Title: Apparatus for controlling the conversion gain of a down converter
Inventor: MUTERSPAUGH MAX WARD
IPC: H04B1/18
Filed: 1996-10-17
Abstract: A down converter, such as a low noise block (LNB) converter, of the outdoor unit (100) of a terrestrial microwave or satellite receiving system includes apparatus for automatically controlling the conversion gain of the down converter. In one embodiment the automatic gain control apparatus, including a gain controllable RF stage (106) and a gain control signal generator (146) for generating a gain control signal in response to the output signal of the down converter, are both included within the outdoor unit (100). In another embodiment, the gain controllable RF stage (106) is included in the outdoor unit (200), but the gain control signal generator (220) is included in the indoor unit (202) of the receiving system and the gain control signal is coupled to the outdoor unit (200) in direct or in encoded form. In the latter case, the encoded gain control signal can be coupled to the down converter via the coaxial cable (222) connected between the outdoor (200) and indoor units (202). In a receiving system which processes digitally encoded information, the error rate of the information which is decoded in the indoor unit (202) can be utilized to generate the gain control signal for the gain controllable stage (106) of the outdoor unit (200).

Title: Computer backup system operable with open files
Inventor: MALCOLM PETER BRYAN
IPC: G06F12/12
Filed: 1996-03-18
Abstract: A backup program for a computer system with a hard disk maintains a record of changes made to the data in a file being backed up. During backup both the original and update file portions or records are stored, and the backup program reads the original data while other applications read the updated data. To identify whether a read operation is initiated by the backup program or by another application, the system determines, using the stack, the source of the read request.  Alternatively it interrogates the user, process or task id. Access to the file by the backup program is guaranteed by manipulating the System File Table. It is ensured that the file is in a "good" state by delaying the start of the backup operation for a predetermined period.
Patent CA-2215048-A1 (CA)
Title: Solution for electrolytic deposition of zinc or zinc alloy coatings
Inventor: URRUTIA DESMAISON GONZALO
IPC: C25D3/22
Filed: 1996-03-11
Abstract: The invention concerns an aqueous alkaline cyanide-free solution for use in the electrolytic deposition of lustrous and blister-free zinc or zinc-alloy coatings of uniform layer thickness on substrate surfaces. Electrolytic zincor zinc-alloy baths are used for depositing zinc or zinc-alloy coatings. The layers are partly decorative and for that reason the layers must have an even lustre across a wide current density range. However, sufficiently uniform layer thicknesses cannot be obtained on complex workpiece surfaces with sharpedged structures and concave surface regions, and zinc and zinc-alloy layers deposited on such workpieces tend in addition to be more prone to blistering. These disadvantages are eliminated by a coating solution containing, in addition to the normal bath components, diallyl ammonium-sulphur dioxide copolymers of general structural formula (I) shown, and/or diallyldimethyl ammonium monomers.

Inventor: FIDKOWSKI ZBIGNIEW TADEUSZ
IPC: F25J3/04
Filed: 1997-09-24
Abstract: Procédé pour la distillation cryogénique d'une alimentation en air pour produire à haute pression de l'azote dont le degré de pureté varie de moyennement élevé (azote à 99.9 %) à ultra-élevé (moins d'une partie par milliard d'oxygène). Le procédé convient particulièrement aux cas où l'azote à haute pression est requis directement du système à colonne de distillation par souci d'éviter la contamination associée à la compression de l'azote qui est produit à des pressions inférieures. Le procédé utilise une colonne à haute pression, qui fonctionne à une pression permettant de produire l'azote directement à la haute pression souhaitée, et une ou plus d'une colonne à pression plus basse qui produit une partie de l'azote à une pression inférieure. Au moins une partie de l'azote à basse pression est comprimée et acheminée à la colonne haute pression en un point qui se trouve sous le point d'extraction de l'azote à haute pression.

Title: Magnetic bearing with reduced control-flux-induced rotor loss
Inventor: COLBY ROY S
IPC: F16C39/06
Filed: 1996-06-21
Abstract: A magnetic bearing with reduced control-flux-induced rotor loss includes a rotor (14), and a stator (12) having a plurality of slots (S1-S16) around which coils (150-156) of a first Phase A and coils (160-166) of a second Phase B are wound. The winding configuration provides a two pole magnetic field around a rotor/stator gap (15) which is sinusoidal and which can be directed to any location along the gap (15). The configuration minimizes discontinuities or sharp changes in control flux in the gap which thereby reduces rotor losses. Also, the stator tooth gap (g1) is minimized to provide smooth flux distribution along the rotor/stator gap (15). More phases and more or less stator slots may be used.
