Patent CA-2095697-C (CA)
Title: Elastomeric sealing system for architectural joints
Inventor: NICHOLAS JOHN D
IPC: E04B1/68
Filed: 1993-05-06
Granted: 1995-08-15
Abstract: An   elastomeric   seal   for  connecting  two relatively movable architectural structures, such as floor sections, is constructed to optimize resistance to failure of the elastomeric element, in either adhesion or cohesion modes.   An elastomeric seal,  and an underlying support plate  are  provided  with  gently  undulating,  somewhat sinusoidal  surface  configuration,  with the  elastomeric element being of downwardly convex configuration and of relatively  maximum  thickness  in  its  center,  and  of downwardly  concave  configuration  and  relatively  less thickness in regions spaced on either side of center.          Widthwise stretching of the elastomeric element tends to be concentrated  in  the  regions  of  downwardly  concave configuration, being thus not only distributed but also located away from areas of maximum vertical stress.   An underlying supporting plate is provided with relatively thin, deformable edge flanges, which enable the supporting plate to function as a mold bottom,  for pouring of a curable liquid elastomer at a nominal width, while at the same time allowing lateral compression of the assembly to a lesser width during normal functioning of the sealing system.

Abstract: A skate blade finishing tool includes a holder adapted to be hand-held by a user.  The holder includes at least one slot therein.  Arranged in the slot is a strip of leather.  In use, the leather strip in the slot is rubbed along the length of a sharpened skate blade in a predetermined number of passes.  The leather strip removes foreign material redeposited by skate sharpening processes and small burrs remaining on the blade surface and smooths the skate blade surfaces.  When using the skate blade finishing tool to finish a skate blade, the detrimental effects of the sharpening process are removed to  provide  a  safe  skating  blade  that also  permits improved skating performance when using the finished blade.

Abstract: In an integrated circuit system, a filter and an oscillator are referenced to a common reference circuitry.through a suitable control loop to provide filter time constant and oscillator frequency references. The oscillator (Fig. 3) and the filter (Fig. 4) are implemented in a manner where the monolithic pattern elements setting the fundamental control parameters (time-period and time-constant respectively) are of the same type. Monolithic capacitors are used as one of the common passive elements between the oscillator and the filter to set the time-period and time-constants, respectively, adjustable through adjustment of control currents (losc; Ix). The monolithic implementation of the Control Block (Fig. 3, Fig. 4 and Fig. 7) is such that by tuning the oscillator frequency to he appropriate value through setting of the respective control current (losc), the filter time-constants also are appropriately set to satisfy the Nyquist criteria for a sampling rate referenced to the oscillator frequency.

Abstract: An orally administrable therapeutic protein is provided by combining the therapeutic protein with a stabilizing agent in an aqueous solution. The solution is coated onto a nonpareil and microencapsulated with a water emulsifiable enteric coating composition. The microcapsules are orally administered. The coating protects the protein as it passes through the stomach. Upon reaching the small intestines, the basic pH of the intestinal juices will dissolve the coating allowing the protein to be released. The stabilizing agent will protect the therapeutic protein during the encapsulation process and inhibit proteolytic enzymes in the small intestines thereby allowing the therapeutic protein to reach lymphoid tissue in the small intestines.

Abstract: Disclosed herein is a single step sterilization wrapping material suitable for use, as an example, in wrapping surgical instruments and supplies for sterilization, transportation and storage. The material includes separate inner and outer wraps which, unlike previous wraps, are joined to one another.     Common wrapping techniques involve wrapping items to be sterilized with two separate sheets of wrap. The present invention provides separate wraps which can be specially engineered to deliver specific properties for each sheet and then joined to one another so as to permit wrapping and opening in a neat single step process which increases efficiency and saves time and money. In special situations the outer wrap can be engineered with increased strength, the inner wrap with increased barrier properties and the inner and outer wraps can be made visually distinct from one another so that improper wrapping or opening is not a problem.

Granted: 1998-06-30
Abstract: Disclosed is a system for regulating the efficiency of a combustion process by d etecting radiant energy emitted from ash particles entrained in the gas stream exiting the combustion chamber of a boiler or incinerator. The intensity of selected wave-lengths of light emitted from the particles is indicative of the temperatur e of the particles. The change in the intensities of the selected wavelengths of light, and thus of the temperature of the gas stream at the furnace exit, is monitored, and a feedback control mechanism is used to regulate one or more combustion, pollution control, or heat transfer parameters thereby maximizing the thermal efficiency of the combustion process in the boiler or incinerator.

Abstract: This invention is directed to a multipurpose repair and maintenance apparatus for aerial inspection, repair and cleaning, comprising a work platform for installation on the skids of an helicopter and sustaining a boom assembly and a fluid circuit such that the loads on the work platform are fully balanced. The work platform is made of electrically conductive material and all electrically conductive parts of the apparatus are connected to the electrically conductive parts of the helicopter to have same electrical potential. The boom assembly extends from the port side of the work platform and has an inboard section and an outboard section. The pumping means are mounted on a power drive mount at the starboard side of the platform, so as to balance the weight of the boom assembly. Boom actuating means are provided at the onboard end of the boom assembly for controlling the vertical and horizontal movement of the outboard end. The fluid circuit include pumping means and fluid conduits guided along the boom assembly for spraying cleaning fluid from a fluid storage tank through a nozzle located at the outboard end of the boom assembly. The orientation of the nozzle is controlled with a nozzle control ann. When the work platform is used for inspection or repair, the boom assembly is removed and a wing is attached to the portside.  Now, the weight of the inspector/repairman at the portside is balanced by the weight of the power drive mount at the starboard side. In addition, the length of the starboard side of the work platform and the port side is also selected so that the loads are balanced.

Title: Golf club with lockable head-to-shaft angle adjustment
Inventor: HANNON RICHARD H
IPC: A63B53/06
Filed: 1994-10-31
Granted: 1997-06-17
Abstract: A golf club having a mechanism permitting adjustment of the shaft angle relative to the club head.  Fixed stops limit the range of angular adjustment.  The body of the club head has a central opening extending to the sole of the club.  The opening is closed by a sole plate that requires a special tool for removal and reinstallation.  A serrated surface secured to an extension of the club shaft within the opening mates with a corresponding serrated surface secured to the club head.  The angle of the shaft relative to the head is locked by installing the sole plate which forces the two serrated surfaces together. In order to change the shaft-to-head angle, the sole plate must be loosened sufficiently to permit the cooperating serrations to disengage and be moved relative to each other.

Abstract: Amorphous boric oxide - containing product having about 85 to 92% by weight B2O3 is produced by heating boric acid at an elevated temperature of up to about 275°C to dehydrate the boric acid and form a molten glass which is cooled to a solid glassy product. This solid glass can be comminuted to produce a particulate product. Preferably the boric acid is heated at 220° to 275°C, with about 250° to 270°C being most preferred. The process is readily adapted to a continuous process in which the boric acid is placed on a moving continuous steel belt and conveyed through a heating zone. The molten glassy product is cooled to form a solid glassy product which is removed from the belt and comminuted to a desirable particle size range.
