Inventor: LANGNER BERND DR
IPC: G01N27/416
Filed: 1987-06-03
Abstract: The effectiveness of organic additives acting as inhibitors during the electrolytic deposition of metals from aqueous electrolytes, which contain organic additives for improving the deposition of metal, is electrically measured. In order to permit an improved and more reliable check of the effectiveness of the inhibitor and to permit a controlled supply of makeup inhibitors at the required rate, a partial stream of the electrolyte is supplied to flow at a constant velocity in a measuring cell provided with at least three wire electrodes having a fresh conductor surface, a measuring current of 5 mA to 1.0 A is supplied to the electrodes and is maintained, and the slope of the plotted cathode potential-time curve in the range from 0.1 to 50 minutes is taken as a measure of the effective conecentration of the inhibitor. The method can be used to measure the effective inhibitor concentration in an electrolyte used to electrorefine copper and to measure the effective conecentration of brightener in the electrodeposition of metal.

Title: Control device for a motor vehicle automatic gearbox
Inventor: OBERPICHLER GERD DIPL ING
IPC: F16H61/12
Filed: 1987-09-03
Abstract: A control device for a motor vehicle automatic gearbox is described, which has a main pressure control valve (1) for developing a main pressure as a function of the operating state for the actuation of shift elements of the gearbox and a solenoid control valve (2), which generates a control pressure, varying at least as a function of the load condition of the engine assigned to the motor vehicle, for acting on an active surface (6a) of the control piston (3) of the main pressure control valve (1). At the same time, the solenoid control valve (2) is designed to generate a control pressure increasing proportional to the load of the engine and the control pressure acts on an active surface (6a) of the control piston (3) of the main pressure control valve (1), loaded by the spring (11), against the main pressure acting on at least one counter-surface (6b; 7a). In order to be able to use a solenoid control valve of the simplest possible design and at the same time to be able to generate a sufficiently high main pressure by means of the main pressure control valve (1) in the event of a breakdown, that is should the solenoid control valve fail, it is proposed that a switch valve (15) be connected to the main pressure control valve on the inlet side, which switch valve ... a pressure admission space (12), assigned to the active surface (6a) of the control piston (3) of the main pressure control valve (1), to the control valve in a first position, with the control valve (2) operating, ...

Patent DE-3734147-A1 (DE)
IPC: A61K31/23
Filed: 1987-10-09
Abstract: Conventional isotonic lipid emulsions containing essential  omega -3-fatty acids, e.g. in the form of EPA, can be converted only inadequately in vivo into triunsaturated eicosanoids because they are preferentially consumed in energy metabolism, i.e. oxidised. Combination of  omega -3-fatty acids or their physiologically acceptable esters with triglycerides of medium chain length results in the triglycerides of medium chain length being preferentially oxidised in the body, and the  omega -3-fatty acids being protected from rapid oxidation so that increased amounts of them are available for the formation of triunsaturated eicosanoids. The combination also has a protective effect on the liver. Isotonic lipid emulsions containing  omega -3-fatty acids are used, in particular, for parenteral administration in post-aggression metabolism associated with chronic inflammatory disorders and in neonatology and paediatrics.

Title: Method and device for improving the intelligibility of voice in communications devices
Inventor: GENUIT KLAUS DR
IPC: H04R5/033
Filed: 1987-11-07
Abstract: In a method and a device for improving the intelligibility of voice in communications devices, namely especially in the case of headsets with microphone and headphones in an environment filled with interfering sound, it is proposed to equalise the headphone signals in such a manner that a directional impression outside the medial plane and outside the head of the listening person is produced so that the binaural signal processing in the human ear can be utilised. In addition, the spectrum of the reproduced signals is equalised with the aid of filters in such a manner that only the spectral components masked by the interfering noise are amplified, and the delay times existing in the filters for the direction coding are changed by adding a basic delay time in such a manner that voice control is possible without suppressing the initial syllable.

Title: Device for transporting elongated objects, especially skis, in a car
Inventor: TRUTTER WALTER-PAUL
IPC: B60R5/00
Filed: 1987-11-17
Abstract: A device for transporting elongated objects, especially skis, in a car, has a dismountable elongated container, which can be loaded with the object to be transported from the boot via a through-loading aperture provided between the boot and the passenger compartment. The container stretches from the through-loading aperture forwards into the passenger compartment. A ski bag is used as a container and its cover is connected at its circumference to the inside surfaces of a frame-like receptacle, in which the ski bag can be stowed away when not in use. The frame-like receptacle itself can be releasably fastened in the region of the through-loading aperture to the body parts which act as a support for the rear seat back rest. A transporting device of this type can advantageously be accommodated as an accessory in the space behind a rear seat back rest, which may be divided. The transporting device is easy to mount and dismount. When the transporting device is not required, it can be easily dismounted from the vehicle. In the mounted condition, the transporting device does not in any way limit the amount of space available in the passenger compartment and/or in the boot of the vehicle.

Title: Drive extension/retraction mechanism for 2-engined aircraft in weight classes (civil) G, I, K and corresponding military aircraft
Inventor: KLOTZ WILLI DIPL ING
IPC: B64D27/00
Filed: 1987-12-10
Abstract: The invention relates to 2-engined aircraft, such as those for which a patent was applied for by the applicant in 1977, for shrouded fan engines. The present invention relates to the use of engines having free propellers, which automatically fold up after the engines have been stopped. The propeller engines, when unfolded, are located in the triangle between the fuselage and wings (low-wing monoplane) and thus project less from the aircraft structure than in the case of known retractable engines. In the retracted state, the engines with the propeller are located - without any detrimental aerodynamic effect - in the fuselage, which allows economical gliding. The engines can be extended/retracted independently of one another. Slow cruising flight is thus also possible, using only one engine. The retraction mechanism is simple. Motor-driven or hand-driven spindles act on the so-called pylons whose rotation points are arranged close to the wing root. In the extended state, the force-fitting cups in the region of the fuselage outer wall increase the static strength of the engine mounting.

Title: Shock wave generator for contactless destruction of concrements, and method for producing it
Inventor: HOFMANN GEORG ING GRAD
IPC: G10K9/12
Filed: 1987-12-15
Abstract: The invention relates to a shock wave generator for a device for contactless destruction of concrements in the body of a living creature. The shock wave generator has a flat coil (4) which can be connected to a high-voltage supply, and a diaphragm (3) which is situated opposite said flat coil, encloses liquid volume (2) and is made from an electrically conductive material. At its rear, which faces the flat coil (4), the diaphragm (3) is subjected to a pressure which is lower than the ambient pressure, with the result that the diaphragm (3) is pressed against the flat coil (4) owing to the pressure difference. It is provided in this case that the space located between the rear of the diaphragm (3) and the flat coil (4) is hermetically sealed, and that the pressure which is lower than the ambient pressure prevails in said space. <IMAGE>

Title: Coloured fingering notes
Inventor: STAMMLER GUDRUN DAGMAR
IPC: G09B15/02
Filed: 1988-01-07
Abstract: My invention "coloured fingering notes" is an instrumental/pedagogic system which serves considerably to facilitate the learning of musical instrument playing. This takes place by the information about the fingering being integrated into the note head, and in particular by colouring. In my system, each finger is assigned a colour, and each note head bears the colour which corresponds to the finger to be used. The "coloured fingering notes" system cannot only be used for all keyboard instruments but also for stringed instruments such as harps and zithers, for all bowed string instruments as well as for the fingerboards of guitars and related plucked instruments and also for woodwind instruments. A modified use is also possible for percussion instruments. A prerequisite for the spreading of the system is note printing in colour.

Title: Method for threading an optical fibre
Inventor: KROPP JOERG-REINHARDT DR RER N
IPC: G02B6/44
Filed: 1988-07-12
Abstract: Since, when optical waveguides are prepared using plug pins, the optical waveguide ends have to be inserted exactly into a central hole in a plug pin, and since the diameter of the holes inside the plug pins is only slightly larger than the outer diameter of the optical waveguide ends, it is necessary to create a method for threading optical waveguide ends into narrow holes. The object is solved according to the invention in that while threading an optical waveguide (5) into a plug pin (1), the plug pin is rotated around its longitudinal axis. The optical waveguide creeps along the inside wall of the insertion funnel (6) in the plug pin and finds its way into the centre hole (4) inside the plug pin. The invention is used in the area of preparing optical waveguides. <IMAGE>

Patent DE-3832135-A1 (DE)
Title: Compression adjustment in unilaterally acting axial flow rotary engines
IPC: F02B75/02
Filed: 1988-09-22
Abstract: In the cylinders (3) rotating with the engine shaft (1), the pistons (4) are guided by means of rollers (5) on the lifting cam (6) so that they follow the path of the four-lift line of symmetry (14), in the process rotating axially up and down on the static engine housing (11). The compression can be adjusted both mechanically and hydraulically. In both cases the lifting cam (6), radially fixed by the guide pins (9), is moved more or less towards the cylinder cover (2) against the force of disc springs (10), thereby simultaneously increasing the compression of all pistons (4) by the same value as a function of control data, possibly by way of knocking sensors. An adjustment of the lifting cam (6) away from the cylinder cover (2), on the other hand, reduces the compression on all pistons (4) by the same value. The hydraulic adjustment of the lifting cam (6) is dependent on the level of the pressure, which acts in the annular space (8) by way of the line (7), thereby moving the lifting cam (6) towards the cylinder cover (2) against the force of the disc springs (10) or away from it as the pressure subsides. Mechanical adjustment of the lifting cam (6) is produced by a corresponding rotation on the worm (13), which in turn causes a rotation of the ring nut (12) on the thread of the lifting cam (6), as a result of which the latter moves axially towards the cylinder cover (2) or ...
