Title: Lighting for the passenger compartment of a vehicle
Inventor: KEMPF MARCELL DIPL ING
IPC: B60Q3/02
Filed: 1986-06-21
Abstract: A switch-off delay device serves for the delayed switching off of the lighting of the passenger compartment of a motor vehicle. It has an electronic switch which is connected parallel to the control contact or contacts and a timer actuator. Preferably a transistor whose collector-emitter junction is connected parallel to the control contact or contacts is used as the electronic switch. A series connection of a capacitor and of a diode which is connected parallel to the contact(s) serves as timer actuator, the capacitor being located in the actuator circuit of the transistor, the diode being connected in the blocking direction with respect to the supply voltage and the connection of the two components being connected directly to the control terminal of the electronic switch. When the door is open and the control contact is closed, the capacitor discharges via the diode and the control contact. After the door is closed, the control contact is opened and the capacitor is charged via the fuse, the lamp and the base-emitter junction of the transistor. As a result, a control current is produced which switches on the transistor so that the collector-emitter junction becomes low-impedance and the lamp continues to give light. With increasing charge of the capacitor, its charging current, and thus also the actuation current for the transistor, drop so that the collector-emitter current of the transistor also decreases slowly and the lamp goes out gradually. With the opening of the door, the ... described at the beginning starts ... Original abstract incomplete.

Title: Conveyor system for moving non-motorised toy vehicles on a toy track
Inventor: RAATZ ERICH
IPC: A63H18/10
Filed: 1986-07-29
Abstract: A stream of slide members, consisting of a plurality of slide members arranged in endless sequence, is used as a transport medium for a dog entraining the toy vehicle, the stream of slide members being located immediately below the track surface in a guide system (e.g. a channel) and forming a circuit when the track is assembled to form a circular path. By driving a transmission engaging into this circuit, the slide members are automatically advanced, driving each other, a non-specific number of slide members being equipped with an entraining mechanism (e.g. a magnet). The toy vehicle merely needs to be equipped with, for example, a magnet on its underside in order automatically to follow the stream of slide members when placed on the toy track.
Patent DE-3631975-A1 (DE)
Inventor: EHS EUGEN
IPC: F16J12/00
Filed: 1986-09-19
Abstract: The invention relates to a pressure vessel, particularly to a drier vessel for a vehicle air conditioning installation, and a method for making it. In the production of known pressure vessels, a hollow core body optionally provided with auxiliary winding bodies is provided with an outer winding layer of fibre-reinforced plastic acting to improve the resistance of the vessel to internal pressure. The production of such pressure vessels is rather expensive, because the core body and auxiliary winding bodies have to be separately prepared and formed to the desired shape of the finished pressure vessel. A relatively inexpensive and low-weight pressure vessel particularly suitable for use as a driver vessel in a vehicle air conditioning installation is provided according to the invention by the employ as said core body of a cylindrical standard blank from the mass-production of spray dispensers or beverage containers having at least one open end which is deformed as by press-forming, roll-forming or chasing to the shape of the top portion of the vessel. To further reduce the production costs of the pressure vessel the invention provides that the upper and lower ends of the core body are provided with respective coupling elements by means of which a plurality of core bodies may be interconnected in coaxial alignment to thereby form a winding unit to which the winding layer may be applied in a single operation. The auxiliary winding body is likewise formed of a standard blank from the mass-production of spray dispensers or beverage containers. Standard blanks of the type referred to are commercially available at low cost and in different sizes.

Inventor: SWANSON ERIC JOHN
IPC: H03K5/08
Filed: 1987-10-29
Abstract: Method for decreasing the recovery time following an input voltage overdrive. At the beginning of a comparison cycle the control and timing circuitry 32 momentarily asserts a signal (ERASE) which, by means of a switch 30, applies a reverse voltage between the gates 20, 21 and sources 34 of the input pair of source-coupled MOS transistors 14, 16 of sufficient magnitude to form a charge accumulation layer in the channel region of each of the transistors. Operating the differential voltage comparator 28 in such a manner substantially decreases the time required by the transistors 14, 16 to recover from the imbalance in their electrical characteristics caused by the input voltage overdrive.

Title: Brake-pressure adjusting device
Inventor: ZIVKOVIC MILORAD DIPL ING
IPC: B60T13/12
Filed: 1987-12-19
Abstract: In a hydraulic double-circuit brake system of a road vehicle equipped with an anti-lock system (ABS) and with a drive-slip control device (ASR), a twin master cylinder, the master-cylinder piston of which is displaceable via a torque-compensated rocker, is provided as a brake unit. For that master cylinder of the brake unit which is assigned to the wheel brakes of the driven vehicle wheels, there is provided an adjusting member which is designed as a whole as a double-acting hydraulic cylinder and by means of which both the ABS and the ASR functions can be controlled. This adjusting member comprises a first piston which forms the axially movable limitation of an annular drive-pressure space coaxially surrounding the master cylinder and as a result of the pressure loading of which the master cylinder is displaceable with the effect of a brake-pressure reduction movement, and a second annular piston likewise limiting a drive-pressure space which is in the form of an annular gap and as a result of the valve-controlled connection of which to an auxiliary pressure source the piston of the master cylinder is displaceable with the effect of a brake-pressure build-up independently of an actuation of the brake unit. These two annular pistons remain in their basic positions during normal braking.

Title: Differential compensation of drive axles in rail vehicles in bends in the track with the aid of a divided wheel whose parts can be moved with respect to one another by electric motor
Inventor: GEGGERLE SIGMUND DR
IPC: B60T8/24
Filed: 1988-04-05
Abstract: In order to produce a differential compensation in the driven axles of rail vehicles in bends of tracks, a wheel which is divided into an inner segment and an outer segment is driven by the power-output side of the drive motor. With the aid of electric motors which are built into the inner segment and which engage ... via the toothed rack which is integrated in the outer segment, the outer segment is moved in relation to the inner one. Since the drive wheels can be driven from here, a relative movement of the left-hand and the right-hand drive wheel takes place which then produces the differential compensation. In addition, with this arrangement the amplitudes of the sinusoidal curves in which the vehicle moves are reduced, which contributes to protection against derailing.

Title: Hydraulically actuated folding device for an antiroll bar on agricultural tractors or similar utility vehicles
Inventor: BRONNER MATHIAS
IPC: B60R21/13
Filed: 1988-04-28
Abstract: Hitherto, folding devices with a hydraulically actuated actuation motor have only been known in conjunction with antiroll bars which do not have mechanical locking. A hydraulically locked actuation motor does not, however, fulfil the safety requirements made of it under all circumstances if it is not to be too highly overdimensioned. In conjunction with a mechanically lockable antiroll bar, the new folding device is intended to permit the said antiroll bar to be folded over from the driver's seat, in which case the driver is to be required to operate as few actuation elements as possible. For this purpose, the change in length of the actuation motor (14) which occurs with the effect of lowering the antiroll bar (1) when the actuation motor (14) is actuated is used in a first phase to unlock the antiroll bar (1) and in a second phase to lower the antiroll bar (1). As a result, only one actuation element needs to be operated in order to unlock the antiroll bar and to fold it over. <IMAGE>

Title: Spark plug with integrated ion current sensor
Inventor: SCHULTE ERASMUS DIPL PHYS DR
IPC: H01T13/22
Filed: 1988-08-23
Abstract: It is already known to detect the combustion process of an internal-combustion engine with the aid of the ion current by the use of ion-current probes. Arranging a plurality of sensors in the combustion chamber of an internal-combustion engine is, however, extremely difficult to carry out on grounds of space and because of demanding contact conditions, and, in addition, many probes are dear.   With the new spark plug, a less expensive and space-saving article is achieved which is simultaneously capable of detecting the working of the ion currents. The new spark plug is characterised in that the earth electrode is formed as the middle electrode and the trigger electrode and at least two ion-current electrodes are made in annular form and are arranged concentrically to the earth electrode. Contacting occurs, for the trigger electrode, through a central pin led out from the spark-plug shaft and, for the ion-current electrodes, through ring contacts offset axially on the spark-plug shaft. Such spark plugs find an application in motor construction, especially in motor vehicle construction.
