20090051160 | BONDING SOCKET FOR HIGH PRESSURE MEDICAL HOSE - A socket for receiving a medical hose or tubing. The hose may be, for example, reinforced medical hose. The socket includes an internal conical feature which enters an end of the hose when the hose is inserted in the socket. The conical feature compresses the hose, and places the hose wall under radial compression, which tends to keep the hose retained in the socket, even during a high pressure application The compression creates a barrier seal between the hose lumen and the conical feature to prevent fluid from contacting the very end of the hose. As such, there is less longitudinal force attempting to push the hose out of the socket. If a reinforced hose is used, the compression places the jacket bond line and each fiber under compression in order to raise resistance to pressurized fluid entry, should the barrier seal be breached | 02-26-2009 |

A special coupling has opposing tapered ends. Each of the tapered ends slopes inwardly from an inner extent to an outer extent thereof to thereby form a respective mouth opening of the body. Each tapered end of the coupling has a specially contoured surface which is made up of a series of alternating helical spline wedges. The wedges are oppositely tapered from an inner extent to an outer extent thereof, whereby the helical spline wedges form an alternating series of lands and grooves on the body as viewed from the respective mouth openings. The two opposing pipe ends have mating engagement surfaces which engage and mate with the contoured surfaces of the coupling as one pipe end is pushed toward the other during assembly. | 09-22-2011 |

The drain includes a receptacle including a plurality of downwardly opening bosses and the collar includes a plurality of bosses and at least one support member is adapted to be received within the bosses to stabilize the receptacle body relative to the stabilizing collar and the floor. Engagement members cooperate with adjustment members to adjust the diameter of the collar with respect to the pipe. The receptacle body is attached to the pipe and the support members are adjusted so that they contact the receptacle body and therefore provide support to keep the receptacle body at the same slope as the floor level. | 02-02-2012 |
20120169040 | FERRULE FOR MAKING FINGERTIGHT COLUMN CONNECTIONS IN GAS CHROMATOGRAPHY - A ferrule arrangement for use in sealing connections to gas chromatography columns includes a generally tubular metal ferrule with an axial bore to receive a fracturable column with a protective coating. The ferrule has a forward part that tapers to a tip region of the ferrule. A generally tubular former has a socket portion to receive the ferrule and further has an internal conical surface that, after such receipt, engages the forward part of the ferrule. A portion is provided on either or both of said ferrule and the former by which the ferrule and former may be directly or indirectly relatively moved together by application of finger force. The taper and the internal conical surface exhibit relative taper angles and the tip region of the ferrule is sufficiently radially thin whereby the application of finger force (i) is adequate to move the ferrule axially into the former to cause the conical surface to engage the tip region of the ferrule and to deform the tip region into sealing engagement with the protective coating of the column, but (ii) does not break the column. | 07-05-2012 |
20130020795 | PIPE COUPLING ASSEMBLY AND METHOD FOR PREVENTING LONGITUDINAL MOVEMENT OF COUPLING RINGS - A pipe coupling assembly for preventing longitudinal movement of first and second coupling rings disposed on first and second pipe sections is provided. The pipe coupling assembly includes a first clamping assembly disposed around a portion of an outer surface of the first pipe section and to abut against the first coupling ring. The pipe coupling assembly further includes a second clamping assembly disposed around a portion of an outer surface of the second pipe section and to abut against the second coupling ring. The pipe coupling assembly further includes a first threaded shaft coupled to both the first clamping assembly and the second clamping assembly to prevent longitudinal movement of the first and second clamping assemblies. | 01-24-2013 |
20140252755 | MULTIPOSITIONAL FITTING - A fitting assembly for connecting a first tube to a second tube includes first and second end fittings fixedly coupled to the first and second tubes, respectively. The first end fitting has a first aperture and a first sealing surface. The second end fitting is sized to be at least partially received within the first aperture and includes a second aperture extending through the second end fitting. The second end fitting further includes a second sealing surface. A seal is disposed between the first sealing surface and the second sealing surface. A lock fitting is slidingly associated with the second tube, and is also rotatable about the second tube. The lock fitting selectively engages the second fitting to compress the seal between the first and second sealing surface. | 09-11-2014 |

20080303267 | Fluid flow connector permitting forceful lateral separation - A fluid flow connector comprises a connector body which carries a first connector tube having a lumen for receiving a second connector tube when the connectors are joined. The first connector tube has a lumen and a lumen wall. The first connector tube typically has an end portion that carries a plurality of circumferentially spaced, outerwardly extending lugs to engage the second connector tube when connected. The fluid flow connector is made of a plastic having a flexural modulus that is low enough to allow deformation, permitting a connected, engaging second connector to pop loose from connection with the fluid flow connector when laterally struck, rather than breaking the fluid flow connector. Also, the first, fluid flow connector may optionally be frictionally retained in a retracted position where fluid flow is blocked through the connectors by a skirt of the second connector, which skirt has an inner diameter in frictional engagement with radially outer surfaces of the lugs of the first connector, for frictional retention of the connectors. | 12-11-2008 |
