Abstract: An apparatus for removing injection molded articles from an opened injection mold of an injection molding machine. The apparatus has a low structural weight and provides exact control of the movements of a grasping member for grasping the injection molded articles. The apparatus has a guide bed and a carriage movably mounted on the guide bed. The guide bed is aligned parallel to the direction of operation of the closing unit of the injection mold. The carriage includes a cantilever which extends transversely of the guide bed. The cantilever carries a slide member longitudinally movable on the cantilever. An adjustable support member is mounted on the slide member. The grasping member is mounted at the lower end of the support member. The grasping member is adjustable relative to the support member about at least two joints extending perpendicularly to each other. In addition to the drive for the carriage and the drive for the support member, the drive for the support member is also mounted on the carriage above the guide bed. Accordingly, the weight of the drive for the support member does not rest on the cantilever, the slide member and the support member.

Abstract: A method and apparatus for early fault detection in a centrifugal pump equipped with a balancing device, where the balancing device has an axial gap and optionally at least one radial gap through which a balancing flow is conducted, and with a spring element which acts on the balancing device to hold open the axial gap. Reliable information regarding impending faults is obtained while largely using existing elements by measuring the deformation of the spring element (10, 14) during operation of the centrifugal pump (24), and starting from the pump characteristics of the centrifugal pump (24) and the spring constant of the spring element (10, 14), drawing a conclusion regarding the instantaneous operating state of the centrifugal pump based on the measured deformation.

Abstract: To measure a wide range of flow rates, and particularly such low flow rates as 0.5 liters per hour, while being able to accurately also measure rates of about 100 liters per hour, fluid is introduced axially into a rotor (14, 36, 40) which has outlet openings (24, 36, 45) positioned at their circumference, the rotor being rotated by reaction on the rotor upon fluid flow from the outlet openings. The rotor operates within a fluid flow chamber (15) from which is conducted outwardly through a duct positioned thereabove. Inflow of fluid may be guided for linear flow by guide ribs (13). The rotor may be a hollow disk-like structure (FIGS. 1-3) with spiral guide vanes therebetween, or a T-shaped tubular structure (FIGS. 4-6). If fuel consumption of an internal combustion engine is to be measured in which pressurized fluid is supplied to the engine and excess returned, two such flow meters can be combined on a common shaft, with respectively oppositely facing outlet openings (36, 45), so that differential flow only is being measured, hence accurately measuring fuel consumption by the engine. Rotation of the rotor is sensed by an electro-optical sensor (29, 37).

Abstract: A centrifugal pump comprises a casing which has two volutes disposed substantially diametrically opposite each other in such a way that the end of the first volute is adjacent to the start of the second volute. The outer diameter of the casing approximates or equals the diameter of the first volute in the region of the end of the first volute. This contributes to compactness of the casing. The volutes surround a rotary impeller or a guide wheel which is installed in the casing downstream of the impeller. Each volute extends along an arc of at most 180 degrees. The casing can have one or more elongated channels extending from the end of the first volute, along the second volute, and to a common outlet nozzle for both volutes.

Abstract: A centrifugal pump having an axial inlet and an inflow guide device mounted upstream of the impeller, which guide device is composed of several fixed guide vanes, which on the side facing the impeller each have an edge pointing in or opposite to the direction of rotation of the impeller. The edge pointing in or opposite to the direction of rotation may take the form of a swirl blade (8) which is formed on the guide vane (6) and located in the vicinity of the wall of the inlet (2), and which has a shorter radial length than the guide vane (6). This increases the efficiency of the pump and achieves an effect which increases the breadth of applicability of the pump.

Abstract: The double volute casing of a centrifugal pump has a main portion which has first and second volutes extending along arcs of not more than 180 degrees. The outer diameter of the main portion equals or approximates the outer diameter of the end of the first volute, and such end is adjacent to the start of the second volute whose end communicates with an outlet nozzle of the main portion. The latter has two channels which flank the second volute and extend between the end of the first volute and the outlet nozzle. The inner sides of the channels are open and face the axial passage of the main portion. Such inner sides are sealed from the axial passage by tubular inserts which are installed in and are separably fastened to the main portion of the casing. The passage receives a single-suction or a double-suction impeller or a stationary guide wheel which is located downstream of the impeller. The main portion of the casing is a one-piece casting.
