Abstract: A prosthesis that resiliently engages a body passage includes an annular clamping ring which may be folded along a diametric axis for insertion into the body passage. The clamping ring is adapted to resiliently spring outwardly, once in position inside the body passage, and to be continually resiliently biased against the interior surface of the body passage. One or more of the clamping rings may be attached to opposed ends of a tubular graft. The rings and connected graft may be positioned in the body passage using an applicator which selectively permits expansion and/or in some embodiments contraction of the annular ring in position within a body passage. Alternatively a retaining member may be used to retain the annular ring in a compressed condition until it is in a desired position within a body passage.

Abstract: An electromotor, in particular a drive motor for a barrel or container pump, having an outwardly encapsuled motor housing made of a material having good heat conducting characteristics, such as aluminium. The motor housing is provided on its outer side with a shield of an electrically non-conducting material. The shield is surrounded on its outer side with a mantle which forms, with the housing middle portion, a through-stream gap for the passage of cooling air. This outer mantle includes a pair of housing caps, which overlap the end-support shields of the motor housing, and between which housing caps there extends the mantle which shields the outer surface of the housing middle portion by forming the through-stream gap for the passage of cooling air. The outer shielding of the entire motor housing prevents contact with metallic parts and thereby current conducting parts of the motor by a person servicing the device.

Abstract: The barrel pump has at the lower end of its housing wall a sliding sleeve which--in the open position--exposes the inlet openings at the lower end of the housing wall and--in the closed position--in which it rests against a base plate, closes these inlet openings. The base plate projects in the radial direction beyond the housing wall and, consequently, closes the pump from below. Penetration by the liquid can, hence, only occur through the inlet openings provided on the periphery of the housing wall of the pump. Displacement of the sliding sleeve takes place in that at the underside of the sliding sleeve pressure pieces are provided, which in the close position project beyond the base plate downward and upon the pump being placed down due to the weight of the pump acting downward are displaced upward against the action of a spring acting on the sliding sleeve which frees the sliding sleeve from its sealing contact on the base plate and, consequently, permits entrance of the liquid through the inlet openings.

Abstract: The pump, specifically, barrel pump, can be equipped with exchangeable impellers (8, 8'), which can be screwed onto the lower end of the drive shaft (9). One impeller (8) is designed as an axial impeller, while the other impeller (8') is designed as a radial impeller. The radial impeller needs as intake orifice (37), which is easily exchangeable inside the pump foot. So that both impellers can be installed into otherwise identical pumps, it is necessary to select a larger distance between the impeller and the guide wheel in the case of the radial impeller than in the case of the axial impeller and to furnish the guide wheel with commensurately longer guide blades, which have, at the connection with the forward curved section, a long straight area parallel to the axis. Furthermore, the transportation channel inside the guide wheel is narrowed at the beginning and widens in the course of the axial flowthrough.

Abstract: A time-division multiplex switching network is constructed of units designed as time stages which operate blocking-free and which are multiply divided. A plurality of units of identical structure to a plurality of switching units of a switching network portion is assigned to each switching network portion, the plurality of units being operated as multiplexers at which the outgoing time-division multiplex lines are connected and whose normally non-utilized outputs can be connected by way of switches to other time-division multiplex lines extending from other switching network portions. Upon failure of the latter switching network portions, the switches are closed for rerouting the traffic through the system.
