Title: Shrinkage-resistant ultraviolet-curing coatings
Inventor: GASKE JOSEPH E
IPC: C08F299/02
Filed: 1987-03-18
Granted: 1991-09-24
Abstract: SHRINKAGE-RESISTANT              ULTRAVIOLET-CURING COATINGS                       ABSTRACT        An ultraviolet-curable liquid coating composition which possesses minimal substrate deformational shrinkage on cure is disclosed in which (A) a cationically curable polyepoxlde having a 1,2-epoxy equivalency of at least 1.3 is used in admixture with (B) an acrylate-functional compound which is either (1) a monoacrylate-functional compound carrying at least two primary hydroxy groups; or (2) an epoxy-functional monoacrylate in admixture with a compound carrying a plurality of primary hydroxyl groups.  An acrylate-functional liquid (C), preferably a monoacrylate, is used to provide coating viscosity, and a catalyst component capable of initiating, on ultraviolet exposure, both the conventional free-radical polymerization of ethylenically unsaturated monomers, and the cationic polymerization of polyepoxides in the presence of a compound carrying the primary hydroxy group.  This catalyst component usually comprises a radiation sensitive aromatic onium salt capable of releasing a Lewis acid when exposed to radiant energy, together with an effective amount of a ketonic free radical photoinitiator when the onium salt is ineffective to perform this function.  This provides a two stage cure in which shrinkage is minimized to control curling and cupping of easily deformable coated substrates.

Abstract: ABSTRACT OF THE DISCLOSURE            A sequence controller of an instruction processing unit (IPU) in a data processing system places the IPU is either a ready, go, hold-on-old, hold-on-new, or cancel state.  If the IPU is ready to execute another instruction, the sequence controller places the IPU in the ready state.  When an instruction is received for execution, and execution commences, the sequence controller places the IPU in the GO state.          If at least one or more operands associated with the execution of an instruction are not ready when execution is scheduled to commence, the sequence controller places the IPU in a hold-on-new state, holding the pendency of the execution of the particular instruction, until the operands are available.  If one or more other functional units in the data processing system are not ready (busy) during execution of the instruction, and the other functional units are needed to complete execution of the instruction, the sequence controller places the IPU in a hold on old state, holding the execution results thus far generated, until the functional units become available.  If the functional unit remains busy, or if an error in the functional unit is confirmed, the sequence controller places the IPU in the cancel state.  If the functional unit recovers from the error, and/or the functional unit is no longer busy, the sequence controller causes the IPU to leave the hold-on-old state, and the execution of the instruction is completed.  When the one operand becomes available, the sequence controller causes the IPU to leave the hold-on-new state, and the execution of the instruction is completed.

Abstract: ABSTRACT OF THE DISCLOSURE           A vertical beam spectrophotometer for measur-ing the light absorption of an assay prepared using standard wet chemistry procedures and conventional solid phase coated bead technology is disclosed.  The spectrophotometer measures the absorption of the assay in a conventional reaction cuvette with the bead remain-ing in the cuvette.  The light source of the spectro-photometer illuminates the bead, which diffuses the light into the surrounding assay solution.  A lense projects the diffused light onto a photocell which con-verts it into an electrical signal having magnitude related to the light absorption of the assay.  The signal is processed in a known manner by conventional processing circuitry to obtain an absorption value.

Abstract: Abstract Optical Communication System, Particularly in the Subscriber Area An optical communication system in which transmission takes place in a single optical-waveguide mode by means of low-cost optical transmitters and receivers although two or more modes could propagate in the optical wave-guide (1) at the operating wavelength, is supplemented by optical-waveguide sections (2, 3) between the trans-mitters (S, S1, S2) and receivers (E, E1, E2) and the optical waveguide (1) which are "single-mode" at the operating wavelength and contain the optical connectors (4, 5). This eliminates the need for connectors at the junctions between the optical-waveguide sections (2, 3) and the optical waveguide (1), so that no modal noise and modal dispersion can occur as a result of mode conversion.

Abstract: ABSTRACT      The present invention is a process for applying a highly permeable coating on a hollow fiber substrate.  The hollow fiber substrate is continuously passed through a polymeric coating solution and withdrawn from the solution through a coating die to form a uniform polymeric solution coating on the outer surface of the hollow fiber.  A portion of the solvent from the coating is allowed to evaporate thereby forming a thin, dense surface layer after which the remaining solvent from the coating layer is leached out.  The resultant material is a highly permeable, coated composite hollow fiber membrane which can be used in gas and/or liquid separations.

Abstract: ABSTRACT OF THE DISCLOSURE Circuitry for producing an extremely linear frequency modulated audio carrier for use in the headend of a video signal distribution system, such as a cable television system. A reference oscillator operating at a relatively high frequency, such as the video carrier frequency, generates a signal which is divided down to a relatively low frequency. A voltage controlled oscillator operating at the relatively low frequency is used to frequency modulate the audio signal. After modulation, the audio carrier is upconverted utilizing a signal frequency which is also derived from the original reference frequency, thus providing a stable and linear frequency modulated audio carrier particularly suitable for transmission of stereo program audio.
