Abstract: ABSTRACT     Packet switching network with first (DN) and second (RN) cascaded pares including first and second switching modules respectively. In the second switching modules the path selection is controlled by routing information contained in the packets. In the first switching modules this selection is performed without using routing information only for a path set up packet, whilst for the following packets use is made of routing information on the route followed by the path set up packet.  Each module decides to multiplex an input stream on an output only when a calculated traffic load is smaller than a limit value.  This load is calculated from traffic load parameters contained in the path set up packet.

Title: Gelable compositions and use thereof in steam treatment of wells
Inventor: MUMALLAH NAIM A
IPC: C09K8/88
Filed: 1988-01-13
Granted: 1992-10-20
Abstract: Abstract of the Disclosure A gelable composition is provided which can be injected into a well prior to steam treatment of the well. The composition comprises water, a water-dispersible polymer, a water-dispersible first crosslinker and a water-dispersible second crosslinker, wherein the first and second crosslinkers  have  differing  temperature  responsive  crosslinking characteristics over the temperature range of about 70°F to about 400°F so as to enable crosslinking of the polymer and gelation of the composition over substantially the entire temperature range.  Injection of the composition into a "cold" well followed by steam treatment of the well causes the polymer to undergo a two stage crosslinking reaction which produces a particularly effective and stable gel in diverting steam from "thief zones" in the formation surrounding the well.

Abstract: ABSTRACT CUTTING AND THE LIKE TOOLS         The invention relates to cutting and the like tools and is particularly concerned with the cutting of an internal weld bead from within plastics pipes.  It is well-known to remove an external weld bead from the junction between two plastics pipes, not only to provide a smooth external profile but also to allow the weld between the pipes to be inspected.           The costs and difficulties in removing the internal beads at the welded junction has frequently resulted  in the internal bead being left, and when the internal weld cannot be inspected, and turbulence created in gas or fluid being driven through the pipeline results in a higher power requirement.           One object of the invention is to provide a simple and effective means of removing an internal weld bead, which objective is met by a construction characterised by a body member (1), adjustable support means (23, 28) on the body member to locate the body member within a pipe, a motor (2) with the body member, a feed screw means (7) slidably mounted on  shaft (3) extending from the motor, the feed screw means (7) engaging a threaded bore in a drive screw means (8) located in the body member, and there being cutter and the like means (21, 30) removably secured to the end of the feed screw means.

Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE         In order to compensate for frequency deviation without using a pilot signal and associated apparatus, a channel number identification code is added to a transmit signal at an earth station transmitter.  Each channel unit (demodulator) of a receiving earth station is arranged to extract a channel identification code from a received signal and to compare this with a preset code assigned to that channel.  In the event that the recieved channel idenfication code does not coincide with that of the instant channel, the channel determines the number of channels by which deviation which has occured and adjusts its receiving frequency accordingly.

Abstract: ABSTRACT OF THE DISCLOSURE A hollow shell recirculation arch underlies and supports at least one maple sap vaporizing pan.  The arch is formed of inner and outer sheet metal shells.  The inner shell is upwardly open and is sized smaller than the outer shell so as to form a space therebetween defining a first heat exchange chamber transverse bridge wall is interposed within the inner shell, intermediate of the inner shell front wall and a rear wall, and separating the inner shell into a fire box and a second heat exchange chamber.  Fire brick lines the interior surfaces of the fire box.  Preferably the transverse sidewalls of the inner shell are V-shaped to concentrate and reflect the heat upwardly through the open top of the inner shell against the vaporizing pan. A smoke stack assembly includes a horizontal smoke stack pipe fixedly mounted to the arch and projecting through the rear walls of the outer and inner shells and extending over the major length of the regenerative heat exchanger section of the arch and terminates in an open end facing the bridge wall and spaced slightly therefrom.  Fresh combustion air is forced through the first heat exchange chamber between the inner and outer shells, flowing the length of the arch for preheating the combustion air. Passages provide a primary air stream feed into the combustion chamber along with secondary air through the bridge wall which is preferably hollow and bears a plurality of short length nozzles discharging secondary air into the fire box.

Granted: 1993-01-05
Abstract: SEALING DEVICE FOR INTRODUCING    CEMENT INTO A BONE CANAL                      ABSTRACT A proximal femoral sealing device 10 is disclosed for use in the application of bone cement under pressure to a surgically prepared medullary canal 15 of a femur prior to the implantation of a hip prosthesis. The proximal femoral sealing device 10 is formed of a generally solid body member 12 with a passageway 26 and a flexible annular wall member 14 extending from the body member 12.  The sealing device 10 has an anatomically shaped outer surface 13, corresponding to the exposed endosteal surface 11 of a prepared medullary canal 15.  A chamber 16 defined by a flexible annular wall 14 and the body member 12 opens into the medullary canal 15.  In turn, the passageway 26 communicates with the chamber 16 and permits insertion of a cement nozzle 27 therethrough into the chamber. In operation, the proximal femoral sealing device 10 is placed within the proximal end of a surgically prepared medullary canal 15.  The canal 15 and chamber 16 of the sealing device are filled with cement resulting in the expansion of the flexible annular wall member 14 against the exposed endosteal walls 11 of the medullary canal 15 by cement pressure within the chamber thereby forming a pressure seal.  The escape of cement through the open end of the excavated medullary canal 15 is prevented via this pressure seal insuring that the applied cement is properly pressurized and that the medullary canal 15 is prepared for implementation of the prosthetic device 10.  A method of providing cement under pressure to the exposed endosteal surface 11 of a medullary canal 15 is also disclosed using this proximal femoral sealing device 10.
