Title: Cleaning appts. for e.g. vehicle(s), windows etc. - uses combination of oscillation and air streams to detach and remove dirt in a sealed system
Inventor: HAG RENE
IPC: A47L25/00
Filed: 1992-05-16
Abstract: The appts. to clean object by oscillating streams, without water, has a housing of a suitable size which is sealed and impermeable, to generate the oscillating stream cleaning action and remove the detached dirt in a closed system for biological degrading. A system to remove detached dirt directly from the object (RO/RO-T) is in the housing with a suitable filter to prevent back soiling of the object, using an air stream and suction to carry it to a collection container (DD). The cleaning capacity of the oscillation/streams is set manually or automatically such as by computer according to colour and decoration and the high-technology ultra-fine cleaning action. The holder for the object (RO) to be cleaned is oscillated so that all parts (RO-T) are cleaned effectively, and the cleaning action is ended manually or automatically. The system can be moved past objects, such as in a kitchen situation, to apply the oscillation and stream actions as it is moved. A medical application uses a housing unit applied to the skin for a hygienic cleaning action and dirt removal. A housing unit applied to wallpaper also detaches the dirt for collection in a sealed system. A further appts. with a finer cleaning action in the molecular range of the remaining dirt can be used subsequently. The system can also be used with a razor etc. USE/ADVANTAGE - The system is for cleaning small objects, large items such as vehicles, or large surfaces such as windows and walls. The operation releases no dirt or chemicals into the environment, and the detached dirt is collected for controlling disposal.

IPC: C21D1/74
Filed: 1993-03-19
Abstract: A process for producing a carbon-containing gaseous treatment atmosphere in a thermal-treatment system, especially for treating ferrous materials, by introducing hydrocarbon compounds and air into a combustion chamber and delivering the combustion gases to the thermal-treatment system involves   a) operating, in a first exothermal reaction stage, the combustion chamber with an excess air coefficient n < 1.2, the formation of soot being avoided, and b) admixing, in a second endothermal reaction stage, the combustion gases from the first reaction stage with at least one hydrocarbon compound in such an amount that H2O and CO2 contained in the combustion gases of the first reaction stage is converted, by means of a catalyst, into CO and H2, the heat of reaction from the first reaction stage being supplied, at least in part, to the second reaction stage.

Title: Vehicle hydraulic brake system with antilock device
Inventor: VAN ZANTEN ANTON DIPL ING DR
IPC: B60T8/1764
Filed: 1993-03-24
Abstract: A proposed vehicle hydraulic brake system with two brake circuits has an antilock device and is also developed to improve the vehicle's tracking by automatic braking, especially when cornering. In automatic braking a servo pressure source delivers pressure medium into the antilock device for supplying the wheel brakes. For this purpose one isolating piston per brake circuit is situated between the servo pressure source and the antilock device. The fact that each isolating piston has its own cylinder with cover is disadvantageous. It is proposed, in order to save costs, to accommodate the two isolating pistons (314, 315) in an integral cylinder (301) with a blind hole bore (302). <IMAGE>

Title: Apparatus for the internal high-pressure forming of a tubular blank
Inventor: OSWALD JUERGEN DIPL ING DR ING
IPC: B21D26/02
Filed: 1993-03-25
Abstract: On an apparatus for the internal high-pressure forming of a tubular blank (3) made from ductile metal in a tool (1) having a die cavity, a pressure-medium feed (6) can be displaced axially behind the blank (3), the said feed being connectable to the end of the tubular blank (3) with sealing being provided by a flexible sealing ring (15; 25). In the tool (1), the die cavity adjoins a cylindrical cavity section (2), this section being open from the side of the tool and surrounding the tubular blank (3) at this point. A stub (10) of the pressure-medium feed (6) reaches into the said cylindrical cavity section (2) and into the end of the tubular blank (3) and here supports the sealing ring (15) on a circumferential surface (14) in front of an annular end face (13) in such a way that the pressure medium presses the sealing ring (15) against the end face (13) and, at the same time, by compression, against the inner surface of the tubular blank (3) and against the said circumferential surface (14). Arranged in front of the relatively hard sealing ring (15), which has an angular cross-section to match its contact surface (14; 13; 3) there is preferably another sealing ring (16) of softer material and of round cross-section on the same circumferential surface, which is then conical, this sealing ring coming to rest leaktightly against the inner surface of the tubular blank (3) before the first sealing ring (15) and pushing the first sealing ring (15). <IMAGE>

Title: Arrangement for actuating a friction clutch of a motor vehicle
Inventor: KUHN THOMAS DIPL ING
IPC: B60T8/32
Filed: 1993-05-17
Abstract: The proposal is for an arrangement for actuating a friction clutch (3) of a motor vehicle in which the clutch (3) is actuated automatically by means of a clutch control unit (11) and of an actuator (9). The motor vehicle furthermore comprises a traction control arrangement, the control circuit (25) of which controls an actuator (29) acting on a power-adjusting element (31) of the internal combustion engine (1) when an existing or incipient loss of traction is detected. In order to avoid the control systems influencing one another, the control circuit (25) produces a control signal during the situation involving a loss of traction and, in response to this signal, the clutch control unit (11) holds the actuator (9) of the clutch (3) in the clutch position existing at the beginning of the loss of traction and/or reduces the actuating rate of the actuator (9). <IMAGE>
