Patent CA-2194615-A1 (CA)
Title: Preform injection mould with slide taper locks
Inventor: WRIGHT JOHN B
IPC: B29C45/33
Filed: 1997-01-08
Abstract: A preform injection mould includes an elongate mould core co-operating with a female mould and a neck ring in a manner to define a mould cavity therebetween. An injection nozzle in the female mould allows molten plastic to be injected into the mould cavity so that a preform moulded article may be formed. The neck ring is constituted by a pair of mating halves which can be separated laterally with respect to the longitudinal axis of the mould core. A taper sleeve surrounds the mould core beneath the neck ring. The neck ring halves are secured to diametrically opposed slides to facilitate lateral separation of the neck ring. A pair of slide taper locks contact a respective one of the slides to inhibit lateral movement of the slides and to back up the neck ring when injection mould is in a mould closed position. An annular formation is formed on the upper surface of the neck ring and is accommodated by a complementary recess formed in the bottom of the female mould. The mating inclined surfaces of the female mould and the annular formation constitute an upper taper lock which is backed up by a cavity plate. An annular formation is provided on the upper surface of the taper sleeve and is accommodated by a complimentary recess formed in the bottom of the neck ring. The mating inclined surfaces of the taper sleeve and neck ring constitute a lower taper lock. Since a portion of the neck ring constitutes the female taper of the lower taper lock, the lower taper lock is backed up by the slide taper locks through the slides allowing the cross-sectional area of the neck ring to be reduced.

Patent CA-2207340-A1 (CA)
Inventor: LAFORGE MARTIN
IPC: G06F9/44
Filed: 1997-06-23
Abstract: La plupart des systèmes informatiques développés au cours des dernières décennie s emmagasinent et traitent les dates. Cependant, en raison du coût de l'espace mémoire et de l'esp ace magnétique nécessaire à mémoriser ces données, la représentation informatique numérique des dates est souvent limitée à 6 chiffres soit: la décennie (1), l'année (1), le mois (2) et le jour (2). Le millénaire et le siècle étant toujours constants, ils ont été tronqués sans nuire à la bonne marche des systèmes. Par contre, depuis quelques années déjà, la communauté informatique mondiale est consciente que le passage à l'an 2000 rendra inopérant plusieurs systèmes informatiques qui utilis ent des dates numériques tronquées. En effet, puisque les dates tronquées des années 2000 devi endront identiques aux dates tronquées des années 1900, plusieurs systèmes informatiques produiront des résultats invalides car les opérations mathématiques et les comparaisons arithmétiques eff ectuées sur les dates retourneront des résultats erronés. En conséquence d'importantes modifications a ux systèmes informatiques s'avèrent nécessaires. Plusieurs systèmes informatiques doivent êt re adaptés afin de gérer simultanément les dates de deux siècles différents. Dans la présente invention, une nouvelle méthode de représentation interne des d ates tronquées permettra d'adapter à moindre coût les systèmes informatiques qui sont affectés par l'arrivée de dates supérieures à l'an 1999. Cette nouvelle représentation interne est basée sur des concepts informatiques connus mais permet d'emmagasiner dans un même espace mémoire ou ma gnétique les dates de six décennies supplémentaires (jusqu'à l'an 2059) tout en conservant de façon intégrale toute les dates déjà enregistrées et présentes dans les systèmes informatiques.

Title: Method and apparatus for flow control of nh3
Inventor: CESSAC KEVIN J
IPC: A01C23/00
Filed: 1998-05-29
Abstract: The present invention provides an apparatus and method for accurately controlling the amount of NH3 to be applied to a field by measuring the NH3 flow rate without condensing or cooling the NH3. The system includes a control station 12 on the vehicle with a tachometer 12A or a GPS system for providing a vehicle speed signal to a control panel 13. The control panel includes a toggle switch 17 for adjusting the opening or closing of a valve 52 in the flow line to regulate the flow through the system, although the control panel alternatively may automatically control the valve 52. The vehicle transports a tank 20 containing liquid NH3 and a tool bar 30 for distributing the NH3 to the soil. After flowing through the flow meter 40, 60, 130, the NH3 is conducted to the soil through a series of hoses, fittings, a distributor, and tubing. The flow meter transmits a signal to the control panel, which is converted to a corrected flow rate signal in response to a fixed value vaporization correction factor. The temperature of the NH3 is also measured to correct for density variations. An improved variable area meter 60, 130 uses a hall effect sensor 72 and a magnet 68 mounted on a rotatable vane shaft 70 to overcome problems with prior flow meters. The improved meter 60, 130 is ideally suited for measuring the fluid flow of a low temperature vaporization liquid, such as anhydrous ammonia, propane and butane.
