Patent DE-3106942-A1 (DE)
Title: Rig with double sail
Inventor: JUNG OTTO DR MED
IPC: B63B35/79
Filed: 1981-02-25
Abstract: In conventional rigs, a technical problem stems from the aerodynamic rule that the efficiency of a sail is inferior to the efficiency of a profiled wing. This disadvantage can be avoided by a double sail with an adjustable asymmetric wing profile. To solve the technical problem, a folding square sail is used, which according to Fig. 1 is folded into a double sail (1) in the area of the vertical centre line and encloses the mast (2). Here, the clews (4, 4') of the double sail (1) are connected to the spar of the boom (3), which is attached to the mast (2) in a rigid or articulated manner. When a windward sail is set in a flat or concave manner and a lee sail is set in a convex manner, the double sail (1) serves as an adjustable wing with an asymmetric wing profile. Main use is sailing or windsurfing at maximum speed. <IMAGE>

Title: Control system for the fuel/air ratio of an internal combustion engine
Inventor: OHGAMI MASAAKI
IPC: F02D41/14
Filed: 1981-03-06
Abstract: The control system for the fuel/air ratio of an internal combustion engine comprises an intake duct, an exhaust pipe, a feed device for the fuel/air mixture, an electronic ON/OFF valve for correcting the fuel/air ratio of the fuel/air mixture which is fed by the feed device for the fuel/air mixture, a circuit which produces a periodic jitter signal, a displacement control circuit which displaces the level of the centre of the jitter signal, a drive circuit which produces a drive output for the electromagnetic ON/OFF valve and an O2 measuring sensor which detects the oxygen concentration in the exhaust gases flowing through the exhaust pipe. In this arrangement, a first circuit is provided which detects a mean value between the maximum value and the minimum value of the output voltage of the O2 measuring sensor in each cycle, and a second circuit which detects a mean value between the area of an upper region bounded by the wave-line above a previously determined reference value and the area of a lower region bounded by the wave-line below the previously determined reference value. A circuit which produces a displacement signal is provided in order to compare the outputs of the first and second circuit and produce a displacement signal which corresponds to the difference. The displacement control circuit is configured in such a way that it controls the fuel/air ratio of the mixture in such a direction that the difference is reduced. <IMAGE>

Title: Fuel transfer cask having an anticontamination shroud
Inventor: CHARVAT ZDENEK DIPL ING
IPC: G21F5/008
Filed: 1981-04-08
Abstract: In the case of fuel transfer casks, an attempt is made to use an anticontamination shroud (8) made from flexible material and surrounding at least large parts of the cask surface in order to limit contamination. However, this can complicate the dissipation of heat. In accordance with the invention, the interspace (11) between the protective shroud (8) and the surface is reduced to a value which is no longer disturbing in practice. The interspace (11) can be evacuated for this purpose. Alternatively, the plastic of a protective shroud (8) can be shrunk onto the surface. <IMAGE>

Patent DE-3122663-A1 (DE)
Title: Wind power installation
Inventor: GREFF EBERHARD
IPC: F03D1/04
Filed: 1981-06-06
Abstract: A wind power installation consists of a vane-like body against which the wind can flow and which has at least one sharp edge which can be set obliquely relative to the wind and around which an equalisation of pressure is produced which forms an eddy. The installation also consists of at least one rotor which is arranged in the flow direction downstream of the edge against which flow can occur. The rotor serves to provide drive, and its axis is situated in the region of the respective eddy core. In order to permit a sufficiently large concentration of wind energy and, in particular, to achieve a good eddy stability, the edge, which can be set obliquely relative to the wind, of the vane has a rim bend which is curved in the direction of the eddy along its entire length. The blade twisting of the rotor is aerodynamically adapted to the eddy field.
Patent DE-3123120-A1 (DE)
Title: Tension member for a resin bolt
IPC: F16B13/14
Filed: 1981-06-11
Abstract: An annular body (7) made of an elastic material, such as, for example, rubber or plastic, is arranged at the borehole-side end of a tension member (2) for a resin bolt. The annular body (7), sealing the annular space (8) between the tension member and the borehole wall (9), frictionally encloses the tension member (2) in such a way that it can be displaced along the tension member (2) upon insertion of the tension member (2) into the borehole (1) while exerting pressure on the synthetic resin (12). Resin flowing back, for instance, will be stopped by the annular body (7) directly after destruction of the cartridge and will be thrust back under compression. The frictional connection between the annular body and the tension member is so great that, when the tension member is screwed in onto the resin, which at first is pasty after the intermixing, a limited pressure is applied in the direction of the borehole end, while the tension member itself is pushed through the annular body with this pressure being maintained. <IMAGE>
Patent DE-3123672-A1 (DE)
Title: Friction false twister
Inventor: OBERSTRASS DETLEF
IPC: D02G1/08
Filed: 1981-06-15
Abstract: The invention relates to the drive of a friction false twister, which consists of two rotating friction surfaces (crossed belts or overlapping pulleys) which clamp and false-twist a thread between their working faces. The drive by means of a tangential belt driven in a constant running direction is brought about by a main wharve and is transmitted from this, via a drive belt, to the belt pulley (wharve) of the false-twist generators. An always constant belt tension is maintained by force generators (springs) which act on associated deflecting rollers. The drive takes place in that a simple change-over from S to Z false twisting is possible on the false-twisting unit and the belt tension is automatically kept essentially constant for all the units of the machine, irrespective of their particular setting for S or Z twisting.

Title: Transport vehicle, in particular a trailer vehicle or the like
Inventor: KOCH RICHARD DIPL ING
IPC: B60P1/02
Filed: 1981-06-24
Abstract: Transport vehicle, in particular a trailer vehicle, having running wheels (18) rotatably mounted by means of rockers (16) on the frame (14) of the vehicle, the rockers (16) being coupled in each case to an actuating element (piston-cylinder unit 10), mounted on the frame (14), specifically via a coupling element (12) in such a way that, by actuating the actuating elements (10), the rockers (16) can be swivelled in relation to the frame (14) and thus the frame (14) can be lowered or raised parallel to its horizontal position. The operative connection between the actuating elements (10) and the wheel rockers (16) via the coupling elements (12) is such that, in the travel state of the vehicle, that is to say with the vehicle frame (14) is raised, the running wheels (18) are supported on the vehicle frame (14) in each case only via the rockers (16) and the coupling elements (12) and the actuating elements (10) are thus relieved. Preferably, the coupling elements (12) are constructed in each case as resilient legs. At the same time, the frame lifting device, formed from the actuating element (10), coupling element (12) and wheel rocker (16), is coupled to a towbar (14), which is attached to the frame, in such a way that the connecting or coupling part of said towbar is always held approximately at the same level irrespective of the height of the frame (14). In order to improve the travel characteristics, the wheel rockers (16) are additionally fixed to the frame (14) of the vehicle via follow-on and lateral guides (30). <IMAGE>
Patent DE-3125034-A1 (DE)
Title: Valve, in particular for vacuum systems
Inventor: SCHERTLER SIEGFRIED
IPC: F16K41/10
Filed: 1981-06-26
Abstract: The valve, which is intended for vacuum systems, in particular for high vacuum systems, has a valve spindle (8) which bears a closing element. This closing element consists of two discs (10 and 18) which can be displaced axially relative to one another and are obliquely or conically chamfered at their mutually facing ends to form a V-shaped groove (21). A sealing ring (22) of permanently elastic rubber-like material lies in this groove. As a valve housing use can be made here of a simple, commercially available, seamless drawn or extruded piece of tube (1). Attached to the side of this piece of tube (1) is a further piece of tube (2) of the same construction. Cut into the inside of the first-mentioned piece of tube (1), below the point of attachment of the piece of tube (2), is a groove (23) into which is inserted a spring ring (24). When the valve closes, one disc (18) strikes against the spring ring (24) and is thereby held fast. The further movement of the valve spindle in the direction of closing presses the disc (10) against the now stationary disc (18). As a result, the width of the V-shaped groove (21) is reduced and the flexible sealing ring (22) is expanded radially and rests sealingly against the inside of the valve housing (1). <IMAGE>

Patent DE-3214748-A1 (DE)
Title: Oscillator circuit
Inventor: HANSEN JENS DIPL ING
IPC: H03L7/23
Filed: 1982-04-21
Abstract: An oscillator circuit having a reference frequency source (10) and a PLL control loop (25) is proposed in which the inherent noise of the voltage-controlled oscillator (19) and the fluctuation in the output voltage (fO) of the oscillator are to be prevented. For this purpose, a frequency (fA) is derived from the output frequency (fO), which acts as reference frequency for a second voltage-controlled oscillator (29). The second voltage-controlled oscillator belongs to a second PLL control loop (26) which only handles the long-time stability of the derived frequency. The second voltage-controlled oscillator produces the short-time stability of the first voltage-controlled oscillator via a frequency-dependent transfer network (36,37). <IMAGE>

Title: Process and apparatus for producing a cleaned fibre stream
Inventor: RAASCH HANS
IPC: D01H4/32
Filed: 1982-06-05
Abstract: In order to obtain a fibre stream consisting of substantially cleaned individual fibres, the fibre sliver (21) containing impurities is supplied at a feed point (7) to an opening roller (3), where fibres and foreign particles are picked up by the clothing (15) of the latter. At a narrow point (16) located behind it, the coarse foreign particles are thrown off in the form of an irregular particle jet (23). An air stream guided on a circular path by the clothing takes up the individual fibres and carries them, lighter foreign particles being carried further first. They are then removed from the annularly guided air stream (29) under the effect of an external force. Only thereafter is a directional air stream (28), being compressed in a fan-shaped manner with an increasing flow speed, introduced tangentially into the clothing, where it combines with the circularly guided air stream (29). Any spinnable fibres which have already escaped from the clothing are picked up again by the directional air stream (28). All the spinnable fibres are reformed, accelerated again and drawn. Thereupon, the fibre stream (33) now already cleaned is extracted from the clothing (15) by means of the air stream (28) in tangential contact with the clothing (15) and the opening roller (3) and is transferred to the rotor of the open-end rotor spinning machine by means of a feed channel (32). <IMAGE>

Title: Target control device for elements movable along a movement path
Inventor: KLIMKEIT HANS J DIPL ING
IPC: B65G47/49
Filed: 1982-07-08
Abstract: In a target control device (1) for elements (3) movable along a movement path (2), for example for machines, in conveying systems or the like, with at least one radiation transmitter (4) for transmitting information and at least one radiation receiver (5) to receive information, a contact-free, reliable and faultless information transmission or address reading even and especially at high movement rates, is guaranteed by the fact that the radiation transmitter (4) and the radiation receiver (5) have a transmission characteristic encompassing a large beam angle ( alpha ) and a reception characteristic encompassing a large acceptance angle ( alpha ). This thus provides the possibility, even at high movement rates of the movable elements (3), of reaching adequate overlapping times, so that the main cause of incorrectly read addresses is eliminated and especially a ''fluttering'' of the movable elements (3) no longer causes disturbance. <IMAGE>
