International Classification:

F04B 5300

US Classification:

417312, 417902, 417415, 417313, 181233, 181249, 181248, 181403, 181252, 62296, 62 92, 62 79

Abstract:

A resistive muffler attenuates sound generated by the gas intake and suction valve during compressor operation of a refrigerant compressor. The resistive muffler is assembled inline with the suction gas flow of the compressor and is positioned within the compressor housing. The resistive muffler attenuates the sound generated by the compressor during its operation as refrigerant gas is drawn into the compressor from an evaporator and passes through the resistive muffler in transit to the suction valve and hence to the region of the compressor where the gas is physically compressed. The resistive muffler includes a muffler housing having an intake end and an exhaust end. An acoustic foam assembly is incorporated into the muffler housing. The acoustic foam assembly is selected on the basis of its ability to absorb sound over a broad range of frequencies and is the muffler containing the acoustic foam is assembled within the compressor so that the sound does not bypass the muffler and transmit significant amounts of the sound to the compressor housing. The acoustic foam remains chemically inert when exposed to the compressor fluids at elevated temperatures of operation, and retains its ability to absorb sound over a broad range of frequencies even when saturated with compressor fluids.

Assignee:

Ultrablend, LLC - Charlotte NC

International Classification:

B65B 7/28

US Classification:

53329, 53324, 53328, 100902

Abstract:

A closer for pressing a lid onto a container includes a presser foot mounted for reciprocating movement into and out of force applying engagement with the lid; an actuator moveable between retracted and extended positions; and a force multiplying assembly disposed in operative relationship intermediate the presser foot and the actuator for multiplying an input force from the actuator to a predetermined maximum lid pressing force at the extended position.

Appl. No.:

11/130898

Inventors:

Steven Marshall - Fort Mill SC, US
Martin Miguel Salas - Charlotte NC, US

Assignee:

Ultrablend LLC - Charlotte NC

International Classification:

B01F 9/04

US Classification:

366217, 366605

Abstract:

An apparatus for mixing material in a container includes a platform mounted for simultaneous movement on at least two axes and for supporting a container containing material to be mixed. A motor can be operatively associated with the platform to move the platform on the two axes. A container holding assembly having a vertical extent can be carried by the platform, and is moveable between a closed position in which the holding assembly is positioned proximate the container to retain the container on the platform during mixing operations, and an open position in which the holding assembly is positioned away from the container so that the container can be removed from the platform without lifting the container over the vertical extent of the holding assembly. The platform can be contained within a housing having a low profile opening such that the container can be removed without elevating the container.

International Classification:

F04B039/00
F04B053/00

US Classification:

417540000, 417312000

Abstract:

A muffler system for a compressor includes an expansion chamber muffler for reducing pressure pulses at the compressor's fundamental pulsation frequency and a side-branch muffler for filtering high-frequency pressure pulses. The expansion muffler is positioned along the compressor discharge stream at a location that maximizes pulsation reduction at the compressor's fundamental pulsation frequency. The side-branch muffler is tuned to the frequency at which the pulsation reduction for the expansion muffler is at a minimum.

International Classification:

B05B 15/02

US Classification:

239112

Abstract:

An apparatus for providing vapor to at least one liquid dispensing nozzle to prevent liquid at the nozzle tip from drying out between uses. The apparatus comprises a water source, a reservoir, a vapor generating source for generating vapor from water, a chamber for maintaining the vapor, and an opening defined through a chamber wall for exposing the at least one nozzle to the vapor when the at least one nozzle is in a storage position between uses.
