Patent DE-3131082-A1 (DE)
Title: Photographic camera having an electronically controlled diaphragm shutter
Inventor: BOROWSKI KURT ING GRAD
IPC: G03B7/16
Filed: 1981-08-06
Abstract: In the case of a diaphragm shutter, during the retarded phase of movement of the shutter opening or after termination of the phase of movement of the shutter opening, a shutter closing element is released to operate without retardation as a function of the display time value of a light-dependent control circuit. Starting from a synchronous switch (3 to 8, 17, 18) on the camera side, whose operating time (T1) can be set at least during the phase of movement of the shutter opening as a function of the exposure factor and/or as a function of the range (distance), a control connection leads to a switching stage (90, 60). Upon closure of the synchronous switch, this control connection has the effect of breaking the circuit of the shutter closing magnet (63) independently of the control signal of the exposure control circuit. <IMAGE>
Patent DE-3132254-A1 (DE)
Title: Arrangement for detecting ghost signals in a television signal
Inventor: HOLMES DAVID DUNLAP
IPC: H04N17/00
Filed: 1981-08-14
Abstract: This arrangement receives a component of the video signal as control signal, followed by an interval which can contain a ghost version of the control signal. The control signal activates a reference signal circuit (88, 76) for generating a variable search signal. A signal generator (80) responds to the search signal and generates a sequence of identification pulses. The identification pulses are compared with the video signal following in the interval after the control signal in a coincidence circuit (74) and when a ghost signal appears coincident in time with an identification pulse, a coincidence signal is output. The coincidence signal has the effect that the value of the variable search signal is stored as indication of the delay of the ghost signal compared with the control signal. During the subsequent control signal intervals, an identification pulse is only generated when the search signal reaches the value previously stored, and the phase of the identification pulse is compared with the phase of the ghost signal in order to reset the stored value to a more accurate value. When the ghost signal is lost or disappears, the arrangement returns to its initial operating mode. <IMAGE>
Patent DE-3134183-A1 (DE)
Title: Device for controlling the temperature of a heater (radiator)
Inventor: KERSTEN PETER
IPC: G05D23/24
Filed: 1981-08-28
Abstract: The invention relates to a device for controlling the temperature of a heater. This temperature control saves the exchange of the conventional, manually adjustable valve against a special thermostat valve. The control device is mounted on the heater and regulates it via the setting member (3) of the heater valve (2) to which the manual setting wheel is otherwise attached. The device has a temperature sensor (7) which can be arranged at any point of the room; furthermore, it contains a time switch (clock timer) (9) for the day/night reduction. The temperature sensor and the time switch (9) are connected to appropriate inputs of a control loop. This control loop (6) processes the signals of the temperature sensor and the time switch and outputs a control signal which drives a positioning motor (motor actuator) (5). This positioning motor adjusts the heater valve (2) as a function of the type and magnitude of the control signal. The device according to the invention is particularly suitable for older central heating systems; it permits temperature control without the need to exchange the heater valves in these central heating systems. <IMAGE>

Abstract: In the drill stand, an extension arm (14) is firmly clamped to a circular-cylindrical column (12) in a pivotable and vertically adjustable manner. A drilling-machine guide consisting of a slide (16) and a holder (18) is suspended on the extension arm (14) by means of a toothed rack. The column (12) is firmly clamped in a column base (34) inside the table (10) in such a way that it can pivot about its axis. The extension arm (14), slide (16), holder (18) and column base (34) have the same profile cross-section and are cut from the same extruded profile. This profile has a circular-cylindrical guide passage of larger diameter, which is equal to the outside diameter of the circular-cylindrical column (12) and which in the case of the holder (18) is equal to the standardised neck diameter of a drilling machine (20). The profile then also has a passage of smaller diameter, which is equal to the outside diameter of a toothed-rack carrier (22). The essential parts of the drill stand are made of extruded aluminium profiles which require no re-work so that the manufacturing costs are low and the stability is nonetheless considerable. <IMAGE>

Patent DE-3148143-A1 (DE)
Title: Developing device for electrophotographic recording materials
Inventor: KNITL PETER ING GRAD
IPC: G03G15/09
Filed: 1981-12-05
Abstract: A developing device (10) for electrophotographic recording materials (39) is indicated which preferably has a magnet roll (28) revolving in a separation sleeve (29). On the outer surface (44) of the separation sleeve, a carrier/toner mixture is retained by the magnetic field of the roll. The distance (42) between the separation sleeve (29) and the recording material (39) is selected such that the toner/carrier mixture does not touch the recording material. When the magnet roll (28) and the separation sleeve (29) are moved relative to one another, the toner particles and the carrier particles also move towards one another, whereby they are charged by the effect of triboelectricity. Charged toner particles (49) also tear off due to the movement of carrier particles and fly to the recording material (39). The developing device is suitable above all for developing processes in which a pronounced edge effect of the developed images is to be obtained. It has therefore particular advantages in electroradiography. <IMAGE>

Title: Process for the preparation of obligately methylotrophic bacteria, and plasmids and host organisms suitable therefor
Inventor: WINNACKER ERNST LUDWIG PROF
IPC: C12N15/09
Filed: 1982-06-11
Abstract: A hybrid plasmid with the replicon intrinsic to the methylotrophic bacterium is obtained from a plasmid from obligately methylotrophic bacteria, e.g. Methylomonas, on the one hand and a plasmid with selection markers on the other hand. This hybrid plasmid is - where appropriate after previous insertion of further genetic information - introduced by transformation into a host organism such as E. coli. After amplification and appropriate selection, the clones are treated with a suitable conjugative plasmid, and the mobilisability defect is eliminated by introducing another suitable plasmid. The clones obtained in this way are conjugated with plasmid-free obligately methylotrophic bateria as recipient, resulting - after selection - in clones which express proteins in accordance with the inserted genetic information.
