Abstract: Water-in-oil priming emulsion vaccines increase the titers and/or avidity indexes of antibodies following a second dose of a commercial or experimental vaccine resulting in increased protection for disease in animal.

Abstract: Oil-in-Water emulsion vaccines induce higher biliary IgA responses which decrease mucosal/internal organ invasion and fecal shedding, increase specific activity of serum IgG subpopulations, and increase the relative avidity index of serum IgG subpopulations, resulting in increased protection from disease in animals.

Abstract: A method for extraction and concentration of antibodies, antigens, bacteria and virus from biological samples. The method also provides a preparation that is suitable for use as a vaccine. The method includes the addition of liquid carboxylic acids and a centrifugation step.

Abstract: A dust reduction system for reducing airborne contaminants such as, for example, dust, smoke, microorganisms, etc., includes at least one ion generator made up of at least one ionizer bar and a ground plane which is parallel and proximate to at least one bar. The system can also include a dust collection device such as a tray containing an aqueous composition optionally containing a degreaser, and/or a metal sheet with a water rinse system, and/or the surfaces of a room-sized enclosed space. The system can be applied to any enclosed space where it is desired to obtain high efficiency reduction of airborne dust and microorganisms. The system is especially useful in poultry production and processing areas such as hatching cabinets, throwing rooms, and controlled environment poultry rearing rooms.

Abstract: Avian diseases, particularly those which threaten birds early in life, are controlled by embryonal vaccination using water-in-oil-in-water emulsion vaccines. The site of inoculation is the albumin end of the egg via entry through the air cell end of the egg.

Abstract: A composition of a mixture of nonionic surfactants in water-in-oil emulsion vaccines allows the use of animal, vegetable, and synthetic oils as well as mineral oil and pristane. These non-mineral oil vaccines are as efficacious as mineral oil-containing vaccines without the problems associated with the use of mineral oil.

Abstract: Channel plate image intensifiers, for use as raster intensifiers in cathode ray tubes for example, comprise a stack of alternately arranged perforate laminar dynodes M and perforate laminar separators D aligned to form electron multiplier channels P. Each of the separators comprise a perforate aluminium plate having an anodized layer some 15 microns thick on the plate surface. Such separators can be manufactured to have the desired electrical characteristics and uniform thickness over their entire area so that the dynodes M are parallel to each other and provide a uniform gain over their entire area.The invention also relates to a method of anodizing perforate and imperforate aluminium foils.
