The inclined surface (23) of the slide (21) contains recess...

Appts. for the drainage of body fluids from the pleural cavity of a patient consists of a container (12) with a collecting chamber (14) and an inlet (16) for the fluid. Passages (34,38,24,46,56,72, 80,22,92,122,124) connect the chamber to a pipe (18) leadinq to a vacuum source. The valve (24) acts as a non-return valve and a controller (28) is used to adjust the amount of vacuum acting in the coll...

An elongated object such as a rolled steel section is adapted to be conveyed by means of a trolley supporting it at one end while the other end of the object is supported by a movable platform. The trolley comprises a frame of inverted U-shape to the legs of which are fixed a pair of wheels with a handle being attached to the frame and extending from the plane of the U-shaped frame. A subframe is ...

A surgical pleural drainage apparatus for draining fluids from the body of a patient is disclosed. The apparatus includes a container with a collection chamber. A suction outlet is provided on the container which is connected to a source of negative pressure and a fluid passageway connects the suction outlet to the collection chamber. A non-liquid one-way valve is provided in the fluid passageway ...

A diagnostic system wherein a central diagnostic center receives sensor data relative to the operating condition of a plurality of remote plants. Each plant records just certain sensor signals and transmits them at respective prescheduled transmisssion times. If certain activation limits are exceeded, a data link with the diagnostic center is immediately established so that the data may be transmi...

To continuously mix two flowable products such as a solid product in the divided state and a liquid product, two concentric ducts are provided each with associated entraining means. The entraining means of the outer duct serves to move a first one of the flowable products along the duct from an entry port towards an exit port for the mixed products and includes a helical element urging the first p...

Novel 5'-deoxy-5-fluoropyrimidine nucleosides are potent anti-tumor agents. Preferred compounds are 5'-deoxy-5-fluorocytidine and 5'-deoxy-5-fluorouridine.

A compound for the promotion of growth and/or milk production of domestic animals is obtained by coupling somatostatin or a homologue thereof, in the natural or oxidized state or in the pro-form or in the pre-proform, possibly over a bridging element, with at least one muramyl-peptide.

Selective esterification of only one of the hydroxy groups in polyols is achieved using an acetalized or a ketalized polyol as the starting material and an enzyme catalysing esterification. Furthermore, the selective esterified polyols may be obtained by concomitant acetalisation or ketalisation and esterification of a ketal or acetal in the presence of an enzyme catalysing esterification.

A redundancy circuit that consumes no power before or after activation switches a pair of output nodes from a first set of complementary logic levels to an inverted set when it is activated by blowing a pair of fuses.

A safety utility knife includes a handle, a blade fixed to the forward end of the handle, and a retractable sheath which is received within the handle. A mechanism is provided for automatically retracting the sheath within the handle by depressing a single button at the rear of the handle.

This invention provides a novel compound having a formula such as or This invention also provides a process for preparing such a compound. The novel compound has an excellent immunological activity.

Apparatus for gasifying a liquid with a fluid supplied in liquid form has a discharge conduit (40) for the fluid in which there are one or more restricted cross-section flow paths in a material providing a heat source for converting the fluid to a dry gas. Sealing means are urged resiliently against the open lip of a liquid-filled container (4) into which the discharge condurt projects. Control me...
