Abstract: Pressure regulators for beverage dispensers of the type using a high pressure gas cartridge such a CO2 cartridge. The regulators provide a simple, low cost, easily assembled and reliable regulator of particularly small size, facilitated in part by the fact that the invention allows the use of a diaphragm of a particularly small size without necessitating the use of expensive and bulky diaphragm clamps, such as threaded clamps, yet is able to provide a more than adequate seal at both the inner and outer portions of the diaphragm.

Abstract: A control valve has an inlet, a first outlet and a second outlet. The control valve includes a poppet valve to selectably close one of the first outlet and the second outlet. A pair of diaphragms move from a first position to a second position when fluid is supplied to the control valve to permit the poppet valve to close the first passage when fluid is removed from the control valve. A magnet operably couples a wireless transmitter to a power source when fluid is supplied to the control valve. The wireless transmitter may send a signal to terminate irrigation by the control valve when the control valve is one of a plurality of control valves connected serially to a master valve only by a fluid supply line.

Abstract: Carbonated beverage delivery tubes and methods for fabrication having a unitary molded structure to define a smooth beverage intake of decreasing area to a smaller diameter flexible plastic tube, and at the other end of the small diameter plastic tube, a smooth transition through an outward flaring region to decrease the velocity of the beverage without initiating foaming within the carbonated beverage delivery.

Abstract: Digital regulators using a plurality of latching solenoid actuators, each having a spring return, the springs being configured to provide a force on the valve member of a regulator, when the solenoid actuators are unlatched, in a binary progression. The solenoid actuators are selectively latched by an latching current pulse and retained in the latched condition by residual magnetism in a zero air gap magnetic circuit. Various embodiments are disclosed, including embodiments having the solenoid actuators side by side and in a stacked relationship, solenoid actuators having springs providing a spring force in a binary progression, solenoid actuators having equal springs and distributed in a binary progression from a hinge axis, and solenoid actuators not distributed in a binary progression from a hinge axis and not distributed in a binary progression from the hinge axis. Embodiments are also disclosed having the capability of interpolating between binary settings of the digital regulator.

Abstract: A device for controlling a temperature of a fluid includes a plurality of valve assemblies, each coupled to a cold fluid supply, a hot fluid supply, and an outlet line. An orifice is coupled to each outlet line and to a combined outlet line that is common to all orifices. Each of the orifices has a proportionally different flow area. Hot and cold fluid supply temperature sensing elements are coupled to supplies. A controller is coupled to the hot and cold fluid supply temperature sensing elements and the plurality of valve assemblies. The controller selectively couples one of the cold fluid supply or the hot fluid supply to the outlet line for each of the plurality of valve assemblies responsive to the cold fluid supply temperature sensing element, the hot fluid supply temperature sensing element, and a desired temperature in the combined outlet line.

Abstract: Herein disclosed is a combustion cell adapted for an internal combustion engine, comprising i) a hydraulic engine valve actuation portion capable of providing a selection of two different and stable engine valve lift (i.e., open) positions per engine valve or per coupled engine valves and ii) a fuel injection portion capable of providing a selection of comprising i) a hydraulic engine valve actuation portion capable of providing two stable engine valve lift positions and ii) a fuel injection portion capable of providing a selection of one, two or three injection pressure levels for injection fuel. The combustion cell provides more flexibility in control of incoming intake air, outgoing exhaust gas, and/or incoming injection fuel relative to an engine combustion chamber so as to better match engine operating conditions that may change over time.
