Title: Semiconductor sensor e.g. for controlling fuel injection or for antiblocking braking systems or auxiliary restraining systems
Inventor: YAMAMOTO MASAHIRO
IPC: G01P1/00
Filed: 1996-06-04
Abstract: The device includes a semiconductor sensor. It also has several operational amplifiers (3,5,8) to amplify an output of the sensor. The op-amps include an end stage operational amplifier (8) forming an inverting amplifier stage. A pull-up resistor (13) is connected with an output terminal of the end stage operational amplifier. A saturation device (10) saturates an output voltage of the end stage op-amp, when a voltage at the inverting input terminal of the end stage op-amp lies below a voltage threshold at which the output voltage from the output terminal is saturated. The saturation device may be a constant current supply connected in parallel to the pull-up resistor. Alternatively, a limiting device (20) may be provided to limit a voltage at the inverting input of the end stage op-amp so that the output voltage of the op-amp is not saturated.

Title: Alarm activation unit with locking stop
Inventor: WEISGERBER WILHELM
IPC: E05B45/06
Filed: 1996-09-16
Abstract: The activation unit includes a lock (ZS) with a bolt (R) in a leaf (TB). A bolt pocket (RT) is allocated to the bolt and a locking stop which locking function can be abolished electrically by a control unit of the alarm when the alarm is ready for activation.

Title: Dimensionally stable, untwisted, non-curved epoxide glass laminate production
Inventor: SCHAEFER HANS-JUERGEN DIPL ING
IPC: H05K3/02

Abstract: The continuous production of epoxide glass laminates with a double-band press uses a carrier web (6) coated with thermosetting epoxide resin, which is not precured and has a gelation time adjusted to 10-80 seconds at 170 deg C. The edges have a 2-20 mm wide and 50-200  mu m thick coating of fusible, radiation-curable epoxide resin, which has been cured with ultra-violet (UV) radiation at the edge. The web is fed to the lower, preferably predrawn, press band (3) of a double band press with at least two pressing zones by means of a laminating roller (5) heated to 40-60 deg C, and laminated to the copper foil (7) covering the surface of the band (16).  It is heated with infra-red (IR) radiators (4) and the band temperature to 160-180 deg C and precured to a residual gelation time of 5-15 seconds at 170 deg C. It is then converted to the B stage in a first, preferably isochoric pressing zone (2) at 5-10 bar and 170-180 deg C, cured in a second pressing zone (1) at 10-20 bar and 180-190 deg C, preferably to a degree of cure > 50%, and finally post-cured in 60-120 seconds in an oven (20) at 20-220 deg C.

Title: Roll shutter box slot seal of elastically deformable material
Inventor: PRANGENBERG WILLI
IPC: E06B9/17
Filed: 1996-12-14
Abstract: The support (5) and the seal (6) are arranged exclusively in the inside part of the shutter slot (2) whose outside is fitted with a slightly elastic plastics or rubber profile strip (9). In detail, the slot is slightly wider than shutter thickness thus leaving a narrow gap both sides of the shutter slats.

The support can be of metal or plastics and is open in U shape to the front to accept the rubber etc seal (6) bonded to the support base (5). The seal remains exposed at the support legs (7,8) and comes in the form of a hollow rectangle, walled to permit an elastic change of shape or expansion. The seal can be inflated with air at 1-2 bar via end connection and air valve, running off a blower etc thus changing the seal shape so it expands towards the shutter slat (3) thus forcing this slat into the profile (9) to complete the shutter seal-off action.

Title: Adaptive encoding method for digitised video signal
Inventor: NG HAK-LEONG
IPC: H04N7/50
Filed: 1997-04-11
Abstract: The method involves dividing a video image into blocks which are subsequently encoded. A number of coding processes are used on every block resulting in the shortest code used. The method involves intercoding of the blocks to produce an intracode with the shortest code being transmitted. The code to be selected has to be shorter than a threshold value or else a second code will be generated. The rate at which the processor is used determines the imposed load of the encoded data, which load is monitored not to exceed another threshold value. The transmitting channel is monitored as well not to exceed the assigned bandwidth for the data transmission.

IPC: H02H7/085
Filed: 1997-06-13
Abstract: The invention relates to a method for protecting direct current motors from thermal overload. According to the invention, a temperature of the direct current motor is detected and compared with a predetermined maximum temperature. In the event that the maximum temperature is exceeded, the voltage supply of the direct current motor is interrupted. A rotor temperature (TR) of the direct current motor (10) is determined from an armature current (IA) and an ambient temperature (TM) of said direct current motor (10). Said rotor temperature (TR) is compared with a maximum allowable temperature (Tmax), and a supply voltage is timed by a control unit (26) in accordance with this comparison between the rotor temperature (TR) and the maximum admissible temperature (Tmax), said control unit providing the supply voltage to the direct current motor (10).
