Patent DE-3740482-A1 (DE)
Title: Circuit arrangement for monitoring a plurality of power outputs connected in parallel
Inventor: STEINMANN HELMUT DIPL ING
IPC: H02H5/10
Filed: 1987-11-28
Abstract: In a circuit arrangement for monitoring a plurality of power outputs connected in parallel, to achieve a cost-effective monitoring circuit having low losses, all power outputs (11-14) are led via a common measuring resistor (30). A flip-flop (28) is set by means of each starting pulse for the power outputs (11-14). A comparator (28) compares the measured voltage (UM) fallin at the measuring resistor (30) with a reference voltage (Uref1) and generates a reset pulse for the flip-flop (28), as soon as the measured voltage (UM) exceeds the reference voltage (Uref1). The output potential of the flip-flop (28) effects the closing or opening of an electronic switch (31) in series with the measuring resistor (30) and is continuously evaluated to detect short circuits. The flip-flop and the comparator are advantageously formed by a comparator (28) (Fig. 1). <IMAGE>

Patent DE-3802450-A1 (DE)
Inventor: BRINCKMANN WILLI DIPL ING
IPC: G01S3/78
Filed: 1988-01-28
Abstract: To determine the direction of incidence of optical radiation, a device is used in which a photodiode array (DA) comprising a multiplicity of closely adjacent photodiodes (D1 to Dn) arranged in rows is located transversely to a slotted diaphragm in an otherwise lightproof housing. From the single of a photocell (D1 to Dn) illuminated through the slotted diaphragm, the direction in which the radiation source is located can be inferred. 
<??>The intensity of the optical radiation to be detected varies within a wide range. The proportion of parasitic radiation which is registered by the photodiodes (D1 to Dn) increases with increasing intensity. In order to eliminate this parasitic radiation from an analysis, the photodiodes (D1 to Dn) are followed by analog comparators (K1 to Kn) with variable reference voltage (Uref1). The reference voltage (Uref1) is corrected by an analog comparator (Kz1) proportionally to the intensity of the radiation to be detected, determined by a central photodiode (Dz).

Abstract: In order to produce simultaneously a plurality of parallel kerfs in a workpiece, a plurality of circular-disc-shaped tool blades (1) are fixed on a driveshaft (2) at mutual distances by means of spacer rings (3') in such a way as to be fixed in terms of rotation and exchangeable. In order to be able to compensate for thermally induced expansions of the outer rim of the tool blades (1), the latter are subdivided by radial slots (4) into a plurality of sectors. The driveshaft (2) is equipped with a number of elevations (8) of spiral outer contour corresponding to the number of sectors. Seated on these elevations (8) are shoes (9) acting as clamping wedges. The wedge angles are chosen such that the wedge connection can be loosened by itself. The shoes (9) are wider than the tool blade (1) and are each provided with a groove at the outside. Inserted into these grooves are semicircular projections (10) of the inner opening (5) of the tool blade (1). As a result, the tool blade (1) is laterally held in the centre region. In addition, the spacer rings (3') lie on both sides of each tool blade (1) without hindering its radial and tangential relative movements. The spacer rings (3') are fixed on the driveshaft (2) with the aid of radial spokes (11) in such a way as to be fixed in terms of rotation but exchangeable. Those surfaces of the spacer rings (3') adjacent to the tool blades (1) are ... with a vibration-damping coating (13), ... Original abstract incomplete. <IMAGE>

Title: Purification of the enzyme cellulase
Inventor: HEITSCH JUERGEN
IPC: C12N9/42
Filed: 1988-06-05
Abstract: The enzyme cellulase is available as crude product from fungus cultures with numerous additional activities and concomitant substances. Purification has been attempted several times with chromatographing methods and precipitants. The results are imperfect, often difficult to reproduce and, especially in the case of chromatographic methods, can rarely be achieved without considerable expenditure. The novel method is simple, always reproducible, eliminates the additional activities to insignificant residues and affords high yields with minimal expenditure. The principle of the method is a selectively insolubilising precipitation of the additional activities which leaves the coprecipitating enzyme cellulase in active form. The agent used for this is a mixture of the compounds resorcinol, sodium tribromoacetate and phenol. After this, the purified enzyme can be extracted from the precipitate. The purified enzyme degrades both amorphous and crystalline cellulose as far as glucose.

Title: Barrier fence for garden beds or garden installations, for preventing slugs and snails climbing over
Inventor: MURAWSKI HEINRICH
IPC: A01G13/10
Filed: 1988-10-20
Abstract: In the case of known barrier fences, two metallic conductor track strips which are parallel and at a distance from one another are continuously connected to a low-impedance, low-voltage source, so that, as a result of their slow reaction and the long-term excitation applied to them, slugs and snails which creep over them cannot become free and are killed. The invention avoids the disadvantage occurring in this case that the slugs and snails which stick to the fence emit secretion and thus form a low-impedance electrical short, the metallic conductor tracks being electrolytically decomposed and destroyed. In order to keep the electrolytic decomposition of the conductor tracks of the barrier fence as low as possible and thus to make its service life as long as possible, the conductor tracks (7, 8) of the barrier fence have a pulsed voltage applied to them at a pulse repetition frequency and duty ratio which are so low that the excitation applied to the slugs and snails has no paralysing effect, allowing them time to move back, and does not lead to excessively large emission of secretion. Garden beds and garden installations. <IMAGE>

Title: Method of sealing base surfaces, preferably of existing landfill sites or contaminated surfaces
Inventor: GAISER HERBERT
IPC: E02D31/00
Filed: 1988-12-08
Abstract: To seal base surfaces, preferably of existing landfill sites or of contaminated surfaces, pipes or rods are progressively drawn in under the surfaces parallel to one another at a distance apart. A shield is moved up with the pipes or rods or with tension elements laid through the pipes. Sheets lying side by side are drawn in between the layers separated by the shield. In the process, the sheet drawn in last in each case engages in a sealing manner in a lock-like guide of the sheet drawn in beforehand. In order to avoid tearing of the drawn-in sheets in their connecting area, tension means are drawn in by pulling first of all two of the pipes drawn in beforehand, which tension means are hung on these pipes. The shield is then moved up by pulling these tension means. Tension means are in turn hung on the shield. A material supporting the boundary layers which are separated by the shield against one another and increasing the sliding ability is ejected from the shield. Further tension means hung on the shield are tightened by it. In a final operation, a shield on which the sheet to be drawn in in each case is hung is again drawn through with the tension means drawn in by the shield.

Title: Process for the production of a diaphragm made of fully carbon-containing materials for an acoustic unit
Inventor: ODAJIMA HIDEO
IPC: C04B35/532
Filed: 1989-03-09
Abstract: A process for the production of a diaphragm made from fully carbon-containing materials for an acoustic unit which comprises the steps of mixing and compounding an organic composition which contains one or more mixtures of monomer, prepolymer and lower polymer of a relatively simple, polymerisable, heat-curable resin of a substance which has a high residual carbon content after calcination, with carbon powders as binder, preparative shaping of the same to give a film or sheet form, calcination of a diaphragm shape which has been shaped to a desired diaphragm structure, and of a moving coil element shape which has been shaped to a desired moving coil structure from the film or sheet shape, and subsequently forming an integrated structure of the diaphragm and the moving coil element by calcination of a composite material which [lacuna] with the diaphragm shape and the moving coil element shape via an organic liquid composition which has a high residual carbon content, the steps being carried out in an inert-gas atmosphere. This enables the process to transmit a drive force produced in a moving coil onto the diaphragm without loss, without fatigue phenomena, such as creep of the materials, independently of the external ambient conditions.

Title: Hydraulic motor drive for engine cooling fan - has valve which increases pressure on motor gears with increasing speed
Inventor: RUSTIGE HAYNO DIPL ING
IPC: F04C15/00
Filed: 1989-06-19
Abstract: The cooling fan of an IC engine is driven by a hydraulic motor (14) which is supplied with oil from a pump (10).  The hydraulic motor (14) is of the gear tooth type and has a pressure plate (46) pressed against one side of the pair of gears. The pressure (Ps) exerted on the pressure plate (46) is due to oil supplied through a throttling orifice (19) from the pump (10).  The oil supply pipe (16) is connected to a valve (17) which is normally held open by a spring (25).  As the engine speed increases the oil pressure in the pipe (16) increases and overcomes the spring pressure and closes the valve (17). The pressure on the pressure plate (46) is then increased so that it equals the delivery pressure of the pump (10). USE - Hydrostatic drive for engine cooling fan.
