Patent DE-3816018-A1 (DE)
Title: Protective circuit for infrared receivers
Inventor: SCHRAMMEL FRANZ
IPC: H04B10/60
Filed: 1988-05-10
Abstract: Protective circuit for receivers of infrared transmission systems with pulse interval modulation with a plurality of transmitters for protection against interfering multiple reception in overlap areas of two or more transmitters. Two timers (5, 6) which are connected to the pulse input of the demodulator (1) recognise pulse intervals of the infrared pulse telegrams which on the one hand are shorter than the minimum pulse interval and on the other hand are longer than the maximum pulse interval of an interference-free pulse telegram. Both timers (5, 6) are connected via a gate circuit (7, 8, 9) to a third timer (10) which, following the activation of one of the two first timers (5, 6), interrupts the transmission path from the receiver (1) to the acoustic sound generator (4) for a pre-defined period (blocking time). <IMAGE>

Inventor: MATSUI FUMIO
IPC: G11B7/24097
Filed: 1988-06-10
Abstract: An optical disc for information exchange has two different areas, one of which is wider than the other, each of the areas containing a different track information format, so that a device can analyse the optical disc without regard to the track information format which is configured in the device. The two areas may be separated from each other by a third disc area which does not contain any track information.
Patent DE-3823384-A1 (DE)
Title: Torsional vibration damper
Inventor: REIS OSWALD DIPL ING
IPC: F16F15/134
Filed: 1988-07-09
Abstract: The springs (C1, C2, C3) of a torsional vibration damper, which are arranged in the drive line of a motor vehicle driven by an internal combustion engine, form, together with the two masses (S1, S2) coupled to one another in torsionally elastic fashion by the springs (C1, C2, C3), a torsional vibration system with a natural frequency that is normally below the idling speed of the internal combustion engine. In order to avoid resonant vibrations, particularly those which occur when starting and stoppng the internal combustion engine, one of the components of the torsional vibration system which determine the natural frequency, for example a spring set (C1, C2) operating in the active load range, can be switched between two states and, in the two states, defines two different natural frequencies of the torsional vibration system. A control (E) responding to the operating speed of the internal combustion engine, for example a centrifugal control, adjusts the state of the switchable component of the torsional vibration system in such a way that the natural frequency of the torsional vibration system always lies above or below the vibration frequency of the torsional vibration system excited by the instantaneous operating speed. <IMAGE>

Title: Dormer window
Inventor: BAUER GUENTHER
IPC: E04B7/18
Filed: 1989-02-25
Abstract: The invention relates to a dormer window comprising prefabricated principal structural parts which can be connected to one another on site, in particular two side parts, a front part and a roof part, the structural parts comprising load-bearing frames made up of interconnected profiles, and a cladding being fastened on the outer side of the load-bearing frame such that the load-bearing frame remains freely accessible in its interior, and thus from the inner side of the dormer window.

Title: Door lock which can be heated
Inventor: BLIHA JANOS
IPC: E05B17/00
Filed: 1989-03-13
Abstract: Particularly in the case of motor vehicle door locks, it is not possible completely to prevent moisture from penetrating into the inside of the lock. When the outside temperatures are low, the moisture which has penetrated into the inside of the lock freezes and in this way blocks the lock. The object of the invention is to make it possible to thaw the lock without external auxiliary means. To this end, the lock is provided with a heating coil (20) arranged at a distance from the circumferential surface of the lock housing (10). A heating current can be applied to the coil (20) by means of a battery (40) arranged in the interior of the vehicle, preferably the vehicle battery, using electrical switch contacts (45, 46) which can be connected to one another from outside the vehicle and which are formed in particular by an electrical switch (50). <IMAGE>

Title: Control system for an internal combustion engine
Inventor: WAHL JOSEF DIPL ING
IPC: F02D41/14
Filed: 1989-06-19
Abstract: A control system is described for an internal combustion engine with autoignition. The control system comprises sensors for detecting characteristic operating variables, an electronic control device and an actuator for influencing the amount of fuel to be fed to the internal combustion engine. In a first step, a basic value (ME) for the amount of fuel is calculated as a function of at least the engine speed and the position of the accelerator pedal. This basic value for the amount of fuel is corrected in a second step, the correction taking place as a function of the exhaust gas temperature signal. The exhaust gas temperature signal used for correction is calculated from the measured exhaust gas temperature signal and other characteristic operating variables. <IMAGE>
