Title: Detent lock mechanism for pin-and-sleeve heavy duty electrical connector
Inventor: ANGIOLILLO LUCIO
IPC: H01R13/53
Filed: 2000-03-14
Abstract: An electrical receptacle includes a receptacle housing, a movable element, an interlock mechanism, a release mechanism, and a blocking element. The receptacle housing has a receptacle opening having a longitudinal axis.      The movable element is located within the receptacle opening and is designed to move along the longitudinal axis between an extended position and an inserted position. The interlock mechanism is connected to interlock with the movable element when the movable element is in the inserted position. The interlock mechanism also maintains the movable element in the inserted position. The release mechanism is coupled to the interlock mechanism, accessible from outside the receptacle housing, and operable to disengage the interlock mechanism from the movable element to permit the movable element to move to the extended position. The blocking element is located within the receptacle opening and is designed to move along the longitudinal axis with the movable element, to fixedly block a portion of the receptacle opening when the movable element is in the inserted position, and not to fixedly block the receptacle opening when the movable element is in the extended position.

Title: Apparatus for circular court ball game
Inventor: CRAIG GREGORY
IPC: A63B63/00
Filed: 1997-11-04
Abstract: This invention in an apparatus for use in a round ball rebounding game played on a circular court consisting of a spherical structure (8) supported by a single pole (14), and having a plurality of goals (22, 24, 26) placed at equidistant intervals about the maximum horizontal diameter of the sphere, and parallel to the playing surface (52). The apparatus further comprises a plurality of discharge tubes (36, 38, 40) inserted into the bottom of the sphere, said number of tubes corresponding to the number of goals. Openings are further cut into the sphere relative to the position of each goal such that a net (39, 32, 34) attached to the bottom of each goal can direct a round ball into the interior of the sphere, with the ball eventually departing the bottom of the sphere through one of the discharge tubes which then deposit the ball at the base of the structure along the playing surface.
Patent CA-2311102-A1 (CA)
Title: Exercise device and kit
Inventor: WINSTON EDITH
IPC: A63B21/06
Filed: 2000-06-02
Abstract: A handle for use with an elastomeric tube in a resistance exercise device is generally U-shaped with a grip removably secured between opposite ends of the handle. A frusto-conical throat is defined through the nadir of the U- shape and receives one end of the tube. A retainer ball of greater diameter than the tube is inserted into one diametrically stretched end of the tube. The diameter of the retainer ball is smaller than the large diameter proximal end of the throat but greater than the small diameter distal end of the throat. With the end of the tube stretched about the retainer ball, the ball compresses the tube wall against the frusto-conical throat wall with a force that increases as the tension in the tube increases (i.e., as the tube is pulled distally). As a result, the tube is prevented from becoming loose and becoming disengaged from the handle during use. Alternatively, a collar may be disposed about the tube distally of the retainer ball to prevent the retainer ball and surrounding tube portion from distally traversing the throat, thereby securing the tube to the handle. In yet another manner, the throat may include various configurations to provide a fitted engagement with the retainer ball and surrounding tube portions. The handle structure is preferably sold as part of a kit, and can be modified so that a second weighted bar, parallel to the weighted grip, can be removably connected between the arms of the U--shaped handle.
Patent CA-2313360-A1 (CA)
Title: Laser sighting beam modification for measuring or treatment instrument
Inventor: HOLLANDER MILTON BERNARD
IPC: G02B23/00
Filed: 2000-07-04
Abstract: The invention relates to modification of a laser beam produced,for purposes of aiming at a target, by instruments for measuring,controlling and treatment, such as pyrometers. It is known to provide such instruments with a single laser beam for aiming purposes. It is also known to provide such instruments with a plurality of divergent beams serving to define an area of a target. In a first embodiment the present invention provides a carrier having a beam splitter movable out of and into the path of the laser beam so as to provide respectively a single aiming beam and a plurality of fractional beams for defining an area of a target. In a preferred form, provision is made for periodical and repeated movement of the beam sputter into and out of the path of the aiming laser beam. In another embodiment, provision is made to increase the power of the single aiming beam at the time of splitting it into fractional beams; conversely where a relatively high power is applied to the laser beam whilst it is split to provide fractional beams, provision is made to reduce the power of the laser at such times as it has reverted to a single laser beam, or again to pass the single laser beam through an attenuator. A further feature is the provision of movement of the beam splitter into and out of the path of the aiming laser beam at a rate high enough to ensure persistence of vision, say at least twelve times per second. A further feature of the invention is the construction of the beam-splitter carrier and of the instrument so as to be readily engageable onto and disengageable from each other, as for example by screw-threading, push-fit, snap-action or other readily releasable mechanical structure. The invention further provides methods, for aiming of such an instrument at a target by use of a single beam, and splitting the aiming beam into fractional beams for defining a selected area of the target, and particularly as an automatically repeated action, the fractional beams being directed, for example, to indicate points on the target bounding a selected area thereof; or again being directed at successive shifted points bounding the selected area of the target, or yet again with the fractional beams being merged to define a closed loop area of the target.

Title: Epaississement de suspensions minerales aqueuses
Inventor: ALLEN ANTHONY PETER
IPC: C02F11/147
Filed: 1999-01-18
Abstract: L'invention porte sur un procédé d'épaississement par sédimentation de la teneur en solides d'une suspension minérale aqueuse, ce procédé consistant à ajouter à la suspension un floculant polymère de pontage, anionique, soluble dans l'eau, dont la viscosité intrinsèque est d'au moins 5 dl/g et un floculant polymère cationique soluble dans l'eau; permettre aux solides de se déposer par gravité de façon à former une fraction inférieure de sousverse contenant une concentration de solides supérieure à celle de la suspension, et une fraction supérieure de sousverse contenant une concentration de solides inférieure à celle de la suspension; puis. retirer la fraction de sousverse. Ce procédé se caractérise en ce que les floculants anioniques et cationiques sont ajoutés à la suspension sous forme d'une composition aqueuse qu'on obtient en mélangeant une partie en poids du floculant polymère cationique avec 2 à 99 parties en poids du floculant polymère anionique et une quantité d'eau suffisante pour obtenir une concentration polymère totale inférieure à 5 %, et dans des conditions favorisant la précipitation de contre-ions et ou la composition aqueuse de la quasi totalité du floculant polymère anionique qui n'est pas précipité par le floculant polymère cationique est dans la solution. L'avantage de cette invention est que les floculants ne sont pas limités par des considérations de compatibilité, et que, par conséquent, il n'est pas nécessaire (comme dans la technique antérieure) d'utiliser, par exemple, des floculants cationiques à base libre et des floculants anioniques à acide libre en essayant de minimiser les incompatibilités, ni d'ajouter un acide, un sel ou autres additifs.
