Title: Apparatus and methods for reducing fuel/air concentration oscillations in gas turbine combustors
Inventor: BLACK STEPHEN H
IPC: F23D14/02
Filed: 1993-04-08
Abstract: A lean burn gas turbine combustor has a premixer zone receiving compressor discharge air through openings in a combustor liner. A fuel nozzle has an upstream orifice 52, a downstream orifice 56, and a captured response volume 54 therebetween. Upstream orifice 52 affords a high pressure drop for gaseous fuel to approximately the pressure of the compressor discharge air. The low pressure discharge orifice affords a pressure drop comparable to the pressure drop across the openings of the combustor liner for the air supply. The dynamic pressure response characteristics of the fuel and air inlets to the premixer zone are substantially matched to eliminate variations in fuel/air concentration resulting from pressure variations in the premixer zone. The captured response volume between the upstream and downstream orifices is sized sufficiently to store enough fuel to accommodate the mismatch in phase angle of fuel flowing into the captured response volume through the upstream orifice at a first phase angle relative to the phase angle of a pressure forcing function in the premixer zone and fuel flowing out of the captured response volume through the downstream fuel discharge orifice at a second phase angle relative to the phase angle of the pressure forcing function.

Title: Formulations of plant culture media and applications therefor
Inventor: TEASDALE ROBERT D
IPC: A01H4/00
Filed: 1991-11-04
Abstract: An aqueous medium for plant tissue culture is provided including a nutritively effective concentration of reduced nitrogen, preferably in the form of an amino acid such as arginine employed in an amount of from 1.0 to 5.0 mM, and having not more that 1.5 mM  NH4+. A phosphorus compound at a concentration of at least 2.5 mM measured as phosphate is also included. A chelating agent such as EDTA, and an iron compound present in molar excess over the concentration of the chelating agent are employed to control divalent ion concentrations. Potassium ions are maintained at a concentration of below 14 mM. The use of media containing ammonium ions at less than 1.5 mM combined with a supply of reduced nitrogen in the form of arginine, with low potassium levels, has proved useful as media for organized growth, particularly for use with coniferous plants.

IPC: A46B11/00
Filed: 1993-08-17
Abstract: A COMBINATION OF TOOTHBRUSH  AND TOOTHPASTE DISPENSER     ABSTRACT. The present invention relates to a portable dental care combination comprising a toothbrush head and a toothpaste dispenser. The toothbrush head (1) is removable and replaceable, it connects to a handle through a neck elongation (8). The cavity within the handle defines a pressure chamber (P) containing a flexible collapsible cartridge (3), the cartridge holds the toothpaste. The end of the handle is attached to a push-button air pump (5) that forces equal volumes of pressurized air into said pressure chamber (P). The cartridge under a positive pressure in the pressure chamber collapses forcing the toothpaste into a channel within the neck elongation to a dispensing valve (4) thence to the toothbrush head to be delivered to the base of the bristles through a slot.  Upon full collapse of the cartridge and complete depletion of the toothpaste, further pressure build up in the chamber will vent to the outside through relief valve (6) following passage (N) indicating the need to refill the cartridge with fresh toothpaste, or as an alternative purchase a new one.

Title: Dual interferometer spectroscopic imaging system
Inventor: DUMOULIN CHARLES L
IPC: G01N21/17
Filed: 1993-10-14
Abstract: DUAL INTERFEROMETER SPECTROSCOPIC IMAGING SYSTEM                   ABSTRACT OF THE DISCLOSURE    To obtain spectra from the surface of a sample, a first of a pair of interferometers includes a broadband radiation source and modulates the radiation at a frequency which is inversely proportional to wavelength. The modulated radiation impinges on the surface of interest where it is absorbed. The absorption of radiation causes the surface of the sample to expand. This change in dimension is then detected by a second interferometer which employs a monochromatic radiation source to measure the instantaneous distance between the sample surface and the second interferometer. The detection system of the second interferometer can be an imaging device such as a video camera to obtain the spatial distribution of chemical composition of the sample surface.

Abstract: A composite mold that facilitates the fabrication, in a single curing step, of composite articles having opposing sets of stif-fening members disposed in combination with a main structural panel. The composite mold provides for simultaneous co-curing of the opposed stiffening members in combination with the main structural panel. The composite mold includes a rigid mold as-sembly and a "T" mold assembly, which, in combination, define a rigid lay-up surface for the prepreg laminates forming the main structural panel. The rigid mold assembly includes rigid members that act as reactive surfaces for cure pressures, and rem-ovable end and wedge members for assembling/disassembling of the rigid mold assembly, "T" mold assembly combination. The "T" mold assembly is operative during the cure process to generate the pressure required to cure the legs of one set of the stiffen-ing members. The "T" mold assembly includes complementary first and second pressure blocks that define the configuration of the one set of stiffening members. At least one of the complementary pressure blocks has a thermally expansible material encap-sulated therein that is operative, in response to elevated temperatures experienced during the cure process, to expand, causing the complementary pressure blocks to exert the pressure necessary to cure the legs of the one set of the stiffening members.
