Title: Two-piston rotary actuating mechanism - has outer cylinder chambers connected to common pipe with pressure-relief valve
Inventor: LOHE BERNHARD
IPC: F15B15/08
Filed: 1980-12-16
Abstract: The rotary actuating mechanism has two pistons working in a single cylinder, and each with a rack meshing with a common pinion on an output shaft. The chamber between the pistons and containing the racks and pinion is connected to a pipe supplying a medium under pressure moving the pistons outwards, while springs acting against their crowns thrust them back inwards again. The two cylinder chambers (9,10) formed by the piston crowns are connected to a common pipe (16), to which a pressure-relief valve (17), discharging to atmosphere, is in turn connected. In the supply pipe (12,14) to the central chamber (8) there is a changeover valve (13), also connected to the common pipe. When pressure is applied to the first part of the supply pipe (12), this causes the valve to connect it to the central chamber and shut off the connection to the common pipe. When there is no pressure in the supply pipe the pressure is generated in the second part (14) by the springs (11), the second part and the common pipe are connected together and the connection to the first part (12) is shut off.

Patent DE-3116262-A1 (DE)
Inventor: EBERHARDT KURT DIPL ING
IPC: H04M1/76
Filed: 1981-04-24
Abstract: To control the earphone and microphone amplifiers as well as the balancing network of a subscriber's telephone terminal which is fed, through a subscriber line in communication systems, to the effect that the attenuations in subscriber lines of unequal lengths do not affect the transmission characteristics between the exchange and the subscriber, a circuit arrangement is provided for producing the necessary control function, which is simple, integratable and has minimum tolerances. Above a predetermined threshold value, a voltage proportional to the line current variations controls the emitter-to-base junction of two grounded-base transistors at the collectors of which the control current is available. The control currents produce their effect on the negative feedback of the microphone and the earphone amplifiers. An increasing line current causes the cotrol current to decrease, thereby effecting a stronger feedback and a reduced amplification. Further, the voltage proportional to the line current variations and available at the emitter resistor of another transistor, controls the balancing impedance through a current mirror, to attenuate the sidetone independently of the length of the subscriber line.

Title: Raster plate for producing a copy from a transparency with a high contrast range on a copy carrier having a normal gradation
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G03C5/08
Filed: 1981-09-12
Abstract: A raster plate for producing a copy from a transparency having a high contrast range on a copy carrier having normal gradation with reduction in contrast is proposed. This plate is to be used for matching the gradation of conventional instant-photo material to projected individual images of a super-8 film and to be produced particularly inexpensively and simply in high numbers. To achieve this object, the raster plate consists of a transparent carrier (1), one surface (1a) of which is constructed as a crossed-lens raster. The side edges of the square raster elements (2a, 2b) extend at an angle of 45 DEG  with respect to the side edges of the rectangular raster plate. The planar side of the raster plate is provided with filter layers for colour filtering and partial attenuation of the light incident on the raster plate. The surfaces of the plate are suitably antireflection-coated and astatically coated. <IMAGE>
Patent DE-3139381-A1 (DE)
Title: Adhesive pump
Inventor: JOERSS NORBERT
IPC: F04B15/02
Filed: 1981-10-03
Abstract: In the case of an adhesive pump, particularly for labelling machines, the adhesive feed pump is arranged in a pump pipe not conveying adhesive; the adhesive is fed to the adhesive outlet point by way of a second adhesive-carrying riser pipe, which is connected to the first pipe and runs parallel to this. The riser pipe accommodates an elongated heating cartridge, which extends up to the adhesive outlet point. On the adhesive outlet point a temperature sensor device is provided which measures the temperature of the adhesive directly at the delivery point and relays each change in temperature to a switching device, particularly a switching transistor, which acts on a control circuit so that the heating cartridge is heated more strongly if the temperature is too low and less strongly if the temperature is too high. In this way the temperature of the adhesive at the outlet point is kept at a largely constant temperature. In order to prevent overheating of the adhesive in the riser pipe in the event of a failure of the compressed air, a pneumatic switch is connected into the compressed air line for operation of the piston, which in the event of a failure of the compressed air gives a signal to the control device and switches off the power supply to the heating cartridge.

Title: 2-level motorway
Inventor: ACHENBACH FRIEDBERT
IPC: E01C1/00
Filed: 1981-12-01
Abstract: Level 1: three-lane carriageway of conventional construction with crash barriers. Level 2: three-lane carriageway for the opposing traffic, resting on concrete columns and bounded by railings. The roofing is designed with solar cells and glass elements, likewise resting on concrete columns. Shifting the opposing carriageway to the 2nd level reduces the area required in comparison with parallel carriageways with opposing traffic at the same level. The result is a reduction in the risk of accidents occurring and dry carriageways all year round. The solar cells used in the roofing serve to provide energy. The glass elements improve the light conditions at level 2, see also the enclosed drawing. <IMAGE>

Title: Measuring instrument for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground
Inventor: HUEBNER HANS-JOERG DIPL KFM
IPC: G01W1/04
Filed: 1982-05-12
Abstract: In a measuring instrument (10) for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground, comprising a current source (21), a measuring arrangement (22), an operating unit (23) and a display unit (27), written recordings and, particularly underground, the keeping and carrying of an air log can be dispensed with since a memory unit (13) for storing the measurement values of the respective characteristic quantity is provided and connected to the measuring arrangement (22). Measurement values stored in the memory unit (13) can be transmitted to a central processor in which they are then evaluated, but a pre-evaluation, for example a normalisation of the measurement values, is also possible in the measuring instrument (10) itself, via a normalising stage (25). <IMAGE>

Title: Collection container for lost ink in ink jet printing mechanisms
Inventor: MARTENS HORST
IPC: B41J2/17
Filed: 1982-06-01
Abstract: In ink jet printing mechanisms having ink jet matrix print heads (33), the supply system and the print head (33) are rinsed with ink at intervals in time, the ink droplets ejected from outlet nozzles (31) of the print head (33) being sprayed into a collection container (19). This ensures that the ink does not dry in the outlet nozzles (31), and that the first character to be represented is depicted satisfactorily, even after relatively long waiting times. In known arrangements, the lost ink is absorbed by a pad which has to be exchanged separately from the ink supply container. It is impossible to carry out this exchange without soiling the fingers. The invention is based on the object of providing a collection container (19) for lost ink in ink jet printing mechanisms, which container allows simple exchange and reliably avoids soiling of machine parts by lost ink. For this purpose, the collection container (19) has a protective housing (21), which is closed on all sides and in whose hollow space (23) an absorbent material (25) is accommodated, an opening (27) in one end wall (29) of the protective housing (21) for the passage of the lost ink droplets, and an elastic part (35) of the absorbent material (25) below the opening (27), as a result of which any undesired material adhering to the front face (37) of the print head (33) can be wiped off. Soiling of the operator's fingers when exchanging the collection container (19) and of machine parts is reliably avoided. <IMAGE>
