Patent DE-2905783-A1 (DE)
Inventor: BITZER WOLFGANG DIPL ING
IPC: B41J3/28
Filed: 1979-02-15
Abstract: The output of the sequences of characters takes place with the feed of a first controlling clock generator (6) as a function of the relative movement of the write head (2) with respect to the recording medium (13), in particular in proportion to the instantaneous relative speed. Advantageously, the drive of the clock generator (6) is effected by rolling a roller (9) on the recording medium (13) and with an intermediately-connected transmission (8, 8a). As a result, virtually distortion-free characters with a uniform width and a uniform spacing can be written independently of the speed. Since positioning does not have to be determined by the characters and thus character-by-character acceleration and braking of the write head (2) and/or of the recording medium (13) is dispensed with, a large degree of transport energy can be saved. Instead of a motor-operated drive, manual guidance of the write head without degradation of printing quality is possible. Excellent quality is obtained for example when outputting characters on a column basis onto metallised paper or thermal paper by means of seven electrodes. <IMAGE>

Title: Data transmission interface between incompatible computers - has data output which is detected from one computer to control transmission cycle of different computer
IPC: H03M7/00
Filed: 1979-03-03
Abstract: A general interface technique allows information transfers to take place between different types of computers, e.g. different computers (50, 50') are linked over visual display terminals (52, 52') each screen is fitted with a read unit (64, 64') that has a matrix of light sensitive diodes (66, 66').

Title: Panic proof public emergency call box - dials automatically when alarm button is pressed and uses ultrasonic echo sounder to detect presence of caller
Inventor: SCHMIDT ARNIM ING GRAD
IPC: H04M11/04
Filed: 1979-03-30
Abstract: The emergency call box, connected to the public telephone system is esp. for road traffice use and has an alarm button, fixed microphone and loudspeaker, control circuits and an ultrasonic echo sounder to detect the presence of a caller. Pressing the alarm button closes the exchange line loop. A relay detects the loop current, irrespective of polarity, and maintains the loop after the button is released. After a short time delay, an automatic dialling circuit transmits the emergency code. When the call is answered, the dialling circuit ends the call box identification. If the alarm button is pressed again, while the echo sounder still detects prescent of the caller, the control circuit first hangs up and then repeats the call.
Patent DE-2915662-A1 (DE)
IPC: B23C3/06
Filed: 1979-04-18
Abstract: The present crankshaft milling machine comprises at least one milling unit which may be controlled in its feed advance drive by a copying mechanism operating in synchronism with the rotation of the work piece. The copying mechanism is movable back and forth along a guide extending in parallel to the longitudinal axis of the work piece along a guide. The guide for the copying mechanism defines a plane which extends substantially vertically on one side of the work piece or crankshaft and in parallel to the crankshaft axis. Each milling unit is tiltably supported on a tilting axis located below the work piece axis and extending in parallel to the work piece axis. The feed advance drive is arranged on the side of the tilting axis facing away from the work piece. The feed advance drive reaches over the work piece, whereby a closed force flow around the work piece is established and the milling forces need not be introduced into the machine bed.

Title: Memory system for music synthesiser - includes clock pulse oscillator and two analog multiplexers connected to memory by unit acting as A=D or D=A converter
Inventor: BAUMANN HANS PETER
IPC: G10H7/02
Filed: 1979-06-19
Abstract: The method of storing and reproducing electrical signals, suitable for an electronic music synthesiser, converts analog signals into digital signals for storage, then in the reading mode converts the digital signals back to analog form. Each signal emitter (10) is connected by an analog switch (11) to a multiplier (18) for entry into the memory. Two analog multiplexers (13,16) for input and output signals are connected to the memory (12) by a unit (14 or 15) which acts as an A/D or D/A converter. The analogue to digital conversion and vice versa is controlled by a clock pulse oscillator (20). During an interrogation cycle of the memory, the analogue switch concerned is controlled for a reading operation for the memory, and is multiplied with a multiplicand as a multiplier. The signal emitter is controlled for a length of time so that it is combined with an input signal so as to obtain a predetermined output signal. The outputs of the analogue multiplier (16) pass through a holding member (17) with an operational amplifier (21) and a capacitor (22) for connection to an analogue switch.

Patent DE-2937094-A1 (DE)
Title: position control for electron beam welder - uses X=rays emitted during special measurement interval by beam travelling closed path intersecting weld direction
Inventor: MOENCH CLAUSPETER DIPL PHYS
IPC: B23K15/00
Filed: 1979-09-13
Abstract: The welding process is punctuated by brief measurement intervals in which the electron beam (14) is deflected and made to trace out a closed path (22) spanning the seam (12) being welded (18,20). The beam interacts with the workpiece (10) and causes X-rays (28a) to be emitted from its surface. These X-rays are detected by X-ray detectors and the result used to control the position of the electron beams. The X-ray detector's output is a function of that length of any one section of the closed path travelled by the beam that lies between a reference position and the X-ray detector's aperture limit intersecting the closed path. The detector's aperture limit (i.e. area of measurement limit) is parallel to the feed direction (X). The associated measurement area lies on the side of the measurement area limit facing the processing zone. The detector's output is proportional to the distance between a reference axis (electron gun's axis) and the point where the closed path intersects the measurement area limit.

Title: Extracting samples from dust or water laden gas - using nozzle in flow path and matching speed by controlling flow extraction
Inventor: SEWING WALTER DIPL ING
IPC: G01N1/24
Filed: 1979-12-07
Abstract: The method and arrangement are for the extraction of a sample for analysis from a gas flow using a nozzle in the flow are esp. suitable for gas flows contg. dust and for liquid droplets. The method is easily carried out without necessitating difficult calculations or consideration of the state of condensibles in the gas. To ensure extraction of a representative sample the speed of flow of the dust and liquid laden gas in the nozzle (4) entry orifice (10) is adjusted to the flow speed of the laden gas flowing past the nozzle or vice versa. The speed matching is carried out by controlling the speed at which the partial extraction flow leaves the system. It is regulated so as to minimise the pressure difference between the two flows.

IPC: C04B22/00
Filed: 1980-01-08
Abstract: The filter is washed with rinsing water to remove solid matter, and the water is then held so that the solids settle to form a sludge, which is used as make-up water in concrete mixts. The concrete mixt. is pref. moistened with water, followed by adding the sludge to obtain a water/cement ratio (W/C) of 0.35 to 0.7. The sludge pref. contains aluminium salts and/or iron salts.
