Title: Method and apparatus for storing and dispensing liquid
Inventor: LOMBARDO SAMUEL N
IPC: B67D1/14
Filed: 1993-03-22
Abstract: Carbonated and non-carbonated beverages are dispensed under the force of a one time charge of pressurized inert gas inserted into the headspace of the container at the time of bottling/canning.

Inventor: HUMPHREYS REGINALD D
IPC: B03B9/02
Filed: 1994-11-04
Abstract: A hot water extraction process for extracting bitumen from tar sands is taught using a conditioning agent containing sodium and/or potassium bicarbonate or, alternatively, sodium bicarbonate and/or potassium bicarbonate and sources of calcium ions and/or magnesium ions. The conditioning agent replaces the caustic soda agent previously used in tar sand extraction. The use of the alkali metal bicarbonate solvent substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning agent solution to be recycled to the process.

Inventor: MURDOCK NOLAN J
IPC: F21V9/40
Filed: 1995-03-24
Abstract: ABSTRACT         A lighting system and method with variable light intensity for use in motion picture photography.  In the lighting apparatus, light emitted from a source (18) is passed through  an aperture  (36a)  and then through  a section of a movable, neutral density filter (50).  The preferred filter is specially designed to have a variable density,  continuously increasing from one side of the filter to the other.   By changing the position of the filter,  selectively  placing  higher  or  lower  density sections in the light path, the intensity of the light emitted by the lighting apparatus may be varied.   The neutral density filter is selected to be generally color neutral so that the color quality of the light passing therethrough remains unchanged.  To ensure complete light blockage, a douser (80)  of opaque material is provided which is selectively interposed in the outgoing light path.

Filed: 1995-04-24
Abstract: A sampling device is provided which, in one embodiment, includes a hinged body member. The hinged body member may be connected to a similarly configured non-movable body member, the body members forming a hollow sampling cylinder. The provision of a hinged body member provides easy access to the sample and therefor permits the user to remove the sample in an intact and consolidated form. A second embodiment provides for a pair of mutually pivotable body members to provide quick access to the sample core. In a further embodiment, a hollow sample cylinder may be disposed within the movable members to retain the sample. The result is a sampling device which overcomes the limitations in the prior art by allowing the user to sample material to be sampled without disrupting or otherwise affecting the sampled material integrity.
