Title: Device for setting a daisywheel to a zero-position bit pattern of a motor in a typewriter or office machine of similar design
Inventor: GERKEN HEINER DIPL ING
IPC: B41J1/24
Filed: 1985-10-25
Abstract: In program-controlled typewriters or office machines of similar design, it is necessary for the daisywheel (5) to assume a particular position relative to the bit pattern driving the stepping motor (7) at the beginning of the printing operation. Only in this way is precise setting of the daisywheel (5) always guaranteed. The invention is based on the object of providing a device which is easy to manufacture, to assemble and to adjust for setting a daisywheel, which can be driven stepwise by a motor, to a zero-position bit pattern of the motor. This object is achieved in that a blocking member is arranged on the type carrier carriage (4), which blocking member can be moved, during the movement of the carriage (4) into an edge position located outside its operating range, into the blocking position by a stop (30), arranged so that it can be set in its direction of movement, for blocking the daisywheel (5) which can be driven by a motor (7). The setting device according to the invention allows simple and rapid setting of the daisywheel to the zero-position bit pattern of the motor. The individual parts used are also easily adjustable to compensate for production tolerances. <IMAGE>
Patent DE-3541935-A1 (DE)
Title: Method and device for reproducing at least one adjustment parameter of a medical image device
Inventor: BUCHNER KLAUS DIPL ING
IPC: G06K19/08
Filed: 1985-11-27
Abstract: The adjustment parameters of the image device (1) used during the generation of a patient image, for example the transmitting power or the receiving gain, are picked up as parameter signals (Sp) and transmitted to an information carrier (33). The parameter signals (Sp) are allocated to the patient image derived from any signals (SB) and recorded. After an arbitrary time, the stored parameter signals (Sp) are read out of the information carrier (33) and transmitted to the adjustment input (7) for the adjustment parameters. The image device (1) then automatically sets itself in accordance with the parameter signals (Sp) read out. The relevant parameter signal (Sp) can be, apart from the transmit level and the receive gain, for example also the depth of focus in the case of an ultrasonic device (1); it can also represent patient data such as size, identification number, weight and so forth. It is advantageous that a high accuracy can be achieved in adjusting the device parameter(s) whilst saving a considerable amount of time. <IMAGE>
Patent DE-3544724-A1 (DE)
Title: Tank arrangement for an operating liquid of an internal combustion engine
Inventor: ARENS GUENTHER DIPL ING
IPC: B60K15/077
Filed: 1985-12-18
Abstract: In order to avoid unwanted flow conditions in a tank arrangement for fuel or oil, containing two tanks (1, 2), which a suction pump delivers into an internal combustion engine, the two tanks are connected close to the base by way of lines (3, 4) and in their upper areas by way of a venting line (8). Only the tank (1) connected to the intake side of the pump has a connection to the atmosphere. The opening of the venting line (8) into it is so situated that if the tank arrangement (1, 2) is inclined, any exchange of liquid between the two tanks (1, 2) is virtually prevented. By appropriate selection of the flow cross section of at least one of the lines (3, 4) close to the base with reference to the change in the viscosity of the liquid as a function of the temperature, it is ensured that when the engine is cold, the storage tank (2) lies virtually outside the liquid circuit (fig. 1). <IMAGE>

Patent DE-3618465-A1 (DE)
Inventor: ROTHERT REINHARDT
IPC: C12M1/14
Filed: 1986-06-02
Abstract: A process for reacting substrates with biocatalysts in a two-phase liquid system disposed in a columnar vessel having a top portion with an exit opening and a first filter disposed therein, a bottom portion with an entrance opening and a second filter disposed therein, a feed line connecting the exit and entrance openings, and a pump disposed in the feed line. The process comprises the steps of: stirring the two-phase liquid in the columnar vessel to accelerate sedimentation and minimize accumulation of the biocatalysts in the top portion of the vessel; selectively controlling the temperature of the two-phase liquid within the vessel; drawing, with the pump, a portion of the two-phase liquid through the exit opening and first filter; and passing the drawn-off portion of the two-phase liquid through the feed line and through the entrance opening and second filter into the vessel to enhance miscibility of the individual phases of the two-phase liquid with the vessel.

Title: Apparatus for the drying of large-surface material
IPC: D06F58/26
Filed: 1986-11-17
Abstract: The drier is suitable for the drying of laundry, paper, fruit, film negatives and the like. The heating takes place by means of thermal energy, for example with warm water from a heating circuit. In the drying of laundry, the garments to be dried are suspended in a drying space and are dried by drying air previously conducted via ribbed heating bodies through which warm water flows. The system contains no moved parts, with the exception of the waste-air blower. A careful treatment of the material to be dried is thereby achieved. Furthermore, the energy costs are reduced to less than 1/3, with the result that particularly economic operation is to be expected. <IMAGE>

Patent DE-3700421-A1 (DE)
Inventor: FAEHNRICH HANS-JUERGEN DIPL IN
IPC: H05B41/298
Filed: 1987-01-08
Abstract: In a circuit arrangement for the high-frequency operation of a low- pressure discharge lamp (LP1) with a push-pull frequency generator (3), a smoothing capacitor (C4) and an active harmonic filter (5), a switch-off device with a fast trigger circuit is provided. The trigger circuit consists of one or more series-connected Zener diodes (DZ1, DZ2), which connect the gate of the switch-off thyristor (TH) to the positive pin of the smoothing capacitor (C4). In addition, the trigger circuit contains a resistor (R9), which connects the gate of the switch-off thyristor (TH) to its cathode. If the low-pressure discharge lamp (LP1) fails, the trigger circuit ensures that the switch-off thyristor (TH) is switched-through within a few milliseconds and thus inhibits operation of the circuit arrangement. Destruction of the smoothing capacitor (C4) by the pumping operation of the active harmonic filter (5) is thus prevented. <IMAGE>
Patent DE-3700606-A1 (DE)
Title: Process for the preparation of alkyl n-butyl ether
Inventor: SIGG REINHARD DR
IPC: C07C41/20
Filed: 1987-01-10
Abstract: Until now, alkyl n-butyl ether was prepared by laboratory processes, for example by hydrogenation of 1-ethoxybut-2-yne on PtO2 in glacial acetic acid. The conversion of this laboratory process to an industrial process presents great difficulties because of the risk of corrosion and would only be possible with great technical outlay. A Pd supported catalyst is used in the preparation of alkyl n-butyl ether by catalytic hydrogenation of 1-alkoxy but-1-ene-3-yne. The hydrogenation is preferably carried out in the presence of a solvent, such as e.g. ethanol. The process can be carried out on a large scale without difficulty. The alkyl n-butyl ether is obtained with complete conversion in virtually quantitative yield.
