Title: Device for transferring data from a microcomputer to interface components
Inventor: AUBRAM STEFAN ING GRAD
IPC: G06F12/06
Filed: 1987-02-07
Abstract: For a device for transferring data which is made available by a microcomputer to a number of slow interface components with addresses, extended addressing is required. The way this is achieved is that the unused data bits are used as address information for the interface components (D/A converters D/A 0, D/A 1, ..., D/A 7), that data and address information is written into an intermediate memory (1) by a control unit (2), and that, after the computer's write command has been removed, a signal is fed to a decoder (3) from the control unit (2), and causes the decoder to decode the address information from the intermediate memory (1) for an interface component, to address the interface component according to the result, and to release it to a component intermediate memory (D/A S0, ..., D/A S7) which is contained in it, until the control unit (2) is next addressed with a write command (WE) to write the data from the intermediate memory (1). <IMAGE>

Title: Stationary cut-off with restart device for internal combustion engines
Inventor: MANGOLDT MANFRED VON
IPC: F02B3/06
Filed: 1987-03-05
Abstract: In order, in the case of vehicles and machines with internal combustion engines, to reduce environmental pollution, fuel consumption and wear, and to increase the resale value without making operation more difficult, the engine is shut off after an adjustable period of time if the vehicle is stationary and no work is being performed. The engine is restarted by operating the clutch or brake again. This is done by means of a movement detector and, in the case of machines, further switches, by way of which a working process is indicated, and a central unit which shuts off and controls restarting. At the same time, diesel engines which hitherto had to be switched off mechanically are switched off electrically by a motor, even when switching off the ignition.

Patent DE-3740283-A1 (DE)
Title: Injection valve
Inventor: ZATECKY JOSEF DR ING
IPC: F02M61/18
Filed: 1987-11-27
Abstract: In known injection valves, the valve needles of which are provided with a conical sealing surface and the valve bodies of which are provided with a mating hollow conical seat surface, the transitions from these surfaces to the outer surfaces, adjoining in the direction of flow, of the blind hole in the valve body or of a pin on the valve needle are designed with sharp edges. The drastic cross-sectional changes thus caused bring about increased pressure losses in the fuel flow. These are to be minimised by the subject of the invention. The invention envisages, in the interior of the valve body, designing the transition from the hollow conical seat surface (7) to the hollow cylindrical wall part of the blind hole (4) in the form of a radius (8) which amounts to 0.55 to 0.65 times the blind hole diameter (9) and, on the valve needle, designing the transition from the sealing surface (11) to the outer surface (13) of the pin (12) in the form of a radius (15) which amounts to 0.65 to 0.75 times the blind hole diameter (9). The injection valve according to the invention is preferably used at very high injection pressures such as arise in large diesel engines. <IMAGE>

Title: Orientation aid for blind persons
Inventor: KOLBATZ KLAUS-PETER
IPC: G01S17/87
Filed: 1987-12-18
Abstract: The invention relates to an orientation aid for blind persons which employs a measurement beam which is emitted by a transmitter (2), which measurement beam is reflected from an obstacle or object (5) and is received by a receiver (3) and converted into acoustic signals. The transmitter (2) and receiver (3) are accommodated in a unit (1) to be worn in front of the blind person's body on a belt. It is advantageous for three infrared diodes (4) arranged vertically above one another to emit infrared beams (6, 7, 8) for the purpose of locating an object or obstacle (5) from the side of the unit facing forwards. After location, the outlines of the object (5) are scanned by a sharply focused infrared beam (10) which can be guided in a freely movable fashion along the outlines of the object. The beam (10a) reflected by the object (5) is converted by the receiver (3) into acoustic signals having different timbres (tone colours) as a measure of the corresponding distance to the object. The beams for locating and scanning the object can also be laser beams. <IMAGE>

Title: Method for producing radiator connections
Inventor: HEWING BERND
IPC: F24H9/12
Filed: 1988-02-25
Abstract: The retrospective installation of ready-made radiators in existing buildings is traditionally carried out using rigid connection pieces to produce the connection between radiator and double-strand heating tube. This requires working in a tolerance range which frequently goes beyond normal handicraft skills. The set object is to furnish a method which has greater flexibility in the production of radiator connections and facilitates the construction as a whole. This is achieved by making a vertical slot in the wall region to receive the connecting pipes before suspension of the radiators, the use of flexible connecting pipes between heating tubes and radiators, and suspension of the radiator after adaptation of this connection. This method is particularly suitable for the retrofitting of a heating installation in the renovation of old buildings. <IMAGE>
