Abstract: VALVE ACTUATOR                        Abstract of the Disclosure A valve actuator is capable of being mounted on a valve in alignment with a valve stem which can be moved to open and close the valve.  The actuator includes a hydraulic cylinder and a piston slidably mounted within the cylinder.  A piston rod is joined at a first side of the piston and extends outwardly of the cylinder toward the valve to be joined to the valve stem.  A high pressure gas accumulator is mounted on the cylinder and includes a generally spherical shaped pressure wall which is intersected by the cylinder to locate an end of the cylinder within the accumulator to allow communication of the interior of the accumulator with a second side of the piston.  Hydraulic oil acting on the first side of the piston opens the valve against high pressure gas within the accumulator and evacuation of the hydraulic oil allows the high pressure gas to act on the second side of the piston to rapidly close the valve.

Abstract: Emile B. Steyns Jerry H. Miller By Thomas W. Brennan TITLE: HAND OPERATED SPRAYER WITH AUTOMATIC CONTAINER VENT     ABSTRACT OF THE INVENTION: The problem of venting the interior of a liquid container utilizing an attached hand-operated, trigger sprayer of the piston or plunger pump type is solved by the provision of a vent passage in the housing of the pump which communicates with the container interior. The piston which is reciprocated in a bore or chamber in the housing has a seal means associated therewith and with the vent passage so that in operation in spraying the container is vented and vacuum development in the container is avoided. In a preferred embodiment said seal means is associated with an entrance or opening to the vent passage so as to provide a seal against liquid leakage from the container when the piston of the pump is in an at rest, non-pumping position and yet permits, venting of the container when the piston is in a pumping position.

Abstract: Abstract of the Disclosure Thermally induced porosity, which can lead to cracking in metal powders after consolidation, is believed to be caused by the entrapment of the inert gas used for atomization within the metal powders.  The addition of an activating agent to the molten alloy prior to atomization with an inert gas, such as argon, serves to substantially reduce the porosity of metal powders.  Suitable activating agents are characterized by an ability to rapidly diffuse to the surface of a molten metal particle and an affinity for oxygen.  Activating agents that are useful for high nickel alloys and highly alloyed steels include magnesium, calcium, lithium, silicon, and rare earths.

Abstract: Abstract of the Disclosure Method and means for transferring knit loops from single-hook needles on one cylinder to single-hook needles on the other cylinder of a double cylinder circular knitting machine.  In the method the needles are displaced at an in-clination outwardly of their cylinders to allow axial sliding of the opposing needles behind the inclined needles and into the loops held on the inclined needles; the inclined needles are then withdrawn to shed the hooks, which are then re-ceived on the hooks of the other needles.  The means includes radial pins slidably carried in the cylinders for engagement and operation by stationary radial cams located within the cylinders, the pins extending through the cylinders and into engagement with the stems of the needles for radially dis-placing the needles outwardly to the inclined positions re-quired by the described method.

Abstract: ABSTRACT A closed smoke generating apparatus isolated from the atmosphere is provided in which carrier gases are introduced into a smoke collection chamber, mixed with smoke supplied from a separate distillation chamber mounted therebelow.  Smoke and carrier gases discharged through an outlet can be supplied directly into an associated closed air food processing system.  Wood sawdust or other organic par-ticulate materials are continuously fed into the elongated distillation chamber and are carried by rotating auger.  A heat source surrounds the distillation chamber for destructive distillation of the particulate materials without introduction of air into or leakage of air from the distillation chamber. A residue discharge is provided with means to seal the outlet end of the distillation chamber.  Smoke ports provide direct communication between the distillation chamber and the smoke collection chamber.  Auxiliary heating means can be provided for the smoke ports to reduce deposition of distillation by-products. Further aixiliary heating means can be provided in the collection chamber to minimize deposition of unwanted distillation by-prod-ucts and also to accelerate flow of smoke and carrier gases through the apparatus.  The collection chamber can be of varying size or cross-sectional configuration without requiring a change in the construction of the lower distillation chamber.  The col-lection chamber has a door providing access to the chamber and the smoke ports for cleaning and maintenance.  A layer of insula-tion substantially encloses the distillation chamber, and a separate insulation lay can surround the cmoke collection chamber.

Abstract: METHOD AND APPARATUS FOR ACCUMULATING FUEL PARTICLES IN A PORTION OF A COMBUSTION CHAMBER                   ABSTRACT OF THE DISCLOSURE An improved method and apparatus for effecting the ignition of a relatively lean air-fuel mixture includes a pair of electrode gaps at which strong electrostatic fields of relatively long duration are established to accumulate fuel particles in a portion of a combustion chamber adjacent to a spark gap.  In one embodiment of the invention, one of the electrode gaps is enclosed so that the atmosphere in this gap is not affected by changes in the pressure and composition of the atmosphere in the combustion chamber.  By maintaining the atmosphere in the electrode gap separate from the atmosphere in the combustion chamber, an electrostatic field of substantially constant strength can be maintained at the enclosed electrode gap after the establishment of a corona discharge at an electrode gap exposed to the atmosphere in the combustion chamber.  In another embodiment of the invention, both of the electrode gaps are exposed to the atmosphere in the combustion chamber.  This embodiment of the invention enables strong electrostatic fields and corona discharges of relatively long duration to be established by providing a secondary or floating electrode which is electrically insulated from both a main electrode surface and a third or tertiary electrode surface.

Abstract: CAPSULE MANUFACTURE                    Abstract of the Disclosure A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material.  The polymerization includes a reaction between urea and formaldehyde or polycondensation of monomeric or low molecular weight polymers of dimethylol urea or methylated dimethylol urea in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydro-carbon polyelectrolyte material dissolved in the vehicle.  Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the resulting condensation polymer with-out further dilution of the manufacturing vehicle.  The negatively-charged polyelectrolyte material is required and has an apparent effect of controlling or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of micro-capsules in concentrations of capsule to capsule manufacturing vehicle higher than previously possible.
