US Patent:

40946460, Jun 13, 1978

Filed:

Jun 2, 1977

Appl. No.:

5/802600

Inventors:

David L. Stern - Baltimore MD
Daniel B. Samchuck - Towson MD

Assignee:

The Baltimore Spice Company - Baltimore MD

International Classification:

G01N 2124
G01N 3316

US Classification:

23230R

Abstract:

A rapid method for assaying collagen in meat and meat products. A sample of the material being tested is subjected to a controlled, incomplete hydrolysis of the amino acids with an acidified solution of stannous chloride in such a way that all of the tryptophan is completely destroyed but only a portion of the hydroxyproline is hydrolyzed. The percent collagen is correlated with the percent hydroxyproline, colorimetrically determined.

Appl. No.:

5/802601

Inventors:

David L. Stern - Baltimore MD

Assignee:

The Baltimore Spice Company - Baltimore MD

International Classification:

G01J 350

US Classification:

356411

Abstract:

An improved Colorimeter which can be used to analyze samples in either a stationary mode (e. g. in a test tube) or in a flow-through mode wherein the sample flows through the apparatus. The Colorimeter is equipped with means to direct the illuminating radiation selectively to either mode of sample.

International Classification:

H04N 21/647
G06F 16/735
H04N 21/454
H04N 21/4545

Abstract:

A system and method of conserving network bandwidth by controlling access to resources. A filtering service determines if a resource should be blocked or allowed to pass between computers on the network based on information about the resource including the path and any query parameters in the URI along with any available metadata about the resource. The metadata may be retrieved from the remote hose, generated based on the content of the resource, or any combination thereof. One or more filtering algorithms may be engaged to compare the information about the resource to filtering rules to determine whether access to the resource is allowed. The information about the resource, and the result of the filtering algorithm may be stored to reduce the time required to make future determinations for the same resource, or for similar resources.

International Classification:

Abstract:

Systems and methods are provided to ensure lossless and ordered traversal of digital information destined for and generated from a plurality of live compute assets during the relocation of a plurality of live compute assets from one network enabled computer to a plurality of network enabled computers. After the storage of digital information is initiated through the controlled devices, the live compute assets are relocated to the new computer(s). Simultaneously, or following the relocation of the computer assets, the digital information temporarily stored within the network may be moved and stored subsequently within the network to optimize the reliable delivery through software control of the physical and virtual network/network enabled devices. Upon completion of the relocation of the live compute assets, software is utilized to complete network traversal of new and temporarily stored digital information through the network to/from the relocated compute assets in an ordered, lossless, and reliable manner.
