Title: Educational system for teaching counting and equation solving strategies
Inventor: POCIUS FRANK
IPC: G09B19/02
Filed: 1990-05-24
Granted: 1996-05-07
Abstract: This invention encompasses teaching kits for mathematics and a set of cooperating cards for use with the kits.   A single surface displaying manipulable elements arranged on the surface is used to teach concepts of counting denominate units and evaluating expressions.   Two surfaces displaying manipulable elements arranged on each surface simulate a linear equation.          Four surfaces displaying manipulable elements arranged on each surface simulate a system of two linear equations.  The elements are distinguishable by physical features in such a way that typically as many as three distinct denominate units are displayed with both positive and negative representations.   The invention can be extended,  in general,  to a system of n equations,  with 2n surfaces.   Certain elements mask the occurrence of other elements in such a way as to simulate a variable in an equation.  The cards serve to provide information for utilizing  the boards and also can be employed by themselves.   By manipulating elements a student is taught, in a very concrete and tangible fashion, the strategies necessary to count an array,  solve a linear equation, or solve a system of two or more linear equations.

Title: Removal of the folding carrier and sidebands from an unfolded video signal
Inventor: STROLLE CHRISTOPHER H
IPC: H04N9/79
Filed: 1991-02-12
Granted: 1995-12-05
Abstract: Apparatus is disclosed for processing video information which is reproduced from a magnetic recording medium in a video cassette recorder. The luminance portion of the video signal, which is "folded" about a sampling frequency carrier before recording on magnetic tape, is unfolded after being read from the magnetic tape to restore the bandwidth of the signal, and is applied in parallel through horizontal and vertical comb filters. The combined output of the horizontal comb filter and the vertical comb filter may include incompletely cancelled horizontal and vertical components of the folding frequency and sidebands due to the effects of picture contents. Edge detector means receptive to the unfolded video signal responds to an encountered brightness edge, and generates a signal which varies the proportions of the video outputs of the horizontal and vertical comb filters in the combined output.

Title: Polymerization of vinyl chloride
Inventor: MASUKO SEIICHI
IPC: C08F14/06
Filed: 1990-12-28
Granted: 1996-10-29
Abstract: An improved process for the homo- and copolymerization of vinyl chloride, wherein the inner wall of a polymeriser and those parts of the apparatus which come into contact with the monomer during polymerization are coated with a special coating agent. This agent comprises an aqueous solution of a modified condensate of phenol with aldehyde and has a specified pH value such that it dissolves at a coating temperature and precipitates said condensate when heated on the inner wall of the polymerizer or the like. Since this agent forms a uniform and tough thin film on the inner wall of the polymerizer and the like, it has an excel-lent effect of inhibiting adhesion of a polymer.

Title: Continuous anion exchange chromatography for the separation of zirconium isotopes
Inventor: SNYDER THOMAS STEPHEN
IPC: B01D59/30
Filed: 1991-10-09
Granted: 2002-04-23
Abstract: The thermal neutron capture cross-section of zirconium may be altered by altering its natural isotope distribution through a steady state chromatographic separation of these isotopes using an anion exchange resin as the stationary phase of the chromatographic column. Zirconium is dissolved in a very strong acid which causes the formation of a zirconium anion, such as the ZrOCl4 -2 anion formed in six normal hydrochloric acid, and eluted off the column with a weaker acid. Distinct elution volumes representative of each isotope are collected. In a preferred embodiment, the process also separates the zirconium from hafnium and the other impurities normally present in the product obtained by chlorinating zircon sand and utilizes a continuous annular chromatograph.

Title: Plug-in transient voltage suppressor module
Inventor: BRADY PETER J
IPC: H02H9/04
Filed: 1990-06-11
Granted: 1998-03-24
Abstract: A plug-in surge suppressor module (14A) for insertion into a circuit breaker panel includes four stacks of metal oxide varistors (16, 17, 18, 19) arranged in a cloverleaf pattern on opposite sides of an elongated copper ground bus attached to one lead of each of the metal oxide varistors. The other leads of two of the stacks of metal oxide varistors are attached to a terminal of a V-shaped first resistive wire fuse (24A), another terminal of which is connected to a first AC power line conductor. The other leads of the other two stacks of MOV's are attached to a terminal of a second U-shaped resistive wire fuse (24B), another terminal of which is connected to a second AC power line conductor. A monitor circuit senses the presence of power and continuity of both fuses by pulsing a light emitting indicator diode (46) every cycle of the AC line. A low frequency oscillator circuit produces slow blinking of the light emitting indicator diode which alerts an observer to replace the surge suppressor module if one of the fuses fails.
