Patent CA-2096169-A1 (CA)
Title: Negative feedback sense pre-amplifier
Inventor: BRUNOLLI MICHAEL J
IPC: G11C7/06
Filed: 1993-05-13
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: Lead-acid battery electrode and method of manufacture
Inventor: WITHERSPOON ROMEO R
IPC: H01M4/20
Filed: 1993-06-17
Abstract: LEAD-ACID BATTERY ELECTRODE  AND METHOD OF MANUFACTURE          Abstract of the Disclosure Positive plates are prepared by forming partially oxidized tetrabasic lead sulfate (4 PbOn - PbSO4) having at least a part of the oxide (PbOn) portion in the form of alpha lead dioxide (.alpha. - PbO2), and forming beta lead dioxide (B-PbO2). Next the oxidized tetrabasic lead sulfate (OXYTTB) and the beta lead dioxide are intermingled in a wet mixture.  The wet mixture is applied to the oxidized surface of a lead support substrate. Then, it is heated and pressed for a time and at a temperature and compressive load sufficient to form an adhered or retained coating of active material on the substrate. The OXYTTB is formed by reaction of tetrabasic lead sulfate with magnesium hydroxide and sodium persulfate. Preferably, beta leadd dioxide is formed by reacting red lead oxide (Pb3O4) with nitric acid to provide an oxidation product, at least a major portion of which is beta PbO2, and which has a surface area of at least 10 m2/gram.
Patent CA-2100810-A1 (CA)
Inventor: HANNING DAVID M
IPC: F24H1/18
Filed: 1993-07-19
Abstract: The storage tank portion of a water heater has an outwardly projecting threaded pipe coupling fitting and is disposed within a jacket structure that forms an enclosed insulation space around the storage tank, the outer end of the pipe coupling fitting being spaced inwardly apart from a pipe connection opening in the jacket structure.  A generally tubular foam stop  member having a convexly curved side portion is positioned within the insulation space before the space is filled by an injection process with a liquid foam insulation material. The foam stop member  receives the pipe coupling,  is axially pressed between the storage tank and the jacket structure, and forms a seal around the pipe coupling fitting and around the jacket structure pipe connection opening.  During injection of the liquid foam insulation material into the enclosed insulation space, the foam stop member  serves as a relatively small barrier that essentially precludes the liquid foam from escaping outwardly through the jacket structure pipe connection opening or entering the pipe coupling.

Inventor: MONTHONY JAMES F
IPC: C12M1/24
Filed: 1993-09-03
Abstract: This invention describes a method for the rapid identification of the presence of microorganisms in a sample.      Briefly, in the method of this invention the sample container is divided into a plurality of discrete zones, each of which can be separately monitored for microbial presence. When a sample is placed into this container, detection is simplified as the volume monitored is low (as compared with the sample); since microbial detection is a concentration dependent phenomenon, the speed with which the presence of microbial contamination can be detected is increased.

Inventor: GOLD PHILLIP J
IPC: G05D1/06
Filed: 1992-07-31
Abstract: A vertical control system for a rotary winged aircraft receives inputs from a displacement collective stick and a sidearm controller. The system provides a set point for the vertical rate of change of the helicopter as a function of a vertical lift command signal from the sidearm controller. The set point is used as a reference for an altitude rate of change feedback path, and an integrated value of the set point is used for an altitude feedback path. The set point is also input to a feedforward control path having an inverse vehicle model to provide a command signal indicative of the command for aircraft collective pitch necessary to achieve the desired set point. Signals from all three paths (i.e., the altitude rate of change feedback path, the altitude feedback path, and the feedforward path, are summed to provide a signal to backdrive the displacement collective which controls main rotor collective pitch.
