Title: Drive for an adjustable, for example programmable, gripper
Inventor: BURKHARDT FRANK DIPL ING
IPC: B25J15/02
Filed: 1986-01-08
Abstract: In order to set the gripping jaw movement, for example of an IR gripper, in accordance with a program, in order to grip components of different dimensions exactly and to be able to join them in confined conditions, the gripper transmission is driven by a stepping motor. The opening movement of the gripper jaws can be compared with a required value which is stored in the IR controller, by means of an actual value transmitter (for example a variable resistor) which is mounted in or between the gripper jaws. Start/stop and right/left movement commands are transmitted to the stepping motor controller via in each case one output from the IR controller. The high static torque of the stepping motor at rest applies the gripping force. <IMAGE>

Title: Alternative, variable pallet structures
IPC: B65D19/00
Filed: 1986-10-21
Abstract: Multipurpose, variable pallets for goods traffic and storage, which are distinguished in that their loading capacity can be increased by additional supporting elements without any particular specialist knowledge or special tools. Since the carrying surfaces of the supporting parts can, at any time, be removed and stacked in an extremely space-saving manner, such pallet structures constitute a considerable saving in space, in particular when they are to be conveyed or stored empty. In addition, there are the possibilities of long-term use, because all the parts can be exchanged at any time. The pallet carrying surfaces are designed such that they are suitable, if required, for other possible applications, for example for partition-wall structures, for façades or wall parts, for container parts or, in specific cases, as claddings of various types. Such novel pallets can also thus be used for a packaging constituent.

Patent DE-3739554-A1 (DE)
Title: Transformer
Inventor: LUTZ FERDINAND DR ING
IPC: H01F27/245
Filed: 1987-11-21
Abstract: In the case of transformers of known type, the windings must be dielectrically insulated from the transformer core, which is normally at earth potential. The insulation material which is thus introduced between the windings and the core leads to a relatively large winding diameter and, in consequence, to a high requirement for conductor material, and it contributes to a large structural volume of the transformer. In contrast, in the case of the transformer according to the invention, the cost of insulating the windings from the core can be reduced to a minimum, with the advantage of a smaller winding diameter, a reduced requirement for conductor material and insulating material, and hence a smaller transformer volume and transformer weight. The transformer according to the invention has a core which is divided into a plurality of sections which are at different potential. The windings are now arranged around the core such that the mean potential of individual winding sections corresponds approximately to the potential of the associated section of the transformer core. In consequence, the cost of insulating the windings from the transformer core is very low. Transformers for measurement tasks (voltage transformers), for producing high test voltages and for power transmission and for power supply.

Title: Watercraft of lightweight construction
Inventor: SCHUELKE KARL ALBERT DIPL ING
IPC: B63B17/02
Filed: 1988-03-09
Abstract: Sportsboats which are especially stable under way and offer the occupants optimum seating comfort and protection from wind and water are large and heavy. The present invention separates the functions of the supporting hull on the one hand and the protective superstructure on the other hand: the hull is made as flat and as compact as possible; the superstructure only has the task of constituting the protective cockpit. Consequently, the supporting, flat hull cell can be made as strong as necessary in terms of the structure at a light weight, and the superstructure, at a sufficiently large volume, can be made so light that wind and coincidental breaking of waves are just kept away. The principle of the invention is suitable in particular for the design of sportsboats which are also to be transported on a car roof.   <IMAGE>
Patent DE-3808123-A1 (DE)
Title: Process for producing sintered parts of finely particulate metal or ceramic powders
Inventor: POETSCHKE JUERGEN PROF DR ING
IPC: B22F1/052
Filed: 1988-03-11
Abstract: To produce the sintered parts, powders having a particle size of up to 500  mu m and a particle size distribution which approaches the "Fuller distribution" are used. The multicomponent binder added contains at least one component which forms a liquid phase below the melting/softening point of the other component(s) while these solidify to give a sponge-like skeleton having contiguous pores going through (open porosity). The amount of the liquid phase is calculated in such a way that after it is removed by chemical means, there remains in the shaped part a free pore volume matched to the sintering process. The other components are then thermally decomposed, under pulsating superatmospheric pressure above their decomposition temperature and above that temperature at which the powder particles just begin to grow together, in a gas atmosphere whose respective carbon or oxygen activity corresponds to the respective carbon or oxygen activity of the shaped part. Decomposition gases remaining therein are removed by a vacuum treatment, before the shaped part is sintered to closed porosity at temperatures below the flow-point of the material under vacuum and is finally densified isostatically under inert gas.

Title: Method and apparatus for inward flanging
Inventor: RYBINSKI DIETER
IPC: B21D41/04
Filed: 1988-05-28
Abstract: The invention is based on the object of further developing a known method and a known apparatus for the inward flanging of a tube end and for producing a certain diameter of the flange opening in such a way that the flange opening is not produced in the known manner by being punched out because this is associated with high tool wear and unavoidable punching waste. The solution of the object consists in that a flanging head (10) and a needle (12) which is guided axially therein and, in the region of its end, has an encircling groove (14) are driven against clamping jaws (20, 21) holding the tube (16). In the process, the tube end is flanged inwards until it strikes against the narrowest point of the groove (14). The needle (12) is then removed completely, the end region (13) of the needle effecting a calibration of the flange opening (32). A preferred area of application for the invention is with telescopic aerials for vehicles. <IMAGE>
