Filed: 1974-04-29
Abstract: 1436972 Cameras FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 29 April 1974 [14 July 1973] 18678/74 Heading G2A A camera has a diaphragm drive ring 17 which runs down to a position determined by the position of a control cam 14 on a pre-setting ring 13; ring 13 being positioned by an electromagnetic drive 2, 4 controlled by a bridge circuit Fig. 2 (not shown) which includes a photo-electric element (28) and a balancing resistor (26) whose value is varied upon movement of the electromagnetic drive. As shown, a coil 4 moves into a magnet 2 until the resistor (26) coupled to the coil balances the bridge. Preferably the bridge includes film and shutter speed setting resistors (29, 30). This movement of the coil 4 moves the pre-setting ring 13 anti-clockwise via a lever 11. A pointer 15 indicates the pre-set diaphragm value. On shutter release, a shutter ring 24 runs down so releasing a locking pawl 21. This allows blade ring 17 to be rotated anti-clockwise by a spring 38 to close down the aperture. Movement of ring 17 also pivots a lever 20 clockwise and when lever 20 abuts the control cam 14 movement of ring 17 is arrested. After shutter closure a switch (36) is closed to move the coil 4 further into magnet 2 whereby ring 13 rotates further anti-clockwise to re-set lever 20 and ring 17. For manual setting, a ring 34 is adjusted to the required value. This also closes a switch (33) to move ring 13 until pointer 15 is arrested by a stop 35 on ring 34. The invention enables view-finding and exposure control to be carried out in SLR cameras with a fully open aperture.

Liquid-meters.-Apparatus for delivering measured quantities of liquid comprises two receptacles movable about an axis of oscillation so that when one of the receptacles is filled the excess liquid which continues to flow in is diverted to the other receptacle in such a manner as to produce the oscillation and emptying of the first receptacle, the other receptacle being ultimately and in its turn completely filled. As shown, two receptacles 1, 2, Fig. 1, are mounted on trunnions 3 so as to oscillate as a single unit. Within the receptacles are two channels 4, 5 divided by a common wall 6 and leading into opposite receptacles. The liquid is fed to the receptacles through a pipe 7 and, in the position shown in Fig. 1, runs into the receptacle 1 until the level of the liquid reaches the top of the wall 6 when the excess liquid flows over into the second receptacle 2 as shown in Fig. 2. The excess liquid runs into an eccentric portion 9 of the receptacle 2 until by its increasing weight it causes the two receptacles to rock upon the trunnions 3 into the position shown in Fig. 4, the movement being limited by a stop. A siphon 8 now discharges the filled receptacle 1 and a similar operation takes place in connection with the receptacle 2. When used as a meter a counter 10 adds up the oscillations of the receptacles.

Abstract: 220,952. Pantoflicek, B. Aug. 20, 1923, [Convention date]. Dropping bombs from a height.-Several small bombs are enclosed in a two-part casing, which is hinged along the bottom and opens out, after discharge from an aircraft thereby scattering the small bombs. As shown in Figs. 1 and 3, the casing 1 comprises two sides 4, 5 interlocked by tongues and slots 10, 11 at the bottom, and held closed at the top by a slotted bolt 22 embracing lugs 20 on the sides 4, 5 and by the members 16. 17 of the dropping gear embracing the head 15 constituted by two separate halves secured to the sides 4, 5 respectively. When the casing is held by the dropping gear 16, 17 it bears against a stop nut 23 on the bolt 22 and also against another stop 25. Before, use, the casing is held closed by ties 40 provided with seals 44, one such tie being also used to fasten the two halves of the head 15. The seals are broken and the ties removed when the casing is hooked to the dropping gear. The casing may contain bombs of different sizes x, x<1>; the smaller bombs may be separated by partitions 32; springs 35 may be provided to open out the casing when it is dropped; and the sides of the casing may be provided with protective, armour plating. The small bombs may also be scattered by an explosive charge; and the scattering may take place immediately the casing is dropped, or during flight, or before or on impact, with the ground. The Specification as open to inspection under Sect. 91 (3) (a) also describes two modifications. In one, Fig. 6, (Cancelled), small bombs x are inserted in a tubular casing 50 closed by a lid 52 fastened by a lever catch 55, 58, which is secured before use by a tie 70 and seal 71, and, after the tubular casing has been hooked to a dropping gear 16, 17, by engagement with the said dropping gear. When the tubular casing 50 is dropped, the lever 55 is released, and, in swinging out, releases the lid 52, whereupon a piston 63 under the influence of a spring 64 drives the small bombs out of the tubular casing 50. In the other modification, the tubular casing 50 is dropped from a vertical launching tube, which confines the lever 55 until the tubular casing 50 drops cut of the launching tube. This subject-matter does not appear in the Specification as accepted.
