Patent number: 10691820Abstract: A message distribution system replicates a collection of messages across multiple regional data centers. When any of the data centers receives a message for distribution from an authorized publisher, it transmits the message to each of the other data centers so that the collection of messages is immediately replicated among each data center. When any data center determines that a subscriber is connected to it, that data center determines which messages in the data collection the subscriber is authorized to receive, and it automatically sends those messages to the subscriber.Type: GrantFiled: November 10, 2017Date of Patent: June 23, 2020Assignee: PubNub Inc.Inventors: Stephen Blum, Todd Greene

Patent number: 9955444Abstract: A system synchronizes data across multiple data centers to geographically distributed clients may receive current versions of the objects (or portions of objects) from whatever data center is closest to the client. When one of the data centers receives an application object from a first client, it may save the application object in a data collection at that data center. It may also send the application object to other data centers so that the application object is replicated among each of the other data centers. Each of the data centers will relay the updates to the other data centers subscribing clients via various channels, while at least some of the data centers will make the updates available to clients who request the updates. Optionally, the data centers also may publish change notification messages to the channels.Type: GrantFiled: November 5, 2015Date of Patent: April 24, 2018Assignee: PubNub Inc.Inventors: Stephen Blum, Dara Kong, Aaron Levy, Bhagat Nainani, Jochen Roth, Jason Oster, Geremy Cohen

Publication number: 20030059665Abstract: The aim of the invention is to provide a mechanically stable microreactor that can be subjected to high electrical loads and that is used in an electrode system of a fuel cell. To this end, a fuel component flows towards a filament (98) through at least one flow channel (102). Said filament is configured as a radially inner electroconducting electrode of the microreactor (97) and is linked with a radially outer membrane (101), the two structures supporting one another. The radially inner peripheral surface of the membrane (101), at least in some sections, is spaced apart from a supporting core (55) of the filament (98) by spokes (100), thereby forming at least one flow channel (102).Type: ApplicationFiled: December 3, 2002Publication date: March 27, 2003Inventors: Stephen Blum, Robert Heggemann, Bernd Luhrs

Patent number: 6451856Abstract: The present invention relates to a method of feeding carnitine supplemented diets to sows during the period of gestation or during both gestation and lactation periods. The method enhances pork productivity by increasing litter and pig birth and weaning weights, reducing the number of stillborn pigs and increasing the number of pigs born alive in the subsequent reproductive cycle. Sow diets of this invention include carnitine, such as L-carnitine or L-carnitine salts. Carnitine is generally added to the swine feed formulation in the amount of from about 5 to about 5,000 ppm.Type: GrantFiled: July 18, 2000Date of Patent: September 17, 2002Assignees: Lonza Inc., Kansas State University Research FoundationInventors: Stephen A. Blum, Kevin Q. Owen, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Rene A. Blum, Robert E. Musser

Patent number: 5525350Abstract: Improved animal diets for oral administration are provided which include a quantity of non-hydrolyzed, non-digested, naturally occurring protein supplemented with a minor amount of an additive selected from the group consisting of di- and tripeptides including an essential amino acid residue. The diets commonly include at least about 8% by weight of such intact protein, which may be derived from typical plant or animal sources. The preferred additive includes an essential amino acid residue selected from the group consisting of lysine, methionine, threonine, tryptophan, isoleucine and valine. Use of the di-and tripeptide additives of the invention gives increased nitrogen use by the animal, as compared with feeding of the amino acid constituents of the additives.Type: GrantFiled: September 16, 1994Date of Patent: June 11, 1996Assignees: Kansas State University Research Foundation, Lonza, Inc.Inventors: Jeffrey A. Hansen, Jim L. Nelssen, Stephen A. Blum, Mike D. Tokach, Robert D. Goodband

Patent number: 5192804Abstract: A feed composition containing L-carnitine and a high nutrient density diet is found to increase the lean-to-fat ratio of early weaned pigs. The L-carnitine is preferably reduced as the animal passes through its various stages of development, with initial concentrations ranging from 5 to 5000 ppm. In the finishing stage, less than 5 ppm of L-carnitine may advantageously be incorporated in the diet.Type: GrantFiled: June 22, 1992Date of Patent: March 9, 1993Assignees: Lonza Inc., Kansas State University Research Foundation, University of Georgia ResearchInventors: Stephen A.

Patent number: 5124357Abstract: Feed compositions containing at least 0.6% lysine, preferably between about 0.7 and 0.8% lysine, and between approximately 0.1 to 400 ppm, preferably between 5 and 50 ppm, L-carnitine produce greater weight gains and feed efficiency, and alter fat metabolism, as compared with the same diet in the absence of the carnitine when fed to the finishing pigs. The L-carnitine can also be administered as a feed supplement providing between 0.05 and 15 mg L-carnitine/kg body weight/day, most preferably between 0.1 and 2.0 mg L-carnitine/kg body weight/day. The effect of the carnitine is sex linked, with significantly greater weight gains and feed efficiency observed for gilts than for barrows.Type: GrantFiled: September 26, 1991Date of Patent: June 23, 1992Assignees: University of Georgia Research Foundation, Inc., Lonza Inc.Inventors: G. Larry Newton, Stephen A. Blum, Keith D. Haydon

Patent number: 5030657Abstract: Fish feed compositions supplemented with up to 0.5% L-carnitine, preferably between 0.01% to 0.3% L-carnitine, produce greater growth gains, decreased fat levels in tissues, and increased resistance to stress (ammonia toxicity) in fish, as compared to fish fed the same diet without supplemental carnitine.Type: GrantFiled: October 23, 1989Date of Patent: July 9, 1991Assignees: University of Georgia Research Foundation, Inc., Lonza Inc.Inventors: Gary J. Burtle, G. Larry Newton, Stephen A. Blum
