Title: Cable coupling transformer
Inventor: WATSON MICHAEL BARRY
IPC: H01F19/06
Filed: 1991-03-27
Granted: 2002-02-12
Abstract: A cable coupling transformer comprises a metal or ferrite former defining separate high permeability portions of a pair of flux paths, a winding electromagnetically associated with each high permeability portion, and a common low permeability por-tion of each flux path which passes between a pair of conductors carrying equal currents in antiphase. A portion of the current induced in either the conductors or the windings are impressed on the other to create a simple communications device.
Patent CA-2080070-C (CA)

Granted: 2002-05-07
Abstract: Ce dispositif comprend un émetteur d'ultrasons (4) dont l'extrémité inférieure (6) est immergée dans la solution réactive (2) dans laquelle est plongée une tôle (3) à décaper, et cette extrémité est équipée de deux pavillons (6, 7) positionnés de part et d'autre d'une rive de la tôle (3) avec leurs surfaces émettrices pla- nes parallèles à la tôle et situées dans deux plans antinodaux; de ce fait les deux pavillons (6, 7) vibrent en opposition de phase, et si l'amplitude vibratoire est suffisamment élevée, ces vibrations créent une cavita- tion dans le liquide, dans l'espace intercalaire entre les surfaces (3a, 3b) de la rive et les pavillons (6, 7), ce qui accélère considérablement la vitesse de déca- laminage de la rive.

Title: Negative feedback sense pre-amplifier
Inventor: BRUNOLLI MICHAEL J
IPC: G11C11/419
Filed: 1993-05-13
Granted: 1998-10-27
Abstract: A static RAM cell having first and second differentially connected lines reads binary information stored in the cell by providing a current through the cell and the first line to read a binary "1" or through the cell and the second line to read a binary "0".  First and second transistors in a pre-amplifier respectively connected in the first and second lines provide outputs respectively representing a binary "1"   and a binary "0".  The first and second transistors pass control currents respectively through third and fourth transistors to produce bias currents in one of the first and second transistors when reading currents are not passing through that transistor and the cell.  The control of the third and fourth transistors increases the frequency at which information is read from the cell and is amplified.  In this improvement, the bias current in the line providing an output at each instant is reduced by respectively providing a negative feedback from the outputs (e.g. the drains) of the first and second transistors to control the inputs (e.g. the gates) of the third and fourth transistors. This reduces power losses while increasing the frequency at which binary information is read from the cell.  The frequency may be further increased by including an impedance in the control circuitry to the third and fourth transistors to delay the response of the third and fourth transistors.  Pairs of pre-amplifiers for different bit and word lines may be connected in parallel to provide further increases in the frequency response and further power losses.

Title: Drop detection method and apparatus
Inventor: YERLIKAYA DENIS Y
IPC: A61M5/168
Filed: 1992-03-31
Granted: 2003-05-20
Abstract: A drop detector system and method are provided for a drop detector of the type including a drop chamber (30) and an electro-optical sensor (40).   The detector system detects drops passing through an optical sensing path between a detector (40) and at least one light source (38). In response to the detection of a drop passing through the optical path, the detector produces an output signal. A capacitator is connected between the detector and an amplifier to block the DC component of the output signal. After amplifica-tion, the signal is passed through a low pass filter to further block signals caused by undesirable factors. The cutoff frequency of the low pass filter is controlled by a microprocessor that controls the pump that pumps liquid from the drop chamber. The detector and light source or sources are ar-ranged to detect drops falling in the drop chamber at virtually any angle and is virtually any ambient light condition.

Filed: 1995-01-25
Granted: 1999-11-30
Abstract: The socket has a housing, an outer sleeve on the housing centered on an axis and having an axially extending and radially inwardly open groove. A latching element in the housing in axial alignment with the groove is displaceable axially relative to the outer sleeve. A spring or other biasing unit is braced between the element and the housing for urging the element into an outer position and a mechanical coupling between the latching element and the switch prevents a switch on the housing the switch from moving from its the position to its on position except when the element is in an inner position. A nonmatching plug has a body formed with a radially outwardly open recess and respective contacts in the body are engageable with contacts of the outer sleeve. A tubular adapter body is fittable over the plug body and inside the outer sleeve in an inserted position with the plug contacts engaging the socket contacts.      A radially outwardly projecting bump on the tubular body engages the latch element to hold same in the inner position in the inserted position, and a retaining element on the outer sleeve projects radially inward into the recess of the plug body and bears radially outward against the outer sleeve only in the inserted position so that in the inserted position the bump holds the element in the inner position and the retaining element locks the adapter and plug in the outer sleeve.

Title: Fluid bed desulfurization
Inventor: CAMPBELL WILLIAM MARTIN
IPC: B01J20/34
Filed: 1995-04-12
Granted: 2005-11-15
Abstract: A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is than separated from a desulfurized effluent gas and regenerated by contact with an oxygen-containing gas in a transport riser. The regenerated sorbent is separated from an SO2 containing offgas and recycled to the desulfurization step. The degree of sorbent conversion in the desulfurization step is held at a low level and the sorbent regeneration rate is increased to avoid excessive temperature rise in the regeneration step. In such manner, sorbent cooling can be substantially eliminated. The regeneration riser preferably comprises a once-through lift riser to minimize the riser transport gas requirements to just oxidant gas or oxidant gas mixed with a reduced amount of diluent gas. A reduction in use of diluent gas give a relatively high offgas SO2 concentration of as much as 15 mole percent, suitable for sulfuric acid manufacture and/ or reduction to sulfur.

Title: Sinker for a circular knitting machine
Inventor: HUNG JUNG HAO
IPC: D04B15/06
Filed: 1995-05-26
Granted: 1998-11-03
Abstract: Disclosed is a sinker for a circular knitting machine being characterized by two symmetrical L-shaped recesses formed at two lateral sides of an upper half of a front top portion of the sinker, including a nose and a nose slot formed above the portion.  The L-shaped recesses are so formed that, when the sinker is moved into a corresponding channel on the needle cylinder in front of the sinker, the recesses are located slightly above the channel.  When the sinker reciprocates back and forth to together with the up and down latch needle form and knit piles, dust so produced settles on the L-shaped recesses and is removed therefrom without falling into and cumulating in the channel of the needle cylinder due to the movements of the sinker at high speed.  The cleaning of needle cylinder and sinkers can be minimized and the quality of knitted fabrics can be enhanced with the arrangement of such L-shaped recesses on two sides of the sinker.
