Patent CA-2309910-A1 (CA)
Inventor: VISSCHER RONALD BOSMAN
IPC: A61F13/64
Filed: 1998-11-09
Abstract: The present invention relates to undergarment that have close body fit. The undergarment of the present invention includes an elasticized waistband, a front region, a rear region, a crotch region and a pair of elasticized leg openings. The front and rear regions are preferably elastically extensible in both the longitudinal and lateral direction. The crutch region is disposed between the front and rear regions and has greater resistance to scratching in the longitudinal direction than the front and rear regions. The crotch region is further provided with a longitudinal stretch control member that is disposed along the longitudinal centerline of the undergarment and a plurality of angled stretch control members that extend from the longitudinal stretch control member to the leg elastics at an acute angle to the longitudinal stretch control member. The stretch control members limit the stretch of the crotch region in both the longitudinal and the lateral directions that causes the crotch region to conform to a wearer's skin surface. The rear region is provided with a lifting member that cooperates with tire rear region, the front region and the longitudinal stretch control member to provide a "z-direction" biasing force along the longitudinal stretch control member. This biasing force, which is greater than the body contact force is adjacent portions of the crotch region, causes the crotch region, and any absorbent article that may be disposed thereon, to be lifted into close ~odily contact when the undergarment is worm.

Filed: 1998-12-07
Abstract: The invention is directed to a method for sterilizng a pharmaceutical formulation comprising a suspension of a water-insoluble pharmaceutical, comprising the steps of heat-sterilizing an aqueous solution of a viscosity enhancer, to result in a first sterile premix. Next is sterile-filtering an aqueous solution of a mixture of a pharmaceutically-active compound, which results in a second sterile pre-mix. Next is heat-sterilizing a mixture of water, a water-insoluble pharmaceutical, and at least a partial amount of an electrolyte to provide a sub-saturated solution of the electrolyte, and adding under aseptic conditions an aqueous surfactant, to give a third sterile pre-mix. Finally, combining all three pre-mixes in sterile fashion to achieve a sterile suspended pharmaceutical formulation. Thus, for the third pre-mix, use of either Sodium chloride (in varying proportion) or Sodium acetate (in one proportion, but not limited to) is given as an example. The invention is also directed to methods for making sterile suspensions of pharmaceutically active compositions including Ciprofloxacin and hydrocortisone, and pharmaceutical compositions made according to this process.

Title: Spiral for interconnecting ends of endless belt segments
Inventor: CORRIVEAU ANDRE
IPC: F16G3/02
Filed: 2000-06-16
Abstract: A spiral for interconnecting ends of endless belt segments using a pintle. The spiral comprises a series of loops including inverted U-shaped loop portions extending in a transverse direction of the spiral. The loop portions have front and rear legs spaced apart from each other for passage of the pintle therebetween. U-shaped loop linking portions extend diagonally with respect to a longitudinal direction of the spiral, between lower ends of the front legs and lower ends of the rear legs of the next loop portions respectively. The loop portions are spaced from one another by a distance corresponding to a width of the legs of the loop portions in the longitudinal direction of the spiral, thereby defining openings for interdigitation with a like spiral to form a channel for the pintle.

Title: Interprocedural dead store elimination
Inventor: ARCHAMBAULT ROCH GEORGES
IPC: G06F9/45
Filed: 2000-09-27
Abstract: A system for optimizing computer code generation by carrying out interprocedural dead store elimination. The system carries out a top down traversal of a call graph in an intermediate representation of the code being compiled. Live on exit (LOE) sets are defined for variables at call points for functions in the code being compiled. Bit vectors representing the LOE sets for call points for functions are stored in an LOE table indexed or hashed by call graph edges. For each function definition reached in the call graph traversal, a LOE set for the function itself is generated by taking the union of the LOE call point sets. The entries in the LOE table for the LOE  call point sets are then removed. The LOE set for each function is used to determine if variables that are the subject of a store operation in a function may be subject to a dead store elimination optimization.

Title: Traction tread
Inventor: JACOBS PETER
IPC: E04F11/16
Filed: 2001-02-06
Abstract: The following describes my invention for a custom manufactured stair tread cover which, when placed over an existing stair tread of any substrate materials improves the anti slip factor of the stair tread resulting in increased safety and increased stair life. The components of this invention consists of a custom bent metal base, coated with an aggregate embodied in an epoxy coating which increases surface traction creating a non slip, cleanable and durable surface covering. The new "Traction tread" is designed to be replaceable when worn-out, without damage or epoxy build up to the existing stair(s) tread. Installation will differ due to different substrate materials used in the construction of the existing stair tread. The traction tread is superior to existing methods as the traction tread overcomes environmental and down time issues as outlined in the attached description. They are fabricated to fit securely over the existing step. The traction tread has a return flange which accommodates the nail, screw or other fastening device required to attach the unit to the existing stair tread.

Patent CA-2335388-A1 (CA)
Inventor: MASTCHENKO ALAIN
IPC: E04B1/70
Filed: 1998-02-27
Abstract: The invention concerns a method for controlling and regulating water quantity in a medium which consists in applying a pulsed unidirectional electric field between one or two electrodes inserted in the treated medium with sequential inversion of the generator polarities, whereby a unidirectional potential difference is established by selecting said field orientation by inversion of the generator polarities to modify the direction of the water draining, the aim being to humidify or drain the treated medium. The electrode can consist of a metallic part already present in the medium. The moisture measuring probes and the treating electrodes are inserted in the medium and connected to the electronic power unit which regulates the predetermined water quantity and maintains it by controlling the operation of the generator. The arrangement of the electrodes and moisture measuring probes is related to the medium and the desired result. The electronic power unit regulates the intensity and voltage depending on different media, influential circumstances or modifications occurring therein. The invention is particularly applicable and efficient in agriculture and the building industry.
