Publication number: 20140042783Abstract: A transitioning device incorporating a rotatable platform supported on a base and having an elongated straddleable seat supported above the rotatable platform. A mechanism, either manual or powered, is provided to selectively rotate the rotatable base to facilitate moving a user to allow the user to transition from a first location to a second location angularly displaced from the first location. A user may desirably mount the seat when moving in a forward direction. Suitable hand rails and other support structures are provided to assist a user in mount and dismounting the seat. The seat may optionally be removable. Wheels or casters may be provided to facilitate moving the transitioning device. In one embodiment, a propulsion system may be included in the device. The fundamental functional concepts of the transitioning device may be combined with other devices to impart similar mobility benefits thereto.Type: ApplicationFiled: October 9, 2013Publication date: February 13, 2014Inventors: Richard A. St.Pierre, Fletcher W. Chapin, David W. Dranchak

Publication number: 20120118420Abstract: The present invention provides a family of devices insertable into a pipe or pipeline for counteracting the force and controlling the rate of flow of a fluid flowing in the pipe or pipeline. The disclosed devices have an overall shape resembling a spear to improve the fluid dynamic performance and are designed to be self-centering in a pipe. The devices can be made from readily available materials using well known manufacturing techniques. Other embodiments showing extensions to the invention are also disclosed.Type: ApplicationFiled: November 16, 2011Publication date: May 17, 2012Inventors: Richard A. St. Pierre, Fletcher W. Chapin

Patent number: 5908235Abstract: The present invention features an integrated, electronic fluorescent ballast fixture which includes an electronic ballast packaged with a set of fluorescent lamp connectors into an integral fixture. The fixture has a circuit board that selectably supports up to four fluorescent lamps. The housing of the fixture id configured to receive a number of lamp connectors. The connectors are electrically, connected to the circuit board use wire and poke-in type connectors. When used with conventional, straight fluorescent lamps, a second set of sockets at the far end of the lamps are also connected to the circuit board using wires received in poke-in connector on the circuit board. The integrated ballast package also works with U-shaped lamps. The housing of the fixture is shaped to accommodate projecting electronic ballast components attached to the circuit board. The transformers and transistors of the circuit board may be thermally sinked, so that their heat is carried to the housing by thermally conductive means.Type: GrantFiled: April 28, 1997Date of Patent: June 1, 1999Assignee: JRS Technology Inc.Inventors: James R. Petrozello, Fletcher W. Chapin, David W. Dranchak, Robert M. Murcko, Scott W. Knauss, Robert H. Katyl, John R. Susko

Patent number: 5259781Abstract: A connector assembly has a plurality of electrical circuit members and interposer frames with resilient contact members pressed together by a centrally located actuation screw. The actuation screw is supported within a threaded hole in an actuation bar on one side of one of the circuit members. Turning the actuation screw in its threaded hole causes various parts of the connector assembly to be pressed together simultaneously under an evenly distributed load. A load distribution plate located between the actuation screw and the nearest circuit member reduces the bending stresses in that circuit member. Alignment bushings and pins extending through openings in the circuit members maintain the various parts of the assembly in proper alignment while the actuation screw is being turned.Type: GrantFiled: November 18, 1992Date of Patent: November 9, 1993Assignee: International Business Machines CorporationInventors: John G. Baumberger, James R. Bentlage, Fletcher W. Chapin, Kishor V. Desai, Alan D. Knight, Thomas G. Macek

Patent number: 5248262Abstract: An electrical connector for interconnecting a pair of circuit members (e.g., a circuit board and module), which, in one embodiment, includes a housing, at least one flexible circuit within the housing and a spring means attached to the flexible circuit at two spaced locations for exerting force against the flexible circuit to cause the circuit to engage respective conductive pads on the circuit members when the circuit members are moved toward each other (e.g., compressed). The shape of the spring means conforms substantially to the portion of the flexible circuit between the locations of attachment. In another embodiment, a connector for interconnecting such circuit members includes a housing adapted for being located between both members and at least one elongated, compressible contact member in the housing and including conductive end portions for engaging the circuit members.Type: GrantFiled: June 19, 1992Date of Patent: September 28, 1993Assignee: International Business Machines CorporationInventors: Raymond A. Busacco, Chi S. Chang, Fletcher W. Chapin, David W. Dranchak, Thomas G. Macek, James R. Petrozello, George J. Saxenmeyer, Jr., Rod A. Smith

Patent number: 5237743Abstract: A method of forming conductive end portions on a flexible circuit member having a dielectric layer (e.g., polyimide) with at least one conductive element (e.g., copper) thereon. The method comprises the steps of forming (e.g., punching) an opening through both dielectric and conductive element, providing (e.g., additive plating) an electrically conducting layer on the opening's internal surface, providing (e.g., electroplating) a plurality of dendritic elements on the conducting layer's surface, and thereafter removing (e.g., punching) a portion of the dielectric and conductive element such that the formed dendritic elements (e.g., palladium) project from the flexible circuit's conductive ends.Type: GrantFiled: June 19, 1992Date of Patent: August 24, 1993Assignee: International Business Machines CorporationInventors: Raymond A. Busacco, Fletcher W. Chapin, David W. Dranchak, Jaynal A. Molla, George J. Saxenmeyer, Jr., Robert D. Topa

Patent number: 5163834Abstract: An electrical connector for interconnecting a pair of circuit members (e.g., circuit module and printed circuit board) which assures highly reliable yet separable connections for these members. The connector includes an electrically insulative (e.g., plastic) frame which defines an internal opening therein. Bridging this opening are a plurality of individual, resilient contact members which are maintained in a suspended and spaced orientation within the opening by a plurality of pairs of elongated insulative members (e.g., polymer rods). Each of the contacts is thus readily removable from the connector's frame to thus facilitate repair and/or replacement. As described, the connector is capable of providing wiping connections, thus assuring removal of debris or other contaminants from the respective conductive pads for each circuit member. In another embodiment, the connector includes a common carrier (e.g., plastic) having therein a plurality of cylindrical shaped resilient contact members (e.g.Type: GrantFiled: July 23, 1991Date of Patent: November 17, 1992Assignee: International Business Machines CorporationInventors: Fletcher W.
