Abstract: A sphere launching apparatus for selectively admitting spheres into a pipeline and comprising an angularly disposed support or track for storing a plurality of the spheres thereon, an access port at one end of the track for receiving the spheres therethrough for disposition onto the track, a discharge port at the opposite end of the track for discharging the spheres therefrom and injecting the spheres into the pipeline, the support member being interposed between the access port and discharge port for supporting the spheres in two parallel but offset substantially sequential relationship upon the track, and a release mechanism extending into the proximity of the support or track for alternate engagement with the leading sphere of each of the two parallel sequences thereof for releasing a single sphere at a time for passage through the discharge port for injection into the pipeline.

Abstract: A stuffing gland for shafts subject to relatively high pressures acting thereon in one longitudinal direction and comprising a flange disposed around the outer periphery of the shaft and having one side thereof open to the high pressure acting on the shaft, the flange being connected with the shaft for transmitting the force created by the pressure acting thereon to the shaft ina longitudinal direction opposed to the action of the high pressure surrounding the shaft, the area of the flange open to the high pressure being equal to the cross sectional area of the shaft for balancing the forces acting of the shaft for ease of operation of the shaft.

Abstract: A radiator having a header is cleaned by at least partially immersing the radiator in a cleaning liquid so that the header is immersed in the cleaning liquid and then applying ultrasonic energy to the cleaning liquid at an energy sufficient to cause cavitation of the liquid. The header is oriented in a direction toward the source of the ultrasonic energy, whereby the header is in closer proximity to the energy source than the remainder of the radiator, so that the ultrasonic energy is initially directed onto the face of the header.

Abstract: Rotary engine construction wherein a lobed rotor cooperates with unique retractable separators to divide the bore into work chambers, the rotor lobes or pistons performing the intake, compression, power and exhaust functions rapidly, efficiently and smoothly, and wherein the simplicity of construction allows the number of firings per rotor revolution, their sequence and the compression ratio to be readily selected for a particular end use. The engine further embodies novel intake and exhaust valves and actuating structure therefor, work chamber inactivation mechanism, and positive oil pumping means.

Abstract: A disposable cartridge or capsule for storing at least two independent ingredients preloaded therein in mutually sealed relationship, and selectively combining and mixing the ingredients to provide a substantially homogeneous compound. The cartridge comprises a sectional housing having mixer means rotatably mounted therein, said mixer means being carried by sealing means which cooperates with the housing for providing at least two sealed compartments therein in one position of the sealing means and opening communication between the compartments in a second position of the sealing means. Subsequent to a mixing operation, one of said housing sections may be separated from the other housing section and released from engagement with the sealing means and mixing means whereby the mixture may be stored in said removed housing section for use.
