Patent CA-2200047-C (CA)
Inventor: BOMHOLT JOHN
IPC: G01G19/38
Filed: 1995-09-15
Granted: 2005-10-11
Abstract: A batching of currently supplied articles with non-uniform weights into portions of a uniform target weight is effected by passing the articles through a weighing station (6, 8) to a distribution system (12), in which the articles (4) are selectively allocated to a plurality of receiver bins (14). It is known to improve the capacity of such a system by way of probability calculations based on the normal distribution of the articles in the supply flow, but according to the invention it is still better to base such calculations on a regularly updated recorded histogram (28) of the weight distribution of a relatively high number of newly weighed articles. Thereby the target calculations will rely on factual rather than just expected conditions, and a very important result is that it is possible to effect relevant batching even when the article weights in the supply flow are not normally distributed.

Abstract: A stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) deforming the metal pattern so as to cause two opposing sides to meet, and c) joining the two opposing sides at least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel.

Abstract: A module support structure 1 is proposed for printed circuit boards 2 which can be inserted on guide rails 5. The four parallel module rails 4 of the module support structure 1 to which the guide rails 5 are mounted are connected to the two parallel side walls 3 via a special mounting technique. Specially shaped mounting bolts 8 are used consisting essentially of a bolt head 11 having a flat seating surface 13, a substantially cylindrical threaded shaft 12, as well as a transition piece 19 disposed between the bolt head 11 and the threaded shaft 12 and tapering in a conical manner towards the threaded shaft 12. The mounting bolts 8 are fed through cylindrical mounting holes 9 in the side walls 3 and screwed into cylindrical holes 10 in the module rails 4. During tightening, the transition piece 19 abuts against the outer edge of the mounting holes 9 to force the module rails 4 against the projections 17 disposed above or below the mounting holes 9. In this manner, an exact positioning of the module rails 4 relative to the side walls 3 is necessarily effected. The outer edge of each mounting hole 9 can be deformed by the transition piece 19 until the seating surface 13 of the corresponding bolt head 11 seats on the side wall 3.

Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated magnetically permeable member mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated magnetically permeable member which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated magnetically permeable member of the armature extends. A radially enlarged slug on the free end of the elongated magnetically permeable member of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits.

Title: Tapered waveguide for optical dispersion compensation
Inventor: DELISLE VINCENT
IPC: G02B6/122

Granted: 2006-04-04
Abstract: An optical device for creating chromatic dispersion which comprises an input receiving an optic communications signal, a first waveguide, a second waveguide and an output for outputting the optic communications signal with modified chromatic dispersion characteristics. The first waveguide has a first index of refraction and a lateral coupling surface and is able to guide a mode of light. It has a substantially uniform thickness. The second waveguide has a second index of refraction significantly different from the first index of refraction and a corresponding lateral coupling surface coupled to the lateral surface of the first waveguide. It also has a variable thickness selected to allow a predetermined wavelength to couple massively from the first to the second waveguide at a predetermined distance along the coupling surface in the direction of propagation of the mode of light, the thickness varying gradually in the direction of propagation of light so as to allow neighboring wavelength components of an optical signal to undergo chromatic dispersion by coupling from the first waveguide to the second waveguide at different positions.

Abstract: The present invention provides a process for the recovery of base metal sulfides including chalcocite, chalcopyrite, pentlandite and platinum group metal bearing mineral ores. The process involves passing a slurry of the ore through a reagent conditioning stage wherein suitable activators, collectors, frothers and/or depressants are added, further conditioning the slurry with a non-oxidizing gas in a quantity conducive to the separation of the sulfide minerals from the remainder of the ore and subsequently subjecting the slurry to a final flotation treatment with a flotation gas having a higher oxygen content than the non-oxidizing gas. The non-oxidizing gas conditioning can be carried out prior to or after the reagent conditioning stage.
