Patent DE-2919378-B1 (DE)
Inventor: DOERING ERICH
IPC: E06B3/76
Filed: 1979-05-14
Abstract: Garage doors for single or double garages have a door wing, the frame of which is provided with a door leaf made of painted or plastic-coated profiled sheet-metal panels (13, 14) with profiling running parallel to the vertical side edges of the door leaf. The profiled sheet-metal panels (13, 14) which are separated from a longitudinally profiled sheet-metal web originate, as a result of the different width necessary, from different batches if no waste is to occur. The coatings of profiled sheet-metal panels from different batches fade differently in time. In order to avoid this, the door leaf has, running parallel to the upper and lower edge of the door leaf, a central transverse frieze (11) of the necessary width and, above and below this, in each case a single profiled sheet-metal panel (13, 14) reaching from one side edge to the other, which is separated from a transversely profiled sheet-metal web and in each case is connected at the same height to the frame and the transverse frieze (11). Identical transverse friezes (10, 12) are preferably also provided on the upper and lower edge of the door leaf. <IMAGE>
Patent EE-03532-B1 (EE)
Inventor: HABICHT SIEGFRIED
IPC: E06B3/263
Filed: 1997-09-16
Abstract: The insulating strip (11) is joined to the lengthwise edges of the metal profiles and is positioned between the metal profiles (5,6). The shear strength in all the lengthwise connecting parts between the outer metal profile (6) and the insulating strips may be low, whereas the shear strength between the inner metal profile and the insulating strips may be high. The slide-ways could have guide surfaces (14,15) at right angles to the centre axis (16) of the insulating strip. The insulating strip(s) may be mounted in a back-tapered guide groove (18) defined by the metal profile's edge strips (19,20) which in turn can define a lengthwise opening (21) through which one arm (22) of a guide extension arm (13) extends. The extension arm can be integral with a cylindrical guide part (17) gripping behind the edge strips.

Abstract: A method for assisting starting of a motor vehicle by application of engine torque on starting the vehicle. In the method parameters for detection of the starting of the motor vehicle are recorded. A set point for engine management is calculated from a parameter for the driver's command. A torque for assisting the start is determined from the engine management set point. The torque assistance is used on starting the vehicle from zero speed to a non-zero speed and the set point for the engine management is calculated as a function of different values for the moment of inertia of the engine. The change from one first value to a second value is carried out on there being a given difference between the engine management value and the measured value.

Abstract: The present invention relates to the detection of intruders (human beings, vehicles or animals) in a protected zone and the departure of individuals from this zone. One or more embodiment of the invention relates to a device which includes a plurality of individual standalone electromagnetic sensors placed on the perimeter of the guarded zone so as to substantially cover this perimeter, and a central unit placed close to the perimeter surrounding the guarded zone. Each sensor takes a measurement of the angular position and of the speed of an intruder present in the zone that it covers. These measurements are relayed to the central unit from the sensor having detected the intruder, through a communication network formed by all of the sensors. The central unit processes the data transmitted by the various sensors and periodically determines the position and trajectory of the detected intruders. The invention applies in particular to the guarding of civil and military infrastructures (airports, factories, oil pipelines, gas pipelines, ports, railways etc.) or of private zones (properties, estates).
