Patent CA-2331283-A1 (CA)
Inventor: IWAMOTO JUNICHI
IPC: F01L13/00
Filed: 2001-01-17
Abstract: A valve operating system in an interned combustion engine includes an associative-operation switchover means capable of switching over the associative operation of a pair of rocker arms disposed adjacent each other and the releasing of the associative-operation. The associative-operation switchover means is provided between a plurality of rocker arms including the rocker arms disposed adjacent each other. In such valve operating system, through-bores are coaxially provided in support walls of the rocker arm, and opposite ends of a roller shaft are fitted and fixed in the through-bores. A spring- receiving member is mounted to the roller shaft for receiving a return spring. Thus, when the roller shaft with the return spring of the associative-operation switchover means accommodated therein is mounted to the rocker arm, it is possible to facilitate the processing and to reduce the size and weight of the rocker arm.

Title: Nutritional and therapeutic compositions of 3-hydroxyacids for increasing blood ketone bodies
Inventor: ZHONG LUHUA
IPC: A23L1/30
Filed: 1999-07-22
Abstract: Nutritional or therapeutic compositions are provided for increasing ketone body levels in the blood of mammals by providing a source of ketone bodies in the form of linear or cyclic oligomers and/or derivatives of 3-hydroxyacids. The 3-hydroxyacid can be in the form of a linear oligomer of 3-hydroxyacids other than linear homo-oligomers of 3-hydroxybutyric acid if administered in combination with acetoacetate, cyclic oligomers of 3-hydroxyacids, esters of the linear or cyclic oligomers, esters of 3-hydroxyacids other than 3-hydroxybutyric acid, and combinations thereof. An oligomer generally refers to a polymer of three or more hydroxyacids.  Preferred 3-hydroxyacids include 3-hydroxybutyrate, 3-hydroxy-valerate, 3-hydroxyhexanoate, and 3-hydroxyheptanoate. Oligomers of odd-carbon number 3-hydroxyacids such as 3-hydroxyvalerate have advantages since they have a higher energy content than oligomers of 3-hydroxyacids having an even-number of carbons. The cyclic oligomers have advantageous properties since they result in a sustained, and/or controlled, ketone blood level over a period of hours. The compositions can be administered orally, for example, as a nutritional or dietary supplement, or intravenously.  Increasing blood ketone levels is useful for seizure control, metabolic disease control, reduction of protein catabolism, appetite suppression, parenteral nutrition, increasing cardiac efficiency, treatment of diabetes and insulin resistant states, and treatment of effects of neurodegenerative disorders and epilepsy.

Title: Method and apparatus for assuring sufficient bandwidth of a statistical multiplexer
Inventor: SCHOENBLUM JOEL
IPC: H04J3/06
Filed: 2000-01-27
Abstract: Techniques for determining an output rate for a bit stream, the output rate being determined by applying information read from the bit stream to availab le bandwidths. The techniques are employed to construct a statistical multiplex er that multiplexes varying bit-rate bit streams onto a satellite up-link. Minimum and maximum output rates for each bit stream are determined such tha t neither a queue for the bit stream in the multiplexer nor the bit stream's decoder will underflow or overflow. The multiplexer looks at the fullness of  the memory buffers and correlates the fullness with the likelihood of a condition in which output will exceed bandwidth. If there is not enough bandwidth to give every bit stream its minimum rate, glue frames may be inserted, or low priority channels dropped.

Abstract: A drug delivery molecule has a targeting moiety, coupled to a routing moiety  and a bioactive molecule. The targeting moiety binds to a cell receptor without eliciting an agonistic effect and binding results in uptake of the drug delivery molecule into the cell. Contemplated drug delivery molecules m ay be employed for treatment and diagnosis. A method of selectively targeting a n endothelial cell includes recognizing that presence or absence of somatostat in type II receptors on the endothelial cell correlates with a proximal positio n of the endothelial cell to an anomalous cell. Endothelial cells proximal to anomalous cells are then presented with a somatostatin type II receptor specific compound. In further methods, the presence of a somatostatin type I I receptor on an endothelial cell proximal to a tissue is correlated with a disease of the tissue. In subsequent steps, somatostatin type II receptor specific compounds are administered to the endothelial cell.

Abstract: A method for incorporating concentrated milkfat into milk to form a concentrated milkfat/milk blend is provided. The concentrated milkfat/milk blend can be used in the preparation of natural cheese. The method provides a cost effective procedure for blending concentrated milk fat and milk without the use of added stabilizers. Fat in the concentrated milkfat/milk blend does not separate during additional processing required in producing a natural cheese from the concentrated milkfat/milk blend. In this process, a reduced-fat milk is blended with concentrated milkfat at a temperature sufficient to melt the concentrated milkfat to form a slurry. The slurry is homogenized, preferably using an in-line jet homogenizes at a pressure of about 90 to about 225 psig or a piston type homogenizer operated at a pressure of about 500 to about 1500 psig, to obtain the concentrated milkfat/milk blend with an average fat particle size of about 1.0 to about 10 microns and a fat particle size distribution such that at least about 90 percent of the fat particles have a particle size of about 1.0 to about 10 microns.  The concentrated milkfat/milk blend can be used to prepared natural cheese using conventional cheese-making techniques.

Abstract: The present invention supports a voice messaging service in a wireless communications system. The wireless communications system comprises a serving mobile switching center (MSC), a service control point (SCP), and a voice messaging system (VMS). A subscriber accesses the VMS through a wireless device to retrieve voice messages that are deposited into the subscriber's voice mailbox. When listening to a voice message that is deposited by a call sender, the subscriber may wish to return a call to the call sender. In such a case, the subscriber initiates the call by invoking a call sender option. The call is established to the call sender's directory number through the serving MSC in concert with the SCP. After completing the call to the call sender, the subscriber may return to the VMS and resume the voice mail session at a desired location corresponding with the subscriber's previous interactions with the VMS.
