Patent CA-2174705-A1 (CA)
Inventor: EVA W ALLAN III
IPC: B63B3/08
Filed: 1996-04-22
Abstract: A floating, drive-on dry dock assembly for a small craft is assembled from two kinds of hollow floatation units, tall units and short units. The units are interconnected so that their top surfaces are substantially coplanar. The units are arranged to form two arms which support the hull of the craft on each side of the longitudinal center line of the craft. The entire length of each arm is made up of tall units except the distal end portions of each arm which may be made up of short units. The short units are able to flex downward as a craft begins to ride up on the dock because of the location of the connection between adjacent units. The tall units, however, cannot flex relative to each other nearly to the same extent as the short units, and so they form a stable generally planar surface. The distal ends of the arms are connected to each other by an upside down short unit. The short units are proportioned so that the uppermost surface of each is out of the water both when the dock is empty and when a craft is "parked" on the dock.

IPC: F16K17/38
Filed: 1996-07-08
Abstract: A shutoff valve for closing off flow through a fluid line includes a stem 28 axially movable relative to a valve body 12. A valve element 22 is carried by the stem 28 for engagement with a seat 20 to close off fluid flow through the valve, and is biased toward the seat by valve closure spring 40. The swivel body 52 is pivotally connected to the upper end of the stem, and may be rotated to allow the spring 40 to force the valve element into engagement with the seat. A fusible link mechanism 64 is carried by the swivel body for engagement with the valve body to rotate the swivel body to the valved closed position. The mechanism 64 includes a piston 66, a spring 70, and a fusible material for normally acting as a solid stop to prevent the spring 70 from moving piston 66 to rotate the swivel body to the valve closed position. According to the method of the invention, the solid state of the fusible material is altered when the valve is subjected to an elevated temperature, thereby allowing the spring 70 to move the piston 66 to automatically rotate the swivel body and close the valve.

Title: Pharmaceutical compositions based on aminomethylindoles and their therapeutical application as neuroprotectors in parkinson and alzheimer diseases
Inventor: CONTELLES JOSE LUIS MARCO
IPC: A61K31/40
Filed: 1996-02-08
Abstract: Pharmaceutical compositions containing active ingredients derived from 2-aminomethyl-5-benzyloxyindols, including their N-propinyl, N-2-butinyl- and N-2,3-butadienil derivatives, which are potent inhibitors of monoamine oxidase types A and B in rat liver and brain, as well as in human brain, with a marked selectivity for the inhibition "in vitro" and "in vivo" of monoamine oxidase B in preference to A.          Based on this selectivity for inhibition of monoamine oxidase B, as well as the capacity to neutralise the neurotoxic action of MPTP and other neurotoxins in laboratory animals, the above compounds are useful for the treatment of cerebral neurodegenerative processes and in particular for the treatment of Parkinsonism and Alzheimer's disease.

IPC: H04M3/00
Filed: 1996-10-31
Abstract: Embedding one or a plurality of wireless switches into a switching system. The wireless switches are both physically and logically integrated into the switching system. The switching system performs the complex switching operations. Physically, each wireless switch emulates link interfaces in its connections to the switching system's communications control and data media. Logically, each of the wireless switch units communicates with a control processor controlling the operations of the switching system as if each of the wireless switches was a set of individual station sets. Each wireless switch is assigned a set of wireless sets. Each of the wireless sets has a unique telephone number which the control processor of the switching system identifies with a physical position on the communication media. Upon receipt of an incoming call for a particular wireless set, the control processor directs the voice and control information of the call to the wireless switch that is emulating what the control processor believes is a station set attached to the switching system. If the wireless set is registered on a base station attached to the assigned wireless switch, then the call is completed via the assigned wireless switch and the base station with the wireless switch directly handling the communication between the wireless set and the control processor. If the wireless set is registered on a base station connected to another wireless switch other than the assigned wireless switch, the assigned wireless switch receives the call controlinformation from the control processor communicates this information to the other wireless switch. The assigned wireless switch then continues to relay all control information being exchanged between the control processor and the other wirelessswitch.

Title: Service node for a telephony network
Inventor: JOHNSTON JOHN GRIFFTH
IPC: H04M3/42
Filed: 1995-08-01
Abstract: A service node provides a shared added value service within a telephony network, such as a public switch telephone network. Peripheral devices (21, 22, 23), such as speech applications platforms shared announcement platforms and message recording platforms, are connected to a switch (25) which operates under the control of a central control computer (24). The switch includes distributed processors (38, 52) responsive to externally originating signals, such as DTMF signals, generated while calls are being processed. The distributed processing devices supply information derived from said signals to the central control computer. Thus, it is no longer necessary for a central control computer to examine on-going calls in order to detect the presence of DTMF signalling. Detection of DTMF signalling is performed locally and information is returned back to the control computer only when relevant information has been detected. In this way, the size of the switch may be increased relative to the size of the control computer and the level of bandwidth required between the control computer and the switch is significantly reduced.
