Title: Remote control system with an actuating device arranged on a steering wheel
Inventor: HAYASHI CHIKAHISA
IPC: B62D1/04
Filed: 1984-02-03
Abstract: In a remote control system, provided, in particular, for motor vehicles, with an actuating device arranged on the steering wheel, a time-serial pulse signal is used as actuating signal. A single signal line is used for sending the actuating signal to a receiving device arranged on the vehicle chassis, which decodes the time-serial pulse actuating signal and controls, as determined by the decoded signal, a voltage supply for a load which is defined by the time-serial pulse actuating signal. A dialogue function can be provided in the receiving device with the aid of which the time-serial pulse actuating signal input can be confirmed so that the voltage supply can be controlled for the correct load with higher accuracy and reliability. The remote control system can carry out several remote control operations in a simple and reliable manner with the aid of only a single signal line which connects the actuating device to the receiving device.

Title: Mixing machine
Inventor: HAMMANN HEINZ
IPC: B01F7/16
Filed: 1984-02-10
Abstract: The invention relates to a mixing machine having two synchronously rotating mixing tool sets, and a further mixing tool set which is arranged at a distance above the overlapping region of the first-mentioned mixing tool sets, and which are driven in a contrarotating manner about the central, vertical central axis, by a transmission which is conceived in such a way that the plane of rotation of the mixing tool support, as well as other essential transmission parts, but especially all the sealing elements affected by the material to be mixed, are arranged above the required transmission lubricant level, so that in the case of failure of a sealing element it is absolutely certain that no transmission lubricant can get into the mixture. Likewise, a defective sealing element can be replaced without the otherwise inevitable complete dismantling and stripping of the transmission. This transmission design takes full account of the indispensable operation-specific requirements in chemistry and in the food and feedstuffs industry, which considerably extends the range of applications of such mixing machines.

Title: Combustion engine with direct injection
Inventor: MATSUI YUKIO
IPC: F02B23/06
Filed: 1984-05-05
Abstract: The present invention relates to a modified Saurer direct injection diesel engine, the injection nozzle being offset to one side of the cylinder bore axis and a lip being provided around the upper circumference of the recess, which generates a sufficiently powerful quenching swirl and counter quenching swirl to entrain and disperse (that is to macro-mix) the fuel, which is injected along the shortened injection paths, and to prevent wetting of the recess wall. Furthermore the lip is so arranged that it allows the finely dispersed fuel droplets with low mass moment of inertia and low kinetic energy (micro-mixed) of the fuel, which is injected along the long injection paths, to be drawn out of the recess under the influence of the counter quenching swirl, thereby preventing any delay in the combustion.

Title: Retainer film caps for dental purposes
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61C5/77
Filed: 1985-04-23
Abstract: In order to obtain a gap for accommodation of the fixing cement, deliberate overdimensioning of the dental replacement is necessary. This can be achieved by appropriate enlargement of the dental model stump by so-called retainers. The retainer film caps according to the invention are pre-shaped of an elastic, thermoplastic or shrinkable material with various, defined layer thicknesses (D1). The dimensions correspond approximately to the conventional dimensions of prepared teeth. In a preferred embodiment, retainer caps (1) are designed such that they are inverted over the dental model stump (2), are shrunk onto the stump by means of hot air and can be shortened, if required. The caps can be used on any model stump material. Depending on the production method of the dental replacement, the dimensions of the dental model stump can be increased by means of the retainer caps with a uniform layer thickness on all sides, so that restoration with the desired overdimensioning is possible. <IMAGE>

Title: Short-circuit-resistant transistor output stage
Inventor: HILL HEIDEBRECHT
IPC: H03K17/082
Filed: 1985-04-26
Abstract: A short-circuit-resistant transistor output stage is proposed, whose drive circuit monitors the output current and, possibly, switches off the output transistor (T1). The output transistor (T1) is switched on and off as a function of a capacitor voltage (UC) which is reduced in the event of an excessive output current via a low-value resistor (R4) and is otherwise increased via a high-value resistor (R3). The use of the proposed transistor output stage results in constant repetition times and switching-on times in short-circuit operation, over very large temperature and supply-voltage ranges. <IMAGE>

Title: Process and device for generating patterned or marbled layers
Inventor: BURMESTER ECKHARDT
IPC: B29C48/08
Filed: 1985-05-17
Abstract: The invention relates to processes and devices for generating patterned or marbled layers by merging at least two melt streams (A, B) of different composition and preferably consisting of thermoplastic. The degree of mixing of the different melt streams (A, B) and therefore the influencing of the resulting patterning or marbling is caused by a separating wall (3) which can be deformed by the pressure of the individual melt streams (A, B), the degree of deformation of the separating wall (3) determining the mass flow of the individual melt streams. The separating wall (3) has an irregular edge profile. Patternings or marblings which are not exactly identical can thus be produced in a simple manner by means of the pressure control of the melt streams which changes with time. <IMAGE>
