Patent CA-2225280-A1 (CA)
Inventor: BAYNES IAN DAVID
IPC: F16B7/04
Filed: 1996-09-04
Abstract: In a snap connection system in which a shaft (16) is inserted into a tube (10) to a predetermined position, whereat co-operating surfaces on tube and shaft engage as in a laterally acting wedge, two axially spaced spring loaded balls (12) on one side of the tube urge the shaft into wedging engagement with the tube when in position. During insertion, a further spring loaded ball (13) on the opposite side of the tube adjacent the wedge apex urges the shaft out of wedging engagement with the tube. A detent (17) in shaft (16) accommodates the further ball (13) at the predetermined position, locating the shaft axially and permitting wedging. The balls are biassed by a spring sleeve (11), and a tang (14) thereof locates the sleeve on the tube. The tang may extend to the tube interior to coact with a detent in the shaft so that unclipping is necessary for disassembly. Alternatively, a spring loaded pin extending through sleeve and tube wall may accomplish the same end.

Title: Universal mould carrier with improved air flow compensation
Inventor: NITSCHE REINHOLD ERNST
IPC: B29C49/06
Filed: 1998-05-29
Abstract: A universal mold carrier for use in a mold assembly compensates for parting forces associated with container formation by directing a compensating air flow pressure to the rear surface of the mold carrier. The mold carrier comprises two mold halves adapted to matingly engage each other and hold within the mold carriers interchangeable mold shells. One of the mold carriers has an outside wall that has a plurality of independent air flow compensating surface areas located thereon. This mold carrier further has an air flow communication line interconnecting the independent air flow compensating surface areas. Shut off valves are located in the one carrier to close and to open the air flow communication line between adjacent independent air flow compensating surface areas to allow for adjustment of the compensating pressure. The shut off valves each include a valve stem adapted to open and close the valve thereby connecting or disconnecting the independent air flow compensating surface areas located on opposite sides of the valve. The valve stem is positioned in the carrier along its parting wall which is accessible to an operator when the mold halves are open. The mold half carrier permits an operator to open or close off supply of compensating pressure applied to different compensating systems during a quick change over of the mold shells carried by the mold half carriers.

Title: A scheme to perform event rollup
Inventor: MANCISIDOR RODOLFO AUGUSTO
IPC: G06F9/46
Filed: 1998-06-29
Abstract: A user definable set of event rollup relationships are maintained as a configuration element. Transitive closure of event rollup relationships is checked at the time of specification to detect cycles and prevent runtime errors. When an event to be processed is detected, the event is compared to defined rollup relationships and queued events to determined if the detected event may be rolled up into at least one queued event or vice versa. If the detected event may be rolled up into a queued event, the detected event is not queued. When any of the queued event may be rolled up into the detected event, the queued events are deleted if processing has not already begun.

Title: Removal of heavy metals from aqueous solutions using sodium di-(n-octyl) phosphinate
Inventor: ESALAH JAMALEDDIN
IPC: C02F1/54
Filed: 1998-08-20
Abstract: Two organophosphorus compounds: sodium di-(n-octyl) phosphinate and sodium di-(n-dodecyl) phosphinate, were synthesized and purified. Sodium di-(n-octyl) phosphinate was used both as a surfactant to form reverse micelles and as a precipitating agent to remove heavy metals from aqueous nitrate and chloride solutions.      The heavy metals lead, cadmium, and zinc were precipitated from aqueous solutions with sodium di-(n-octyl) phosphinate (NaL) in the form of PbL2(s), CdL2(s), and ZnL,2(s). The mole ratio of NaL to lead in the feed was varied from 0.1 to 6.5, depending on the acidity of the feed. The effects of the feed pH, concentration of chloride, concentration of calcium, and of the chain length of the precipitating agent on the removal of lead, were investigated. Adding acid to the feed solution reduced the removal of lead as some of the phosphinate precipitated in the acid form as HL(s). The presence of chloride or calcium in the feed solution, up to mole ratios to lead of 250 and 2.75, respectively, had no effect on the removal of lead. The solubility of the precipitate PbL2(s) was reduced by increasing the length of the alkyl group of the phosphinate. The removal of cadmium, zinc, and a mixture of lead, cadmium and zinc was investigated. Behavior similar to that of lead was observed. The selectivity of the precipitating agent for the three metals was in the order Zn > Pb > Cd.      The precipitating agent was completely regenerated by adding NaOH to the precipitate, and then contacted with diethyl ether to extract the reagent. The lead was completely recovered from the PbL2(s). Pure lead-free precipitating agent, and an aqueous solution of lead at a concentration 100 times its concentration in the feed, were obtained. Using measured solubility products of the precipitates and literature values of the stability constants for the other expected reactions, the removal of metal, the loss of precipitating agent, and the equilibrium pH were predicted.

IPC: H01R4/36
Filed: 1993-04-29
Abstract: The present invention relates to a protective sheath for protection and separating a plurality of insulated cable conductors from a single cable that includes a layer of protective armor surrounding all the conductors extending from down hole along production tubing in an underground well.  The protective armor terminates at a separating point of the cable conductors so that the plurality of cable conductors are separated into individual cable conductors. The sheath is comprised a hollow rigid tube for enclosing the plurality of insulated cable conductors and protective armor. A plurality of individual rigid tubes are integrally formed to and enclose one end of the rigid tube so that each one of the plurality of cable conductors is routed into a separate rigid tube.  Each one of the plurality of rigid tubes encloses a corresponding one of the individual cable conductors.  The rigid tube and individual rigid tubes are sized to confine but not sealingly engage the conductors when the well is pressurized for preventing excessive expansion of the insulation on the conductors during well depressurization.

Title: Network directory access mechanism
Inventor: DULOUTRE SYLVAIN
IPC: G06F12/00
Filed: 1999-02-23
Abstract: A computer-implemented directory access mechanism provides a directory service operable to access a network directory under a predetermined protocol by responding to an access request under the protocol for information available in a predetermined environment external to the directory. The directory service then uses the access method for the environment to access the information available in the environment. In this manner, data in the given environment can be accessed by a directory service operable under the given protocol by configuring an attribute access method and using this method to retrieve the information. The protocol can be the Lightweight Directory Access Protocol. The information to be accessed could typically be an attribute of an entry in the directory. An access control list (for example the Directory Access Control Domain) can contain not only control access rights for directory objects, but also the access methods for attributes of the directory objects.
