Granted: 1992-07-14
Abstract: ABSTRACT       FLUOROGENIC AND CHROMOGENIC THREE-DIMENSIONAL IONOPHORES AS SELECTIVE REAGENTS FOR DETECTING      IONS IN BIOLOGICAL FLUIDS        Novel fluorogenic and chromogenic three-dimensional ionophores are provided which selectively bond ions such as potassium, sodium, and lithium, even in neutral aqueous or alcohol media.  The novel ionophores comprise an "ion-recognizing system" fused to a "signal-moiety" through one or more heteroatoms having a non-bonded electron pair.  The signal-moieties are selected from the group consisting of fused ring heterocyclics, fused aromatics, and subsituted aromatics having at least one nitro or azo moiety.  The ion-recognizing system is a three-dimensional cryptand.  The ionophores are ideal for the selective and direct termination of ions in biological or environmental samples and the like.

Abstract: SOLID CAVITY CORNER FOR LOCKSTRIP GASKETS            ABSTRACT OF THE DISCLOSURE       A gasket having an intergral formed corner is disclosed. The corner includes a resilient member having a first and second portion. The first and second portions have free depending ends which are secured to gasket strips to form a peripheral gasket.  The other end of the first and second portions are joined together such that the portions are angled with respect to one another.  Also, the first and second portions each have a first face and a pair of glass securing wings which project from each of the first and second portions.  A channel to receive glass is formed between each pair of the wings.  A first and second cavity to receive locking strips are formed in the first face of the first and second portion, respectively.  A plug is formed at the junction of the first and second portions such that the plug separates the first cavity from the second cavity to enable locking strips to abut against the plug.          The plus exerts force to enhance the seal of the glass in the channel.

Title: Coating composition based on polyepoxides and urethane-containing polyacid curing agents
Inventor: CHANG WEN-HSUAN
IPC: C08G59/40
Filed: 1988-11-09
Granted: 1998-12-01
Abstract: A coating composition suitable for use as an automotive topcoat, particularly a clear coat in a composite color-plus-clear coating, is disclosed.  The resinous binder of the coating composition comprises a polyepoxide and a urethane-containing polyacid curing agent having more than three carboxylic acid groups per molecule and an acid equivalent weight less than 500.  The polyacid curing agent is formed from reacting a polyol component having at least three hydroxyl groups per molecule, a polyisocyanate and an anhydride of a polycarboxylic acid.  The polyacid curing agents have relatively high acid functionality, low acid equivalent weights and good reactivity making them very effective curing agents for high solids coating compositions.

Title: True ttl to true ecl bi-directional tri-statable translator driver circuit
Inventor: KHAN AURANGZEB K
IPC: H03K19/0175
Filed: 1988-11-18
Granted: 1992-06-30
Abstract: Abstract The present invention provides an integrated circuit that has both driver and receiver functions. The circuit of the present invention has two interrelated parts. The first part of the circuit converts true TTL signals to true ECL signals. The second part of the circuit accepts true ECL signals and drives a tri-state true TTL bus. The novel design of the present invention provides a common circuit that acts as an input reference for the circuit that converts true TTL signals to true ECL signals and as a tri-state clamp for the circuit that accepts true ECL signals and drives a tri state true TTL bus.  Using the same circuit components to perform functions in two separate circuits reduces the component count of the resulting circuit and increases the circuit's power/device count figure of merit.

Abstract: ABSTRACT       An image determining apparatus for determining a dot matrix image or a character/line picture on the basis of a halftone image signal obtained by scanning an original image including a dot matrix image or a character/line picture. In order to perform such image determination, first, a pixel block corresponding to a two-dimensional region of a predetermined area is extracted from the halftons image signal, the average pixel density of the extracted pixel block are binarized using the calculated average pixel density as a density threshold. The binarized pixel block is accessed sequentilly in the main scan and subscan directions to check the length and frequency of occurrence of runs of a particular color pixel. If the length and frequency of occurrence of these runs are in a predetermined relationship, it is determined that the pixel block concerned is a dot matrix image or a character/line picture.

Abstract: A duplicate recording system uses video cassettes for storing master library recordings.  On both the recording and the duplicating ends of the system, all signals are buffer stored in an electronic memory while the signals are in a digital form.          This buffer storage completely isolates the recording/reproducing steps so that the usual parameter of restraints disappear.  For example, the duplication ratio may be any value within the capabilities of the recording/reproducing machines.  This isolation eliminates expensive setup procedures heretofore required to switch from one to another duplicating ratio.  The buffer storage also provides a more precise transfer with greater fidelity of the recorded signals.  A computer calculates a smoother analog curve when the digital-to-analog conversion is made.
