Title: Improvements in or relating to electric cut-outs and controlling devices
IPC: H02J7/22
Filed: 1931-08-12
Abstract: 384,708. Electromagnetic switches and interrupters. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Ald. wych, London, and GRIFFITHS, L., Kennington, Biggin Hall Crescent, Coventry. Aug. 12, 1931, No. 22793. [Class 38 (v).] A combined electromagnetic cut-out and vibrating regulator for use on motor vehicles has the resistance controlled by the regulator contacts mounted within the baseplate on which the cut-out and regulator is supported. As shown in Fig. 1 the insulating baseplate 6 carries the combined cut-out and regulator consisting of a core 1 with shunt and series windings 3 and an armature 4 carried by a blade spring 14a attached to the yoke piece 1a. The armature carries one of the cut-out contacts 10 which on attraction first engages the cooperating cut-out contact 11 thus completing the charging or other circuit. On further attraction the armature by distorting the spring-blade structure 12, 14 separates the regulator contacts 7, 8 so inserting the resistance 9 in the battery or dynamo field circuit. This resistance is carried on a support 9a held under the securing nut for the core 1 so that the resistance is contained within a cavity formed in the lower face of the insulating, baseplate 6. In a modified form, Fig. 2, (not shown) the movable regulator contact is carried by a separate blade spring support which is engaged by an insulating projection on the armature after the cut-out contacts have been closed.

Abstract: 1,190,421. Radiographic screens. THORN ELECTRICAL INDUSTRIES Ltd. 17 May, 1967, No. 22891/67. Addition to 1,185,832. Heading H5R. [Also in Divisions C4 and H1] An electroluminescent device as in the parent Specification has incorporated in the electroluminescent material, or in the path of light passing from this material to the outside of the device a dystuff or other colouring material serving to increase the contrast between light and dark areas of the image. The colouring material may be a separate layer between the conductive film and electroluminescent layer, or a transparent coloured layer over the outside of the glass or plastics member. With a green electroluminescent phosphor, the colouring material may be methyl violet dissolved in a 10% cyanoethyl cellulose solution in a 1: 1 mixture of acetone and formdimethylamide and applied by spraying, dipping or spinning technique to the front glass surface to form a 0À005 inch thick layer. With blue and yellow phosphors, Lacquer Orange G and Oil Soluble Black respectively may be used or other dyes with a maximum spectral absorption close to the main emission of the phosphors. Alternatively the glass may be tinted e.g. neutral grey, a neutral grey filter may be incorporated in the panel or provided as an accessory such as a sleeve for viewing purposes.

Title: Crane load indicating arrangement
IPC: B66C13/50
Filed: 1973-05-16
Abstract: 1463811 Crane load indicating arrangement PYE Ltd 15 March 1974 [16 May 1973] 23233/73 Heading G1N A load indicating arrangement similar to that of Specification 1462785 is disclosed but the indication here is of total effective load defined as the weight at the hook of the actual load plus the total weight of a structure, acting through its centre of gravity, which supports the load i.e. in the latter respect, an equivalent weight at the hook which produces the same turning moment as the weight of the structure acting through its centre of gravity. The indication is derived by dividing the signal M which is proportional to the total turning moment of the boom about its pivot by the signal TR representing the load radius. Meter 58 is operative to indicate available lifting capacity or overload as the case may be in terms of total effective load at the hook.

Title: Improvements in and relating to forming apparatus for profile grinding wheels
IPC: B24B53/08
Filed: 1957-07-23
Abstract: 824,735. Trueing grinding wheels. HALLEWELL, H. S. July 18, 1958 [July 23, 1957], No. 23355/57. Class 60. Apparatus for forming the profile of a grinding wheel 15 on a horizontal spindle of a surface grinding machine comprises a carriage 21 adjustable by screw-threaded means, 30, 31, 32 on a base 17, and a pantograph mechanism 50 ... 53 which has a tracer member 58 mounted on one side of a fixed pivot 54 on the carriage for cooperation with a template 39 adapted to be supported on the carriage and a follower member 59 mounted on the opposite side of the fixed pivot and serving to support a tool 61, the follower member depending below the base to permit the apparatus to be mounted above the spindle of the grinding machine with the tracer and follower members on opposite sides of the spindle. The base 17 may be mounted on a bracket on-the machine column or on the bearing box 13 for the spindle and has guideways provided with rectilinear antifriction bearings for the carriage 21 which is movable thereby in a direction transverse to the axis of the grinding wheel by rotation of a handwheel-controlled screw 30 engaging a wheel 31 formed as a nut on the second screw 32 axially secured to the carriage ; a fibre plunger moved by a screw 28 provides a light clamping pressure to prevent vibratory movement of the carriage. The carriage has at one end a platform 36 on which the template 39 is clamped by screws 40 and adjusted by a screw 38. The tracer 58 is carried in a bearing housing 56 which is supported by an arm 52 forming one member of the pantograph 50 ... 53 movable about the pivot 54 fixed to the carriage ; one or both of links 51, 53 may be mounted on the pivot 54. The follower member, in the form of a rotatable arm 59, depends from the pantograph and carries the diamond tool 61 with its point coincident with the axis of rotation of the arm and in the horizontal plane containing the axis of the grinding wheel. Links 62, 64 and a bell-crank lever 63 connect the arm to the tracer member 58 so that rotational movements necessary to keep the tracer normal to the contour 41 of the template are imparted to the tool 61 to keep it normal to the surface of the grinding wheel. A hollow water jacket 19 may be interposed between the base 17 and bearing box 13 to prevent transfer of heat from the latter to the apparatus ; the jacket has a' guideway 18 in which the base is adjustably secured. The Provisional Specification refers to the follower member supporting a tool or tools and to Specification 573,877.

Patent GB-248277-A (GB)
Title: Improvements in or relating to combined powdered-fuel and grate furnaces
IPC: F23C1/00
Filed: 1925-09-19
Abstract: 248,277. Hold, C. Sept. 19, 1925. Pulverulent-fuel furnaces. - In a furnace heated by burnt pulverulent-fuel burnt in suspension and also bv fuel on a grate the combustion chamber i has a dome-shaped roof k merging downwardly into a wall curved in horizontal section and the powdered fuel is drawn in by a vacuum created in the chamber. The flame can be directed towards any part of the solid-fuel grate a by separately regulable secondary air supply conduits r. Inferior solid fuel is supplied from bunkers b through shoots c to the travelling grate a and the powdered fuel is delivered by a spiral conveyer e from a bunker d to an air-supply pipe h adjustably throttled by a device p so that a suction is caused which, with the suction of the chimney, draws the fuel and air mixture through burners g into the combustion chamber. The shape of the combustion chamber induces a whirling motion of the flame and focusses the radiated heat at the ignition zone. Air is drawn by a fan m into a jacket l surrounding the combustion chamber and is forced into the primary air supply pipe h and a secondary air supply conduit o from which the separately regulable branches q, r enter the chamber i at various angles. The pipes q enter the chamber around the burners g and are used when burning powdered fuel of low carbon content to give the flame a wide arc. For rich fuels the pipes r are used giving a horizontal flame. By adjusting the secondary air supply the flame may be directed upon any part of the grate a, and when only the grate fire burns, without powdered fuel, preheated air can be directed to every part of it. Conduits s supply preheated air underneath the grate, and the throat-arch t is kept at firing heat by the powdered fuel flame, ensuring complete combustion of the inferior fuel. Specifications 226,131 and 233,214 are referred to.
