Inventor: MATTHEWS LESLIE JOHN
IPC: G07D3/10
Filed: 1951-05-01
Abstract: 703,774. Trays for sorting coins and the like. TOOLEY, A. H. April 29, 1952 [May 1, 1951], No. 10229/51. Class 27 Sorting coins: trays. Vertical partitions 20, Figs. 6 and 7, in a coin-sorting tray guide coins or other circular discs intocorrect alignment with elongated apertures formed in the bottom of the tray and passing only coins below a limiting diameter. The tray is one of several placed one above the other, the apertures of an upper tray being larger than those of the tray beneath. In the trays of Figs. 6 and 7 the apertures are defined by rods 22 and the trays are located on one another by pins 15 which engage within the corners at the lower edge. A solid-bottom tray may be placed below the sorting trays which may be surmounted by the guide-tray shown in Fig. 3 which has partitions 16, 17 of unequal height to ensure that all coins enter the lower trays with their planes vertical. A local thickening of the partitions 20 at the level of the sorting bars 22 in the tray at Figs. 6 and 7 serves to reduce the breadth of the compartments 13 at the bottom. The vertical partitions 20 in all the trays and the partitions 16, 17 are preferably in register vertically.

Filed: 1968-03-04
Abstract: 1,223,133. Fastener driving tools. K. REICH, [trading as KARL M. REICH MASCHINENFABRIK]. 4 March, 1968 [7 March, 1967], No. 10373/68. Heading B4C. A pneumatically operated percussion device for driving fasteners, e.g. nails, or staples, comprises a valve 13 which, when actuated by depression of a pin 14, starts the percussive action, and means whereby the pin can be actuated by depression of trigger 16 only when the nose of the device is contacting a workpiece and when a nail is present in feed duct 7. The means comprises a rod 19 which has a workpiece sensing member 17, and which supports at its upper end a lever 15, and a rocker 24 spring-urged to the position shown in Fig. 1. The rocker ineludes a pin 26 which co-operates with a shoulder 31 on the rod 19 to lock the rod, and a projection 29 which is contacted when a nail is present in the duct. A nail introduced via pipe 9 will cause the rocker to pivot clockwise and the pin 26 will be disengaged from the shoulder 31 so that when the device is placed against a workpiece the rod 19 will be displaced upwardly, and cam surface 27 will engage pin 26 to cause further pivoting of the rocker in order that a safety stop 23 may be removed from the path of the nail. In order that the head of the nail may pass through restricted part of the duct 7, a part 33 is pivotally mounted at 34 and is urged by spring 35 to its normal position. A stop device 40 prevents excessive movement of the part 33 during driving of the nail. In an alternative embodiment a pivoted member (124) (Fig. 8, not shown) is of U-shape section, one limb of the U extending into the feed duct (107) and the other limb providing a projection engageable with a step on a rod (119) to lock the rod in an inoperative position, the rod when released permitting actuation of a control valve. In this embodiment nails are supplied to the feed duct from a magazine.

Abstract: 1,006,855. Circuits employing bi-stable magnetic elements. NATIONAL CASH REGISTER CO. March 12, 1964 [March 26, 1963], No. 10500/64. Heading H3B. A magnetic data storage matrix includes a plurality of wire-like devices 10, elemental regions of which can be magnetically driven to one or other of two magnetic states, each device 10 having a winding 11 coupled to all of its elemental storage regions, and the winding consisting of a coil portion 11a wound round all the storage elements, and a portion 12 extending through the device, so that the external magnetic field generated by the longitudinal component of current flowing in 11a is opposed by the magnetic field generated by portion 12. As shown, each bit wire 10 consists of a conductive, non-magnetic substrate 12 carrying a thin magnetic film 14 having a longitudinal easy axis of magnetization. The two-part sensedigit winding 11 is wound on the magnetic layer, the two winding portions being joined at 11b. In addition word windings 21 to 29, one at each storage region, are wound over the sensedigit winding. Date is read by driving a storage region to its " 0 " state by energization of a word winding. A " 1 " is written into a region by energizing winding 11 simultaneously with a word winding. If a " 0 " is to be written winding 11 is not energized. The longitudinal components of current in the two parts of winding 11 produce magnetic fields which reinforce in the region of magnetic film 14 and produce a circular field which reduces the current required to switch the magnetization of the film. In a modification portion 11a of winding 11 consists of several sections joined by conductors running parallel to the bit wire 10. The storage elements may be separate areas of magnetic coating separated by uncoated regions of substrate. The bit wire may be a hollow rod and the conductor 12 may then be an insulated conductor threaded through the bit wire. Alternatively the bit wire may be a homogeneous wire of magnetic material. Specification 1,006,856 is referred to.

The meter output drives a gear train including shaft 28 to which wheel 29 is attached. The wheel carries a pin 30 which passes through a slot in an arm 32 pivoted to the member 42 at 41. A block 37 is attached to the pin and is guided by rod 39 sliding in a projection 34, and is spring- loaded. This allows motion to be lost once the member 42 reaches the cam. The member 42 is connected via a one way clutch 44 to the counter. The gear train drives a counter directly to provide an uncorrected reading; a pointer extends from counter 50 to the cam to indicate temperature.

A cordless electric toothbrush is driven through gearing from a reversible electric motor, switching means being provided for selectively controlling the direction of rotation of the motor shaft, and the arrangement being such that rotation of the motor shaft in one direction produces axial reciprocation of an output shaft 22, to which a toothbrush is attached, and rotation of the motor shaft in the opposite direction produces rotary oscillation of the shaft 22. A pinion 60 on the motor shaft meshes a gear 62 on a fixed shaft 56. Located within an extension of the gear 62 is a cam member 63 which is engaged by a pin 67 on the gear 62. An arm 66 secured to the output shaft 22 has an elongated recess 74 which engages a pin 65 on the top of the cam member 63. The control means include a positive detent 78a which may engage between lugs 63c on the periphery of cam 63. For oscillation of shaft 22, gear 62 is driven in the direction of the arrow shown and rotates cam 63 in the same direction by virtue of pin 67 engaging a slot 75a in cam 63. The oscillation is then imparted through pin 65 and arm 66. For axial reciprocation of shaft 22, gear 62 is rotated in the opposite direction, detent 78a prevents rotation of cam 63, and oscillation is produced by the engagement of pin 67 in an endless cam groove 75 in cam 63.

The test specimen, e.g. a turbine blade 1, is clamped to the free end 41 of an elongated carrier 4 rigidly fixed at its other end 42 to a base 5, and a driving electromagnet 6, disposed adjacent the free end 41, is energized by an alternating current controlled by a pick-up 8 carried at the free end of the carrier 4 and engageable with the test specimen at a point spaced from the clamping means 2 to generate a control voltage corresponding to the amplitude of movement of the specimen. The control voltage is fed into the energizing circuit (not shown) of the electromagnet through an amplifier 9 and a phase shifter. The electromagnet 6 induces vibrations of the specimen of such magnitude that the pick-up 8 transmits signals which after amplification at 9 are used to further vibrate the specimen to maintain the resonant frequency and compensate for external influences such as temperature and fatigue of the material of the carrier 4. If the carrier is of non-magnetic material an insert 7 of iron is provided. The pick-up 8 also measures the amplitude and frequency of the vibrations.
