Title: Nuclear waste separator
Inventor: OHKAWA TIHIRO
IPC: G21F9/06
Filed: 1999-03-16
Granted: 2002-10-01
Abstract: A method and system for separating radioactive waste containing volatiles, into light ions and heavy ions, includes a loader/transporter for transferring the waste into a high vacuum environment in the chamber of a plasma processor. During this transfer, gases of the volatiles are released from the waste, collected in a holding tank, and subsequently ionized in the chamber. As the volatiles are ionized, the ions are directed by a magnetic field into contact with the waste to vaporize the waste. The waste vapors are then ionized in the plasma processor chamber to create a multi-species plasma which includes electrons, light ions and heavy ions. Within the chamber, the density of the multi-species plasma is established to be above its collision density in order to establish a substantially uniform velocity for all ions in the plasma. A nozzle accelerates the multi-species plasma to generate a fluid stream which is directed from the chamber toward an inertial separator. A magnetic field in the inertial separator effectively blocks electrons in the stream from entering the separator. On the other hand, the inertia of the various ions in the stream carry them into the separator where they are segregated into light ions and heavy ions according to their atomic weights. After segregation, the heavy ions are vitrified for subsequent disposal.

Abstract: A binary signal is encoded to produce a three-level encoded signal having reduced bandwidth and small low frequency and d.c. components, e.g. using modified duobinary encoding, the encoded signal directly modulating a semiconductor laser to produce a frequency modulated optical signal, which is passed through an interference filter to provide two-state amplitude modulation from the three-state frequency modulation for direct recovery of the binary signal by an optical receiver, the interference filter providing constructive and destructive interference for frequencies corresponding to binary one and zero bits respectively. An array transmission system can be provided by combining multiple such frequency modulated optical signals, from multiple lasers with respective central frequencies and respective encoders for multiple binary signals, using an array waveguide which also serves as a channel frequency filter, with a single interference filter. Polarization modulation instead of frequency modulation, and external modulation of an optical signal from an optical source, are also described.

Abstract: The invention concerns a radial-piston hydraulic motor (10), which comprises one or several cylinder groups (1) placed in a stationary position, which cylinder groups contain piston mechanisms (16a1, 16a2,; 17a1, 17a2...) moving radially back and forth. The piston mechanisms (l6a1, 16a2; 17a1, 17a2...) comprise a piston (16a1, 16a2) and a press wheel (17a1, 17a2...). A hydraulic fluid is passed into the cylinder spaces (p1, p2...) of the piston mechanisms so that the press wheels (17a1, 17a2...) of the pistons (16a1, 16a2...) that are at a power stage are pressed with force against the wave-shaped face (12a) of the cam ring (12) and bring the cam ring (12) into a revolving movement. The cam ring (12) is connected with a box frame (11) and the box frame (11) with a distributor valve (13), which controls the pressurized fluid flow at the correct time into the cylinder spaces (p1, p2...) of the pistons (16a,, 16a2...) that are at the power stage, and that, at the same time, the distributor valve (13) connects the cylinder spaces (p1, p2) of the pistons (16a1, 16a2...) that start their return movement to a lower pressure. In the equipment, the sense of rotation of the motor can be reversed by reversing the direction of flow of the fluid through the distributor valve (13). The fluid is passed to the distributor valve (13) through the sets of ducts (e1, e2) in the shaft (14) which is placed in a stationary position together with the cylinder frame(s) (15) of one or several cylinder groups (1). In the distributor (13) in accordance with the invention, there is a duct (31), which communicates with the power pressure and which is opened on the side face (13a) of the distributor (13). In this connection the force is applied, through the fluid at the power pressure, to the side face (13a) of the distributor (13).

Title: Line card loss of battery detector
Inventor: SCIABICA FRANK
IPC: H02J7/00
Filed: 2001-03-12
Granted: 2006-01-10
Abstract: A line card circuit to prevent false off-hook signals resulting from the permanent loss of battery voltage at a line card. In the battery present condition, the 5V operating voltage is connected to the collector lead of an NPN transistor, which also supplies the output signal of the system. The emitter lead of the transistor is connected to ground. The -48V battery voltage is connected to the transistor base lead and biases the base negative with respect to the emitter, maintaining the 5V logic "1" output signal on the collector lead. There is a resistor and capacitor in series, forming an RC circuit, across the 5V collector lead and the -48V base lead. In the battery present condition, there is a significant charge across the capacitor. In the battery absent condition, the -48V battery voltage is lost and the voltage on the base lead rises to a positive voltage in a time interval governed by the discharge time of the RC circuit, thus causing the system output signal to drop to logic "0".
