Patent DE-3335495-A1 (DE)
Title: Combination tool
Inventor: HAUG DIETER
IPC: B25F1/04
Filed: 1983-09-30
Abstract: In a combination tool, the tool shank has a displaceable threaded sleeve which, in one working position releases the tool situated in the end region of the tool shank, and in the other working position covers this end region. The other tool part consists of a striking head which can be used as a hammer and is embedded in a plastic moulding which, in the one working position serves as hammer head and in the other working position serves as handle for the tool seated in the tool shank. The locking of this moulding on the tool shank is achieved by a threaded sleeve which acts either on the end face of the moulding or its circumferential surface, preferably engaging by an external thread into corresponding internal threads on the end face or circumferential surface of the moulding. The use of the additional handle sleeve on the one hand and the method of locking by the threaded sleeve on the other hand ensure safe handling and a reduction in the risk of injury when the combination tool is used in practice.

Title: Stepping motor for electronic clocks
Inventor: VECER JOSEF DIPL ING
IPC: G04C13/11
Filed: 1983-11-03
Abstract: The stepping motor for electronic clocks according to the invention supplies a higher load torque with a lower power consumption at the same time, and makes it possible to use cheaper permanent-magnet materials, primarily ferrite, for the rotor. The pole pieces of the stator laminates 1a, 1b are designed to be non-concentric with respect to the rotor 2 and have diametrically opposite recesses 11b whose height corresponds either to the thickness of a stator laminate layer 1c, 1d, at least two laminate layers being provided, or whose height is less than the thickness of the stator laminates, and only a single laminate layer need be provided. The recesses 11d are bounded by two straight lines X' and X'', the straight line X'' running through the rotor axis dividing the air gap 4 into two halves and enclosing an angle  beta , which is greater than 15 DEG , with the Z-Z' axis. The straight line X' encloses an angle  alpha  of less than 130 DEG  with the Z-Z' axis. Stator laminates without and with both types of recesses may be of different thickness. The invention can be used in all types of crystal-controlled electronic clocks having an analogue time display. <IMAGE>

Title: Device for the processing of field crops
Inventor: KLINNER WILFRED ERWIN
IPC: A01D57/12
Filed: 1983-11-30
Abstract: The field-crop processing rotor for the conveying and/or processing of feed crops has a number of carrier elements (12, 14, 14A) and a plurality of field-crop processing elements (11) extending outwards. Each field-crop processing element (11) has an elongate strip (20) which is made of a rigid elastic plastic and which is folded, in order to form two arms (21 and 22) extending outwards in a V-shaped manner. The folded strip (20) is fastened to a supporting flange or supporting leg (14A) via a bolt (23) and a supporting arm (50) which encloses a base portion of the element (11). The bolts (23) extend through a rubber cone (24A) which presses the element (11) against the flange or leg (14A), but allows the element (11) to give way in a pivoting movement away from the flange (14A). An extension (50A) projects from the bottom of the supporting arm (50). When the processing element (11) gives way, the supporting arm (50) pivots, with the extension (50A) coming into contact with the underside of the flange or leg (14), and the bolt (23) becomes set obliquely relative to the flange or leg (14A). <IMAGE>

Patent DE-3345182-A1 (DE)
Title: Circulating surface/track system for supporting loads and forces and for transmitting torque
Inventor: UMLAUF NORBERT
IPC: B21C1/30
Filed: 1983-12-14
Abstract: In track pulling and braking structures (Fig. 7) and in rolling vehicle transporting systems (Fig. 8), it is necessary to support large forces and to transmit considerable amounts of torque. The pressing forces are a multiple of the horizontal forces, depending on the coefficient of friction u and regardless of whether the upper or the lower track system is driven. Exploitation of up to the entire surface in the pressing region is achieved by exploiting the supporting width up to the track division (T) and making the exploited width lie within the centres of rotation. The track segments (4a-d) are obtained in accordance with the permissible load by up to X support points in the form of a roller or rollers or sliding surfaces. Support is provided by the guide surfaces (9). If the circulating surface/track system is used in rolling vehicle transporting systems, the very high load bearing capacity of rolling vehicle transporting systems is maintained. The previous linear contact between the rollers and the bearing surface (7) is replaced by contact over a relatively large area. The rolling resistance is considerably reduced for an unprepared external bearing surface as rolling is carried out in running troughs. This applies especially to uneven and elastic bearing surfaces such as concrete or carpeted floors. <IMAGE>
Patent DE-3401164-A1 (DE)
Title: Multi-phase circuit for the armature winding of electrical machines and frequency converters
Inventor: WEH HERBERT PROF DR ING
IPC: H02K1/27
Filed: 1984-01-14
Abstract: Multi-phase windings allow relatively high force intensities and a more favourable operating behaviour (higher efficiency) to be achieved for electrical machines, particularly if they are supplied by convertor. The proposed method overcomes disadvantages of known solutions, has little reaction and manages with a small number of semiconductors. If odd numbers of phases and an alternately changed winding direction of the phases are used, reaction-free switching results for current waveforms having a gap or having linear commutation within a phase division. If other current waveforms are to be implemented, a balancing circuit is additionally used. Sub-division of the voltage sources can hence be avoided. The circuit can be used for highly demanding control tasks and for high power requirements.

Title: Optoelectronic contact system
Inventor: STOECKL GEORG DIPL ING
IPC: G01B11/02
Filed: 1984-02-27
Abstract: A description is given of an optoelectronic contact system in which a light beam (2) impinges at an angle not equal to 90 DEG  on a surface (4) that is to be contacted, and an evaluation circuit determines the contact from the displacement in the position of the reflected light beam (5). According to the invention, an optical system (L2) switch which focuses a punctiform light source (3) onto the desired position of the surface (4) and a further optical system (L3) are provided, the latter focusing the reflected light beam (5) in the plane (6) of a spatial filter. In order to determine the contact, the evaluation circuit acquires the lateral deflection of the point of light in the plane of the spatial filter or in a plane conjugated with said plane via a positive lens (L4). In order to determine the tilting of the surface (4) to be contacted, the evaluation circuit evaluates the displacement of the centre of gravity of the energy of the divergent beam (8) downstream of the plane (6) of the spatial filter. In the preferred exemplary embodiment, the evaluation circuit has a single-axis positionally sensitive photodetector (9) for determining the lateral deflection of the focused point of light. <IMAGE>

Title: High-pressure catheter with a cutting and/or abrasion device
Inventor: SCHUBERT WERNER DR MED
IPC: A61B17/22
Filed: 1984-06-08
Abstract: If water emerges at high pressure through a nozzle it can be used for cutting, and this effect was utilised by Japanese researchers for severing the hepatic tissue of a rat with a water gun or nozzle which had a diameter of only 0.2 mm, using 10 atm. If these conditions are extrapolated to a pressure-tight catheter, called high-pressure catheter by me, 17.5 atm are necessary for this purpose according to calculations. Such high-pressure catheters can be inserted transluminally via the skin in stenosed or partially occluded pathways in the body, for example highly sclerosed coronary arteries for the gentle re-opening of pathological occlusions of pathways and for elimination of numerous stenoses. If segmentally arranged nozzles which are located obliquely toward the back and proximally on the nozzle head and form foci or coherent foci annularly are used and if the foci of the nozzle jets project above the lateral outer edge of the nozzle head, an abrasion effect is obtained at the front of the high-pressure catheter in addition to the forward motion, and this should also be utilised for the preparation of effective curettes, for example for extraction of the endometrium.

Title: Emission-free fuel-dispenser valve for refuelling operations
Inventor: PETRI GUENTER
IPC: B67D7/54
Filed: 1984-09-05
Abstract: To avoid the hydrocarbon emissions which occur in the hitherto customary manner of refuelling motor vehicles - which amount to about 33000 t of fuel per year in the Federal Republic of Germany - a refuelling system has been developed which, in addition to solving the problems of environmental pollution and saving energy, also solves the problem of fuel theft and, by speeding up refuelling operations, leads to time savings which can be exploited by petrol stations to enhance their development as supply and disposal stations and communications stations. This is achieved by the construction of an emission-free fuel-dispenser valve which is characterised by a flexible seal for the internal seal in the filler neck, incorporation of supply and disposal lines into one hose and integration of all the operating and indicating elements into the fuel-dispenser valve.
