Title: Improvements in or relating to methods and machines for grinding crankshafts
Inventor: LEVESLEY ERIC
IPC: B24B5/42
Filed: 1968-08-27
Abstract: 1,216,207. Grinding crank-shafts. ENGLISH STEEL CORP. Ltd. 15 Aug., 1969 [27 Aug., 1968], No. 40802/68. Heading B3D.  A method of grinding a crank-shaft comprises mounting the crank-shaft 3 non-rotatably in supports 2 leaving free access all round a crankpin 18 to be ground, driving a flexible abrasive belt 22 by means of one of a pair of pulleys 21A, 21B between which the belt is trained with the abrasive surface facing outwards, orbiting the belt and pulleys round the crank-pin, and moving one of the pulleys towards the crank-pin to cause contact between the crank-pin and belt where the latter is in contact with the pulley. In a machine for carrying out the method, the crank-shaft is secured by split bearings 15 to the supports 2 which are mounted on adjustable cross-slides 6 carried by saddles 4 interconnected by a shaft 5 for movement in unison on a base 1. A frame 7 straddles the base and rotatably supports an annular carrier 8 having guideways 19 for a radially adjustable slide 20A. An electric motor 24 drives one of the pulleys 21B and the other pulley 21A is mounted on a plate 29 which is adjustable about the axis of pulley 21B to bring the abrasive belt 22 entrained about the pulleys into engagement with the crank-pin 18, the plate being fixable in adjusted position by a bolt 30 passing through an arcuate slot 31 in the plate 29. A jockey pulley 23 is provided for tensioning the belt. In operation, the crankshaft is mounted on the supports 2 and the pulley 21A adjusted to engage the belt with the crank-pin. The carrier is rotated so that the belt orbits the crank-pin as it is driven over the pulleys by the motor 24 which receives its power from contacts 27 co-operating with rings 26. The crank-shaft is moved axially so that the belt traverses the crank-pin by a motor 9 driving a lead screw 12 to move the saddles 4 along the base 1. A second slide 20B may carry means for grinding and polishing the faces of the crank webs. The grinding may be effected wet, a pump, supply pipes and drain circulating coolant which is cleaned by a centrifuge or magnetic separator.

Abstract: 1,165,004. Tape cassette. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. 26 Sept., 1966 [27 Sept., 1965], No. 40960/65. Heading G5R. A tape cassette for a magnetic tape recorder comprises a pair of spools 14, 15 mounted in a shallow synthetic plastics box having three straight sides 11-13 and a further side interrupted by a gap across which the tape passes between the spools. The spools are located by spigots which pass through circular holes in the base and/or lid of the box and holes 19-21 co-operate with pins in the recorder to locate the cassette on a mechanism platform in the recorder to which it is secured by spring clips engaging the lid of the cassette through aperture 22. Spaces 25, 26 contain arms (not shown) which secure the spools when the cassette is removed from the recorder. The cassette is formed with a dovetail slot 23 into which a " write permit " plate can be inserted. This can close a switch in the recorder which energizes a " write " amplifier and allows recording to proceed. Removal of the plate prevents new matter being accidentally recorded over previously recorded matter.

Abstract: 1522604 Bundling T W JESTY V E JESTY and E R DEAKIN [trading as T W JESTY & PARTNERS] 19 Sept 1975 [20 Sept 1974] 41108/74 Heading B8C Apparatus for forming bundles, e.g. of water cress or flowers comprises means for locating a strip 49 of wire reinforced bundling material adjacent a station 11 at which bundles of cress; &c., are inserted, means 12 movable about the station so as to move a portion of the strip 49 around the inserted bunch and means for restraining an opposite end part of the strip 49 to enable the strip to form a loop around the bunch. Portions of the strip 49 are cut from a supply by a cutting device 35, and a rotary disc 42 is operable to twist the ends of the loop together. With a strip portion in position, Fig. 1, a bunch is inserted into a recess in a base plate 10 defining the station by hand, a plate 100 being depressed against a spring 97 by contact with the operator's hand. A cam member 98 on a plunger 99 bearing the plate 100 actuates a logic valve 53 controlling a pneumatic ram 16, a resultant stroke of the ram 16 causing the means 12 to pivot about a mounting and pull the end of the strip 49, retained by a bight 47, around the bunch. The trailing end of the strip portion is retained by an aperture 42B in the disc 42 through which it passes, and the leading end is inserted by the means 12 into a bight 42A in the disc 42. Further logic valves (56), (57), Figs. 4 and 9 (not shown), are operative on actuation of the valve 53 to operate a further ram 37, which advances a cutting blade 38 to cut off the portion of the strip 49 and then to actuate a ram 46, which advances a rack 44. The disc 42 is thus rotated through a pinion 43 to twist together the ends of the strip portion. Simultaneously, completion of the stroke of the means 12 actuates a logic valve 19 to cause retraction of a ram 30 of a strip feeding means. The means 12 is then retracted under the control of a logic valve 54, the bundle being ejected by a finger portion 14, whereupon the ram 30 is operable to advance a rack 29C to drive a feed roller arrangement 24, which feeds the strip through a guide 39 and the aperture 42B into engagement with the bight 47.

Abstract: 1318399 Radio navigation MARCONI CO Ltd 27 Aug 1970 [1 Sept 1969] 41269/70 Heading H4D In an arrangement for sequentially connecting a plurality of loads to an R.F. source, the current-time modulation characteristic "blending function" of the R.F. during connection of a load is in the form of three cosine lobes. The invention is applied to a Doppler V.O.R. beacon, to reduce degradation of bearing accuracy due to undesired amplitude and phase modulation of the transmitted signals. It is stated that a (sin X)/X function is known to be the optimum but is difficult to generate. If n is the number of elements in a circular Coppler V.O.R. array, the blending function may consist of a first cosine lobe of period 2T, where T = 1/(30n) seconds, flanked by second and third cosine lobes each of period T and of the same phase as each other but of opposite phase to the first lobe.
