Abstract: A wheel motor disconnect includes a rotatable plate with sized apertures including locking detents. A depressor pin extends perpendicularly from the plate. The apertures are received over shouldered spacers or guides which are connected to the wheel hub. In the drive position, the plate is located at the outermost ends of the spacers, and the pin is offset from the spring-loaded drive shaft to allow the shaft to drivingly engage a reduction gear arrangement. To disconnect the drive, the operator urges the plate axially inwardly against the bias of the drive shaft so that the apertures slide inwardly along the spacers to move the shaft out of driving relationship with the reduction gear arrangement. The operator then rotates the plate in a first direction so smaller apertures move into the shouldered area and prevent the plate from moving axially outwardly. The locking detents prevent rotation of the plate away from the shouldered area until the operator depresses the plate slightly and rotates the plate in the direction opposite the first direction.

Title: Regulating metabolism by modifying the level of trehalose-6-phosphate
Inventor: GODDIJN OSCAR JOHANNES MARIA
IPC: C12N5/06
Filed: 1997-05-02
Granted: 2009-07-21
Abstract: The invention lies in the field of regulation of carbon flow in the metabolism of the cell. It has been found that induction of a change in the intracellular availability of the saccharide trehalose-6-phosphate (T-6-P) induces modifications of the development and/or composition of cells, tissue and organs in vivo. These changes can be induced by introducing or inhibiting the enzymes trehalose phosphate synthase (TPS) which is capable of forming T-6-P and trehalose phosphate phosphatase (TPP) which degrades T-6-P into trehalose. The carbon flow through the glycolysis will be stimulated by a decrease in the intracellular level of T-6-P.

Abstract: The invention relates to a device for applying a filamentous implant by means of a pressure-generating unit which is connected to a housing containing the thread to be implanted. The housing opens out into a channel used for delivering the thread externally.  The pressure generation unit generates a static pressure on a fluid contained inside the device, said fluid pushing the thread to be implanted through the distal narrowed tip of the channel, towards the exterior or into a tissue or a body cavity. The fluid remains inside the device in the course of this process. The distal end of the device can be plugged in order to prevent the fluid from exiting after application of the implant. The application can be stopped once an adequate quantity of the implant material has been implanted by severing the thread in the vicinity of the distal end of the channel or at the proximal end.

Title: Sustained-release liposomal anesthetic compositions
Inventor: KIM SINIL
IPC: A61K31/40
Filed: 1998-09-18
Granted: 2003-09-09
Abstract: The invention provides a method for obtaining local anesthetics encapsulated in liposomes, such as multivesicular liposomes, with high encapsulation efficiency and slow release in vivo. When the encapsulated anesthetic is administered as a single intracutaneous dose, the duration of anesthesia and half-life of the drug at the local injection site is increased as compared t o injection of unencapsulated anesthetic. The maximum tolerated dose of the encapsulated anesthetic is also markedly increased in the liposomal formulation over injection of unencapsulated anesthetic. These results show that the liposomal formulation of local anesthetic is useful for sustained local infiltration and nerve block anesthesia.

Abstract: A Network Call Trace (NCT) method and system enables a call path route to be traced in a telecommunications network. A Type of Digit (TOD) in the Generic Digits Parameter (GDP) for an Integrated Services Digital Network (ISDN) User Part (ISUP) command can be utilized to realize the NCT. A listing of Switch IDs (SIDs) from the originating subscriber's switch to the terminating subscriber's switch is provided so that routing inefficiencies can be discovered. In one embodiment, an Initial Address Message (IAM) is transmitted with a TOD Network Call Trace in the GDP. The NCT includes the SID of the originating switch. Any intermediate switches between the originating switch and the terminating switch likewise append their own SID onto the NCT list of SIDs. Finally, the terminating switch also adds its SID onto the end of the NCT list. This NCT list may then be transmitted and displayed for analysis.  For example, it may be transmitted in a backward message such as address complete message (ACM), answer message (ANM), call progress (CPG), or release (REL) back to the originating switch via the network. Alternatively, the NCT  list may be sent to a Network Management Center.
