Abstract: A method of trapping lubricant in a vacuum system and an assembly for performing same wherein a vacuum chamber has an outlet duct to a vacuum source to establish a gas flow path from the vacuum chamber to the vacuum source. Lubricant vapors from the vacuum source such as a vacuum pump are prevented from entering the vacuum chamber in accordance with the instant invention by establishing an electric field and subjecting the lubricant entering the vacuum outlet duct from the vacuum source to the electric field to electrically charge the lubricant and electrically attract the lubricant back toward the vacuum source. A magnetic field is also established between the electrodes to further urge the charged lubricant back toward the vacuum source. In this manner the lubricant is prevented or substantially prevented from entering and contaminating the vacuum chamber.

Abstract: A torque converter including a distortable rotatable center disc disposed between a pair of freely rotatable plate members. Roller elements are disposed between the center disc and the plate members. The roller elements are radially movable under the influence of centrifugal force for variably distorting the center disc in a wave-like fashion between deactuated and actuated conditions to rotate the plate members at a speed relative to the center disc in proportion to the amount of the distortion of the center disc.

Abstract: An air-circulating assembly includes a motor driven fan and a shroud supporting the fan. The assembly is characterized by a support structure for extending about and engaging an existing stove pipe for removably attaching the shroud to the exterior of the stove pipe so that the fan moves ambient air past the stove pipe to heat the ambient air.

Abstract: A vacuum chamber (10, 10') having first and second ends (28, 28') with a flow passage (30) at each end for directing the flow of particulate material into and out of the vacuum chamber. The vacuum chamber has a vacuum outlet duct (26) midway between the first and second ends (28, 28') thereof for removing gaseous contaminants. A flow control structure (32, 32') is disposed within the vacuum chamber (10, 10') between said first and second ends and has symmetrical ends for receiving particulate material from one of the flow passages (30) and directing the flow of particulate material to the other one of the flow passages while isolating the flow of particulate material from the surrounding space of the vacuum chamber through the central portion of the vacuum chamber adjacent the vacuum outlet duct (26) and for dispersing the particulate material while being subjected to the vacuum chamber adjacent the other one of the flow passages before the particulate material flows out the other one of the flow passages.

Abstract: A mold assembly and a method are disclosed for making a motion transmitting remote control assembly including the steps of; inserting the end portion of the conduit into a cavity of a first mold and injecting organic polymeric material into the cavity for molding the end fitting about the conduit, inserting the end fitting into a cavity of a second mold and injecting a vibration dampening material into the mold for molding a vibration dampener about the end fitting, and placing the vibration dampener into a cavity of a third mold and injecting an organic polymeric material for molding a support housing about the vibration dampener.

Abstract: A material injection assembly (10) of the type for injecting a resin material into a mold cavity including a body member (12) defining a nozzle (13) for injecting material into a mold (14) and including at least one central channel (16) for conveying a first material through the nozzle (13). The assembly is characterized by an internal purging mechanism for closing the nozzle (13) to the mold (14) while allowing the flow of purging material between the channel (18) supplying resin material to the control channel (16) and a debris channel (22). The purging mechanism further allows flow of purging material between a separate purging material channel (20) and the debris channel (22) to perform a post-purge function.A cooling system is also disclosed which provides a coolant supply channel (70) which bifurcates into two channels (75, 77) about the central channel (16) proximal to the nozzle (13) to provide maximum cooling at the portion of the assembly (13) closest to the mold (14).

Abstract: A closed loop assembly for dissolving a layer from an article by exposing the article to a leaching solution having a predetermined boiling temperature. The assembly includes a sealed reaction container including an inner compartment to contain the leaching solution and the article, a recirculation system connected to the reaction container for receiving boiled off leaching solution vapor and condensing the vapor and returning the vapor to the reaction container, and a heater for heating the article within the reaction container above the boiling temperature of the leaching solution.The assembly performs a method of dissolving the layer from an article by exposing the article to the leaching solution.

Abstract: A motion transmitting remote control assembly of the type for transmitting motion in a curved path including a flexible motion transmitting core element, a conduit for supporting the core element and an end fitting disposed at the end of the conduit. A rod is attached to the end of the core element. The assembly also includes a swivel tube having a bore therethrough for swivelling movement relative to the end fitting and for movably supporting the rod. The swivel tube is connected to the end fitting in a swivel joint. The assembly is characterized by the swivel joint including a male swivel portion of the swivel tube and including a cup-shaped insert engaging the male swivel portion at least beyond the front face thereof. The end fitting encapsulates the end of the conduit and the insert and the remainder of the male swivel portion on the swivel tube. A method of making the motion transmitting remote control assembly is also disclosed.
