Abstract: The invention comprises 1,3-dichlorotetra-fluorobenzene (a), 1,3-dibromotetrafluorobenzene (b) and 1-chloro-2,3,4,6-tetrafluorobenzene (c) and a method of preparing fluorinated aromatic compounds which includes the step of heating an aromatic compound, the nucleus of which is fully and exclusively halogen-substituted (at least one halogen being other than F), in a polar aprotic solvent with a dry fluoride of an alkali metal other than Li.  Specified solvents are tetramethylene sulphone, dimethyl sulphone, dimethyl sulphoxide and dimethylformamide. Hexachlorobenzene (or partially fluorinated hexachlorobenzene) gives various chlorofluorobenzenes including (a) and chloropentafluorobenzene (d); hydrogenation (Pd) of (a) gives (c) and 1,2,3,5-tetrafluorobenzene which on bromination gives (b). Reaction of (d) with the following agents gives the products indicated in parentheses: copper bronze (decafluorodiphenyl), alkali metal methoxide (methoxychlorotetrafluorobenzenes), alkali metal hydrogen sulphide (chlorotetrafluorothiophenols), ammonium hydroxide (chlorotetrafluoroanilines), hydrazine hydrate (chlorotetrafluorophenylhydrazines) and H2-Pd (pentafluorobenzene). Ullmann reaction of (b) with bromopentafluorobenzene (e) gives m-perfluoroterphenyl; (e) is obtained together with its dibromotetrafluoro and tribromotrifluoro analogues from hexabromobenzene. Octafluoronaphthalene, obtained from octachloronaphthalene, may be re-submitted to the method of the invention to attain higher priority.

Abstract: A control valve for automatically maintaining a constant rate of flow of a fluid through a pipeline includes a housing having therethrough a passage including an inlet opening and an outlet smaller than the inlet opening. An orifice plate is positioned within the passage adjacent the outlet opening, the orifice plate having therethrough an orifice. A regulating diaphragm is positioned within the passage at a location upstream of the orifice plate. The regulating diaphragm has therethrough circumferential ports and a central opening smaller than the orifice. The regulating diaphragm is formed of an elastic material such that the regulating diaphragm is deflectable toward the orifice plate in response to pressure differences across the control valve between a maximum deflected position, whereat the regulating diaphragm abuts the orifice plates, thereby closing the circumferential ports, and fluid flow is restricted by the central opening, and various positions whereat the regulating diaphragm is spaced from the orifice plate, thereby allowing fluid flow through the circumferential ports.

Abstract: A bottle cap of the tear-off type, particularly an easy-to-open cap for wide mouth bottles, in which a central top wall which covers the top portion of the mouth of the bottle is connected to a lateral band which surrounds the opening of the neck of the bottle and is bent under the edge of the neck to grip the cap, and a tear-off tab, bounded by one or more score lines, extends from the top wall through the lateral band and an angular sealing is interposed between the mouth of the bottle and the top wall and the lateral band. The angular sealing is bonded to the undersurface of the central top wall at a bond area inside the score line or lines, whereby, when the cap is broken by lifting the central top wall by means of the tear tab, the angular sealing is lifted with the central top wall in one piece and slips off from underneath the lateral band thereby freeing or loosening the lateral band from the mouth of the bottle.The sealing can also be bonded to the tear tab at the area bounded by the score line or lines towards the lateral band, to make the lifting of the sealing itself along with the central top wall easier, without breaking it.

Abstract: Described are new Saccharomyces cerevisiae yeast strains transformed withan  alpha -galactosidase gene (MEL<+>) using recombinant DNA methods. Baker's and distiller's yeasts producing  alpha -galactosidase are used in the corresponding industry because they are able to utilize the raffinose contained in molasses. This results in a greater yield of yeast (or ethanol) and in reduction or elimination of the costs associated with the biological oxygen demand (B.O.D.) in the effluent of factories. As a result of the improved ability of brewer's yeasts to produce  alpha -galactosidase a sensitive method for monitoring pasteurization of beer is provided. The new yeast strains prepared by using recombinant DNA methods produce more  alpha -galactosidase than naturally occurring alpha -galactosidase producing yeast strains. Also described are methods for marking yeast strains and for producing stable transformants of yeasts.

Abstract: The present invention is directed to recombinant genes and their encoded proteins which are recombinant flagellin fusion proteins. Such fusion proteins comprise amino acid sequences specifying an epitope encoded by a flagellin structural gene and an epitope of a heterologous organism which is immunogenic upon introduction of the fusion protein into a vertebrate host.

In a specific embodiment, attenuated invasive bacteria expressing the recombinant flagellin genes of the invention can be used in live vaccine formulations. The invention is illustrated by way of examples in which epitopes of malaria circumsporozoite antigens, the B subunit of Cholera toxin, surface and presurface antigens of Hepatitis B, VP7 polypeptide of rotavirus, envelope glycoprotein of HIV, and M protein of Streptococcus, are expressed in recombinant flagellin fusion proteins which assemble into functional flagella, and which provoke an immune response directed against the heterologous epitope, in a vertebrate host.

When possibly contaminated materials, such as blood, are being tested, the use of an evacuated tube allows the measurements to be made without the technician being exposed to the blood. The tubes are large enough to hold approximately one ml of blood, and are filled with an inert gas at low pressure. The floats are formed with a through bore (7) into which cell bands to be harvested will settle during centrifugation. The cell bands (A-E) are stabilized by a layer of a flowable material which settles onto the plasma layer during centrifugation and forms a pellicle thereon. The cell layers to be harvested are aspirated from the float bore by means of a hypodermic needle (131) or cannula inserted into the tube and float bore. <IMAGE>
