Title: So -flue gas conditioning system
Inventor: WORACEK DAVID L
IPC: B03C3/01
Filed: 1987-12-24
Granted: 1993-04-06
Abstract: Abstract of the Disclosure An  air  pollution  control  system  for  injecting  a conditioning agent into the flue gas of a power generator.  The conditioning  agent  changes  the  resistivity  of  particulate matter in the flue gas, rendering the particulate matter more easily able to accept an electrostatic charge.  Control of the conditioning gas injection rate is monitored by periodically sampling the average input power supplied to the power supplies of  the  electrostatic  flue  gas  conditioning  system.    A proportional-integral controller receives the signal represent-ing the difference between the average input power and a pre-determined threshold signal.   The control signal produced by the proportional integral controller causes incremental changes in the rate at which the conditioning agent, such as SO3, is added to the flue gas.

Patent CA-1300490-C (CA)
Inventor: NEWTON CHARLES L
IPC: F25J1/00
Filed: 1988-02-22
Granted: 1992-05-12
Abstract: ABSTRACT     A closed loop single component, e.g. propane or Freon refrigerant, refrigeration cycle is added to a single or dual mixed refrigerant natural gas liquefaction process to precool the natural gas prior to adsorptive drying.  By means of pressure control, the single component refrigerant temperature can be accurately controlled to ensure against hydrate formation in the natural gas feed and to maximize the precooling of the natural gas feed prior to drying.  The addition of the single component refrigeration cycle overcomes the difficulty of controlling the precooling temperature which occurs when cooling by a multicomponent refrigerant, and thus improves plant reliability and minimizes the equipment sizes associated with the drying operation.

Title: Dynamic light scattering apparatus
Inventor: BROWN ROBERT G W
IPC: G01N15/02
Filed: 1988-03-04
Granted: 1993-04-27
Abstract: ABSTRACT   A dynamic light scattering apparatus comprises a laser optically coupled to a light scattering sample via a first monomode optical fibre and a first lens. The lens produces a beam waist in the sample, and scattered light is collected by a receive lens and a second monomode optical fibre. The second fibre has an end face in the Fourier plane of the receive lens, and defines an aperture matched to a single Airy disc of the lens. The receive fibre accordingly receives a single spatial mode of light scattered from the sample, this mode corresponding to a single plane wave to which many scatterers contribute. The receive fibre also attenuates unwanted spatial modes because of its monomode character. A photodetector detects light transmitted by the receive fibre. The invention produces statistically superior results compared to the prior art, this being manifest in an improvement of between 40% and 170% in the parameter [g(2)(?) - 1] at ? = 0.

Granted: 1993-05-11
Abstract: APPARATUS AND PROCESS FOR COUNTERGRAVITY   CASTING OF METAL WITH AIR EXCLUSION      Abstract of the Disclosure A method and apparatus for countergravity casting of molten metal with exclusion of air in a gas-pervious mold sealed in an evacuable chamber having a free end of a fill pipe for the mold cavities projecting therefrom.  The fill pipe is moved relative to an enclosed crucible containing the molten metal under an air-free atmosphere of inert gas to project the fill pipe free end through an opening in the crucible enclosure to a position below the molten metal so that evacuation of the chamber produces filling of the mold. Entry of air into the crucible enclosure through its opening is prevented by maintaining the surface of the molten metal and the ambient atmosphere a sufficient distance apart prior to insertion of the fill pipe to prevent circulating air currents from drawing air through the opening down to the metal.  Entry of air can be further prevented by maintaining  a sufficient pressure of inert gas in the crucible enclosure and by sealing the upper portion of the fill pipe between the chamber and the mold.

Title: Cellulose acetate butyrate gas separation membranes
Inventor: MINHAS BHUPENDER S
IPC: B01D71/12
Filed: 1988-10-18
Granted: 1993-05-11
Abstract: ABSTRACT      Cellulose acetate butyrate gas separation membranes are prepared from a casting solution containing from about 10 to 30 percent polymer, 35 to 70 percent solvent, and 15 to 30 percent pore-forming agents.  A film casting solution is cast onto a substantially flat support surface and a dense layer is formed on the exposed film surface.  The film is gelled, washed, and dried to produce a particularly useful gas separation membrane.  The cellulose acetate polymers used in this preparation have molecular weights of at least about 20,000, and have about 10 to about 45% butyryl groups, about 2 to about 35% acetyl groups, and about 0.8 to about 2 percent hydroxyl groups, by weight.  The membranes may be used for separating a feed gas into a permeate fraction and a residual fraction, and are particularly useful for separating gases in the purge gas stream of ammonia plants to recover a permeate which is relatively rich in hydrogen.  Cellulose acetate butyrate membranes may be used to improve the separation of ammonia plant purge gases which contain ammonia as well as hydrogen and nitrogen, especially when there is no pretreatment of the purge gas to remove ammonia gas.
