Title: Holder for camera
IPC: H01M2/10
Filed: 1973-09-21
Abstract: 1412506 Gyroscopic camera support K MITO 21 Sept 1973 [11 Oct 1972] 44450/73 Heading G2A A camera is detachably mounted on a base which includes a pair of gyroscopes and drive means therefor, the base having two handles, of which one has means for actuating the camera shutter release after the drive means has been operated, thus stabilizing the camera during the actual exposure. As shown, the camera 13 is attached by a screw mounting 5 to a mounting base 2 having a lower casing 11 containing the gyroscopes. On either side of base 2 are handles 7, 10 handle 10 containing batteries 16, 16' for driving the gyroscopes. As shown, two gyroscopes 22a, 22b, with mutually perpendicular shafts, are mounted in movable gimbals 25a, 25b, themselves supported in fixed gimbals 21a, 21b. To handle 7 is fixed one end of a flexible shaft 15 whose other end is attached to the shutter release. Within handle 7 is an operating lever 19 pivoted at one end on a shaft 20, and biased by a spring 40 so that a button 8 extends through an opening to the exterior. When button 8 is pressed, a first projection 19a on lever 19 engages against a transmission lever 39, which causes brake shoes 29a, 29b to be disengaged from gyroscopes 22a, 22b, so leaving them free to rotate. A second projection 19b then closes a switch 44, which completes the circuits to the motors 23a, 23b which then drive the gyroscopes. A third projection 19c then engages the release wire 43 running through shaft 15 to actuate the camera shutter. When button 8 is released, the motor circuits are broken, and the brake shoes 29a, 29b are spring-urged back into contact with the gyroscopes to bring them to a stop. In another embodiment Figs. 7 and 8 (not shown), the braking is effected electrically.

Title: Corpuscular beam apparatus
IPC: H01J37/141
Filed: 1972-09-28
Abstract: 1406862 Automatic control of radiation SIEMENS AG 28 Sept 1972 [28 Sept 1971]  44758/72 Heading G3N The current in a lens of corpuscular beam apparatus e.g. an electron microscope is controlled by the analogue voltage from a digital to analogue converter having the reading of a digital forwards/ backwards counter as input. The counter reading is set from a manually controlled pulse generator via logic circuitry and the counter may be set automatically to a series of values around a desired mean for focusing tests by using a backwards counter and a shift register. As described, forwards/backwards counter 7 has forward input 13 and backward input 12 and its outputs 8 are connected to Digital to analogue converter 9. The counter 7 is set to an initial reading (say 7) by pulses from manually controlled generator 15. If it is desired to take exposures of four slips each side of this value (i.e. from 3 to 11), the value 4 is set by switch 35 into backwards counter 16. The sequence is controlled by shift register 14. In operation, shift register 14 is initially in position SR and pulse generator 15 is operated to set the value 7 in counter 7 and switch 35 to set the value 4 in counter 16. A start signal at 18 steps register 14 to output S 1  and pulses from clock 17 counts counter 16 down to zero when a pulse at 20 steps the register to output S 2  and also counts counter 7 down to 3. Counter 16 is reset to 4 and photos are taken at counts of 3, 4, 5, 6 and 7 using pulses from device 34 to step counter 7 up and counter 16 down. At the reading 7 counter 16 reads zero and steps register 14 to S 3  and is itself reset to 4. The process is repeated for exposures at 8, 9, 10 and 11 and the shift register is then set to S 4  and counter 16 to 4. Clockpulses from 17 then count: both counters down; 7 to its original reading of 7 and 16 to zero when register 14 is switched to its initial position S R . The size of the steps can be varied by input 11 to counter 7.
