Also integral to the RH housing portion 40. are bosses for attaching the snap action switches 80, which determine gate orientation and mounting a gear motor 90, and can generally be referenced as “gate position sensors”. Such switches could also be replaced with other gate position sensors such as know in the art such as hall effect switches, magnetic switches, optical devices, etc. The gear motor provides the driving torque to the gate 60 through a cam-coupling 70, which has four switch detents 71, oriented to an internal shaft indexing means.Type: ApplicationFiled: August 4, 2006Publication date: January 25, 2007Applicant: Mid-South Products Engineering, Inc.Inventors: Larry Unger, Mike Glavaris

Publication number: 20070017237Abstract: This invention describes a bypass valve, which allows a controlled, variable amount of Freon to continuously flow from the high pressure side of an air conditioning system to the low pressure side without passing through the compressor or radiator. Said valve is only fully closed when maximum cooling is desired. Said valve requires only a simple set-point thermostat and servo motor to automatically control automobile cabin temperature, while giving maximum savings of engine power and fuel economy.Type: ApplicationFiled: July 19, 2005Publication date: January 25, 2007Inventor: David Rieck

Publication number: 20070017239Abstract: A self-regulating cooling/heating system employs a variable flow manifold that allows the automatic re-direction of cooling/heating fluid (air, water, phase transition medium) to the areas of the cabinet or enclosure that requires the most cooling/heating. This enables a more efficient use of cooling/heating capability, sending the cooled/heated fluid to areas of greatest temperature differential, which will result in a greater amount of thermal energy being transferred to the cooling/heating medium. This technique yields more efficient electronics and systems.Type: ApplicationFiled: July 22, 2005Publication date: January 25, 2007Inventors: Robert Monson, John Abraham

Publication number: 20070017240Abstract: A refrigeration system includes a primary compressor that receives refrigerant from an evaporator and delivers refrigerant to a condenser, a subcooling compressor that delivers refrigerant to the condenser, and a subcooler that receives refrigerant from the condenser. A first refrigerant flow path and a second refrigerant flow path pass through the subcooler. The first refrigerant flow path delivers a portion of the refrigerant to the evaporator, and the second refrigerant flow path delivers a remainder of the refrigerant to the subcooling compressor. The refrigeration system includes a controller operable to control operation of the subcooling compressor such that the refrigeration system operates at a point of highest efficiency.Type: ApplicationFiled: July 19, 2005Publication date: January 25, 2007Applicant: Hussmann CorporationInventor: Doron Shapiro

Publication number: 20070017241Abstract: Improved means for powering and increasing evaporative cooling in an indirect-direct evaporative cooling (IDEC) apparatus are disclosed. Sustainable energy from solar energy mixed with grid power, when needed, power the IDEC device. These DC and AC power sources are seamlessly merged in a unique diode interconnect unit. Improved means for evaporative cooling include a rayon-based flocking on the wet side of molded plastic indirect evaporative cooling plates. Separate wet and dry passages through those plates are facilitated by a unique means for clamping the upper ends of the plates. These clamping means also add to the structural integrity of an array of plates so that the array can be inserted in and removed from a housing containing other operational components of the IDEC such as fan, direct cooling plates and water distribution means.Type: ApplicationFiled: September 27, 2006Publication date: January 25, 2007Applicant: Speakman CompanyInventors: Samuel Hyland, Robert Lobozo, Covington Stanwick

Publication number: 20070017242Abstract: The present invention relates to a system for heat refinement by utilizing waste heat in a conduct (6) comprising a first cycle (2), an evaporator (4) In which the circulating working fluid is evaporated to gas, a compressor (8) that compress the gas, a condenser (10) that condenses the gas to a condensate and releases heat to a passing heat carrier in the condenser, and an expansion valve (14) that expands the condensate and bring back the working fluid to the evaporator (4). The system further comprises a second cycle (16; 16a-d) is attached to the first cycle (2), a turbine (18), which supplies gas from the evaporator (4),,whereby an expansion occurs, whereafter condensate is brought back to the evaporator (4).Type: ApplicationFiled: September 9, 2004Publication date: January 25, 2007Inventor: Ake Johansson

Publication number: 20070017243Abstract: An coaxial-flow heat exchanging structure having a proximal end and a distal end for exchanging heat between a source of fluid at a first temperature and the environment (e.g. air, ground, water, slurry etc.) at a second temperature. The coaxial-flow heat transfer structure comprises: a thermally conductive outer tube section, and an inner tube section having an inner flow channel and being coaxially arranged within the outer tube section. An outer flow channel is formed between the inner and outer tube sections, and helically-extending turbulence generator is provided along the outer flow channel, so as to create turbulence along the flow of heat exchanging fluid flowing between the inner and outer flow channels, and thereby increasing the heat transfer through the walls of the outer tube section to the ambient environment.Type: ApplicationFiled: April 28, 2006Publication date: January 25, 2007Inventors: John Kidwell, Michael Fraim

Publication number: 20070017244Abstract: The compressor head, internal and/or external discriminator, and manifold design in general utilize ball valves on the suction and discharge of a cylinder head in the recovery of refrigerant liquid and/or vapor. The device facilitates the flashing of liquid refrigerant pumped to the compressor which, in turn, assists to cool the compressor head. The flashing of liquid refrigerant to vapor also deters liquid transfer into the compressor enhancing performance thereof. The vapor passages within the discriminator, cylinder head and/or manifold are sized for receipt of spring actuated ball's to open and/or close the vapor passages during suction and/or discharge of refrigerant vapor or liquid by the compressor.Type: ApplicationFiled: July 10, 2006Publication date: January 25, 2007Applicant: Ritchie Engineering Company, Inc.Inventors: Ajit Ramachandran, Keith Sliger, Ronald Plasek

Publication number: 20070017245Abstract: An evaporator which enables respective side surfaces of an inner liner defining a storage compartment to be uniformly cooled to provide uniform distribution of temperature in the storage compartment. A refrigerator includes the evaporator positioned on an outer surface of the inner liner to absorb heat from the inner liner. The evaporator includes at least two side surface cooling portions respectively positioned on at least first and second side surfaces of the inner liner. The side surface cooling portion positioned at a downstream side to allow refrigerant of lower cooling capability to flow therethrough is longer than the side surface cooling portion positioned at an upstream side to allow refrigerant of higher cooling capability to flow therethrough.
