Title: Magnesium pressure casting
Inventor: MURRAY MORRIS TAYLOR
IPC: B22D17/00
Filed: 1998-11-30
Abstract: The provision or use, for the pressure casting of magnesium alloy in a molten or thixotropic state with a pressure casting machine having a mould or die which defines a die cavity, of a metal flow system which includes a die or mould tool means which defines at least one runner from which molten magnesium alloy is able to be injected into the die cavity. The metal flow system is of a form providing for control of metal flow velocities within the flow system, whereby substantially all of the metal flowing throughout the die cavity is in a viscous or semi-solid state. Filling of the die cavity is able to proceed progressively by semi-solid fronts of metal moving away from a gate or other site of injection. The flow of magnesium alloy from the runner may be via at least one controlled expansion region of the metal flow system in which region the metal flow is able to spread laterally, with respect to its direction of injection, with a resultant reduction in its flow velocity relative to its velocity in the runner.

Title: Frequency plan revision within a cellular telephone system
Inventor: SPORRE MATTS
IPC: H04W16/04
Filed: 1998-12-18
Abstract: Downlink interference on highly uplink interfered allocated frequencies and corresponding candidate frequencies for reallocation is estimated (208, 210).  The estimates are then utilized to narrow the number of candidate frequencies (212) and highly interfered frequencies (214) to be considered for reallocation (216). The estimation of downlink interference on a selected frequency is made by having a mobile station (20) measure (108) signal strength on the control channel frequencies of neighboring cells which are allocated to that selected frequency. From these measurements, a signal strength histogram is generated (112) for each neighboring cell, and a percentile (114) value is calculated for each histogram. These percentile values for the neighboring cells, minus a selected delta value (where appropriate), are then summed (116) to generate a value estimating the downlink interference for the selected frequency. The selected delta value is applied (116d) where the selected frequency in the neighboring cell comprises a traffic channel frequency.

Title: Epaississeur
Inventor: STOTZ WOLF GUNTER
IPC: B01D33/04
Filed: 1999-02-10
Abstract: L'invention concerne des procédés et des dispositifs correspondants pour égoutter par voie mécanique, de façon continue, des suspensions (12) ou des boues renfermant de l'eau, notamment des suspensions de vieux papiers ou des boues d'épuration, entre une bande de toile (1) et une surface de compression (7) sans fin qui se déplace dans la direction de défilement des suspensions et présente une surface lisse fermée. La gâteau de suspension (13) à égoutter est comprimé entre la bande de toile (1) et la surface de compression (7). Pour obtenir la pression de compression nécessaire, la bande de toile entoure la surface de compression cylindrique en exerçant une tension longitudinale pendant l'égouttage, l'eau exprimée (14) étant éliminée du gâteau de suspension (13) par l'intermédiaire de la toile. Selon l'invention, il est prévu des dispositifs qui allongent la durée pendant laquelle la pression d'égouttage de la bande de toile agit sur le gâteau de suspension et qui, simultanément, augmentent considérablement la pression de compression sans empêcher l'écoulement de l'eau exprimée. Le procédé de l'invention fait passer la pression de compression d'environ 1 bar, valeur appliquée jusqu'à présent, à des valeurs pouvant atteindre jusqu'à 100 bars. Ce procédé peut également être intégré dans des procédés d'égouttage connus, pour augmenter la consistance de substances solides, sans pour autant accroître considérablement l'espace nécessaire ou la complexité d'utilisation.

Title: Improved interface between channel units of multiple local exchange carriers
Inventor: BROWN RONALD ROBERT
IPC: H04Q11/04
Filed: 2000-11-23
Abstract: In accordance with the invention, an interface between an incumbent local exchange carrier's central office terminal and a competitive local exchange carrier's remote terminal is provided by an Integrated Services Digital Network interconnection. Such a connection provides two basic data channels of 64 Kbps each and at least one utility channel. The ISDN signal can be carried over a single wire pair. The interface may be used to interconnect one or two digital channels.      The channel units may be designed to remove the robbed bits from the data channels and place them in the utility channels. Further, the utility channel may be employed to transmit frame phasing information so that the networks can synchronize their robbed bit signaling so that both networks use the same bit positions for robbed bit signaling thus minimizing data bandwidth reduction due to robbed bit signaling.

Abstract: An electronic filter operates as a correlator that provides a discrete approximation of an analog signal. The analog to digital conversion is integrated directly approximation calculation. An array of sample and hold circuits or single bit comparators provide outputs to a series of multipliers, the other input of which is a coefficient value of a Fourier series approximation of the desired frequency response. Each of the sample and hold circuits samples sequentially in time and holds its sample until the next cycle. Thus the sample point rotates in time through the array and each new sample is multiplied by a different coefficient.      The output of the multipliers is summed for evaluation.
