Inventor: WEIMANN GERHARD
IPC: E06B3/72
Filed: 1990-10-03
Abstract: A door leaf has a first flat covering element (52), a flat central element (54) arranged on the first covering element (52), at least one flat filling element (64), and a second flat covering element (56) arranged on the central element (54). Preferably, the first (52) and/or the second covering element (56) have at least one opening (58), as well as the central element (54), the filling element (64) being arranged in the opening of the central element. The openings (58) of the first and/or second covering elements are so arranged that their surfaces coincide within the surface of the opening (60) of the central element (54). Preferably, the opening (60) of the central element (54) touches the edge of the central element (54), so that the filling element (64) may be easily inserted therein. This door leaf can be rationally produced and allows various esthetic variations to be easily obtained. In case only the central element is provided with an opening, sound insulating, fire proofing or radiation shielding materials may be inserted or filled therein as required.
Patent DE-4031860-A1 (DE)
Inventor: SONDERGELD WERNER DR
IPC: G03F7/14
Filed: 1990-10-08
Abstract: In order to structure a ground metallic material surface of an impression cylinder (1) electroplated with hard chromium, a thin layer of alkali-resistant negative resist material is first applied to the metallic hard-chromium surface of the impression cylinder (1), a positive screen film is then brought into contact with the alkali-resistant negative resist layer and the latter is irradiated through the film using an ultraviolet light source. In this process, subareas of the alkali-resistant negative resist layer are cured by the light passing through the transparent parts of the film, then unirradiated parts of the negative resist layer are removed with an organic solvent developer and, finally, the hard-chromium layer uncovered after the development process is anodically hollowed out electrolytically in cup fashion through the openings of the alkali-resistant negative resist layer left behind as a network using sodium hydroxide solution. The hydroxide solution is sprayed on through a narrow iron-screen hollow cathode (9) arranged along the impression cylinder (1) at a short distance from the material surface.

Title: Appts. for screening cpds. for biocidal activity - by measuring effect on the voltage induced migration of nematodes in agar
Inventor: GUENTHER BURKHARD DR RER NAT
IPC: G01N33/18
Filed: 1991-02-28
Abstract: Appts. for screening cpds. (I) for biocidal activity is based on inducing and evaluating the forced migration of (I)-treated and untreated nematodes (pref. of the genus Rhabditis). It consists of a 30x20x12 cm (external dimensions) housing on which is a mount which can be moved forward, on rails, by a motor in 1.5mm stages. The mount carries an agar-coated glass plate (9x12 cm) which serves as the nematode migration zone and a d.c. voltage of 50V is applied to the plate. A movable (motor-driven) double arm (the lower branch carrying a light diode and the upper branch a phototransistor) scans the migrating nematodes in a serial manner (i.e. as the mount is advanced in steps). The pulse generated by detection of a nematode is passed to an electronic evaluation system consisting of an amplifier; gating circuit; coupled, monostable multivibrator to produce equal pulse lengths; pulse generating circuit (variable according to the migration distance of the nematodes); a counter; a digital 5-point display plus an output for connection to a computer. The result of the evaluation is displayed as an illuminated no. USE/ADVANTAGE - This appts. allows the degree of injury caused by (I) to be visualised and assessed rapidly. The effects of various (I) concns. can be graded.

Title: Determining filling ability of tobacco material during transit on conveyor belt - determining mass flow, conveyor speed and height profile of tobacco flow to produce volume flow and forming quotient.
Inventor: GAISSER HORST DIPL ING
IPC: G01N9/02

Title: Optical disc drive with controlled laser diode - holds intensity at stable valve by monitoring current of photodiode and adding value to reference signal to provide signal used to regulate laser diode
Inventor: SAITO YUTAKA
IPC: G11B7/126
Filed: 1992-03-26
Abstract: The optical disc drive has a lser which (9) which generates a beam focussed onto the surface. The signal is reflected back and received by a photodiode (PD) that generates a current (IM). The current is used to regulate the current (IM1) delivered by a variable resistor (VR) such that it is added to that produced by a variable current source (61). The resulting current (IM1+Iref) is converted to a voltage using an amplifier (A) and this is used to operate a drive stage (62) to control the laser diode output intensity. ADVANTAGE - Provides stable output from laser diode by exact correction of output characteristics.

Title: Converter for symmetric feeding of three-phase load - with each phase current provided with its own regulator unit
Inventor: ZOK EDMUND DIPL ING
IPC: H02J3/26
Filed: 1992-05-22
Abstract: The converter for feeding a three-phase load (4) incorporates a rectifier (1) fed from the grid, a capacitive intermediate circuit (2) and a transistorised inverse rectifier (3). The phase voltages (U1,U2,U3) formed at the output of the inverse rectifier are adjusted for its transistors by means of a pulse-width modulation control unit (5). The converter is characterised by the following facts: (a) each phase current (i1,i2,i3) is provided with its own regulator (7.1,7.2,7.3), and the same target value of the phase current can be assigned for each regulator; (b) each regulator (7.1,7.2,7.3) has a setting unit (8.1,8.2,8.3) for amplitude modulation of the corresp. phase voltage (U1,U2,U3) with the phases of these voltages set by the unit (5) at 120 deg. to one another. The three phase currents (i1,i2,i3) are equalised by adjustment of the amplitude of the associated phase voltages (U1,U2,U3). The converter is used to symmetrise the currents in three-phase magnetic stirrer, especially a continuous casting stirrer or a mould stirrer. It is used also for symmetrisation of the currents in a linear stirrer. USE/ADVANTAGE - In the metallurgical industry, for example. It allows the phase currents to be symmetrically distributed in the case of asymmetric load impedance.

Title: Sewing machine - has thread tension regulator with attached lever to feed thread at desired angle
Inventor: KUS PETER
IPC: D05B47/04
Filed: 1992-06-09
Abstract: Tension regulator device on a sewing machine is employed to eliminate the differences in pull on the thread. A disc is mounted on a bolt, with a pressure spring and adjustment. The disc is extended in a sideways direction, so that the thread goes through a fixed eyelet at the required angle. Pref. the base on the machine has a bolt fitted, on which is threaded an adjustment knob to tighten against the spring. This presses to the disc, which is designed to give an element of friction between the base and the thread, of a higher degree than that between thread and disc. A suppressor is set on the bolt, under the disc. At one side of the disc is an extension lever, so that thread coming from the supply spool direction is fed into the fixed eyelet at the angle alpha. This appliance may also perform in the reverse direction. The face of the disc is shaped to form a funnel for the thread to pass, and the tension device has sensitive adjustment. ADVANTAGE - The regulator is adaptable to current machines, is simple in operation and economical to produce. The thread tension to the machine is independent of the tension from the spool.
