Title: Support base for gas water heaters
Inventor: LESAGE CLAUDE
IPC: F24H9/06
Filed: 1996-06-20
Abstract: A support base for a gas water heater cylindrical housing is described. The base comprises a circular bottom dish having a flat bottom wall and a circumferential flange. A circumferential rounded edge is provided between the bottom wall and the flange. Air passages are defined about the circumferential flange. A circular housing support bottom wall, of larger diameter, is secured on the circumferential flange and has a central passage formed therein to admit air to a burner chamber supported on the bottom wall and through the air passages of the base wherein air currents are developed to cool the base when the burner is in use. The base therefore provides heat loss and further permits sliding and rolling displacement of the water heater cylindrical housing on a floor surface without damaging the floor surface due to the circumferential rounded edge of the base.

Title: Shaped Charge with Wave Shaping Lens
Inventor: CHAWLA MANMOHAN S
IPC: F42B1/024
Filed: 1996-07-26
Abstract: An improved shaped charge for generating a jet. A lens shaped waveshaper is positioned within the explosive material of a shaped charge to modify the shape of the divergent detonation wave into a planar wave or a converging wave. The waveshaper is formed with a low sound speed material having a high index of refraction. By reshaping the detonation wave, the acceleration of the shaped charge liner is increased, and the penetration depth and hole size of the jet can be increased. The shaped charge operates more efficiently, thereby requiring less explosive material than a conventional shaped charge.

Title: Non-Concentric Oil Separator
Inventor: BOEHDE MICHAEL C
IPC: F25B43/02
Filed: 1995-06-13
Abstract: An oil separator (10) for a refrigeration system (100) employing a screw compressor (108) includes a generally cylindrical, vertically upstanding housing(12) the bottom of which defines an oil sump (16) and the top of which is penetrated by discharge conduit (26) connecting the oil separator (10) to the refrigeration system condenser (102). The centerline (28) of the discharge conduit is parallel to but offset from the centerline (30) of the separator housing so that the discharge conduit (26) is non-concentric with the housing (12). As a result, an enlarged tangential inlet (20) to the interior of the separator is made possible which is unimpeded by the discharge conduit (26). The cross-sectional flow area through which the mixture discharge from the compressor (108) passes prior to entering the separator (10) can therefore likewise be increased. As a result, pressure drop in the refrigerant gas as a result of the oil separationprocess is reduced and overall system efficiency is enhanced while the diameter of the separator housing is minimized.
Patent CA-2191145-A1 (CA)
Title: Pipeline Anchor Apparatus
Inventor: JOHANNESSON NEALE
IPC: F16L1/06
Filed: 1996-11-25
Abstract: A pipeline anchor apparatus  is disclosed.   The pipeline anchor apparatus provides left and right anchor units connected by a tie-down strap made of heavy-duty polyester or nylon webbing.   The strap prevents the pipeline from floating in wet conditions.  By flexibly conforming to the surface of the pipeline, the tie-down strap prevents denting of the pipeline which weakens the pipeline, contributing to pipeline bending.  Each anchor unit provides an helix anchor attached to an anchor rod that is buried deep in the soil.   The anchor rod is connected  to  an extension rod by means  of  a  lower coupling.  A tie-down bracket having a tubular body and a sleeve is carried by the extension rod.  Each end of the  tie-down  strap  is  attached to the  sleeve  of  a tie-down  bracket  of  an  anchor unit.    The  tie-down brackets may pivot about the extension rod to lessen stress as water forces the pipeline upwardly, against the tie-down strap.  The sleeve of the tie-down bracket is radially outwardly from the axis of the tubular body.  As a result, an upward force on the sleeve may force the tie-down  bracket  and  extension  rod  away  from  the pipeline, thereby protecting the pipeline from denting and bending.

Title: Brush seals and combined labyrinth and brush seals for rotary machines
Inventor: CRUM GREGORY ALLAN
IPC: F16J15/32
Filed: 1997-05-22
Abstract: Brush seals are retrofitted into existing turbine labyrinth seal rings to create a fail-safe seal design at locations wherever labyrinth seals are currently used, including interstage shaft seals, rotor end seals, bucket (or blade) tip seals and spill strips. Brush seals, per se, when used in place of labyrinth seals, can result in considerable span reductions of steam turbines, or machines with more turbine stages for a given span. Application to end packings results in the potential elimination of gland sealing/exhauster systems. Brush seal life can be improved by retrofitting brush segments to labyrinth seal segments that are either spring-backed, or use pressure loads to obtain design clearances only after steady state operating conditions are achieved. The brush seals are provided with backing plates shaped like labyrinth teeth, resulting in a fail-safe design. Also, the use of existing labyrinth teeth as bristle backing plates results in a brush seal with diminished susceptibility to hysteresis when compared to conventional brush seal designs. Low friction coatings can also be used to reduce brush seal hysteresis. Incorporation of brush seals in labyrinth seal rings that are either spring--backed or held in place by pressure forces results in extremely low brush seal wear.

Title: Process and article for disinfecting water
Inventor: KIICK-FISCHER KRISTI LYNN
IPC: A61L2/18
Filed: 1995-11-30
Abstract: Disclosed is a process for disinfecting water which provides a visual indication after the disinfection is complete. First, the water to be disinfected is generally simultaneously intermixed with at least three items. The items are: (1) a disinfectant which is adapted to render harmless substantially all pathogens present in the water upon the disinfectant being intermixed with the water for a time period Tk; (2) a colorant; and (3) a material which can remove substantially all of the disinfectant and colorant from the water over a time period Tr, where Tr is greater than Tk. Secondly, the water, disinfectant, colorant and the removing material are allowed to remain intermixed for a time period of Tr or greater. At the end of the time period Tr, substantially all pathogens in the water will be rendered harmless, substantially all of the disinfectant will be removed from the water and substantially all of the colorant will be removed from the water. As a result of the removal of the colorant, the water will become uncolored which will give the consumer a visual indication after the disinfection process is complete and the water is safe to drink. Articles for use in carrying out the process are also disclosed.
