Abstract: A transmission vent assembly includes an apparatus having a central, internal passage extending therethrough. The internal passage has a larger diameter portion defining a pocket. A filter is disposed in the pocket to condense and return fluid to the transmission through the internal passage. The apparatus includes a shoulder adjacent the upper surface and a double lead thread initiating at the shoulder and terminating at a lower end. The assembly further includes a cup-shaped cap, press fittingly disposed over the apparatus. The cap and shoulder define an annular cavity and the cap and the double lead thread define first and second threaded passages. The cap includes an outward impression in the closed end which cooperates with the upper surface of the apparatus to define a connecting passage. Two bi-directional air flow paths extend between the transmission and the atmosphere through the internal passage, connecting air passage, annular air cavity, and each of the two threaded passages.

Abstract: A vacuum apparatus for easily forming a vacuum in any bottle, container or the like and for providing a stable sealing. A lower cylindrical member together with a disc member forms a space portion in which a vacuum or an atmospheric pressure is applied, and the lower portion of an upper cylindrical member is inserted in the space portion and divides the space portion into upper and lower spaces. With a downward movement of the upper cylindrical member, the upper space expands and draws air inside of a bottle, and with an upward movement thereof, the air introduced into the upper space is vented outside. At this time, a check valve is selectively opened and closed and is operated by a pressure difference applied thereon. By repetitive reciprocating movement of the upper cylindrical member, a high vacuum is formed in the bottle and is sealed by the check valve. The apparatus is adaptable in a vacuum bottle, a medical suction instrument or the like.

Abstract: An air bleed device for a rigid closed housing having a vent hole in a vehicle power transmission system has a baffle portion and a vent portion, connected through a neck portion. In use, the baffle portion is positioned inside the housing and is significantly larger than the vent hole, so it may not be deformed sufficiently to pass through the vent hole. The baffle portion is a pair of planar pieces held in spaced apart relationship by a wall portion which runs along the periphery of the planar pieces and leaves an opening to give access to a plenum between the planar pieces. An outer surface of one of the planar pieces rests against the inner wall of the housing.

Abstract: A lid for a cooking vessel such as a pot. The lid is circular and has a central region and a peripheral region. At least one aperture is disposed within the central region of the lid, thereby enabling hot air and steam to pass through the lid. A plurality of rib elements are disposed on the top of the lid, wherein the various rib elements define a pathway from the apertures in the central region to the peripheral region. The rib elements all terminate in the same plane. As such, a cooking vessel can be placed on top of the lid and the rib elements will support that cooking vessel in an even manner. As hot air and steam from a cooking vessel rise up, that hot air and steam passes through the apertures in the lid. The hot air and steam then passes through the pathways on the top surface of the lid, thereby allowing that hot air and steam to heat a second cooking vessel placed on the lid.

Abstract: A breather box attaches to the exterior wall of an electrical enclosure. An upper breather opening in the box connects with a vent opening in the wall. A lower breather opening in the box is shielded by a wall spaced therefrom to prevent water entry. A labyrinth in the interior of the box forces ascending water through a series of sharp turns and through a series of constrictions which are followed by expansion chambers. The labyrinth terminates at a liquid exit adjacent the upper wall of the breather box, forcing water to substantially fill the breather box before it can enter the enclosure.

Abstract: An electrical enclosure lid composed of several elongated members nested in such a way that a tortuous air channel is created between each member. The air channel allows heat generated by internal electrical components, such as large power transformers, to pass out of the lid to facilitate convection cooling of the enclosure. Due to the labyrinthine air channel, flames potentially generated inside the enclosure are hindered from passing outside the enclosure. Drainage holes are included on the sides of the lid to allow water to pass over the lid without entering the enclosure. The design is optimized for harsh environments such as a mining operation where large amounts of power are needed in close proximity to workers. The nesting structure provides strong structural support to protect the enclosure in case of a rock fall or a cave-in.

A shroud extends laterally from one side of the cap to a point beyond the sensor package and further extends down below the upper surface of the package. The shroud is open at the bottom to afford an air passage to the vent as well as a baffle against spray.

Abstract: The present invention features a breather cap for use in venting an oil reservoir. The cap vents high-velocity air flowing out of the oil reservoir, entraining the droplets of oil that are suspended in the escaping air. The breather cap is designed to slow the speed of the escaping air. This slowing mechanism is usually a large-volume chamber that is typically placed within the bottom of the cap. The air is directed against a deflector plate or a deflecting surface on top of the chamber. This deflected air deposits the tiny droplets upon the deflection surface. The separated oil is caused to pool or accumulate and drip back into the bottom of the chamber and then into the oil reservoir. The purified, lighter air thus rises above the deflector and is then vented through exit holes located in the top or side of the cap.

Abstract: An insert for a nursing bottle is disclosed. It is placed between the bottle and the nipple. The insert has a channel that communicates with the air passage holes in the nipple. The channel itself has air passage holes that are sized to allow air into the bottle but prevent the liquid in the bottle from exiting. This arrangement prevents the creation of a vacumn in the bottle when the liquid exits through the nipple.
