Abstract: 1296580 Copying cameras PENTAGON DRESDEN KAMERA-UND KINOWERKE VEB 24 Oct 1970 50611/70 Heading G2A A copying camera has a diaphragm which can be moved across the image aperture so as to provide different formats, the movement being coupled to means for also moving the taking lens so that its optical axis remains central to the image aperture. The arrangement described provides for three different formats A2, A3 and A4. Two lenses 2, 3 are mounted in a carrier disc 1 rotatably pivoted at its centre. The disc can be pivoted through an angle α by means of a bar 4 coupling it to a motor-driven wheel 5. The film 15 traverses across an aperture 14 in a gate 21, and the aperture can be partially covered by a diaphragm 8 which is formed as one arm of a spring-loaded lever pivoted on a pin 16, and whose movement can be controlled by a pin 9 on disc 1 which engages with a cam surface 18 of the lever. The particular format required is chosen by actuating the corresponding press button (23), Fig. 3 (not shown), the movement of the disc 1 then being controlled by the circuit of Fig. 3 (not shown). Figs.1 and 2 show the position for format A4. The aperture 14 is half-covered by the diaphragm 8, and the lens 2 has been moved from position 2 to position 2, Fig.2, so that its optical axis still passes through the centre of the remaining open half of aperture 14. A switch arm 6 extending from disc 1 closes the switch contacts a, b in the A4 section of the Fig.3 circuit. For format A3 the disc 1 is rotated slightly clockwise. Diaphragm 8 moves so as to leave the whole of aperture 14 open, and lens 2 moves into the dotted line position 2 in Fig.2. For format A2, disc 1 is rotated through the whole angle α. The aperture 14 is again fully open, and lens 3 is moved into alignment with it.

Abstract: 1296946 Fluid logic and switching circuits; regulating engines KNORR-BREMSE GmbH 19 April 1971 [5 March 1970] 23356/71 Headings F1B and F1P] A fluid logic switching circuit for timing of fuel supply to injectors 6 Fig.1 of an I. C. engine 1 comprises a comparator 100 Fig. 6a having an input 107 for receiving a pressure signal that is an analogue of momentary fuel requirements of the engine 1, a second input 106 to which is fed a comparison signal pressure and an output 108 by which a switching signal is delivered when  comparison pressure signal at 106 exceeds the analogue pressure signal at 107, the switching signal being fed to a first control input 109 of a bistable element 102 having a second control input 110 fed with a digital pressure signal having a pulse frequency dependent on engine speed, one output 103 of element 102 providing a digital injection control signal in a line 99 and also being supplied to input 106 of comparator 100 through delay means 104, 105 whereby switching of the output of element 102 from a vent 111 to output 103 initiates build-up of the signal at 106 and consequential triggering of comparator output at 108 which in turn terminates the injection control signal in line 99 until a further engine frequency pulse arrives at 110. The digital pressure signal for input 110 is derived from an engine-driven pulse generator 16 having outlets 22...25, connected to form inputs of an OR element 42 having an  output line 48 from which branches a line 48' leading to what 110 of element 102. The analogue pressure signal for input 107 is in part derived from the output line 48 of OR element 102 and which is fed to digital-analogue converter 15 the output of which is amplified at 81 and fed to an analogue computer 84. The remainder of the analogue pressure signal for input 107 is derived from a manifold pressure indicator 14 which provides a constant pressure in a line 16 and after amplification at 80 is fed to 84 and the output of the latter provides said signal at 107. The converter 15 comprises a bistable member 49 Fig.3 having control inputs 55, 57 connected to the output line 48 of OR element 42 by flow paths 53, 51 of differing flow resistances whereby digital pulses are generated at an output 59 and which are an analogue of engine speed. These signals are amplified at 81 before passing to computer 84. The injection controls signals in line 99 form an input to AND elements 95...99 each of which has a second input connected to output lines 22...25 of pulse generator 16 driven by the engine and the outputs of elements 95...99 are connected by lines 26...29 to injectors 6 which are thus timed. Instead of feeding manifold pressure signals along line 18 to amplifier 80 pulses dependent on the setting of the air inlet valve 5 and generated at 13 may be fed along a line 17 to said amplifier.

With the probes coupled via their scanning and receiver circuits to an oscilloscope, shaft 39 and the pre-settable gain control circuit for the probe engaged by tool 30 are adjusted for maximum and equal pulse echo responses from the reference internal and external flaws, ring 16 being moved axially by a piston and cylinder 37 to bring the probe over the reference flaws in turn. Ring 16 is then indexed to bring a second probe into engagement with tool 30, the previously-adjusted position of the tool providing a coarse adjustment of the second probe's orientation. Fine adjustment, plus the gain adjustment, are then made for the second probe. When all probes on ring 16 have been adjusted the ring is transferred, with its connected circuits, to the Fig. 2 apparatus.
