Patent DE-3531990-A1 (DE)
Title: Marine propulsion system
Inventor: SCHMID HEINRICH
IPC: F02D29/02
Filed: 1985-09-07
Abstract: Provided as propelling engine (3) for a passenger ship is a slow-speed diesel engine which is directly coupled to the propeller shaft (1), which is provided with a controllable-pitch propeller (2).   The propelling engine (3) is designed in such a way that it covers the propulsive output for the maximum cruising speed required. For the power requirement exceeding this in order to obtain full speed, an electric motor/generator (7) is provided in series with the engine (3). The motor/generator (7) is supplied from the power reserve of the ship's electrical system (4). The electric energy is produced by several medium-speed or high-speed four-stroke engines (6). In terms of power output the four-stroke engines (6) are designed in such a way that there is a considerable excess of power capacity compared with the demand in the ship's electrical system (4). The installed engine power is better utilized by the novel propulsion system than in systems in which the propelling engine (3) is designed for the power requirement at full speed. <IMAGE>

Title: Circuit for a thin-film magnetic head
Inventor: EZAKI JOICHIRO
IPC: G11B15/12
Filed: 1985-12-27
Abstract: Circuit for a thin-film magnetic head (1) without centre tap for magnetic recording purposes, having a read amplifier (2) and a pair of mutually parallel, earthed matching resistors (R1, R2), connected to the amplifier (2), which circuit has been improved by a third pair of switching transistors (9, 10) being arranged parallel to the matching resistors (R1, R2) in order to short-circuit the latter. In the write operating phase, a current flows through the coil (S) of the magnetic head (1) whenever one transistor of a pair of switching transistors (4, 5) has been made conductive in a way corresponding to a write signal ("0" or "1"), and one of the switching transistors (9, 10) is connected to the coil (S) of the magnetic head (1) in a way corresponding to the polarity of the direct-current potential, so that the non-active current, which does not flow through the coil (S) but through the switching transistors (4, 5), is significantly reduced. On account of the reduction of the non-active current in the switching transistors (4, 5), the operating speed of the circuit is increased. <IMAGE>

Title: Computer system with several computers
Inventor: BAUER JUERGEN
IPC: G06F15/16
Filed: 1986-02-20
Abstract: A computer system with several computers is proposed, and in it data transmission between the computers is monitored in such a way that in each case a predefined amount of data to be transmitted is combined into one data block. The data is then transmitted serially from the sending computer to the receiving computer, where the amount of data received is compared with the predefined amount. The data blocks are also transmitted cyclically at predefined time intervals, so that as well as the amount of transmitted data, a bit which identifies the start of the data block can be tested. The proposed testing of the data transmission can be implemented simply, and yet represents a very thorough test of correct functioning of the data transmission and the sending computer. <IMAGE>

Title: Device for measuring the radial play of antifriction (rolling) bearings
Inventor: BLUM EDGAR
IPC: G01M13/04
Filed: 1986-07-16
Abstract: A device for measuring the radial play of antifriction bearings, the measured value is determined directly between the surface of the bore of the inner ring and the circumferential surface of the outer ring. In this case, both the outer ring and the inner ring rotate. As a result, the measurement result is not affected by untrue running of the drives and tolerance-induced errors in the individual parts. Due the preferably axial clamping of the antifriction bearing between the drive madrel and an axial bearing, the ball surface of the inner ring is largely free for mounting a probe.

Filed: 1986-09-12
Abstract: The invention deals with a method of operating winning machines used in underground mining, in particular shearer loaders or selective-cut heading machines, the operating or status data of which are continuously recorded and fed to a computer for analysis. This computer is either arranged directly on the machine to be monitored or is accommodated in the control station of the roadway or in the operating station at the surface. From the data reaching it, the computer determines by means of a diagnosis system the machine faults and if need be also their causes, indicates faults and causes on a display and retains them in a memory. According to the invention, the computer is now to evaluate the fault and the causes of the fault and decide whether the winning machine or the selective-cut heading machine can continue to be used at least for a certain time interval and if need be introduce measures for rectifying the fault or its causes or else reduce the effects of such faults. During the time in which the faulty machine continues to be operated after evaluation by the computer, the faults detected and/or their causes remain non-erasable in the memory and are indicated on the display in order to constantly point out their rectification to the operator.

Patent DE-3709382-A1 (DE)
Title: Method for forming the switching-on signals for the semiconductor switches of an invertor
Inventor: ROLLE SVEN
IPC: H02M7/538
Filed: 1987-03-21
Abstract: In the case of a method for forming the switching-on signals for the semiconductor switches of a self-commutated invertor which impresses a voltage, in the case of which a diode is connected in reverse parallel with each semiconductor switch and/or in the case of which the switches conduct in reverse, it is intended to achieve a short switching sequence. This is achieved in that, with respect to one invertor branch in each case, the first switch (S+) (which is connected between the output terminal and the positive pole of the DC voltage source) is closed in order to increase the current when the required value of the output current is positive and is opened to reduce the current, while the second switch (S-) (which is connected between the output terminal and the negative pole of the DC voltage source) remains open, and in that the second switch (S-) (which is connected between the output terminal and the negative pole of the DC voltage source) is closed in order further to reduce the negative current (increase the absolute value of the current) when the required value of the output current is negative and is opened in order to increase the current (reduce the absolute value), while the first switch (S+) (which is connected between the output terminal and the positive pole of the DC voltage source) remains open. <IMAGE>

Abstract: The sauna heater has, in a side wall, a thin shaft (35) extending over a part of the width of the side wall. This shaft has approximately the thickness of the conventional insulation. In the area of its lower end, a fan (40) is provided. This is allocated an adjustment slide (55.1 to 55.3) which determines the cross-sections of the air inlet openings and thus the proportions of the air to be reheated (54.2) and fresh air (54.1). At the upper end (68) there is a deflection arrangement (70), which conveys the air forced up by the fan (40) into the heating arrangement. Electrically heated heat registers (81) are provided there. These are provided with aerated sheet-metal coverings, through which there flow currents of cool air diverted from the cold air current. The air heated in the heat registers and the cool air together pass through a suitably shaped flat distribution nozzle (85) directly under the ceiling of the sauna cabin and flow out slowly and equally noiselessly. <IMAGE>

Patent DE-3725922-A1 (DE)
Title: Method and arrangement for detecting even rapid electrical processes
Inventor: GAST JENS-PETER DIPL ING
IPC: G01R19/25
Filed: 1987-07-31
Abstract: The invention relates to a method for detecting even rapid electrical, possibly cyclically occurring, commutation or equalisation processes which influence computer-aided controllers or regulators and in the case of which the control or regulation variables are digitised by means of an analog/digital converter, especially for converters and controllers. In this case, processes, for example commutation and equalisation processes, as occur cyclically for the most part after a switching operation and are of importance for the assessment of the serviceability of the system in the next switching cycles are detected, despite their time duration of a few microseconds and different types of complex time responses. This is achieved according to the invention in that a voltage which is proportional to the measurements from the commutation or equalisation processes is tracked to its limit value and this value is then stored, in that the stored limit value is digitised by the A/D converter (1) in a time gap which is not loaded by the controller or regulator and is available for influencing, and in that, immediately after the conversion and reading into the computer (3), the last limit value is erased for possible storage of a subsequent event. <IMAGE>

Title: Bottle closure
Inventor: VEDDER JOSEF
IPC: B65D41/34
Filed: 1987-08-21
Abstract: Arranged below a plastic screw cap is a securing ring (22) which is connected to the cap by tear-off webs (18, 19, 20) and a holding web (21). Projecting inwards from the securing ring (22) are holding projections (23) which engage below the bottle bead. The intended tearing point (25) is located opposite the holding web (21). The holding projections (23) are circumferentially offset relative to the intended tearing point (25). When the cap is unscrewed, the tear-off webs (19, 20) in the central region between the holding web (21) and the intended tearing point (25) tear first. The securing ring (22) thus forms two loops which hang down. During continued unscrewing, the tear-off webs (18), arranged in the immediate vicinity of the intended tearing point (25), tear, the intended tearing point being torn open from the top to the bottom. <IMAGE>
