Patent DE-4223648-A1 (DE)
Inventor: LUEHR GUENTHER-HANS DIPL ING
IPC: B01D53/94
Filed: 1992-07-17
Abstract: A catalytic converter housing (1) has a funnel-shaped end-section (5), a monolithic catalytic body (3) supported by an expanded mat (2) within the housing (1), and an inner funnel (7) close to the end-section (5). The end of the inner funnel (7) adjacent to the catalytic body (3) rests on the housing (1) to overlap the expanded mat (2), while the opposite end of the inner funnel (7) is able to move back and forth to compensate for heat contraction and expansion of the housing (1). The novelty is that the inner funnel (7) adjacent to the catalytic body (3) is secured solely by pressure exerted by the expanded mat (2), so that the end of the inner funnel (7) adjacent to the catalytic body can overcome the pressure exerted by the expanded mat (2) and move. USE/ADVANTAGE - The assembly is a catalytic exhaust gas converter for automotive use. The arrangement reduces damage to the inner funnel as a result of expansion and contraction resulting from temp. change.

USE/ADVANTAGE - In laboratories where frequent opening and closing of the container is required.  Easier reliable sealing action always ensured. Can be handled by robot machines.
Patent DE-4243695-A1 (DE)
Title: Electrical drive
Inventor: STARGARD SIEGFRIED
IPC: H02N11/00
Filed: 1992-12-18
Abstract: An electrical drive has already been proposed in which an accumulator consisting of inductors supplies the motor of the electrical drive, after it has been disconnected from the electrical mains power supply after being brought into use. In this case, the accumulator consists of a helical conductor (which consists of one turn having a large external diameter) a winding which is connected in series with this conductor and two asynchronous motors whose power and rotation speed differ. Since these asynchronous motors are subject to particularly stringent requirements, these requirements lead to disproportionately high costs which limit the use of the electrical drive. In order to reduce the structural cost, both the helical conductor (9) (which consists of one turn) and the winding (10) connected in series with it are arranged in a housing (25) which is provided, mounted such that it can rotate, in a fixedly arranged frame (28) and is connected to the shaft (31) of a high-speed infinitely variably controllable electric motor (32). The drive is suitable, for example, for electric cars and electric locomotives. <IMAGE>

IPC: B65H9/10
Filed: 1993-04-29
Abstract: The device (1) for the alignment of sheets in accordance with two sheet stops (3 and 5) extending perpendicular to each other consists of a rotatably supported sleeve (6) in which a plunger (16) is guided. The plunger (16) is held in the sleeve by means of elastic means (18). At least one aligning element (8) is supported pivotably about a pin (10) on the sleeve (6), the said aligning element (8) having a frictional element (14) at one end. Elastic means (24), which connect the aligning element arm (12) to the underside (22) of the plunger (16), effect a specific contact force of the frictional element (14) on the surface (4) of the uppermost paper sheet. <IMAGE>

Title: Acceleration sensor for vehicle-sensitive systems
Inventor: DECKER CHRISTIAN
IPC: B60R22/26
Filed: 1993-05-06
Abstract: An acceleration sensor for vehicle-sensitive systems is composed of a holding part (13, 14) on which there is a mounted an inertial weight (17) which moves a lever (9) or a pusher rod when acted upon by accelerations or decelerations, and of a control catch (4) which is in contact or nearly in contact with the tip (8) of the lever (9) or pusher rod and is pivoted by the tip (8) when the inertial weight (17) is moved out of its rest position by accelerations of a predetermined magnitude. The holding part (13, 14) is movably mounted on a pivotable vehicle part, for example a seat or a seat backrest. The holding part (13, 14) is provided with an adjustment device (21, 23), which, when the vehicle part is pivoted, moves the holding part (13, 14) in such a way that the direction of the holding part (13, 14) is not changed with respect to the floor of the vehicle. In order to ensure that in each pivoting position of the holding part of the acceleration sensor, an essentially equal torque is transmitted by the pulse lever to the control catch, the control catch (4) is provided with a radial cam (10) which interacts with the tip (8) of the lever (9) or pusher rod. The radial cam (10) is shaped in such a way and the holding part (13, 14) is movable in such a way that in every position of the holding part, the tip (8) acts on the control catch (4) with a force which generates an approximately equal amount of torque when it is activated (Figure 1). <IMAGE>

Title: Vane pump
Inventor: VOGT RICHARD
IPC: F04C15/00
Filed: 1993-08-07
Abstract: The invention relates to a seal (21) for limiting a pressure zone (22) at a pressure plate (10) for a vane pump. The pressure plate (10) is pressed against a pump pack (6, 7, 8) by the operating pressure and is axially movable within a gap width "S". According to the invention, the seal (21) is formed in a U-shape so that two sealing lips (24, 24A) are obtained. The seal (21) is fitted into the pump in such a way that the pressure oil can be admitted to the rounded-off end face from a pressure space (20). The sealing lips (24, 24A) and a web (25) therefore bear reliably against the walls of the groove and against a wall of a cap (23) defining the gap. <IMAGE>
