Title: Vacuum cleaner base nozzle with brush roller and rpm controlled roller motor drive - has control unit which influences brush roller drive rpm depending on sensed load current alterations of electric drive motor with suction operation
Inventor: BUEKER WILFRIED
IPC: A47L9/04
Filed: 1991-11-15
Abstract: The electric motor brush roller drive is controlled by a load torque limiting unit, in the manner of an electronic slip clutch. The supply voltage of the drive motor in the event of a load current limitation is not switched off. An over-dimensioned drive motor is used as the electric drive motor with a max. torque, which exceeds a rated torque (safety torque), required for brushing carpets with a large pile density and a large pile height, to which a predetermined load current limit value is assigned, and with which the brush roller does not lock. The load current limiting unit is a phase chopping controller, which in suction mode, on reaching the load current limit value, prevents any further current increase at the drive motor, by lowering the supply voltage. ADVANTAGES - Improved optimised processing of all textile floor coverings without risk of damage to e.g. carpet. Minimises operational interruptions due to safety measures.

Title: Vehicle headlamp with enhanced illumination when dipped - has filter to remove UV B and to project UV A beyond normal light spread to illuminate fluorescent road markings
Inventor: BEFELEIN CARSTEN
IPC: F21V11/16
Filed: 1991-12-18
Abstract: The conventional headlamp is improved by including filters which add UV A to the light beam. Due to the different focal conditions, and with the positions of the UV filter, the UV A beam is projected farther than the visible light beam and illuminates fluorescent markings e.g. on roadside posts. The UV A wavelengths are on the edge of the filter while the harmful UV B radiation is totally absorbed by the filter. The filtering can be via a filter plate inside the headlamp, or by a coating on the reflector, or incorporated in the lens. Reflector coatings includes quartz, LiF and MgF2. The intensity of the UV A is not high enough to affect other road users. ADVANTAGE - Improved safety i.e. driver can identify road markings at greater distances.

Patent DE-4320056-A1 (DE)
Title: Laser hot-air micro-radiator
Inventor: AZDASHT GHASSEM DIPL ING
IPC: B23K26/14
Filed: 1993-06-17
Abstract: The device is suitable for soldering and desoldering or for the thermal treatment of a surface with a heated gas medium. The construction consists of a holder (1) for accommodating the light fibre and the gas-permeable absorber. The thermal energy is produced in the absorber (3) by a laser (2) via a glass fibre (3). The absorber is made of a temperature-resistant material which is designed as a wool-like structure or compressed fine balls. The porosity resulting from this provides for both the permeability of the gas medium and higher absorption capacity of the absorber. The laser energy converted into heat in the absorber is passed out of the discharge channel of the holder (6) by flow of the gas (5). The gas flow produced in this way is available for the treatment. The temperature of the gas flow depends on the laser power, the absorption capacity of the absorber, the gas medium and its rate of flow. <IMAGE>

Patent DE-4330322-A1 (DE)
Title: Motor vehicle with integrated jack
Inventor: DWORSCHAK KARL
IPC: B60S9/12
Filed: 1993-09-08
Abstract: The invention relates to a motor vehicle with at least one jack which is integrated in its body and can be extended and retracted by supplying energy. Such integrated jacks are known from racing cars where they are usually supplied with hydraulic power at a pit stop so as to permit the wheels to be changed rapidly. When activated, these jacks immediately move out of their retracted position into a limit position in which the wheels of at least one side of the vehicle are lifted off from the ground. In order to make an integrated jack suitable for use as a protection against theft, according to the invention the jack is designed in such a way that it can be moved into an intermediate position in which the lower end is at least approximately in contact with the ground as a protection against theft. By only extending it enough to produce contact with the ground without further applying force so as to lift off the vehicle from the ground, an extremely effective immobiliser is obtained. Nevertheless, if such a jack is extended further as far as a second stage it is still entirely suitable to be used in its function for changing wheels.
