Patent CA-2002523-C (CA)
Inventor: CHAMBERS TIMOTHY D
IPC: A63B67/08
Filed: 1989-11-08
Granted: 2000-05-16
Abstract: A toy for throwing, bouncing, and catching has a cylindrical padded hand gripped rod, which extends at each end to and partially into respective high bounce balls. The balls each have a cylindrical recess with a respective clearance tapered entry, formed from a previous spherical portion of a high bounce ball, or so directly formed upon molding the initial form of the respective high bounce ball. Such clearance tapered entry of each high bounce ball improves the recovery of each ball during and after being impacted under striking load conditions, and thereby improves the longevity of the high bounce balls and the overall toy. A padded sleeve conforming to the hand gripped cylindrical rod has tapered ends to also provide clearances, where the padded hand gripped rod meets the high bounce balls, to likewise improve the longevity of the overall toy.

Title: Screen assembly for screening elastomeric material
Inventor: GREENSTREET ARTHUR W
IPC: B07B1/46
Filed: 1990-02-02
Granted: 1999-11-02
Abstract: A screen assembly for mounting on the outlet end of an extruder for removing foreign particles from an elastomeric material being discharged from the extruder.      The assembly includes a screen support member having a plurality of spaced elongated ribs formed integrally with or removably mounted on a surrounding member. The spaced ribs form a plurality of elongated slots therebetween which provide flow paths fox the elastomeric material, and preferably are concavely-shaped in the direction of travel of the extruded material. A mesh screen formed of a high tensile strength, work hardened stainless steel wire cloth is formed complementary to the concavity of the ribs and is mounted in juxtaposition, to the ribs for removing the foreign particles as the elastomeric material passes through the screen. The concavity of the ribs and formation of the elongated material flow paths, reduce the amount of back pressure created in the elastomeric material and reduces the bending and shear forces created on the ribs and surrounding support member.

Inventor: FRANZ LENNART
IPC: B65D47/02
Filed: 1990-05-25
Granted: 2000-05-23
Abstract: L'ensemble de valve pour emballage perdu comporte un boîtier de valve renfermant un clapet principal et un clapet auxiliaire initialement maintenu en position d'ouverture par un verrouillage élastique qui est déverrouillé, en fin d'un premier remplissage, par un déplacement du clapet principal au-delà de sa position d'ouverture normale sous l'action d'un robinet de remplissage à course longue. Le clapet auxiliaire est alors plaqué en appui sur son siège par un ressort à faible tarage. Toute dépression de soutirage provoque l'ouverture du clapet auxiliaire, alors que toute surpression de remplissage se heurte au clapet auxiliaire en position de fermeture. Ce système élimine la possibilité d'un quelconque remplissage ultérieur par un utilisateur.

Patent CA-2019582-C (CA)
Title: Nestable and stackable tray for cans or the like
Inventor: APPS WILLIAM P
IPC: B65D1/36
Filed: 1990-06-21
Granted: 1997-11-11
Abstract: Reusable plastic trays for storing and transporting beverage containers, such as twelve-ounce metal cans and two-liter PET bottles. The tray floor has thereon an array of support areas for the containers. The tray rail band thereof is spaced high enough above the floor to prevent container tipping and in a "low-depth" configuration. The outside rail band faces are vertical on both sides and are against the containers, and thereby add little to the outside tray dimensions. The inside face contacts and supports the peripheral containers. Columns between adjacent support areas interconnect the rail and the floor, angle downwardly and inwardly therebetween, open outwardly and form vertical nesting slots. The trays when empty can thereby be stacked in a deeply nesting position whereby each additional tray adds only the height of its narrow rail to the nested tray stack height. When the tray is a can tray, the bottom surface of the floor has a pattern of protuberances and recessed areas therebetween. When a loaded can tray is supported and located on a similar tray therebeneath, the lower can rims fit into the recessed areas and the protuberances are positioned both inside of and outside of the rims thereby locating and locking the upper tray in place. To unlock the upper tray it is simply twisted so that the protuberances ride up their bevelled edges onto the rims and into a sliding position.

Granted: 2002-11-12
Abstract: A pattern is impressed on flocked fabric by applying a patterned cylinder to the flocked surface before the adhesive that retains the flocking has cured. The projections on the cylinder surface tilt the flock fibers contacted by them to a new orientation, thereby forming the pattern in the flocked surface. Subsequent curing of the adhesive preserves the pattern.
Patent CA-2025657-C (CA)
Title: Method and apparatus for preventing bus contention problems between two processors
Inventor: SWANSON SCOTT C
IPC: A61F13/15
Filed: 1990-09-18
Granted: 2000-01-25
Abstract: A bus access controller. An interface circuit (22) controls the access of a host computer (10) and a microprocessor (23) to one or more UARTs (14, 15). The microprocessor (23), which has no provision for waiting for a data transfer, is required to provide a signal of its intent to perform a data transfer prior to beginning the actual data transfer. The signal is identical to the actual data transfer operation. If the host (10) attempts a data transfer operation while the microprocessor (23) is conducting a data transfer operation, or if the host data transfer cannot be completed prior to the time that the microprocessor data transfer will commence, then the interface circuit (22) signals the host (10) that the data transfer will take additional time by deasserting the I/O  READY line (12a). Once the microprocessor data transfer is completed then the I/O READY signal is reasserted and the host data transfer is completed, Bus contention problems and data loss are therefore prevented and the host (10) waiting time is minimized.

Abstract: There is disclosed a process for the preparation of isothiocyanates of formula   wherein R 1 and R 2 are each independently of the other C 1-C 6alkyl and R 3, R 4 and R 5 are each independently of the other hydrogen, halogen, C 1-C 4alkyl, C 1-C  4alkoxy, trifluoro-methyl or nitro, which process comprises reacting an amine of formula   with ammonium thiocyanate or an alkali metal thiocyanate, in the presence of acid and an inert solvent, to the thiourea of formula   and cleaving said thiourea by heating. The essential feature of this process consists in carrying out the reaction of the amine of the above formula with ammonium thiocyanate or an alkali metal thiocyanate in the presence of 0.5-5% by weight of water, based on the total weight of the reaction mixture. The isothiocyanates of the above formula are intermediates for the synthesis of pesticidal compounds.

Title: Expandable garment hanger
Inventor: HUNT WILLIAM JOSEPH
IPC: A47G25/62
Filed: 1990-03-08
Granted: 2000-05-16
Abstract: An expandable garment hanger with which the invention is concerned has a body (1), a hook (2) on the body to suspend the hanger and a pair of movable arms (3, 4) slidably mounted on the body. The arms are arranged to move in opposite directions. A locking device (8, 9) is located on the body (1) of the hanger so as to lock the movable arms relative to the body. The locking device is movable along a path parallel to the path along which the arms are movable. A biasing device, preferably a spring (27), is provided for biasing the locking device (8, 9) against movement in one direction so that when the arm of the hanger is set and locked in position the arms of the hanger are movable against the biasing force of the spring (27). The hanger conveniently supports garments of varying waist widths and maintains the hanger at the desired widths once the garment is mounted on the hanger but also allows the garment to be removed from the hanger by a small inward force applied to the end of the arm.
