Abstract: Apparatus is provided for automatically carbonating a liquid. A pressure vessel receives carbonating gas at a pressure P.sub.1 via a first input, and a supply of liquid at a pressure P.sub.2 via a second input. P.sub.2 is greater than P.sub.1. The flow of liquid into the pressure vessel is restricted, to enable carbonating gas to enter the vessel and substantially reach the pressure P.sub.1 therewithin before liquid entering the vessel raises the interior pressure above P.sub.1. An output is provided for drawing carbonated liquid out of the pressure vessel. The apparatus is particularly suitable for residential use in providing Seltzer water, where it operates at conventional municipal or private well water pressures.

Abstract: An apparatus for the carbonation of liquids, such as water, comprises a liquid storage tank coupled to a carbonizer having a carbonated liquid holding tank which presents a carbon dioxide atmosphere to liquid introduced therein. The liquid introduced into the holding tank blends with the carbon dioxide atmosphere, and is held in the tank for withdrawal upon demand. The liquid storage tank maintains a liquid therein at ambient pressure, and has a draw tube for liquid removal positioned proximate the bottom wall of the tank. The tank has a channel system in the tank bottom to allow liquid to collect therein to maximize the amount of liquid which may be withdrawn. Liquid level switches sense the level of liquid within the channel system and are coupled to the carbonizer to prevent its operation when insufficient liquid is present in the storage tank.
Abstract: The present invention represents an improvement in state of the art apparatus for injecting controlled amounts of a soil amendment, including fertilizers, into an irrigation system, by first effecting the batch mixing of a selected soil amendment, in the form of a particulate material in a fluid medium, such that the particulate material is either dissolved or suspended in the fluid medium to form a slurry, continuously locating an area within the mixing tank in which the admixture displays the greatest, or optimum homogeneity, and continuously withdrawing metered amounts of the resultant slurry for injection into an irrigation system over the entire period of the irrigation cycle.
Abstract: A coffee grinder which has several different automatic grinding capacities is connected to a coffee brewer which has several different automatic brewing capacities by a control that inhibits brewing of all but the corresponding brew capacity following grinding of a quantity of coffee. The grinder is also inhibited from grinding any more coffee until the appropriate brew cycle of the coffee brewer is started. Once the corresponding brewing cycle is selected, the coffee grinder is reset and any grinding capacity may be selected. A calibration mode for the coffee grinder and the coffee brewer is provided wherein the duration of the grinding cycle or brewing cycle, respectively, is set by manually initiating the cycle and then halting of the cycle when the appropriate capacity is reached. The duration of the cycle is then set for subsequent automatic operation.

Abstract: An automatic breadmaking appliance has an outer housing containing a baking chamber for receiving a mold in which the bread ingredients are mixed, kneaded and baked. A heating element located in the baking chamber supplies heat as necessary throughout the breadmaking process and an improved ventilating system is selectively operable under control of the appliance process controller to circulate cooling air through the baking chamber and to recirculate heated air from the upper region of the baking chamber to the lower regions thereof to accelerate heating and conserve energy. The ventilating system also effectively cools the housing and prevents condensation from forming thereon. Temperature sensing means located outside the baking chamber senses the temperature of the contents of the mold in the baking chamber. An improved viewing window, window cover, and light facilitate visual inspection of the bread being baked.
Abstract: The appliance, in particular a coffee machine, comprises three boilers (1, 2, 3). In addition a heating element (10, 11, 12) is disposed in each boiler, which element can be switched on and off through one switching means each (20, 21, 22) which are provided in a control mechanism (16). In each of the boilers moreover there is one temperature sensor (13, 14, 15) to measure the temperature of the hot water. The control mechanism (16) has in addition computational means (17) as well as memory means (18, 19). Among other things predetermined desired temperatures for the water in the individual boilers as well as the maximum available power supply of the coffee machine can be stored in the memory means (18, 19). The control mechanism is designed in such a way that, based on the water heating pattern in the individual boilers, the heating capacity can be apportioned to the boiler which needs it most according to a certain order of priority.
Abstract: An orbital shaking attachment can be fitted or removed from a magnetic stirrer thereby giving the stirrer the extra function of orbital shaking in addition to its primary function of magnetic stirring. The principal of he invention could also be used to make a dedicated orbital shaker for other applications such as in an over, incubator or liquid filled tank. The orbital shaking attachment includes a top-plate/platform with a circular magnet attached centrally to its underside and a base-plate with a central circular hole. The two plates are separated by ball bearings which are able to roll around orbitally in bearing cups on both plates. When operated the base-plate is static and the top-plate/platform moves orbitally. The device is constructed mainly from nonferrous material except for the circular magnet and ball bearings.
Abstract: A semiconductor processor blending system for diluting a concentrated liquid additive into an actively flowing primary liquid. The concentrated additive is stored in a reservoir and transferred to a drained mixing tank via a metering pump. A diluent supply adds a measured amount of diluent to the mixing tank to provide a diluted additive. Primary fluid flows through aspirator-injectors having a suction port which draws from the mixing tank. This provides two-stage dilution which can easily achieve very dilute ratios of the additive.

Abstract: In known beverage dealcoholizing plants, one disadvantage is that volatile content materials always escape, and the end product consequently lacks aroma materials and/or preserving materials that were previously present. This disadvantage is eliminated in that the volatile content materials, previously lost into the surroundings via the vacuum pump, are fed back again into the beverage. A duct at the exhaust air pipe, connected to the vacuum pump and leading to a gas washer, circulates the volatile content materials back into the beverage.
Abstract: A coffee-making machine includes a reservoir connected to an external water supply via a valve which is divided into hot and cold water tanks. The cold water tank feeds a boiler which operates to heat the water in the cold water tank only when a brew cycle has been initiated. Heated water from the boiler is fed to an expansion chamber before being discharged onto the ground coffee via a spray head at the end of the expansion chamber. Upper and lower water level sensors are in the cold water tank and detect water level conditions therein. A controller communicates with the upper and lower level sensors and the boiler and allows a brew cycle to be initiated only when the water level in the cold water tank is detected by the upper level sensor. When the water level in the cold water tank falls below the lower level sensor, the controller disables the boiler and opens the valve to replenish the water level in the cold water tank.
