Patent DE-3202812-A1 (DE)
Title: Wind deflector
Inventor: SCHLICK WERNER
IPC: B62D35/00
Filed: 1982-01-26
Abstract: A wind deflector, for reducing the flow resistances in land, air and water vehicles, in which the same forces which act as lift forces on the aircraft main planes are used as traction forces. They are equipped in profile in accordance with the current state of the teaching relating to flow mechanics. Correspondingly, the outwardly directed convex side is more strongly curved than the inwardly directed concave side. Generally, relatively thick profiles with a large nose radius are most suitable for this because they develop the largest pressure and suction forces. They are to be applied in such a way that they are flowed around in the longitudinal direction and the resulting forces act as forwardly directed traction forces. They are made of metal or plastic. They are attached to spacing elements so that the wind deflectors are freely flowed around. The deflector component (x) is equipped in such a way that a favourable flow behind is produced. If the wind deflector is attached in such a way that the upper convex side is directed forwards and obliquely downwards, in addition better road holding is produced together with the traction force in land vehicles. The patent consists in the fact that the wind deflector is to be used universally for reducing flow and resistance, which is equivalent to a saving in energy or a gain in speed, in all vehicles. Whilst the conventional spoiler only produces a greater degree of road holding with a minimum gain in energy by means of counter pressure, with the wind deflector the greater degree of road holding is produced additionally. <IMAGE>

Patent DE-3204337-A1 (DE)
Title: Process and apparatus for forming a thin film
Inventor: NAHARA AKIRA
IPC: C23C14/24
Filed: 1982-02-09
Abstract: A thin film is deposited on a substrate (18) by evaporating a deposition material (4) and converging the vapour stream (V) on the substrate with high efficiency by using a reflecting guide wall which is heated to a temperature at which the vapour is efficiently reflected without adhering thereto. The vapour stream converged in this way is caused to collide with thermoelectrons and be ionised by the latter, and then the ionised vapour is further converged in the desired direction with respect to the substrate by an electrical field. A thermionic electron source (34) and an ionisation promoting electrode (35) are situated above or in the chamber bounded by the reflecting guide wall, or are connected to the guide wall or the furnace (3) which contains the deposition material. <IMAGE>

Patent DE-3218005-A1 (DE)
Title: Method and device for milk extraction
Inventor: HAMANN JOERN DR
IPC: A01J5/007
Filed: 1982-05-13
Abstract: In a method for milk extraction from teats of dairy cattle into a milk drawing-off system of a milking machine working with underpressure, the underpressure of which lies in each case via a supply line in each case at a teat of an udder, the underpressure is for each individual supply line controlled separately from the other supply lines, depending upon the milk flow. Before the milk flow starts, a reduced vacuum is controlled to the teat and after the milk flow has started a barrier preventing the complete vacuum is removed. In the device provided for implementing the method, the supply line is provided with a cutoff, controlled by the milk flow, of the underpressure prevailing in the milk drawing-off system and the cutoff is bridged with a special line, in which a cross-sectional limit is provided.

Title: Control system for a hydraulically driven metal-forming press
Inventor: KEILHOLZ FRIEDRICH DR ING
IPC: B21J9/20
Filed: 1982-06-24
Abstract: To reduce the operating times of the control system and the times for the pressure build-up and the pressure relief in metal-forming presses driven hydraulically by means of pumps and accumulators, in each case an operating line of the main control members for the pressure-medium lines leading to or from the cylinder is controlled by an auxiliary operating element, the actuation of which is effected by another respective main control member of the press control system. The start and end of pressing are quickly and reliably activated when, in the case of the former, the auxiliary operating element for the control of the pressure-medium source is actuated by the stroke movement of the filling valve cone, on which the pressure medium advantageously exerts a force, acting in the closing direction, when flowing into the press cylinder, and in the case of the end of pressing, when the auxiliary operating element for the control of the relief valve is actuated by the stroke movement of the main control member in the connecting line from the pressure-medium accumulator to the press cylinder.
Patent DE-3231282-A1 (DE)
Title: Method and device for producing bottom sockets
Inventor: KRAISS RICHARD
IPC: E03F3/04
Filed: 1982-08-23
Abstract: Production method for bottom sockets, in which the outer ring part is produced from a strip of flat material by bending to form a closed and welded-together flat ring. The inner ring part and the central part are produced jointly and in one operation from an integral, correspondingly wide strip of flat material of the correct length and of the same or different material thickness. The strip of flat material is first of all bent to form an at least approximately cylindrical or frustoconical annular shell and welded together in the region where the ends abut. The annular shell and the flat ring are then firmly connected by welding. At least one part of the annular shell is then formed to give the desired shape, in particular of the central part and/or the inner ring part, by rolling using a roller and a shaping tool to give the finished socket profile. Forming of a completely integral annular shell, formed by a bent strip of flat material welded together, is also possible. The bottom socket has a high dimensional accuracy and can be produced economically without waste and with a low consumption of material.
Patent DE-3234805-A1 (DE)
Title: Connection and carrying device for skis
Inventor: LOEFFELHOLZ EBERHARD
IPC: A63C11/02
Filed: 1982-09-20
Abstract: Transporting cross-country skis is a well-known problem. The device described here consists of a strap which is simply applied in a particular manner to a cross-country ski pole about 1 1/2 hand widths below the pole handle and remains there constantly as a small folded strip. Adhesion elements of a so-called touch-and-close fastener mounted according to the invention - see Figure 4, parts 2 and 7 - hold both this folded strip and, during carrying, the cross-country skis and the second ski pole placed on. The carrying device is supplemented by a special cross-country ski pole basket - see Figure 6, drawings 1 and 2 - into which the ends of the cross-country skis can be inserted in such a way that they are parallel. One advantage is that the cross-country skis can be inserted into the baskets (9) whilst standing upright on the ground and then the strap firstly clamped between the running surfaces of the skis surrounds the skis in front of the binding. A frame of ski, basket, pole and fastening strap is thus obtained which can be carried conveniently by the pole. It is very advantageous that there are no cumbersome devices or devices which have to be carried separately. <IMAGE>

Title: Circuitry for electronic branch pairs in a reverse-parallel circuit
Inventor: MARQUARDT RAINER DR ING
IPC: H03K17/00
Filed: 1982-12-02
Abstract: For self-commutated multi-quadrant converters, which are used, inter alia, in speed-controlled three-phase drives, circuitry is specified, which reduces the switching-on and switching-off losses of the semiconductor switches and diodes. It is particularly suitable for GTO thyristors (thyristors which can be turned off) and MOS field-effect transistors. Because the switching losses and the voltage surges on the semiconductor switches are kept very small, high efficiencies and good power-utilisation of the semiconductor switches result. Apart from the reactive elements - switching-on relief inductor and switching-off relief capacitor - which are required in principle, only one further capacitor is required for intermediate storage of the circuitry energy. The switching-on relief inductor may be formed partially or completely by the stray inductance of the supplying or supplied DC voltage source.

Filed: 1983-02-02
Abstract: In addition to its actual function, namely of covering silage, the movable, vertically adjustable multipurpose roof over the multi-element clamp silo can also be temporarily used as a storage hall or shed. After the silo stack or silo shed assumes a multiple function, it also proves environmentally friendly to a large degree. By virtue of the possibility of extending it, reducing it without difficulty - but also removing it again, environmental damage is avoided completely. The silo stack, also silo shed, or the multi-element clamp silo with its vertically adjustable multipurpose roof will start a new type of silo design in agriculture.

Title: Wood-species domino as a technical means for scientific instruction and artistic design
Inventor: SCHELOWSKY MICHAEL
IPC: G09B1/06
Filed: 1983-04-27
Abstract: A wood-species domino as a technical means for scientific instruction and artistic design. For this purpose, double chips are formed by bonding together transverse slices of wood of irregular six-sided form and each consisting of two different species of wood, these chips being laid together (domino-style) with the wood species matching. This is done on a frame board which is provided with an adhesive layer so that the pattern formed during the domino game is fixed in its position, as the scientific results of learning, and can simultaneously be used as an artistic relief illustration in the manner of a wall picture. What is new about this means of instruction and design is that the result of a parlour game represents a work of art designed jointly by the participants in the game and that this work of art is not merely observed passively but can be actively modifed or even completely redesigned with the same elements. Another novelty is that the scientific/dendrological instructive and learning content of wood as a material can, by comparative observation instructions for the various structures, become an expert collector's item of universal validity and variety for a wide public.   The wood-species domino is thus conducive to an artistic game with aesthetic/natural elements and to the learning of dendrological features of the wood of trees and shrubs - it is thus environmental of the earth's vegetation and of the immediate neighbourhood. The wood-species domino is also conducive to ... Original abstract incomplete.
