Patent DE-3718311-A1 (DE)
Title: Multiple-piston flywheel rotary pump
Inventor: KERL WERNER
IPC: F04C11/00
Filed: 1987-05-30
Abstract: The various types of pump currently in use almost all have difficulties maintaining a constant delivery rate at optimum pressure conditions in the lower range of speeds or strokes. The new multiple-piston flywheel rotary pump (MPFRP) is intended [lacuna] the entire range of delivery, and in particular solve the problems existing in the lower delivery range, thanks to its construction. The MPFRP drive shaft(s) with cylinder(s) is (are) driven by an externally flange-mounted motor; the drive shaft sets the multiple-piston flywheel in rotation. This in turn with its 2.1 double-acting pistons (crossed piston arrangement separated by the flywheel) performs about 1 1/2 different piston strokes each 90@ per revolution 4., thus providing the linear and constant delivery rate, including the necessary pressure, both in the lower and upper range of delivery rates. Due to its optimum delivery rate, simple and therefore cheap production, and easy-maintenance handling, the use of the MPFRP is appropriate wherever a constant delivery rate under constant pressure is required in the lower and indeed over the whole working range. <IMAGE>
Patent DE-3719746-A1 (DE)
Title: Integrated logic circuit
Inventor: MEYER FRITZ DR ING
IPC: H03K3/2885
Filed: 1987-06-12
Abstract: In integrated logic circuits for switching speeds in the gigahertz range, the problem is to combine the requirements for high switching speed with ease of integration by means of conventional silicon technologies. The integrated logic circuit according to the invention is based on a base-Differential amplifier preceded by a ? and the ease of integration is obtained by the fact that a double frame structure with two windows is inserted into an n-conducting epitaxial layer which is arranged on a p-conducting substrate, which windows form insulated tubs in which in each case one transistor of the differential amplifier is arranged. The metafollower transistors and passive components can be arbitrarily arranged outside the insulation tubs without additional insulation so that, in addition, very short connecting lines are obtained. <IMAGE>
Patent DE-3725003-A1 (DE)
Title: Foldable bracelet
Inventor: BIEHLER FLORIAN
IPC: A44C5/10
Filed: 1987-07-28
Abstract: A foldable bracelet made of rigid, sheet-like material is described, which consists of a strip (10) of a particular width with a central fold (11) which divides the strip longitudinally into two symmetrical halves (14), and which is subdivided into sections (12) of preferably equal length. Herringbone-like side folds (16) run from the ends of each of the sections (12) to the edges of the strip halves (14), the angle between the side folds (16) and the central fold (11) being between 45 and 80@. Further connecting folds (18), which are symmetrical in mirror image relative to the central fold, also run from the ends of the sections (12) to the ends of the strip halves, the angle between the central fold (11) and the connecting folds (18) being selected such that the end points of the connecting folds (18) from one end of a central-fold section (12) coincide with the end points of the side folds (16) which start from the other end of the same central-fold section (12). The central-fold sections (12) and the side folds (16) can be opened out from the plane in one direction, and the connecting folds (18) can be opened out from the plane in the opposite direction. <IMAGE>

Title: Measuring device for determining the peak value of high AC voltages
Inventor: MARX RAINER DIPL ING
IPC: G01R19/04
Filed: 1987-08-24
Abstract: When determining the peak value from the loading current of a measuring capacitor with the aid of a passive network in the earth conductor of the measuring capacitor, considerable measurement errors occur as a result of parasitic capacities, voltage drops in the rectifier and measuring resistor and through non-linear components such as diodes and overvoltage conductors. The novel measuring device is largely to avoid these disadvantages and to have a reduced measurement uncertainity. Use is made of an electronic measured value convertor (4) with an active current-to-voltage convertor (5) and an active rectifier circuit (6). The positive and negative peaks of the AC voltage can be determined separately by means of a zero-voltage detector (7) with a 90@ phase-shifter. With the aid of the measuring device, peak values of high AC voltages can be measured with a relative measurement uncertainity of 1*10<-4>, so that the measuring device is suitable as a standard (Fig. 1). <IMAGE>
Patent DE-3728230-A1 (DE)
Title: Circuit for detecting an incoming ringing signal in a telephone set
Inventor: KRAPP KARL-HERMANN DIPL ING
IPC: H04M19/04
Filed: 1987-08-25
Abstract: A circuit for detecting an incoming ringing signal in a telephone set is specified. The circuit contains at the input of the apparatus a series circuit composed of an isolating capacitor, a resistor and the input section of an optocoupler and of a nonlinear component. If the amplitude of the incoming signal undershoots the threshold voltage of the nonlinear component, no ringing signal is detected in a discriminator circuit on the output side, because the optocoupler does not transmit the incoming signal to its output.

Filed: 1988-02-05
Abstract: In the manufacture of blister packs of prescribed form and defined volume in a continuous operation using at least two webs of sheet, which are taken off a roll, of different material such as PVC and aluminium as the deformation and cover sheet, it is possible for a waste product to be produced which is suitable for recycling if the sealing of the cover-sheet web onto the deformation-sheet web carrying the goods to be packaged is limited to the region of the surface of the package to be divided and if, after the packs have been separated, the waste material from the deformation and cover sheet is collected separately for the purpose of recycling. This permits individual disposal and recycling of waste material of different consistency. A tool comprises a pair of tool parts (21, 22) in plate form which carry out the sealing process, of which a lower part (21) has recesses (211) for receiving the blisters (112) of the deformation sheet (11) and an upper, heatable part (22) has a fluted printing surface, the active surface (221) which comes into contact with the cover sheet (12) during sealing being limited to the surface boundaries of the blister package to be divided. <IMAGE>

Title: Read-write memory
Inventor: BUDNIK NORBERT DIPL ING
IPC: G11C8/12
Filed: 1988-07-20
Abstract: Read-write memory for digital information storage in electrical communication engineering. In known read-write memories, one memory cell is provided for storage of each bit. The memory cells are arranged in rows and columns. For writing and reading the information, only one memory cell at a time is addressed. The intention is to extend the technology of writing and reading by the new read-write memory. Optionally, all memory cells of one row or column are addressed. The data word to be written or read contains as many bits as there are memory cells in one row or column, and such a data word is written to all memory cells of a row or column, or read from the memory cells of a row, simultaneously.

Title: Method for the compaction of crops, preferably silo maize
Inventor: EGGENMUELLER ALFRED DR ING
IPC: A01D90/02
Filed: 1988-12-29
Abstract: The conveyor apparatus is designed so that the working surfaces of the conveying tools work the entire or approximately the entire cross-section of the press channel. Their action is therefore intensive, and in the case of silo maize all the grains are beaten or crushed with a high degree of probability. When known conveyor apparatuses are used, for this purpose the press channel can be moved in such a way that conveying tools work the cross-section alternately. In a conveyor apparatus with conveying tools moving into one another, a higher throughput capacity can also be achieved in addition to the working of the entire cross-section.
