Title: Dichtung fuer fluidische arbeitszylinder und kolbenlaengsschieberventile
Inventor: SCHNEIDER GOTTFRIED
IPC: F16J15/32
Filed: 1989-12-19
Abstract: Die Erfindung beinhaltet eine Dichtung fuer fluidische, insbesondere pneumatische, Arbeitszylinder und Kolbenlaengsschieberventile, die in Maschinen und Automaten zur Anwendung kommen. Die Dichtung besitzt einen schlauchfoermigen Querschnitt, der eine unterschiedliche Geometrie aufweisen kann und besitzt an der Dichtflaeche zum Reibpartner eine aus OEffnungen fuer die Luftbeaufschlagung gebildete Perforation, wobei die Breite der Perforationsoeffnungen geringer ist als die der effektiven Dichtflaeche. Die Dichtung kann als Schmierstoffdeponie genutzt werden. Wegen der geringen Dichtungsvorspannung ist die Startreibungskraft gering. Mit der Druckbeaufschlagung bildet sich auf jeweils einer Seite eine stabile Dichtflaeche heraus. Die Dichtung kann so ausgefuehrt werden, dasz sie entweder am Kolben oder im Zylindergehaeuse verlagert ist.

Abstract: A hydrostatic drive for standard units with multi-axle drive, with at least one hydraulic source, at least two hydraulic motors or groups of hydraulic motors connected in parallel and a mechanical connection with a transmission ratio (i) between each hydraulic motor and the axle driven by the respective hydraulic motor, in which each of the hydraulic motors or each group of hydraulic motors respectively drives one or more axles, at least some of the driven axles can be uncoupled from the hydraulic motor(s) driving them and the torque constants (k) of the hydraulic motors driving the standard units are essentially equal at maximum capacity, the torque constant (k) corresponding to the output torque on the shaft of the hydraulic motor at maximum capacity and a pressure differential of 1 bar, is, as a purely hydrostatic drive and control arrangement, to be capable of permitting a high torque on the one hand and a high axle speed on the other for a comparatively low weight of the axle drive. This object is achieved in that, allowing for the diameter, the transmission ratios of the mechanical connections are different from one another for at least some of the driven axles, so that at least for these driven axles the respective product of the torque constant of each hydraulic motor or each group of hydraulic motors and the transmission ratio of the associated mechanical connection (k x i) is different. <IMAGE>

Filed: 1995-10-30
Granted: 1997-07-01
Abstract: The invention relates to the field of thermal engines. The use of water vapour mixed with a fuel additive would increase the compression rate slightly. Thermal compensation consists in injecting a suitable proportion of cold water according to the engine operating mode, inside the chamber at the engine step, after transition from the top dead centre (TDC), as soon as the engine has reached its operating temperature. The water molecules are separated into sudden steam, with the possibility of partial ignition of the hydrogen, a sudden increase in pressure, improvement in combustion, reductions in consumption, CO, CO2. Slight exhaust gas cooling and improved engine output. The invention is explained in more detail using figures. Figure I represents a vaporisation method of water captured on the exhaust manifold, mixed with fuel. Figure 2 represents a vaporisation system with the supply of additional fuel.

Title: Digital signals and frequency correction in a digital wireless system
Inventor: CRICHLOW DAVID N
IPC: H04B1/38
Filed: 1986-11-28
Abstract: A digital wireless subscriber telephone unit for wireless connection with a base station. The subscriber unit has a baseband processor which is coupled to storage device for the baseband functions. The baseband processor is direct access coupled to a modem processor whereby the two processors may communicate with each other. The modem processor generally acts as the master in the system, although lock-out circuit may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified. The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal. On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode. In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with a looped-back signal to produce correction constants to compensate for undesirable variations in the IF, these constants being stored for use in correcting actual received signals. During demodulation, the modulated digital signals are fed to the modem processor in the form of time multiplexed I and Q samples and are demultiplexed. The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.

Title: Fully dry, central tube-type air blown micro optical fiber
Inventor: RUAN YUNFANG
IPC: G02B6/44
Filed: 2013-04-25
Granted: 2015-01-22
Abstract: The present invention is related to an all-dry central tube air blown micro optical cable. The cable consists of an outer sheath and a loose tube which is covered in the outer sheath and inside which the fibers are set, and is characterized in that the water-blocking yarns are coated inside the loose tube and the longitudinal grooves are provided in the outer surface of the outer sheath circumferentially. Compared with conventional cables, the cable according to present invention has a smaller diameter and the less weight, and can be installed in the plastic tubes of 5/3.5 mm or even less at a longer distances. The longitudinal grooves in the outer surface of the outer sheath are not only helpful for the stripping of the optical cable, but also reduce the friction between the optical cable and the wall of the tube in the process of air blown, thereby facilitate the air flow. Furthermore, the use of the sheath material with lower coefficient of friction reduces the drag force of air blown, thus further increases the laying distances of the optical cable. The use of the water-blocking yarns avoids cleaning in the process of fiber splicing, thus greatly reduces splicing time and improves the efficiency of constructions. The cable according to present invention occupies less duct resources and lowers the cost of constructions.
