Heating Or Cooling Element In Platen Patents (Class 100/325)
  • Patent number: 8833243
    Abstract: A grill includes a lower platen assembly having a lower grilling surface and a pivotally attached upper platen assembly having an upper grilling surface. The upper platen assembly includes three motors encased in a shell. A cable attached to each motor suspends the upper grilling surface. The grill is automatically calibrated to ensure that the upper grilling surface is level. Each motor independently and sequentially raises the upper grilling surface from the lower grilling surface. When the upper grilling surface lifts from the lower grilling surface, the current in the motor changes. The settings of each motor at this instant are stored in a control to determine the calibration point when the upper grilling surface is level. The grill also automatically recognizes a food item placed on the lower grilling surface to determine the cooking parameters of the grill.

  • Patent number: 7601930
    Abstract: Compression-resistant heating frame, comprising an upper plate and a lower plate which are secured to each other, and a heating layer interposed between the two plates. Force-absorption studs are disposed between the two plates in order to protect the heating layer against deformation by compression of the plates against each other. The studs are distributed to permit regular heating of each plate. The force-absorption studs are distributed at the nodes of a rectangular, hexagonal or centered square network. The force-absorption studs preferably include a flange to distribute the compression force on a metal base sheet which is interposed between the upper plate and the heating means. Thermal insulation material is interposed between the heating layer and the upper plate. The heating layer may comprise a film through which an electric circuit passes in order to produce heating by joule effect.

  • Publication number: 20080216677
    Abstract: An ice-carving machine comprises a framework, an ice block positioning system, at least one feeding system, and at least one heating mold. The ice block positioning system is fixed on the workbench of the framework for positioning the ice block to be processed. The feeding system drives the heating mold to heat and press the ice block in a mold cavity with a predetermined shape. By the pressure and heat of the heating mold, the ice block is made into the shape identical to the shape of the mold cavity, thus simplifying the process of carving ice blocks, and also saving carving time and cost, being especially suitable for a mass production of ice sculptures.

  • Patent number: 6598520
    Abstract: In a hot pressing apparatus, a hot-plate pressing cylinder is provided at the center of a moving plate, and a substantially central part of each of the materials to be laminated between hot plates, which are pressed by a fixed plate and a moving plate, is pressed by a hot-plate pressing cylinder of the moving plate. Thus, a uniform pressure can be applied to the materials to be laminated, thereby preventing the occurrence of defects such as wrinkles and bubbles in the products.

  • Patent number: 6038785
    Abstract: A vacuum dryer panel for a leather drying machine wherein a dryer panel comprising a porous screen is mounted over a perforated plate on the underside of a vacuum chamber positioned above a heated drying table on which leather skins are dried. The dryer panel comprises a layer of fine mesh screen preferably formed of a synthetic resin material mounted on a porous backing preferably formed of a synthetic resin material. The backing material is adapted to be mounted adjacent an outer side of the perforated plate and provides porosity between the screen and adjacent openings of the perforated plate. The backing material is sufficiently rigid to prevent the screen material from being pulled into openings in the perforated plate by a negative pressure on the upper side of the plate, so as to prevent marks in the dried leather. The edges of the dryer panel are folded over and incorporate reinforcing strips. Threaded fasteners fit through spaced openings in the edges for mounting the dryer panel to a vacuum chamber.

  • Patent number: 5989471
    Abstract: A BGA mould assembly which can facilitate high degree of control over the clamping force on BGA substrates of varying thickness. An Independent drive is provided for each of the dual in-line cavity bars which clamp the BGA substrates. The drive mechanism is a wedge press which includes a servo motor, and a linear-conversion mechanism coupled to the servo motor to convert the rotation motion of the motor to a linear movement. An input wedge is coupled to the linear-conversion mechanism such that the input wedge moves correspondingly with the linear movement of the linear conversion mechanism. An output wedge is coupled to the cavity bar and positioned such that a horizontal movement by the input wedge causes the output wedge to move downwards. A roller cage is provided at the top and bottom of the input wedge to reduce friction.

  • Patent number: 5907995
    Abstract: A continuous, multiple-stage process for thermally treating the surface of friction linings by pressing them against heated units and cooled units. The total length of the transport and pressing phases of each stage taken together corresponds to the continuous production cycle of the linings. The scorching press for carrying out the process is made of modules, so that heated and cooled units may be easily exchanged for each other. A heat insulation reduces energy tosses and keeps constant the surface temperature of the heated units.

  • Patent number: 5743179
    Abstract: The present invention relates generally to a frameless high pressure press. The high pressure press includes first and second opposed plates that are at least partially surrounded by a wrapping structure. A lift device is positioned on one of the first and second plates at a location offset from the wrapping structure. The press also includes a linkage structure that transfers force generated by the lift device to the wrapping structure such that the wrapping structure forces the plates together. The linkage structure includes a tensioning member connected to the wrapping structure and generally transversely aligned with respect to the plates. The linkage structure also includes a cross member that extends between the lift device and the tensioning mechanism. The length of the tensioning member can be adjusted to control the level of force multiplication generated by the press.

  • Patent number: 5634398
    Abstract: A multiple opening panel press is described with a plurality of movable platens which are individually controlled to adjust the spacing between adjacent platens to a predetermined panel width. Position-sensor transducers are employed to produce control signals corresponding to the platen positions which operate control cylinders by associated valves to adjust the platen spacing. The transducers are preferably sonic waveguides which interact with permanent magnets fixed to the movable platens to generate platen position signals which are applied to an automatic control system which includes a computer that produces the control signals.

  • Patent number: 5611269
    Abstract: A fluted or honeycombed profile on the rear side of the pressing stock or rolling side of the heating/press platens, which profile enables an increased flexible, two-dimensional deformation, in a longitudinally and transversely controlled manner, in just a few seconds in the on-line control process while providing larger support spacings. The fluted profile along the whole of the pressing zone advantageously increases the elastic bending deformability in the transverse direction, while, as a result of the honeycombed profile, an increased flexibility longitudinally to the pressing zone is attained. As a result of the fluted profile longitudinally to the pressing zone, the two-dimensional, spherical flexibility of the press/heating platen is substantially increased, so that use is preferably made of this fluted profiling.
