摘要: Substantially linear olefin polymers having a melt flow ratio I.sub.10 /I.sub.2,.gtoreq.5.63, a molecular weight distribution, M.sub.w /M.sub.n, defined by the equation: M.sub.w /M.sub.n .ltoreq.(I.sub.10 /I.sub.2)-4.63, and a critical shear stress at onset of gross melt fracture of greater than about 4.times.10.sup.6 dyne/cm.sup.2 and their method of manufacture are disclosed. The substantially linear olefin polymers preferably have at least about 0.01 long chain branches/1000 carbons and a molecular weight distribution from about 1.5 to about 2.5. The new polymers have improved processability over conventional olefin polymers and are useful in producing fabricated articles such as fibers, films, and molded parts.

摘要: A vacuum breaker assembly includes an outlet tube having circumferential air ports and a vacuum breaker sleeve formed of a flexible elastomeric material positioned within the outlet tube. Conventionally, a stiffening funnel will be positioned within the vacuum breaker sleeve. The elastomeric sleeve has an inlet end and an outlet end and is located within the outlet tube adjacent the spaced air ports. The vacuum breaker sleeve has lip seals in the interior intermediate the inlet and outlet ends, with the lip seals opening in response to water pressure at the inlet end to permit water to pass through the vacuum breaker assembly. There are peripherally spaced projections on the exterior of the vacuum breaker sleeve adjacent the outlet end to space the exterior of the sleeve from the outlet tube. There is a tapered lip seal extending axially from the outlet end of the vacuum breaker sleeve, with the lip seal being downstream of the spacing projections. The tapered lip seal is outwardly movable into closing contact with the outlet tube in response to back pressure downstream of the vacuum breaker assembly, such closing contact preventing water flow through the air ports of the outlet tube.

摘要: A vandalproof cap assembly for closing an access opening in a plumbing fitting includes a plastic sleeve formed and adapted to be normally non-removably attached to the plumbing fitting about the access opening. The plastic sleeve has a plurality of outwardly extending flexible projections. There is a cap with a smooth exterior and an interior recess which is snapped upon the sleeve so that the sleeve projections interlock with the cap recess. When so mounted the cap is freely rotatable relative to the sleeve, and can only be removed from the sleeve with a tool and specific knowledge as to use of the tool.

摘要: A multiple well tissue culture plate (10) having a plurality of opened bottomed wells (36) with a semi-permeable membrane (20) across the bottoms of a plurality of such wells (36). The multiple well tissue culture plate (10) is placed in contact with the basal medium (26) contained within the basal medium reservoir (12) to allow for exchange of nutrients and waste products between the basal medium (26) and the culture medium (22) across the semi-permeable membrane (20). The dialyzed multiple well tissue culture plate (50) provides dialysis of each individual well within the multiple well tissue culture plate (10) thus eliminating traditional exchange of culture medium to maintain proper culture conditions.

摘要: A pressure control system for a bioreactor of the type having a gas space and a cell culture space therein is supplied with a gas such as oxygen separately from the supply of liquid nutrient media. The pressures in the gas space and the pressure in the cell culture space are controlled so that a higher pressure is maintained in the cell culture space than in the gas space to prevent displacement of the liquid nutrient media.

摘要: A sensor-activated, battery-powered toilet room flush valve has a body with an inlet and an outlet. There is a valve seat in the body and a diaphragm which closes upon the seat to control flow between the inlet and the outlet. A cover mounted on the body defines a pressure chamber with the diaphragm and there are a sensor, solenoid and battery mounted on the cover and connected for operation of the flush valve. There is a passage in the cover connecting the pressure chamber and the outlet. Operation of the solenoid opens the passage to relieve pressure in the chamber to the outlet whereby the diaphragm moves off its seat to open communication between the inlet and outlet. A stop is positioned within the chamber and attached to the diaphragm to limit its movement toward the cover, which in turn controls the volume of water passing through the flush valve prior to closure of the diaphragm upon its valve seat. The stop is adjustable from the outlet side of the valve.

摘要: An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is peripendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maxium time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry. Any incremental interruption in the reflected signal which does not exceed the period of permitted interruption, restarts the commencement of the timing of the maximum period of continuous detection.

摘要: A faucet for automatic operation defining a base and an elongated cantilvered spout body provided with a discharge outlet. A sensing means for automatic operation in the form of an emitter and detector are mounted on the spout body intermediate the base and discharge outlet. The emitter and detector are positioned on the longitudinal center of the spout body and provide a concentrated zone of effective detection disposed intermediate the area of discharge from the faucet and the base. The zone shape is transversely elongated relative to the longitudinal center of the faucet spout body.

摘要: A method of culturing cells by providing a highly gassed media on a continuous basis to cells grown in a hollow fiber cartridge includes entraining the media with gas above the gas solubility level of the media. The media is then permitted to rest in a substantially quiescent state so that non-solubilized gas leaves the media. The media is then pressurized prior to delivery to the hollow fibers sufficiently so that the pressure drop and/or flow disturbance in the cell culturing device does not decrease the gas solubility level of the media below the media's gas saturation point.
