Patent CA-2174372-A1 (CA)
Title: Livestock waterer
Inventor: ROBINSON S ERIC
IPC: A01K7/06
Filed: 1996-04-17
Abstract: The livestock waterer is sufficiently insulated for cool or hot-weather applications, and avoids double-wall construction while still providing sufficient structural integrity and strength. The waterer uses a single-walled structure, with the shell having a solid high density plastic outer layer, and an integrally-bonded inner foamed plastic insulating layer of substantially lower density. The waterer has a generally-enclosed reservoir defined by a plastic shell, the shell having at least one bucket defined in an upper surface thereof extending below a nominal waterline. Each bucket has at least one opening communicating with the reservoir to receive water therefrom and at least one insulated access door across an upper portion thereof, depressable by an animal to gain access to water in the bucket. A float valve or the like maintains the water level. Preferably, the outer layer is high density polyethylene, and the inner layer is closed-cell foamed polyethylene having one-quarter or less of the density of the outer layer. Preferably, the shell is not more than one inch thick, and the inner layer accounts for most of the thickness. Preferably, each bucket is supported at a bottom edge thereof at least at several points around the bottom edge, by projections defined in the bottom of unit's shell. Preferably, these supports are inseparable from the buckets.

Title: Mop head retainer
Inventor: DI GIAMMARINO SILVIO
IPC: A47L13/24
Filed: 1996-11-28
Abstract: A mop head retainer for a mop head, having a shank for connection to a mop handle, an elongated body secured at its middle to the shank, and a jaw cooperable and pivotal with respect to the body to releasably grip and retain the mop head between the jaw and the body and release it therefrom, wherein the elongated body is provided with opposite, spaced first and second terminal extensions downwardly extending from the ends of the body, one end of the jaw being pivotably secured to the lower free end of the first extension, the other free end of the jaw and the inside surface of the lower end of the second extension being provided with co-operating engagement means releasable upon spacing apart of the lower end of the second extension and the free end of the jaw in a direction generally normal to the direction of rotation of the latter at its closed position, so that when in engaged position the jaw and the body are secured in spaced parallel orientation; the second terminal extension also extending upwardly from the corresponding end of the body and being pivotably associated between its ends with the body for outward movement of the lower free end of the second terminal extension away from the jaw; the retaining means being further provided with an elongated semi-rigid release member, one end of the member is attached to the shank at a point spaced from the body, the other end of the member is attached to the upper end of the second terminal extension, whereby downward pressure on a part of the release member between its ends causes deflection of the release member to pivot the second terminal extension and consequently move the lower end of the terminal extension away from the jaw to release the engagement means when in a closed position and permit the jaw to open, and removal of the downward pressure causes the release member and the second terminal extension to return to original positions to permit re-engagement of the engagement means when the jaw is to be closed; a protective member secured to the shank and extending towards the upper end of the second terminal extension, the release member being positioned between the protective member and the body, whereby the release member is shielded against unintentional disengagement of the engagement means by unintentional deflection of the unintentional deflection of the release member during use of the mop; the improvement comprising the protective member is provided with a pressure member having an abutable portion downwardly extending towards and adjacent the release member and operably abutable with the release member to effect the downward pressure on the part of the release member to effect the release of said engagement means. The pressure member allows for easier and cleaner manipulation of the retainer when replacement of the mop head is carried out.
Patent CA-2193298-A1 (CA)
Inventor: SORENSEN SOREN CHRISTIAN
IPC: B29C45/44
Filed: 1996-12-18
Abstract: In a method of injection molding a tie that includes an abutment wall surface having at least one tooth inside a locking head facing a pawl is formed in a mold that defines a tie in which the abutment wall includes at least one bulge adjacent each of opposite ends of the abutment wall for holding the abutment wall in the respective mold parts when the mold parts are first separated, with the at least one bulge adjacent one end of the abutment wall being defined by a first mold part and the at least one bulge adjacent the opposite end of the abutment wall being defined by a second mold part. As the first and second mold parts are being separated, the bulges initially hold the abutment wall in the respective first and second mold parts and thereby stretch and reduce the thickness of the abutment wall so that the tie can be removed from the mold without significantly damaging the at least one abutment surface tooth.
Patent CA-2194982-A1 (CA)
Inventor: TONKIN MARK
IPC: G01S13/931
Filed: 1995-07-14
Abstract: Le système de cette invention comprend un dispositif de commande intégré dans un premier véhicule (16) et un capteur (20) pouvant être mis en oeuvre pour mesurer la distance de séparation et la vitesse relative d'un deuxième véhicule (18) roulant derrière le premier véhicule (16). Le dispositif de commande reçoit également un signal de vitesse provenant d'un capteur (97) de vitesse qui détermine la vitesse au sol du premier véhicule à l'aide d'un radar Doppler. Le dispositif de commande calcule un périmètre de sécurité et active un avertisseur visuel attaché à l'arrière du premier véhicule si le deuxième véhicule pénètre dans le périmètre de sécurité. Un périmètre de sécurité renforcée déterminé par de mauvaises conditions de circulation est également établi, toute incursion dans le périmètre renforcé ayant généralement pour effet d'activer l'avertisseur visuel à un niveau faible. Cependant, si la vitesse de rapprochement du deuxième véhicule dépasse un seuil prédéterminé, toute pénétration dans le périmètre renforcé produit l'activation immédiate de l'avertisseur à son niveau le plus complet avec signalisation maximum pour le conducteur du deuxième véhicule. Ce système s'applique pour améliorer la sécurité des véhicules sur la route.

Title: Clippits
Inventor: ACLAND LOU
IPC: A44C7/00
Filed: 1997-02-04
Abstract: Pierced earring manufactured of fourteen (14) to twenty-four (24) carat, .06mm to .09mm gold wire. Wire is configured along the lines of a conventional shepherd hook design with the end of the wire forming a small loop at the bottom and partially returning perpendicular along the main body of the wire. This end portion of the wire is left open and unsecured to the main wire. A cylinder or oval shaped tube of the same carat gold and slightly larger in diameter opening is placed over the main body of the wire.  This tube is designed to slide down the main wire and over the portion of the wire returning perpendicular to the main body of the earring. A 1mm gold bead is then soldered above the tube, when it is in a full up position, to the main wire.  This bead prevents the sleeve from sliding off the wire.  In this full open position a wide variety of commercially available costume drops of various composite materials may be added to the gold earring by placing the drop fastening mechanism (ususally a jump ring) over the perpendicular wire and between the maim wire down into the looped space. The sleeve is then slid down enclosing both wires and securing the drop in place.
