Patent number: 6743386Abstract: A vibratory apparatus and method for agglomerating chopped bundles of wet fiberglass strands into uniform segments includes a container having a curved inner surface disposed about a generally horizontal axis where the container is mounted on a plurality of springs. The chopped bundles of wet fiberglass strands to be agglomerated are placed onto the curved inner surface at an input end of the container. A vibratory force is produced to cause the chopped bundles of wet fiberglass strands to be moved from the input end toward an output end of the container. The vibratory force causes the chopped bundles of wet fiberglass strands to be directed in a rising and falling path of rolling movement within the container. As a result of the rolling movement of the chopped bundles within the container which is produced by the vibratory force, the chopped bundles of wet fiberglass strands are converted into uniform segments by reason of agglomeration of the wet fiberglass strands.Type: GrantFiled: April 30, 2002Date of Patent: June 1, 2004Assignee: General Kinematics CorporationInventor: Daniel T.

Patent number: 6453982Abstract: Apparatus for reclaiming sand is provided for removing impurities therefrom. The apparatus includes a vibratory conveyor in which the sand is fluidized and heated. The conveyor vibrates the sand to obtain a more uniform temperature. The apparatus may be used to clean used process sand, such as by pyrolyzing binder from foundry sand, or may be used to remove impurities from virgin sand, thereby minimizing the amount of silica which must be added to the virgin sand.Type: GrantFiled: July 27, 1999Date of Patent: September 24, 2002Assignee: General Kinematics CorporationInventors: Albert Musschoot, Daniel T.

Patent number: 6367959Abstract: A water blending apparatus for use in conditioning foundry sand. The apparatus creates a vertical sand stream flow path which increases the surface area of the sand stream and allows water to be applied to both sides of the sand stream rather than a single side, as known with conventional water mixing apparatus. In addition, the blending apparatus includes a housing inside which a pair of mixers thoroughly mix the wetted sand. Because the mixers are not positioned in-line with the main sand processing flow, as in conventional apparatus, the mixing time is not dependent upon the speed of the conveyor, and therefore mixing time may be increased. Furthermore, the agitators positioned inside the housing have a more efficient active area since a smaller clearance space is required than with over-the-conveyor style mixing devices, which must avoid contact with the conveyor belt. As a result, the sand may be cooled more quickly due to increased initial water coverage.Type: GrantFiled: February 19, 2000Date of Patent: April 9, 2002Assignee: General Kinematics CorporationInventors: Richard B. Kraus, Richard P. Kempf

Patent number: 6306337Abstract: A nosepiece for directing a charge into a crucible of a furnace. The nosepiece comprises a completely enclosed sleeve which more accurately directs the charge into the crucible. The sleeve has a distal portion that deflects the charge toward a center area of the crucible, thereby minimizing impact of the charge on the top edge of the crucible and its refractory liner. In addition, the nosepiece is split so that the distal portion is movable, thereby to provide access to an interior of the nosepiece. As a result, any bridging in the charge may be addressed by moving the distal portion to an open position.Type: GrantFiled: February 22, 2000Date of Patent: October 23, 2001Assignee: General Kinematics CorporationInventors: Richard B. Kraus, David A. Dawson

Patent number: 6286541Abstract: In order to provide a leak-proof coupling for a gas-carrying pipe having two pipe sections that are relatively movable, the coupling includes a first pipe section and a second pipe section that have respective coupling ends disposed in closely spaced adjacent relation to define a gap therebetween. The first pipe section has an upstream end in communication with a source of a pressurized gas and a first coupling end remote therefrom such that the upstream end receives the pressurized gas from the source and the gas then flows through the first pipe section from the upstream end to the first coupling end for discharge therefrom. The second pipe section has a second coupling end in communication with the first coupling end and receives the pressurized gas from the first pipe section and the gas then flows through the second pipe section from the second coupling end to the downstream end for discharge therefrom.Type: GrantFiled: November 3, 1997Date of Patent: September 11, 2001Assignee: General Kinematics CorporationInventors: Albert Musschoot, Oscar Mathis

Patent number: 6241951Abstract: In order to prevent material from passing into a plenum chamber, an assembly for fluidizing the material includes a deck supported above the plenum chamber. The plenum chamber has an intake in communication with a source of pressurized air, and the deck includes an inverted channel for distributing the pressurized air to the material in a preselected air distribution pattern and an inverted channel for supporting the material in a position generally above and in spaced relation to the air distributing channel. With this arrangement, the material supporting channel is disposed in spaced relation to the air distributing channel to permit the pressurized air from the plenum chamber to fluidize the material.Type: GrantFiled: July 31, 1997Date of Patent: June 5, 2001Assignee: General Kinematics CorporationInventors: Albert Musschoot, Richard B. Kraus

Patent number: 6237749Abstract: A motor base for use in vibratory apparatus. The vibratory apparatus includes at least one eccentric drive having a driven shaft rotatably mounted on a moveable exciter. A motor is provided having a motor shaft which is spaced from the eccentric drive and coupled to the eccentric drive by a drive belt. Rotation of the motor is transferred by the drive belt to the eccentric drive, which generates a vibrational force. The vibrational force moves the exciter in various directions during operation of the vibratory apparatus. The motor base comprises a rigid support, such as an arm, having a free end adapted to carry the motor. The arm is supported to move about an axis of the driven shaft, so that the arm maintains a center distance between the motor shaft and the driven shaft. A resilient support, such as a compression spring, is attached to the free end of the arm, below the motor, to absorb any resulting forces acting on the arm from the movement of the exciter.Type: GrantFiled: October 21, 1999Date of Patent: May 29, 2001Assignee: General Kinematics CorporationInventors: Paul Musschoot, Richard B. Kraus

Patent number: 6155404Abstract: A two-way drive for horizontally vibrating a feeder bed, including a reversible drive rotating one of two drive shafts rotatably connected so that the second drive shaft rotates at a speed which is a selected ratio (at least 2:1) of the speed of rotation of the first. A first eccentric weight is rotatably secured to the first drive shaft. A second eccentric weight is rotatably secured to the second drive shaft and movable between a first position on a first shaft radius when the second shaft is driven in one direction and a second position on a second shaft radius when the second shaft is driven in the reverse direction.Type: GrantFiled: June 18, 1999Date of Patent: December 5, 2000Assignee: General Kinematics CorporationInventor: Albert Musschoot, deceased
