Patent DE-4141092-A1 (DE)
Title: Filling holes bored into ground to take explosive charges - involves use of water-fed pourable filler material and net hose expandable at right angles to its longitudinal axis
Inventor: BUDAHL BURKHARD U
IPC: F42D1/08
Filed: 1991-12-13
Abstract: The dia. of the net hose in the unexpanded state is less than the dia. of the bore hole to be filled and is selected having consideration for the material expansion through pouring effect. The unexpanded net hose is filled with the filling material and then lowered into the borehole. The filling material is either bentonite or a bentonite-mineral mixt., and the filling process on the drilling unit takes place using a continuous method. The net hose is continuously formed from a netting strip. The two long edges of the netting strip are made to overlap and are joined to one another. USE/ADVANTAGE - To refill bore holes used for explosive seismic research for hydrocarbon deposits.

Title: Paper prod. cutter giving straight line cut with no paper drift - has elastic press rings for cutting blade and counter blade to take up pressure
Inventor: AIGNER MATHIAS
IPC: B26D1/24
Filed: 1992-02-04
Abstract: The cutting appts., with a rotating cutting blade (2) on a shaft (1) working with a counter blade, has an elastic press ring (24) along the cutting edge (23) for support, or at its blade shaft (1). Its dia. is at least equal to the dia. of the cutting blade at its cutting edge, with a sprung action on loading towards the shaft (1). In the cutting position of the blade, the press ring (24) lies on a cylindrical section of the counter blade (3), directly near its cutting edge (33), and under pressure. In an unstressed condition, the dia. of the press ring (24) is slightly larger than the dia. of the cutting edge (23) of the cutting blade (2). A 2nd elastic press ring can be fitted to the counter blade (3) which, when not under load, has a dia. at least equal to the dia. of the counter blade (3). It faces the press ring (24) of the cutting blade (2), and is in contact with it in the cutting position. A 3rd elastic press ring can be fitted to the other side of the cutting blade (2) with a dia., when not under load, at least equal to the cutting blade dia. In the cutting position, it lies under pressure at the circumference surface of a pressure disc in front of the counter blade, which has a smaller dia. than the counter blade where they are together. USE/ADVANTAGE - The assembly is for cutting paper prods. such as pamphlets or magazines or blocks of paper held between conveyor belts, to guillotine the edges with a rotary cutting blade. The assembly gives a cut with a straight line without any paper drifting during the cutting action.

IPC: F03G3/00
Filed: 1992-03-11
Abstract: A centrifugal drive with guided centrifugal masses (2) is characterized by a continuous figure-of-eight track (1) with two track loops connected by straight connecting sections.

Title: Optical control of closed space, e.g. of furnace contg. material charged atmosphere - using inspection glass closing sight opening in wall enclosing space with inside surface of inspection glass acted on by rinsing gas
Inventor: ROELING DIETER
IPC: G01N21/15
Filed: 1992-06-16
Abstract: The gas rinsing is carried out in such a way that a gas zone is created behind the inspection glass (3). This prevents a material separation in solid and/or liquid form at the surface of the inspection glass, depending on the temp. of the inspection glass. The control results at intervals, and the rinsing gas inlet is automatically interrupted between the control intervals and the sight opening (2) is closed on the space side. The system for carrying out the optical monitoring of the enclosed space includes a rinsing gas line (4). This line opens out in the sight opening (2) at a small distance from the space side surface of the inspection glass (3). The sight opening can be closed with a separating unit (5), which has a controllable operating unit (9). The rinsing gas line (4) has a variable shut-off unit (6). ADVANTAGE - Avoids contamination of inspection glass as far as possible and necessary cleaning frequency reduced.

Title: Selective optical display or marking of given atoms or mols. - uses electron flow between micro point and sample for detection to give an image signal
Inventor: ZIMMERMANN HARTMUT DR RER NAT
IPC: G01N21/66
Filed: 1992-10-02
Abstract: For the selective optical display and marking of given atoms, mols. or mol. gps. by fluorescence in a sample, a grid tunnel microscope or similar appts. is used. A micropoint gives a surface gridding at the sample surface or at the sample on a substrate. The fluorescence of the given atoms, mols. or mol. groups is energised by an electron flow between the points and the sample, to be identified by an image and/or detection system, as a signal to form an image. Pref. the image signal is transferred as part of an image, according to the location of the micropoint or to assemble the geometrical position or coordinate data to be held in memory, for a control signal to position the point. The voltage between the micropoint and the sample is increased to energise the fluorescence by an electron flow between the micropoint and the sample. USE/ADVANTAGE - The method is for the study of mol. structures or part-structures, for optical identification and marking especially to give DNA sequences. The system gives an improved geometrical resolution and localising of separate sequences.

Patent DE-4239121-A1 (DE)
Inventor: HAN GYO-JIN
IPC: G11C11/409
Filed: 1992-11-20
Abstract: A bit line control circuit performs a sensing operation of memory cell data in a semiconductor memory device. The circuit includes a precharge circuit M1, M2, an equalizing circuit M5 and a sensing acceleration circuit M3, M4 each comprising the same type of MOS transistor. Since a charge sharing operation of the sensing acceleration circuit M3, M4 is disabled during a read operation, a write operation is performed at high speed and the generation of direct current is suppressed. Further, the area occupied by transistors is reduced, producing the desirable result of a highly integrated semiconductor memory device. <IMAGE>
