Title: Water heater foam stop apparatus and associated methods
Inventor: HANNING DAVID M
IPC: F24H1/18
Filed: 1993-07-19
Granted: 1999-01-05
Abstract: The storage tank portion of a water heater has an outwardly projecting threaded pipe coupling fitting and is disposed within a jacket structure that forms an enclosed insulation space around the storage tank, the outer end of the pipe coupling fitting being spaced inwardly apart from a pipe connection opening in the jacket structure.  A generally tubular foam stop  member having a convexly curved side portion is positioned within the insulation space before the space is filled by an injection process with a liquid foam insulation material. The foam stop member  receives the pipe coupling,  is axially pressed between the storage tank and the jacket structure, and forms a seal around the pipe coupling fitting and around the jacket structure pipe connection opening.  During injection of the liquid foam insulation material into the enclosed insulation space, the foam stop member  serves as a relatively small barrier that essentially precludes the liquid foam from escaping outwardly through the jacket structure pipe connection opening or entering the pipe coupling.

Granted: 1999-08-17
Abstract: An improved packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and, the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which frictionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism. Nips adjacent the load station and at the downstream end of the web feed mechanism have surface speeds exceeding the surface speed of the belts to maintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station. Other features include a cantilevered support of the web supply and bagger, a bagger support which functions as a plenum, an improved dancer assembly, and improved application of compressed air for bag opening.

Patent CA-2119199-C (CA)
Inventor: WILLHOFF STEVEN J
IPC: H04B17/00
Filed: 1994-03-16
Granted: 2003-05-27
Abstract: An appropriate handoff trigger is determined in a cellular system by maintaining both a long term representation of the received signal strength and a short term measurement of the current signal strength.      The long term representation is used as the initial trigger for a handoff condition. The averaging process removes the effects of short term fades in the signal that may cause a premature handoff decision due to these fluctuations. This initial trigger is then qualified by examining the short term current, value of the signal. The actual handoff trigger is only realized when both values indicate that the handoff threshold has been exceeded. This approach eliminates the occurrence of false handoff triggers caused by the historical bias that may exist from the long term averaging process. The short term signal strengths value is reported as the mobile station's signal for comparisons to the signal strength measured on the adjacent cells. Since this value represents the current measure of the signal, it provides a truer comparison with the current measurements made on the adjacent cells, and virtually eliminates delayed handoff realizations due to the long term average historical bias.

Abstract: A cartridge for use in a spray system, and for releasable connection to a quick-release coupling to form a nozzle assembly. The cartridge includes a generally elongated and hollow body member having a proximal end and a distal end. A nozzle tip is retained at the distal end of the cartridge, and the proximal end is adapted to fit, at least in part, within the quick-release coupling.     The body member,includes a shoulder for retaining the nozzle tip. In a basic embodiment, the cartridge includes a generally hollow tubular spacer which fits, at least partially, inside the body member, for pressing the nozzle tip against a shoulder formed by the body member at the distal end. An O-ring is disposed between the shoulder and the spacer, in order to seal the cartridge and to prevent leakage. A screw fits within the proximal end of the body member for retaining the spacer in tight engagement with the nozzle tip. In other embodiments, the cartridge includes a plurality of components, such as a sequence of filters and a check valve. The basic embodiment of the cartridge is assembled by fitting the O-ring on the nozzle tip; by inserting the nozzle tip inside the body member; by introducing a spacer inside the body member for abutting against the nozzle tip; and by advancing the U-shaped screw within the body member to securely retain the spacer against the nozzle tip.

Filed: 1995-02-21
Granted: 2001-12-04
Abstract: The invention provides a blow molded two liter carbonated beverage bottle (1 ) weighing under 50 grams and having a unique petaloid base (7) and an ability to be self-standing on a support surface. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet 9. Between each adjacent pair of feet is a radially extending valley (12) the width of which decreases with increasing radial distance from the longitudinal axis of the bottle toward a point of convergence (14) radially outside the bottle's diameter. The valley floor generally follows the hemispherical base shape and opens to an extended portion (13) of that base shape lying radially outwardly of the feet. The valley and extended portion, on initial pressurization of the bottle, cause deformation of the extended portions outwardly with a resulting raising of the center of the base away from the support surface.
