Patent GB-1357622-A (GB)
Title: Photographic camera
IPC: G03B17/42
Filed: 1971-12-09
Abstract: 1357622 Film transport BALDA-WERKE PHOTOGRAPHISCHE GERATE und KUNSTSTOFF R GRUTER K G 9 Dec 1971 [21 Jan 1971] 57249/71 Heading G2A A roll film camera for film having one perforation per image frame has a feeler member for engaging this perforation and locking the film feed accordingly, with a spring-loaded shutteroperating lever mounted on a displaceable release element, the lever being moved out of engagement with the feeler member during film winding by lugs on the winding wheel. As shown, a wheel 2, which rotates when the film transport is operated, has a number of lugs or cams 2b, 2c, etc. extending from its underside. A lever 10, pivoted at 8 on a release slide 4, has a nose 10a in the path of movement of the cams. In the rest position Fig. 1, (not shown) lever 10 and slide 4 are at rest under the action of their respective springs 9 and 6. The feeler member 11 has an angled end 11a which is engaged behind a bevel surface 10c of lever 10, so that feeler 11 is held, against the action of its spring 12, out of contact with the film strip 13. Wheel 2 is now rotated clockwise to wind on the film, and in doing so one of the lugs (2b as shown) engages the nose 10a of lever 10 and pivots the lever anti-clockwise until it comes up against a stop 3 (position of Fig. 2). The feeler member 11 is now freed to move so that its feeler and 11b can abut against the film 13, and when it registers with a perforation 13a it enters therein as shown in Fig. 5. This movement is at the same time arranged to lock the film transport. The release slide 4 is now pressed downwards to effect the exposure. As slide 4 moves down, the lever 10 is also drawn downwards, the nose 10a eventually being drawn clear of lug 2b. Lever 10 is then rapidly pulled clockwise into its rest position by spring 9. The bevel surface 10c engages behind end 11a and draws the feeler member back, against its spring 12, out of engagement with perforation 13a. At the same time an impact nose 10e of lever 10 strikes an impact surface 14a of the shutter blade 14. This blade, which pivots on a pin 15, is normally in the rest position shown in Fig. 2, in which it is drawn by a spring 16 to abut against a stop 18, its farther end 14b covering the exposure aperture 17. As nose 10c strikes surface 14a, the impact momentarily causes blade 14 to be pivoted anti-clockwise, against its spring, so uncovering the exposure aperture.

Abstract: 1368786 Making wire; machine frames; rolling; bar peeling TH KIESERLING & ALBRECHT 10 Dec. 1971 [27 April 1971] 57555/71 Headings B3A, B3B, B3M and B3T The machining of a workpiece is initiated by feeding the leading end 51a of the workpiece through open calibrating and straightening rolls 16, 17 and feed and delivery rolls 5, 6 of a machining device 4, adjusting the rolls 16, 17 to produce a slight reduction of the workpiece and thereafter adjusting the rolls 16, 17 to produce the desired reduction when the leading end 51a of the workpiece is engaged by a device 7 which draws the workpiece through the rolls 16, 17 and machining device 4 at the required speed. The leading end 51a of a wire coil 51 is first fed by a driven roller 8 through a cutter 2 for cutting off an unwanted end of the wire and through axially displaceable calibrating and straightening roll stands 16, 17, each comprising three freely rotatable rolls (20) (Fig. 3, not shown) offset at an angle of 60 degrees relative to the rolls of the other stand. The feeding of the wire is taken over by the feed rolls 5 when the wire end 51a reaches the feed 5 and delivery rolls 6 of a turning device 4, at least the feed rolls 5 being driven by a worm (39) (Fig. 4, not shown) via a shaft (37), overrunning clutch (36), gears (32b, 31b) and drive shafts (31a, 32a). The calibrating and straightening rolls (20) are moved inwards by an amount preselected on a pulse storing device 44 so as to produce a slight reduction of the wire by depressing a key (46a) (Fig. 6, not shown) of the device 44 to start a motor 29 which axially moves a sleeve (26) to which the rolls (20) are connected by pivoted levers (24). The wire is fed by the rolls 5 through the turning device 4 and to a reel 7, whereupon the rolls (20) are moved further inwards to their final operating position and the drive of the feed rolls 5 is stopped. The wire is then drawn through the apparatus by the reel 7 at a higher speed, the rolls 5 freely rotating and the clutch (36) being caused to overrun. The rolls (20) are prevented from being opened beyond a fixed position by a limit switch (50).

Patent GB-2036390-A (GB)
Title: Improvements in or Relating to Telephone Exchanges
IPC: G06F7/74
Filed: 1978-12-07
Abstract: Each fault in a data processing system, such as a centrally-controlled in telephone exchange, sets a 1 bit into a shift register 1 at a position appropriate to the faulty device's identity. When the central processor needs a fault report it causes a control circuit 2 to freeze the shift register and drive the data therein along the register until the first fault representing 1 bit reaches a predetermined point, eg the rightmost stage. The drive pulses also drive a counter 3 which is also stopped when the register is stopped. Thus the counter is set to a state representing the faulty circuit's identity, and this counter state is sent to the processor. Operations are then re-started to read out the identities of other faulty circuits. <IMAGE>

Patent GB-2036899-A (GB)
Title: Improvements in Spreading Disc Brakes for Vehicles
IPC: F16D65/22
Filed: 1979-10-24
Abstract: In a disc brake of the spreading type an automatic adjuster 20 is located within the housing 1 of the brake. The adjuster 20 comprises an extensible strut 21 which acts between radial lugs 16, 18 on pressure plates 6, 7 to maintain the pressure plates 6, 7 in relative angular positions in which the braking clearances are maintained within predetermined limits. In the construction described the strut 21 is coupled at each end to a respective plate 6, 7 through a lever 24, 25 which is urged into a neutral position by a spring 34. The load in the spring 34 is chosen to permit the lever 24, 25 to move angularly about a pivotal connection 26, 27 with its respective plate 6, 7 and prevent the effective length of the strut 21 from being increased further as a result of loads which are transmitted through the strut 21 as a consequence of structural deflection of the housing 1. The adjuster is therefore said to be "load-insensitive" for both directions of disc rotation. <IMAGE>
