Patent number: 10287111Abstract: An activated roller transfer apparatus for transferring articles between one conveyor and another. The roller transfer apparatus comprises a linear-induction-motor stator as a primary and electrically conductive article-supporting rollers as a secondary. The linear-motor stator generates a traveling magnetic flux wave that induces eddy currents in the rollers. The eddy currents produce magnetic fields that interact with the flux wave to produce forces that rotate the rollers to propel articles across a gap between the ends of the two conveyors. The stator is generally trapezoidal in shape to comport with the shape of the gap.Type: GrantFiled: January 12, 2016Date of Patent: May 14, 2019Assignee: Laitram, L.L.C.Inventors: B. L. J. Gysen, J.

Publication number: 20100289457Abstract: A method of providing power to an electronic device in an energy-efficient manner includes transitioning between power states corresponding to charging and discharging a battery. The state of charge of the battery is detected. Upon detecting a high threshold state of charge, an external power source such as an AC-to-DC adapter is disabled, and the battery to provides primary power to the electronic device. Upon a low threshold state of charge, the AC-to-DC adapter is controlled to provide a high current output to charge the battery and provide primary power to the electronic device. The power states, when cycled over time based on the state of the battery, provide for an energy-efficient method of powering the electronic device.Type: ApplicationFiled: May 17, 2010Publication date: November 18, 2010Applicant: Boston-Power, Inc.Inventors: Per Onnerud, Phillip E.

Publication number: 20080128053Abstract: In a method for preparing a welded metal panel having a high surface quality a first metal blank and a second metal blank are disposed so that edge portions of the blanks are in an abutting relationship. The blanks are laser welded together utilizing a powdered metal filler so as to produce a weld seam which is convex. A portion of the seam is removed to produce a flush weld seam between the blanks. The hardness of the weld seam is determined, and if the hardness of the weld seam is more than the hardness of the remainder of the panel, the weld seam is tempered so as to reduce its hardness. The thus produced welded metal panel may be subjected to a further shaping operation such as stamping, bending or the like. After shaping, the article may be plated, painted or otherwise finished.Type: ApplicationFiled: December 5, 2007Publication date: June 5, 2008Inventors: Steven W. Jansen, Kevin P.

Patent number: 5743248Abstract: A portable, fused essentially waterproof campfire is presented. The campfire has a trapezoidal cross-section with kindling, a firestick and a fuse located near the bottom center of the trapezoid. The fuse runs from the firestick to the outside of the campfire. Surrounding the firestick and kindling are increasingly larger sizes of wood, ranging from one inch in diameter to approximately 5 inches in diameter at the top. The campfire, once constructed, is entirely surrounded by a clear combustible material such as shrink wrap and a handle is attached. The shrink wrap not only keeps the campfire in its trapezoidal shape, it also keeps water from penetrating. The campfire is highly portable and easily started even under damp conditions. One simply lights the fuse, which ignites the firestick and kindling and the rest of the fire.Type: GrantFiled: November 13, 1996Date of Patent: April 28, 1998Inventor: Herman W. Jansen, Jr.

Patent number: 5027292Abstract: A CSG solid modelling system 10 has a triple z-buffer architecture. For each pixel stored in a pixel memory 12 there are five storage entries grouped into five buffers including a front z-buffer (F) 16 which is employed to store the depths of a front face for a currently processed z-connected product, a back z-buffer (B) 18 which is employed to store the depths of a back face for the currently processed z-connected product and a final z-buffer (Z) 20 which stores the front faces of a displayed solid. Two other buffers are an intensity buffer (T) 22 for storing the intensities associated with the front face of the current z-connected product and a final intensity buffer (I) 24 for storing the intensities of the visible faces of the displayed solid. A bus 26 couples these various buffers together and to a processor 28 which may be a central processing unit or a peripheral processor.Type: GrantFiled: April 19, 1989Date of Patent: June 25, 1991Assignee: International Business Machines CorporationInventors: Jaroslaw R.

Patent number: 5014421Abstract: A blade having a concavely shaped leading edge is cut. The blade has first and second side faces, a tip profile and a root profile. Each profile has a first and second profile side corresponding with the first and second side faces. The cutter is positioned between the first root profile side and the first tip profile side. The tip profile and root profile are followed with two cutter portions of the cutter along the first root and tip profile sides toward the leading edge to cut the first side face. One of the cutter portions is translated around to the second profile side before the other cutter portion is translated to the second profile side, causing the formation of the concave leading edge. The tip and root profile is followed with the cutter, along the second profile side away from the leading edge to cut the second side face.Type: GrantFiled: December 26, 1989Date of Patent: May 14, 1991Assignee: Ingersoll-Rand CompanyInventors: M.

Patent number: 4861493Abstract: Process for the removal of metals, in particular heavy metals and strontium, from waste water in the form of their sulfide by mixing the waste water with a water soluble sulfide. According to the invention the metal containing waste water is thoroughly mixed with the water soluble sulfide at a suitable pH in a reactor of the fluidized bed type, which is provided with an appropriate bed material, on which the metal sulfide crystallizes out, whereby the thus obtained bed material provided with crystalline metal sulfide is removed from and new bed material is added to the reactor from time to time. Usually as water soluble sulfide an alkali metal sulfide or alkali metal hydrogen sulfide or ammonium sulfide or FeS is used, whereas the use of sodium sulfide, sodium hydrogen sulfide, potassium sulfide or potassium hydrogen sulfide is preferred. According to the present process a.o. the following metals: Ni, Sr, Zn, Cu, Fe, Ag, Pb, Cd, Hg, Co, Mn, Te, Sn, In, Bi or Sb may be removed.Type: GrantFiled: February 4, 1988Date of Patent: August 29, 1989Assignee: DHV Raadgevend Ingenieursbureau BVInventor: Cornelis W.

Patent number: 4631624Abstract: A time delay undervoltage release for an electric circuit breaker causes the circuit breaker to trip when the control voltage drops below an acceptable level and prevents the breaker from being closed until the control voltage rises to a predetermined level. When the control voltage drops below an acceptable level, the undervoltage release energizes a trip solenoid to trip the breaker. A variable delay is interposed between the control voltage dropping below the acceptable level and the trip solenoid being energized. At the same time the trip solenoid is energized, an inhibit solenoid is deenergized to block the operation of the push-to-close button. When the control voltage increases to a predetermined level, the inhibit solenoid is energized, allowing the push-to-close button to be manually operated and the breaker returned to service.Type: GrantFiled: November 2, 1984Date of Patent: December 23, 1986Assignee: Square D CompanyInventors: Robert F. Dvorak, Harley W. Jansen, Henry J. Zylstra
