Title: Method and device for dividing or slitting a rigid material to be cut, in particular wood
IPC: B26D7/08
Filed: 1986-10-17
Abstract: A method and a device serve to divide or slit a rigid material to be cut (10), in particular wood, having a modulus of elasticity preferably of about 50,000 to 400,000 kg/cm<2>. A narrow tool bearing cutting elements, in particular a circular saw blade (15), makes a gap (38) of final width in the material to be cut (10) at a cutting speed of more than about 40 m/s. To reduce the friction between the material to be cut (10) and the circular saw blade (15) and thereby lower the thermal stress on the circular saw blade (15), the material to be cut (10) is turned out away from the splitting plane (11) by means of a separating element (26) immediately after the passage of the cutting elements (Fig. 1). <IMAGE>

Patent DE-3701839-A1 (DE)
Title: Ceiling light, in particular for living and working rooms
Inventor: KALZE FRANZ JOSEF DIPL ING
IPC: F21Y103/37
Filed: 1987-01-23
Abstract: The invention relates to a ceiling light, in particular for living and working rooms, having a pot-shaped reflector, the light-emitting surface of which is circular. The reflector is bounded in the sections along the optical axis by parabola branches, the centre axes of which run at an acute angle with respect to the optical axis and intersect at the optical axis. The focal length of the parabola branches varies continuously. It decreases continuously from the median section perpendicularly with respect to the longitudinal extent of the fluorescent tubes to the median section parallel to the fluorescent tubes. At the same time, the distance between the focal points of the parabola branches increases continuously. This takes place by virtue of the fact that the point of intersection of the centre axes of the parabola branches is displaced continuously in the direction of the light-emitting direction, without its angle with respect to the optical axis changing. The changing of these positions of the points of intersection and of the focal length is coordinated such that an elliptical base area is produced in the region of the vertex of the reflector.

Patent DE-3816934-A1 (DE)
Inventor: RAMALHO-ORTIGAO JOSE FLAVIO
IPC: C12Q1/6869
Filed: 1988-05-18
Abstract: The invention includes a method and apparatus for the sequence analysis of single- and double-stranded nucleic acids on solid phase supports whereby nucleic acids for the purpose of sequencing are terminally elongated with modified nucleic acid units, which themselves serve as units for anchoring to a water insoluble and solid polymer support. In the preferred mode, modified nucleotides which are to be attached to a nucleic acid chain by chemical or enzymatically catalyzed reactions are in particular 5-bromo-2'-deoxyuridylate or in general other nucleotides halogenated or otherwise appropriately substituted at the base or sugar moieties, or streptavidin. Nucleic acids which can be immobilized in this way are either single-stranded DNA- or RNA-chains or such chains as parts of the double-stranded DNA or RNA. Water insoluble and solid supports are polymers such as cellulose, sepharose or sephadex as well as inorganic supports, in particular supports which have a backbone structure formed mainly by silicon and oxygen atoms. The water-insoluble solid supports have effector groups, in particular, they may contain immobilized antibodies specific to 5-bromo-2'-deoxyuridylate or other appropriate units capable of selective interaction with other halogenated nucleotides or nucleotides appropriately substituted at the base or sugar moieties. The binding of the nucleic acid strands which are to be sequenced to the polymer support is effected by interactions of the modified nucleotide units with the effector groups immobilized to the support, in particular by receptor ligand interactions. An apparatus is disclosed for carrying out the method.

Patent DE-3824759-A1 (DE)
Inventor: PFLUEGER ANTONIO DIPL PHYS
IPC: F24J2/40
Filed: 1988-07-21
Abstract: A solar collector for the generation of high temperatures including a tub-like housing defining a cavity, a glass plate for sealingly closing the cavity, a selective absorber and a trasparent thermal insulation structure located on the inside of the glass plate. An air gap separates the selective absorber from the glass plate. The solar collector is operated at a vacuum of less than 10000 pascal by means of a vacuum pump. The transparent thermal insulating member reduces the air convection and acts similarly to a mulitple pane for the reflected, diffuse thermal radiation. High efficiencies are thus achievable even at large temperature difference between the absorber and the area outside the solar collector. The thermal insulation effect of the air gap and at the same time of the microporous thermal insulation located in the bottom of the housing is varied by regulation of the degree of vacuum. A higher air pressure results in greater thermal losses of the absorber toward the thermal insulation member and the microporous insulation, whereby the temperature of the absorber is controllable.

Title: Process and apparatus for treating SO2-containing exhaust gases
Inventor: SPORER JOSEF DIPL ING
IPC: B01D53/14
Filed: 1988-09-14
Abstract: A process for treating SO2-containing exhaust gases is described, in which the exhaust gases are if appropriate prepurified, cooled and fed to an SO2 scrubber with a physical or chemical solvent and are then fed to subsequent solvent regeneration. In order to be able to release into the atmosphere the purified exhaust gas, complying with given air pollution values in a simple, inexpensive and space-saving manner, it is proposed that exhaust gas depleted of SO2 via the head of the SO2 scrubbing column is released directly into the atmosphere by means of a stack attachment on the scrubbing column. In this manner, the untreated gas-pure gas heat exchanger and the separate stack can be dispensed with.

Inventor: SEPP GUNTHER DR
IPC: G01S17/86
Filed: 1988-12-21
Abstract: To detect and identity individual targets, a low-flying missile has, in its ahead downwards direction seeker head, a laser rangefinder as well as an infrared sensor. After pre-adjustment the infrared sensor sweeps the area ahead and underneath, in the instructed direction, line by line in search of target-characteristic infrared radiation. On acquisition of a likely target due to one or several of the known target characteristics, the target location is determined in elevation and azimuth and held in an intermediate memory with the target coordinates. Then the likely target is automatically locked onto by the laser rangefinder whereby range shift (altitude shifts) are registered as further target characteristics. Final target recognition is then executed in a computing device according to the pre-set pattern. <IMAGE>

Title: Sales cart
Inventor: MAYR PAUL
IPC: B60P3/025
Filed: 1989-01-26
Abstract: Previously known sales carts having an underframe and a body which bears a counter, have a longitudinal wall which can be pivoted outwards by pressure cylinders. The pressure cylinders are, on the one hand, coupled to the longitudinal wall and, on the other hand, to the counter or to the floor of the body such that they run through the sales area. The sales cart designed in accordance with the invention has a sales area which is not disturbed over the entire length by any supports or pressure cylinders. This is achieved by virtue of the fact that each pressure cylinder (44) is attached at one end to the inside of the roof (28) and at the other end to the inside of the longitudinal wall (36). If the roof (28) is also of pivotable design, the pressure cylinders (44) provided there are coupled to the inside of the fixed longitudinal wall (22) and to the inside of the roof (28). <IMAGE>
