Title: Growth of very uniform silicon carbide epitaxial layers
Inventor: KORDINA OLLE CLAES ERIK
IPC: C23C16/32
Filed: 1998-12-14
Abstract: An improved chemical vapor deposition method is disclosed that increases the uniformity of silicon carbide epitaxial layers and that is particularly useful for obtaining thicker epitaxial layers. The method comprises heating a reactor to a temperature at which silicon carbide source gases will form an epitaxial layer of silicon carbide on a substrate in the reactor; and then directing a flow of source and carrier gases through the heated reactor to form an epitaxial layer of silicon carbide on the substrate with the carrier gases comprising a blend of hydrogen and a second gas in which the second gas has a thermal conductivity that is less than the thermal conductivity of hydrogen so that the source gases deplete less as they pass through the reactor than they would if hydrogen is used as the sole carrier gas.

Title: Two-part hair dye compositions containing polyether polyurethanes and conditioning agents
Inventor: KHAN ZUBAIDA
IPC: A61K8/00
Filed: 1998-12-09
Abstract: The present invention describes a two-part oxidative hair dye composition which comprises in one or both component parts at least one polyether polyurethane in combination with at least one cationic conditioning agent. The two component parts of the composition comprise a dye component composition, which includes primary intermediates and couplers, and a developing component composition, which includes an oxidizing agent, such as hydrogen peroxide. It has surprisingly been found by the present inventors that nonionic polyether polyurethane polymers and cationic conditioning agents contained in the oxidative hair dye compositions of the present invention impart and significantly enhance additional conditioning and rheological benefits to the hair. Other components commonly used in oxidative hair dye products can be added to one or both component parts of the compositions of the present invention. After mixing the two component compositions, the resulting hair dye composition mixture is thick, conveniently applied, and provides superior rheological and conditioning properties to the hair.
Patent CA-2317823-A1 (CA)
Inventor: JOHNSON HEATH ALLEN
IPC: H01R13/622
Filed: 2000-09-07
Abstract: An anti-decoupling arrangement for an electrical connector includes a spiral lock clutch, a spring ring, and a separate ratchet wheel or tooth ring having a plurality of radial cuts, all surrounding the connector shell and sandwiched between a flange or shoulder on the connector shell by a conventional snap ring. The tooth ring is situated in a space between the thread of the coupling nut and the flange or shoulder that forms the inner surface of a recessed area with the coupling nut. The shell includes two grooves, one for the spiral lock clutch and the other for the snap ring, that are behind the flange or shoulder towards the rear of the connector, the shell providing axial alignment of all components except the spring ring. The tooth ring also includes extensions that cooperate with a notch or slot in the coupling nut so that the tooth ring rotates with the coupling nut, while the spring ring includes an extension in engagement with a notch in the spiral lock clutch so that the spring ring is locked against angular rotation relative to a spring ring. Preferably, the spring ring member is a self supporting ring that has spring tines or beams of a given number located angularly around its radial wall.  These tines provide the ratchet mechanism when the tines glide over the radial cuts of the tooth ring in the uncoupling direction. This provides a free running clutch in the coupling direction and a torque/ratchet mechanism in the uncoupling direction. Alternatively, the decoupling assembly may be flipped by 180 degrees, the tooth ring being replaced by teeth extending axially from an inwardly extending flange in the coupling nut.

Title: Memory management in a receiver/decoder
Inventor: DECLERCK CHRISTOPHE
IPC: H04N21/43
Filed: 1999-03-29
Abstract: A device management module (11) particularly for use in a receiver/decoder for a broadcast digital television system in which received signals are passed through a receiver to the receiver/decoder and thence to a television set. The module (11) couples incoming messages from port units (10) to application modules (12). A memory (13) coupled to the unit (11) has a buffer area (13-B) and a FIFO area (13-F), controlled by a buffer controller/handler (14-B) and a FIFO controller/handler (14-F) respectively. An incoming message can be passed into a buffer, and retrieved from the buffer by the application to which it is directed; two different operating modes are available for this. Alternatively, such a message can be passed to a FIFO; the FIFO handler acts as a low-level application which can pass the message on to a high-level application without that application having to take any action and without having to wait for the full message to be received. Messages passing through the FIFO are may be combined into an MPEG signal stream.

Filed: 2001-02-19
Abstract: To identify interference from other data carrying subscriber loops (i.e., from loop disturbers), a power spectral density sample may be obtained from the subscriber loop under consideration based on at least one measurement while the loop is not transmitting data. The sample power spectral density may then be correlated with each one of a set of known power spectral densities. Each known power spectral density represents a power spectral density in a loop which is not transmitting data in the presence of one of (i) no subscriber loop disturbers, (ii) a particular subscriber loop disturber, and (iii) particular subscriber loop disturbers. Based on the correlations, subscriber loop disturbers may be recognised.

The first ion reflector 18 is disposed at the exit 5 of the drift region 2 to reflect back towards the entrance 4 ions which are travelling towards the reflector 18 in the drift region 2. The second ion reflector 19 is disposed in juxtaposition to the first ion reflector 18 to reflect packets of ions back towards the first ion reflector 18 through at least a portion of the drift region 2 so that the packet of ions may be reflected to and fro between said first 18 and second 19 ion reflectors and undergo a number n of reflections at the second ion reflector 19. A detector 20 is disposed to detect at least some packets of ions reflected by the first ion reflector 18 which do not enter the second ion reflector 19. The number of reflections at the second ion reflector 19 may be selected by adjustment of an inclination of the initial direction to the axis 3.
