Abstract: A weight and noise reducing glovebox assembly made of an inner glovebox bin composed of a pair of thermopolymer fiber layers that work in concert to absorb noise and isolate noise and vibration providing a glovebox with improved NVH characteristics. The glovebox bin is formed of a three dimensionally chill formed structural layer composed of PET fiber to which is mated, preferably by needle tacking, an inner carpet layer also composed of PET fiber providing two stage noise, sound and vibration reduction. In a preferred embodiment, the inner PET fiber carpet layer is mated, preferably by needle tacking, to an outer structural moldable PET fiber substrate layer forming a two-stage sound, noise and vibration absorbing and isolating thermoformable blank that is chilled formed into a sound absorbing glovebox bin of one piece flip open construction that is lighter in weight and which has reduced sound and noise generation and transmission compared to conventional hard plastic gloveboxes.

Abstract: A heat sink has a base plate to be clamped against a heat source and one or more heat pipes containing a phase change fluid. Each heat pipe has an elongated tubular evaporator fitted in a channel in the base plate, and a columnar condenser part perpendicular to the base plate forming a structural column for air heat exchange fins. The channel in the base plate is parallel to an edge. An additional channel or ridge is provided, also parallel to the edge, for receiving a clamp or spring clip to urge the base plate against the heat source. The base plate is inexpensively extruded with the parallel channels, ridges, etc., extending across the width of the base plate parallel to the edge. The heat sink has a minimum number of inexpensive parts yet is highly thermally efficient.

Abstract: A heat pipe system including a heat transfer block and a heat pipe coupled to the heat transfer block by a clip. By utilizing a clip to couple the heat pipe to the heat transfer block, a higher degree of thermal coupling may be achieved, thereby allowing more heat to be transferred from the heat transfer block to the heat pipe. The heat pipe system has particular application in transferring heat away from heat-producing electronic components, such as computer chips.

Abstract: A heat transfer device such as a heat sink has one or more heat pipe tubes mounted in a base plate. The heat pipe tubes have a working fluid in a vessel with a wicking material between an evaporator and condenser. The heat pipe traverses a through opening in the base plate and extends along a receptacle in the base plate facing the heat source, this portion preferably defining the heat pipe evaporator. The heat pipe has legs extending perpendicularly from the base plate, and preferably hold spaced heat transfer fins, the legs forming the condenser part of a stacked tower of fins on the base plate. Preferably two or more heat pipes are provided in the form of U-shaped or L-shaped tubes that are flattened along the underside of the base plate to bear against the heat source.

Abstract: An apertured flexible membrane (10) extends over a domed support (11). A central gas supply tube (50,82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

Abstract: The device is a hollow annular member bounding a liquid flow passageway. The member has a gas inlet and a row of apertures around the throat of the passageway to emit gas bubbles into the liquid to induce an upward flow of gasified liquid. The base of the hollow is weighted and the device is freely suspended by a line in the liquid. The suspending line passes freely through a horizontal tube suspension point effectively rigid with the member and a substantial distance above the member. This improves stability of the device against bodily movements and oscillations due to flow reactions, and enables level placement of the suspended device in a desired location.

Abstract: A gasification device having an overall density greater than that of water is suspended by chains over six foot down in a body of waste water about nine foot deep in a treatment vessel of a waste water treatment plant. The device is about one and a half foot tall and one and a half foot in diameter. The device is ring-like to define a generally annular enclosed chamber for receiving, through an inlet, gas to be introduced into the waste water. The longitudinal axis passing through the plane of said ring is vertically oriented. The central opening of said ring defines a passageway for induced upward flow of the water. A constriction about six inches long and six inches in diameter is defined at the middle of the passageway and is provided with a circumferential row of 5/16 inch holes communicating with the annular chamber. As gas flows into the constriction from the holes the resulting ascending bubble stream induces flow of water upwardly through the passageway.
