Title: Magnetic valve, particularly a fuel quantity control valve
Inventor: REMBOLD HELMUT
IPC: F02M51/08
Filed: 1986-02-18
Granted: 1989-08-31
Abstract: A magnetic valve, in particular a fuel metering valve for fuel injection systems of internal combustion engines, is proposed which serves to measure the injection quantity and control the instant of injection. In a valve housing, the magnetic valve has an electromagnet and a valve closing element actuated thereby, which cooperates with a fixed valve seat. To damp the opening movement of the valve closing element against a fixed stop and to keep the hydraulic forces of adhesion between the valve closing element and the stop low, a damping chamber that is open toward the valve closing element is disposed on the stop. As the valve closing element approaches, fluid is positively displaced out of the damping chamber in the form of a squish flow between the stop face and the head element of the valve closing element, so that recoiling is avoided due to thus-generated damping. As the valve closing element lifts, fluid can flow through a throttle bore or a check valve into the damping chamber, so that release of the valve closing element from the stop face can be effected with little force being exerted.

Abstract: The present invention provides a method for varying the melting points and molecular weights of polyolefins by changing the structure of the catalyst used in the polymerization. The catalysts that are useful in the present invention are chiral, stereorigid metallocene catalyst of the formula R''(C5R'm)2MeQ. The catalysts include a bridge structure between the (C5R'm) groups and may contain substituents on the groups. It has been discovered that the melting points and molecular weights of the polymers produced by such catalysts are influenced by the bridge and substituents added to the (C5R'm) groups. Thus, the present invention provides a method for varying the melting points of the polymer product and a method of varying the molecular weights of the product by changing the components and structure of the metallocene catalysts. The present invention also provides a process for polymerizing olefins in which the melting points and/or molecular weights of the product may be controlled. Also included in the invention is the discovery that the melting points of the products are controlled by the number of inversions in the xylene insoluble fraction of the polymer.

Abstract: A data block protection information code word (BSI) is formed by division of a message polymonial representing a data bit sequence (D) by a generator polynomial representing a cyclical binary code. Registers are arranged in register chains in a coder unit provided for this purpose with a polynomial ordinal number being allocated to every register representing a member of the binary code. Given the presence of a term at the ordinal corresponding to the registers (R) of the respective register chains (RK) missing in the polynomial ordinal seris, a respective logic element (V) is inserted to which an operation information is supplied, said operation information being formed in a means for the formation of the operation information (EBV) by parallel processing of a plurality of data bits together with information at the outputs of the registers (R) corresponding to the highest polynomial ordinals. As a result thereof, the processing speed of a coder unit is reduced, and thus, making possible the use of programmable or computer-controlled coder units with high speed data transmission rates.

Abstract: An adaptive depolarization-interference-compensator for a digital radio relay system using multi-level quadrature amplitude modulation (QAM) with co-channel operation of the orthogonally polarized signals which is not necessarily synchronous with the clock frequency and/or carrier frequency and produces good compensation of depolarization effects. The receiving branch of the two receivers (3, 4), which use the same RF-local oscillator (5) or separate RF-local oscillators are synchronized for the differently polarized signals and each contain a quadrature demodulator (8, 14) for two signal components (I- and Q-channel). A canceller is provided which consists of two quadrature demodulators (20, 23) for the two polarization directions, which are each supplied at with an IF-received signal of one polarization and the IF-carrier (9, 15) of the respective other polarization, and which consist of complex transversal filters (21, 22, 24, 25) (I- and Q-channel) in the signal paths to the two quadrature demodulators (20, 23). The transversal filters (21, 22, 24, 25) have their outputs coupled into the receiving branch of the respective other polarization. The delay time  tau 0 between the tappings of the transversal filters corresponds at the maximum to half the reciprocal value of the frequency of the highest spectral component of the base-band signal with a rational ratio m/n which preferably supplies a delay time which is shorter than or equal to  tau 0  (m/n=ratio of the symbol period of the interference signal to the transit time between the tappings of the transversal filter; m, n whole numbers).
