Title: Antitheft lock for vehicle
Inventor: YOSHIZAWA TAKASHI
IPC: E05B81/64
Filed: 1996-11-18
Abstract: The vehicle door lock system has two modes of locking; one setting in which the main catch is locked but the lock can be opened by lifting the control buttons on the inside of the door, and one setting in which the lock is secured and release buttons are blocked. A motion sensor detects movement inside the vehicle and moves the lock setting into first mode. The safety release of the lock into the first mode occurs if the motion sensors detect movement within a set time after locking the doors. If movement is detected only after a second set time interval this signifies an intruder. The control system then sets the locks into the second, secure mode.

Patent DE-19707227-A1 (DE)
Inventor: WULF JUERGEN DR
IPC: G02B26/10
Filed: 1997-02-24
Abstract: The present invention relates to a light sensing device for exciting and detecting an emission of secondary light, especially of fluorescent light, from a test sample (40), comprising a light producing device (20) for producing sensing light in the form of a single bundle of light rays (21), as well as a deflection unit (10) to deflect the sensing light in at least one modifiable direction in order to sense at least one partial surface of the test sample (40), an imaging unit to image secondary light emitted from the test sample, and a detection unit to detect the secondary light. Unwanted long sensing times occur during fluorescent examination of a test sample having a large sensing surface and high local resolution. In order to reduce sensing times while maintaining high local resolution of said test samples, the inventive light sensing device has a splitting device (110) to divide the single bundle of light rays into at least two bundles of light rays (22,23), thereby resulting in a sub-division into fields instead of the usual sequential sensing of the test sample, said fields being simultaneously sensed by several beams of light. Sensing time can thus be reduced according to the number of simultaneously sensed test sample fields.

Patent DE-19717469-A1 (DE)
Title: Power recovery method using heat recycling machine
Inventor: LAUBKEMEIER FRIEDHELM DIPL ING
IPC: F02G1/044
Filed: 1997-04-26
Abstract: The method involves a three-stage thermodynamic cyclic process for three equal gas masses, consisting of an adiabatic compression stage (1-2), an isobaric expansion stage (2-3) with heat input and a contraction and pressure generation stage (3-1) involving heat extraction and internal thermal recycling. The three gas masses successively undergo three states of temp. and pressure, each offset by one stage as they pass through the stages. The required mechanical energy for compression is generated by the device itself and the energy required for isobaric expansion is mainly extracted from the pressure generation and contraction phase.
Patent DE-19723653-A1 (DE)
Title: Safety disconnector e.g for commercial and domestic gas-burning apparatus
Inventor: KIM HYUN-HAG
IPC: F23D14/72
Filed: 1997-06-05
Abstract: The device has a safety valve (106) arranged to open and close a gas inlet. A thermoelement (101) generates an electromotor force under the effect of heat. A magnetic force generator (102) decreases the electromotor force from the thermoelement (101) and thus generates a magnetic force to keep the safety valve (106) in its gas inlet open position. A switch off circuit applies a counter electromotor force to the magnetic force unit (102) when a gas supply or gas inlet is to be switched off or blocked. The device may have a timer which switches the device off after it has been on for a given or pre-set time. The device may also have a trigger switch for manually displacing the safety valve into its gas inlet open state in a start phase of the gas burning apparatus.

Title: Measuring apparatus for determining polarisation mode dispersion of optical elements e.g. glass fibre conductors
Inventor: GOTTWALD ERICH DR
IPC: G01M11/00
Filed: 1997-06-11
Abstract: The device has a laser (L) and a modulator (M) for optoelectronic conversion of a measurement signal. The apparatus also has at least one polarisation control member (P) at the input of the optical element (TS) to adjust the polarisation of the optical signal output by the modulator (M). A signal detector unit (NWA) at the output of the optical element (TS) determines the phase position of the optical signal at the output of the optical element (TS).  A signal analyser unit (AE) is connected after the signal detector. The signal analyser calculates the difference in signal propagation time between a maximum and a minimum phase position with different polarisation positions of the control member (P) with different wavelengths. The polarisation mode dispersion is derived from the statistical distribution of the time differences.
Patent DE-19725790-A1 (DE)
Inventor: FISCHER GERT
IPC: B24D3/00
Filed: 1997-06-18
Abstract: Character strings inter alia are inputted into a data processing unit (1) during the normal course of operation. Said strings are outputted in a sequential character sequence via an output interface (4). The primary output signal flow thus produced is formatted in such a way that it can control an available printer (5). Position control signals added to the output signal flow cause the printer (5) to output a respectively allocated character string in a given output position. According to the invention, a converter (6) is coupled to the output interface (4) and placed in a configuration mode. The data processing device (1) is allocated a marking character string ("A06AAA") instead of each character string which is to be detected selectively. The output signal flow is received by the converter (6) and searched for marking character strings. When a marking character string is detected, identifying position information relating to the point of origin in the output signal flow is obtained from the position information signals which are also transmitted and stored along with the number of characters in the converter(6). In the subsequent operating mode, any number of character strings are detected in the marked positions of the output signal flow using stored position information, they are read and can be subsequently integrated with a secondary output signal flow in an appropriate manner. The format of the secondary output signal flow is modified according to an alternative output device (14). The signals constituting the secondary output signal flow are formed by data from an output memory (B) and by the character strings of the first output signal flow which are read from a memory (A) using a control device (8).
