Patent CA-2043800-A1 (CA)
Title: Joining device
Inventor: MONETTE ANDRE
IPC: E04H17/14
Filed: 1991-06-03
Abstract: A  joining device  comprises  a  cylindrical bar with a projecting pin at one end and two rigid bodies having cylindrical holes and channels for accomodating the bar and the pin.   The two rigid bodies are first attached to elements to be joined.  Insertion of the bar into the holes and subsequent rotation of the bar causes the two bodies and thus  the two elements  to be retained together.   In a preferred case, the two elements are urged together because the far edge of the second body to be entered has a sloping edge which is a cam surface against the projecting pin.  The joining device may be used in fencing particularly for surrounding temporary winter rinks.  Erection and disassembly of such rinks is thus hastened.

Patent CA-2046108-A1 (CA)
Inventor: SMALL JAMES G
IPC: G01F1/28
Filed: 1991-07-03
Abstract: OPTOELECTRONIC MOTION AND FLUID FLOW SENSOR          ABSTRACT OF THE DISCLOSURE     A sensor includes a-light source (24) and photosensor (28) which are disposed on opposite sides of a fluid flow passageway.  A resilient member is fixedly supported at one end or edge and entrained in the fluid (14) for varying the amount of light incident on the photosensor (28) from the light source (24) as a function of the amount of deflection of the resilient member caused by motion of the fluid (14) in the passageway.  The resilient member may be an optical fiber (18) which transmits light from the light source (24) toward the photosensor (28).  Alternatively, the resilient member may be a curtain (62) which variably blocks propaga-tion of light from the light source (24) to the photosensor (28).  The passageway may be defined by a container (12) which  is  filled with the  fluid  (14),  and the  sensor constructed to sense rotational or linear motion of the container (12) relative to the fluid (14).  In this case, the  fluid resists movement due to  stationary inertia, thereby  causing  relative  deflection  of  the  entrained resilient member.   Alternatively, the passageway may be maintained  stationary,  and  a  fluid  directed  to  flow therethrough which  causes  deflection  of  the  resilient member and enables measurement of the rate of fluid flow through the passageway.

Title: Anti-abrasive partition, a shipping container formed therewith and methods
Inventor: BOUWENS BRIAN E
IPC: B65D81/02
Filed: 1991-10-16
Abstract: AN ANTI-ABRASIVE PARTITION, A SHIPPING CONTAINER FORMED THEREWITH AND METHODS          Abstract of the Disclosure Novel anti-abrasive partitions comprising facing webs of spunbonded olefin fabrics, such as spunbonded polypropylene fabrics, affixed to reinforcing substrates, such as paperboard, linerboard or chipboard, are disclosed.  The novel anti-abrasive partitions are suitable for forming anti-abrasive partition assemblies for use with shipping containers.          Because the novel partitions are anti-abrasive, they are especially suited for packaging and shipping highly polished or abrasion-sensitive articles, such as automotive and appliance high gloss black water cosmetic finish parts.  Moreover, because the novel anti-abrasive partitions do not shed particulate matter during packaging and shipment, the articles packaged in containers having such anti-abrasive partitions do not have to be subsequently wiped down by hand to remove contamination caused by particulate residue migrating therefrom.

Title: Method of working coal seams to a defined preset depth of cutting during ploughing with a cutter
Inventor: GEUNS GUY
IPC: E21C27/32
Filed: 1992-05-28
Abstract: ABSTRACT OF THE DISCLOSURE       A method of working coal seams to a defined preset cutting depth during ploughing with  a cutter,  a  face conveyor moving  along a  face behind the  cutter being advanced by the defined preset cutting depth and this advance being made by extension of self-advancing cylinders pivotally attached at one end to the face conveyor and at the other end to face supports disposed parallel to the face conveyor.   The advance is controlled in dependence upon the piston stroke of the self-advancing cylinders, carried out in dependence upon individually defined partial strokes  corresponding to the preset depth of cutting.          After a predetermined maximum total piston stroke has been reached,  the  face  support connected to the respective self-advancing  cylinder  is automatically  disengaged, advanced by the maximum total piston stroke and then re-set (self-advancing process).   The  length of  the partial strokes corresponding to the preset depth of cutting is increased by an amount to compensate an average mechanical clearance  at  the pivot points  of the  self-advancing cylinders.

Patent CA-2076303-A1 (CA)
Title: Animal shelter flooring apparatus
Inventor: RAHM LARRY
IPC: A01K1/015
Filed: 1992-08-18
Abstract: ABSTRACT    Flooring  for  an  animal  shelter  uses inwardly sloping wedge shaped flooring members held in a spaced apart parallel relationship by wedge shaped center spacers and end spacers having an outward slope.  These wedge shapes match such that when the inclined surfaces of the spacers and the flooring members adjoin each other the flooring members will hold the spacers in place.  The flooring members ends also incline inward so that a pair of aligned flooring  members  with  their  ends  abutting enclose a triangular shaped space.   A rod extending through the inclined surfaces of the center spacer is arranged to extend into this space when the inclined surfaces of the center spacer and the two flooring member adjoin.          This rod prevents the center spacer from moving longitudinally along the flooring members.  An end spacer with similar inclined sides has a bar extending across an end perpendicular to the inclined sides.  This bar will also prevent the end spacer from moving longitudinally along the flooring members when flooring members are placed on opposite sides of the end spacer with the  inclined  surfaces  adjoining,  the  ends aligned, and the bar located on the outside.          The flooring members are assembled on site within a supporting structure such that the flooring members are parallel,  with center spacers being placed between the adjacent ends of the flooring members where the ends of two flooring members abut, and end spacers being placed  between  the  adjacent  ends  of  the flooring members where the flooring terminates.

Title: Ratcheted pedal mechanism for an exercising apparatus
Inventor: ROBERT ANDRE
IPC: B62M3/00
Filed: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE              A pedal mechanism for exercising apparatus comprises  a  drive  axle  rotatably  mounted  on  the exercising apparatus.   The drive axle has left and right ends constituting pivotal connections on which the corresponding proximate ends of left and right cranks are mounted.  A left pedal, mounted rotatable on the distal end of the left crank is provided with a system for attaching the left foot of a user person thereto.   A right pedal, mounted rotatable on the distal end of the right crank is provided with the same system for attaching the right foot of the user person thereto.  Left and right ratchet mechanisms are interposed between the respective proximate ends of the left and right cranks and the corresponding left and  right  ends  of  the  drive  axle.    The  ratchet mechanisms  allow  the  transmission  of  rotational movement from the left or the right crank to the drive axle in one direction while leaving the left or the right crank free to rotate in an opposite direction to the  drive  axle.   Accordingly,  during use of the exercising apparatus, to achieve rotation of either the left or the right crank in one direction, the user person must apply force to the corresponding left or right pedal over 360° for each complete revolution of the pedals.
