Patent DE-4026961-A1 (DE)
Inventor: LEICHTHAMMER JUERGEN
IPC: F24F13/14
Filed: 1990-08-25
Abstract: A swirl generator for an air outlet of a ventilating installation having a tube with an inlet opening and with an outflow opening designed as an outflow nozzle, which is provided with a plurality of radially outward-pointing swirl vanes held by a hub arranged centrally in the tube, each having a swirl vane spindle and being adjustable as regards their angle of attack, is to be developed further in such a way that the matching and adjustment work is reduced and the adjustment of all the swirl vanes of a swirl generator can be carried out simultaneously, and is also to be simple and economical to manufacture and simple to operate in use, if required by remote control. For this purpose, it is proposed that the hub (11) arranged in the air outlet (1) should be of two-part design and have a hub body (11.1) with at least one bearing collar (12) having bearing grooves (12.1; 12.2) for the swirl vane spindles (21) and have an adjusting part (11.2) which can be connected to the said hub body, can be rotated adjustably relative to the said body and is provided with driving means which interact with the swirl vane spindles (21) in such a way that a rotation of the adjusting part (11.2) about an axis lying in the direction of the air outlet (1) results in a rotation of all the swirl vanes (20) about their swirl vane spindles (21), the swirl vane spindles (21) being aligned transversely to the direction of the air outlet (1). <IMAGE>
Patent DE-4027285-A1 (DE)
Inventor: THIEME JUERGEN DR
IPC: G21K7/00
Filed: 1990-08-29
Abstract: The X-ray microscope has a pulsed X-ray source which supplies an intense line radiation such as, for example, a plasma focus source, a reflecting condenser which focuses the radiation of the X-ray source onto the object to be examined, and a X-ray optical system which is constructed as a zone plate and by means of which the object is projected at high resolution onto an X-ray detector. 
<??>By means of this combination, it is still possible in conjunction with a high resolution free from image defects simultaneously to release at the sample point on the imaging side a satisfactorily high level of X-ray energy, thus producing the short exposure times necessary for the examination of living cells.

Patent DE-4030266-A1 (DE)
Inventor: ALTEN KURT
IPC: E06B7/16
Filed: 1990-09-25
Abstract: The invention is based on a deformable seal for the gap between the edge of an opening in a building and the tail of a vehicle drawn up to said opening, in which a deformable apron which rests against the vehicle is provided at a distance from the building and a roof awning (7) leading to the building is arranged above the apron, said awning protruding at both sides beyond the seal and hanging down freely there. To ensure that the apron and the supporting bodies (10) bearing it are sufficiently deformable when a vehicle comes into contact with them, the invention proposes that the lateral overhang (8) of the roof awning be weighted down at the edge by, for example, inserting a bar (13), e.g. a steel bar, into an edge loop (11).

Title: Improved burn IC engine with two spark plugs - uses staggered ignition for enhanced compression of fuel-air mixture in main combustion chamber
Inventor: HAPPEL ROBERT
IPC: F02P15/08
Filed: 1991-07-17
Abstract: The engine uses two spark plugs, with one plug (11) directly in the cylinder head and the other (10) operating on a separate chamber (8) linked to the cylinder by a shaped duct (7). The first plug fires first, and warms the fuel/air mixture. This enhances the compression ready for a plasma beam ignition via the second plug. The first ignition pulse is before TDC. Additional compression into the separate chamber enables the second plug to generate a plasma stream which is directed onto the top of the piston at an angle. This beam is spread over the piston surface to provide a rapid burn inside the cylinder. ADVANTAGE - Improved burn, improved efficiency, simple ignition control.

Title: Breech head for gun with locking bolts to hold breech in position - has mechanism which prevents firing of gun unless both locking bolts are in place
Inventor: MENGES HORST
IPC: F41A17/66
Filed: 1992-03-07
Abstract: The gun breech (2) is housed in the breech head (1) and has a stepped central bore to receive the firing pin (4) which is pressed rearwards by a spring. The breech is locked in the breech head by two sliding bolts (8,9) in guides (7), engaging the undersurfaces (10) of the lugs of the breech. A lever (11) is mounted on a pivot (12) in a longitudinal slot on each side of the breech. Each lever has a projection (15) which limits the axial movement of the firing pin, when radially projecting lugs (16) on the firing pin abut against the projections. When the breech is locked in the head, the levers are rotated against the force of attached leaf springs (14) and allow the firing pin to be moved against the force of a compression spring (5). If only one bolt is engaged, the lever on the opposite side remains in the position to prevent the axial movement of the firing pin. ADVANTAGE - Firing prevention on incomplete locking.
