Methods and kits for the isolation of organisms. Such methods and kits are particularly useful for concentrating and recovering viable organisms from food material. The recovered organisms are of sufficient number and purity to allow detection using a biochip device.

Toner concentration of an electrostatic developer is measured by disposing the developer between two electrodes and agitating the developer to produce electronic noise as a result of triboelectrification and measuring and determining from the generated noise the concentration of the developer.

A toner concentration detecting and toner replenishing system for use in an electrostatic copier having a magnetic brush which carries dry developer comprising a mixture of ferromagnetic carrier particles and toner particles into contact with the surface of a photoconductor upon which a latent electrostatic image has been formed, in which system a quantity of developer is removed from the magnetic brush after development of the image and the brush leaves the surface. The removed developer is dir...

A plant for tomato juice concentration uses a falling-film evaporator with an external sleeve which surrounds a vertical bundle of tubes divided into a plurality of sectors in which the tomato juice circulates in succession, and which is combined with a heat exchanger which is arranged externally of the evaporator and which is divided into a plurality of sectors in each of which the tomato juice is circulated and heated as it exits from a sector of tubes of the evaporator before being introduced...

The present invention provides a design for a PCRAM element which incorporates multiple metal-containing germanium-selenide glass layers of diverse stoichiometries. The present invention also provides a method of fabricating the disclosed PCRAM structure.

Hypolipidemic compositions containing 4-(2-thenoyl)-2,3-dichlorophenoxyacetic acid, its alkali metal salts or pharmaceutically acceptable base addition salts and methods of producing hypolipidemic activity by administering said compound. Combinations with other useful agents are also disclosed.

A method of, and apparatus for, the detection of particles or organisms, particularly faecal coliform, in which the fluid under test is dispensed drop-by-drop onto a moving absorbent surface. The surface is of such a nature, and/or is so treated that the organisms form discrete visible colonies which can be counted photo-electrically after incubation.

An apparatus and method provide measurement of a constituent of a fluid, such as ozone in ozonated water. The apparatus includes a vessel to contain the fluid, a light source configured to direct a first band of light and a second band of light along a substantially shared path though the fluid, and a photosensor that senses the first band of light and the second band of light. The constituent has a greater absorption associated with the first band of light than with the second band of light. Th...

Heat-sensitive, foamable liquids such as latex, are concentrated in a continuous process without foaming by feeding a heated liquid to a tubular evaporation chamber maintained at a reduced pressure where the liquid is adiabatically vaporized and forms an annularly flowing two-phase stream. The liquid and vapor phases are largely separated in the evaporation chamber by centrifugal forces acting on the stream. The final separation and isolation of the liquid phase is achieved in a separator consis...

A concentrator comprises a beneficiating member (1) in the form of a bowl with a tapered bottom (2) a concavity of which is provided with a discharge hole (13), and a drive mechanism (5) a hollow drive shaft (8) of which accommodates eccentrically a shaft (10) carrying the beneficiating member (1) executing a circular movement about a radius equal to the eccentricity. In cross section the bowl is elliptical and is connected to a base (3) by flexible elements (12), whereas the concavity of the ta...
