  • Patent number: 5897203
    Abstract: A dough portioning and kneading machine comprises two dough hoppers separated from each other, a conveying chamber, in which a conveying piston is displaceably arranged, being disposed downstream of each dough hopper. At least one metering chamber is disposed downstream of each conveying chamber and is movable between a first position open towards the conveying chamber and a second position free from the conveying chamber. A metering piston is displaceably disposed in each metering chamber and partially releases the metering chamber in the latter's first position and empties the metering chamber in the latter's second position.

  • Patent number: 5713263
    Abstract: An improved apparatus for aerating wine. The apparatus includes a housing for containing wine and air, a baffle positioned within the housing interior, and a valve which permits the placement of the wine into the housing interior. The housing can be inverted to mix the wine and air, and the valve prevents the leakage of wine from the housing interior. In one embodiment of the invention, an aperture such as a spout can be attached to the housing to permit the removal of the wine from the housing interior, and the valve is selectively openable to prevent a vacuum as the wine is poured from the apparatus. In another embodiment of the invention, the baffle can be positioned to faciliate the valve closing when the housing is inverted to position the valve on the lower end of the housing.

  • Patent number: 5709466
    Abstract: An improved mixer for cementitious materials is described. This mixer is mobile and carried to the desired site and comprises a series of tanks and bins for containing the material to be mixed. The device is particularly useful in mixing hazardous wastes (e.g. low level radioactive soils, for example) within cementitious material along with sealants and chemicals designed to encapsulate the hazardous wastes therein. In order to thoroughly mix, and thus contain the hazardous wastes, the residence time within the mixing means must be between 4 and 45 seconds. This residence time may be achieved by keeping the mixing means within certain parameters of angles, relative to the ground, speed of mixing and length of mixing. By carefully controlling these variables, it is possible not only to achieve thorough mixing and encapsulation of the hazardous waste and to make a mobile mixing device that is extremely useful within the metes and bounds of the invention.

  • Patent number: 5669287
    Abstract: A method and system for brewing a desired volume of coffee at a selected brew time, in which a volume of water corresponding to the desired volume of coffee is heated and directed into contact with coffee grounds in a brewing chamber. Contact between at least a portion of the heated water and the coffee grounds is maintained for approximately the selected brew time to form brewed coffee. The brewing time, however, is substantially independent of the desired volume of coffee to be brewed and is controlled by control of the rate at which heated liquid flows into or out of the brewing chamber. At the expiration of the brewing time, brewed coffee is released through an opening in the brewing chamber and into an underlying receptacle.

  • Patent number: 5651613
    Abstract: A 55 gallon drum is provided with a static mixer that enables internal mixing of product during barrel rotation. Before fastening of at least one of the respective lids, a circular elastic ring insert is place within the barrel. This circular plastic ring insert has a diameter exceeding that of the barrel, has two external protuberances for keying to the cylindrical inside of the barrel at internal ribs, and is cut across the ring so as to interrupt the otherwise endless dimension of the ring. Upon insertion to the barrel, the ring is opened at the cut and disposed in an auger like helix along the inside cylindrical wall of the drum. The two protuberances are keyed to the drum interior of the internal ribs to effectively fasten by friction its helical auger like path on the cylindrical inside wall of the drum. Thereafter, the drum is closed and filled with product. Upon drum rotation, relative motion between the contained product and helical auger like static mixer occurs.

  • Patent number: 5644972
    Abstract: The present invention comprises a system for brewing and dispensing high quality beverages at remote locations comprising a high volume urn, a high volume transfer system, an insulated mobile canister, a dispensing system having a compressor, tank and hose assembly, and a dispensing tap. Coffee, or other brewed beverage, is brewed in the high volume urn. Once a complete batch of coffee has been brewed, the entire batch is transferred via gravity to a clean and empty mobile canister. Once full, the mobile canister can be moved to a remote dispensing location or stored for future use. When the mobile canister is moved to the dispensing location it is connected to the dispensing system which uses an air compressor to pressurize the beverage within mobile canister. The dispensing system also connects the canister to the dispensing tap, via a short, removable dispensing hose.
