(United States Patent and Trademark Office, 1994-05-24)
Means are provided for supplying a liquid surfactant solution, for supplying a gas under pressure, for mixing the liquid surfactant solution and the pressurized gas to form a liquid coarse dispersion of relatively large ...
Trellis support system
(United States Patent and Trademark Office, 1994-12-20)
A trellis system which can be used with raspberry and other fruit production includes a plurality of structural units (36) which are essentially two dimensional in shape to allow for flat packing and shipping. Trellis wires ...
Non-symmetrical inductive sensors having ferrite coil geometries with different top and base geometries
(United States Patent and Trademark Office, 1994-08-09)
New core geometries to increase the sensing range of proximity transducers in general, and eddy current killed oscillator mode sensors, in particular. A theoretical analysis yields electromagnetic parameters that facilitate ...
Active control of aircraft engine inlet noise using compact sound sources and distributed error sensors
(United States Patent and Trademark Office, 1994-10-11)
An active noise control system using a compact sound source is effective to reduce aircraft engine duct noise. The fan noise from a turbofan engine is controlled using an adaptive filtered-x LMS algorithm. Single multi ...
Water soluble derivatives of taxol
(United States Patent and Trademark Office, 1994-10-04)
Sulfonated 2'-acryloyltaxol and sulfonated 2'-O-acyl acid taxol derivatives are synthesized which have improved water solubility and stability while maintaining bio-activity. In particular, 2'-[(3-sulfo-1-oxopropyl)oxy]taxol ...
Carbonate polymers containing ethenyl aryl moieties
(United States Patent and Trademark Office, 1994-11-08)
There are disclosed carbonate polymers having ethenyl aryl moieties. Such carbonate polymers are prepared from one or more multi-hydric compounds and have an average degree of polymerization of at least about 1 based on ...
Fine powders of ketone-containing aromatic polymers and process of manufacture
(United States Patent and Trademark Office, 1994-10-18)
Fine particles of semi-crystalline ketone-containing aromatic polymers (PEEK, PEKK, etc.) are produced by controlling the rate and conditions of hydrolysis of an amorphous polyarylketimine intermediate. The choice of acid ...
Fused biconical taper fiber optic coupler station and fabrication techniques
(United States Patent and Trademark Office, 1994-08-16)
The fibers are bound together about 1 cm apart. An oxy-propane torch is used to heat the fibers so that they fuse together. At the same time, the two relatively movable translational stages to which the fibers are clamped ...
Method of reducing flow metastability in an ejector nozzle
(United States Patent and Trademark Office, 1994-09-06)
A method of reducing flow metastability in a liquid refrigerant in an ejector nozzle by generating dispersed bubbles in the flow entering the nozzle by first forming relatively large bubbles and then breaking them down ...
