Title: Wiper device for windows of motor vehicles
Inventor: KUEHBAUCH GERD DIPL ING
IPC: B60S1/24
Filed: 1987-11-12
Abstract: A device is proposed which serves for wiping windows on motor vehicles. The wiper device comprises a driving assembly with a rotating output motion and an oscillating gear mechanism which is subordinate to the latter, is designed as a linkage and has at least one output shaft which supports a wiper and forms the wiper shaft, and the housing parts are connected to one another in each case via a hinge which has a pin which is attached to one linkage part and is mounted in a pin bearing of the other linkage part. At the same time, for the adjustment of the effective length of the linkage part, the hinge pin is provided with a guideway which is arranged eccentrically relative to the bearing axis of said pin, at least partially surrounds the bearing axis and cooperates with a counter-guide on the housing part which supports the bearing pin. So that a uniform bearing-pin adjustment is assigned over the entire possible bearing-pin adjustment path of a certain change in the angle of rotation of the bearing pin, the guideway is formed by a segment of an Archimedes' spiral. <IMAGE>

Title: Electric motor, especially a small electric motor (miniature electric motor)
Inventor: BRUHN RAINER
IPC: F16H57/021
Filed: 1987-12-24
Abstract: The invention relates to an electric motor, especially a small electric motor, which has a housing, a motor shaft (which is mounted in the housing such that it can rotate) and a checking part for setting the axial play of the motor shaft. The checking part can be displaced in the longitudinal direction of the motor shaft and is acted on by a spring in the sense of reducing the axial play. A capability for setting the axial play of the motor shaft is obtained in a simple manner and without significantly reducing the efficiency of the electric motor, by the checking part being the locking piece of a fixed locking mechanism which acts on one side. The locking element of such a fixed locking mechanism can be displaced in one direction, while any movement in the other direction is impossible.
Patent DE-3744511-A1 (DE)
Title: Method for controlled distribution in the spectral band of electromagnetic and/or acoustic energy which passes through and/or is reflected from a body of any shape, in order to make detectability more difficult, and for indirect reduction of the echo cross-section
Inventor: SEDLMEYER AXEL DR ING
IPC: F41H3/00
Filed: 1987-12-30
Abstract: A method to make the detectability of bodies more difficult which emit their own electromagnetic and/or acoustic energy or reflect any such incident radiation. The emitted energy from (military) objects is at present reduced by shaping and absorbent materials. This constrains the design capabilities and increases the production costs. In addition, these measures are not sufficiently effective in the electromagnetic band from 12 MHz to 500 MHz. The new method, in contrast, is not intended to necessitate any design constraints, and is intended to be effective over the entire frequency band. A distribution of the emitted (reflected) energy over wide bands of the spectrum is achieved with the aid of modulators on the surface of the objects and additional controllable (auxiliary) radiation sources. In consequence, the energy of the originally radiating (echoing) frequency is greatly attenuated. By changing and selecting the frequency of the auxiliary radiation sources quickly in time, it is made extremely difficult for a receiver external to the system to receive the modulation products for location of the object. Reduction in the location capability in the electromagnet and/or acoustic band of radiating and reflecting objects.
Patent DE-3803643-A1 (DE)
Title: Safety device for motor vehicles
Inventor: WAGNER CHRISTIAN
IPC: B60R7/06
Filed: 1988-02-06
Abstract: A safety device (1) for motor vehicles is described which takes up the forces produced by collision of a knee against a glove compartment. To achieve this, a transverse support (7) is arranged at the same height as a knee impact element (3) and is therefore loaded without torsion. In addition, the side cheeks of the glove compartment form intermediate elements (2a) for the transmission of force from the knee impact element (3) to the transverse support (7). The latter can be fixed so as to be free to a substantial extent in its position in the longitudinal direction of the vehicle by being fixedly bound to a bow (5) which is horizontally banked. The deformation behaviour of the safety device (1) can be specifically influenced by the length of the intermediate elements (2a). <IMAGE>

Title: Machine for producing rollmops
Inventor: HEHER HANS-JUERGEN
IPC: A22C25/22
Filed: 1988-03-15
Abstract: The invention relates to a machine for producing rollmops which winds a fillet of fish into a complete rollmop in such a way that the winding machine has four driven and movable cylindrical rollers which are arranged with axes which are parallel to one another and can be moved towards and/or away from one another, depending on the diameter of the material to be wound which is in the winding stage. The invention results in the following advantages for producers of rollmops: The rollmops are no longer wound by hand, but by the machine. Mechanical production of the rollmops, which is completed in a matter of seconds, leads to a considerable increase in output. It is possible to produce about 40 rollmops in a minute. The advantages achieved by means of the invention are in particular that production costs are lowered and the rollmop can be rolled more evenly and cleanly.

Patent DE-3816590-A1 (DE)
Title: Device for triggering a passive safety device
Inventor: WOEHRL ALFONS
IPC: B60R21/01
Filed: 1988-05-16
Abstract: The invention relates to a device for triggering a passive safety device (1) which is installed in a vehicle and is triggered in the event of an impact. For this purpose, the output signals of an acceleration sensor (2a, 2b) are fed to an evaluation circuit (4a, 5a, 4b, 5b), after which the evaluated signals are passed onto a triggering circuit (6) for the safety device. In order to be able to distinguish reliably an actual impact of the vehicle from other situations in which high mechanical stresses act briefly on the acceleration sensor, without however these stresses being able to put the occupant of a vehicle at risk, it is proposed according to the invention to provide a rating circuit (A, B, C) which initially blocks the enabling of the safety device (1) for a brief time with the aid of a timing circuit (B) when a significant output signal occurs and only enables the said safety device (1) subsequently. <IMAGE>

Patent DE-3823913-A1 (DE)
Inventor: KUHLMANN KLAUS
IPC: H04Q11/04
Filed: 1988-07-14
Abstract: A parameter-controlled program which is identical for all terminals which can be connected to a communication system is in each case stored in the program memory of the terminals. This program implements all functions which can be allocated to the different terminal types. The functions provided for the respective terminal are allocated and controlled by parameter data stored in a data memory. The parameter data are initially transmitted by the communication system to the respective terminal, or updated, on the basis of an initialisation in the terminal or in the communication system. In a communication system designed in this manner, the terminal-individual flexible allocation of functions and procedures to the respective terminals is retained despite the movement of switching and operating functions into the terminal - which means a dynamic relief of the centralised control of the communication system.

Title: Electrical/electronic temperature monitoring with a remote alarm
Inventor: KAESBERGER FRANZ
IPC: G08B17/06
Filed: 1988-08-18
Abstract: In order to avoid self-ignition of feedstocks or other deposits at risk of self-ignition, an electrical/electronic temperature monitoring system with a remote alarm is provided. This temperature monitoring comprises at least one base temperature measuring probe (25) and at least a plurality of subordinate secondary temperature measuring probes (24) which automatically measure the temperature present, via a temperature sensor (4), at specific time intervals and indicate it digitally. In the case of an overshoot of a preset temperature limit value, an alarm signal is fed to the alarm evaluation electronic unit (12); and this transmits the alarm signal either via a radio transmitter (13), licensed by the post office, to a radio receiver (17) or, via an alarm triggering control lead (23), to the control part (16) of the alarm control box.   By this means, an optical and/or acoustic alarm signal (19/18), which is intended to be well perceptible at any time, is triggered. <IMAGE>

Title: Exhaust gas silencer
Inventor: SIEBELS JOHANN
IPC: F01N13/16
Filed: 1988-11-02
Abstract: An exhaust gas silencer for internal combustion engines is described, having a gas inlet and a gas outlet and having at least one monolithic element (5 to 7) consisting of sound-absorbing, porous material whose open overall porosity is between 50 and 95%, preferably between 60 and 85%, with a pore size of 0.5 to 5 mm. In order to provide an exhaust gas silencer of this kind with an optimum sound damping effect in virtually all operating ranges and frequency ranges, the intention is for each element (5 to 7) to be constructed in such a way that the exhaust gas must penetrate the porous material at least once as it flows through the silencer (1) from the gas inlet (3) to the gas outlet (4). During this process, each element (5 to 7) is to have walls (18a, 18b; 19a to 19f) formed by gas-tight areas of the porous material for guiding and reflecting the gas current, the gas-tight areas being formed by applying to the porous material an agent which closes off the pores and consists of a slip or bonding agent which sets in a hydraulic or chemical/ceramic fashion. <IMAGE>
