Patent DE-3819849-A1 (DE)
Inventor: RAUNER HANS DR
IPC: B62D6/02
Filed: 1988-06-10
Abstract: In-process computer-controlled active rear axle kinematic chain of a motor vehicle, the rear wheels of which are also steered by means of an electronically controlled control element. For automatic control of the rear wheels, the in-process computer makes allowance for the corresponding steering angle of the front wheel and/or values derivable therefrom, a possibly speed-dependent correction time constant, a possibly speed-dependent delay time constant; and a possibly speed-dependent delay time constant, and a possibly speed-dependent concomitant steering factor. The in-process computer processes parameters derived from scanning values and which correlate at least with these angles, according to a difference calculus equation, not according to a differential equation to be solved iteratively, and supplies the reference values for the rear axle or rear wheel steering angle and/or reference values derived therefrom to the control element.

Title: Steam cooking appliance
IPC: A47J27/04
Filed: 1988-06-16
Abstract: Steam cooking appliances comprise a cooking chamber in a housing for receiving the food to be cooked, it being possible to close the cooking chamber via a door articulated on the housing. A steam atmosphere for cooking food is generated inside the cooking chamber. When the door of conventional steam cooking appliances is opened, the water condensing on the inner face of the door drips onto the floor of the room in which the appliance is installed. It is proposed to arrange at the bottom edge of the door for closing the cooking chamber guiding means for catching condensation water running down on the inner face of the door and to provide these with a discharge opening so that the water which is caught can be carried away in a controlled manner.

Title: Number plate holder
Inventor: MOESCHL JOSEF
IPC: B60R13/10
Filed: 1988-06-28
Abstract: In the case of a number plate holder for fixing a motor vehicle number plate to the body, a plastic base plate and a covering frame which is also made of plastic and is pivotably mounted on the latter are provided which together delimit a receiving compartment for the number plate. Along the lower transverse edge of the number plate holder there are arranged at equal intervals at least three drag bearings, the bearing bolts of which extend between bearing flange extensions which are at right angles to the pivot axis, the said bearing bolts being fixedly connected to the said extensions and the eyelike bearing elements of the said drag bearings taking the form of sleevelike slotted bearing clasps which enclose the bearing bolts over a sector of about 240@. The length of the bearing clasps which extend between the flange extensions is approximately and about equal to that of the bearing bolts. The pivotable frame can be positively fixed in the locking position of the number plate holder by means of resilient locking tongues which can be made to engage with a locking groove in the base plate.

Title: Pressing or tensioning roller
Inventor: BENZINGER HEINZ-DIETER DIPL IN
IPC: F16H7/08
Filed: 1988-11-12
Abstract: In the case of pressing or tensioning rollers which are installed upright and the running flange of which engages over the mounting, the lubricating orifice is to be arranged only in the vicinity of the lower bearing row, so that, during re-lubrication, the upper bearing row is often not supplied with sufficient grease if an over-lubrication of the mounting is to be avoided. The possibility for re-lubrication is to be improved. The lubricating orifice (9) merges into a lubricating channel (10) which bypasses the mounting and which opens into the mounting at the free shaft end above the two bearing rows (4, 5). Ring-spinning or twisting machine with a belt drive. <IMAGE>

Title: Sensor arrangement for detecting gases by means of exothermic catalytic reactions
Inventor: NUSCHELER FRANZ DIPL ING
IPC: G01N27/18
Filed: 1988-11-22
Abstract: The sensor arrangement, a so-called planar pellistor, comprises two thin-film resistances (21, 22) which are contained, in a thermally insulated manner, in a semiconductor substrate. The two thin-film resistances (21, 22) are connected to one another in a circuit for difference measurement, e.g. a Wheatstone bridge circuit. At least the first thin-film resistance (21) is provided with a catalyst layer. The first thin-film resistance (21) is exposed to the heat formed in the catalytic combustion of a gas to be detected on the catalyst, while the second thin-film resistance (22) is insulated from this heat. Therefore, when a gas to be detected acts on the sensor arrangement, the resistance of the first thin-film resistance (21) changes, while the resistance of the second thin-film resistance (22) remains unchanged. The bridge circuit is therefore unbalanced (detuned), which is exploited for detection of the gas. <IMAGE>
