Abstract: A process for making a multilayered article, the process comprising the steps of: (A) Providing a mold comprising: (1) A mold housing comprising (a) at least one injection port, and (b) defining a mold cavity within which are positioned two deformable, pre-molded polymeric sheets; and (2) A removable, hollow core equipped with at least one vent, the removable, hollow core positioned between and space apart from the two polymeric sheets; (B) injecting under high pressure a viscous, crosslinkable, thermoplastic polymer into the mold cavity between the two polymeric sheets and around the removable core, (C) Drawing a vacuum on the mold cavity through both the vent in the mold housing and the vent in the removable, hollow core before, during and/or after the polymer has been injected into the mold; (D) Forming a less than fully cured multilayered article in the mold cavity; and (E) Removing the less than fully cured multilayer article from the mold cavity.

Abstract: A filter assembly (10) including a first (12) and second (14) filtration element positioned in an abutting end-to-end arrangement along a common axis (X). Both filtration elements (12, 14) include a cylindrical housing (16, 16?) enclosing a filtration media and extending along the axis (X) between opposing ends, and an end cap (18, 20, 18?, 20?) located at each of the abutting ends of the filtration elements (12, 14) and comprising an annular surface (28, 28?) co-extensive with the housing (16, 16?) and an annular stepped edge (29, 29?). The first (12) and second (14) filtration elements are positioned with their end caps (18, 20?) directly engaged with each other so that the stepped edges (29, 29?) collectively form a continuous annular groove (31) about the periphery of the filter assembly (10). The annular groove (31) provides an effective means for handling filtration elements without increasing the overall length of end cap.

Abstract: A hydroclone including: a vortex chamber (24) in fluid communication with the inlet (14), a process fluid chamber (32) in fluid communication with the process fluid outlet (20), an effluent separation chamber (30) located between the vortex chamber (24) and process fluid chamber (32) and including an outer circumferential surface (23), a vortex flow barrier (34) located between the vortex chamber (24) and the effluent separation chamber (30), an effluent barrier (36) located between the effluent separation chamber (30) and the process fluid chamber (32) including at least one opening (42?) near the outer circumferential surface (23), and an effluent opening (38) centrally located within the effluent separation chamber (30) in fluid communication with the effluent outlet (18); wherein the effluent separation chamber (30) has a median distance (80) between the vortex flow barrier (34) and effluent barrier (36) which is adjustable.

Abstract: A dispensing device for dispensing compressed fluid from a can through a valve stem of the can has a hollow tube with a channel extending through it from an entrance end to an opposing dispensing end, a connector defining a conduit therethrough that is in fluid communication with the channel of the hollow tube and that attaches to a valve stem of a can, a plug located within the channel of the hollow tube that forms a sealing configuration within the channel when pressed towards the dispensing end of the channel, and a sleeve that wraps at least partially around the hollow tube and that has a protrusion that upon activating the sleeve extends through the dispensing end of the hollow tube and prevents the plug from establishing a sealing configuration with the hollow tube.

Abstract: A dispensing device (10) for dispensing compressed fluid from a can (100) through a valve stem (110) of the can, the dispensing device containing a hollow tube (20) defining a channel (22) there-through, a connector (40) defining a conduit (46) there-through that is in fluid communication with the channel of the hollow tube, a plug (30) located in the channel of the hollow tube that is able to move in the channel of the hollow tube and seal the hollow tube from fluid flow when pressed towards the dispensing end (24) of the hollow tube (22), a sealed port between the inside and outside of the dispensing device and a flexible and inelastic extension piece (50) attached to the plug and extending through the channel of the hollow tube and, optionally, the conduit of the connector then out from the dispensing device through the sealed port and capable of attaching to a can (100) to which the dispensing device (100) is connected.

Abstract: A patient support incorporates a lying surface and at least one siderail on at least one side of the support. The siderails are operable between a raised position, an intermediate position, and a lowered position. The siderails are biased along a first range of motion by a first biasing member, and are biased along a second range of motion by a second biasing member. In the intermediate position, the siderails may define a gap through which a patient can ingress or egress the bed. In the raised and intermediate positions, the siderails may define gaps between each other and/or between the siderails and a headboard and footboard, that are sufficiently small to prevent accidental egress, and sufficiently large to prevent pinching and entrapment.

Abstract: A patient support incorporates a lying surface and at least one siderail on at least one side of the support. The siderails are operable between a raised position, an intermediate position, and a lowered position. When unlocked and urged from the raised position to the intermediate position, a latching mechanism automatically locks the siderails in the intermediate position. When urged from the lowered position to the raised position, the locking mechanism permits the siderails to pass through the intermediate position without locking, and to subsequently lock at the raised position. In the intermediate position, the siderails may define a gap through which a patient can ingress or egress the bed. In the raised and intermediate positions, the siderails may define gaps between each other and/or between the siderails and a headboard and footboard, that are sufficiently small to prevent accidental egress, and sufficiently large to prevent pinching and entrapment.
