A mixed-phase fluid stream is divided into a vapor stream and a liquid stream by discharging the mixed-phase stream tangentially into an outer annular volume in which the liquid falls to a lower portion of the apparatus for removal. Released vapors pass through perforations in the inner wall of the annulus and then rise through liquid-vapor contacting means before leaving through the top of the apparatus. The vapors passing through the liquid-vapor contacting means preferably contact a hydrocarb...

A well effluent stream passes into a high pressure separator tank where liquids separate from gas. A very small amount of gas from the well effluent is fed through a thermostat to a glycol seal pot to control a closed glycol heating system for the high pressure separator. The closed glycol system receives its thermal energy from heat exchange from a separate process glycol system.

Picture inversion in display devices based on the twisted pneumatic effect is prevented by choosing a twist angle .phi.T such that 70.degree.<.phi.T<90.degree., and an angle .alpha. between the direction of polarization of one of the polarizers and the associated direction of orientation such that: 30.degree.+.phi.T/2<.alpha.<60.degree.+.phi.T/2.

A deformable drive shaft includes drive side and driven side connections and a flexible intermediate section interconnecting the connections, the flexible intermediate section being formed of an alternating sequence of disc-shaped rigid segments and disc-shaped flexible segments, the formed rigid segments having surfaces with complementary funnel-shaped projections and funnel-shaped depressions formed thereon, the funnel-shaped projections of a given formed rigid segment extending through an adj...

The instant invention relates to new glass-ceramic articles containing alkaline earth tungstate crystals. More particularly, the invention pertains to a phototropic article comprising a glassy matrix containing an alkaline earth tungstate doped with bismuth. The invention especially pertains to glassy matrices of boric oxide or silica.

A multilamp photographic flash unit, the lamps of which are of the percussive primer type, having self-contained elements in the form of a folded torsion spring for firing the lamps. The folded torsion spring is formed in the shape of a hairpin having first and second segments joined by a light. One of the segments has a striker member thereon for firing the lamps. The spring is cocked by crossing the segments over one another and thereafter restraining the striker in the biased condition.

A horizontal crankshaft rotary compressor in a housing having a discharge muffler formed with a plurality of interconnected communicating volumes with a discharge tube extending through the housing in which an oil draining tube has one end communicating with the lowest muffler volume where oil accumulates and the other end with the interior of the shell at a point above the oil in the bottom of the housing.

A capacitance-type electrostatic transducer is provided that can be operated in an environment where it may be subjected to excessive mechanical vibrations. Unwanted gain variations and/or spurious electrical signals produced by said transducer when operated in such an environment are precluded, at reduced cost, by mechanically attaching the electrically conductive transducer spring that urges the backplate into cooperative engagement with the vibratile diaphragm of said transducer, to said tran...

A novel apparatus for stripping and absorption of useful gases and vapors and/or averse gases and vapors, which comprises a unit consisting of A. a stripping part for the aforementioned gases and vapors in which an inert gas is contacted in a cross-flow with the solution containing said gases and vapors, and B. an absorption part for the gases and vapors in which the resulting inert gas containing the gases and vapors is contacted in a cross-flow with a liquid absorbent or A combination of the u...

A combined muffle and spark arrester for use with small internal combustion engines. The muffler includes two expansion chambers through which engine exhaust is passed and a hat-shaped spark-arresting screen positioned within the second chamber. The screen removes particles from the exhaust having a size greater than the screen mesh to prevent the discharge of potentially dangerous sparks. A curved heat shield is supported on the muffler by a plurality of U-shaped brackets which are projection w...
