Title: Brine resting cabin
Inventor: BROKMEIER KARL-HEINZ DR ING
IPC: A61M21/00
Filed: 1986-12-13
Abstract: Health basins or brine resting cabins - as floatbox, Samadhi tanks and the like - have been known for a long time all over the world. When used privately they are meant for relaxation and stress relief and when used commercially they serve the same use or are applied for medical therapy under instruction from physicians. The bather floats on salt water, kept at 34.5@C, in the absence of light, sound or heat flux for about 60 minutes and is thereby relaxed and relieved of stress. The previous designs do meet the hygienic requirements for commercial applications and the hygiene required in private use in Germany. By a suitable arrangement of a bath basin, a clean water room, a consumer water room and a storage room in a favourable design form the invention creates the prerequisites for cleaning the basin before each bathing process and continuous cleaning during the 60 minutes of use.

Patent DE-3643509-A1 (DE)
Inventor: MARKER HANNES
IPC: B63B35/79
Filed: 1986-12-19
Abstract: The device has a sleeve (7) which is permanently fixed to the mast (8) and is located in a lightly clamping position enabling the height to be adjusted. The sleeve is provided with a clamping element which, when pivoting the forked boom from an acute-angle or roughly parallel position in relation to the mast (8) into an operating position perpendicular to said mast, is clamped in such a manner that the sleeve (7) is in an immovable clamping position. The height of connection of the forked boom can thus be easily and rapidly modified, whereby at the same time immovable securing of the forked boom is ensured.

Title: Device for supplying power to an electronic signal processing stage
Inventor: SPIES HANS
IPC: G01S7/486
Filed: 1987-06-13
Abstract: The invention relates to a device (8) for supplying power to an electronic signal processing stage (7). Such signal processing stages are used in active and passive sensors such as pulse-operated separation sensors or video receivers. In order to reduce the power consumption of the signal processing stage, it is proposed according to the invention that the device (8) for supplying power be connected in a controlled manner essentially only when signals to be processed are present. As a result of this measure, even signal processing stages having complex signal processing can be supplied with a small amount of power, which can be applied, for example, by a battery. <IMAGE>

Patent DE-3743899-A1 (DE)
Title: Rail brake magnet
Inventor: SKACH KUNO DIPL ING
IPC: B61H7/08
Filed: 1987-12-23
Abstract: The rail brake magnet has at least one magnet yoke (1) which is provided with pole shoes (4, 5) on its underneath. One of these pole shoes (4) consists, as does the magnet yoke (1), of a material having high magnetic permeability, while the other pole shoe (5) consists, at least in the region of its sole (8), of a spheroidal graphite iron material. Different arrangements of the soles (8 and 7), which consist of the spheroidal graphite iron material and of the material having high magnetic permeability, are possible on the rail brake magnet. The rail brake magnet has a high magnetic flux which is virtually uninfluenced by the spherical graphite iron material and avoids producing wear like swarf. The formation of bridges, caused by swarf and/or smearing, between the pole shoes of different polarity is thus avoided, and in consequence a magnetic short-circuit between the pole shoes is avoided. <IMAGE>
Patent DE-3800484-A1 (DE)
Title: Dual, rechargeable electric battery
Inventor: SCHULTEN RUDOLF PROF DR
IPC: H01M8/1004
Filed: 1988-01-11
Abstract: The invention relates to an electric battery comprising stacked sheets. The first type of sheet is proton-conductive and covered on both sides with electroconductive layers which at the same time catalytically ensure the transition of the protons into chemically bound compounds of hydrogen. The two other types of sheets are porous spacers which each serve as feeders for the hydrogen carriers and the combustion air and as auxiliary conductors for output and input of the electric current. The object of the invention is to implement, on the basis of battery and fuel-cell technology, a method which combines an energy store and a power generator, which can be recharged both by feeding in electricity, with the aid of the electrolysis of water, and by replacing the hydrogen carrier. Conversely, the proton-conductive sheets are able, by catalytic oxidation of the hydrogen carrier with air, to generate electric current. <IMAGE>

Title: Medical forceps, in particular arthroscopy forceps
IPC: A61B17/28
Filed: 1988-01-29
Abstract: The invention relates to a medical forceps, in particular arthroscopy forceps, in which the forceps shaft is tubular and carries at least one articulated bit member at the end near the patient. The bit member can be actuated by pressure or tension by means of a rod inside a forceps shaft and the rod is in articulated connection with a movable handle part on the end remote from the patient, the forceps shaft being rigidly connected to a fixed handle part. In order to improve this forceps in such a way that the forceps handle can be used for a wide variety of purposes it is proposed by the invention that an articulated adapter piece be arranged between the movable handle part and the rod, the adapter piece reversing the direction of operation of the rod. In order to increase the manual force considerably, if and when required, it is provided, inter alia, that the movable handle part be provided with a slot which is eccentric relative to the fixed axis for receiving a pin of the articulated adapter piece, this eccentric slot having an outward curve for reinforcement of the manual force.

Title: Method for determining the forces and length changes of individual threads occurring in response to uniaxial tensile stress
Inventor: FISCHER DETLEF
IPC: G01N3/04
Filed: 1988-08-29
Abstract: The invention relates to a method for determining the forces and length changes of individual threads, especially of hairs, occurring in response to a uniaxial tensile stress. So that the method can be carried out very much quicker it is proposed that the individual threads be connected to one another to form a continuous thread and the force values and stretch values of the individual threads then be determined by means of a fibre-tension tester allowing the automatic introduction of new thread portions of the continuous thread into the test stage. The invention relates, furthermore, to a device for connecting individual threads, especially hairs, to form a continuous thread. In order to achieve a rapid and simple connection of the individual threads, it is proposed that a holding block having at least one groove, which possesses at least one air-intake hole connectable to a vacuum pump, be provided in the device. <IMAGE>

Patent DE-3832054-A1 (DE)
Title: Electromagnetic control valve
Inventor: FROHBERG GUENTHER
IPC: F16K31/06
Filed: 1988-09-21
Abstract: Known control valves tend to exhibit natural vibrations and thus tend to distort the required pressure characteristic. This disadvantage is avoided with the novel control valve. The novel control valve is distinguished by the fact that vibrations of the armature are dampened by a damping plate in an oil space. Electromagnetic control valves of this type are used in the control of automatic transmissions, e.g. in motor-vehicle construction.

Patent DE-3839297-A1 (DE)
Inventor: EBNER ARNO
IPC: B65H5/10
Filed: 1988-11-21
Abstract: A driving and control unit for producing forward and return movements of a transport picker (24) comprises a motor-driven crank disk (29) with a slotted link (35) in which a crank pin (37) of a coupling element (39) of a four-bar linkage is guided for radial movement. During one revolution of crank disk (29), the coupling element (39) and a further control lever (67) influenced by crank disk (29) cause the transport picker (24) via a coupling mechanism (59) to carry out an opening and closing movement respectively as well as a forward and return movement in addition to a functionally correct positioning of the claw (55, 56) with respect to the clamping and release positioning of transport picker (24) and a functionally correct path of movement thereof. The crank disk (29) is designed such that it controls during its rotation the temporary arresting of the pivotal movement of the transport picker (24) while continuing at the same time to carry out further control functions, such as the opening of the picker claw (55, 56).
