Title: Apparatus for digitally controlling the d.c. value of a processed signal
Inventor: CANFIELD BARTH A
IPC: H04N5/45
Filed: 1990-03-29
Abstract: RCA 85,498 Abstract of the Disclosure A digital D.C. control system includes a multiplexer, a digital-to-analog converter, a capacitor, offset generating circuitry and clamping circuitry. A digital signal to be D.C. controlled and a digital brightness control signal are alternatively coupled by the multiplexer to the input of the digital-to-analog converter. The output from the digital-to-analog converter is coupled to a system output terminal via the capacitor. When the signal is applied to the digital-to-analog converter a fixed D.C. offset is applied to the interconnection of the converter and capacitor. During preselected intervals the D.C. control value is coupled to the digital-to-analog converter concurrently with the system output terminal being clamped to a fixed reference and the D.C. offset circuitry being disabled. This combination of apparatus permits controlling the D.C. level of a digitally processed signal without affecting the dynamic range of the digital signal.

Patent CA-2014709-A1 (CA)
Inventor: MONTGOMERY GARY V
IPC: B65D41/04
Filed: 1990-04-17
Abstract: A closure including a standard threaded cap having a tamper indicating band depending from the cap skirt by frangible webs. The tamper indicating band has an inwardly directed bead which cooperates with a flange on the container neck which allows the band to rotate with the cap but prevents the band from being removed past the container flange.  Alternatively the tamper indicating band contains spaced ratchet teeth which engage ratchet teeth on the container neck to prevent further rotation. A rotary seal is provided between the cap and container neck which is effective for an axial length A greater than the sum of a distance B between the cap bead and the container flange when the cap is tightened or the axial movement of the cap in rotating the ratchet teeth into contact and the distance C which the frangible webs stretch before fracture. Thus the rotary seal prevents access to the product prior to breaking the tamper indicating band loose from the cap.

Title: Cell surface antigen that binds with l6 monoclonal antibody
Inventor: NILAVER GAJANAN
IPC: G01N33/577
Filed: 1990-05-01
Abstract: CELL SURFACE ANTIGEN THAT     Abstract of the Disclosure We disclose the discovery and purification of a tumor antigen that binds the mouse monoclonal antibody L6.          Immunohistochemical analysis showed that the antigen is expressed on the membrane surface of LX-1 human lung tumor cells, which retain L6 binding activity when intracerebrally xenografted in nude rats.  The antigen is also expressed in the cytoplasm of hypothalamic neurons.          Inability of oxytocin and vasopressin hormones to block L6 binding showed that the antigenic epitope resides in neurophysin, the carrier protein associated with the two hormones.  Porcine neurophysin did block L6 binding to the antigen.  Western blot analysis confirmed that L6-immunoreactivity is neurophysin-related.          Immunoaffinity chromatography and gel electrophoresis revealed the antigen molecular weight to be 45000 daltons.          Amino-terminal sequencing revealed a 21-amino acid homology with the N-terminus of human pro-pressophysin.

Title: Measurement of cardiac performance
Inventor: PEARLMAN ANDREW L
IPC: A61B5/352
Filed: 1990-09-26
Abstract: Abstract Cardiac performance is measured by measuring the left ventricular  pressure,  measuring  the  left  ventricular volume, determining the product of the left ventricular pressure and the left ventricular volume as a function of time, determining the time derivative of said product; and determining the slope of the time derivative, as it rises thereby to provide an indication of the cardiac power index.  In this invention, the left ventricular pressure is measured by measuring the arrival times of cardiac pressure pulses at a given site at a plurality of pressure values.    Preferably,  the  largest  number  of  pressure measurements is conducted in the interval during the early ejection phase.   This method reliably measures cardiac performance under resting and/or exercise stress conditions to enable measurement of the cardiac power index.

Title: Exhaust gas purification system for an internal combustion engine using alcohol blended gasoline for fuel
Inventor: KATOH KENJI
IPC: B01D53/94
Filed: 1990-11-28
Abstract: ABSTRACT OF THE DISCLOSURE An exhaust gas purification system for an internal combustion engine using an alcohol blended gasoline fuel includes a lean NOx catalyst capable of reducing nitrogen oxides under an oxidizing gas condition and in the presence of hydrocarbons.  A bypass conduit is provided with a bypass valve so as to bypass the lean NOx catalyst.  Opening of the bypass valve to cause the exhaust gas to flow through the bypass conduit is controlled in accordance with the alcohol concentration of the fuel.  When the alcohol concentration is low, the bypass valve opening range is limited to a high engine speed and high engine load range, so that the exhaust gas is caused to flow through the lean NOx catalyst at low and medium engine speeds and low and medium engine loads, and the catalyst is utilized at a maximum.  On the other hand, when the alcohol concentration is high, the bypass valve opening range is determined so as to include a medium to high engine speed and medium to high engine load range, so that the exhaust gas is caused to flow through the bypass conduit at medium engine speeds and medium engine loads, and useless degradation of the lean NOx catalyst is prevented.

Title: Apparatus for forming voids in concrete and method of use thereof
Inventor: CASS RONALD L
IPC: E04B5/16
Filed: 1991-01-03
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus for forming voids in concrete and the method of using the apparatus.   The apparatus includes baseplates secured to a wood supporting deck or form for a concrete floor by a plurality of removable screws in a location determined by the plans of the concrete floor which usually requires the formation of various voids, cavities, openings or holes in the floor and a removable sleeve attached to each baseplate and having a height generally equal to the thickness of the floor with the upper end of the sleeve being accessible and observable when concrete is poured. In using the apparatus, the baseplates are affixed to the wood deck in accordance with the plans for the floor after the wood deck has been placed in position to receive poured concrete.   After the baseplates have been secured in place, various subsequent work procedures may be carried out without the workers encountering obstructions that would exist if upwardly projecting cavity forming members were attached to the wood deck.   Such work procedures include the positioning of reinforcing bars, cables and the like which have a tendency to dislodge and damage any upward projections on the wood deck.   After all work procedures  have  been  performed  on  the  wood  deck, including positioning of rebars, a sleeve is attached to each baseplate immediately prior to pouring concrete thereby eliminating the problem of upwardly projecting cavity forming members on the wood deck being displaced or damaged  during work procedures  prior to  pouring concrete.  After the concrete has been poured and set, the sleeves are detached from the baseplates and removed.          The wood deck can then be stripped from the bottom of the concrete  floor  with  the  baseplates  still  attached thereto.  The baseplates are then removed from the wood deck panels and the baseplates and sleeves are capable of reuse.   In other situations,  The baseplates can be detached from the wood deck before the wood deck is stripped by using a long screwdriver to remove the screws after which the baseplate can be lifted out of the cavity.  If a "flying form" is used, the baseplates can remain attached to the deck.

Abstract: Tomatoes  are  dehydrated  by  selecting  red,  ripe tomatoes and washing the selected tomatoes with a biocide and then rinsing with fresh water.   The rinsed fruit is cut  into  approximately  cubical  chunks  and  blanched by heating  the  chunks  to  a  temperature  at  or  below  the boiling  point of water  for  a  period  of  less  than  10 minutes  to  inactivate  the  enzymes  contained  in  the tomato.   The  blanched  tomatoes  are  cooled  to  room temperature  and  then  pulped.   After  removing  skin  and seeds to form a tomato juice from the pulped chunks, the juice is  evaporated under vacuum to  form a  paste-like concentrate having  a solids  content  from about  20%  to about 35%.  Air trapped in the concentrate is removed.  The concentrate is  then formed into pieces and dried until the moisture content of the pieces is between about 3% and about 4%.
