Title: A method for the preparation of polyvinyl chloride resins
IPC: C08F2/00
Filed: 1979-11-13
Abstract: In the method for the preparation of a vinyl chloride-based resin by aqueous suspension polymerization of vinyl chloride monomer in which the polyvinyl chloride resin product is modified by a modifying resin or other agent having different properties from the resulting polyvinyl chloride resin, the modifying agent or resin is added to the polymerization mixture slurried in an aqueous medium together with a latex of a synthetic polymer at a time when the conversion of the monomer to polymer is in the range from 3 to 85%. It is also essential that the average particle diameter of the modifying agent or resin is in the range from 10 to 200  mu m and that of the polymer particles in the added latex is in the range from 0.01 to 5 mu m in order that good coalescence is obtained between the particles of the modifying agent or resin and the polyvinyl chloride resin.

Patent GB-2056769-A (GB)
Title: Dual wavelength laser annealing of material
IPC: B23K26/00
Filed: 1979-11-15
Abstract: New mode of radiant heating wherein two different wavelength pulses (FIG. 7, 42, 43) are used to melt portions of a solid body (41). The first pulse may be of relatively weak intensity, but is strongly absorbed by the solid. The second pulse, which is not strongly absorbed by the body when in the solid phase, is strongly absorbed by the body when in the molten phase. Exposure to the first pulse results in an initial melting of the body, which then becomes highly absorptive to radiation at the wavelength of the second pulse. Readily available radiant energy sources, e.g., lasers, which generate radiations generally not highly absorbed by the body in the solid phase may thus be efficiently utilized.

Title: Non-contacting workpiece gauging system
Inventor: WILDER JOSEPH
IPC: G01B11/02
Filed: 1982-04-28
Abstract: A system for finding the position of a workpiece surface relative to a reference through non-contact gauging uses a radiant energy beam 18 projected such that an illuminated spot 20 moves along the workpiece surface 10a with movement of that surface relative to the reference 14 along a measurement direction 12a. An array-type image detector 22 detects the illumination at each of a number of small areas of the workpiece surface and generates signals representative of the detected illumination. These signals are converted into a test signal which is a function of the difference in overall illumination between larger areas of the workpiece surface. A reference signal is produced using a workpiece of known thickness and stored for two known positions of a workpiece surface. The test signal and the reference signal are combined with each other to produce a measurement signal indicative of the position of the workpiece surface relative to the reference. <IMAGE>
