Abstract: A service riser (10) comprises a steel jacket (11) around a polyethylene pipe (12) which terminates in the riser at a transition zone (20). The transition zone (20) comprises a retainer sleeve (30) inserted in the end of the pipe (12) and sealed thereto by an O-ring (38). The retainer sleeve (30) extends out of the pipe (12) and is provided with grooves (46) separated by lands (48) on which an elastomeric sealing band (52) is received. The tube (11) is swaged down forming a swage groove (56) around the retainer sleeve (30) compressing the gasket (52) to a large extent over the lands (48) and a lesser extent over the grooves (46), the ideal compression for the gasket (52) being arranged somewhere between such degrees of compression.

Title: New atpase assay
Inventor: WHITE PETER
IPC: C12Q1/42
Filed: 2000-06-15
Abstract: The present invention uses the principle that phosphomolybdate binds to hydrophobic surfaces to isolate the phos-phomolybdate complex from other phosphate-containing molecules and further uses the SPA concept to bring a radiolabeled phos-phomolybdate complex in close contact with a scintillant for measurement by scintillation counting. Generally, the present invention provides an assay for detecting and measuring the amount of orthophosphate (Pi) in an aqueous reaction mixture, wherein the amount of Pi released is separated from the reaction mixture by: adding a solution of molybdate to the reaction mixture to form a phosphomolybdate complex; and contacting the phosphomolybdate complex with a hydrophobic surface, wherein the surface is capable of being separated from the aqueous reaction mixture to allow measurement of the Pi. Particularly, this invention provides an assay for measuring the ATPase activity of enzymes, more particularly, the HPV El helicase.

Patent CA-2379243-A1 (CA)
Inventor: GMEINER PAUL
IPC: F26B21/14
Filed: 2002-03-26
Abstract: The apparatus serves for drying solid insulation of an electrical device (40) by means of the heat of condensation emitted by the vapor of a solvent. It has an evacuable autoclave (10) accommodating the solid insulation, as well as an evaporator (20) producing solvent vapor, an evacuable condenser (50), connected to the autoclave (10), for condensing a solvent led out of the autoclave (10) and a vapor mixture containing water, and a heat recuperator (30). In the heat recuperator (30), the solvent acts as heat-absorbing medium and the vapor mixture as heat-emitting medium.        In order to keep the energy requirement of this apparatus low, a heat recuperator (30) exposed to the heat-emitting action of the vapor mixture is arranged in the autoclave (10). Solvent led to the evaporator (20) can thus absorb heat from the drying process in a particularly effective fashion. At the same time, by reducing the heat of the vapor mixture led out of the autoclave (10), only low requirements are made of the condenser (50) and a connecting conduit (51) between the autoclave (10) and the condenser (50). The drying apparatus can therefore simultaneously also be produced cost-effectively.

Abstract: The present invention is directed to an end stop (134) for a thermoplastic bag (120) having a reclos-able fastener (121) at the open top end of the bag. The reclosable fastener (121) comprises a pair of interlocking fastening strips (130, 131). The end stop (134) is config-ured to facilitate snap fit insertion onto the fastener strips (130, 131) and includes a top portion and a pair of de-pending side portions (172, 174) that straddle the fastener (121). The side portions (172, 174) further include in-wardly directed tab and shoulder structure (198, 202) that engage the reclosable fastener and prevent the end stop from being inadvertently pulled off in a transverse direc-tion in order to hold the end stop in place prior to being bonded to the bag. The bonding step is preferably accom-plished by ultrasonic welding. In the case of the line pro-duction of thermoplastic bags wherein a continuous web of plastic material is moved from one station to the next, the invention allows for the positioning of the end stop onto the reclosable fastener at a first station and the bond-ing of the end stop to the bag at a second station. The positioning and bonding steps may be performed simul-taneously.
