Filed: 1972-03-01
Abstract: 1379313 Cinematography EASTMAN KODAK CO 1 March 1972 [1 March 1971] 9545/72 Heading G2E In a reel-to-reel web handling apparatus e.g. a cine projection, a flanged supply reel 10 carrying film F is supported on a vertical shaft 26 to which is applied a retarding force by a slip clutch, the magnitude of the force being dependent on the weight of the film F on the reel 10. As shown in Fig.3 a drive belt 78 rotates a pulley 70 abutted by thrust washers 72, 74 and held axially by plate 68 and ring 76. A lower clutch ring 104 having a friction surface 106 has slots 108 aligned with prongs 90 and a further slot (110), Fig.2 (not shown) aligned with a key 86 on the pulley 70. A retaining ring 92 holds the clutch ring 104 and pulley 70 together. Upper clutch ring 98 is attached to shaft 26 and contacts surface 106. A cap 112 fitted with prongs 114 passing through slots 102 is biased by spring 118 so that the prongs 15 urge the clutch rings 98, 104 together, the force being dependent on the weight of the film F on the reel 10. For reverse winding the clutch is by-passed by energizing solenoid 124 which moves the cap 112 upwards so that prongs engage the flat rather than the inclined faces of wedges 84. The drive therefore passes from the pulley 70 via prongs 114 to clutch ring 98 and hence to spindle 26.

Title: Improvements in or relating to electrically controlled indicators for weighing scales
IPC: G01G23/36
Filed: 1947-04-11
Abstract: 652,674. Electric indicating systems. SCHEMBER & SOHNE, BRUCKENWAAGEN-UND MASCHINENFABRIKEN AKT.-GES., C. April 11, 1947, No. 9653. Convention date, July 31, 1946. [Class 40 (i)] An electrically-operated indicator for a weighing machine is actuated by denominational members mechanically set according to the load which each mark a corresponding contact in the bank of a stepping switch which is stepped automatically after being manually started, and when it reaches the marked contact sends impulses to the corresponding denomination of the indicator synchronously with the subsequent steps of the switch to zero position. The weight to be measured is applied at A and balanced by the pendulous mass D pivoted at C, which through an arm E, sector gear G and pinion F rotates the shaft W through an angle corresponding to the weight. The shaft W carries stepped discs H, one for each weight indicator denomination units, tens, hundreds, &c., each of which has a corresponding number of steps co-operating with a spring-biassed key M. On being manually released at N, each denominational key M moves to engage the associated disc edge and at the same time closes the corresponding contact pair of a contact bank P to mark the associated contact 0, 1, 2 ... of a switch bank 47 corresponding to the angular position of the stepped disc H. A switch 23 is then momentarily closed to initiate stepping of a rotary switch having three contact banks 22, 46, 47, the switch continuing to rotate by interaction of the stepping magnet 10 with a relay 24 until it has made half a revolution. When the wiper 20 reaches the marked contact in bank 47, contact number 5, for example a relay 25, is energized, locks over the bank rail 22 and causes impulses, in the present case six in number, to be delivered synchronously with the advance of wiper 20 over bank 46 and line 45 to the stepping magnet 30 which steps the indicator shaft 36 to indicate 5. The indication may in known manner be printed by means 39 for each denomination. The indicator is zeroized after each weighing by throwing a switch 40 for each denomination to the right or left respectively for successive weighing operations, whereupon a relay 41 interacts with the stepping magnet 30 to advance the indicator shaft 36 to normal.
