Title: Process for the removal of mercaptans and hydrogen sulfide from hydrocarbon streams
Inventor: PUTMAN HUGH M
IPC: B01D3/00
Filed: 1995-12-07
Abstract: A process for treating a light cracked naphtha to be used as an etherification feed stock is disclosed in which mercaptans, hydrogen sulfide and diolefins are removed simultaneously in a distillation column reactor (10) using a reduced nickel catalyst. The mercaptans and hydrogen sulfide are reacted with the diolefins to form sulfides which are higher boiling than that portion of the naphtha which is used as feed to the etherification unit. The higher boiling sulfides are removed as bottoms (8) along with any C6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process.

Patent CA-2220615-A1 (CA)
Title: Braking and damping element for movable cabinet/furniture components
Inventor: JOCHUM PETER
IPC: E05F5/06
Filed: 1997-11-07
Abstract: The invention is a braking and damping element for movable cabinet/furniture components, which consists basically of a cylinder element in which a radial expandable lengthwise-moving piston is placed.  The piston is fitted rather snugly in the cylinder bore hole and has a front-sided notch, which is connected to an air-filled hollow space formed by the cylinder and the piston. The force of pressure from the piston's connected cabinet/furniture component compresses the air found in the hollow space and notch of the piston which results in a radial expansion of the piston. Braking action results from the stretching or expanding of the piston diameter, which additionally occurs with the above-described damping action resulting from the air compression.

Patent CA-2224066-A1 (CA)
Title: Peptides as analgesics
Inventor: LEMAIRE SIMON
IPC: C07K5/12
Filed: 1998-02-24
Abstract: No effective remedy exists for the treatment of chronic pain resulting from inflammation and neuropathy. The adrenal medullary peptide, histogranin (HN), and its chemically stable analogue, [Ser1]HN, alleviate the same type of pain as that blocked by spinal adrenal medullary implants.          However, the administration of these peptides is more advantageous than the transplantation of adrenal medullary tissues or chromaffin cells into the spinal cord. In addition, the structure of HN peptides can be modified to improve their efficacy and length of action while avoiding the side-effects of opioid analgesics, aspirin derivatives and non-steroidal antiinflammatory agents.  The HN fragment-(7-10), Gly-Gln-Gly-Arg (SL-99), is an analgesic as potent as the parent peptide HN in the mouse writhing pain assay.  Its analogues,  [Ala9]HN-(7-10) (SL-100: Gly-Gln-Ala-Arg) and [Arg7, Ala9]HN-(7-10) (SL-101: Arg-Gln-Ala-Arg), cyclo-(SL-100)  (or SL-102) and the parent peptide [Ser1, Ala9]HN (SL-104: Met-Asn-Tyr-Ala-Leu-Lys-Gly-Gln-Ala-Arg-Thr-Leu-Tyr-Gly-Phe), show improved potency as compared with HN.  The linear and cyclic forms of SL-100 and SL-101 are presented with the following general Formulae:     (see fig. I)                (see fig. II) wherein R1, R2, R3, R4, R5 and R6 are H (SL-100) or (CH2)2-NH2 (SL-101), (CH2)3-NH-C(=NH)-NH2,  CH3,   (CH2)2-NH2 H and H, respectively, or related substituents.  The pharmaceutically-acceptable salts, esters and amides comprised in formulae I and II compounds, which are useful for inducing analgesia in animals, and a method for inducing analgesia in an animal in need thereof comprising administering a therapeutically-effective amount of Formula I or Formula II compounds to the animal.

The superplasticizers have a carbon backbone formed by polymerization of ethylenically-unsaturated carboxylic acids, the backbone comprising carboxylic acid grafting sites to which are covalently attached a) air detraining functional side chains, which are first polyoxyalkylene groups of the general formula: R4-(OA2)x-Q-, wherein Q = O or NH; A2 = C1-C10alkylene; x = 1 to 200; and R4 = C1-C10alkyl, and b) second polyoxyalkylene groups of the general formula R5-O-(A3O)y-(A3)p-N=, wherein A3 = C1-C10alkylene; y = 1 to 200; p = 1 to 50; and R5 = C1-C10alkyl.
Patent CA-2227158-A1 (CA)
Inventor: BOUDREAULT JEAN-PIERRE
IPC: F24C15/20
Filed: 1998-01-12
Abstract: The exhaust hood assembly has a vertically disposed greast extractor which leads into a suction ventilator adapted for expelling air and odor to the outside. The assembly has a first deflector at the entrance into the grease extractor to cause a first swirl of the air loaded with grease, impurities and odors, and a first release thereof into a bucket provided below the greast extractor. Inside the greast extractor there are two deflectors to cause swirls of the air load with grease and odor and release of grease and particles into the bucket. Finally, any grease and/or impurities not released in the grease extractor are centrifugally expelled by the suction ventilator and sent through a tube which also feeds into the bucket. This device is inexpensive to produce and is much more efficient than those currently in use.
Patent CA-2228156-A1 (CA)
Title: Rolling cone bit with enhancements in cutter element placement and materials to optimize borehole corner cutting duty
Inventor: PORTWOOD GARY RAY
IPC: E21B10/52
Filed: 1997-04-10
Abstract: A rolling cone bit (10) includes a cone cutter (14, 15, 16) having a pair of adjacent rows of cutter elements (70, 80) that are positioned so as to divide the sidewall (5) and bottom hole (7) duty. The wear resistance, hardness and toughness of the cutter elements (70, 80) in the adjacent rows are optimized depending upon the type of cutting the respective rows perform. In most applications, the cutter elements (70) experiencing the sidewall cutting will have cutting surfaces that are more resistant or harder than the cutting surfaces of the cutter elements (80) in the rows experiencing more bottom hole duty. Likewise, the cutter elements (80) exposed to the bottom hole duty will generally be tougher than those (70) experiencing substantial sidewall cutting. The material enhancements include varying the grades of tungsten carbide used in the cutter elements (70, 80) and by selectively employing layers of superhard abrasives, such as PCD or PCBN. The cutter elements (70, 80) may be either inserts or steel teeth.
Patent CA-2229147-A1 (CA)
Title: Method of motion estimation for image sequences, in particular for video signal processing
Inventor: CUCCHI SILVIO
IPC: H04N7/26
Filed: 1998-03-10
Abstract: A method is described for estimating the motion for image sequences carrying out a decimation of the function used for the extraction of the characteristic parameters of an image block. The method is iterated by decreasing the function decimation and carrying out the block-matching on a set of the best matchings of the preceding steps. The method does not require the recalculation of the parameters on the referenceimage for each block to be matched; moreover, in the extraction of the characteristic parameters of a block, the use of the Integral Projections is notmandatory but one of the possible variants only (Fig. 1).
