Patent number: 7866679Abstract: The trash can cart apparatus provides a frame which selectively encloses two separate trash cans, allowing a user to use different sizes of trash cans, selectively. Each individually pivoted keeper is u-shaped and selectively covers each can. Each keeper further comprises a screen to prevent access to trash can lids, especially by animals, each keeper positionably lockable, and requiring the latch mechanism to be manually released prior to pivot. Each can if fully secured by frame and keepers only. The multiple lower laterals provide that any can is supported by at least two laterals. The apparatus needs only two wheels. The wheels are positioned at the lower front and the pivoting handle at the upper front. A user need only grasp the handle to pivot the mass of the apparatus, along with any trash cans.Type: GrantFiled: October 21, 2008Date of Patent: January 11, 2011Inventor: Daniel F. Leon

Patent number: 7047612Abstract: This invention relates generally to a method for repairing a casting, and more specifically to a method of repairing a casting by pouring melted filler material into a damaged portion of the original casting. Damaged cast metal components, such as a cylinder head of an internal combustion engine are repaired by preheating the component to a first preheat temperature. The damaged area of the casting is then heated to a higher temperature using a torch and melted filler material is poured into the casting. The torch is used to maintain the temperature of the melted material for thirty seconds to two minutes. The temperature of the filler material is then cooled using compressed air.Type: GrantFiled: May 2, 2003Date of Patent: May 23, 2006Assignee: Caterpillar Inc.Inventors: Michael D. Bridges, Leonid Chuzhoy, Christopher A Kinney, Jose F. Leon Torres, Stephen E Post, Robert E. Sharp

Publication number: 20060021070Abstract: Novel cultured inner cell mass (CICM) cells, and cell lines, derived from ungulates, in particular, pigs and cows, and methods for their preparation are provided. The subject CICMs possess similar morphology and express cell markers identically or substantially similarly to ICMs of undifferentiated developing embryos for prolonged culturing periods. Heterologous DNA is inserted into the subject CICM cells and cell lines so as produce transgenic CICM cell which are introduced into non-human fertilized embryos to produce transgenic chimeric embryos. The transgenic chimeric embryos are transferred into recipient females where they are permitted to develop into transgenic chimeric fetuses. Recipient females give birth to transgenic chimeric animals which are capable of transmitting the heterologous DNA to their progeny. Transgenic CICM cells are also used to produce cloned transgenic embryos, fetuses and offspring.Type: ApplicationFiled: December 28, 2004Publication date: January 26, 2006Applicant: University of Massachusetts, A public Institution of Higher Education of the Commonwealth of MAInventors: Steven Stice, Jose Cibelli, James Robl, Paul Golueke, F.

Patent number: 5403252Abstract: A climbing exercise apparatus is provided having a frame on which two pedals are pivotally mounted to provide a user with a vertically reciprocating exercise movement, and a control panel for user input and output. A dynamic break, alternator or the like applies a variable level of resistance (via a suitable transmission) against the user's movement. The resistance varies over time in accordance with a control signal generated by a computer. The value of the control signal is independent of the rate at which the user steps. A display successively displays images of hills. Each hill is associated with one of the series of values, and that value is graphically represented as part of or in visual association with the hill image.Type: GrantFiled: November 3, 1992Date of Patent: April 4, 1995Assignee: Life FitnessInventors: Tomas F.

Patent number: 5335760Abstract: A solenoid for controlling the engagement and disengagement of a wrap spring clutch includes an electromagnetic coil having a core member disposed adjacent one axial end thereof. An armature is provided within the electromagnetic coil for selective axial movement in response to the energization and deenergization of the electromagnetic coil. The armature is connected to an actuator for the wrap spring clutch such that movement of the armature controls the engagement and disengagement thereof. The core member and the armature are both formed from relatively soft, magnetically permeable materials. A flux breaker is disposed within the electromagnetic coil between one axial end of the armature and the core member. The flux breaker is formed from a relatively hard, non-magnetically permeable material, such as stainless steel. The flux breaker prevents the armature from contacting the core member when attracted thereto by energization of the electromagnetic coil.Type: GrantFiled: August 5, 1993Date of Patent: August 9, 1994Assignee: Dana CorporationInventor: Michael F.
