Abstract: A rotational exercise apparatus (10) for strengthen and toning the human body which consists of a collapsible stationary support frame (20) with horizontal gripping arms (22) and a base plate (52) attached in a horizontal position to the frame. A rotatable platform (54) is positioned on top of the base plate and freely rotates with a pair of swiveling foot plates (56) mounted on the platform upper surface. During use, a person places their foot on each foot plate (56) and exercises by rotating and counter rotating both the platform (54) and the foot plates (56) simultaneously while maintaining balance by holding onto the gripping arms (22).

Abstract: An orbital resistance-adjustable sphere exercising apparatus (10) that is designed to allow several exercise routines to be performed through several planes and range-of-motion at selectable friction levels. The apparatus (10) consists of four major elements: a sphere cradle (12), a sphere (116), a set of three sphere friction pads (42, 54, 94) and a telescoping pole assembly (126). The sphere cradle (12) includes a base (14) that has attached three sphere support frames (32, 52, 92) that are evenly spaced and that each have attached the friction pads (42, 54, 94) that interface with and support the sphere (116). The sphere cradle (12) also includes a sphere friction adjusting rod (104) that when rotated clockwise the three sphere support frames (32, 52, 92) simultaneously extend inward allowing the friction applied by the three friction pads (42, 54, 94) to the sphere (116) to increase. Likewise, when the rod (104) is rotated counter-clockwise the applied friction is reduced.

Abstract: The current apparatus is a chair assembly comprised of a plurality of structural, pivotal, sensor, and material designs to provide for the comfort and health of the user. The frame provides the user with substantial support along the entire region of the user's body. The frame adjusts, both vertically and horizontally, via adjustable ball joints which operate in conjunction with the body joints. The frame, in conjunction with interchangeable hand modules, attachments, and accessories, allows for resistance exercises via use of manual tension springs. Contoured pads mounted along the frame contain a plurality of sensors to pick up signals from various regions of the users body including muscle, bone, nerve, O2, and load. The data is collected and analyzed by a computer providing for corrections in chair adjustment and exercise resistance instruction with recordation of all activity to facilitate healing and documentation of treatment.

Abstract: A method for high speed spin winding a coil on a continuous lamination core. A two piece or hinged bobbin having two flanges is placed around a leg of the transformer core and snapped together. Both flanges include an outwardly facing surface which defines a concentric groove. One flange includes passages for receiving printed circuit board terminating pins which are installed prior to winding the coil. The other flange has a circumferential gear located in its outwardly facing surface. The core with bobbin and terminating pins installed is placed into a spin winding fixture. A bobbin bearing having a bearing surface including a circumferential ridge is placed adjacent the outwardly facing surfaces of the two flanges such that the circumferential ridges are partially received within the concentric grooves of the outwardly facing surfaces of the two flanges. A wire feeder terminates the leading end of the coil wire on one of the terminating pins.

Abstract: A method of assembling a three phase current transformer for printed circuit board installation. Three current transformers, each having a spin wound coil positioned about one leg of an unassembled continuous lamination core, are placed side-by-side in a transformer carrier such that two parallel core legs of the center transformer overlap the adjacent core legs of the two outside transformers and further such that printed circuit board terminal pins attached to the coils pass through stand-off sleeves formed from the transformer carrier. Rivets are placed through holes in the laminations of the overlapped core legs and in the transformer carrier thereby simultaneously riveting the three transformer cores and the transformer carrier together making a three phase transformer assembly.

Abstract: A bearing for maintaining a bobbin in relative position about a transformer core leg during the winding of a coil on the bobbin. The bearing is movable along the core leg such that a bearing surface of the bearing is positioned adjacent to but not touching each of two outwardly facing surfaces of two spaced apart flanges of the bobbin. The bearing surface is highly polished to reduce friction. The bearing surface preferably includes a circumferential ridge centered about the axis of the transformer core leg on which the bobbin is positioned. The outwardly facing surfaces of the two flanges each include a concentric groove shaped to complement the circumferential ridges of the bearing surfaces. When the bearing is in position the circumferential ridges are partially received within the concentric groove such that a small gap is maintained between the bearing surfaces and the outwardly facing surfaces.

Abstract: A method for laminating a magnetic core of a three-phase current transformer uses a continuous length of magnetic metal material and a mandrel having first, second, third, and fourth sets of pins mounted to a mandrel plate. The second and third pin sets are located adjacent one another, adjacent the respective first and fourth pin sets, and between the first and fourth pin sets. The third and fourth pin sets are movable between a retracted position within the mandrel plate and an extended position extending from the mandrel plate. The third and fourth pin sets are first positioned in the retracted position, and a first portion of the length of magnetic material is wound about the first and second pin sets to form the first phase section of the magnetic core. After moving the third pin set to the extended position, a second portion of the length of magnetic material is wound about the first and third pin sets to form the second phase section.

Abstract: A method for manufacturing an electrical switching contactor provides a more effective electro-magnetic pulling force in a smaller sized package. The method includes forming at least two adjacent closed-loop laminated metal cores from a substantially continuous length of magnetic metal, providing a coil bobbin separated into first and second sections through a vertical axis, arranging the first and second sections about a center portion of the closed-loop laminated cores, such that the center potion includes a part of each adjacent closed-loop. A coil is wrapped around the coil bobbin, and the coil bobbin is arranged with respect to the coil to electrically insulate the coil from the adjacent closed-loop laminated cores.

Abstract: An improved power-switching relay especially designed for mounting on printed circuit boards together with a method for manufacturing such a relay. The relay includes a number of features designed to properly position the various relay components relative to one another and to help ensure that they remain in the proper position at all times. To this end, the relay includes a unitary bobbin (22) and stationary contact support header (33) together with means (64) for firmly retaining the stationary contacts (34, 36) and their terminals (63, 73) in place in the header. The relay also provides means to prevent rotation of the armature relative to the movable contact assembly (53, 54) and to prevent rotation of the coil assembly relative to the frame (35). According to a further aspect of the invention, the core and coil assembly is attached to the relay frame by extending the core through the coil assembly and press-fitting the core into an extruded hole (14) in the frame.

Abstract: A relay adapted to be mounted on a printed circuit board, and a method for mounting such relays. The relay includes the usual terminals (23, 24, 26 27, 28, 29) extending therefrom and adapted to be mounted on a printed circuit board (30) and electrically coupled to conducting paths on the board. In addition, however, the relay is provided with additional load terminals (56, 59, 62, 82, 92) which function as external connection junctions to connect the relay directly to the load being controlled via a circuit that completely bypasses the printed circuit board. According to a preferred embodiment, the relay includes stationary contact members formed to have not only board-mounted terminal portions extending therefrom but also external terminal portions for direct attachment to the load.
