Title: Man's hand-held battery shaver - has two combs with interlaced teeth, one comb driven directly by motor with linear or rotary oscillation
Inventor: CLEYET AIME
IPC: A45D26/00
Filed: 1992-11-26
Abstract: A man's hand-held shaver has a motor with gearbox driving a pair of combs. Only one comb is driven directly and its motion may be linear or oscillatory, using either an eccentric rod or eccentric cam with follower. The second comb is driven by the first, its teeth fitting loosely between the teeth of the first comb. A spring with a brake shoe, holds it in place until the teeth of the first comb take up the slack and move the two combs as a unit to the end of a stroke. Again, the second comb is held in place while the first comb reverses. When the slack between combs is taken up, the two combs return as a unit. ADVANTAGE - Gives close shave.

Title: Defrosting of inverter-driven air conditioning plant - using outdoor measured temperature to initiate defrost, with compressor frequency controlled to give constant defrost time
Inventor: TAE-DUK KIM
IPC: F25B47/02
Filed: 1992-12-22
Abstract: A procedure is provided for defrosting an inverter-driven air conditioning unit where the rime on the outdoor heat exchanger is melted off. First, it is determined whether the temperature measured by a sensor on an outdoor duct is appropriate for the initiation of defrosting and then a four way valve is adjusted to block the flow of cooling medium so that the defrost cycle can commence. Next, the defrost condition is evaluated and the compressor drive frequency and heating element phase are changed so that the defrosting takes a preset time dependent on the measured temperature. The defrosting process is then monitored continuously with adjustments in these two parameters if necessary. ADVANTAGE - Defrost time determined by measured temperature of outdoor duct.

Title: Signal luminaire for motor vehicles
Inventor: DECKER DETLEF
IPC: F21S8/10
Filed: 1993-02-24
Abstract: A signal luminaire for motor vehicles has a number of light sources which are constructed as light emitting diodes and a number of lenses corresponding to the number of light emitting diodes, each light emitting diode being assigned a lens and the light entrance surface, facing the light emitting diode, of each lens having two light-collecting regions. So that the emitted light is utilised as well as possible when light emitting diodes are used which have a broad cone-shaped light emission from at least two focal points or one elongate focal point, the second light-collecting region has a circumferential total-reflection prism which deflects a partial region of the light emitted by the light emitting diode in a cone-shaped manner, to produce essentially parallel light.

Title: Electric circuit for a monitoring light which can be actuated by a parking brake of a motor vehicle
Inventor: BECK MARTIN DIPL ING
IPC: B60T17/22
Filed: 1993-06-23
Abstract: An electric circuit for a monitoring light which can be actuated by a parking brake of a motor vehicle operates in such a way that the monitoring light is switched on when the parking brake is engaged and is switched off when the parking brake is released. In this arrangement, the circuit has a subcircuit which is connected to voltage via the actuation of the ignition and in which the monitoring light and a switch which can be actuated by the parking brake are connected in series. A transistor whose base is connected to a control unit which is driven by the speed of the vehicle is arranged in the circuit connected in series with the monitoring light and the switch which can be actuated by the parking brake. By means of such a design of a circuit for a monitoring light which indicates the respective position of the parking brake the possibility of the monitoring light being overlooked by the driver of the respective motor vehicle is virtually excluded and in this way unnecessary consumption of energy and wear of the brakes can be avoided. In addition, the safety of the vehicle is increased since the power of the engine is prevented from being adversely affected by a parking brake which has been put on inadvertently.

Title: Two-legged stand for photographic equipment - has swivel mounted legs attached with restricted movement to avoid unrequired tilting of supporting bridge.
Inventor: BLUMENBERG DIRK DR
IPC: F16M11/20
Filed: 1993-10-06
Abstract: The two fixed or telescopic legs (2) are attached for swivel movement to a bridge (1) with central bore (7) for fixing the camera.

Title: Cleaning and restoring ground contaminated by DDT
Inventor: PAETZ REINHARD DR RER NAT
IPC: B09C1/02
Filed: 1994-03-07
Abstract: Restoration results from a combination of physical, chemical and microbiological reactions. The uplifted contaminated ground is preclassified into coarse and fine grain material over a screen. The fines enter an agitated boiler (2) to be mixed intimately with a water soluble solvent, extracting most or all of the DDT. The solvent, pref. butyl acetate, dissolves DDT and is also biodegradable. The residence time depends upon the DDT concentration; afterwards the suspension enters the separator (3) where the fines are sepd. for return to ground. Further processes follow, including aerobic and anaerobic degradation of the solvent-water-DDT mixture.
Patent DE-4408173-A1 (DE)
Title: Ground stabilisation method for road=building and other earthworks
Inventor: MOEBIUS WERNER DIPL ING
IPC: E01C3/04
Filed: 1994-03-10
Abstract: The stabilisation method is carried out by first extracting column-shaped regions of material of insufficient load-bearing capacity. A surrounding lining of a high-tensile strength material, such as a geotextile, is then introduced into the hole. The hole is back-filled with material of sufficient bearing strength, and compacted within the confines of the lining. The process is repeated at discrete positions, and tubular frameworks may be used to assist the lining process. These may also be removed after the back-filling process has been completed.
