Title: Cinematic equipment shutter selector aperture mechanism
IPC: G03B1/42
Filed: 1974-01-23
Abstract: 1407191 Cine projectors BENCINI SpA 23 Jan 1974 [9 Feb 1973] 03116/74 Heading G2E  A cine projector which can accept film spools of two different hub sizes corresponding to different film frame sizes has a mask with two openings therein defining the respective shutter apertures, such that a spool can be accepted only when the appropriate aperture opening is aligned with the optical axis. The two frame sizes in the particular embodiment described are Single (Super) 8 and Double 8. The mask is a plate 18, seen in Fig. 4 in the position for projecting Double 8 film, with opening 30 aligned with the optical axis. By displacing plate 18 laterally, the other opening 20, for projecting Super 8 film, is brought into the axis, position of Fig. 3 (not shown). Plate 18 is displaced by means of a vertically sliding plate 6, linked to plate 18 by a bell-crank 24. Plate 6 is biased upwards, into the "Super 8" position, by a spring 12. A catch 3 has two wing portions 63, 64 and an arcuate main portion 61, the catch being biased towards the projector wall 5 by a leaf-spring 2 which engages a finger 66 extending from the catch. In this "Super 8" position the spool hub (40), Fig.6 (not shown), can be received by the axle 31 and can rotate without its flange (41) contacting the arcuate portion 61 of catch 3. If projection of "Double 8" film is required, the hub has to be replaced by hub 50, and in this position the flange 51 of hub 50, which is bigger than the flange of the other hub, inter-engages with a finger portion 32 of slide plate 6, and is thus prevented from being properly received by axle 31. When finger 32 is pressed downwards, it no longer prevents the proper engagement of hub 50, and at the same time plate 6 is forced downwards into its lower position, which changes over the apertures in plate 18. The plate 6 is locked in this lower position, against the action of spring 12, by the catch 3. When hub 50 is replaced by the "Super 8" hub (40), its flange (41) disengages the catch 3, which allows plate 6 to be moved upwards again by spring 12.

Title: Improvements in or relating to the electrochemical machining of metals
Inventor: BENNETT ROBERT STANLEY
IPC: B23H7/18
Filed: 1963-01-25
Abstract: In electrochemically drilling holes in a workpiece, the gap voltage between the electrode and workpiece and the feed speed of either the tool electrode or the workpiece towards the other are varied simultaneously to maintain the ratio of the feed speed to the gap voltage substantially constant. By this means the gap lengths (i.e. the gap between the forward part of the electrode and the bottom of the drilled hole and between the side of the electrode and the sides of the drilled hole) remain constant and the diameter of a hole remains constant during machining. Fig. 1 shows a hollow electrode 16 fed towards a workpiece 17 by an electric motor 9 driving through a gear box and drive nut 10. Electrolyte is supplied through the hollow electrode 16 from a pipe 14. Mains A.C., applied to terminals 1, 2 and rectified at 4 and 7, provides both electrolysing current and current to a field winding 8 of the motor 9. By adjusting transformer 3, e.g. by a hand wheel, both the feed speed and gap voltage are adjusted. By adjusting switch 6, the desired gap width or radial clearance between the electrode and drilled hole can be obtained. During drilling, the switch is not disturbed but transformer 3 can be adjusted to alter the feed speed without affecting the size of the hole being drilled. Similarly, fluctuations in mains voltage do not affect the accuracy of the hole. Fig. 2 shows circuitry wherein a voltage V2 is derived which is proportional to the gap voltage. A fraction of this is connected to an amplifier 30 whose output feeds a servomotor 22. This servomotor drives the tool electrode 16 forward and also drives a tachogenerator 21 whose output voltage V3 is porportional to the tool electrode feed speed. V3 is connected to the input of the amplifier 30 and this servo loop maintains a balance between the tool feed speed and the voltage V2 thus maintaining the feed-speed gap-voltage ratio constant. Fig. 3 and 4 (not shown) illustrate electrolytically enlarging a hole and normal electrolytic drilling respectively. <PICT:1037662/C6-C7/1> <PICT:1037662/C6-C7/2>
