A pump assembly for conventionally driven centrifugal pumps having a rolling element comprised of product lubricated ceramic or hybrid anti-friction bearings. The ceramic bearings are comprised of ceramic balls and ceramic races, whereas the hybrid bearings are comprised of ceramic balls with races made of another material. The ability of these bearings to perform well with poor lubrication allows the fluid that is being pumped to be used to lubricate and cool the bearings. An alternate embodime...

A building includes a rigid dwelling-house enclosing an inner space, a swimming-pool, and a device for moving the dwelling-house relative to the swimming-pool between a first position in which the dwelling-house is positioned on top of the swimming-pool which is thereby incorporated within the inner space of the dwelling-house, and a second position in which the dwelling house is adjacent the swimming-pool. The swimming-pool is usable as an outdoor swimming-pool or a covered swimming-pool, each ...

The present invention provides a rotary feeder system having a rotor housing with an intake opening and means for discharging material spaced apart side walls. A rotor is positioned with its radially extending blades disposed within the rotor housing and its two ends of its shaft each extending through an aperture in one of the side walls. The shaft bearing and interconnection to the rotating means are each disposed outwards of the rotor housing and the apertures are sealed about the rotor shaft...

An improved centrifugal pump having an integral pump/orifice plate located at either the pump discharge nozzle or suction nozzle for improved fluid flow measurements through the pump casing, and a process for measuring fluid flow through such a centrifugal pump casing is disclosed wherein the static pressure of a fluid being pumped by the pump is measured at a first point in the inlet or outlet area of the pump and at a second point removed along the nozzle, the pressures are compared to a pre-d...

At least one of the bottom element (10) and the top element (20) is provided with at east one recess (11, 12, 21, 22, 11a, 12a, 21a, 22a), into which...

A novel periodontal procedure for performing periodontal treatment including the steps of applying anesthetic to the area to be treated and making an incision on the facial side of the most posterior tooth and continuing the incision toward the most anterior tooth. The incision begins at the distal facial line angle of the most posterior tooth on the facial side of the arch and is made at about a forty-five degree angle to the plane of the tooth, forming an inverse bevel within the coronal porti...

An aqueous adhesive composition containing a graft copolymerized product of low amylose starch and acrylamide with rheological and remoistening adhesive properties suitable for coating low basis weight kraft paper on transfer roll coating equipment to make remoistenable sealing tapes. The desired properties of the adhesive composition are obtained by a controlled graft copolymerization together with a simultaneous gelatinization of the starch at temperatures below 210.degree. F. and with the ess...

The invention relates to an automotive cargo carrier utilizing interlocking vertically offset tubular perimeter members and multiple intersecting tension members providing for a substantially rigid, yet resilient structure, and a system for cargo carriage utilizing various interchangeable elements. The load support member was designed for use in conjunction with tubing members and has a universality of application in supporting the tubing members for load carrying purposes and can itself be so p...

A casting plant for low-pressure casting of molten metal with operatively and kinematically connected units in the form of linear or revolving conveying devices. The plant includes casting molds constructed and arranged to be filled with molten metal intermittently or continuously, and disposed either in a casting or residual metal receiving station or in a separate casting station, an insulated feeder pressure pot with a recompression unit and a shutoff valve unit having gas charging conduits f...

An apparatus for charging horizontal and vertical cold chamber pressure die-casting machines with metal, includes a pressure chamber having a first end which connects to a cold chamber pressure die casting machine, and an interchangeable receptacle, arranged underneath or laterally underneath the pressure chamber, the receptacle including a riser pipe which extends upwardly from a first end immersed in molten metal in the receptacle through a gas-tight cover on the receptacle to a second end. A ...
