive layer 22 and insulating layer 21 are similar to the layers 11 and 12 Fig. 1. In operation of the process, Figs.3A-3D (not shown) the plate 10, Fig. 1, is charged, exposed, charged on the back surface to a potential at least twice the mean valve on the surface 14, and then developed by immersion in a liquid developer. In another embodiment Figs. 4A-4C (not shown) the surfaces (14) and (15) are charged simultaneously. The positive charge on layer 13 becomes reduced in exposed areas, thus reducing the electric field on the top surface in proportion to the exposure which the field is uncharged in unexposed areas. Positively charged toner particles deposit in the exposed areas to produce reversal development.

Abstract: 755,612. X-ray tubes. METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 18, 1954 [May 18, 1953], No. 13930/53. Class 39 (1). [Also in Group XX] In an X-ray tube having a cathode 3, and a rotating anode 6 coupled to a rotor 8 with a corresponding stator winding 9 outside the envelope, at least that part of the envelope surrounding the rotor and also the anodecathode discharge path is of metal, of which at least that part surrounding the rotor is non- magnetic. This non-magnetic section 15a should have sufficient resistivity to avoid imparing the efficiency of the motor; thus copper and brass are stated to be unsuitable, and stainless steel is suggested. The metallic section 15b is of such material as will seal to the glass section 14. Inwardly projecting baffles 17 protect the glass section from the discharge. Sections 15a and 15b may be in one piece if the metal is suitable for both purposes; alternatively the entire envelope may be of the non-magnetic metal. The metal envelope may have cooling fins 20 of copper or aluminium; by forming these obliquely instead of radially, and sandwiching slats of lead between them, the structure can also act as a protective shield. A casing 19 guides the flow of cooling air from a fan 18. In Fig. 3, the glass section of the tube projects into the oil- or gas-filled casing 21 of a high voltage generator. In this case the whole structure 21 must move bodily with the tube; a suitable mounting frame, Fig. 8 (not shown), allows a multiplicity of translational and rotational movements.
