Abstract: A process for the preparation of an alumina-based extrudate suitable for use in the manufacture of a catalyst, comprises the steps of:   i) preparing an extrudable mixture comprising an alumina precursor, a cobalt, iron or nickel source and a solvent;   ii) extruding the mixture; and   iii) drying the so-formed extrudate.   The extrudable mixture may optionally comprise a promoter source. Alternatively, a promoter source may be deposited on the resulting extrudate. A catalyst is prepared by calcination of the resulting extrudate, which catalyst is useful in the preparation of hydrocarbons from methanol or a mixture of carbon monoxide and hydrogen.

Abstract: A method and apparatus are provided for injecting sealant into a packing assembly chamber surrounding a valve stem 11 of a valve 2 without venting the pressure within the valve 2. A cylindrical body 60 is frictionally welded to the exterior of the valve 2 adjacent the packing assembly chamber. A drill bit is passed into the body 60 and through a set of packing seals 87. An opening is completed into the packing chamber. As the drill bit is withdrawn from the body 60, a second valve 70 is manually "closed" to isolate the packing chamber from the drill bit and prevent the escape of pressurized fluid when the drill bit is removed from the seals 87. Thereafter, a device for injecting sealant is attached to the body 60 and the valve 70 is "opened" to allow the sealant to flow into the packing chamber.

Abstract: The cutting machine comprises a machine stand (10), a motor-driven cut-off disc (16) guided on a tiltable guide frame (14), a two-piece supporting table (26) for the workpiece (28), and a locking device for the tilting or pivoting movement. The part (42) of the supporting table (26) lying between cut-off disc (16) and guide frame (14) is firmly mounted and, when the pivotable part (30) is in a horizontal position, is flush with the latter. The tilting movement of the guide frame (14) can be transmitted via two lifting struts (32) projecting rigidly at right angles from the guide frame (14) and connected in an articulated manner to the pivotable part (30) of the supporting table (26). The lifting struts (32) lie in a horizontal position on both sides of the end faces of the fixed part (42) of the supporting table (26). The locking device fixes the guide frame (14) to the machine stand (10). The cutting machine according to the invention has a stepped supporting surface in the operating position for mitre cuts, and the cut-off wedges (28'') fall down and do not have to be removed until the end. The locking device for the cut-off disc (16) at the guide frame (14) can be set precisely and is free of play. A preferred embodiment with rounded-off guide tubes withstands high torque and still runs smoothly without cleaning work even during a prolonged operating period. <IMAGE>

Abstract: An inflatable cushion is organized into zones or compartments which are normally isolated from each other. The base of the cushion contains channels which lead from the several zones to a flap-type valve. When the flag is extended, the channels are connected through a manifold in the valve. However, when the flap is folded over upon itself, the channels are blocked before the manifold and the zones are isolated. Having separate and isolated zones, the cushion provides improved stability and better serves to maintain the user in a desired posture. A modification has individual fill valves and stems for each zone and for the manifold.

Abstract: An infusion pump (10) for infusing a medical treatment fluid intravenously to a patient includes a collapsible treatment fluid bag (18) juxtaposed with an inflatable drive fluid bladder (68) confined between a pair of opposing containment members (12, 14) which cause the bladder to impinge against the bag as the bladder is inflated. A drive fluid pump (72) controllably inflates the bladder, thereby displacing treatment fluid from the bag (18) into an outlet tube (20) affixed thereto which conveys the treatment fluid to the patient where it is recevied intravenously. The treatment fluid flow rate through the tube is controlled by increasing or decreasing the drive fluid pump output and consequently the pressure in the bladder in response to a pressure sensor (80) in fluid communication with the bladder. Alternatively, the treatment fluid flow rate is adjusted by opening or closing the outlet tube by means of an occluder or restrictor (26) positioned along the tube.
