Title: Slide projector

Filed: 1971-09-23
Abstract: 1322455 Optical projection apparatus EASTMAN KODAK CO 23 Sept 1971 [24 Sept 1970] 44350/71 Heading G2A In a slide projection a control circuit for controlling the stepwise movement of a slide magazine transporting mechanism emits pulses of a given duration to cause stepwise movement in a forward direction and longer pulses which return the magazine 17 to a predetermined position. As shown terminals 1, 2 connected to the secondary winding of a transformer lead to a rectifier 3 fitted with a smoothing capacitor 4. Relays 8, 9 and then contact 10, 11, 21 are shown in the position for forward movement of the magazine 17. For a further movement in this direction switch 7 is closed to create a pulse which is transmitted via terminal 14 to move the magazine transports mechanism forwardly one step. However, closure of switch 15 which provides a longer pulse activates delay circuit 22 (which is only sensitive to these longer pulses). This energizes relay 8 thereby shifting contacts 10, 11. Thus relay 9 is deenergized and so the projection lamp 20 is extinguished and the transport mechanism is powered by a pulse through terminal 13. This causes the magazine 17 to be stepped in a reverse direction until it reaches the predetermined position when the switch 18 is opened by a follower thereon entering a recess 26 on the magazine 17.

[Also in Division F2]  An escapement device for actuating the printing wheels and card shift mechanism of a time recording device comprises a catch 10 engageable with a rotary bar 11 having two pairs of abutments A, B, C, D and A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, D<SP>1</SP> at each end whereby certain pulses applied to a device for moving the catch permit movement of the bar through a small angle whereas alternate pulses permit an end-for-end movement of the bar. The catch 10 is mounted on an arm 9 pivoted on a lever 5 by a bush 4, one end of the lever being attached to a spring 8 and the other end being attached to an armature 2 of a solenoid 1. The solenoid is energized at half-minute intervals by pulses from a master clock so that the catch 10 is lifted away from the abutment B due to the rotation of the lever 5 and the arm 9 about a pivot 6. A clockwork driven shaft 13 therefore rotates the bar 11 until the abutment C engages the catch. On de-energization of the solenoid the catch moves back to its initial position, the bar 11 effecting a further rotation until the catch engages the abutment D. At the next pulse the movement of the catch enables the bar 11 to rotate by 180 degrees until the catch engages the abutment B<SP>1</SP>. The first pulse only allows a small movement of the bar 11, this movement being too small to cause displacement of the printing wheels or card shifting mechanism of the time recorder so that the time is printed at one-minute intervals only.
