Title: Extendable belt deflector for three point safety belt - has lever drive with electromotor and self-locking gearing to extending pivoted lever
IPC: B60R22/20
Filed: 1991-12-06
Granted: 1993-02-25
Abstract: The belt guide swivel lever carries the reversal at its far end and is powered by a self-locking electric motor to move the reversal point out of a concealed side setting into an active setting in which the reversal point lies above the side clad top edge. The lever (21) is angled by a spring (44) which is pre-loaded into the concealed setting and drives the lever into its active setting. A coupling used to cancel the self-locking function can be disengaged by pulling the belt in the concealed setting and is automatically engaged by the lever (21) in the active setting. USE/ADVANTAGE - Three-point safety belts for motor vehicles without centre column. Belt locks by lever if power fails and remains locked until repaired, using self-locking lever drive.
Patent DE-4242807-C1 (DE)
Title: Synchronising signal generator to external clock signal - allowing signal generator to take on timing ratio of external clock signal.
Inventor: BICHLER HELMUT
IPC: H03L7/00
Filed: 1992-12-17
Granted: 1994-03-24
Abstract: The synchronising method involves first decoupling an external clock signal (TS). The resulting signal is then shifted by a predefined potential (Um). The shifted signal is fed as a trigger signal (TRS) to a signal generator (SG) and to a delay window discriminator (VFD). The latter applies a free-wheeling signal to the signal generator when the trigger signal is at the value of the potential which is in the window of the discriminator for at least a predetermined period. The signal generator then oscillates about its own frequency and is no longer synchronised from the trigger signal. ADVANTAGE - Simple construction. Can take on timing of sync. clock signal on loss of external clock signal or master system clock generator. Allows large tolerance margins for signal generator frequency.

Title: Rubber-metal support for vehicle leaf-spring suspension - has two half shells joined by flexible end bars
Inventor: BROKAMP SUSANNE
IPC: F16F1/38
Filed: 1993-03-24
Granted: 1994-06-01
Abstract: Rubber support for the central pivot of a leaf spring suspension in which the half shells (3, 4) of the rubber sleeve (1) are joined together at their ends by flexible bars (5). A gap is created allowing the shells to be fitted around the pivot (7). Recesses (12) are provided which accommodate the folded bars when subjected to radial compression. The bars are considerably shorter than the radial dimension of the groove-and-spring formation (8, 9) in the assembled state. ADVANTAGE - Allows the sleeve to be handled safely from production to fitting on the vehicle without impairing functionability.
Patent DE-4402442-C1 (DE)
Title: Process for improving wastewater clean up in trickling filter units
Inventor: BLASCHEK REIMUT DIPL ING
IPC: C02F3/26
Filed: 1994-01-27
Granted: 1995-02-02
Abstract: To improve the clean up efficiency in biological wastewater (effluent) clean up in trickling filter units, it is proposed to enrich the wastewater with technical-grade oxygen prior to entry into the trickling filter 13. Preferably, the technical-grade oxygen is incorporated into the wastewater via perforated gas-introduction tubes 5 in a prepurification vessel 4 upstream of the trickling filter 13. In this manner, toxic wastewater constituents, in particular hydrogen sulphide, can be oxidised even before entry of the wastewater into the trickling filter 13. Thus the risk of some of the biomass colonising the trickling filter 13 dying off because of the pollution of the wastewater with toxic substances is reliably averted. Moreover, odour pollution due to spraying fouled wastewater over the trickling filter packing material 15 by means of a spraying rake 14 is avoided. <IMAGE>

Title: Piano striker mechanism with double release
Inventor: BLOK SIMON ANTONIUS DE
IPC: G10C3/16
Filed: 1996-05-29
Granted: 1997-12-03
Abstract: A bottom hammer (2) is actuated by a key (1), and a bridge-piece (11) pivots on the hammer, while a top hammer (5) is actuated by an intermediate striker. An arrester is fixed to the bottom hammer. With a first release operation, one arm of the bridge spring works against a first fixed point when the bottom hammer is thrust upwards so as to be moved under the bridge-piece. With a second release operation, the bridge-piece only works with a striker (3), intermediate striker (4) and the top hammer after the first operation has taken place allowing the bridge-piece to drop. The striker is mounted on the bridge-piece, while the intermediate striker works between the bridge-piece and top hammer. The two strikers can hinge on the bridge-piece, the first one at a point between those of the intermediate striker and the bridge-piece itself. The distance between the bottom hammer and the bridge-piece hinge-point and between the bottom hammer and the intermediate-hammer hinge point may be the same.
