Abstract: 1,212,308. Endless conveyers. TOBACCO RESEARCH & DEVELOPMENT INSTITUTE Ltd. 1 April, 1969 [9 April, 1968], No. 17067/69. Heading B8A. Cigarettes are fed by an endless belt 12 into a bin 6 under the control of an arm 9 which remains in a horizontal position (Fig. 1) until the cigarettes lift a control member 13 up to a point where it engages the operating arm of a switch 14. This initiates the movement of the arm 9 in a clockwise direction and when it reaches a position corresponding to the angle of repose of the cigarettes as they accumulate on the base of the bin 7 (as shown in dot-dashlines), a switch 16 is actuated by a cam 15 so as to energize the drive of an endless conveyer 8 for discharging the bin. When the level of cigarettes in the bin drops below a photo-electric detector 18, the arm 19 is caused to rotate back in an anti-clockwise direction to the Fig. 1 position. The arm 9 has a hinged extension 11. Both the arm 19 and the member 13 may be of ladder-like form (Fig. 5, not shown). In a modification (Fig. 4) the arm 9 is replaced by an arm 20 which moves anticlockwise from a horizontal position (dot-dash lines) to the position shown in full lines. When cigarettes which are fed up a channel 31 by a rotary member 32, they deflect a member 22 into engagement with the arm of a switch 33. When the arm 20 engages a switch 36 the conveyer 8 is activated. Curtains 24 to 30 control the build-up of cigarettes in the bin.

Filed: 1944-09-20
Abstract: 583,139. Photographic copying apparatus. KODAK, Ltd. Sept. 20, 1944, No. 17924. Convention date, Oct. 5, 1943. [Class 98 (i)] Where auxiliary devices are used in photographic copying apparatus, e.g. an exposure meter or a copy plane indicator, a camera exposure or movement of the pressure platen is prevented whilst the auxiliary device is in position. The platen 12 is pivoted on bolts 18 passing through supports 11. Rods 19 are pivotally connected to the rear end of the platen and pass through a cover-plate 20 on the base-plate 10, the ends extending into the base-plate each carrying a coiled spring 21 and a knurled securing nut 22.. A pair of plates 23 with notches 24 engaging between washers 26 resiliently held on studs 25, serve as brakes for the platen member. The control for the platen is obtained by a system of linkage in which a link 32 pivoted to the platen and to a link 34 pivoted on a fixed bracket 30 is held with the platen in operative position by a roller 37 on a link 35 also pivoted at one end on a bracket 31 and attached at the other end to the plunger 41 of a solenoid 40. An insulating pin 43 on the bottom of link 32 controls switch contacts 42. Actuation of the solenoid moves the link 35 and releases the platen which is moved by the spring 21 to its inoperative position, the spring- pressed washers 26 braking the end of this movement. A vertical column 44 carries a bracket 49 upon which is pivoted an arm 46 carrying a photo-sensitive cell 45. The pivot post 48 carries on its underpart a pin 50 which engages in its rotation with a cam part 54 and closes switches 51, 52 thereby. When the cell 45 is in operative position over the copy, the switches 51, 52 are both open. The camera 55 shown diagrammatically includes an electric motor 56 which drives the shutter operating cam 59 and a switch cam 58. A solenoid 60 controls the camera switch 61. A control unit 66 includes a transformer 67, 68 and manual switches 69, 70. The master switch 72 is foot operated. Four separate circuits can be established in the apparatus, namely, the camera operating control circuit which includes the solenoid 60 and transformer secondary 68 ; the camera operating circuit passing through the switch 61 and motor 56 ; the camera control circuit through switch 52, contact arms 42, foot switch 72 and transformer primary 67 ; and the platen control circuit through platen switch 62, solenoid 40, switch 51 and manual switch 70. When the auxiliary device 45 is in operative position, the switches 51, 52 are open and break the camera control circuit and the platen control circuit. When the platen is in the inoperative position, the switch contacts 42 are open and break the camera control circuit so that the camera cannot be exposed. Operation of the camera rotates the shaft 57 and the cam 58 closes the platen-switch 62 at the end of its movement, thereby allowing the platen control circuit to be completed. Operation of the manual switch 69 shunts the switch 62 and allows the platen to be released without operation of the camera.
