Patent number: 5396211Abstract: A very small and thin transformer to be used as incorporated in an electronic device for the civil life. In this transformer, a coil is wound on a coil bobbin in which core sheets are incorporated as laminated. This laminated core is provided with an insulating cover for insulation. However, when a gap is produced between the core sheets, an adverse influence will be produced on the electric characteristics of the transformer. Therefore, in case the insulating cover is applied to cover the laminated core, the insulating cover having a resiliency will press the core sheets in the laminating direction to prevent a gap from being produced between the core laminations.Type: GrantFiled: January 27, 1994Date of Patent: March 7, 1995Assignee: Tamura CorporationInventors: Minoru Noguchi, Hiroshi Noda, Tetsuro Ishikawa

Patent number: 5385349Abstract: Three known devices for teaching golfers how to hold their clubs are structurally modified and used together as a set. The three devices are a lie indicator, a shaft position indicator, and a loft indicator. A record member is provided to record the information provided by use of all three of the devices as a set. After the three devices have been used on all of the golfer's clubs and the information provided has been recorded on the record member, further correct holding of the clubs may be obtained without further use of all three devices. Instead, the golfer merely needs to attach the shaft position indicator to each club shaft and the loft indicator to each club face, and to hold each club in the manner recorded on the record member. Accordingly, the lie indicator need not be used repeatedly, and the golfer need not remember the information recorded on the record member.Type: GrantFiled: January 25, 1994Date of Patent: January 31, 1995Inventor: Perry C.

Patent number: 5095792Abstract: A table top machine of box-like construction has a cutting mechanism in its interior and an entry bore that receives a microhematocrit tube. In a first embodiment, the end of a tube inserted into the machine closes a switch that activates the cutting mechanism so that tubes are always cut in the same place, without regard to the ratio of linear space in the tube occupied by red blood cells, clotted blood cells and clear plasma or serum. In a second embodiment, a photoelectric cell positioned at the inner end of the entry bore triggers the cutting mechanism when the end of the tube filled with red or clotted blood cells has passed the eye. Thus, tubes are cut at differing positions along the extent of the tube, depending upon how much each tube is filled with red blood cells or clotted blood cells and how much is filled with clear plasma or serum.Type: GrantFiled: December 4, 1989Date of Patent: March 17, 1992Inventor: Ernest Moody

Patent number: 5042636Abstract: Items carried by a conveyor belt are deflected from their original path of travel by deflector members that travel at the same speed as the belt, in some embodiments, or by deflector members that travel in a wave-like motion with the items in other embodiments. In all embodiments, the profile and preselected characteristics of each item are sensed and a computer determines which deflectors to deploy into path-diverting relation to the items. Thus, any pattern of deflectors can be deployed. The deflectors may be deployed gradually as they travel past a trigger member moving a slightly different speed or they may be deployed abruptly when traveling past a fixed position trigger member.Type: GrantFiled: March 26, 1990Date of Patent: August 27, 1991Inventor: Robert Underwood

Patent number: 5020284Abstract: A honing tool operated by a common motor or a drill while the part being honed is held by a common vice. A spring is positioned within a tubular sleeve member that is aligned with a boss member formed on the trailing end of a conventional housing for a conventional feedup rod. The leading end of the spring bears against the trailing end of the feedup rod and urges it continuously forwardly so that honing continues for as long as the spring is allowed to bear against the feedup rod. The honing operation can be stopped at any time by pulling back on a ring member that causes the spring to be compressed when pulled back. When the spring is compressed, the bias is taken off the feedup rod and hence the cutting stone, so that the diameter of the bore being honed can be measured.Type: GrantFiled: December 12, 1989Date of Patent: June 4, 1991Inventor: James G. Monahan

Patent number: 5014478Abstract: Track members of specific configuration are embedded in the edges of flat panel members. Extrusion members of specific configuration are employed to interlock the track members to one another in differing configurations. Each track member defines a cavity and in a first embodiment, two cavities are brought into abutting relation to one another to form a collective cavity into which a first embodiment of the extrusion member slidably fits. When so interlocked, the panels collectively form a wall or other surface. Additional embodiments enable the panels to be disposed at right angles to one another, to form "+" sign shaped intersections, radial arrays, and the like.Type: GrantFiled: September 22, 1989Date of Patent: May 14, 1991Assignee: Insulated Panel Systems, Inc.Inventor: Richard C.

Patent number: 5014630Abstract: A cremator having a parallelepiped construction of increased lateral breadth relative to earlier cremators. The hot gases flowing through the apparatus are constrained to follow a serpentine path of travel below the plane of the primary hearth that includes two return bends. Thus, the path of travel is elongated and the dwell time of the gases within the apparatus is increased. The gases are re-heated after the first return bend has been traversed, and the velocity of the flow of gases is further decreased by increasing the cross sectional area of the passageways that contain the gas flow.Type: GrantFiled: March 29, 1990Date of Patent: May 14, 1991Inventor: Steve Looker

Patent number: 5011489Abstract: A surgical tool for stripping the endothelium from varicose veins. A smooth probe member surmounts an elongate flexible wire and is inserted into the vein and withdrawn therefrom as a preparatory step. The smooth probe member is then removed from the wire member, and a smooth head member of frusto conical configuration is then mounted to the distal end of the wire. A plurality of barbed head members are then secured to the smooth head member, in longitudinal alignment with one another, distal to the smooth head member. The head members can be rigidly or flexibly interconnected to one another. The barbs on the barbed head members are swept back to facilitate their insertion into the vein and such barb members engage and strip the endothelium when the head members are withdrawn from the vein. The smooth head member is the leading head member during such withdrawal.Type: GrantFiled: October 5, 1989Date of Patent: April 30, 1991Assignee: University of South FloridaInventor: Mohamed E. M.

Patent number: 5007109Abstract: A flexible transparent lens that may be darkened to substantially block passage of bright sunlight is releasably or fixedly secured to the underside of a bill of an article of headwear such as a cap. In a first embodiment, buckles are affixed to the upper opposite corners of the lens and complemental snaps are affixed to the opposite rear corners of the bill. The lens follows the contour of the trailing edge of the bill when the snaps and buckles are engaged to one another. The top edge of the lens is spaced forwardly of its bottom edge when the lens is in its bowed configuration so that the bottom edge is closely spaced to the face of the individual wearing the head gear to thereby minimize the amount of sunlight reflected into the individual's eyes from reflective clothing and other sources of reflected sunlight. In another embodiment, the lens is riveted or stapled into position. In all embodiments, the lens may be clear or darkened.Type: GrantFiled: October 20, 1989Date of Patent: April 16, 1991Inventor: Robert L. Wheeler
