Title: Gravity feed fluid dispensing valve
Inventor: DYER JOHN J
IPC: B67D3/00
Filed: 1998-09-10
Abstract: A dispensing valve cap mountable to a bottle is provided with a first valve part having a tubular portion having an air inlet and a fluid outlet spaced apart along a longitudinal axis of the tubular portion to form a constant head valve for dispensing fluid from the bottle.  A second valve part of the valve rotatably mounted to the first valve part includes a tubular portion for simultaneously closing both the air inlet and the fluid outlet of the first valve part when fluid dispensing is not desired. The second valve part further includes an air inlet, and a fluid outlet alignable with the air inlet and fluid outlet of the tubular portion when fluid dispensing is desired. The dispensing valve cap controls fluid flow from the bottle. The bottle with the valve cap is usable with a dispenser assembly for mixing a concentrated fluid from the bottle with a dilutant. A tamper resistant lock prevents undesired rotation of the second valve part relative to the first valve part.  The tamper resistant lock is deactivated upon insertion of the valve cap into the dispenser assembly. An orifice insert member with a predetermined fluid control aperture is positioned in the fluid outlet path to control fluid flow rate through the valve cap.

Abstract: As a negative calcium balance is present in spontaneously hypertensive rats (SHR), we searched for gene(s) involved in this dysregulation. A cDNA library was constructed from the SHR parathyroid gland which is a key regulator of serum ionized calcium. From 7 overlapping DNA fragments, a 1100-by novel cDNA containing an open reading frame of 224 codons was reconstituted. This novel gene, named HCaRG (Hypertension-related, Calcium-regulated Gene), was negatively regulated by extracellular calcium concentration and its basal mRNA levels were higher in hypertensive animals. The deduced protein showed no transmembrane domain, 67% a-helix content, a mutated calcium-binding site (EF-hand motif), 4 putative 'leucine zipper' motifs and a nuclear receptor-binding domain. At the subcellular level, HCaRG had a nuclear localization. We cloned the human homolog of this gene. Sequence comparison revealed 80% homology between rats and humans at the nucleotide and amino acid sequences.  Tissue distribution showed a preponderance in the heart, stomach, jejunum, kidney (tubular fraction), liver and adrenal gland (mainly in the medulla). HCaRG mRNA was significantly more expressed in adult than in fetal organs, and its levels were decreased in tumors and cancerous cell lines. We observed that after 60-min ischemia followed by reperfusion, HCaRG  mRNA declined rapidly in contrast with an increase in c-myc mRNA. Its levels then rose steadily to exceed baseline at 48 h of reperfusion. HEK293 cells stably transfected with HCaRG  exhibited much lower proliferation, as shown by cell count and 3H-thymidine incorporation.  Taken together, our results suggest that HCaRG is a nuclear protein potentially involved in the control of cell proliferation.

Abstract: A method and system of managing calls over a data network (20) includes determining an available bandwidth of the data network (20). After a call request is received for establishing a call between at least two network terminals (14, 16, 30), one or more of a plurality of resource elements are selected in response to the call request based on the bandwidth of the data network (20). The resource elements, which can include codecs (coders/decoders), packet sizes (for carrying audio data), and others, are used in the requested call between the at least two network terminals (14, 16, 30). Further, a plurality of communities (402, 404, 406) may be defined each including one or more terminals. One or more usage threshold values may be assigned to a link or links (430, 432) between communities (402, 404, 406), and a call request is processed based on the one or more usage threshold values.

Title: Method for sorting mailpieces
Inventor: GOTTLIEB ROBERT K
IPC: B07C3/00
Filed: 2000-09-14
Abstract: This invention overcomes the disadvantages of the prior art by providing a method of sorting mailpieces which requires less stopping of the sorting process for bin emptying. The present invention is directed to a mailpiece sorting method which indicates when a bin is partially full to the level of a partially full sensor so that an operator can empty that bin. Additionally, a bin-full calculation is performed for determining if redirection of the mailpieces to an alternate bin is necessary should the operator not empty the bin as directed. If a bin is partially full to the level of the sensor, the process performs an addition of thicknesses of all of the mailpieces which are in the mailpiece delivery system, but not yet delivered to the bin to determine whether those mailpieces would fill the bin. If the bin would be full, it is determined whether an alternate bin is available and, if so, the mailpieces are routed to the alternate bin. If an alternate bin is not available, the sorting system is shut down and the full bin(s) is(are) emptied.

Filed: 2000-05-12
Abstract: A system of establishing a supplemental channel (SCH) to provide burst timing for high-speed data transmission in a mobile communication system. A source base station determines that a traffic burst exists and sends a target base station a burst request message. The burst request message includes forward and reverse burst timing information and channel use time information, which is determined in consideration of a discontinuous transmission (DTX) mode, in order to reserve necessary resources, when a large amount of high rate data is to be transmitted.

Title: Ip multicast services over atm multicast
Inventor: WILHELM DIANA JOAN
IPC: H04L12/56
Filed: 2001-03-08
Abstract: A method and apparatus for reducing bandwidth usage in an ATM switching network by controlling bandwidth used for IP multicasting through the switching network.      Bandwidth usage is controlled by modifying ingress and access modules, such as IP service gateways and access modules that terminate branches of a multicast tree. If a join request is received at an IP service gateway from a sink node served by an access module, the IP service gateway instructs the access module to graft a leaf to the branch to join the sink node to the tree and to merge the multicast packets with other IP packets for the sink node.      Consequently, only one connection carrying the multicast traffic is required between the IP service gateway and the access module. Bandwidth usage in the ATM switching network is thereby controlled, and bandwidth usage in service access trunks connecting the access modules to the ATM switching network is reduced.
