Abstract: 1300947 Rotary switches; variable resistors CTS CORP 23 Sept 1969 [23 Sept 1968] 46818/69 Headings H1N and HIS [Also in Divisions F2 and H3] A control device has an actuator 23, 43 carrying a first contact 44, the actuator is biased to a neutral position by a resilient means 36 and when the actuator 23, 43 is moved in one direction from the neutral position by an applying force it first engages the first and second contacts 44,38, the second contact being constrained to move with a control member 34, 22, and then it operates the control member 34, 22 which performs a control function such as varying a resistance 17, 21 and on removing the applying force the actuator 23 is returned to its neutral position by the resilient means 36. On initial rotation of a shaft 23 by an applying force in either direction switch contact 44 on the actuator 23 contacts one of the contacts 38. Then continued rotation causes drive members 34, 22 to rotate adjusting the position of a slider 21 on a resistance film or wire wound track 17 of a variable resistor 11. On removal of the applying force the actuator 43 and shaft 23 are returned to the neutral position by a spring wire 36 and the switch contacts 38, 44 open but the position of the slider 21 remains unchanged. In a modification (Figs. 5-8, not shown), the actuator (144) is biased to its neutral position by a body of resilient material (135) mounted within a cavity (126b) in the control drive member (126). In a further modification (Fig. 9, not shown) the resilient material is replaced by a steel spring (235). The control device may be of rectilinear type. The variable resistance may be used in a radio or TV for volume control.

Sheets are fed to a duplicating or folding machine from a table 12, Fig. 1, having laterallyadjustable rails 30 for engaging the sides of the sheet pile, and fingers 68, Fig. 3, which rest upon the corners of the top sheet so as to ensure that only a single sheet is fed at a time, the fingers being movable laterally with the rails 30 and vertically with respect to the rails, and can be raised by a finger lever 102 mounted on one of the rails 30 to permit of the insertion of a fresh pile of sheets. The fingers 68 are slidably mounted on a rod 46 which is movable vertically in slots 53, Fig. 5, in laterally-offset extensions 38 of the rails 30. One arm 60, Fig. 10, of a bracket carrying each finger is extended upwardly and carries a pin 70 movable in the slot 53 in one of the extensions 38 so as to maintain the finger 68 in a position where it slopes upwardly and rearwardly. The pin 70 has collars 72, 74, 78 thereon which are of greater diameter than the width of the slot 53, but the centre collar 74 can be slid laterally through an enlarged part 54, Fig. 5, at the top of the slot. Thus, the fingers when raised can be moved lengthwise of the rod 46 into one of two positions, one for engaging square-cornered sheets, Fig. 3, and the other for engaging roundcornered sheets (Fig. 4). The lever 102 raises the fingers against the action of gravity and has a forked end for engaging either the collar 72 or the collar 74 according to the transverse position of the fingers. Suspended from the centre of the rod 46 is a post 52 serving as an abutment for the front of the pile, the post being raised when the fingers are raised. The post is maintained in its vertical position by a link (90, Figs. 2, 7) pivoted to the bottom end of the post and to the underside of the table. Slots 96 are provided in the horizontal flanges 26 of the guide rails 30, and the table 12 has a trough 98, to receive feed-wheels (30, Fig. 8) which drop into the trough when the last sheet has been fed and cause the sheet feed mechanism to be stopped. Friction elements 100, Fig. 1, on the flanges 26 retard sliding movement of the bottom sheet of a pile.
