Title: Strip holder for detonator fired flash bulbs - has protective shield around each detonator to accurately locate striker
Inventor: HENNIG FRIDOLIN
IPC: G03B15/04
Filed: 1973-12-10
Abstract: The inertially fired flash bulbs are held in a special strip which has a plastic reflector pressed into a series of reflecting surfaces. The bottom ends of the strip are fitted with protective shields on each side of the detonator tube fitted to each bulb. The detonator tubes are inserted through holes in the bottom of the strip and can be protected further by thin strip material over the tubes. The striker is accurately aimed at the tubes in turn, by the protective side plates and is strong enough to penetrate the thin protective strip over the tubes. The system ensures that when a bulb is fired any distortion in the bulbs and strip does not inhibit the firing process of the next bulb by mislocating the striker.

Title: Mechanism for detection of photographic film fractures - counts and registers these faults using infrared detection system
Inventor: WEBER KLAUS DIPL ING
IPC: G01N25/72
Filed: 1974-09-24
Abstract: The film is wound from a spool (1) through pinch rollers (2) over a conical roller, and through the checking stations, which consist of infrared sources and photodetectors arranged to detect any fractures in the areas mentioned. The film is then wound on to another spool (12) after passing between two further pinch rollers (11). In particular that checking the sprocket hole arms uses a system of feelers attached to lever areas. Any fault triggers a Schmitt trigger circuit via a Darlington amplifier and the photocell detector. The Schmitt trigger in turn operates a monostable flip flop and counter, which thus holds a record of the fractures detected in a particular piece of film.
Patent DE-2453566-A1 (DE)
Title: Inner paper filter bag for carpet sweeper or vacuum cleaner - has reinforcement plate with extra retaining means releasing strain on dirt sealing openings
Inventor: STETTNER GERHARD ING GRAD
IPC: A47L9/14
Filed: 1974-11-12
Abstract: The carpet sweeper or vacuum cleaner (2) is provided with an outer dust bag (4) enclosing a paper filter bag (8) which has a reinforcement plate (9) and opening (10) which fits sealingly onto the end of the dust pipe (11) and acts as the connecting pipe (6) which on the section on which the plate (9) is adapted to move has the same or conically increasing external dimensions. Retaining devices with which the reinforcement plate (9) can be brought into positive or non-positive engagement are mounted more or less diametrically opposite on the connector pipe (6). Since the opening (10) in the reinforcement plate (9) no longer acts as a retaining or supporting means it does not have to be pressed over an annular flange and the peripheral zone need therefore only be of relatively slight resilience to provide the necessary sealing function.

Abstract: The basic transducer is a photoresistor (27) which is subjected to a series of light pulses from a slotted disc attached to the shaft concerned, so that typically 100 pulses of light per revolution are detected. These pulses are amplified and shaped by transistor circuitry (6) and applied to an AND gate (7) to the other inputs of which are fed waveforms derived via frequency dividers (2) from a quartz oscillator (1). The various pulses are processed by an arithmetic unit and the result displayed digitally. The frequency dividing unit may be set up to suit a particular wheel diameter for speedometer applications, while zeroing and resetting facilities are provided by two switches (8, 10). The link between basic transducer and logic network is by cable (6a).
Patent DE-2507667-A1 (DE)
Title: Foundation construction for areas at water table - uses friction floor plates and wall to compensate for buoyancy
IPC: E02D29/045
Filed: 1975-02-22
Abstract: The foundation are esp. for open construction traffic tunnels, and are constructed without or only slight lowering of the water table. The foundations consist of walls, retained at the top and the bottom, and an intermediate concrete base. The resulting buoyancy forces acting onto the base after the construction has been pumped free of water, are compensated for only by friction action in the joint between wall and base. The friction is produced by bearing forces of soil- and water pressure at the lower support points of the wall, on the level of the bed. The static system of the walls for the construction, relative to the water-filled construction, is altered so that the bearing force at the lower support of the wall on the level of the bed is as high as possible.
Patent DE-2508254-A1 (DE)
Title: Automatic brake for articulated trailer - has brake control sensor under supports operating when they are dropped
Inventor: WEBER PETER
IPC: B60T15/02
Filed: 1975-02-26
Abstract: The support legs for the articulated trailer are fitted with sensors (11) on the underside, between the support wheels (8). The sensors apply the brakes when the supports are dropped to the ground. The system enables the trailers to be moved about a goods yard without lifting the legs, and without complete coupling of the trailers to the towing units. The towing units merely engage and lift the trailers and move them in the lifted position. When the trailers are dropped the brakes engage automatically to secure the trailer and prevent it from running away. The trailers can thus be moved rapidly and with single handed effort.
