Abstract: An intravenous catheter assembly comprises a catheter with an elongate hollow tube and a hub connected to the tube and having an interior cavity communicating with the lumen of the tube. A needle is slidably positioned in the lumen so that its point protrudes slightly beyond the distal end of the tube, whereas the other end of the needle extends through the hub and sealingly contacts the same so that the hub is effectively closed. A blocking device is contained in the cavity which is adapted to block the entrance of the lumen after the needle is withdrawn from the catheter tube to prevent ready re-insertion of an instrument into the lumen; however, flow of fluids into the lumen is not blocked. The hub includes an access provision to the cavity whereby fluids may be deposited into the cavity for delivery to a patient after the needle has been withdrawn from the catheter tube.

Abstract: A switching mechanism has disc cams arranged on a shaft for actuating switches positioned beside the shaft. The cam discs are adjusted exclusively by friction contact between these cam discs and at least one supporting member. The friction surfaces are held in contact with each other under pressure from a plate spring which is positioned outside of the pair of cam discs. The tension of the plate spring is selected so as to be great enough to ensure that the cam discs do not rotate relative to the shaft unintentionally, particularly when subjected to accelerations and impacts during operation. The tension is, however, at a level which allows a sliding adjustment of the cams with the use of a tool. The tension is preferably determined by the rate of the plate spring and a fixed axial spacing in which it is confined. This spacing is set, in the preferred form, by the length of a bushing of one support member that abuts an adjacent cam unit or an equivalent stop member.

Abstract: The invention concerns an electrolyte for use in a zinc halogen battery, which electrolyte contains an additive, which provides for improved zinc-on-zinc recovery. The improved electrolyte mixture involves a use of a lead additive to prevent unwanted film formation and diminish the nodular and dendritic formations on the electrode surface. The lead-containing mixture according to the present invention not only affects the morphology of the base plate zinc, but also the morphology of the zinc-on- zinc regeneration layer. Furthermore, such a lead- containing electrolyte mixture apparently lessens the formation of hydrogen.

Abstract: For use in low-voltage switchgear there is provided a plug-in contact device for connecting two bars, each of which has two confronting parallel contact surfaces. The contact device includes two co-acting elongated contact fingers which form two electrically parallel-connected current paths between the two bars. At the two end portions of the contact device the current paths intersect each other, whereas in a relatively long middle portion of the contact device the current paths are parallel and lie relatively close to each other, thus obtaining an electrodynamic contact pressure increase.

Abstract: The invention in connection with regenerative heat exchangers and ways of manufacturing them. The outer wall of the tubular rotor of such a heat exchanger is made up of one or more layers of an embossed aluminum strip that are fixed on edge and running radially outwards and in the form of a structure whose generatrix is a radius moving along a helical path, the structure being supported on an inner core. The embossing process is responsible for producing folds or puckers in the strip at its radially inner edge; furthermore the strip may have a stepped and/or waved form. Because of the helical coiling of the strip on a core, a rotor is produced whose outer wall may be used for the radial motion therethrough of flows giving or taking up heat.
