Granted: 1998-01-27
Abstract: A packingless gate valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate in the valve closed condition.  Each sleeve unit has a plurality of compression holes extending axially and arranged at intervals relative to the circumference of the sleeve.  An encircling stiffening ring of harder material is encapsulated in each sleeve so as to be positioned at the  inner end of  the compression holes.  The compression holes may be left empty or, alternatively, may be sealed with plastic plugs, filled with closed cell foam or mechanical springs.  The compression holes  provide  space  for the  displaced volume  of  sleeve elastomeric material to flow into during opening and closing of the gate.   The gate valve construction of the present invention results in no leakage to the outside when the valve is fully open and no leakage to the outside or past the gate internally when the valve is fully closed.  A lockout device of the invention has alternative positions for preventing the valve from opening or closing.  In an alternative embodiment of the gate valve, the inner axial sealing end of each sleeve is located radially inwardly as compared to the location of the stiffening ring.  As a further alternative, a groove is located along the radially inner surface of the sleeve in an arc of approximately 120 degrees, with the arc extending from the four o'clock to the eight o'clock position.

Title: Clip for surgical purposes
Inventor: SCHULZE DALE R
IPC: A61B17/068
Filed: 1993-05-07
Granted: 2005-01-04
Abstract: The invention relates to a clip for surgical purposes, made from bendable wire-like material. Conventional clips have an essentially rectilinear base from each end of which a limb projects. Upon application in endoscopic operations, i.e. when the clips are pushed forward through trocar cannulae, it is disadvantageous that the rectilinear base can only be so long that it can be pushed forward transversely through a trocar cannula. As a result, only small clips have been usable thus far with pre-set trocar diameters. According to the invention, a clip is so designed that the base is shaped bent backwards, starting from its centre section, on both sides, opposite to the direction of the limbs (42, 44), so far that the ends (12, 14) of the base touch or come close to each other, base (10) and limbs (42, 44) forming an essentially .OMEGA.-shaped contour, The bent-back configuration effects a substantial reduction in the lateral extension of the clip when it is pushed forward through the trocar cannula, so that endoscopically larger clips than usual can be set with a suitable clip setter.

Granted: 2001-05-15
Abstract: This disclosure relates to aeration, especially biological treatment of wastewater with fine pore diffusers and in situ cleaning of these diffusers with liquid and/or gaseous cleaning fluids supplied to the diffusers through cleaning fluid channels that respectively have separate and direct connections to plural diffusers. Aeration and cleaning of fine pore diffusers is described in which cleaning fluid is conducted from a source of such fluid to a multiplicity of diffusers via a flow path which is separate from a flow path which conveys aeration gas to the diffusers. Methods of fabricating aeration gas distribution assemblies are also disclosed. One such method involves securing to an aeration gas distribution conduit at least a portion of a cleaning fluid distribution channel which includes one or more cleaning fluid distribution conduits and further includes connectors coupled to the cleaning fluid distribution conduits. The connectors are spaced longitudinally along the cleaning fluid distribution conduits at the same intervals as, and are connected to, the plenums. Another method comprises fabricating a cleaning fluid conduit having longitudinally spaced tee connectors coupled thereto. An aeration gas conduit having longitudinally spaced plenums secured thereto is fabricated, and such plenums are have holes for receiving the tee connectors coupled to the cleaning fluid conduit. The invention effectively and economically brings cleaning fluid in contact with diffusion elements without lengthy interruptions in wastewater treatment, complicated processing sequences and back-flow of wastewater through the elements, and can be used with diffusers having back-flow prevention capabilities, including membrane diffusers.

Patent CA-2113131-C (CA)
Inventor: FERGUSON KEITH
IPC: A61F5/441
Filed: 1994-01-10
Granted: 2003-05-20
Abstract: The ostomy bag includes a multi-stage filter system that provides contamination protection for a deodorizing filter in the system. The multi-stage filter system also includes a gas transmissible protection filter that is impassible to semi-liquid waste material. The protection filter is located in the ostomy bag to precede the deodorizing filter such that gaseous waste must pass through the protection filter before it passes through the deodorizing filter. In one embodiment of the invention wherein the ostomy bag has a single chamber, the protection filter is a two layer structure with different pore counts that overlay the deodorizing filter. In another embodiment of the invention wherein the ostomy bag has dual chambers, the protection filter, without overlaying the deodorizing filter, is disposed across the flow path of gaseous waste to the deodorizing filter such that any gaseous waste that reaches the deodorizing filter must flow through the protection filter. Thus semi-liquid waste material cannot contact the deodorizing filter since it cannot bypass the protection filter to reach the deodorizing filter.

Title: Motor-driven, spring-returned rotary actuator
Inventor: HIGHTOWER PETER C
IPC: F24F13/14
Filed: 1994-02-01
Granted: 2002-09-17
Abstract: An electric motor acts through a gear train to rotate an output shaft in one direction while a torsion spring rotates the shaft in the opposite direction when the motor is de-energized. When the output shaft stops abruptly at a limit position after being rotated by the spring, a lost-motion drive connection permits the output gear of the drive train to rotate relative to the shaft in order to dissipate kinetic energy through the gear train and to avoid impact loading of the gear train and the motor.
