Patent DE-3616477-A1 (DE)
Title: Shoe stretcher
Inventor: HUBMAYR DIETER ING
IPC: A43D3/14
Filed: 1986-05-17
Abstract: For shoe stretchers with one-piece shaped bodies which are flexible in sections, the task exists of achieving, with simple handling and shaping as well as manufacturability, function-matched tension forces and tension-force distributions in the longitudinal and transverse directions. As a solution, the shaped body has a central section (3) of, in relation to a heel-side and toe-side end section (1 and 3 respectively), a greater springy elastic flexibility in relation to bending axes extending transversely to the stretching direction (X-X) and parallel to the width direction of the shaped body. Advantageously, the central section (3) is designed in the manner of a leaf spring and with a flat rectangular cross-section. The concentration thus achieved of the flexibility of the shaped body in its central section makes possible convenient handling with optimum adjustability of the longitudinal tension pressure as well as with a simple shaping technique which favours manufacturing. <IMAGE>

Patent DE-3642108-A1 (DE)
Title: Switching installation for distributing electrical power, and a method for operating the switching installation
Inventor: LUTZ FERDINAND DR ING
IPC: H02B1/24
Filed: 1986-12-10
Abstract: This medium-voltage or high-voltage switching installation has a main busbar (3) and two auxiliary busbars (1, 2). Each auxiliary busbar (1, 2) is connected to the main busbar (3) via a power switch (circuit breaker) or load-interrupter switch (LS1, LS2). The supply line or lines (4) and the outlet lines (5, 6) are in each case connected to all three busbars (1, 2, 3) via interrupter switches (T01, T02, T03, T11, T12, T13, T21, T22, T23). If the current flow (load current or short-circuit current) in one of the supply or outlet lines is intended to be interrupted, this line is initially commutated without interruption onto an auxiliary busbar and the interrupter connection of this line to the main busbar is then interrupted. The current flow through the power switch or load-interrupter switch associated with this auxiliary busbar is subsequently interrupted. The current flow in all the other lines is not influenced by this process. A line is switched on in a similar manner, likewise by commutating onto an auxiliary busbar. If, independently of this, it is necessary to connect or disconnect a further current to or from another line at the same time, the first line to be connected is connected to one auxiliary busbar, and the second circuit to the other auxiliary busbar. <IMAGE>

Patent DE-3808878-A1 (DE)
Title: Skis with special features
Inventor: BACKHAUSS ROLF
IPC: A63C5/16
Filed: 1988-03-17
Abstract: The skis referred to in the patent application and in the description are an absolute novelty. The novelty is based on observation of skiers, whose skis pass over the partly iced piste with unpleasant vibrations in an oblique position and have to accept running-out at a gate. Or let us consider cross-country skiers moving uphill. What a laborious technique is expected from the participant in order to achieve this. The answer to this is in the patent application and the description, for let us consider for example a vehicle tyre without tread for normal road traffic. It has always been an absurdity and will remain so. The advantages of the ski with a separated running surface are obvious. The disadvantage is the cost question and the weight of the individual ski. Thus, this ski is not designed for the beginner. Development still lies in the future. This ski has improved steering in bends and improved springing. It is also very suitable for cross-country skiing.

Title: Roadway support machine with combined drilling and support-setting apparatus
IPC: E21B7/02
Filed: 1988-05-27
Abstract: A roadway support machine provided for the mechanised driving of roadways in underground mining and tunnelling has a short overall form despite the integration of a drilling device, so that it can be readily manipulated and can also be used in unfavourable curved roadways. The working platform and the drilling device are arranged in a liftable and lowerable manner on the heavy-duty beam via separate parallel booms or parallelogram booms. The carriage of the drilling device additionally has receptacles for the roadway support arches. Attached to the tip of the parallelogram boom is a swivelling mechanism via which the carriage can be swivelled by 360@. The parallelogram boom itself is linked to a slewing ring which is part of the heavy-duty beam so that the entire parallelogram boom with the carriage arranged on it can be swivelled via corresponding cylinders. In addition, the parallelogram boom is of two-piece design, working cylinders being allocated to each of the sections so that both sections pivotably connected to one another via a bracket can be adjusted separately or in a corresponding manner. Finally, the carriage itself is also made of two sections, the front section being hinged so that the carriage length required for the drilling device can be obtained without the range of use of the support-setting traverse being affected. <IMAGE>
