Abstract: An improved shallow speaker is disclosed having a molded diaphragm with an outer, depending, annular cylindrical subcone that connects to a channel formed in the outer perimeter of the spider. Embodiments for round and cornered (polygonal, etc.) speakers are provided. The top plate has a raised outer annular portion for receiving an annular spider flange with or without screw holes for clamping the inner spider flange with a spider ring. In the cornered speaker embodiments, flanges extend from the cylindrical portions to the cornered portions including from a diaphragm inner glue flange over the depressed central portion and from the annular cylindrical subcone both outwardly and inwardly to top diaphragm portions. Routing of the tinsel may be through one or more openings in the annular cylindrical subcone and along the diaphragm inner surfaces, with channels in or on those surfaces for securely routing the tinsel.

Abstract: The present invention is directed to a syringe filling station that can fill a syringe with a specified volume of fluid. In one embodiment, the syringe filling station comprises a reservoir attachment, a fluid delivery system, a syringe retaining guide, and a pump to move fluid from a reservoir to a syringe. The fluid delivery system may comprise a sterile consumable cartridge that is insertable into the filling station and defines a fluid pathway from a reservoir to a syringe. The syringe filling station may also include a user interface. An operator can input commands into the user interface to specify the amount of fluid to dispense into the syringe. The user interface may be connected to a processor that controls the rate of pumping and thereby can fill a syringe with a desired amount of fluid. The filling station may also include sensors that detect air in the tubing, depletion of the reservoir, among other things.

Abstract: This invention relates to a means of heating a process fluid to elevated temperature thru use of heat resistant particulates as a heat transfer medium. Down-ward flowing particulates, enter the top of a refractory lined containment vessel, and are heated to elevated temperature by direct contact with an up-flowing stream of hot combustion products, generated by side wall burners located at the bottom of the containment vessel. The heated particulate stream is separated from the combustion gas stream at the bottom of the containment vessel and the spent combustion gas is directed to a downstream tubular convection section for heat recovery and for further processing to recover vaporized process fluid, as in the case of liquid feed preheating for delayed coking, or for heat recovery only, as in the case of gas cracking.

Abstract: An embodiment of the invention consists of a process heater with a radiant section and an overhead convection section, the radiant section having a vertical cylindrical, contiguous, helical, tubular coil, having a bottom process fluid inlet and top process fluid outlet. The process fluid coil is contained in a refractory lined enclosure of square cross section and is exposed to an up flowing stream of combustion products, generated by burning coal on a continuous, traveling, chain grate stoker. The stoker is located at the base of the radiant section, receives a continuous deposit of coarse coal, with a minimum of fines, from a hopper located at one end of the stoker chain grate and discharges essentially coal free ash at the opposite end of the chain grate, thru a nozzle provided with a water seal.

Abstract: This invention relates to the design of direct fired heaters which consist of vertically oriented refractory lined enclosures containing tubular heat transfer elements, the elements partially surrounding a cluster of burners. The burners fire gaseous fuel and generate high temperature combustion products which allow for the transfer of heat , by radiation and convection, from the combustion products to the heat transfer elements and the continuous flow of process fluid contained therein. The transferred heat raises the temperature of the fluid from the design temperature at the inlet to the design temperature at the outlet, at a heat transfer rate commensurate with the temperature differential existing at any given location.
