Patent DE-3012527-A1 (DE)
Title: Intelligent teleprinter group terminal - has comparator for incoming addresses and cyclically scanned station addresses of group terminal
Inventor: FIEBIG HANS-HELMUT DIPL ING
IPC: H04L12/52
Filed: 1980-03-31
Abstract: To obtain maximum terminal processing speed, the scanning of station-owned microprocessors for which no data has arrived over the main terminal buses to the connector control modules and for which therefore, no addresses are lodged at the terminal, must be avoided outgoing data if there are no data held in a particular microprocessor of the connector module. The counter (Cnt) does not dwell on such a scanning position. To do the same with respect to incoming address positions it is important that an incoming address should be detected at a moment when it already has a stable form in the connector module memory, at least a short time before the scanning memory occurs. To ensure this, the circuitry allows address comparisons to take place between addresses in the connector module (LPM) and the cyclic scanning counter addresses in such a manner that no equality but a min. difference number is the criterion for carrying out the respective sampling step. The comparator (Vg2) produces an enabling output only when the address number difference exceeds a predetermined min. value.

Title: Discharge lamp auxiliary power supply - has separate oscillator and independently powered regulation circuit providing high stability lamp voltage
Inventor: KERSCHER MAX
IPC: H05B41/298
Filed: 1980-04-15
Abstract: The power supply provides a high stability light output. The supply is driven from an AC power source, the reservoir capacitor voltage being stabilised by a single transistor acting as a switch across a non-filtered DC generator via a load inductance. The reservoir capacitor is fed from this inductance and the supply oscillator via a choke and diode the capacitor loop being completed via the transistor emitter and a series CR circuit to the generator. The stabilising transistor is controlled from a regulation circuit separately powered by a rectifier and shunt capacitors. The regulation circuit operates as a function of inputs from a potentiometer across the supply and from the supply oscillator. A diode connected in the opposite conduction sense across the transistor discharges diode and inductance self capacities.

Filed: 1980-11-19
Abstract: In a switching installation, the conductor cables (6) which support the mating contact elements (4) of the pantograph interruptor switches are deflected by the short-circuit current. In order to prevent the mating contact piece (4) being placed obliquely between the clamping jaws (10) of the contact element of the tongs of the pantograph interruptor switch as a result of this deflection, and the contact transition thus deteriorating, the mating contact piece (4) is mounted on the conductor cable (6) such that it can pivot in the horizontal direction. For this purpose, the tubular mating contact piece (4) is supported by means of its one end in a bearing (8), such that it can rotate. The rigid rod (9) which supports the bearing (8) stresses the conductor cable (6) in torsion and the other rigid rod (7), which is likewise used for the suspension of the mating contact piece (4), stresses it in bending. <IMAGE>

Patent DE-3104958-A1 (DE)
Title: Apparatus for copying originals
Inventor: MOSER ULRICH F
IPC: G03B27/74
Filed: 1981-02-12
Abstract: An apparatus for copying originals on reversal material contains an original holder, an image trap for holding the printing material, a light source for incident illumination of the originals, a lens and a reversing mirror between the original holder and image trap for projecting the original on to the printing material, as well as a photographic shutter in front of the lens. Also provided is a light-sensitive measuring cell which emits an output signal which is proportional to the quantity of incident light and controls the opening period of the shutter via a shutter speed control. In order to be able to correct the changes in light conditions which are produced in the event of change in image scale by a corresponding change in the exposure time, a reference element is mounted adjacent to the original on the original holder. The measuring cell is arranged adjacent to the image gate of the image trap and measures through the lens that quantity of light which is reflected by the reference element. The measuring cell measures in this way always only light reflected by the homogeneous reference element, as a result of which the changes in the incidence of light caused by change in the image scale are detected exactly.

Title: Awning
Inventor: KORTENKAMP WILLI
IPC: E04F10/06
Filed: 1981-03-17
Abstract: A conventional awning only constitutes a top covering. Frequently, however, a vertically running screen is required on the free edge region of the awning. In the case of the proposed structure, a profile rail, arranged on the free edge region of the covering web (5), rests, in the drawing-in direction of the covering web (5), on a carrying rail (3) in a positively locking manner. When the carrying rail (3) is extended or the covering web (5) is in the non-tensioned state, the profile rail (10) arranged on the free edge region of the covering web (5) can be easily released. This provides the possibility of once again unwinding the single winding-up roller for the covering web (5) once the carrying rail (3) has been fully extended, it then being possible to guide said single covering web (5) further downwards in a sliding manner via the carrying rail (3). <IMAGE>

Title: Method for automatic freezing of a material, in particular a biological material
Inventor: DITTRICH FRANZ DR ING
IPC: A01N1/02
Filed: 1981-06-27
Abstract: The freezer container (23) with biological material is arranged in a cooling vessel (20) on a holder device (22). A measurement probe (29) dipping into the freezer material records the temperature (T) of the freezer material. An input device (26) determines, on the basis of a preset program, desired values (T*) for the temperature of the freezer material. A control (27) delivers a control variable for a thermostat device, which regulates the temperature of the freezer material in the inside of the container by means of an adjustment of the temperature surrounding the freezer container. The thermostat device used is preferably a shifting device (24) with a controllable drive (25), the cooling vessel (20) holding liquefied gas (21) at its base and being open at the top, so that a temperature gradient is established in the cooling vessel and the temperature surrounding the freezer container (23) can be adjusted by shifting the cooling vessel into colder or warmer areas of the temperature gradient. The procedure can be monitored optically from above. According to the invention, a small tube (28) filled with protective solution is furthermore arranged on the freezer container (23), this small tube (28) protruding into colder zones of the cooling vessel (20). Crystal nuclei form in the small tube (28), by means of which the crystallisation in the freezer material is automatically triggered. The temperature of the freezer material follows the set curve, and only very slight temperature deviations occur upon crystallisation of the freezer material. <IMAGE>
