Patent DE-4414193-A1 (DE)
Inventor: STEFFAN HERMANN DR
IPC: B60R22/46
Filed: 1994-04-22
Abstract: The seat belt reel has a tensioning spring (29) and a geared hub (21) which is located inside the servo drive. This has an inner geared chamber (19) and a floating planetary gear wheel (28) between the hub and the chamber. The hub also has a radial wall (20) which forms one side of the pressure chamber with the planetary wheel the other side of the pressure chamber. The safety release control (14) activates the pyrolytic charge (17) to feed gas between he radial wall and the planetary wheel and thereby drive the seat belt spindle to tension the belt. The gearing of the planetary wheel and the hub is selected so that the planetary wheel follows the radial wall at approx. half the radial speed of the wall. This allows the wall to describe nearly two revolutions before stopping behind the planetary wheel. This provides a controlled tension length for the seat belt. <IMAGE>

Patent DE-4415852-A1 (DE)
Title: Holder, housing, receptacle imperviousness testing method
Inventor: SCHROFF GERHART
IPC: G01M3/22
Filed: 1994-05-05
Abstract: The method involves using a test-chamber (5), a pressure sensor (8) and a gasiform test fluid (9,10). The object to be treated is placed in the test-chamber under raised pressure monitored by the pressure sensor. It is then bombarded with the gasiform test fluid. A radiation source (1) emits an electromagnetic or laser beam (2) which enters through a window (4), passes through the object and then through a further window (6) to an analyser (7).The frequency-stabilised beam detects the pressure fluctuation caused by the leaking of the test fluid. A resonance frequency analyser in the test chamber may be used to pick up the modulation of the incoming electromagnetic beam caused by the pressure-fluctuation created by the emission of the test fluid. This can be converted to an acoustic signal.
Patent DE-4417286-A1 (DE)
Title: ATM buffer circuit data read-out method
Inventor: BARTEL WILLY
IPC: H04J3/06
Filed: 1994-05-13
Abstract: The method involves the buffer level being evaluated from the half-full indicators (H). It uses the buffer level indication to control the introduction of empty filler  data bytes between used byte blocks. The half-full indicator (H) for memory blocks 1 to n are acquired and evaluated. Further indicators for at least one cell filled, one quarter of cells and three quarters of cells filled are also used. According to the memory block 1 to n, a different number of empty bytes are assigned, where the number of empty bytes introduced between used blocks varies. The read-out from blocks with low data levels is at a low rate, while the read out from block with high data levels is at a high rate.

Title: Method for cleaning water by freeze crystallisation
Inventor: KOTTHOFF CARL-LUDWIG DR
IPC: C02F1/56
Filed: 1994-07-18
Abstract: Method for continuously cleaning lightly polluted water where the water from a storage tank (1) is cooled in a heat exchanger (4) and enters a recirculation loop (5, 6, 8) with a cooler (5) where it is seeded with small ice crystals, and an insulated tank (6) where the ice crystals grow. At the tank (6), ice crystals are filtered out (62), washed and filtered (10), thawed (4) and discharged (15) as cleaned water.

Novelty is that the drawn-off concentrate (21) is dosed with a coagulant (24) and enriched with solids (25) before being collected for disposal (27).
Patent DE-4426337-A1 (DE)
Title: Wheel suspension for skateboard
Inventor: MUELLER RUDI
IPC: A63C17/18
Filed: 1994-07-25
Abstract: The invention relates to a skateboard which is controlled via the feet by shifting of weight. In order that the wheels, for sporting purposes, should have a high lateral guidance capability and a consistently good surface contact (thus also permitting use on uneven surfaces), they are suspended individually and sprung relative to the board structure. The wheel suspension function is provided by a twist-beam axle which, in straight-ahead travel, exhibits the properties of a trailing link axle (constant king-pin and tow-in angles). In cornering, the effect of a kinematic connection of the two links of an axle is that all wheels adopt a steering angle towards that side to which the driver's weight is shifted, with no significant change in the king-pin angle relative to the board structure. This joint inclination of the wheels when cornering is an essential precondition for the transmission of high transverse acceleration and for a handling performance which is typical of sliding sports. The kinematic properties of the tie-beam axle can be further enhanced or supplemented by a variety of elastokinematic means. <IMAGE>

Title: Rotary driving unit for a belt tensioner
Inventor: ERNST HANS-HELLMUT
IPC: B60R22/46
Filed: 1987-01-31
Abstract: Rotary driving unit for a belt tensioner in a safety belt system. The belt is inserted over a driving reel (1) with a gripping surface (2) which is rotatively pressed against the belt (3) when the system is activated. When the length of belt to be inserted equals 180 mm, the outer diameter of a single-stage rotary piston cylinder used as driving reel equals 70 mm, or if a double-stage rotary piston cylinder is used, a diameter of only 40 mm is required. An alternative drive of the driving reel consists of a cable driven by a pyrotechnic linear cylinder. This kind of belt tensioning does not interfere with the mechanism of the retractors, works independently from the retractors, is easily combined with a belt clamp which works only in case of an accident, is very compact and economic, thanks to its simple mechanical design comprising few parts only. In a very economic construction with only a few additional parts the belt tensioner can also be used after being activated as belt retainer, so that the same element, after tensioning the belt, also takes up the load resulting from an accident.
