Publication number: 20030022358Abstract: Provided are membrane filters and methods of trapping, and culturing microorganisms. The membrane filters trap or filter from a sample a specific microorganism of interest requiring a set of growth components. The membrane comprises a first subset of the set of growth components such that the microorganism can grow and divide with the membrane contacting a medium comprising a second subset of the set of growth components defined as all components of the set of growth components not included in the first subset. Methods for detecting a microorganism comprise: (i) providing a membrane filter, comprising a first subset of the set of growth components; (ii) filtering a sample through the filter; and (iii) placing the filter in contact with a medium comprising a second subset of the set of components for growth. For members of genus Legionella a filter impregnated with activated charcoal may be employed for detection and culturing.Type: ApplicationFiled: May 24, 2002Publication date: January 30, 2003Inventors: Jane H.

Patent number: 5661029Abstract: A biological culture growth and observation system provides for the growth of a biological sample in a growth medium, and the observation of the grown sample (organism) through a microscope objective once growth is sufficient as to permit discrimination of the biological sample. Observation and growth is achieved in a single device. The system includes a tray with a top, and a sealable section on the top. Included within the tray is a depression, or well, that receives the growth medium to grow the biological organism in the well. A lid is sealable and resealable around the sealable section on the top of the tray. An interior side of the lid, that faces the growth medium, does not fog up in the presence of the growth medium. Optionally included is a barrier layer that is positioned over the well. The barrier layer minimizes evaporation from the growth medium and permits the biological culture growth and observation system to have a long shelf life.Type: GrantFiled: May 12, 1994Date of Patent: August 26, 1997Assignee: BiomedInventors: Jim Self, Robert D.

Patent number: 5578878Abstract: An armature assembly 50 for an electric motor 10 is inherently balanced despite the presence of a secondary shaft 74 extending from a primary armature shaft 72 longitudinally along an eccentric axis 75 offset radially from the longitudinal axis 15 of the primary armature shaft 72. A lamination stack 60 mounted on the armature shaft 70 is formed of a plurality of lamination plates 62 arrayed in abutting face-to-face relationship. The lamination plates 62B and 62C provided at the respective ends of the stack 60 are modified in that some of the radially directed spokes 66 are removed along a selected portion or spaced portions 63,67 of the circumferential extent of the hub portion 64 so as to provide counterweight lamination plates having a spoke pattern which is not symmetric about the longitudinal axis 15 of the primary shaft 72.Type: GrantFiled: August 30, 1994Date of Patent: November 26, 1996Assignee: United Technologies Motor Systems, Inc.Inventor: Robert D.

Patent number: 5358542Abstract: A cooling system for neck ring molds in a glass molding machine having retractable parison-forming molds engageable with the neck rings employs air jets directed at exposed portions of the neck ring molds. The neck ring molds are configured to extend out of the bottom of the main parison mold and to engage with neck ring hangers. The neck ring molds are configured sufficiently long that a space is created between the bottoms of the main parison molds and the hangers to permit direct access to portions of the neck ring mold. Air supplied in the form of air jets from a pair of cooling air plenums is directed at the exposed portions of the neck ring molds to provide cooling.Type: GrantFiled: December 9, 1992Date of Patent: October 25, 1994Assignee: American National Can CompanyInventors: Robert S.

Patent number: 4731554Abstract: A low profile ring-shaped motor has a housing, a bearing support attached to the housing and supporting a rotating shaft carrying a ring-shaped rotor. A ring-shaped stator is secured to the housing and is concentric and between the legs of the U-shaped rotor. The stator is formed by a continuous strip of magnetic material wound and laminated in a toroid and having helical windings therearound. On the inside of the legs of the rotor are mounted a plurality of permanent magnets forming the poles of the motor. Radially opposite magnets are of the same polarity. Control of the switching of the current through the windings is by means of Hall Effect devices sensing the change in polarity of a ring shaped magnet means having the same number of poles as does the permanent magnets.Type: GrantFiled: November 14, 1985Date of Patent: March 15, 1988Assignee: Allied CorporationInventors: Robert D.

Patent number: 4421629Abstract: A delayed coking and dedusting process in which dust laden heavy oil derived from solid hydrocarbon-containing material, such as oil shale, coal or tar sand, is preheated in a furnace and thermal cracked in a retort to yield light oils and middle oils. Preferably, steam is injected into the dust laden heavy oil before the dusty oil is heated in the furnace to minimize coking in furnace tubes and furnace outlet lines. The thermal cracked dusty oil leaves a residual dust enriched, coked material that can be combusted to provide a portion of the solid heat carrier material for use in retorting oil shale, coal or tar sand.Type: GrantFiled: June 8, 1981Date of Patent: December 20, 1983Assignee: Standard Oil Company (Indiana)Inventors: Earl D.
