Abstract: In the course of the assembly of a circuit-breaker pole, the individual parts of a housing are stacked loosely one on top of the other and fixedly positioned. This fixing can be accomplished by applying subatmospheric pressure or a partial vacuum within the housing and/or by means of a holding device.    Spaces open in the upward direction and located between a fitting and a support insulator as well as between a fitting and a quenching-chamber insulator are then filled with casting material. After this casting material has at least partially hardened, the circuit-breaker pole is turned upside down by rotating the holding device about a horizontal axis, whereupon spaces now open in the upward direction and located between a fitting and the quenching-chamber insulator as well as between a fitting and the support insulator are filled with casting material. This renders possible simple assembly, self-acting mutual alignment of contact pieces as well as a leak test prior to final assembly of the circuit-breaker pole.

Filed: 1993-01-29
Granted: 1998-05-19
Abstract: On receiving a symbol sequence carried by a first-polarization and a second-polarization signal of two orthogonally polarized signals and in order to cancel a cross polarization interference (XPI) component which leaks from the second-polarization signal into the first-polarization signal, a first decision feedback XPI canceller (43) is supplied with a before processed signal derived from the second-polarization signal and with a decided signal which is produced by a decision circuit (22) and which represents the symbol sequence carried by the second-polarization signal with an intersymbol interference component and another XPI component cancelled from the before processed signal.  Another decision feedback XPI canceller (44) is similarly operable.  Preferably, a first decision feedback equalizer (41) is supplied with another before processed signal derived from the first-polarization signal and with another decided signal which is produced by another decision circuit (21) and which represents the symbol sequence carried by the first-polarized signal with another intersymbol interference component and the first-mentioned XPI component cancelled from the last-mentioned before processed signal.  A second decision feedback equalizer (42) is similarly used.          Alternatively, a delay element is used instead of each decision feedback equalizer if the intersymbol interference components are negligible.

Filed: 1993-05-04
Granted: 1997-04-29
Abstract: A system for handling cylindrical cans or the like and conveying them from filler and closure equipment to and into hydrostatic sterilizer carriers.  After the cans have been filled and closed, they are conveyed upright to a receiving area.A screw assembly is periodically actuated, taking cans from the receiving area, grasping their cylindrical sidewalls and laying them down and forward into a metered can stick.  This can stick is rolled laterally by a clamp-kicker assembly into the hydrostatic sterilizer carriers as they are conveyed past it.  The screw assembly includes a pair of horizontally disposed screws, both rotatable downwar-dly and inwardly and with the axis of one spaced above that of the other.  With one complete rotation of the screws a can held therebetween on its cylindrical sidewalls is positively laid forward onto its side.  With an adequate supply of cans in the receiving area, the controlled rotation of the screws determines how manycans are laid forward to thereby form the can stick.  Also, if a sensor detects that a can being conveyed to the screws has fallen down then the rotation of the screws is automatically stopped.

Abstract: The raw lead to be refined, whether of mineral origin or from reclaiming operations, the particle size of which has been reduced to a range not larger than 50 mm, is leached in a suitable apparatus with a solution of ferric fluoroborate in fluoroboric acid.      During the leaching step, lead gets dissolved, with ferric fluoroborate being reduced to ferrous fluoroborate according to the following reaction: 2 Fe (BF4)3 + Pb ~ Pb(BF4)2 + 2Fe(BF4) (1) The leaching apparatus behaves hence as an external anode installed outside of the cell.      The resulting solution is sent to the cathodic compartment of a diaphragm cell in which lead is deposited on a cathode of stainless steel, in compact, highly pure form, from which it is periodically won.      The so depleted-of-lead solution is sent to the anodic compartment of the same cell, in which a suitable anode oxidizes ferrous fluoroborate to ferric fluoroborate.

Abstract: Abstract of the Disclosure:           In an echo cancelling device comprising an echo canceller 13 for producing, in response to a send-in signal SIN and a receive-in signal RIN, a residual signal RES in which an echo signal ECHO is cancelled, a residual echo level estimator 106 estimates, in response to the residual signal, a residual echo level in the residual signal and produces a threshold signal THR with a threshold level equal to the residual echo level. Responsive to the receive-in, the residual, and the threshold signals, a residual echo suppressor 105 produces a send-out signal SOUT with a residual echo adaptively suppressed in response to the threshold level. Preferably, the echo canceller comprises an echo estimating circuit 131 which estimates an echo estimation signal in response to the receive-in and the residual signals.  A subtracter 132 subtracts the echo estimation signal from the send-in signal and produces the residual signal.  Responsive to the send-in and the receive-in signals, a communication state detector 14 produces an inhibit signal INH when a level of the receive-in signal is greater than that of the send-in signal.  The inhibit signal prevents the echo estimating circuit from producing the echo estimation signal and makes the residual echo level estimator keep the threshold level at the residual echo level estimated immediately before the inhibit signal is produced.

Title: Arrangement for measuring the level of contents in a container
Inventor: OTTO JOHANNGEORG
IPC: G01F23/284
Filed: 1995-02-17
Granted: 1999-10-19
Abstract: A continuous measurement of the level of contents in a container is effected by a level measuring device functionong in accordance with the transit time principle by means of waves transmitted from a position located above the highest possible contents level onto the surface of the material in the container. A measuring circuit determines the contents level from the transit time of the useful echo reflected from the material surface. In addition, one or more limit sensors are located at the container, each of which furnishes a signal indicating whether the contents level is above or below a level to be monitored by the limit sensor and which is situated between the minimum and maximum contents levels of the container. The measuring circuit receives the output signals of all limit sensors and uses these output signals to check and eventually to correct the contents level measured value determined by the level measuring device. In particular, the measuring result furnished by the level measuring device can be compared with an exact contents level value every time the contents level reaches the level monitored by a limit sensor whereby the level indication of the limit sensor changes its status. In certain cases, a single limit sensor is sufficient for this purpose, which monitors a contents level which is regularly exceeded or undershot in the normal use of the container.

Abstract: A variable displacement axial piston pump has a plurality of piston bores each connected to an inwardly angled fill port. The fill ports extend from the piston bores inwardly to the working face of the barrel to reduce the diameter of the fill circle of a pump. This decreases the velocity that must be attained by incoming fluid to thereby increase the operating speed at which the pump may be driven where the pump is filled at atmospheric pressure. A pair of staged bleed ports are inserted in the port plate between the fluid inlet port and the fluid outlet port to provide a staged transition for the fluid in the fill ports as these ports move from fluid communication with the fluid inlet port to fluid communication with the fluid outlet port.  Additionally, ports are formed in the surface of the port plate one of which is connected to the pressure port and the other of which is connected to case to dissipate energy within the fill port prior to the time the fill port encounters the suction port of the port plate.
