Patent number: 4551040Abstract: The outlets of pneumatic pipes in a transporting unit which delivers filter rod sections from a filter rod making machine and wherein the sections move axially admit successive sections into a separating unit wherein the speed of sections is uniformized and the sections are separated from each other by clearances of preselected length prior to entry into the corresponding channels of a deflecting unit which changes the direction of movement of each section from axial to sidewise movement and directs the sections into a junction zone. The latter admits a multi-layer stream of parallel sections which move sideways onto the upper reach of an endless belt conveyor which delivers the stream to a processing machine. The speed of the conveyor is regulated in dependency on the rate at which the deflecting unit receives sections from the separating unit so that the rate of delivery of sections to the processing machine matches the rate of delivery of articles to the separating and deflecting units.Type: GrantFiled: June 17, 1980Date of Patent: November 5, 1985Assignee: Hauni-Werke Korber & Co.

Patent number: 4391860Abstract: The invention contemplates a powder-feeding system for gas-propelled delivery of a powder to be controllably supplied, as to a flame-spraying gas torch or to a transferred-arc plasma torch. A fluidizing chamber receives (a) fluidizing-gas flow from below a porous screen, and (b) a restricted gravitational flow of powder at a relatively small central discharge location above the porous screen. A gas conduit extends transversely through the chamber between the powder-discharge location and the porous screen; it has a carrier-gas supply connection at one end and a gas-propelled powder-delivery connection at its other end. The conduit also has an upwardly extending opening virtually beneath and facing the powder-discharge location, but a shed interposed between this opening and the powder-discharge location sufficiently overlaps the opening to assure that no powder will pass through the opening and into the conduit unless it has been gas-fluidized.Type: GrantFiled: February 23, 1981Date of Patent: July 5, 1983Assignee: Eutectic CorporationInventors: Anthony J. Rotolico, Eduardo Romero, John E. Lyons

Patent number: 4379663Abstract: A weight sensitive arrangement for controlling the material draw cycle of a vacuum sequencing system based on the weight of material delivered to a pellet receiver included in the system. The material is drawn by a vacuum into the receiver under the control of a dump valve. The receiver deflects downwardly when loaded and is equipped with a U-shaped deflection beam having an upper arm that deflects in proportion to the receiver deflection. A screw carried on the upper arm of the beam contacts a microswitch when the receiver is loaded to a preselected weight. The microswitch then activates the dump valve to interrupt the vacuum, thereby terminating the material draw cycle and effecting discharge of the batch of material in the pellet receiver.Type: GrantFiled: September 22, 1980Date of Patent: April 12, 1983Assignee: Mac Equipment, Inc.Inventor: Robert Allison

Patent number: 4319782Abstract: To limit the amount of solid particulate matter fed into an airlift pipeline from, especially, a suction nozzle device, the density of the suspension passing from the suction nozzle to the airlift system is measured. If the measured density is above a predetermined value, a proportion of the suspended solid material is removed prior to passing into the airlift pipe.The density of the moving suspension is determined by a radiation-type densitometer located upstream from the airlift pipe. The density can also be directly measured by a balance beam or weighing arrangement connected to a pivotable length of pipe. Where fine particles are present that are not to be considered in the densitometer measurement, a differential measurement can be obtained by a second measurement of the density of liquid from which the large particles have been screened.Type: GrantFiled: June 6, 1980Date of Patent: March 16, 1982Assignee: Deepsea Ventures, Inc.Inventor: John P.
