Title: Apparatus for dispensing articles
IPC: G07F11/06
Filed: 1968-09-18
Abstract: 1,209,239. Dispensing articles. CAPTAIN INTERNATIONAL INDUSTRIES Ltd. 18 Sept., 1968 [21 June, 1968], No. 44242/68. Heading A4T. An article dispensing apparatus comprises a plurality of vertically aligned shelves 13, each mounted on a rod 16 for rotational movement from a horizontal article-supporting position to a vertical non-supporting position, each shelf being latched horizontally by a pin 22 extending laterally therefrom received in a partition aperture 25. A control bar 40 provided with an actuating arm 41 for each shelf initially has its lowermost arm 41C supported on pin 22 of the lowermost shelf 13C, its next arm 41B spaced a distance H above its pin 22 and the nth arm 41 spaced a distance (n - 1)H above its pin. During the first cycle, bar 40 oscillates and arm 41C pushes a flange 14 on the shelf 13C against a spring (20, Fig. 1), so that pin 22 is released and the shelf 13C falls to its vertical position (see Fig. 3). Bar 40 then drops down till arm 41B rests on its pin 22, and shelf 13B is released during the next cycle. After the top shelf 13A is released, bar 40 falls until a portion 44 thereof engages a stop 51. For dispensing tall articles, one or more of the intermediate shelves may initially be vertical (see Fig. 4), and after releasing the lowermost shelf, the bar drops down till one of its arms rests upon the pin of the next higher shelf that happens to be in the horizontal position. Bar 40 is oscillated by a solenoid switch 47 which moves a clamp 46 mounted on and offset portion 45 of the bar, horizontally, and a return spring 50 is provided. Between each pair of shelves is a deflector arrangement comprising integral rear and side deflectors 30, 31. The rear deflector 30 extends above the shelf below when the latter is vertical to prevent articles falling from a shelf above from hitting a lower shelf or shelves; the side deflectors 31 prevent articles falling from a shelf above from hitting the actuating arms 41 associated with the lower shelves, and the arms 41 from engaging articles on the shelves during horizontal movement of the arms on oscillation of bar 40.

Abstract: 1,109,633. Screw gauges. A. J. JONES. Feb. 18, 1965 [Oct.31, 1964], No.44521/64. Heading G1M. [Also in Division F2] A device for applying screw gauges to screw threaded members to be gauged includes a rotatably mounted worm gear h mated with a rotatably mounted worm-wheel j, the worm gear being arranged to be selectively rotated by fluid means in either direction and the worm-wheel being arranged to rotatably drive, via an adjustable torque coupling l, means capable of carrying screw gauges. In the embodiment illustrated the worm gear h is rotatably mounted on a shaft which carries a vaned rotor member g at each extremity. The torque coupling is provided by a torsion plate l which is held in adjustable engagement with the worm -wheel j by a sleeve m threaded to the shaft k. Compressed air is introduced through connection member a and channels b into valve chambers c. Each valve chamber has a poppet valve d such that when either of the valves is open air flows through channels f to impinge upon the vanes of rotors g to cause rotation of the worm gear h. When the shaft k is connected to a screw gauge in position against a screw thread under test, the housings h' and 12 are moved relatively to open a valve d and so rotate the shaft k through worm gear h. When gauging is completed the housings are again moved relatively to open the other valve d to reverse the rotors and drive of shaft k which thus withdraws screw gauge.

Title: Carriages for automatic rail-less transportation systems
IPC: B62D1/28
Filed: 1970-09-24
Abstract: 1309420 Automatic control of vehicles BURO PATENT AG 24 Sept 1970 [24 Sept 1969] 45616/70 Heading G3R A carriage for a rail-less transport system is steered along a track by devices which respond to deviations from the course and adjust the relative speeds of left-hand and right-hand driving wheels. Fig. 2 shows the underside of a goods vehicle which is normally moved in the direction shown by traction wheels 6a, 6b driven at the same speeds by electric motors 20a, 20b respectively. A desired course may be determined by a magnetic, inductive or optical strip (not shown) set in the road surface to influence detectors 22, 23, 24 at the front of the vehicle. The strip is approximately half the width of the spacing between detectors 23, 24 which are on each side of the strip as the vehicle travels along. On deviation from course, movement of the detectors relative to the strip varies the frequencies of oscillators the outputs of which operate relays through filters to de-energize or brake the appropriate motor to turn the vehicle back on to course. Both motors are stopped if the vehicle is thrown completely off course. Two trailing non-driven wheels 5a, 5b are arranged to swivel and a bar 11 operates switches 12a, 12b to stop the motors if the vehicle meets an obstruction. Alternatively, obstructions may be detected by echo sounding. A further set of detectors may be mounted at the rear of the vehicle to control backward travel. Magnetically operated switches 30-35 respond to permanent magnets suitably positioned in the road near V-junctions in the strip so that one or other motor is de-energized or braked by short circuit if it is necessary for the vehicle to turn to follow a route pre-set on a control panel (not shown) on the vehicle. In a modification, the traction wheels are near the centre of the vehicle with a trailing wheel at the front and rear. In this arrangement a continuously operating motor is coupled to one or other or both traction wheels by control of electromagnetically operated clutches and brakes or a differential gear. The Specification also refers to (a) other detector arrangements which increase the speed of one motor to turn the vehicle (b) various systems of coding to select a route to be followed or a floor to be attained (c) capacitive, inductive or optical elements instead of permanent magnets (d) interruption of the strip at the junctions.
