  • Patent number: 6513570
    Abstract: 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.

  • Patent number: 6513574
    Abstract: Device in connection with a water-cooling system for direct chill semi-continuous casting equipment for casting metal, in particular casting aluminium ingots (14). The solution comprises one or more chills (9) arranged in a frame structure with an integral water distribution box (18). The chill(s) comprise(s) a mould chamber surrounded by permeable wall elements (10) for the supply of oil and/or gas and is(are) open at the top with an opening (13) for the supply of molten metal and, at the start of each casting operation, is(are) closed at the bottom by means of a mobile support. The metal is cooled in two stages, by primary cooling in the mould chamber and secondary cooling by direct water cooling immediately below the primary cooling area. A separate cooling circuit called the recooling circuit is arranged to cool the chills after the end of the casting cycle. The recooling (1, 2, 3) and secondary cooling (11, 19) thus consist of two separate cooling circuits.

  • Patent number: 6513576
    Abstract: The invention provides an air-liquid heat exchanger for a motor vehicle fluid-flow circuit (2, 3), the heat exchanger comprising a plurality of tubes (4) extending between two fixing and distribution blocks (5, 6) to which the ends of the tubes are coupled, each of said two blocks comprising: a face (10, 13) facing the other block and carrying internal coupling members (15) for coupling the corresponding ends of the tubes (4) to the block in question; an internal distribution channel (17) interconnecting the internal coupling members (15); and an external coupling member (19) for coupling the block in question and its internal distribution channel (17) to the fluid-flow circuit (2, 3) of the vehicle. At least one (5) of the two blocks has at least one ventilation nozzle (23) passing therethrough between its face (10) carrying the internal coupling members (15) for coupling tubes (5) to said block, and its opposite face (9).

  • Patent number: 6513578
    Abstract: 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.

  • Patent number: 6513579
    Abstract: 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.

  • Patent number: 6513580
    Abstract: 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.

  • Patent number: 6513581
    Abstract: 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.

  • Patent number: 6513583
    Abstract: 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.
