Title: Apparatus for reducing the risk of undesirable parameter drift of an adaptive filter used for echo cancellation
Inventor: ANDRE TORE M
IPC: H04B3/23
Filed: 1992-12-17
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for reducing the risk of undesirable drifting of the parameters, so-called bursting, of an adaptive echo filter, which is coupled between a receiving branch and a transmitting branch included in a four-wire loop.  A difference signal which contains no echo from the receiving branch is generated in the transmitting branch in a known manner.  The apparatus includes an adaptive filter which is coupled between the transmitting branch and the receiving branch and which functions to generate a compensation signal from the difference signal when transmitting narrowband signals from a near-end.  The compensating signal is subtracted from a signal which appears in the receiving branch and the filter is updated in a manner to minimize the correlation between the difference signal and the input signal of the echo filter.  A relatively small filter is sufficient to essentially eliminate this correlation when transmitting signals which, at maximum, consist of some few single sinusoidal tones.

Patent CA-2146806-A1 (CA)
Title: Continuous pressure difference driven adsorption process
Inventor: LACAVA ALBERTO
IPC: B01D53/06
Filed: 1995-04-11
Abstract: A continuous pressure driven adsorption process for separating a multi-component gaseous mixture. In accordance with the method, the multi-component gaseous mixture is passed through a first portion of the adsorbent to adsorb one or more preferentially adsorbed components while a second portion of the adsorbent is regenerated.  The multi-component mixture is passed through the first portion of the adsorbent in sections and the second portion of the adsorbent is regenerated in sections. The sections forming the first portion of the adsorbent become successively less saturated and the sections forming the second portion of the adsorbent become successively more concentrated in the more preferentially adsorbed component. A product stream is expelled from the less saturated section of the first portion of the adsorbent. The product stream is enriched in the less preferentially component(s). Masses of adsorbent are continually being shifted between the first and second portions of the adsorbent so that the mass of adsorbent forming the regenerated section is shifted to the first portion of the adsorbent and used to form the least saturated section. The mass of adsorbent forming the most saturated of the sections is shifted to the second portion of the adsorbent and used to form the non-regenerated section. The masses are shifted at a sufficiently high frequency to maintain the sections forming the first and second portions of the adsorbent in their successively less saturated and successively more concentrated states.

IPC: B22D11/16
Filed: 1995-06-20
Abstract: Molten metal is poured into a casting space bounded by the cylindrical surfaces of two counter-rotating rolls (1,1') and two lateral retaining walls (3), and a thin solidified prod. is extracted from this space. A measured thrust is exerted on the retaining walls (3) parallel to the roll axes, in order to press them against the roll faces (11). The drag on each retaining wall in the direction of the casting motion is measured. The measured values of thrust and drag are used to derive a quantity which is indicative of the friction conditions in the contact zone between the retaining walls and cylinder faces. This quantity is compared with a predetermined value, and the comparison result is used for control of casting parameters. <IMAGE>

Inventor: WARD MICHAEL G
IPC: H01L21/285
Filed: 1994-01-10
Abstract: A multi-step method of filling submicron vias with aluminum includes an initial deposition of about 1000 angstroms of aluminum which is sputter deposited at a temperature of about 150 °C. Subsequently, a layer of an aluminum germanium alloy is deposited, again about 1000 angstroms at 150 °C or less. A third layer of aluminum without germanium is deposited at a temperature of about 150 °C. Approximately 1000 angstroms is deposited. This is followed by a final aluminum deposition which is conducted at 450° to 500 °C to deposit 5000 to 15,000 angstroms of aluminum in total. The two depositions of aluminum, at the relatively low temperature of 150 °C, prevents the germanium from precipitating and also permits the germanium to diffuse into these layers which increases the overall melting temperature of the deposited metal so that at subsequent higher treatment temperatures, the metal does not dewet the via surface.
Patent CA-2154812-A1 (CA)
Inventor: BADGER DAVID MARK
IPC: H04N5/44
Filed: 1995-07-27
Abstract: A more rapid charging of an integrating capacitor of a PLL is provided when large frequency changes are desired. In one embodiment, the phase locked loop (PLL) circuit sinks or sources current to charge or discharge the integrating capacitor. A threshold voltage proportional to a current through the capacitor turns on a circuit which sinks or sources more current of the proper polarity to the integrating capacitor from an external source until a PLL lock is achieved. Once the lock is achieved, if a small correction current is required by the PLL, the small correction current is below a threshold required to actuate the augmenting circuit, and the PLL loop behaves in the usual manner as if the augmenting circuit were not present. In another embodiment, the integrating capacitor is reduced in value by switchably connecting a second capacitor in series with the integrating capacitor so that the total reduced capacitance of reduced value can be charged more quickly.
