  • Patent number: 5126534
    Abstract: A toaster having double-wall construction controls the flow of air within its interior so that its exterior is kept cool. Air intake occurs near the edge of the top toaster slot where bread or the like is inserted for toasting. Intake air then travels down the immediate interior of the toaster and is introduced to the toasting chamber and an associated warm air flow channel near the bottom of the toaster. Air warmed by the toasting chamber and associated channel rises and pulls cooler air from below. The warm exhaust air is channelled away from the cool intake air by means of a top cover.

    Abstract: Apparatus for warming a sterile liquid includes a basin with a heater assembly, a base surrounding the basin, and an electronic temperature controller. The shape of the basin bottom includes an plateau-like elevated central region and a depressed surrounding rim. The heater assembly is of a thin-film type, and provides relatively greater heating in the central region than in the outer region. Both the heater geometry and the shape of the basin bottom promote a natural and uniform convective flow of the liquid to promote mixing of the warmer and cooler portions of the liquid. The temperature controller allows the user to select the temperature that the liquid is to be warmed to, and provides visual and aural indications of liquid or basin temperatures which exceed reasonable pre-set limits. The controller also halts the flow of electrical current to the heater assembly when an overtemperature problem in the liquid or the basin is detected. A disposable cable connects the temperature controller to the basin.

  • Patent number: 4922082
    Abstract: An ohmically or electrothermally controlled valve gate for injection molding apparatus comprises three concentrically located tubes in intimate contact with each other. The innermost tube is an electrode and also serves as the passage for flowing molding material. The outermost of the three tubes is also an electrode. The intermediate tube is a resistive heating element comprising a mixture of at least two highly compacted powders. One powder is an electrical conductor, while the other powder, which serves as a binder for the first powder, is an electrical insulator but a good thermal conductor. Current flow between the electrodes occurs at points of contact between adjacent particles of the conductive powder. Thus, the electrical resistance and therefore the generation of heat is controlled by the composition and quantity of binder in the heating element. The generated heat is conducted through the inner electrode tube to the flowing plastic to melt the plastic and "open" the gate.

  • Patent number: 4901631
    Abstract: A toaster for heating both a frankfurter and a frankfurter bun is disclosed. The toaster has a frankfurter heating chamber having associated first heating elements for heating at least two opposed surfaces of a frankfurter placed in said frankfurter heating chamber and at least one bun heating chamber having an associated second heating element for heating at least one surface of a bun placed in said bun heating chamber. The toaster includes an elevator having a first portion for supporting the frankfurter in the frankfurter heating chamber and a second portion for supporting the bun in the bun heating chamber. A connecting means connects the first portion to said second portion and permits a limited amount of play between said first and second portion. In one embodiment the connecting means includes a generally upside down U-shaped link bar.

  • Patent number: 4888463
    Abstract: An apparatus for maintaining thermal control of the temperature of a microscope stage is provided. A thin copper plate is arranged with a non-inductive serpentine heating element pattern controlled by a proportional power controller. A thermistor temperature sensing device is arranged to sense the temperature near the specimen container and to provide the sensed data to the controller. Proportional power control is accomplished by varying the ratio of "ON" and "OFF" power cycles as the desired temperature is approached.

  • Patent number: 4873424
    Abstract: An appliance for electrically heated disinfection of contact lenses or similar ojects is provided with a molded plastic housing having a recessed cavity for insertion of a conventional side-by-side horizontal lens storage case containing the lenses immersed in disinfecting liquid, typically saline solution. The cavity has horizontally aligned opposite end openings through the sides of the housing and the openings are located and dimensioned to allow unobstructed sliding passage of the lens case from the cavity so that the lens case will fall by gravitation from the cavity through one of the openings when the housing is rotated 90.degree. to vertically align the openings. The cavity openings thus ensure that the lens case cannot be heated in the appliance in a vertical orientation which could damage the lenses by heated exposure above the level of the disinfecting liquid.

  • Patent number: 4822981
    Abstract: A self-regulating warmer device which is especially suited for the food service industry. Such devices are suitable, for example, for keeping wrapped or unwrapped food products at a desired holding temperature between the time the food is prepared and the time it is delivered to the customer. The warmer device includes a plate on which the food is held and a self-regulating warmer element beneath the plate to keep the plate at a uniform temperature. The plate is preferably used with spaced apart infra-red convection heaters such as those commonly used in fast food restaurants, and provides even food heating regardless of the changes in ambient conditions, the number of food products located between the infrared heater and the plate and provides dramatic reductions in power usage. Moreover, heat losses which occur at the edges of the plates now used for these applications are reduced and localized hot or cold spots are eliminated.
