A suction catheter has a conical extension (8) on the proximal side and ends in the pharynx space and serves for sucking up saliva, blood and gastric juice in the pharynx space. The catheter is fitted on the other curvature of the endotracheal tube. The arrangement includes a oropharyngeal tube (6) which movably encases the endotracheal tube and suction catheter, preventing them from being bitten ...

Wear parts of machinery have embedded within them optically recognisable elements, exposure of which is an indication of the state of wear. Corresponding wear parts, as well as wearing plates which slide on top of each other each have at least one element for indicating a state of wear. In the non-wearing reverse side of the wearing plates are embedded elements of material of up to the hardren of ...

The appts. to coat a moving yarn with paraffin, using a rotating paraffin body, has a bearing surface (32) rolling against the end surface (5) of the paraffin body.

A bearing assembly for guiding yarn 14 is mounted on a fixed shaft 4 and comprises an inner rotatable annulus 6, which is free to rotate about the shaft by means of rolling elements 8, and an outer rotatable annulus 10, which is free to rotate about the inner annulus by means of rolling elements 12. The outer annulus may carry teeth to grip the yarn. The assembly has a low starting torque.

The mechanism secures a curved flexible item (10) on the cylinder (2) of the printing press. It has a spindle turning in a groove in the cylinder parallel to the axis of the cylinder. The spindle is in several sections (14.2), each with teeth (17) at the periphery and by which it meshes with a spring-loaded (24) transverse rack (19). The latter is slid in opposition to the spring by an actuator (4...

Two winding spindles (5.1, 5.2) are mounted on the bobbin turret (18) of the winding machine. The particular winding spindle which is in operation bears with its bobbin against a contact roller (11). With an increase in bobbin diameter, the bobbin turret (18) is rotated in dependence on a slight deflecting movement of the contact roller (11). The position of the contact roller remains essentially ...

A tubular, rigid, porous, ceramic separator for a rechargeable, deep-discharge battery assembly, the separator having a porosity greater than 40%. A plurality of battery cells, each embodying such separators, are assembled with a common terminal to f orm the positive electrode in a motive traction battery.
