Title: A method of controlling the frequency of a coherent radio receiver and apparatus for carrying out the method
Inventor: RAITH ALEX KRISTER
IPC: H04L7/00
Filed: 1990-01-04
Abstract: The invention relates to a method and an arrangement for controlling the frequency of a radio-receiver which receives signal-sequencies which have been subjected to interference and which include a synchronizing-sequence and a data-sequence. A signal-sequence is A/D-converted (3) to signal-points (I,Q) intended for analysis, and a Viterbi-algorithm (10) is adapted (12,13) to the prevailing interferencies with the aid of the synchronizing-sequence. The data-sequence is Viterbi-analyzed through a large number of calculating stages, for the purpose of determining the bit-sequence of the data-sequence. According to the invention, a bit-sequence is extracted during the Viterbi-analysis, with a time-delay (TE), subsequent to effecting a few calculating stages, and a corresponding extracted signal-point is calculated (14). The analysis-intended signal-point corresponding to the extracted signal-point is divided and time-delayed (16,TE), and phase-compared (15) with the extracted signal-point. Corresponding phase-comparisons are made with respect to consecutive signal-points in the data-sequence and the angular magnitudes obtained in the phase-comparison are low-pass filtered and integrated (17) to form an angle-shift signal (V). The analysis-intended signal-points are displaced angularly (11) by the angle-shift signal (V) prior to the Viterbi-analysis.

Title: Graft copolymer pigment dispersants
Inventor: SHEAU-HWA
IPC: C09D7/45
Filed: 2001-06-01
Abstract: A polymer dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of 3,000-100,000 and comprises a polymeric backbone and macromonomer side chains attached to the backbone, wherein   (1) the polymeric backbone is formed of polymerized ethylenically unsaturated monomers and (2) the side chains are macromonomers that are attached to the backbone at a single terminal point and are formed from polymerized ethylenically unsaturated monomers and have a weight average molecular weight of about 1,000-30,000 wherein the graft copolymer contains about 2 to 70% by weight, based on the weight of the graft copolymer, of polymerized ethylenically unsaturated monomers containing acetoacetate groups that are polymerized into the backbone, side chains, or both, and the acetoacetate groups are reacted with a primary amine to form a pendant acetoacetyl amine group on the graft copolymer which serves as the pigment anchoring group. These materials are effective in dispersing and stabilizing a wide range of pigments in solvent based systems and are particularly useful in forming pigment dispersions that are used in a variety of solvent borne coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.

Date May 11, 1994An engine for driving a piston arrangement for pumping water from an inlet to an outlet at a higher level is disclosed. The engine includes a hollow housing having an inlet and an outlet between which liquid passes, the housing at least partly enclosing a chamber through which the liquid flows from the inlet to the outlet. A movable wall is mounted in the housing and partly defines the chamber. A valve is provided to open and close the outlet so that when it closes, liquid in the chamber is suddenly decelerated producing an increase in pressure in the chamber to force the wall to move to a direction so as to increase the volume of the chamber. After an initial increase in the pressure, the water relaxes and the pressure decreases to such an extent that a spring will open the valve and the spring returns the wall to the position of decreased volume in the chamber. Thus, the wall is caused to reciprocate under the influence of pressure of the liquid increasing and decreasing as the valve is opened and shut.
