Patent DE-19612981-A1 (DE)
Title: Acoustic testing system for loudspeakers of stereo equipment
Inventor: WAGNER THOMAS
IPC: H04R29/00
Filed: 1996-04-01
Abstract: The testing system comprises a control unit (1,2,3) with a multi-sine signal (MS) generator (20) for activating the loudspeakers (L,R;10r,11r,12r;101,111,121), receiving devices with one or two microphones (M1,M2;4,5) for measurement and processing of the tone-signals given out by the speakers, and a comparator (1,2) for comparison of the toner-signals with previously indicated and stored signals. The microphones may be directed symmetrically (100,M) or unsymmetrically (RE,LI) at the loudspeakers. If the tone signals match the comparison signals sufficiently closely, the speakers are functioning to a satisfactory standard, and if not, they may be faulty or incorrectly assembled. Thus detection is acoustically automated.

Patent DE-19619985-A1 (DE)
Inventor: JONNER WOLF-DIETER
IPC: B60T8/24
Filed: 1996-05-17
Abstract: A known hydraulic vehicle brake system (DE 44 45 401 A1) has brake pressure modulation valve systems situated between a dual-circuit main brake cylinder and vehicle wheel brakes. Traction control is ensured by a pump device which is supplied from a reservoir of the main brake cylinder and forces hydraulic fluid into a first pressure chamber between a first piston and a second piston and feeds it to the brake pressure modulation devices connected to said first pressure chamber in order to lead at least a portion of it into the wheel brakes. The pressure in the first pressure chamber displaces the second piston, thereby ensuring that pressure is also applied to the other brake pressure modulation valve devices. The pump device is therefore a high-pressure pump. It is proposed that the pump device should take the form of a low-pressure pump (76), and a first and second return pump (40, 41) should be allocated to the brake pressure modulation valve devices (42, 43, 44, 45); in automatic brake operation, the first pressure chamber (17) should be connected to the first return pump, while the second pressure chamber (18) should be connected on the inlet side to the second return pump. The low-pressure pump (76) generates in automatic brake operation a load pressure for the return pumps (40, 41) significantly lower than a maximum brake pressure, and the return pumps (40, 41) generate the highest predetermined brake pressure and serve in any anti-lock operation to pump hydraulic fluid from the wheel brakes back to the main brake cylinder. Inside the proposed vehicle brake system, the inexpensive low-pressure pump (76) ensures a high level of efficiency of the return pumps (40, 41) in automatic brake operation.

Patent DE-19625395-A1 (DE)
Title: Vehicle airbag production
Inventor: MAERTZ JOSEF
IPC: B23K26/08
Filed: 1996-06-25
Abstract: To produce finished vehicle airbags for delivery, for steering wheel fitting, two layers of woven piece goods (1,7) of the same width are overlaid in the same direction, where the upper layer is the filter fabric and the lower layer the airbag material layer. Protective material (3) is applied to the upper layer, displaced from each other laterally and longitudinally, and holes (13) are cut through the protective (3) and upper layer (1) materials for subsequent connection to a gas generator.  The tightly packed layers are fed to a cutting table (15), where circular sections (5) are cut out by a laser cutter, and the edges of the overlaid circles are loosely brought together to form the airbag body, and are carried by a suction and conveyor system to a turntable, to pass them through a sewing station where the edges are stitched together. The airbag quality is controlled, and then they are passed to a folder for packaging into the required shape for insertion into a steer ing wheel. Also claimed is a folder with two grip clamps for the first folding stage, where they grip the outer sides of the flat airbag body at a gap for the dia. of the airbag. The grips are fitted to a shaft to give the first folding movement, to give them their rotation and counter movements. Further flat clamps, across the first grip clamps, give the second folding movement by grasping the ends after the first fold, with a gap between them matching the length of the airbag after the first fold. The grips are each on a shaft to give the rotation and counter movements to form the second fold of the package. Preferably all the prodn. stages take the same time, up to folding, and the stages are then in steps. An adhesive is applied locally to the upper fabric, to bond the protective section (3) of flame protection material under pressure. The protective sections (3) are stitched into place. The filter layer (1) is passed over a table (11), where a hole (13) is stamped through each protective section (3) on the upper material (1), or the hole (13) is cut by a laser. The dia. of the cut circles (5) is greater than half the width of the fabrics (1,17), so that their centres (7) lie on theoretical straight lines (6) pitched at an angle ( beta ) to the fabric edges of at least 60 deg . The circles (5) are offset  longitudinally and laterally so that they virtually touch across the fabric width. After the edges of the airbag body have been stitched, a limit tape is passed through the hole (13) and bonded in place to limit the expansion of the bag on an impact.

Each transparency is positioned independently of the thickness of the frame (11) so that the film (16) is placed in the focusing plane.

Inventor: SIEGENTHALER MARCEL DR
IPC: D01G27/04
Filed: 1996-07-31
Abstract: This invention concerns a winding device (10) for producing a roll of batting (12). For this purpose, the batting (14) is wound on a rotating core (H) driven by an endless belt (18). The core can be positioned in a loop (20) of the belt (18) formed between two pulleys (R1, R2) which can be stretched by means of a tension-setting device (22). As the size of the roll (12) increases, the size of the loop increases. At least one (R1) of the deviation pulleys (R1, R2) can be placed between a working position designed to form the loop (20) and an ejection position, into which the pulley can be positioned to eject the roll of batting (12), the belt (18) being stretched when the loop (20) is removed. In addition to the tension-setting device (22), at least one compensating element (R6, R6'', R2, R3, R5, R6') is provided to compensate for at least the greater part of the changes on belt length which arise in certain zones when the adjustable pulley (R1) is moved from a working position to an ejecting position and the belt (18) tightens during removal of the loop (20). On the other hand, the changes in belt length which arise during winding in certain zones as the loop (20) grows larger with increasing size if the batting roll (12) are compensated for the most part by the tension-setting device (22).

Patent DE-19641398-A1 (DE)
Inventor: WOLF ANDREAS DR
IPC: H04Q11/04
Filed: 1996-09-27
Abstract: The invention relates to a monitoring AOM cell (M) assisted method enabling continuous intrasystem determination of bit errors occurring in ATM useful cells on an ATM transmission link (5) wherein monitoring AOM cells are transmitted together with ATM useful cells (N) via an ATM transmission link (5). According to a known method only monitoring OAM cells (Meg) that are transmitted without error via the ATM network are taken into account to determine bit errors in ATM useful cells with the selected address in the cell head. In order to be able to determine almost all bit errors in ATM useful cells with the selected address in the cell head, the invention proposes that monitoring OAM cells recognized as having been transmitted defectively (Mes) should be corrected and converted into error-free monitoring OAM cells (Mek) and these monitoring OAM cells (Mek) are taken into account in order to determine bit errors occurring in ATM useful cells received.
