Abstract: A downhole pump system allows fluid to be pumped from a well to the surface through a production tubing string, while also allowing the downhole pump 10 to be retrieved to the surface while the production tubing string remains in the well. The downhole pump may include a hold down housing 12, a mandrel 14, a drive coupling 18, and a lifting nut 20. The pump is driven by a drive rod, which conventionally extends from the surface to the downhole pump. Axial movement of pump components may be prevented by a spring lock mechanism 24, while torque transmitting surfaces 26 prevent rotation of the pump housing 12 with respect to a landing nipple 25.

Abstract: A pilot tone generator receives optical energy from an optical communication medium carrying a plurality of optical signals. Each optical signal carries data modulated at a unique wavelength and further modulated with a unique identification signal. The identification signal has an amplitude corresponding to an optical power of the associated optical signal. The pilot tone receiver detects each identification signal from the optical energy received and determines its corresponding amplitude. The pilot tone receiver calculates the optical power of each optical signal in the optical energy in response to the amplitude of the associated identification signal.

Abstract: A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.

Abstract: Output circuits that provide compatibility with various input and output voltage levels without sacrificing performance. A pull-up (P12) on an output terminal is gated by an internal node (PD), and the invention encompasses various circuits and means for placing a data input signal on this internal node (PD). One embodiment includes a level shifter (100) on the data input path, while also providing an alternative path through the output circuit that bypasses the level shifter. When the input data value goes high, the alternative path quickly places an attenuated high value on the internal node.  The level shifter then becomes active and raises the voltage on the internal node to the output power high level, ensuring that the output pull-up (P12) is completely off.

Abstract: An aluminum container (10) is comprised of a base portion (12), a substantially vertical wall portion (14) extending upwardly from the base portion (12), a transition portion (16) extending from the wall portion (14), and a neck portion (18) extending from the transition portion (16). The neck portion (18) is tapered and has an upper end having a wall thickness that is preferably less than the thickness of the wall of the remainder of the neck portion. The upper end of the neck portion (18) may also be chamfered. The aluminum container (10) may be combined with a threaded sleeve (22) to form a receptacle, whereby the inner surface has a taper complementary to the taper of the neck poriton (18) so as to form a friction fit with the neck poriton (18). The sleeve (22) may also have a notch (32) formed in the periphery of its upper outside surface. When the upper chamfered end (20) of the neck (18) is curled, the neck portion (18) extends over a top end portion of the sleeve (22) and terminates in the notch (32) in the sleeve. Methods of manufacturing such a container are also disclosed.

Abstract: An improved subset-difference method is provided. The improved method uses the value of a current content key to help generate the requisite difference keys.  The requisite difference keys are then used to encrypt the next content key which will be delivered only to users who are supposed to remain in the group.  Users who have the current content key are then able to generate the requisite difference keys which they can then use to decrypt the next content key. Using the decrypted next content key, the users are then able to continue to receive contents. Since previously revoked users do not have the current content key, they are unable to determine the next content key and thus are prevented from receiving future contents.

Abstract: Contaminated waste streams or soil or sludge is subjected to a first treatment stage with an acid liquor at a pH below 2 and at a solids content from 5 to 30%; then the liquid and solid phases from the first treatment stage are separated; the solids from the first treatment stage are mixed with a fresh acid liquor at a pH below 2 and a solids content from 5 to 30%; the liquid and solid phases from the second treatment stage are separated; the liquor separated from the first treatment stage is reacted with a base to precipitate the metals; the precipitated metals are separated and the liquor is recycled for reuse in the process; the solids separated from the second treatment stage are neutralized to adjust the pH to a level acceptable for a soil conditioner or fertilizer or other customized products; and the liquor from the second stage is used as the acidic liquor in the first treatment stage . Where the sludge contains hydrogen sulfide the treatment stages are conducted in closed vessels containing a source of ozone in the head space to convert the hydrogen sulfide into a soluble sulfurous or sulfuric acid. The process has the advantage of avoiding any liquid effluent.
