Appl. No.:

13/796848

Inventors:

Peter W. Latham - Acton MA, US

Robert Sever - Arlington Heights IL, US

International Classification:

A61L 2/00

US Classification:

422 33, 422255

Abstract:

Methods and systems for virus inactivation in the production or processing of biological or other sensitive substances are provided. The disclosed methods and systems for virus inactivation involve the key steps of dissolving carbon dioxide into biological or other sensitive substances; and treating the substance with the dissolved carbon dioxide at conditions which are less than critical pressure and temperature for a prescribed treatment time to inactivate at least 80% of the target virus or viruses contained within the biological or other sensitive substances. The disclosed carbon dioxide treatments for virus inactivation may optionally include concurrently or sequentially subjecting the substances with an acid treatment to lower the pH of the substance and inactivate viruses contained within the biological or other sensitive substance. Operating conditions for the disclosed carbon dioxide treatments preferably involve sparging carbon dioxide gas into the substance until the composition is saturated with carbon dioxide and is conducted at pressures below about 5 MPa; at temperatures of less than or equal to 30 C.; and for a treatment time of between about one minute and about 2000 minutes.

International Classification:

B65B 3900

US Classification:

53473

Abstract:

A method and device for assisting a user with transferring an object supported by the device into a flexible storage container, the device comprising a substantially flat base member having a pair of opposed side edges and a pair of opposed end edges, a side wall extending substantially perpendicular from one surface of the base member along each of the two opposed side edges, and a protrusion member projecting substantially normal from the opposite surface of the base member, for providing a pivot about which the device can pivot, the protrusion member being positioned substantially along a traversed axis of the device and being spaced from each of the opposed end edges so that when the device is placed upon a flat support surface and the protrusion member engages that support surface, the device is pivotable about the protrusion member whereby only one end edge of the base member is able to contact that support surface at any given time thereby facilitating engagement with a storage container and transfer of an object.

US Classification:

222207

Abstract:

A dispenser for a viscous substance includes a disposable plastic container for the substance and a pump permanently unreleasably mounted to the top of the container for pumping the substance from the container. The pump includes a housing communicating with the interior of the container and a pumping assembly including a movable housing wall and a tubular member connected to the wall and being movable along a motion axis between extended and retracted positions relative to the housing. An actuator is provided for the pump which includes a support member removably mounted to the cartridge, a target member movably mounted to the support member and linkage for releasably linking the target member to the tubular member so that when the target member is moved in one direction, the pumping assembly is moved to its extended position in the housing and when the target member is moved in another direction, the pumping assembly is moved to its retracted position in the housing. Preferably, the connection between the tubular member and the movable housing wall is a lost-motion connection.

Abstract:

A bird feeding device is provided with a perch which can be adjustably positioned with respect to the feeding opening to selectively accommodate different sizes of birds. The perch is movable toward and away from the feeding opening so that for larger birds the perch is positioned farther from the feeding opening than for smaller birds. The disclosed embodiment also includes a simultaneous heightwise adjustment for the position of the perch so that it is lowered when in its more extended position. Also disclosed is an improved arrangement for attaching the perch and feeding device to the container of the bird feeder. Another aspect of the invention relates to a bird feeder having a storage and feeding tube which is detachably connected to an overhead support by a quick disconnect device which provides for quick and simplified filling of the feed tubes as well as an arrangement which minimizes spilling or loss of bird seed.

Inventors:

Peter A. Latham - Boston MA

International Classification:

B65D 572

US Classification:

222491

Abstract:

The present invention is a discharge nozzle for flexible dispensing tubes containing paste-like or semi-liquid substances. It solves the problem of having to contact the discharge opening of the dispensing tube against a secondary surface to cut off the flow of substance. This is advantageous for eliminating the transfer of germs between the discharge opening of the dispensing tube and the secondary surface. Additionally, it solves the problem of eliminating unwanted accumulation of substance at the nozzle discharge, even when the dispensing tube is used in a repetitive manner, over a long period of time. The nozzle is small in size, has a symmetrical interior surface, and has a discharge portion formed at least partially from a material possessing a low coefficient of friction. This discharge portion has an elongated slit and is attached to a tubular neck. The elongated slit may be configured in the shape of an "I" to form two displaceable tongues.

International Classification:

F16K 3118

US Classification:

1371702

Abstract:

A beer foam reducing apparatus disposed for placement into the beer delivery lines between a keg and a beer serving spout to prevent pressurized carbon dioxide from entering the delivery line between the apparatus and the serving spout when a keg empties of beer. The apparatus comprises a base with a shallow receptacle disposed to receive an inverted, clear plastic container for sealed, threaded engagement. The plastic container is easily removed for cleaning or replacement and easily sealed for operation. The apparatus also comprises an inlet and outlet in the base, a float disposed for releasably sealing the outlet of the base when a keg empties, and a flow control column secured in the base and extending upwards into the inverted container. Single handed manipulation of a handle leveraged against a mounting bracket regulates operation of the flow control column, and specifically the venting of pressurized carbon dioxide and releasing of the float to begin delivery of beer through the outlet.
