Abstract: 826,972. Conveyers. KING Ltd., G. W. July 5, 1957 [July 10, 1956], No. 21325/56. Class 104 (2). In a conveyer system which comprises a curved track 10 along which load-carrying trolleys run a quadrant 14 pivots above and at the centre of curvature of the track and carries plate or strip elements which propel the trolleys in one direction and move vertically upwardly out of engagement with the trolleys on the reverse movement of the elements. An arm 17 driven by a geared motor reciprocates the quadrant which has rollers 15 running on a track 16 fixed to the track 10 and a bracket 18 carrying the elements 20 between rails 19. Each element has a peg 21 resting on a rail 19 and a chamfered edge which when it engages a trolley during the reverse movement of the quadrant raises the element out of engagement with the trolley. Stops preventing rearward movement of the trolleys comprise elements 22 mounted in groups between fixed rails 23 above the track 10. The elements have a peg 24 and chamfered edge which allows them to ride over the trolleys as they move forwardly. A separate reciprocating carrier 26 supporting a number of upwardly displaceable elements may propel trolleys on a straight part 12 of the track, the carrier may be hinged to the quadrant to move therewith.

Title: Method of sorting and sorting apparatus
Inventor: CHAPMAN THOMAS HENRY
IPC: G01N27/02
Filed: 1969-04-25
Abstract: 1279134 Sorting, measuring physical properties electrically GUNSONS SORTEX Ltd 23 April 1970 [25 April 1969] 21341/69 Heading G1N In apparatus for sorting objects, the objects are conveyed, e.g. in free fall or on a conveyor, through a coil 16 or a capacitor mounted in the tuned circuit of an oscillator 18, the objects being sorted e.g. by a pneumatic or mechanical ejector 22, by the effect they have on the tuned circuit. As shown in Fig. 2, the tuned circuit 16, 28, 30, 32 forms part of a Colpitts oscillator and upon a damping of the oscillator tunnel circuit due to an object, a positive going signal is applied via line 50 and integrating amplifiers 52, 54 to the base of a transistor 56. When a signal is applied to the base which is sufficient to trigger transistor 56, a transistor 66 provides an amplified output which operates the ejector 22 to displace the object causing such a signal. A differentiating device (70) may be interposed between the oscillator and the amplifiers 52, 54 so that a signal having a magnitude dependent upon the rate of change of the signal on line 50 is applied to the base of transistor 56, Fig.3 (not shown). In a modification, Fig. 4 (not shown), a photocell (72) is provided to sense the presence of an object, the photo-cell output and the transistor 56 being connected to a gate circuit (76) for operating the ejector. In addition, a property of each object, e.g. the reflectivity, may control the sorting in addition to the damping effect.

Title: Steering column electric switch for direction indicators
IPC: B60Q1/42
Filed: 1961-06-15
Abstract: 930,875. Electric switches. SWF-SPEZIAL-FABRIK FUER AUTOZUPEHOER GUSTAV RAU G.m.b.H. June 15, 1961 [Aug. 6, 1960], No. 21587/61. Class 38 (5). A direction indicator electric switch disposed below a steering wheel comprises a casing 1, a first ring 5 forming a continuation of the easing and rotatably mounted about the column 4 so as to operate a direction indicator contact bridge 7, a manuallyoperated lever 6 connected to the ring 5 and also a ring 9 which is mounted so as to be able to tilt about a pivot 8 and operate a dip-switch 11 mounted within the casing. The pivot bolt 8 connects the lever 6 with the ring 5, the lever being extended into the ring 9, which has an enlargement at 10, opposite the pivot bolt. Upward movement of the lever depresses ring section 10 and thus a slide 12 of a dip switch, to cause a projection 24 on one of two guide bars 14, 14<SP>1</SP> to bear on a flat surface of a block 16 and to rotate the block through 90 degrees on an axle 17, causing a contact bridge 19 cooperating with two separate contacts 20, 21, and a " common " contact 23, to rotate similarly and " change over " its contact arrangement. Simultaneously, the guide bars 14, 141 are mutually spread by the block 16, against the tension of spring 15, the slide being returned, on release of hand lever pressure, by the action of a spring 25. Movement of slide 12 is limited by spring 28 which may itself constitute a contact, so that heavy slide pressure causes the spring 28 to make contact with a further spring contact 29 for headlamp flashing.
