A wastewater treatment reaction vessel is operated with repeated sequences of aeration and non-aeration, using a single vessel or multiple vessels alternately, activated sludge which is acclimated for BOD reduction, nitrification or biological denitrification and phosphorus removal is absorptively reacted with influent wastewater, and the combined flow is passed into subsequent absorptive reactor ...

Aotus trivirgatus interspecies hybridomas, their monoclonal receptors and methods of preparation and use are disclosed. The hybridomas are prepared by fusion of Aotus antibody-producing cells with myeloma cells containing about an equal number of chromosomes per cell. The resulting hybridomas are stable and secrete Aotus receptors. Particular receptors that immunoreact with antigenic proteins of P...

Improved methods and novel compositions for enzyme complementation assays for qualitative and quantitative determination of a suspected analyte in a sample.

The invention relates to a method and device for fixing a joint prosthesis 1,2,5 where all surfaces intended to come into contact with tissue consist of titanium or a titanium-based tissue-friendly metallic material. For sure anchoring of the prosthesis into the bone tissue, pointed fixing elements 3,11,16 are used, which are driven with their points into that bone tissue intended to lie again...

The illuminating insert according to the invention is characterised by an unusually large reflector (2) by means of which the light from the batteries is supplied in its full extent to the entire interior (6) of the balloon.

An intravaginal contraceptive device (60) formed of a ring (62) having a central sheet (64) of resilient impermeable material sandwiched between two layers (72, 74) of foam rubber. The foam rubber traps sperm and bacteria in the vaginal recess for a time sufficient to be destroyed by the normal acid pH of the vaginal secretions. The ring (62) defines the sheet material (64) into a cup-shape with f...

A process for the preparation of liposomes which comprises spraying micro-fine droplets of a composition comprising substantially pure phospholipid in a volatile liquid carrier to impinge either upon or below an aqueous surface thereby forming liposomes at the said surface. The compositions may include drug molecules dissolved therein which are entrapped upon formation of the liposomes. The entrap...

A bundle of articles having at least one small dimension are cut in succession. Tension is developed on the top article of the bundle. Heat is applied rapidly to a seam of the top article to be cut. The separated parts of a top article are withdrawn from the path of the beam and the next article is exposed to the heat.

An ejector mechanism for multi-stage presses is disclosed. The pusher pin (3) runs inside of a slide (2). The pusher pin is supporter by a lever (6) on a cam curve (7) at the machine frame (1).
