Patent DE-3327046-A1 (DE)
Title: Clamping tool for threaded shanks
IPC: B23B31/02
Filed: 1983-07-27
Abstract: The tool (10), provided for clamping threaded shanks (12) provided with an external thread, has a shank holder (14) which can be inserted in a drive machine. At its end opposite the mounting end, the shank holder (14) is provided with a hollow bore (24) which, by longitudinal slots (26) made in it starting from its insertion aperture for the threaded shank (12) to be clamped, is subdivided into a number of clamping arms (28) which can be expanded elastically in the radial direction. In the area of the insertion aperture, the outer surfaces of the clamping arms are designed as a clamping surface (30) complementing one another to form an overall frustoconical surface, while on their inner surfaces opposite the clamping surface they have a mating thread (32) complementary to the thread of the threaded shank (12) to be clamped. By a clamping sleeve (16) which overlaps the area of the insertion aperture, is screwed onto an external thread of the shank holder (14) and has an inner frustoconical clamping surface complementary to the clamping surface (30) of the shank holder (14), the clamping arms (28) can be pressed together from their radially expanded insertion position, enabling the insertion of the threaded shank, into a clamping position brought radially closer and holding the inserted threaded shank. <IMAGE>

Title: DC pulse converter
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M3/155
Filed: 1983-09-29
Abstract: This DC pulse converter is a "step-down converter", that is to say the output voltage of the converter is less than the voltage applied to the input side. Such step-down converters can be used, for example, as battery chargers. An electronic switch (1), for example a transistor, and a storage inductor coil (4) are arranged in the lead train of a terminal. In this case, the inductor coil (4) is split into two winding elements (5, 6), and a freewheeling diode (12) is connected to the inductor tap thus formed. The freewheeling diode (12) carries the current on the output side when the electronic switch (1) is switched off. Since only that winding element (6) which is located in this freewheeling circuit has to be designed for the full output current, the physical size of the inductor coil (4) can be designed to be smaller. Furthermore, the switching-on (making) capacity of the electronic switch (1) rises while the current flow is at the same time reduced. <IMAGE>

Title: All-wheel drive motor vehicle
Inventor: OBERKOBLER THOMAS
IPC: B60K17/34
Filed: 1984-05-04
Abstract: In an all-wheel drive motor vehicle with continuous, that is non-engageable drive of the front axle and the rear axle, a first differential is provided for balancing the difference in travel between the left front wheel and the right rear wheel and in addition a second differential for balancing the difference in travel between the right front wheel and the left rear wheel (diagonal drive circuit of the wheels). First and second differential are of essentially identical design and lie in a tandem arrangement on one wheel axle (front or rear axle). Between the two differentials a double angular gear is connected, which also transmits the rotary force to the second axle of the motor vehicle by way of longitudinal shafts and angular gears of the second axle arranged concentrically in one another. For each differential a differential lock is expediently provided, both differential locks being coupled to the steering and operated as a function of the steering in such a way that in straight running with little steering movement of the one steered axle both differentials are locked, and in the event of a certain steering angle being exceeded, in order to accommodate an increased steering movement only that differential is released by the corresponding differential lock for balancing of the travel which has the greater travel balancing to perform. In this way a very good all-wheel drive is created at low design cost, which ... Original abstract incomplete.

Patent DE-3432797-A1 (DE)
Title: Method for electric resistance seam welding with just one electrode wire and a welding machine for carrying out the method and the application of the method
Inventor: OPPRECHT PAUL
IPC: B23K11/06
Filed: 1984-09-06
Abstract: For the electric resistance seam welding of tin plate, welding machines with wire electrodes are used. If only one electrode wire, running over both electrode carrier rollers, is used, a hard wire is required to prevent loop formation in the wire winding between the electrode carrier rollers. Hitherto, this has been produced by rolling a soft round wire. However, this rolling process produces uneven hardness distribution over the cross-sectional area of the wire, with zones of high material work hardening and zones of low material work hardening, with the result that the average increase in the strength of the electrode wire in relation to the total cross-section of the wire is always below the increase in strength which could theoretically be achieved if it were not for the fact that part of the cross-section of the wire does not participate in the high material work hardening. A closer approximation to this theoretical increase in strength has been achieved by replacing the rolling process with cold deformation in several steps. In this process, the round wire is drawn to a smaller diameter in a first deformation stage and then subjected to cold deformation in a second deformation stage by rolling flat. In addition to advantages in terms of welding, this also results in significant savings of wire.

Title: Process for digesting cereal grains
Inventor: JODLBAUER HEINZ DR
IPC: A23L7/10
Filed: 1985-02-18
Abstract: The invention relates to a process for digesting cereal and legumes.   The invention is based on the object, in contrast to the hitherto known prior art, as already mentioned, of effecting the entry of water into the material (for example cereal grains) in order thus to achieve the corresponding potential reactions, without as a result of too high an energy at too low a dipole moment, for example, burning or roasting proceeding during this. This object is achieved according to the invention by subjecting various types of cereal (wheat, rye, maize, millet, barley, rice and legumes such as beans and peas) to a microwave treatment to the effect that these cereals are treated with various water contents preferably between 10 and 15% at various energy levels, according to the desired degree of digestion of the constituents of the cereal; the degree of digestion is controlled by chemical analyses as shown in Example 1 and 2.

Title: Valve for drinking basins for animals
Inventor: VOLZ HERMANN DIPL ING
IPC: A01K7/06
Filed: 1985-10-16
Abstract: The invention relates to a valve, actuated by a pressure flap, for drinking basins for animals, having a valve cone which is arranged in a valve body and closes in the flow direction of the water, and having a valve spring which is tensioned between the valve cone and a spring abutment fastened on the valve body, the valve body together with the spring abutment forming a water chamber around the valve spring and the valve-side end of the valve cone and the water chamber being connected to the water supply through an opening in the spring abutment. In the case of said valve, the object of the invention is to avoid a non-stable operating state which occurs, in particular, when relatively large quantities of water flow through. In order to achieve this object the invention essentially proposes that the opening in the spring abutment be assigned a plug which, in dependence on the position of the valve cone, at least approximately closes off the opening when the valve is closed, releases the opening in a delayed manner when the valve cone is pressed in and, on the other hand, closes off the opening again earlier when the valve cone is closed.
