Title: Process for preparing alkylbenzene
Inventor: DYROFF DAVID R
IPC: C07C7/148
Filed: 1992-06-26
Granted: 2003-01-21
Abstract: There is disclosed an improved process for the production of linear alkylbenzene wherein monoolefins are reacted with benzene in a hydrogen fluoride catalyzed reaction followed by recovery of the alkylbenzene. An alumina treatment step is included which removes organic fluoride impurities in order to prevent release of hydrofluoric acid in downstream equipment.

Title: Process and apparatus for the determination of halftone percentage values
Inventor: ZIMMERMANN BRUNO
IPC: H04N1/46
Filed: 1992-08-18
Granted: 2003-02-18
Abstract: The invention relates to the use of a spectrophotometer connected with a computer to measure and store a solid color atlas in the computer. The halftone percentage values necessary for the adjustment of a given color are calculated by determining the desired color coordinates of the color involved and entered into the computer. The latter calculates from them, using the stored color atlas and a regression method, the halftone percentage values sought. Tn the process, with the aid of printing characteristics, stored color adaptations to prevailing printing conditions can be brought up to date without the need for the preparation of a new solid color atlas.

Patent CA-2088547-C (CA)
Title: Method and apparatus for encoding a digital image signal
Inventor: OGURO MASAKI
IPC: H04N21/236
Filed: 1993-02-01
Granted: 2002-11-05
Abstract: A digital image signal is encoded for recording by placing in a sync block approximately an integer number of macro blocks representing orthogonally transformed image data for a certain portion of the image. When a sync block is reproduced at high speed, the reproduced data therein corresponds to a displayable portion of the image including DC components and both low and high frequency AC components. Also, each sync block contains fixed length areas for the orthogonal transform coefficient data according to the 4:1:1 (or 4:2:0) format in which four blocks of luminance coefficients and two blocks of color difference coefficients represent a certain portion of an image, and also contains at least one fixed length overflow area for the high frequency coefficients which exceed the capacity of the fixed length coefficient areas. An error in the low frequency coefficients in the fixed length areas does not harm the high frequency coefficients since they are in separately addressed areas. Before a set of macro blocks is compressed into variable length encoded data, with the amount of encoded data for each set being kept within a target value so as to fit into fixed length recording tracks, the macro blocks are shuffled so that the central portions of an image are at the beginning of the set for reducing the noticeability of errors in a reproduced image.

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: Swinging blade guard assembly
Inventor: TERPSTRA DANIEL A
IPC: B23D45/14
Filed: 1993-06-30
Granted: 1996-02-20
Abstract: A swinging blade guard assembly for a motor driven saw blade movable from an upper at rest to a lower operational position is disclosed.  An upper blade guard is fixed to a pivotally mounted supporting arm that carries the motor driven saw blade and upper blade guard.  A lower swinging blade guard is pivotally mounted to the upper blade guard for fully covering the blade in its at rest position and for exposing the saw blade when moved to its operational position.  The swinging blade guard assembly includes an elongated link that is pivotally attached at one end to a frame support and includes a pre-configured slot at an opposite end which receives a slidable pin attached to the lower swinging blade guard adjacent its pivotal mounting to the upper blade guard.  A bearing element is also attached to the upper blade guard in laterally spaced relationship to the pin for engaging an upper surface of the elongated link.  Rotation of the saw blade from an upper at rest to a lower operational position causes the bearing to press against the side of the link while also causing edge surface areas surrounding the pre-configured  slot in the link to press against the pin to rotate the swinging blade guard assembly for exposure of the saw blade.  A pre-configured shoulder on the upper surface of the elongated link cooperates with the pre-configured slot to control exposure of the lower swinging blade guard relative to the saw blade, by facilitating rapid rotation of the guard during initial downward movement of the saw blade with subsequent slower rotation of the guard during the remainder of the saw blade travel.

Title: Process and apparatus for recovering sulphur from a gas stream containing hydrogen sulphide
Inventor: BUCHANAN JOHN S
IPC: B01D53/86
Filed: 1993-04-14
Granted: 2002-12-24
Abstract: A method and apparatus for removing sulphur from a gas stream containing at least one sulphur compound, comprising cumbusting said gas stream with an oxygen containing gas in an incinerator (10) to convert the or each sulphur compound to at least one sulphur oxide. A gas stream is then withdrawn from the incinerator, which contains the or each sulphur oxide. The sulphur oxide containing gas stream is then directed to an ab-sorber (12) having an absorbent bed adapted to remove sulphur compounds. The absorbent bed is then contacted with a hydrog-en and/or hydrocarbon containing stream to regenerate said ab-sorbent bed by reducing the sulphur compounds absorbed in said absorbent bed to hydrogen sulphide and/or sulphur diox-ide, and thereby forming off gas stream containing hydrogen sulphide and/or sulphur dioxide. Finally, sulphur is recovered from said hydrogen sulphide and/or sulphur dioxide bearing stream. The sulphur can be recovered by a Claus sulphur rec-overy process (16). The hydrogen sulphide containing gas stream can be ammonia acid gas stream, thereby causing N2 to be formed in the incinerator. The N2 is not absorbed in the ab-sorbent bed.
