Patent DE-4205858-A1 (DE)
Title: Overhead electric railway with pressure roller underneath rail - which is pressed against rail by torque reaction of driving motor.
Inventor: ROSENAU VIKTOR DIPL ING
IPC: B61C13/04
Filed: 1992-02-26
Abstract: The driving wheel (8) is driven by an electric motor (5) mounted above the rail. A roller (9) is pressed against the underside of the rail. The pressure roller (9) is mounted on an L-shaped lever (10) which is pivoted to the frame from which the carriage is suspended. The reaction to the driving torque exerted on the wheel (8) causes the driving motor (5) to swing through an angle (b1 or (b2). This motion of the driving motor is transmitted to the L-shaped lever either through the chain (12) or through the roller (13) so that the L-shaped lever rotates through a small angle and presses the roller (9) against the underside of the rail. USE/ADVANTAGE - The increased friction between driving wheel and rail enables ascents to be climbed more easily and provides greater braking power on descents.

Title: Locating stolen cars and deterring thieves - having radio telephone transmitter=receiver unit concealed in vehicle and activated by call after vehicle is stolen
Inventor: RICHTER JOERG
IPC: G01S1/68
Filed: 1992-12-01
Abstract: The method involves using radio telephones involving either the C or D1/D2 network. When a vehicle equipped with the system is missed an area call is made to an allocated number, e.g. by the police. The response signal from a unit in the vehicle is detected by the nearest base station to it. The base station relays the signal to the central station. The areas in which the vehicle is located are tracked and eventually the direction of travel of the vehicle is determined. Measures are taken to make the vehicle's receiver/transmitter unit difficult for thieves to locate and disable. USE/ADVANTAGE - Provides protection against car thieves at reduced cost compared to similar systems.

Patent DE-4308781-A1 (DE)
Title: Hollow moulding of plastic
IPC: B29C45/00
Filed: 1993-03-19
Abstract: A hollow moulding is made up of two injection-moulded halves bearing against each other along a parting surface. The parting surface has no constant angle with respect to a demoulding direction of the two parts. At the parting surface, the two parts of plastic have projections and/or depressions, which do not form an undercut. Two side faces of a projection and of a recess, respectively, are intended for bearing against each other. On account of force components perpendicular to the deforming direction, a locking or latching is made possible without there actually being any undercut.

Title: Apparatus and method for a contactless mouse-compatible PC pointer input device
Inventor: KUIPERS ULRICH PROF DR ING
IPC: G06F3/038
Filed: 1993-04-19
Abstract: The PC can be controlled, via a sensor poster hanging, for example, on the inside in the shop window (display window), from the outside, through the pane without additional aids by means of simple hand movements. The contactless operation of the PC without further aids through the pane ensures optimum protection from damage and wear. The sensor principle is based on capacitive measurement effects. Capacitances are measured between various sensor areas on a sensor field or a sensor poster and a part of the body of the operator, preferably his/her hand. The movement of the cursor or pointer on the screen is controlled by means of the measured capacitance changes. Areas of use include interactive offer presentations on PC monitors in shop windows, user-controlled measured data presentations or information systems exposed to the environment as well as controllers in an area where there is an explosion risk or control devices which are suitable for handicapped people. In another embodiment according to the invention with a greatly reduced sensor field, the movement of the finger of the operator serves as pointer input for contactless control of a PC, a laptop or a notebook.

Title: Process for dirty water disposal in the wet cleaning of furnaces
Inventor: BREITHAUPT JOCHEN
IPC: E03F5/16
Filed: 1993-10-26
Abstract: In a process for dirty water disposal in the wet cleaning of furnaces, in particular oil furnaces, the polluted dirty water arising is passed into a separator collection vessel and the collected liquid is admixed with caustic soda (sodium hydroxide solution), the liquid being adjusted to a pH between 8 and 9. The suspended matter formed during this process containing the deposited pollutants settles out at the vessel bottom, so that the pollutant-free water situated above the sludge layer can be passed into the sewage system after a certain settling time. The settled sludge layer which, at about 10%, makes up only a small portion of the total amount of liquid necessary for the wet cleaning, is disposed of as special waste.
