Abstract: A low NOx burner combustion system (10) which may be adjusted for optimum burn rates, temperature and oxygen levels. The burner (10) incorpo-rates a plurality of gas nozzles (38) which individually inspirate a portion of the combustion air and a spin vane dif-fuser (28) to rotate and mix the gases within the primary combustion zone (24). The diffuser (28) is axially adjus-table in order to vary the distance be-tween the vane and the first combustion zone (24) while the blades (30) of the diffuser (28) can be angularly adjusted to optimize the rotation and mix of the gases. Air for combustion is supplied through primary (20), secondary (42) and tertiary (54) passages to create dis-tinct combustion zones for complete combustion. The flow rate of the com-bustion air is controlled through a dam-per (26) in accordance with the burn characteristics. The angular and axial position of the diffuser and the damper control of combustion air can be auto-matically adjusted throughout the firing range of the burner (10) in response to demand levels. In order to convert existing burners to the efficient low NOx burner of the present invention the primary air chamber may be retrofit into the main burn-er chamber. In a further embodiment, flue gas is recirculated and mixed directly with combustion fuel prior to combustion for reduced emission levels.

Title: Phacoemulsification probe circuit with switch drive means
Inventor: KEPLEY KEVIN PAUL
IPC: A61F9/007
Filed: 1993-09-02
Granted: 2003-04-29
Abstract: A drive for a phacoemulsification probe includes a drive circuit for supplying electrical power to the probe, circuitry for sensing the electrical power supplied by the drive circuit to the probe and for supplying electrical signals indicative of the magnitude of the electrical power supplied. A manually operable input device provides a signal indicative of the transducer power level desired by the user of the probe. A control circuit is responsive to the signal indicative of the desired transducer power level and to the signals indicative of the magnitude of the supplied electrical power for providing control signals to the drive circuit to control the power applied in an efficient manner. The drive circuit includes a totem-pale switch, responsive to at least one of the control signals, to apply power in a square-wave waveform, and a switching regulator for supplying a supply voltage to the totem-pole switch. The totem-pole switch has circuitry associated therewith which is responsive to one of the control signals to initially vary the frequency of the square-wave waveform. The regulator is responsive to a second control signal from the control circuit to vary the voltage supplied by the regulator to the totem-pole switch to control the amplitude of the square-wave waveform. The switching nature of this system substantially minimizes the power consumption of the drive circuit as compared with conventional techniques.

Abstract: Cultures of keratinocyte cells are provided which are free from nonautologous fibroblasts and organ extracts, and which have a high speed of cell amplification for a minimum seeding density. Preferably, a culture contains no more than about 10% autologous non-keratinocyte cells such as star--shaped, non-keratinocyte cells and no more than about 1%  autologous fibroblasts. The cultures can be cryopreserved in a buffered isotonic medium containing serum and a cryoprotectant.  The cultures are produced by a process that does not involve the use of a feeder layer and organ extracts. A culture medium used contains Medium 199, serum, epidermal growth factor, cholera toxin and/or hydrocortisone, and optionally insulin. A  substance for wound healing and for cosmetic applications is derived from cultured human keratinocytes. Lyophilized keratinocyte cell cultures or an extract therefrom is used to provide a pharmaceutical composition. Confluent and cohesive keratinocyte sheets are prepared for use in wound healing. A  non-viable total keratinocyte lysate for use in promoting wound healing is produced by growing keratinocyte cells on a support, detaching the cells from the support, and lysing the detached cells to obtain the lysate. The lysate may be frozen and lyophilized. The detached cells may be frozen to produce the lysate without lysis before freezing.

Title: Spacer for an insulated window panel assembly
Inventor: REEVES MYRON D
IPC: E06B3/673
Filed: 1996-02-14
Granted: 2000-05-02
Abstract: An insulated window panel assembly for use in window and door assemblies hav-ing an improved insulating spacer between the window panes comprising the panel assembly. At least two panes of glass or other panel material are interconnected in parallel, spaced relationship by a spacer assembly. The spacer assembly is preferably a single length of tubing, generally rectangular in shape, having an outer wall of a first width interconnected to an inner wall of less width by generally concave sidewalls. The sidewalls also contain a bead of sealer material configured to seal with the adjacent window panes. A secondary seal is deposited on the outer wall and overlaps the sidewalls to also form a seal with the window panes. The spacer assembly is preferably one piece, bent to conform to the overall shape of the window panes wherein a first end of the spacer is connected to the opposite end. Folds may be made in the spacer along a crimp line formed in the inner wall to accommodate angular window pane configurations. Folding of the spacer about the crimp line deforms the sidewalls and a fraction of the inner and outer walls inwardly in order to prevent a width increase of any wall which may produce a point with the adjoining window pane.
