  • Microwaveable coffee makers
    Patent number: 5010221
    Abstract: A drip-type coffee maker adapted for use in a microwave oven. The coffee maker includes a container which can dispense coffee directly into a receptacle therebelow and has an upper reservoir for holding water, a lower filter element for holding coffee grounds and a partition, which separates the reservoir and coffee filter element. The partition includes a portion thereof adapted to close and open communication between the reservoir and the filter element, and a non-toxic heat responsive sealing substance adapted to releasably seal the partition portion in the closed position until water in the reservoir reaches a temperature for brewing coffee.

  • Vacuum drier apparatus
    Patent number: 5007183
    Abstract: A vacuum drier apparatus capable of preventing the thermal deformation of the protection member as well as scattering of the tempered glass plate in a case of an accidental breaking of the tempered glass plate. The apparatus includes elastic supporter members located between the glass plate and the protection member, for supporting the glass plate and the protection member with respect to each other, such that the glass plate can be pressed tightly to seal off the opening section of the vacuum drying space, while the protection member can be pushed away from an edge of the front side of the opening window by an external pressure exerting on the protection member. The protection member is preferably a transparent plastic plate in an outwardly curving dome-shaped form.

  • Apparatus for production of synthesis gas using convective reforming
    Patent number: 5006131
    Abstract: A convective reformer device is provided which is useful for partially reforming a feed mixture of hydrocarbons and steam. The device includes an outer shell enclosure and a tubular inner core assembly and is specifically adapted to support heat exchange between a heating fluid, which may be an effluent from downstream, and the hydrocarbon-steam feed mixture. The convective reformer is used in a system and process for the steam reformation of hydrocarbons, in which the partially reformed effluent from the convective reformer is further reformed in a steam reforming furnace, or an auto-thermal reformer, or a steam reforming furnace followed by an auto-thermal reformer. The fully reformed effluent from the steam reformer, or auto-thermal reformer, is directed back to the convective reformer to supply the heat of reaction for the partial reformation of the feed mixture.

  • High-productivity bobbin winding method and devices for its implementation
    Patent number: 5004171
    Abstract: A high-productivity bobbin winding method comprising a variable-duration intervention cycle for restoring yarn continuity. The cycle is divided into two parts, of which a first part is devoted to braking the bobbin and a second part is devoted to joining the yarn, between the commencement of the two parts there being interposed a delay which varies as a function of the time measured for the bobbin to come to rest during the preceding intervention cycle.

  • Method of processing a food product having a liquid content
    Patent number: 5004621
    Abstract: A method and a relevant facility for the treatment of an alimentary product with a liquid content calls for a step in which this whole alimentary product is disintegrated and in which the disintegrated alimentary product is for the first time at such a temperature as to undergo an evaporation, and calls for subsequent steps of processing of the disintegrated alimentary product; the evaporate resulting from the evaporation is condensed and collected, with the flavoring substances contained in the evaporate being recovered.

  • Prosthetic heart valve
    Patent number: 5002567
    Abstract: In a prosthetic heart valve comprising a generally annular stent and at least two obturators mounted in the stent so as to be above to pivot between an open position and a closed position, the stent is provided with at least one element which projects inwardly of the stent itself, while each of the obturators has recesses which cooperate with the projecting element of the stent with clearance in a generally-hinged configuration which enables the obturators to pivot between the open position and the closed position.

  • Controlled sampler
    Patent number: 5000052
    Abstract: The present invention is concerned with a controlled sampler device which draws a gas through a contaminant collection device. The controlled sampler comprises an inlet to the sampler; a pump adapted to draw a gas through the inlet; a reference element that provides a reference signal; a feedback element with an output; a differential pressure transducer to compare the reference signal with the feedback signal to provide an error signal that is linearly related to selected and measured values; an integrator with an input connected to the output of the differential pressure transducer and to a summer; and means between the differential pressure transducer and the summer to provide a signal to the summer which is proportional to the error signal, which is passed to a driver which regulates the speed of an electric motor to change the flow rate to reduce the error signal to a null.
