Title: Magnetic removal of "stickies" from waste papers
Inventor: MARWAH NIPUN
IPC: D21D5/00
Filed: 1997-04-04
Abstract: An  improved  process  is  disclosed  for  removing "stickies" from waste paper which contains hot-melt and pressure-sensitive adhesives and lattices to produce high quality (high brightness, little to no dirt content) pulp with  little  or  no  fiber  loss.    The  process  involves attachment of sticky particles in the waste paper pulp to a  magnetic  carrier  material  with  the  help  of  an agglomeration agent followed by removal of the attached sticky particles by magnetic separation.   The magnetic treatment preferably is conducted at ambient or greater temperature, at neutral to alkaline pH and at a low pulp consistency.     Agglomeration  and  magnetite  addition, followed by exposure of the repulped waste paper to a magnetic field provides near complete sticky removal over exposure to the magnetic field without such pre-treatment.

Patent CA-2234004-A1 (CA)
Inventor: GITNES SETH E
IPC: F16D43/206
Filed: 1998-04-06
Abstract: The torque limiter described herein is a device for preventing the transmission of torque from a drive source to a torque responsive element when a predetermined torque limit has been reached. The device also provides subsequent mechanical indication of said torque overload event. The device operates by transmitting torque between two axial members, a drive member and a driven member, having a plurality of balls therebetween with the balls engaged within precisely shaped sockets contained within each axial member. As excess torque occurs, the plurality of balls cause the driven member to axially displace with respect to the drive member, engaging a set of teeth contained on the driven member with a second set of teeth aligned with the first set of teeth and restrained within the housing, thereby preventing torque transmission. The second set of teeth is allowed to rotate, relative to the housing, through a predetermined angle into a torsionally compliant mount before contacting substantially rigid structure. This allows the teeth to engage smoothly at higher operating speeds. Indication of the torque overload event is achieved by detecting the limited motion of the second set of teeth relative to the housing with a slidably mounted plunger within the housing and axially located by a detent in the member containing the second set of teeth.

Title: Image sequence coding method and decoding method
Inventor: NAKAYA YUICHIRO
IPC: H04N19/593
Filed: 1998-06-08
Abstract: In order to prevent accumulation of rounding errors caused by the integer-based bilinear interpolation used in the motion compensation process of image coding and decoding methods, two types of P frames are used for unidirectional motion compensation prediction; P+ frames, which round the results of bilinear interpolation with real number operations to the nearest integer and rounds half integer values (0. 5 added to an integer) away from zero; and P- framed, which differs from P+ frames in that the above mentioned half integer values are rounded towards zero. Utilizing both of these P+ and P- frames enables canceling of rounding errors and prevents the accumulation of rounding errors.

IPC: C22B15/00
Filed: 1998-06-19
Abstract: Thiobacillus ferrooxidans and Thiobacillus thiooxidans play major roles in bacterial leaching of metals from ores and tailings through their oxidative action on ferrous iron (Fe2+) and sulfide or sulfur (S0). We have studied the effects of various inhibitors such as cyanide, azide and anions (phosphate, nitrate, chloride) on Fe2+ or S0 oxidation by resting cells, on Fe2+ or S0 as an energy source for growth and finally on leaching of Fe or Zn from a sample containing pyrite (FeS2) and sphalerite (ZnS). All of these inhibitors inhibited Fe2+ oxidation more strongly than S0 oxidation and generally stopped the growth on Fe2+ at lower concentrations than on S0. All three anions inhibited the leaching of Fe more strongly than Zn leaching, but potassium phosphate was the most selective. In the leaching experiments with T.  ferrooxidans and T. thiooxidans either singly or combined, phosphate at 10 - 100 mM reduced the Fe leaching almost completely (by 90 - over 95%) without affecting the Zn leaching (0 - 40%).

Title: Trenchless underground boring system with boring tool location
Inventor: ALLEN CHRISTOPHER T
IPC: E21B47/12
Filed: 1996-12-20
Abstract: An apparatus and method for locating an underground boring tool using a radar-like probe and detection technique. A boring tool is provided with a device which generates a specific signature signal in response to a probe signal transmitted from above the ground. Cooperative operation between the probe signal transmitter at ground level and a signature signal generator disposed within the boring tool provides for the accurate locating of the boring tool, despite the presence of a large background signal. The signature signal produced by the boring tool may be generated either passively or actively, and in a manner which differs from the probe signal in one or more ways, including timing, frequency content, or polarization. A survey of a boring site, made either prior to or during the boring operation, provides data related to the characteristics of the ground medium subjected to the survey and the identification of underground hazards, such as buried utilities.
