Title: Fluidized bed reactor
Inventor: BEREZOWSKI RAFAL
IPC: B01J8/32
Filed: 1993-04-07
Abstract: ABSTRACT OF THE DISCLOSURE Common problems in fluidized bed reactors include uneven distribution of particulate material in the bed, poor contact between fuel and fluidized bed particles, and difficulties in separating solids from flue gases.  These problems are solved in a fluidized bed reactor including a rectangular cross section, elongated housing containing a large area, lower reactor chamber and a smaller area, freeboard, fluidizing air being fed into the bottom of the reactor chamber via a plurality of nozzles in parallel inlet pipes, the nozzles being inclined slightly outwardly towards opposite sides of the housing; a bottom central solids discharge pipe for recycling a portion of the solids to a fuel/sorbent inlet in one side of the housing above the fluidized bed; a flow divider near the top of the fluidized bed when activated for diverting particles outwardly in a spiral motion towards the sides of the bed; shelves in the freeboard for causing the flue gas to follow a circuitous route through the freeboard, causing the settling of entrained solids; water pipes lining the housing and extending between bottom and top boilers for creating steam; separators for receiving flue gas to remove solids therefrom for recycle to the fluidized bed; and a heat exchanger for preheating fluidizing/combustion air before introducing such air into the fluidized bed.

Abstract: An optical fiber splicing device includes a clip (20) which aligns and secures cylindrical rods (28, 30 and 32) utilized within a three-rod optical fiber splicing device. The clip (20) is a generally cylindrically shaped component which is made of a resilient material and is positionable so as to encase three cylindrical rods (28, 30 and 32). The clip (20) comprises a circular body portion (22) and two protruding leg portions (24 and 26) which extend from an point on the outer periphery of clip body (22). The two leg portions (24 and 26) are constructed and oriented such that they may be manipulated to controllably expand the inner diameter of clip body (22). To facilitate an optical fiber splice or connection, the clip (20) of the present invention allows the clip body (22) to be expanded to loosen the grip on rods (28, 30 and 32) held therein, thereby allowing the optical fiber ends to be inserted between the rods. Additionally, the inner periphery of clip body (22) is adapted with a plurality of dimple pairs precisely aligned to assure proper longitudinal alignment of the three rods for an efficient and effective splice.

Title: Ski
Inventor: HEUVEL JOHAN G F
IPC: A63C9/00
Filed: 1993-05-10
Abstract: This invention relates to edging efficiency of a binding support type ski, taking advantage of the non linear relationship between edge to surface pressure and resistance to movement perpendicular to the ski edge. In the ski according to this invention, edging efficiency is enhanced by providing localized, longitudinally spaced edge to running surface high pressure sections, improving both edge control and ski directional stability. The ski comprises a novel ski runner wherein the longitudinal flex substantially resides in flanges adjacent to the ski runner side margins.

Said gas pressure within container builds until container explodes creating a loud noise and propelling paint in all directions, the paint droplets being expelled from container simulating grenade fragments and being usefull for subsequent determination of points of impact.  This de-vice is usefull in paintball wargames or in any situation where combat is simulated.
Patent CA-2101078-A1 (CA)
Title: Regeneration of hydrochloric acid
Inventor: HOLLITT MICHAEL J
IPC: C22B3/04
Filed: 1992-11-23
Abstract: The specification discloses a process for regenerating aqueous chloride leach liquors. The process involves roasting aque-ous chloride leach liquor to produce metal oxide and a gas containing HCl. The gas containing HCl is passed through a precon-centrator where it is contacted with spent aqueous chloride leach liquor. The enthalpy of the gas evaporates water from the spent liquor thereby concentrating it. At the same time the spent liquor absorbs HCl. HCl not absorbed in the preconcentrator is con-tacted with water to form hydrochloric acid. The hydrochloric acid may be mixed with the concentrated spent liquor and re-used.      Apparatus for operating the process is also disclosed.

Title: Digital storage system and method having alternating deferred updating of mirrored storage disks
Inventor: POLYZOIS CHRISTOS A
IPC: G06F11/20
Filed: 1994-06-06
Abstract: DIGITAL STORAGE SYSTEM AND METHOD HAVING ALTERNATING DEFERRED UPDATING OF MIRRORED              STORAGE DISKS                       ABSTRACT A fault-tolerant high performance mirrored disk subsystem is described which has an improved disk writing scheme that provides high throughput for random disk writes and at the same time guarantees high performance for disk reads.  The subsystem also has an improved recovery mechanism which provides  fast  recovery  in  the  event  that  one  of  the mirrored disks fails and during such recovery provides the same performance as during non-recovery periods.   Data blocks  or pages which  are to be written to disk are temporarily accumulated and sorted (or scheduled) into an order  (or  schedule)  which  can  be  written  to  disk efficiently,  which  in  a  preferred  embodiment  is  in accordance with the physical location on disk at which each such  block  will  be  written.    This  also  generally corresponds to an order which is encountered by a write head during a physical scan of a disk.   The disks of a mirrored pair are operated out of phase with each other, so that one will be in read mode while the other is in write mode.   Updated blocks are written out to the disk that is in write mode  in  sorted order,  while  guaranteed read performance is provided by the other disk that is in read mode.  When a batch of updates has been applied to one disk of a mirrored pair, the mirrored pair switch their modes, and the other disk is updated.  Preferably the updates are kept  in  a  non-volatile  memory,   which  furthermore advantageously may be made fault-tolerant as well.  During recovery a pair of spare alternating mirrored disks is introduced to which new updates  are directed,  while a background scan process copies data from the surviving disk to the new mirrored pair.
