Title: Universal screw clamp
Inventor: HUMBS LORENZ
IPC: B25B5/06
Filed: 1988-03-18
Abstract: With the known screw clamps, many connection problems cannot be solved. The novel screw clamp is to make possible connections which have hitherto not been practicable, by means of multiply and variously usable screw spindles and by the variety of joining possibilities of a plurality of clamps. The object is achieved in that u-shaped bows are produced from Halfeneisen TM  with rear-side partial slots (1), in the case of which bows the possibility exists, with the aid of inserted hammer-head threaded plates (2) in the region of the slots, of screwing on further screw-clamp units or screwing in screw spindles (3) with removable pressure plates (4). With the aid of attached scales (5), the clamps can be connected at defined angles. Rubber profiles (6) are provided to avoid pressure marks on the clamped-in materials. The universal screw clamp is suitable for the construction of working frames, for the connection of decorative elements and also as a universal working aid for known and new connections. <IMAGE>

Title: Safety motor vehicle with an air duct formed between roof and front roof extension
Inventor: AMBROS RICHARD
IPC: B60S1/04
Filed: 1988-11-12
Abstract: A safety car whose air resistance value is almost as good, despite a front roof extension (580) provided over a windscreen (26), than the air resistance value of a car without front roof extension. Here, an air channel (583) which is formed by a front roof spoiler (582) is formed between a double-walled roof and a double-walled front roof extension (580) into an overroof that also extends over a rear window (26a) and the side windows so that an airstream which is directed against the windscreen can escape upwards over the roof, which is also illustrated in the utility model publication G 8708561.5 (BRD) where a conventional passenger car is illustrated with a double-walled front roof extension attached to the roof, and we acknowledge this freely. For a well metered application of water to the windows (26 and 26a), collection troughs (240, 159 and 159a) for rainwater are formed in the base of the overroof, a roof spoiler (593) being formed in a rear roof cover (39a) over a collection trough for the rear window directly in front of the longitudinal slots provided for the trough in the cover of the roof so that as a result a continuous passage of air through the double-walled roof is achieved. <IMAGE>

Patent DE-3900298-A1 (DE)
Title: Pneumatic swivel drive with a curved piece which can be modified
Inventor: BARKHOFF REINKE DIPL ING
IPC: F15B15/08
Filed: 1989-01-07
Abstract: In conventional swivel drives, the user must limit the angle of rotation by stops or have recourse to expensive special constructions. Drives with spring restoring considerably weaken the available torque. The curved piece of the swivel drive is produced for the angle of rotation required in each case. This is done by twisting a flat material blank in a device. Consequently, no extra cost in terms of production ensues. To fasten the curved piece, a spindle neck is provided which simplifies an adjustment to the zero position. A spring for the restoring can be dispensed with. The restoring force raises a supply of air, the pressure of which build completely only after the working cycle. <IMAGE>

Patent DE-3905329-A1 (DE)
Inventor: SCHNYDER EUGEN
IPC: F16C35/073
Filed: 1989-02-17
Abstract: The invention concerns a pressure roller (3) with a shell (2) which is mounted to rotate about a fixed carrier (4) and which can be moved relative to the carrier (4) over the whole of its length along the pressure plane by means of pressure-adjustment elements (5) located between the shell (2) and the carrier (4). So that it remains in the pressure plane, it has a guide mounting (1) with a bearing, comprising an inner ring (6) and an outer ring (8), between the shell (2) and the carrier (4). Means (9) are associated with the bearing to guide the bearing substantially parallel to the pressure plane. The inner ring (6) of the bearing is fixed onto the outer surface of an annular section (7) of the shell (2). The outer ring (8) of the bearing carries two strips (9) running parallel to the axial plane of the ring and which form between them the guide surfaces for an elongated guide crank. Provided on the carrier (4) are two guide surfaces (10) which are parallel to the pressure plane. The distance between these guide surfaces is matched to that between the crank guide surfaces to give a sliding fit. This ensures that the outer ring (8) cannot be rotated, but the shell (2), which can be rotated with respect to the outer ring, is guided, with the outer ring, to move parallel to the pressure plane.
