Patent CA-2029802-A1 (CA)
Inventor: ROSENKRANZ WERNER
IPC: H04L27/14
Filed: 1990-11-13
Abstract: 1. Receiver with direct quadrature sampling of the input signal. 2.1 In a receiver in which a normal component and a quadrature component of a signal modulated on a carrier signal are directly produced by carrier signal sampling, the analog-to-digital converter is controlled by means of periodically recurrent sampling pulses having a certain frequency. 2.2 In order to create enhanced selection options from the selectable carrier frequencies it is proposed by this invention to combine a plurality of equidistant sampling instants to a group and to select for the distance between the last sampling instant of one group and the first sampling instant of the next group a time interval different from the distance in time between two successive sampling instants within one group. 2.3 Field of application of the invention is, for example, mobile radio receivers.

Abstract: A multilayer non-irradiated film comprising a core layer, a respective further layer laminated to each side of the core layer, and an additive capable of migrating within the film, is prepared by: (i) blending an additive, such as a fungicide, encapsulated in a first thermoplastic resin, with a second thermoplastic resin which has a lower melting point than the first resin so that during extrusion of the blend the second resin melts and surrounds the encapsulated additive before the first resin melts; and (ii) coextruding the resulting blend to provide a layer, preferably the core layer, of the film and respective thermoplastics resins to provide the other layers of the film.      Preferably a five layer film is formed in which a respective intermediate layer is provided between the core layer and each outer layer.

Title: Red fluorescent materials with a non red visual color
Inventor: AUSLANDER JUDITH
IPC: C09D11/00
Filed: 1991-11-13
Abstract: Solution inks have been discovered that have an acceptable red fluorescent signal for machine detection while emitting a different visual color in white light. The formulation is based on a combination of a fluorescent dyes and a non red dye belonging to the spectral sensitizer class of dyes.      The red fluorescent dye and non-red dye are combined in a resin to form a toner. Because of a bathochronic shift, fluorescence at higher wave lengths is achieved. Upon dissolving the toner in a polar solvent, increased viscosity is achieved which results in an enhanced fluorescent signal as compared to prior fluorescent inks.

Title: Process for preparing modified polyphenylene sulfide resins
Inventor: SAKANE TAKEHIKO
IPC: C08G75/02
Filed: 1992-06-12
Abstract: ABSTRACT OF THE DISCLOSURE:      Melt viscosity of polyphenylene sulfide materials highly susceptible to curing reaction is increased at a moderate rate that is convenient for attaining a desirably increased melt viscosity at a precisely estimated time in the course of curing process.  The curing process is carried out by heating the curing-susceptible polyphenylene sulfide material at about 190 - 270°C in a non-oxidizing, inert gas.  The process is monitored by measuring the weight loss percentage of the material upon heating at intervals during the process.  When a weight loss upon heating at 330°C for 30 minutes has dropped to a level of not greater than 0.4 wt.%, the curing process may be completed to give a cured PPS having a use-fully increased melt viscosity.
