  • Patent number: 6427463
    Abstract: A method using controlled forced-convection to couple (or de-couple) a refrigerant-evaporator thermally to a refrigerated compartment, and a method to use heat from a fresh food compartment (or other compartment maintained above 0C) of a two or more temperature refrigeration appliance to defrost a freezer evaporator automatically without using a controller or heater. When thermally coupled to its compartment, an evaporator can provide efficient cooling to the compartment. The ability to de-couple the evaporator from its compartment enables refrigerant flow through the evaporator at significantly different temperatures than its compartment, but without significant heat transfer. This ability enables using a single refrigeration system (with one or no valves) to remove heat (sequentially) at two or more different temperatures from two or more refrigerated compartments.

    Abstract: The invention relates to a method for heating glass sheets to be tempered or heat-strengthened, in which method glass sheets are heated in a preheating furnace (1) by applying a hot-air blast and convection heating produced thereby to the opposite sides of a glass sheet and the preheated glass sheet is transferred from the preheating furnace (1) into a radiation heating furnace (2) for heating the glass sheet to a tempering temperature. During the convection heating of a glass sheet, the rotating speed of a hot-air fan (5) is increased while adjusting the heating effect of heating resistances (6) so as to maintain the temperature of blasted air substantially constant. Thus, the diminishing temperature difference between glass and air is compensated for by controlling the coefficient of heat transfer.

  • Patent number: 6427489
    Abstract: A process for producing a glass substrate for an information recording medium comprising: (a) providing a chemical reinforcement tank comprising a chemical reinforcement liquid contained therein, and a holding means for holding a glass substrate; and (b) chemically strengthening the glass substrate by immersing the glass substrate in the chemical reinforcement liquid, wherein ions are exchanged on the surface of the glass substrate with ions in the chemical reinforcement liquid having a diameter larger than that in the glass substrate; wherein at least one of a wall surface of the chemical reinforcement tank and the holding means is made from a stainless alloy which exhibits corrosion resistance in a high temperature region of the chemical reinforcement liquid, the stainless alloy being made from a martensitic stainless alloy or an austenitic stainless alloy. Such process prevents the adhesion of particles, such as fine iron particles onto the glass substrate.

  • Patent number: 6427492
    Abstract: A bushing including a terminal ear and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body which can include side plates, end plates, a bottom plate, and terminal ears coupled to the bushing body. Clamps are attached to the terminal ears to supply electrical current to the bushing to maintain the glass inside in a liquid state. Each terminal ear includes an upper portion and a lower portion. The upper portion is coupled to a side plate of the bushing. A clamp is attached to the lower portion of the terminal ear. The upper and lower portions are oriented at an angle with respect to each other. Support portions are provided along the side edges of the upper portions of the terminal ears. Support portions stiffen the terminal ear, thereby increasing its resistance to bending and fatigue stresses. Support portions do not contact the bushing and therefore do not directly conduct current to the bushing.
