Patent number: 6513570Abstract: An apparatus and method for pressure casting a battery part wherein the state of molten lead is monitored so that when the molten lead enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears.Type: GrantFiled: September 17, 2001Date of Patent: February 4, 2003Assignee: Water Gremlin CompanyInventor: Robert W.

Patent number: 6513578Abstract: A method of operating a frozen beverage machine is disclosed that utilizes a short “burst” heating of the beverage machine's freezing chamber. The method includes monitoring a beverage mixture within the freezing chamber of the frozen beverage machine, and heating the freezing chamber for a predetermined time period in response to the beverage mixture reaching a first predetermined state. The freezing chamber is then refrigerated until the beverage mixture reaches a second predetermined state.Type: GrantFiled: July 18, 2001Date of Patent: February 4, 2003Inventor: Jimmy I. Frank

Patent number: 6513579Abstract: An automotive condenser includes closely nested, plastic molded support brackets solidly tightly fitted to the four corners thereof, post braze and with no separate fasteners, which adhere to the corners solidly enough to prevent any significant twisting or shifting relative thereto. A reinforced support flange on the bracket is stiff enough to prevent any significant twisting relative to the bracket itself, when subjected to the level of torque to be expected when an inlet or outlet pipe of the condenser is installed to a refrigerant line. Therefore, the support flange of the bracket can hold the end of the pipe solidly enough to allow the refrigerant line to be connected thereto with no need for a back up tool or other external support to resist the torque.Type: GrantFiled: September 27, 2001Date of Patent: February 4, 2003Assignee: Delphi Technologies, Inc.Inventors: Scott Edward Kent, David A. Southwick

Patent number: 6513580Abstract: A heat exchanger for using a hot liquid to warm a cold substance that is fluid and foamy, containing solid particles and gas, such as liquid manure. The invention is characterized in that it comprises a plurality of unit heat exchangers (1) connected in series, each constituted by a horizontal tube (2) having a heat conducting wall, in which the substance is caused to circulate from one end to the other, and a concentric tubular case (3) surrounding said tube (2) in which the hot liquid is caused to circulate from one end to the other in the opposite direction to the circulation of said substance, and that inside said tube (2) there is coaxially mounted a rotary shaft (4) carrying a helical brush (40) forming an Archimedes' screw thread that rubs against the inside wall of the tube (2) to ensure that the substance is transported therealong. Said heat exchanger is particularly useful for preheating liquid manure in a dehydration installation.Type: GrantFiled: July 13, 2001Date of Patent: February 4, 2003Assignee: SirvenInventor: Jacques Bourdel

Patent number: 6513581Abstract: The invention relates to a process for the production of a heat transfer device, which comprises electroless chemical deposition of a metal/polymer dispersion layer, in which the polymer is halogenated, on a heat transfer surface. The invention furthermore relates to a process for the production of a heat transfer device, wherein a metal/phosphorus layer with a thickness of from 1 to 15 &mgr;m is applied by electroless chemical deposition before application of the metal/polymer dispersion layer. The invention furthermore relates to a heat transfer device which can be produced by a process according to the invention, and to the use of a coating, produced by electroless chemical deposition of a metal/polymer dispersion layer, in which the polymer is halogenated, for reducing the tendency of the coated surfaces to accumulate solids from fluids, causing fouling.Type: GrantFiled: June 26, 2001Date of Patent: February 4, 2003Assignee: BASF AktiengesellschaftInventors: Stephan Hüffer, Axel Franke, Stephan Scholl, Hans Mueller-Steinhagen, Qi Zhao, Bernd Diebold, Peter Dillmann

Patent number: 6513583Abstract: A heat exchanger has a shell formed of several sections placed side by side and each defining an intermediate baffle forming part of a spiral surface. The adjacent sections define together a spiral path extending through the shell in the direction of its axis. Tubes extend in this axial direction through aligned holes provided in each shell section. The tubes communicate between end spaces comprising an inlet and outlet for the first fluid. The use of shell sections provides a convenient construction method for the heat exchanger while the spiral path for the second fluid gives better flow characteristics.Type: GrantFiled: April 23, 2001Date of Patent: February 4, 2003Assignee: Serck Aviation LimitedInventor: Steve John Hughes

Patent number: 6513584Abstract: A plate heat exchanger including adjoining plates disposed adjacent one another and having peripheral grooves and channels alternately for media giving off heat and absorbing heat, seals made of an elastic material each being emplaced between the adjoining plates in the groove of one of the plates, attachment holes in each plate, and nipples on each seal insertable in the holes and with cross-sections different from the penetration cross-sections of the holes such that the nipples when inserted into the holes are not compressed about their entire circumference but only at spaced sites thereon at which the nipples project beyond the margin of the holes. The holes are defined by downturned edges which have radii and point in the insertion direction of the nipples into the holes.Type: GrantFiled: July 23, 2001Date of Patent: February 4, 2003Assignee: GEA Ecoflex GmbHInventors: Reinhard Lehmann, Uwe Hachmeister
