Patent CA-2385902-C (CA)
Title: Difusser saddle connection
Inventor: KELLY JEFFREY T
IPC: B01F3/04
Filed: 2002-05-10
Granted: 2005-08-23
Abstract: A diffuser saddle connection is used for the attachment of diffusers on submerged air laterals in systems that treat municipal and industrial waste water. A top saddle surface and a bottom saddle surface enclose a portion of a feed pipe. A  spout attached to the bottom saddle surface is solvent-welded to a tee, which is threadedly engaged to a diffuser. Flexible bushings on a nipple attached to the tee relieve stress on the connection between the diffuser and the diffuser saddle connection. An open end allows water to flow into the diffuser pipe to provide hydrostatic equilibrium and to reduce buoyancy.

Granted: 2007-09-18
Abstract: A tape structure and/or closure system particularly useful with cylindrical insulation segments for pipes. The tape structure provides both a temporary and a permanent closure. The tape structure includes a substrate and a layer of pressure sensitive adhesive disposed on both sides of the substrate. One of the layers of pressure sensitive adhesive is covered by a release liner, while the other layer of pressure sensitive adhesive is exposed. The exposed layer of pressure sensitive adhesive is applied to one of either the underside of a flap covering a slit in the insulation jacket, or to the outer surface of the insulation jacket. The release liner is divided into two portions, one of which is narrow with respect to the other portion. The narrow portion of the release liner is removed, and a narrow strip of the second layer of pressure sensitive adhesive is attached to the other of either the outer surface of the jacket, or the underside of the flap to form a temporary closure. When it is desired to insert a pipe into the insulation segment, the temporary closure is broken by pulling the flap away from the insulation jacket. The pipe is then inserted, and a permanent closure is effected by removing the other portion of the release liner and attaching the second layer of pressure sensitive adhesive to the other of either the underside of the flap or the outer surface of the insulation jacket.

Abstract: A table or desk assembly (20) includes a base having a pair of legs (24), a worksurface (22) supported by and between the pair of legs, and a rapid, counterbalanced height adjustment mechanism interposed between the legs and the worksurface for providing adjustment in the elevation of the worksurface. The height adjustment mechanism includes a pair of high lead rotatable threaded rods (32) engaged with a mating stationary threaded member (33) associated with each leg. A handle (36) is engageable with one of the threaded rods for imparting rotation to the threaded rod, and a synchronizing arrangement, such as a sprocket (38) and chain system (40), is interconnected with the other of the threaded rods for rotating the threaded rods together. A lift assist or counterbalancing mechanism applies an upward bias, such as to the worksurface, to counteract the weight of the worksurface and any loads supported by the worksurface. The counterbalancing mechanism may be in the form of a cylinder assembly (54) having a biased retractable and extendible member, which is interconnected with each of the threaded rods via a cable (66) and pulley (68) arrangement. Alternatively, the lift assist or counterbalancing mechanism may be in the form of constant force spring arrangements (76), each of which has an extendible and retractable member. A retainer arrangement (90) is interposed between the crank or handle member (36) and the worksurface, for preventing inadvertent rotation of the threaded rod and thereby maintaining the elevation of the worksurface.

Inventor: STILP LOUIS A
IPC: H04W4/90
Filed: 1999-12-13
Granted: 2008-06-10
Abstract: A method for calibrating and correcting for station bias in a receiver system is provided for use in a wireless location system (WLS), wherein "station bias" is the finite delay between when an RF signal from a mobile transmitter reaches antennae of the system and when the same signal reaches a wideband receiver of the system. The receiver system comprises an antennae array, a filter, cabling coupling the filter to the antennae array, and a wideband receiver operatively coupled to the filter. The method comprises the steps of: measuring the length of cable from the antennae to the filter and determining the corresponding delay associated with the cable length; injecting a known signal into the filter and measuring the delay from the filter input to the wideband receiver; and, combining the delays and using the combined delays to correct subsequent location measurements. In a GPS - based calibration scheme this method may further include correcting for cable lengths associated with the GPS. The WLS may include a plurality of signal collection systems (SCS's) and be overlaid on a wireless communications systems such that a plurality of the SCS's share an antenna with a base station of the wireless communications system. An externally generated reference signal may be used to monitor changes in station bias that may arise due to aging and weather.
