Patent CA-2200961-A1 (CA)
Title: Process and apparatus for the manufacture of steel from iron carbide
Inventor: SINHA ASISH K
IPC: C01B31/30
Filed: 1995-12-05
Abstract: A two stage reaction for the production of steel from iron carbide is carried out in two separate but interrelated reactors (1, 36). In the first reactor (1), iron carbide, with slag formers, is fed into a feed end (2) and the reaction is well-mixed by the vessel geometry, the stirring action of below-surface injection of oxygen and iron carbide feed, and the evolution of gases from the liquid metal bath (9). The product, containing about 0.5-2 % carbon, is fed into the second reactor (36) where it is refined with subsurface-injected oxygen. The second reaction is autogenous, and the evolved carbon monoxide is fed to the first reactor (1) where it is burned with oxygen in a foamy slag, which, with post-combustion burning in the slag of CO evolved in the first reactor (1), and with iron carbide preheating with the sensible heat of the off-gas from the first reaction, makes that reaction also essentially autogenous.

Title: Movable internal platform for a disk drive
Inventor: SONDEREGGER RALPH L
IPC: G11B25/04
Filed: 1995-10-13
Abstract: A movable platform (50) is mounted on opposing guide rails (52, 54) within a disk drive (40). A head actuator (60) and a spindle motor (82) are mounted on the movable platform. The platform moves on the guide rails from a forward position to a rearward position upon insertion of a disk cartridge (10) into the disk drive. As the platform moves toward the rearward position, the elevation of the platform changes in order to bring the spindle motor in engagement with the hub of the disk cartridge. A latch member (138) is pivotally mounted on one of the guide rails for latching the platform in its forward position when the disk drive is not in use.

Title: Method and apparatus for turn coordination gain as a function or flap position
Inventor: TRAN CHUONG B
IPC: B64C13/18
Filed: 1997-04-30
Abstract: An improved method and apparatus for determining the amount of turn coordination gain in an aircraft yaw damper during a turn maneuver is disclosed. The yaw damper includes inputs from the inertial reference units of the aircraft and also from the flight management computer of the aircraft. The flight management computer provides to the yaw damper a signal indicative of the position of the flaps of the aircraft. The yaw damper includes a turn coordination gain box that receives the flap position signal and outputs a turn coordination gain value, dependent upon the flap position. Generally, the turn coordination gain value increases as the flap position is more extended. The precise turn coordination gain value for each flap position is dependent upon the particular aerodynamic characteristics of the aircraft.

Title: Fragrance precursors
Inventor: FRATER GEORG
IPC: A61K8/00
Filed: 1997-06-23
Abstract: The invention relates to fragrance precursors. In particular, the invention relates to the use of several classes of compounds which can act as fragrance precursors e.g. in cosmetic products such as deodorants and antiperspirants and in laundry products such as detergents and fabric softeners. These compounds are normally odorless or nearly so, but upon contacting the skin as for example, in skin care compositions or in personal care compositions, produce fragrances. The compounds also produce fragrances when used in the presence of lipases, e.g. as used in (laundry) detergents, thus providing a prolongation of the fabric scenting effect.    The compounds under consideration are compounds of the formula (see fig. I) The substituents are defined in the specification.

Abstract: The present invention provides reconstructing and resynchronization of wireless serial transmissions causing erroneous uncorrectable bit errors exceeding the error correction code (C Figs. 5A, 5B and 5C) capacity of frames (Fig. 5B) of digitally encoded data. Valid data is reconstructed in frames which have all erroneous uncorrectable bits within the error correction code bit held (862). A synchronization marker (S" Figs. 5A and 5B) is transmitted with each frame group which does not represent any valid data in a frame. Detection of synchronization marker (882 Fig. 26C) by the digital signal processor (726 Fig. 21) after at least one frame is determined to contain at least one erroneous uncorrectable bit. Resynchronizes the clock of the processor of the receiving  circuitry. After resynchronization of the clock (B Fig. 26B), frames beginning with at least one frame containing  at least one erroneus uncorrectable bit are reconstructed to recover data in frames which do not contain at least one erroneous uncorrectable bit and to recover valid data bits in frames containing at least one erroneous uncorrectable bit (864-868).
