Title: Casing Spacers
Inventor: GRAY PATRICK H JR
IPC: F16L9/18
Filed: 1996-04-17
Abstract: Casing spacers for isolating carrier pipe mechanically, galvanically, and chemically from pipe casings. The spacers may be attached using fasteners to pipe joint restrainers or other ring structures which encircle carrier pipe. The spacers are more efficient to install in the field, provide robust mechanical structure and physical stability which does not degrade over time, provide additional protection to the pipe joints, and, because they may be attached to conventional structures instead of requiring an integral ring structure for encircling a pipe, alleviate the distribution and inventory problems encountered by conventional systems in which the casing spacer runners are attached to an integral ring structure which must conform to the carrier pipe size and the casing inner diameter.

Title: In-train wheel changing method & device
Inventor: CRISP IAN
IPC: B61K5/04
Filed: 1996-07-05
Abstract: The invention provides a method of replacing the wheels of a railroad car while the railroad car is at rest on rail tracks. Most advantageously, the rail car need not be uncoupled from adjacent cars. The method also has the advantage that rail cars are jacked at the coupler thereby making the method applicable to all types of cars including grain and oil cars which cannot be jacked in their midsections. The method comprises the steps of: releasing the wheel to be replaced from the rail car; transverse insertion of a jack between the rails and the underside of the coupler; actuating the jack to lift the rail car supported upon the underside of the coupler; removing the wheel to be replaced; replacing the wheel; actuating the jack to lower the rail car onto the replaced wheel; securing the replaced wheel to the rail car. The invention also provides a jack for raising and lowering an end of a railroad car having a coupler extending therefrom, the railroad car being at rest on longitudinal rail tracks, the jack being disposed between the rails and the underside of a coupler, the jack comprising: a base supported upon the rails; a cap disposed in parallel above the base; coupler support means for supporting the rail car coupler upon the cap; and lifting means, disposed between the base and cap, for selectively raising and lowering the cap relative to the base between a collapsed position wherein the jack is clear of the rail car to facilitate transverse insertion between the rails and the underside of the coupler, and a maximum lift extended position. Advantageously the coupler support means comprise a travelling table means for shifting the coupler transversely thereby aligning the rail car wheel flanges on the rail head.

Abstract: Nucleic acid encoding subunits of a polypeptide folding complex containing TCP-1 is useful in expression of the subunits for assembly of the complex in vitro or in vivo. The complex promotes folding of polypeptides, such as tubulin, e.g. following recombinant expression. The sequences share a high degree of homology but the C-terminii are sufficiently different to enable peptides with sequences derived therefrom to be used in obtaining antibodies specific for the various subunits, i.e. able to distinguish between them. The antibodies may be used in analysis and design of complexes able to fold different polypeptides.

Title: Pager-controlled wireless radiotelephone
Inventor: GAULKE DAVID ALAN
IPC: H04W52/02
Filed: 1996-12-10
Abstract: An integrated pager and cellular phone (123) includes circuitry (502, 515) that responds to receipt by the pager (122) of an incoming-call-indicative paging signal by connecting the cellular phone (121) to a battery power source (513). This activates the cellular phone, whereupon it registers with a base station (107-109) and thus becomes able to receive the incoming call.  The circuitry further responds to receipt by the pager of a second paging signal by disconnecting the cellular phone from the battery power source.  This allows the cellular phone to be kept in a deactivated condition and not draining battery power at times when thecellular phone is not in use, without missing incoming calls, and does so automatically, without intervention of the user of the cellular phone.

Title: Multi-core atm switch with cells in the core from an inlet for an outlet being aligned
Inventor: NICHOLS STACY W
IPC: H04L12/931
Filed: 1997-02-06
Abstract: A multi-stage ATM switch has a plurality of inlet stage fabrics, core stage fabrics and outlet stage fabrics. ATM cells routed by the switch have destination fields including (i) an identification of the outlet stage fabric and (ii) an identification of the outlet port. Cells incoming to a given inlet stage fabric are queued up in queues representing each of the outlet stage fabrics. A queue having at least the number of cells as there are core stage fabrics (or one having a lesser number of cells where cells have been waiting longer than a pre-defined time) is identified and, in a time slot, cells are transmitted from the front of the identified queue, in parallel, one to each of the core stage fabrics (with blank make-up cells being sent, as necessary, where the identified queue had less cells than there are core stage fabrics). In the core stage fabrics, the incoming cells are again queued up in queues representing each of the outlet stage fabrics and then cells are transmitted from the heads of these queues to the outlet stage fabrics. At the outlet stage fabrics, incoming cells are queued in queues representing the outlet ports to which these cells are destined and cells are output from the heads of these queues.

Title: Method of power regulation in a satellite telecommunication network with at least two satellites in view
Inventor: CALOT GUILLAUME
IPC: H04B7/005
Filed: 1997-02-12
Abstract: The invention provides a method of regulating the power of transmission between first and second stations in    a   multiple    satellite   visibility    satellite telecommunication  network.    The  method  comprises  the following cyclic steps:  regulation,  for each of said N channels,  of an  isolated transmit power  level  command signal such that when it commands the power at which the first station transmits the first isolated signal in each channel the quality level of the corresponding isolated second signal received by the second station is equal to a reference quality level, and regulation, for all of the N channels, of N combined transmit power level command signals such that when they command the levels at which the  first  station  respectively  transmits  the  N  first combined signals on the N channels the quality level of the global signal received formed from the N combined second signals is equal to the reference quality level. Depending on whether the isolated command signal having the minimal level is such that this minimal level is less than or greater than a maximal tolerated isolated command level,  the  minimal  level  isolated  command  signal  is selected  to  command  the  power  with  which  the  first station  transmits  a  call  signal  in  the  corresponding channel, or the N combined command signals are selected to  command  the  power  with  which  the  first  station transmits  respective  combined  call  signals  on  the  N channels.
