Title: Screw propeller for the propulsion of watercraft
Inventor: KEMPER KARL-HEINZ
IPC: B63H1/14
Filed: 1988-05-24
Abstract: To improve the efficiency and take up higher loads in the propulsion of watercraft which are driven by screw propellers, a screw blade is run completely or almost completely around the propeller shaft with a constantly increasing pitch angle which is adapted to the law of acceleration. In order to maintain an optimum pitch angle of the screw blade near the shaft, the screw blade is increasingly recessed at the shaft. Accordingly, the outside radius of the screw must be increasingly enlarged towards the shaft end so that the surface area of the screw blade is retained, whereby a favourable pitch angle is likewise achieved.

Patent DE-3917080-A1 (DE)
Title: Roller blind
Inventor: RITZENTHALER WALTER
IPC: E06B9/34
Filed: 1989-05-26
Abstract: The roller blind (1) comprises a first number of rotary lamellae (20) and a second number of rigid lamellae (30). The two types of lamellae (20, 30) are secured, by means of first pins (21), on a strand (23, 33) which is fastened on a winding spindle (11). A second strand (24) is fastened in a retaining means (40) and serves to secure the rotary lamellae (20) in that second pins (22) are fastened on it. The retaining means (40) has a retaining lug (45) which interacts with a stationary pin (50) and, upon abutment, fixes the second pins (22). Further lowering of the first pins (21) effects a rotation of the rotary lamellae (20). The force required for said lamellae (20) to rotate is applied by the weight of the rigid lamellae (30). Satisfactory functioning of the rotary lamellae is thus ensured, the material outlay being only a small amount greater than in the case of conventional roller blinds which do not have the advantage of providing selectable degrees of shading for rooms. <IMAGE>

Title: Bobbin yarn reserve - uses unwound preset length drawn into a store by the doffer and then rewound at the head end of the bobbin
Inventor: SCHWALM HANS-WERNER
IPC: B65H67/08
Filed: 1990-02-10
Abstract: To form a yarn reserve winding on a cross-wound bobbin, pref. at the head end using the doffer, a pre-set yarn length is used as the reserve, which is unwound from the bobbin to be held for itnermediate storage. A sensor registers that the yarn reserve length is present in the store. When the required length has been unwound, the bobbin is stopped and its rotation is reversed back into the winding direction while the reserve yarn length is positioned at the head end and wound round the bobbin at this section through the bobbin rotation. As the yarn reserve length is drawn out of the store, a brake action is applied to maintain the reserve yarn tension. The yarn unwinding from the bobbin is pref. stopped when it is registerd by the sensor, or, when the sensor registers the yarn, the bobbin unwinding is stopped after a given time delay. The search for the yarn end, at the cross wound bobbin, is stopped when the sensor has not registered its presence after a given time span and a fault signal is generated. The reciprocating movement of the yarn in the store is generally suppressed and positioned at the head end of the bobbin to be in the right place for rewinding as the reserve and any surplus length is trimmed. A sensor positions the yarn at the head end of the bobbin. A suction air stream is used to search for the yarn end at the bobbin, which also draws the yarn end into the store, through a suction tube applied to the surface of the wound yarn on the bobbin.
