Title: Polymerisation process for preparation of non-aqueous dispersions of microparticles and coating compositions containing said microparticles.
IPC: C08F2/20
Filed: 1980-12-05
Abstract: A process is described for making sterically stabilized non-aqueous dispersions of composite polymer microparticles, in which (1) monomers including at least one crosslinking monomer are polymerized in an aqueous medium at a temperature at least 10 DEG higher than the glass transition temperature of the polymer to be formed, in the presence of a block or graft copolymer stabilizing agent, under conditions such that there is at no time present a separate monomer phase, (2) further monomers, not including any crosslinking monomer, are polymerized in the dispersion thus obtained, the presence of a separate monomer phase again being avoided, and (3) the microparticles are transferred from the resulting dispersion into a non-aqueous medium which is a solvent for the non-crosslinked polymer generated in (2). The microparticles are of value for incorporation into coating compositions the main film-forming constituent of which is compatible with the non-crosslinked component of the particles.

The information transmitted in digital form has other identifying material and is transmitted generally synchronously with the corresponding information in analog form. The transmissions are received by receivers with detectors sensitive to the identifying material and which have analog-digital and inverse conversion means as well as memory and decoding means to reproduce the information contained in the analog and digital signals.
Patent ES-8302975-A1 (ES)
Title: Adaptive equalizer
IPC: H04L25/03
Filed: 1982-02-10
Abstract: In a digital system, especially where PCM coded speech is conveyed over twisted pair cables optimized for analogue speech, a pulse is received distorted, the distortion being especially bad on the trailing edge of the pulse. This decays slowly enough to cause intersymbol interference with the next pulse. This is overcome by applying the signal from an amplifier (11), FIG. 4, to one input of a subtractor (12) via a delay and attenuation circuit (13-15) and to the other input of the subtractor directly. The delay (13) is such as to optimize the peak of the received pulse, and the attentuation level is calculated to cancel out the tail of the received pulse so that it is zero at the center of the sampling point of the next bit.

IPC: G01S13/26
Filed: 1984-07-11
Abstract: N signals are received, where N is an integer greater than one. N signal channels are employed and in each one the signal is sampled (at 1,2,3,4) by its respective phase of an N phase clock pulse generator, delayed (at 6,7,8,9) and then compared to a reference pattern in a digital correlator (10,11,12,13). The signal is shifted against the fixed reference on every clock pulse and when signal and reference are identical an output is obtained from the correlator. Correlator outputs are summated (14) to provide the time-of-arrival indication I when the correlators produce outputs simultaneously. - A correlator comprises a fixed and a shift register to respectively contain the reference and signal patterns. EXCLUSIVE- OR gates are used, one for each fixed register stage. A summing circuit combines the outputs of the gates. With a clock generator period of say T seconds the time-of-arrival may be determined to an accuracy of + or - 2T/N seconds.

Title: Method of converting webs or sheets of securities into bundles of securities.
IPC: B41F11/02
Filed: 1985-07-02
Abstract: Processing is based on print carriers in the form of security paper webs or security paper sheets, containing security paper prints which are arranged in the manner of matrices in transverse rows and longitudinal rows and on which spoilt notes are identified by a mark which can be read by a reading instrument. The print carriers pass, in succession, by a reading instrument which detects the positions of the spoilt notes and feeds them into a computer for storage, a cancellation printer controlled by this computer, which provides spoilt notes with a cancellation print, and a numbering machine. The numbering mechanisms of this numbering machine are moved forward by the computer in such a way that always the satisfactory security paper prints, placed in succession in any longitudinal row, are serially numbered, the spoilt notes being neglected. Subsequently, the print carries, having passed by another reading instrument, are cut up into individual security papers, the spoilt notes are separated out in a separation device and the remaining, serially numbered individual security papers are assembled to form bundles, each having a complete numerical sequence. In this way, correct and complete numerical sequence of the security papers contained in the automatically produced security paper bundles and security paper parcels is ensured, in spite of the separation of spoilt notes.

Title: Solid-phase hybridization assay using anti-hybrid antibodies.
IPC: C12Q1/68
Filed: 1986-06-20
Abstract: A nucleic acid hybridization method for detecting a particular polynucleotide sequence present in a virus or cell contained in a test sample such as a biological fluid. The test sample is treated to release nucleic acids from the virus or cell of interest in single stranded form and to immobilize such nucleic acids on a solid substrate such as a filter membrane. Release of nucleic acids can be accomplished with alkali, lytic enzymes, detergents, and the like. The immobilized nucleic acids are contacted with a probe to form DNA.RNA or RNA.RNA hybrids which are then detectable by binding of an anti-hybrid antibody reagent, preferably labeled. The method does not require the use of labeled probe and provides quantitative results due to the efficiency and stability of the immobilization of sample nucleic acids.
