Title: Improvements in or relating to electric motors
IPC: H02K17/16
Filed: 1938-08-22
Abstract: 518,315. Alternating-current motors. GENERAL ELECTRIC CO., Ltd. and JACOBY, H. C. E. Aug. 22,'1938, No. 24675. [Class 35] In a rotor, especially for a synchronous squirrelcage motor, the conductors, or some of them, are so arranged that, for at least a part of their length, the portion of them furthest from the axis is in close contact with the magnetic material of the rotor, while portions nearer the axis are in contact with air or other non-magnetic material.

Title: Coin released mechanism
IPC: G07F9/04
Filed: 1970-05-21
Abstract: 1,273,886. Coin-freed vending machines. KENSON Ltd. 21 May, 1970 [4 June, 1969], No. 24772/70. Heading G4V. A vending machine is formed from a plurality of cassettes in which insertion of the one or more coins required into the slot of a cassette allows a drawer to be pulled out, thereby presenting the lowest object in a stack. Alternatively the purchaser may press the drawer in to regain the purchase price. In an embodiment in which two coins are required per article the coins fall into slot (32, Fig. 5, not shown) cut in drawer (13) transversely to the direction of movement, the first coin, 29, resting on an outer rib member 16 and an inner rib member 17 secured to shelf 10 below the drawer, and the second coin, 30, is supported by rib 17 and the cut-out edge portion 22 of pivoted cam plate 20. Cam plate 20 carries an upstanding projection 23 which normally limits the withdrawal of the drawer by abutting against the teeth of rack 24 secured to the underside of the drawer, but on withdrawal of a drawer containing coins 29 and 30, cam 20 is rotated out of the path of rack 24 by the action of coin 30 on surface 22a, thereby freeing the drawer. A cam plate protection member (36) prevents plate 20 being fraudulently held away from rack 24.  The customer may secure the return of his coins by pressing the drawer inwards against springs 43 so that the coins are brought over notches 18, 19 in central rib 17 and thus fall into a coin return shoot. Notch 19 extends nearer to the free end of rib 17 than does notch 18 so that the mechanism actuating coin 30 is returned first, thus preventing fraud. Instead of notches 18, 19 the spacings between rib 17 and rib 16 and edge 22 may be increased adjacent to shelf 10. Embodiments (Figs. 9, 10, not shown) requiring the insertion of 1 and 3 coins respectively are also described. A coin shoot (60, Figs. 11-13, not shown) for testing the diameter of the coins comprises an inclined bottom plate (61), two convergent side plates (63) and an inclined top plate (64). The width of the shoot is slightly larger than the diameter of the coins required and the bottom plate (61) is provided with a coin reject hole (66) the diameter of which is slightly less than the diameter of the coins being used. An elongated slot (67) is provided in the top plate to enable valid coins to fall into the vertical shoot (8).

The return end of the band may be secured to the bar 7. The yoke crosses the front face of the band and is cranked to form a looped extension 14 serving as a finger-grip or as a holder for a finger-tab. The yoke is adapted to be turned down in either direction so as to enclose the slide and lie flat on the band. In a modification only one wide bar 4 is provided, the ends 10 are mounted in apertures in the flanges 3 and the return end of the band is secured to a sleeve mounted on inturned lugs integral with the flanges 3. The yoke may be formed with bearing holes engaging fixed pivots on the slide.

Abstract: 738,924. Knitting-machines. LAMBACH, F. Sept. 16, 1953 [Oct. 8, 1952], No. 25616/53. Class 74 (2). Each welt rod 436 of a straight-bar machine has its ends retained in supports 432 by pivoted plates 438 so shaped that when they are operated at a predetermined interval they release the rod to let it fall on to the knitted fabric, Fig. 10, and then are further operated to force the ends of the rod out of their supports 432 into a guideway 314, Fig. 11, where they are engaged by welt rod hooks on straps to be taken up by the draw-off mechanism. The plates 438 are controlled through linkage from a cam on a cam-shaft. The fabric draw-off mechanism comprises pawl and ratchet mechanism at each end of the machine for driving the take-up rollers to which are attached the take-up straps. The drive from the shaft 192 of the machine effecting motion of the needles is transmitted to the ratchet arm 178 to urge the arm in its reverse direction against the pull of a spring 180, the spring 180 sufficing to impart the necessary takeup motion to the ratchet wheel 168. The connection between each ratchet and take-up roller is through a torsion spring 170, 171 one of which is stronger than the other so that by bluffing the ratchet mechanism associated with the stronger spring the tension of the take up can be varied. Specification 686,302 is referred to.
