Title: Vacuum extrusion apparatus and method
Inventor: SADINSKI ROBERT L
IPC: B29C48/07
Filed: 1997-08-11
Abstract: An extruder (13) projects through a bulkhead (10) adapted to form part of a vacuum chamber (11), and a die (14) is mounted on the end of the extruder within the vacuum chamber. The extruder projects through a gland seal (40) which is formed in a sleeve surrounding the extruder.

Title: Sand reclamation
Inventor: WARD STUART PETER
IPC: B22C5/00
Filed: 1997-10-29
Abstract: A carbohydrate is added to sand, which has been used to make foundry moulds or cores, and which has been bonded using an alkaline resol phenol-formaldehyde resin, prior to reclamation of the sand by a thermal reclamation. The thermal reclamation may be done in other equipment, for example a rotary thermal reclamation unit, but is preferably done in a fluidised bed reclamation unit. The carbohydrate is preferably water soluble and is added to the used sand as an aqueous solution.  The carbohydrate may be for example a monosaccharide, such as glucose, mannose, galactose or fructose, or a disaccharide such as sucrose, maltose or lactose. The carbohydrate may also be a carbohydrate derivative such as a polyhydric alcohol (e.g. ethylene glycol, glycerol, pentaerythritol, xylitol, mannitol or sorbitol), a sugar acid (e.g. gluconic acid), or a polysaccharide derivative (e.g. a starch hydrolysate, i.e. a glucose syrup or a dextrin). The amount of carbohydrate used in the reclamation process is usually of the order of 0.25 %  to 5.0 % by weight based on the weight of used sand.

Title: Fault detection system for an amplified optical transmission system
Inventor: MACDONALD ROBERT I
IPC: H04B10/08
Filed: 1999-05-20
Abstract: A fault detection circuit and method of detecting catastrophic faults for example from a total line outage due to a transmission waveguide being inadvertently cut, includes tapping a sample of the amplified transmission multichannel signal light for analysis. The tapped light is then fed to a periodic filter such as a Mach Zehnder interferometer or a Fabry Perot etalon having a free spectral range and, phase at one output that coincides with the channel central wavelengths of the transmission system. Another output of the periodic filter provides an output response that is phase shifted by 180 degrees. Two output signals from the two output two output signals are then compared, in one embodiment by using a photodiode bridge. When one output of the periodic filter has a substantially different signal energy than the other, it is assumed that no faults occur. Conversely when the two outputs are substantially similar, it is assumed that a catastrophic fault has occurred.

Title: Method for providing telecommunications services as well as switching nodes, service control nodes and switching system
Inventor: KAISER BERNHARD
IPC: H04L69/14
Filed: 1999-06-16
Abstract: The invention relates to a method for providing telecommunications services as well as a switching node, a service control node and a switching system for implementing the method. A call request by a subscriber (A) of a telecommunications network (T_NET) activates a service switching function (SSF) executed by the control (CONTR) of the switching node (SSP) to send a service request message to a service control function (LSCF1) whereupon the service control function (LSCF1) controls the provision of the telecommunications service. The control (CONTR) of the switching node (SSP) reroutes the request message to a LAN, which connects the system platform (SPL1) of the control (CONTR) of the switching node (SSP) with the system platform of the service control node (LSCP1, LSCP2). The service control node (LSCP1, LSCP2) thus connected via the LAN now executes the service control function (SCF1). To provide the service, a service switching function (SSF) exchanges INAP messages (INAPM) with the service control function (SCF1), which messages are transported by means of a LAN protocol between the switching node (SSP) and the service control node (LSCP1).

Abstract: Electroluminescent laminates having a thin film electroluminescent oxide phosphor layer on insulating substrates. Thin film EL laminates are produced using high dielectric constant layers, such as SrTiO3 and BaTiO3 next to the oxide phosphor layer on one or both sides of the oxide layer, primarily as stable charge injection, and trapping interface layers, and to increase the electric field in the phosphor. Electric breakdown protection through self-healing has been provided by traditional low K dielectrics in combination with an appropriate choice of adjacent electrode. The high dielectric constant materials employed also provide for a high capacitance layer, thereby increasing the electric field in the phosphor and increasing the charge transfer into the phosphor during emission. These thin film EL laminates demonstrate steep brightness-voltage behavior and have been prepared using green and red electroluminescent oxide phosphors.
