Decanter-type separating apparatus comprising within a rotatably mounted tapered and cylindrical barrel a solids-transporting screw rotating at a speed different from the barrel speed, the aforesaid apparatus being characterized by the screw having in an intensive clarification region a pitch substantially greater than used in the past, to stabilize the flow as far as possible and to obtain partic...

A process for the preparation of a known pesticidal alpha -cyano-3-phenoxy-benzyl 3-alkenyl-2,2-dimethyl-cyclopropanecarboxylate of the general formula (I) in which R1 and R2 independently of each other represent a hydrogen or halogen atom, R3 represents a hydrogen or halogen atom or an optionally substituted alkyl group, and R4 represents a halogen atom, an optionally substituted alkyl...

Plasmapheresis by filtration can be carried out with high efficiency for long periods by conducting blood over a surface of a membrane and passing plasma at an accelerating rate until the threshold level is attained, maintaining the rate of passing plasma until the ceiling system transmembrane pressure difference is attained and then reducing the passing of plasma and the system transmembrane pres...

1. An apparatus for pumping liquids, comprising at least a centrifugal pump (9) including an impeller (15) having radial blades axially delimited by an end flange, said impeller being driven by a bidirectional motor (12), and including an air supply duct (18) in communication with the interior of the housing of said pump, characterised in that the impeller (15) carries main blades (21) which are r...

Application of a compete compress, for e.g. a compress stocking, compress arm, on an extremity without a gliding movement between the bandage and the extremity in question is required for thin skin or open wounds, when the bandage of the actual wound must not be touched. Rubbing and dragging movements on the skin of these patients can be very painful. Glide stockings with little friction and which...

The prop can be used as a corner support for a lorry canopy frame, and comprises a supporting member with a fixing device and a coaxial telescopic extension piece. A locking device secures the two in position in relation to each other. - A spring mechanism, between the member and the extension piece, moves them or allows them to move in relation to each other. The locking device can be freed from ...

The invention relates to an arrangement for securely locking a container holding valuables, for example a case 1, onto a base. The bottom of the case is provided with feet 3, 4 which are operationally coupled to an alarm device or safety device incoporated in the case, for example for staining valuable documents with dye in the event of unauthorized handling of the case. Each foot has a recess 5 w...

The spray mouthpiece is for spraying dirty dishes with fluid, and is fitted in a hole in the wall of distribution channel or box, from which the fluid is pressure-fed to the mouthpiece. The mouthpiece is formed as a nipple with a fixture arrangement in the hole, and a spray aperture outside the wall. - The spray aperture is formed as a track (17) at right-angles to the central axis (21) of the nip...
