There are spiral fins (62, 64) disposed in the interior of the container (10) for imparting movement to the food products (66) at least in part along an axis of rotation of the container wh en the container is rotated about the axis of rotation. A temperature-...

An aqueous acidic trivalent chromium and fluoride containing coating (passivating) solution for zinc, zinc alloy and cadmium surfaces contains one or more complex compounds of the formula [Cr(H2O)6-xFx](3-x)+A- wherein x is an integer of from 1 to 3 and A is an anion of the group selected from nitrate, sulfate, phosphate, chloride, bromide, fluoride and iodide. In particular the solution contains ...

Prodrugs are prepared of the carbonic anhydrase inhibitors 2-benzothiazolesulfonamide, hydroxymethazolamide, and dichlorphenamide. The prodrugs link a water soluble compound to the pharmacologically active carbonic anhydrase inhibitor through an enzymatically or hydrolytically degradable bond.

The invention relates to the benzopyranone beta -D-thioxyloside compounds of the following formula as new industrial products: in which    - one of the substituents R or R' represents an oxygen atom doubly bonded to the ring carbon and the other represents a group R1    - the symbol --- represents a double bond conjugated to the CO group represented by one of the substituents R or...

A device forming a heat insulating wall structure for a fluid-tight tank and comprising an interposed joint packing including on each one of its sides at least one lateral joint consisting of a flexible and expansible heat insulating material accommodated within a corresponding recess of the packing body and connected to the latter, which joint after said packing has been mounted between two adjac...

The device can control an electric motor intended to rotate the drive shaft of a movable member, solar protection member, closure member or the like. The control device comprises a pulse generator device and an angular position coder, governed as regards rotation by the drive shaft, provided for supplying a signal permanently to a logic processing unit connected, through the intermediary of an inp...

NUCLEIC ACID DETECTION METHOD USING UNEQUAL PRIMER CONCENTRATIONS IN POLYMERASE CHAIN REACTION The detection of nucleic acids can be achieved with certain advantages in polymerase chain reactions by using primers in unequal concentrations. In particular, the molar ratio of a pair of primers is at least 2:1. Amplification of the nucleic acid of interest is carried out using standard reagents, but d...

An ink jet recording apparatus includes a liquid passage (112) for ejection of ink; a liquid chamber (108) for supplying ink to the passage; a device for mounting the recording head on the ink jet recording apparatus at an angle not more than 45 degrees relative to the horizontal plane; wherein the chamber (108) has an internal surface (105) which is slanted in a direction from an ink inlet (103) ...

A urine drainage bag having an outlet tube housing a microcidal tube is disclosed. The microcidal tube is manufactured from polymeric materials capable of absorbing and releasing antimicrobial substances in a controllable sustained time release mechanism, activated upon contact with droplets of urine, thereby preventing the retrograde migration of infectious organisms into the drainage bag.
