Title: Improved coin-freed vending machine
IPC: G07F11/54
Filed: 1954-01-28
Abstract: 751,970. Vending apparatus. CLARKE, P. F. B. Dec. 20, 1954 [Jan. 28, 1954], No. 2670/54. Class 27 A vending machine for tub-shaped articles such as tubs of ice cream comprise a rotatable refrigerated magazine having vertical storage tubes 9, an outlet 16 through which an article is released into an apertured block 18 sliding on a wooden base 46 to deliver the article to a reception chamber 52, a coin-freed operating handle 42 linked to the block 18 and to a sliding pawl carrier 33 for indexing the magazine and, in the region of the outlet 16, rails 20, 21 extending through slots 19 in the tubes to support the article next above the released article until the tube from which the latter was released has been rotated clear of the outlet; the rails 20, 21 are curved so that the supported column of articles are lowered gradually. The pawl carrier 33 has a spring- loaded pawl 34 engageable with one of several lugs 30 corresponding to the number of storage tubes and also an abutment 53 which rocks a finger 54 into engagement with another lug 30 to prevent overrun of the magazine. An arm 36 depending from the pawl carrier is linked to the block 18 by an L-shaped rod 43 and carries a roller 37 engaging in a slot in a plate 39 on the operating handle shaft'40. The lowermost articles in the tubes ride on an arcuate rod 2<SP>3</SP> and a plate 91 having a raised portion corresponding to the rod 2<SP>3</SP> can be moved over the outlet 16 to block it when the storage tubes are being loaded. Coin action.-The operating handle shaft 40 is linked to a lever 64 carrying a coin blocking and release member 76, a coin abutment member 75 and, behind the latter, a locking member 79 having a shoulder 80. The three members extend through apertures in a coin shoot 68 but the engagement of the shoulder 80 with a wall 67 prevents movement of the lever 64 until there is a coin resting on the blocking member 76, when the cam face 75<SP>1</SP> of the member 75 rides up the coin and lifts the locking member so that the shoulder 80 is above the lower edge of the aperture for the locking member. A spring-pressed plunger 75<SP>2</SP> in the member 75 prevents the coin from falling rearwardly. As the freed lever 64 rocks forwardly, an aperture 77 in the release member 76 comes beneath the coin and allows it to fall into a coin box 70<SP>1</SP>. A lamp above the coin slot is controlled by the coin mechanism to show when the parts are in their initial position or otherwise.

Title: Improvements in or relating to methods of and apparatus for grinding flat glass on both faces simultaneously
Inventor: JAVAUX GUSTAVE
IPC: B24B57/00
Filed: 1955-01-31
Abstract: 792,824. Grinding glass. PILKINGTON BROS. Ltd. Jan. 6, 1956 [Jan. 31, 1955], No. 2850/55. Class 60. Abrasive in suspension is fed to the choked inner ends of distributing channels formed in the operating surface of each of a series of grinding discs acting upon the under face of a moving ribbon 28 of glass through the hollow driving shaft 6 of, and central cavity 17, in the disc, the choking of the inner ends of the channels providing a restricted space which adjoins the plane of the operating surface of the disc and is so related to the working pressure of the abrasive fluid that it is maintained full of the fluid. The ribbon 28 is acted upon by coaxial pairs of lower and upper discs 1, 2, each of the lower discs being carried by plates 15, 16 on the hollow shaft 6 which is driven by gearing 4, 5 arranged to permit the vertical movement of the shaft by rack-and-pinion gearing 11. The upper surface of the lower disc surrounding the cavity 17 is provided with an annular series of nobs 18 which are separated by radial distributing channels. A pan 19 having a cylindrical wall 20 is located in the cavity 17 on a tube 21 which passes down through the bore of the shaft 6 and at its lower end rests in a cup 30. Abrasive fluid is passed upwardly through the tube 21 to the pan 19 and passes over the rim of the wall 20 into the distributing channels in the disc 1; the tube 21 is carried in a bearing plate 24 which is adjustable vertically by screw-threaded studs 25 to permit setting of the rim of the wall 20 so that for a given hydrostatic head on the abrasive fluid, the space 29 between this rim and the lower face of the glass ribbon is always full of abrasive fluid, and the rim functions as a weir. The pan is preferably made as a fit in the central cavity 17, but, if it does not rotate with the disc, an anti-friction bearing is provided between the tube 21 and the spindle shaft 6. If desired, the pan 19 may consist only of a cylindrical wall with radial members connecting it to the tube 21, and in some cases the cylindrical wall is removable so as to permit its replacement by walls of progressively less height as the grinding disc wears. The glass ribbon is supported in the cavity by an abutment 33 which is mounted for vertical adjustment on a cage 34 supported on a boss 36 on the bottom of the pan. The central cavity 17 may be shaped as a circle ellipse or polygon. Specifications 267,654 [Class 60], 502,118 and 671,961 are referred to.

Title: Improvements in or relating to electromechanical transducers
IPC: G01D5/22
Filed: 1956-12-12
Abstract: 843,817. Electromagnetic transducers. CANADIAN WESTINGHOUSE CO. Ltd. Dec. 12, 1956 [Dec. 15, 1955], No. 2959/60. Divided out of 843,816. Class 40 (1). A transducer comprises two inductively coupled elements, one being a pair of separate coaxial helical conductors of the same radius and pitch having their turns alternating with one another, and the other being a helical conductor coaxial with the first and of the same pitch but of different radius. Preferably the second element also is a bifilar helix. In Fig. 2 the first element comprises a bifilar helix with connections at 6 and 8, the other ends being attached to one another at 7, and the second element is another bifilar helix with two separated windings 10-11 and 12-13. A.C. is supplied to the first element and induces in the two windings of the second element currents whose magnitudes will depend on the relative axial positions of the elements, and will also vary if the first element is rotated on its axis. Linear displacement can be measured by moving one element relative to the other and noting the number of maxima of current which occur in the second element. The fine position can be determined by rotating the first element until the current is a minimum and noting its angular movement. The transducer can also be used in the positioning system of Specification 843,816. The accuracy of the windings is improved by locating the wires in grooves on the elements. In Fig. 5 (not shown) the pick-up coil is a monofilar helix. In a further modification (Fig. 6, not shown) the bifilar helix of the pick-up coil is wound unsymmetrically, one winding being closer to the second winding on one side than the other; this gives a non-sinusoidal output with sharper nulls but it is not possible to use angular rotation of one element for fine measurements. Specification 604,382 also is referred to.
