Abstract: A control arrangement for supplying pressure fluid through a supply conduit from a source of pressure fluid to at least two hydraulically operated consumer devices includes, for each of the consumer devices, a valve having a valve member movable axially between a neutral position preventing flow of pressure fluid to the respective consumer device and two working positions respectively connecting the consumer device to the source of pressure fluid or a return conduit. A throttle is located in the supply conduit between a first point of the latter from which a first branch conduit branches off to a first of the valves and a second point from which a second branch conduit branches off to the second of the valves. The arrangement includes further a control valve and a control circuit therefor, controllable at least by the valve member of one of the valves. In the neutral position of all valve members the supply conduit is connected with the return conduit to form therewith a neutral fluid circulation passage.

Abstract: An inhalation device for self-administration to a patient powdered medicaments contained in a capsule. A chamber receives a capsule containing a powdered medicament. The chamber has a nozzle through which air from the chamber can be inhaled and the air inlet apertures leading into the chamber and so arranged that the air flow caused by inhalation through the nozzle will cause the capsule to be agitated. A magazine is slidable in the chamber to and from an operative position and is also rotatable in the chamber. The magazine has therein a capsule loading passage and at least one other passage. A capsule piercing needle and a capsule ejecting member are so arranged and positioned inside the chamber that the said passages can be registered as desired with either the needle or the ejector member on rotation of the magazine and so that movement of the magazine to the operative position will cause a capsule in a passage registered with the needle to engage the needle and be pierced by it and will cause a capsule in a passage registered with the ejector member to be engaged by the member thereby to displace the capsule from its passage into the chamber so that the powdered medicament from the pierced capsule can be aspirated through the nozzle by the inhalation of the patient.

Abstract: The bogies (2, 3) of a rail vehicle are connected to the body (1) of the vehicle by king pins or their equivalent (not shown), and also by transverse hydraulic actuators (11, 11a, 12, 12a), one at each end of each bogie. The actuators are interconnected by lines (21, 22, 23, 24) so that the forces exerted on, for example, the bogie 2 (forces P11, P12) act in opposite directions, and the effective piston areas of the actuators are so proportioned that the resultant of the two forces P11, P12 is a transverse force acting at a point halfway between the bogies. Similarly, the resultant of the two forces (P11a, P12a) acting on the other bogie (3) is a transverse force of the same magnitude, also acting halfway between the bogies, but in the opposite direction. The hydraulic system therefore tends to constrain the bogies to make equal but opposite rotations. <IMAGE>

Abstract: A method for operating a crushing and grinding facility is disclosed in which crushing of mine-run material is controlled to always match grinding feed requirements while both crusher(s) (10) and grinding mills (16) operate full time and draw full power during the hours of what may be unequal length working days. The grinding mill (16) is also operated to produce the maximum output of final product that is within its existing capabilities. At each of a succession of measurement times (e.g., every 1/2 hour during a 22-hour working day of the mill), the rate of production of final product by the grinding mill (6) is ascertained (as by 21, 22, 23) and projected to the end of the mill working day. At each such time, feed of mine-run material to the crusher (10) is adjusted (as by 27-33, 11) to a rate which, if maintained through the remaining portion of an 18-hour crusher working day, would cause production of a target quantity of crushed product (at 8) which would equal projected total daily production of ground product (at 9 ). However, the mill (16) will not maintain its prevailing rate of production because grindability of crushed material is unpredictably variable. Therefore, the projected 22-hour daily production of mill final product (at 9) is redetermined at the end of each time interval and is the bases for a new target for crusher production.

Abstract: A degreasing apparatus comprises a vessel (3) the lower portion of which is shut off by means of a bowl-shaped plate (5), to form a container (1) with a heating means (2) for boiling solvent. The bowl-shaped plate (5) has an opening (6) at its lowest point. A valve means (7) is arranged at the opening (6). The valve means (7) comprises a body, preferably a ball, which can seal against a seat which surrounds the opening (6). The density and size of the body are related to the size of the opening (6) so that the body floats up from the seat in the presence of solvent condensate, so that condensate can pass from the valve means to the container (1). Vapor pressurized in the container (1) by the heating means (2) lifts the body from the seat so that vapor can flow up into the treatment space of the vessel (3). When the apparatus is shut off, the body seals the opening (6) and thereby prevents evaporation of solvent from the container (1).

Abstract: The aim of the invention is to determine the plastic deformability of ceramic materials so that they can be mutually compared and to determine the optimum deformation parameters. The object of the invention is to provide a piston compression system which makes it possible to determine the variation in the degree and pattern of deformation with respect to distance and time. According to the invention, a vertically swivellable frame is mounted on a cabinet-type stand. In its turn, the frame carries a hydraulic test cylinder which interacts with the test cylinder via interlocking linking elements. The test cylinder has a fixed piston having a central nozzle-type outlet for material. The test cylinder piston rod is provided with a groove-type, longitudinally directed recess for receiving the strand of material. The test cylinder can be driven optionally at constant speed or constant pressure by means of working cylinders via a pressurised hydraulic system.

Abstract: The present invention relates to an assembly and a method for feeding electrodes which are used in electrothermic smelting furnaces. The electrode comprises an electrode casing having vertical ribs projecting radially outwards from the casing. A plurality of electrode feeding units, each including a clamping means are arranged around the periphery of the electrode and each clamping means exerts a releasable pressure on a rib, the clamping means imposing only tangentially forces on to the electrode. When feeding the electrode, the pressure on one of the clamping means is temporary released and the clamping means is moved in vertical direction relative to the electrode, whereafter the pressure on the clamping means is reactivated. This is done for every electrode feeding unit with a preset time-delay between the movements. When all the electrode feeding units have been moved one at a time, all the electrode feeding units are moved together in vertical direction. The clamping means are formed of two substantially identical reversed parts which are hinged around a central member.
