Title: Cine projector with switching roller - with film brake inoperative in direction of film advance
Inventor: LEISRING HERBERT DIPL ING
IPC: G03B1/24
Filed: 1975-09-20
Abstract: Cine projector comprises a switching roller (10) which is disposed behind the film guide in the film gate region, for return of the film over the roller. In the path of the film is a brake (107, 114) which when the film is returning holds the film section between itself and the switching roller. The brake is inoperative in the direction of advance of the film, and may include a free-running coupling (107, 108). Pref. the brake is in the form of a braking roller (101) of which the braking member (114) presses against an annular intermediate member (107). The latter is retained by a stationary component via a lock (107, 108) when the braking roller is turning in the direction of return of the film, and released via the same lock for engagement by the braking member when the braking roller is turning in the direction of advance of the film.

Title: Silent pile driver with reaction support - has holding chains and transverse member for pusher reaction forces
Inventor: DUMONT FRITZ
IPC: E02D7/20
Filed: 1975-08-30
Abstract: The pile driver has transverse member with arrangement exerting high pressure force on the pile for driving purposes. Reaction forces are transmitted by tension members such as chains to adjacent piles in the sheet piling wall. This arrangement is used mainly for correcting the sheet piling driven previously by other means. The sheet piling members projecting several metres above other members are readily driven without noise, vibrations and shocks. The chains (3, 4) are longer than the stroke of the piledriver. The end parts of chains are held by the yokes (11) on the previously driven piles. The end of a chain is pushed through a gap in the yoke and firmly held. The length of a chain is regulated by the yoke and the fastener.

Title: Label transfer from magazine by vacuum cylinder - is controlled by solenoid operated friction lever
Inventor: KOPPLIN MANFRED
IPC: B65C9/14
Filed: 1976-09-29
Abstract: A label transfer cylinder (3) which has intermediate rotation, is placed above a label stack. The cylinder (3) has a suction slot (4) so that due to the vacuum, the top label of the stack is picked up. The label is then transferred to the labeling roller. A hinged lever (11) with a rubber pad (12) rests on the top label without preventing its removal by the transfer cylinder during normal operation. If a sensor signals that no label is required, an electro magnet pulls the lever (11) onto the label stack. The vacuum in the transfer cylinder is thus not strong enough to overcome the increased friction on the top label.
Patent DE-2650199-A1 (DE)

Title: Automatic adjustable strut for furniture - has spring loaded catch on outer tube engaging threaded inner bar
Inventor: HAUSCHOPP NORBERT
IPC: E05C17/30
Filed: 1976-11-30
Abstract: The strut has a threaded inner bar (2) sliding inside an outer tube. Locking in compression is attained by a toothed catch (8) pressed against the inner bar (2) by the transverse component of the pressure of the inclined edge (7) on the catch (8). The latch is lightly spring-loaded against the inner bar. A sliding component (15) between the inner bar (2) and the outer tube separates the catch from the inner bar when the strut is fully extended. The strut can be fully closed so that the inclined surface (17) pushes the slide (15) upwards, re-engaging the catch (8). The strut may now be extended to the required length.

Title: Sintered carbide thread cutting die - is moulded around gap forming rods and electroeroded subsequently
Inventor: ROSSETTI HUBERT
IPC: B23P15/48
Filed: 1976-12-15
Abstract: The thread cutting die blank is produced by pressing a metal carbide powder into a mould which is roughly of the shape of the thread cutter.

Patent DE-2720314-A1 (DE)
Inventor: NESTLER WOLFGANG DR ING
IPC: H02M1/08
Filed: 1977-05-06
Abstract: The inductive load (18) is connected to the AC network on the one hand directly and on the other hand via a triac (24). A series circuit which comprises a resistor (4), a varistor (6) and a further resistor (5) is connected in parallel with the triac (24) and is supplied via a first diode (2). The anode of the first diode is connected to one connection of the load, and the cathode of the first diode is connected to one end of the series circuit. A capacitor (7) is charged by the positive half-cycle of the network voltage via the resistor (4) and another diode (11) to a voltage which is limited by the first-mentioned varistor (6). The discharging of the capacitor starts via a further diode (10) when the voltage falls below the aforementioned limited voltage. In this case, a negative pulse is emitted to the control electrode of the triac, via a further varistor (25), in order to trigger the triac (24). In this way, triggering pulses are emitted to the triac in the last part of each positive half-cycle such that the power supplied to the load is only very slightly dependent on the operating voltage and ageing of the components. <IMAGE>

Title: Fault-free laying out of material patterns - using comparison table with original image and television camera
Inventor: HERRMANN FALK
IPC: A41H3/00
Filed: 1977-07-14
Abstract: The fault-finding processing for avoiding faults in material when cutting out pattern pieces is undertaken when laying out layers of material by comparing the relevant layer with the original cutting image on a scale of 1:1. In the event of a fault it can be detected whether this occurs in the material waste area so that it can be disregarded or whether it can be brought into the position by turning, rotating or displacing the relevant layer. This comparison is achieved using a comparison table which is mounted parallel to the cutting out table and contains an original pattern image with true co-ordinates. The comparison table also supports a measuring carriage which is rigidly coupled to the laying-out carriage, and is provided with a transversely displaceable television camera which stores the measured values.
