Title: Sulphur reducing bacterium and its use in biological desulphurisation processes
Inventor: STETTER KARL OTTO
IPC: C12N1/20
Filed: 1997-07-16
Abstract: A new sulphur-reducing bacterium denoted as KT7 is described. It is a low-GC  Gram-positive bacterium related to the genus Desulfoto-maculum, capable of reducing sulphite and sulphate to sulphide, having an optimum growth at a temperature between 48 and 70 ~C, at a pH of between 5 and 9 and at a conductivity of the liquid medium between 0 and 40 mS/cm. It can be used in a process for removing sulphur compounds from water, wherein the sulphur-containing water is subjected to anaerobic treatment with the new sulphur-reducing bacteria, with the addition of an electron donor. The sulphur-containing water can be spent scrubbing liquid from a flue gas desulphurisation step.

Title: Permanent magnet direct current (pmdc) machine with integral reconfigurable winding control
Inventor: RIVERA NICHOLAS N
IPC: H02P6/08
Filed: 1997-08-15
Abstract: This PMDC machine concept operates from a constant dc voltage source (30) with maximum torque capacity throughout its rotational speed range. The back electromotive force (back-emf) produced by the machine windings (21) under the constant amplitude air gap (12) field produced by the magnets (15) is controlled by changing the winding configurations in series-parallel combinations (Figs. 3A and 3B). Torque is, thus, controlled from minimum to maximum speed without exceeding winding current capacities and without need to increase driving voltage with speed. A startup and low speed the combined back-emf of series connected windings (21) limit current while producing maximum torque. At higher speeds where back-emf would severely limit torque, the windings are connected in series-parallel combinations for maximum achievable torque without exceeding winding current capacities. To accomplish this, windings (21) concentrated in slots (17) are used. Result is optimum utilization of core magnetics and capability of operating at constant input voltage.

Title: Golf club restraint arm & support stand
Inventor: KIRBY DANIEL L
IPC: A63B69/00
Filed: 1999-03-12
Abstract: The Golf Club Restraint Arm & Support Stand, is designed to help golfers to hit straighter golf shots. The structured restraint arm comprises an elbow with an enlarged opening at one end to receive the fast section of the horizontal cross-bar.  This enlarged opening end is to receive the first section of the horizontal cross-bar which is eleven inches in length. A three way fitting or a T-fitting is then inserted into the first section of the horizontal cross-bar, which is eleven inches in length. At this juncture, the other two fittings will receive a vertical post and the second and final part of the horizontal arm which is thirteen inches in length. The over-all length of this cross-bar when it is inserted to the enlarged opening of the elbow is twenty-five inches in length The section where the vertical post and the second section of the cross-bar join at the T-fitting, creates a 45 degree angle. It is this 45 degree angle that acts as the restraint arm. This section of the restraint arm, restricts the golf club and golf swing from going beyond the waist high to waist high exercise, which is its intended purpose to hitting straighter golf shots. THIS    IS THE CRUX OF THE INVENTION. This 45 degree angle prevents the golfer club and his swing from going in any swing direction except straight. The thirteen inch horizontal cross-bar that is joined with the vertical post by the T-fitting are both foam insulated to prevent any golf chit breakage or bending during the swinging motion or drill of the exercise. Inserted at the ends of the vertical post and horizontal cross-bar that form the 45 degree angle are plugs for aesthetic purposes. In order for the Golf Club Restraint Arm to be functional it must have a support stand.

Title: Improved leaching of mineral ores
Inventor: NGUYEN GIAO
IPC: C22B3/04
Filed: 1997-11-06
Abstract: A process for oxidation of ferrous ions in solution, and more particularly a process for improved base metal and/or uranium leaching from ores, concentrates or tailings using ferric ion as an oxidising agent. A reaction vessel (10) holds a ferrous ion-containing solution, for example, a copper sulphide leach slurry or concentrate. An agitator (12) may be provided to promote leaching of the base metal into solu-tion. Some of the ferrous ion-containing solu-tion is drawn off from the reaction vessel (10) and pumped through an in-line mixer (14) via a feed pump (16). Oxygen is injected into the reactor (14) to facilitate oxidation of the fer-rous sulphate to form ferric sulphate. The fer-ric ion-containing solution is then recirculated back to the reaction vessel (10) where the fer-ric ions arc reused in the dissolution of copper sulphide into soluble copper sulphate. The two processes of ferrous oxidation and metal leach-ing can be conducted either simultaneously or sequentially to effect recovery of copper, other base metals or uranium from ores, concentrates or tailings.

This approach integrates the advantages of format-specific compression into a general-purpose compression tool serving a wide range of data formats. Source data is parsed into blocks of similar data and each parsed blocks are compressed using a respectively selected compression algorithm. The algorithm can be chosen from a static model of the data or can be adaptive to the data in the parsed block. The parsed blocks are then combined into an encoded data file. For decoding, the process is reversed.

Patent CA-2287797-A1 (CA)
Inventor: PLATTS ROBERT E
IPC: E04H9/14
Filed: 1999-10-12
Abstract: This invention comprises ways and means of strengthening roofs to withstand hurricane winds using widely spaced anchor assemblies consisting of clasps and tension members to hold down the overhanging eave portion of the roof to strong anchors in existing structural members in the wall below. The wide spacing exploits the roof's bending strength and folded plate action along its length (in the direction across the framing members in the roof plane); the invention includes means of reinforcing that strength by means of beams where suitably strong anchorage points occur too far apart. Alternatively, the invention includes means of strengthening a framed wall to receive and secure anchors where no framing exists at the desired point. The invention minimizes disruption of building and occupants, entailing little make-good, and the number of anchor assemblies, all serving to minimize costs. Where the underside of the eave is not closed in, ie. there's no soffit closure, then "U" clasps grip certain of the protruding rafters or truss extensions and are tied to the wall anchors. An alternative yoke type of clasp is described. Where the roof overhang is itself too weak against wind uplift the clasp points can be located suitably outboard of the exterior wall, toward the fascia, thereby reducing the cantilever span of the overhang while also tying down the roof proper. Where, on the other hand, soffit closures prevent access to the rafters, flanged clasps are fixed to the fascia and edge portions of the roof and tied to the wall anchors. That also strengthens the overhangs, effectively removing their cantilever condition. The wall anchors are inserted into window or door bucks or frames or wall junctions to exploit the embedded load-spreader capability presented by such frames and junctions. Preferred materials for the anchorage assemblies are non-corrosive steels, which may be blackened or otherwise coloured for appearance.
