Abstract: A high temperature PVC resin blend is made by blend­ing from 60 to 85 parts PVC with no more than 40 parts of a ("alpha-SAN") copolymer of alpha-methyl styrene ("AMS"), styrene ("S") and acrylonitrile ("AN"), and less than 20 parts by wt additives including stabilizers, antioxidants, lubricants, and processing aids. In addition, an impact modifier may be added. The blend with particularly sized glass fibers, may be thermoformed at an elevated process­ing temperature and pressure, to provide a reinforced composite in which the PVC is covalently bonded to the glass fiber. The composite has a substantially higher HDT and equivalent tensile strength, compared to that of a similarly reinforced, unblended PVC composite, without sacrificing the novel composite's other desirable physical properties. The glass is sized with an aminosilane coupl­ing agent, and, a polymer film former selected from the group consisting of (i) a polymer with a nitrogen-contain­ing repeating unit such as an amine, amide, ureido, or urethane group, and (ii) a dispersible or emulsifiable epoxide polymer, which composite, upon extraction with THF, and a subsequent XPS examination, yields a Cl(2p)/C(ls) ratio of at least 0.91, and more preferably of at least 1.13. Glass fibers, thus sized, provide cohes­ive bonding of the resin, so the composite fails in cohes­ive failure. A unique sequence of mixing the blend ingred­ients with glass fiber provides optimum properties in the composite. The sequence requires formation of a single phase of PVC and alpha-SAN copolymer before dispersing the glass fibers in the blend.

Abstract: The invention concerns a safety cap, particularly suited to be tightened on containers having an essentially cylindrical shape and containing medicines or dangerous substances in general. 
     The cap (1) according to the invention consists of an inner element (10) which is tightened on the container (40), an outer element (30) placed over the inner part (10) and a central pushbutton (20) comprised between the inner element (10) and the outer element (30). 
     When the cap is turned in the tightening direction, the cap is closed; on the other hand, in order for it to be opened, it must be turned in the opposite direction, while pressing, at the same time, the central pushbutton (20) which acts as a trasmission element between the outer element (30) and the inner element (10). 
     The central pushbutton can be reached through a hole (37), which is made at the center of the flat top surface (38) of the outside element (30). 
     The hole (37) includes a safety seal consisting of a disc (60) connected with the outside element (30) by means of extensions (61) which will break under pressure. 
     The cap according to the invention presents limited radial overall dimensions and safety properties against the unwanted opening especially by children or handicapped people.

Abstract: The scraper for conveyor belts (1) comprises thin scraping plates (10) which are held in elastically prestressed scraper holders (7) arranged transversely with respect to the longitudinal direction of the belt. In this regard, the direction of force of the elastic prestressing force in the rest position of the conveyor belt (1) runs essentially perpendicular to the surface of the conveyor belt. The scraper holders (7) are mounted so that they can be deflected, with respect to a restoring device (18), both in the longitudinal direction of the belt and also in the longitudinal direction of the thin scraping plates (10). This results in individual matching, for example to different materials to be scraped, to different directions of movement of the conveyor belt (1) and to different surface characteristics of the conveyor belt (1). Advantageous configurations are additionally described. <IMAGE>

Abstract: A polycide etch process using a SiCl₄:HCl reactive gas flow rate ratio of at least about 1:1 for etching the polysilicon without etching, notching or degrading the overlying silicide. Thus, after patterning the silicide using a photoresist mask, the silicide can be used as the mask for etching the polysilicon, thereby providing precise pattern transfer to the polysilicon, independent of photoresist degradation. Also, a thinner, more precisely patterned photoresist mask can be used.

Abstract: The outputs of two filter channels for accepting two keying frequencies are compared to produce the output. Each channel uses finite impulse response transversal filters; preferably with an impulse response of duration comparable with the symbol period of the incoming signal. Each channel has a pair of filters for accepting phase quadrature components (or, alternatively, quadrature synchronous demodulators followed by filters): the filter coefficients differ from sinusoidal by (or, in the alternative case, are formed by) a modification function which is the same for both filters of the pair.

Abstract: In order to maintain resource integrity in a multiprocessing computer system wherein a local variable L which is accessible by a single process and a global variable G which is accessible by a plura­lity of processes and is dependent on the local variable L are updated sequentially and wherein the process may be terminated between the updating of the local and global variables, the expected value of the local variable and global variables are stored in first TL and second TG storage locations respectively before the local and global variables themselves are updated. If then, the process is terminated, a determi­nation of whether the process was terminated between the updating of said local and global variables can be made by comparing 91 the content of the first storage means TL to that of the local variable L and by comparing 91 the content of the second storage means TG to that of the global variable G and, if necessary, remedial action can be undertaken to correct the values of the variables.
