Title: RLC all-pass filter circuitry - has resistor in series with capacitor in bridging path, with identical resonance frequencies for series and parallel circuits
Inventor: GOETZ GERHARD DIPL ING
IPC: H03H7/07
Filed: 1979-09-03
Abstract: The filter circuit is designed as a bridged T-circuit, having in its long branch a tapped differential transformer with a 1:1 transformation ratio. To the tap of the transformer is connected an ohmic resistor in the transverse branch. The differential transformer is bridged by a parallel resonance circuit of a coil and a capacitor. A resistor is series-connected to a capacitor in the bridging branch. The series circuit, formed by the capacitor and its lead inductance, and the parallel circuit, formed by the coil and its natural capacity, have identical resonance frequencies. Pref. a resistor is additionally incorporated in the input longitudinal branch, or a resistor is so incorporated in the output transverse branch. The various circuit elements have ratings, meeting specified equations related to the transformer inductance value, its natural capacity, its copper and iron losses, the capacity value of the parallel circuit capacitor and its natural inductance.

Title: Wind turbine and motor assembly - consists of set of small size turbines, facilitating application to various loads and can be used in low force winds
Inventor: HAMMOSER HEINZ
IPC: F03D1/02
Filed: 1979-09-10
Abstract: The wind turbine drives a power generator. Its division in smaller turbine units enables the utilisation for low force winds, which extends its utilisation period. The design provides a more uniform and quiet drive of the generator. The turbine apertures can be opened or closed by a mechanical or electrical control system, and the turbine assembly can swivel through 360 deg. The turbine diameters may be smaller and may be thus more acceptable in their environments. The suitable assembly can be easily mounted on flat roofs, or the turbines can be assembled in suitable banks for driving large power plants.

Title: Alkaline earth-contg. coal as hydrogenation feedstock - thermally pretreated to prevent carbonate deposition in preheater and reactor
Inventor: BURGBACHER GERD DIPL CHEM DR
IPC: C10G1/00
Filed: 1980-02-16
Abstract: Coal feedstock, pref. lignite, for hydrogenative liquefaction, contg. alkaline earths, is ground and if necessary dried, pref. to a water content below 20%. It is mixed with a high b.pt. hydrocarbon oil, pref. contg. oxygen cpds., and heated for 1-60 min. under pressure and at 200-450 deg.C. CO2, N2 or H2 may be present. The catalyst for the subsequent hydrogenation may be partly or wholly added before this pretreatment. The reactor deposits obtd. without pretreatment from Ca-contg. coals, esp. lignites, are chiefly calcium carbonate. The pretreatment largely converts the Ca content to CaCO3, which is ultimately removed from the hydrogenator in the reaction residues and does not deposit on reactor or preheater walls. The oil used may be e.g. a heavy oil from coal hydrogenation, a coal carbonisation oil, or a petroleum fraction.
Patent DE-3007176-A1 (DE)
Inventor: VUILLEUMIER CYRIL
IPC: G04B11/00
Filed: 1980-02-26
Abstract: A stepping motor causes a driving pinion to rotate by steps of 90 DEG , the stopping position being such that a driven pinion is blocked with a very small backlash by the pressure of a tooth of the driven pinion against the top face of one of the teeth of the driving pinion. Both pinions have simple teeth with conventional profiles capable of being cut by means of a worm-hob. The pitch of the driving pinion is between one and two times that of the driven pinion, and the layouts of the teeth are such that the arc along which a tooth of the driving pinion engages the teeth of the driven pinion includes a portion tranversed freely and a portion along which the driving pinion rotates the driven pinion by one step of its toothing.

Title: Pattern transmission system using matrix printer - uses modification such as inversion of binary components of code words for switching operations
Inventor: BORSTEL KLAUS-PETER VON DIPL I
IPC: H04L21/00
Filed: 1980-03-07
Abstract: The method as in the main patent, uses a coding system for transmitting the information, to obtain control pulses to operate the printer. A control device at the sending station is operated to change at least one code word or series of code words so as to obtain control signals for switching operation. This change may consist of an inversion of one of the binary signals of the code word. A parallel to series changeover may be used to generate a code word. At the transmitting and, a testing stage can be used to monitor the signals from the control device which may combine binary values to give a switching switching signal, which operates a changeover device to invert the signals.

Abstract: For transmitting data byte by byte between a processor (CPU) and a memory (SPE), words are formed in which the byte to be transmitted is contained a number of times. To transmit the bytes from the memory (SPE) to the processor (CPU), the desired byte is switched to a part of the data lines (DL). A byte coupler (BKL, BRK) is used for switching the byte to the remaining data lines (DL). The processor (CPU) is designed in such a manner that, for transmitting a byte from a processor (CPU) to the memory (SPE), it also outputs words in which the byte to be transmitted is contained a number of times. <IMAGE>
