Title: Clip-on pole terminal for batteries, especially for motor vehicle batteries
Inventor: BIEBER HANS-GUENTER
IPC: H01R11/28
Filed: 1984-02-01
Abstract: In the case of a pole terminal which is used for the connection of a connecting cable to a battery, as an energy store, via a connecting pole, it is proposed to use the pole terminal split, with a rotation point and a compression spring, in the form of pliers. In this case, the construction of the actual clamping body in terms of its shape is maintained, but is split. A fitting connection to the battery pole is made by means of a compression spring instead of a screw. It is possible to release the terminal from the battery pole without tools, by means of a lever which is integrated into one terminal half. The connecting cable to the battery is connected in a fitting manner to the clip-on pole terminal. <IMAGE>

Title: Ski support which can be mounted on the roof of a motor vehicle
Inventor: HUETTLIN HERBERT
IPC: B60R9/12
Filed: 1984-02-01
Abstract: An elongate profiled rod (14) of flexible material is to be attached along a drip moulding (12) on the vehicle roof (10) and has a laterally protruding supporting element (22) against which at least one pair of skis (26) can be leaned. So that it can be attached, the profiled rod (14) has a longitudinally extending recess (20) to accommodate the drip moulding (12) and skirting strips (16, 18) arranged on both sides of the latter. Owing to the structure of the material of which it is made and/or its shape, the profiled rod prevents the skis leaning against it from sliding to the side and therefore falling off. Owing to the lateral projection of its supporting element, the profiled rod also protects the drip moulding against damage to the enamel. <IMAGE>

Title: Heating plate for a press
Inventor: OTT ROLAND
IPC: B29C35/00
Filed: 1984-03-09
Abstract: A heating plate (1) is connected to a feed line (5) and a return line (6) which lines can be part of the supply and return system, for example of a hot-water heating system of a building, in particular of the factory building in which a press having the heating plate or such heating plates is installed. The heating plate (1) can thus be heated maximally to the supply temperature in the feed line (5) of the heating system. If a higher temperature of the heating plate (1) is required, the first valve (7) in the feed line (5) and the second valve (8) in the return line (6) are closed. Via a connecting line (13), a so-called "small circuit" for the liquid heating medium, which is now shut off, is provided. The heating medium is circulated with the aid of a pump (12) and heated further via a heating device (15). If appropriate, the closing of the valves (7, 8) and the switching on of the, in particular electric, heating device (15) can be controlled via a thermostat (10) with a sensor (9). The heating medium can also be heated exclusively by the heating device (15). <IMAGE>
Patent DE-3410465-A1 (DE)
Title: Method and device for determining the boiling of liquids and/or foods
Inventor: SEYER REINHARD DIPL ING
IPC: A47J27/62
Filed: 1984-03-22
Abstract: The invention relates to a method for determining the boiling of liquids and/or foods. A signal is required for the beginning of the boiling of a liquid or an object to be cooked located in a container, which signal can be used to control the energy supply so that the boiling can be interrupted or just maintained. According to the invention, the boiling movement of the liquid or the object to be cooked is recorded and a signal is derived therefrom. The recording can take place by means of ultrasonic Doppler radar; ultrasound at a fixed frequency is radiated into the object and the radiation reflected from the object is received. During boiling, the frequency of the reflected radiation changes in relation to the frequency of the incoming radiation; a signal is derived from the change in frequency. <IMAGE>

Title: Metal-encapsulated, gas-insulated switching installation
Inventor: GUTALJ VLADIMIR
IPC: H02B13/035
Filed: 1984-04-16
Abstract: The single-conductor current transformers (8, 9, 10) which are accommodated in the encapsulation (2) of the switching installation (1) are arranged offset with respect to one another by at least their length (L) in the longitudinal direction of the current conductors (5, 6, 7). This allows the current conductors (5, 6, 7) together with the current transformers (8, 9, 10) to draw together in a direction running transversely with respect to the current conductors (5, 6, 7), as far as the minimum necessary insulation separation. This allows the cross-sectional dimension of the encapsulation (2) to be correspondingly reduced. Undesirable influencing of the current transformers (8, 9, 10), which are now located closer to the current conductors (5, 6, 7) is prevented by means of a screen (13), which is in the form of a sleeve and surrounds the current transformer core (11) together with the secondary winding. Said screen (13) consists entirely of partially of a ferromagnetic material and is preferably constructed from a plurality of layers (14, 15). A screen (13) consisting of a material which is not ferromagnetic but is electrically conductive is likewise possible. <IMAGE>

Patent DE-3445105-A1 (DE)
Title: Gas turbine
Inventor: HOELSCHER ANTON
IPC: F02C5/12
Filed: 1984-12-11
Abstract: A gas turbine with open cycle and power output in the form of shaft power, a compressor arrangement, combustion chambers briefly enclosed all round and a blade arrangement connected, so as to be fixed in terms of rotation, to the shaft has, alternating in the direction of rotation, larger and smaller outlet apertures of the compressor chambers. Combustion chambers, roughly in the form of an inclined "U", are arranged distributed over the circumference, the leg ends of which form combustion chamber entrances. Rotatably arranged piston elements, which adjoin the respective outlet apertures and are so designed that the combustion chamber entrances can be tightly sealed, are distributed over the circumference. The outlet apertures are arranged so that a larger outlet aperture initially produces an outflow of the hot gas and both outlet apertures then open simultaneously into the leg ends of the combustion chambers, as a result of which opposing flows are produced which lead to an increase in pressure compared to the compressor pressure.
