Title: Improvements in or relating to a method of and apparatus for magnetically recording and/or playing back sound
IPC: G11B21/04
Filed: 1959-03-31
Abstract: 913,487. Magnetic sheet-recording &c. apparatus. NAKAMATSU, Y. March 31, 1959 [April 1, 1958; Sept. 30, 1958; Oct. 22, 1958], No. 10920/59. Class 40 (2). A sheet record, Fig. 16, with visible representations on one side and a region 44 available for recording on the other, is located by means 46 under a transparent pressure plate on a machine, Fig. 12, which has a pair of record/ playback heads 10 driven by epicyclic gearing 28 such that each head executes a track of the form of Fig. 15, the two tracks being interlaced. To reduce cross-talk on play-back, when the heads reach cross-over points in the tracks, slip-ring means, Fig. 11, may apply two levels of recording bias, according as the heads are moving towards or away from the record centre, which is stated to isolate the respective recordings. Auto-stopping means halt the machine when a complete tour of the heads has been completed and indicating means 37, visible through the pressure-plate are provided. The two heads 10 may both be fed with the same signal, or with the two parts of a binaural signal. In other embodiments, a mechanism, Fig. 5, may produce a track, Fig. 2, more closely related to a rectangular record sheet or alternatively, successive loops may be traced on a wide tape, Fig. 10.

Abstract: 324,583. Churchill Machine Tool Co., Ltd., and Asbridge, H. H., (Wrench, J. M. D.). April 9, 1929. Rollers and the like, treating. -In a grinding machine, particularly for grinding a locomotive crank-pin s, wherein the grinding-wheel r is mounted in a head a which is rotated by a gear ring d to carry the wheel bodily round the work, the grinding-spindle is mounted in a hollow arm p supported in a bracket q on a slide e and is directly driven by an electric motor o mounted on the arm p. The slide may be fed radially in the head by means of a spindle f driven by bevel gears h, spindle j and spur gears k from a central spindle n. The grinding-spindle is inclined to the head axis and its periphery is correspondingly bevelled to engage correctly with the work. The motor is supplied by means of brush gear from conductors concentric with the spindle n and the head a is carried on a slide which is movable to traverse the wheel along the work.

Title: Means for heat treating gears by high frequency induction heating
Inventor: FROST LEONARD FRANK
IPC: H05B6/02
Filed: 1955-04-15
Abstract: 831,270. Induction heating. DELAPENA & SON Ltd. April 13, 1956 [April 15, 1955], No. 10962/55. Class 39(3) The apparatus for heat treating a toothed convex surface of an article by high frequency induction heating, described in Specification 831,269, includes adjustable means whereby the apparatus can deal with helical gears of different helix angles as well as with gearwheels having straight spur teeth. A helical gear wheel being heat treated is caused to travel past an inductor by a device 36 comprising a pinion 37 secured to a gearwheel mounting shaft 14, the pinion engaging a toothed rack 38 horizontally slidable in a crosshead 19 which moves axially with the mounting shaft. An arm 39 carries a roller 40 which engages in a slot 45 diametrically formed in a face 42a of a drum 42 journalled for adjustment about a horizontal axis. The drum is provided with a graduated dial plate 41 and is angularly adjustable by a manually rotatable worm 44 which engages gear teeth 43 on the drum. With the slot 45 set at the appropriate angle for a helical gearwheel being treated, upward or downward movement of the mounting shaft 14 causes vertical movement of the rack 38 and its roller 40, the rack and roller also being moved transversely as a result of the movement of the roller in the slot 45 set at an angle. The pinion 37 and shaft 14 are thus rotated and each tooth space of the gearwheel is positively guided past the inductor. A lock pin for engaging in a series of tapered holes enables the drum 42 to be set rapidly to the position in which the slot 45 is vertical, i.e. when a gearwheel having straight spur teeth is to be treated and to positions frequently used for helical gearwheels. Instead of the rack and pinion device, the required movement may be obtained by means of a flexible metal tape or tapes wound or unwound on a drum. Specifications 714,488, 775,463 and 813,113 also are referred to.

Title: Shuttle car mechanism for transferring loads between two stations
IPC: B65G47/52
Filed: 1973-03-07
Abstract: 1423611 Chain driven load transfer system A-T-O Inc 7 March 1973 [8 March 1972] 11075/73 Heading B7L [Also in Division A4] A transfer mechanism, e.g. for transferring loads from a supply conveyer 14 to means 10 for placing the loads in a rack structure 2 or for returning the loads to a discharge conveyer 16, comprises a shuttle car 24, Fig. 5, on rails 12a, 12b, a load support bed 36 arranged to be raised or lowered on links 68, 74 to pick up or set down a load, a linear driving member, e.g. a chain 80, attached to the car 24, and means 18 for cooperating with means 88, 90 on the car 24 to pivot the links 68, 74 to pick up or set down the load at respective ends of the path of the car 24. The chain 80 may be endlessly trained over sprockets 82, 84 one of which is driven by a motor 86, and engages around sprocket wheels 46, 48, 50 of the car 24 so that movement of the chain 80 moves the car 24 between its end positions. Raising or lowering of the bed 36 is effected by pivoting the wheel 46 to turn a respective one of the links 74, this pivoting being actuated by movement of the wheel 48 to pull the chain 80 about the wheel 46. With the bed 36 located below the conveyer 14, as movement of the car 24 towards the rack structure 2 is started a cam follower 88 engages a portion 98 of a cam 92, causing the shaft 54 bearing the wheel 48 to pivot anti-clockwise as seen in Figs. 6B and 9. The resultant relative movement between the car 24 and chain 80 causes the wheel 46 to turn clockwise, thus raising the bed 36 on the links 74 to pick up any load suitably positioned on the conveyer 14. Approaching the rack structure 2, a second cam follower 90 runs over a pivotable tripper arm portion 98 of a cam 94, so that the car 24 is located with the load adjacent support means 8a, and on reversing the car movement, the arm portion 98 is struck by the follower 90, the follower in this direction being constrained to rotate, so that the links 74 pivot to lower the bed 36, depositing the load on the means 8a as the car moves away. Approaching the conveyer 14, the follower 88 runs over the cam 92, which pivots in this direction, the bed 36 remaining in lowered position as it runs in below the conveyor, and on reversing the car 24, the cam follower 90 is engaged by the cam 92, raising the bed 36 to pick up a further load. Transfer from the rack structure 2 to the discharge conveyer is controlled by analogous cam means.
