Title: Pellet media to support growth of microorganisms and systems for utilization of same
Inventor: VAN TOEVER JAMES WAYNE
IPC: C02F3/08
Filed: 1988-01-21
Granted: 2001-02-27
Abstract: Disclosed are pellets for use in a fluidized bed type of system to provide optimum surface configuration and maximum effective surface area per unit volume for the culture of microorganisms. The pellets are of low density, preferably plaster, having a buoyancy relative to the liquid in which they are fluidized substantially neutral or slightly positive. The pellets preferably have indentations on its surfaces to enhance the growth of microorganisms. The pellets are manufactured by either cutting discs from an extruded filament or punching discs from sheets of the appropriate material, with indentations being formed during the process.      Also disclosed is an aquaculture apparatus and system in which the pellets are preferably used. The apparatus includes a chamber in which the pellets may be fluidized within a liquid having dissolved elements to be processed, the chamber including apparatus to create fluidization of pellets within the chamber to induce movement of the liquid and pellets whereby self scouring of the pellets is achieved to limit the build up of biofilm thereon. In the preferred aspects, the apparatus and system pertains to water purification and in particular to the treatment of a dissolved toxic waste in an aquaculture system to non-toxic forms through the fluidization of the pellets containing biogrowth thereon. The fluidization is induced by an air bubble wash of the sides of the chamber, the air also aerating the liquid for return to a fish culture tank.

Granted: 1992-06-16
Abstract: ABSTRACT    In an apparatus suitable for using water-enamel, or some other similar conductive coating material, the particles of paint are sprayed from the grounded spraying edge of a bell-atomizer (2) and are charged in the corona-discharge area of the outer electrodes (10) which are inserted into a holding-arrangement (11, 12, 15) made of an insulating material.  By potential-control means in the form of suitably selected materials for the holding-arrangement and/or the atomizer-housing (4), the radial-potential pattern between the atomizer-housing (4, 6) and the outer electrodes (10) can be approximated to the radial-potential distribution of the material sprayed.  According to another aspect of the invention.  The insulating material of at least a part (4.11, 15) of the apparatus consists of a fluorocarbon such as PTFE (polytetrafluorethylene).  Both measures reduce the danger of the apparatus coating itself.

Title: Group control for elevators with load dependent control of the cars
Inventor: SCHROEDER JORIS
IPC: B66B1/20
Filed: 1988-08-26
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE         In this group control, a call firmly assigned to a car, but not serviceable at a stop at the respective floor due to an expected overload, can be serviced subsequently by the same car.  For this purpose first and second circuits, assigned to the floors, are provided.  A selector (R3) scanning the floor- and car call memories (RAM, lu, RAM ld, RAM 2'u, RAM 2'd) activates at every position the assigned first and second circuit, where the first circuit causes the car to pass the respective floor, if an overload would be generated at a stop.  The second circuits assigned to the upward- and downward direction are linked to each other in such a manner, that on establishment of overload the scanning by the selector (R3) of the floor- and car call memories assigned in each case to the calls of opposite direction is above all prevented.  After passage of the non-serviceable floor and reaching of the point of return of the direction of travel, the car therefore travels without interruption back to the (earlier) disregarded floor, whereby the blocking of the scanning of the floor- and car call memories of the calls in opposite direction is cancelled.
