Abstract: A fitment (24) for use on a container for dispensing liquids. The fitment (24) provides a pouring spout (26) and a drain back function (32, 44) and is secured within the container finish. The container finish has a neck (18) with a rim (22) and a shoulder (20). The fitment (24) has an outer wall (30) with upper and lower ends (36, 40) and with a frustoconical shape to ensure that a portion of the outer wall (30) frictionally engages the container finish when the fitment (24) is inserted into the container finish to prevent the fitment (24) from being inserted completely through the neck (18) of the container. An annular bead (34) extends outwardly from the outer wall (30) a spaced distance from the upper end (36) of the outer wall (30) so that when the fitment (24) is engaged in the neck (18) of the container, the bead (34) is positioned directly under the shoulder (20) of the neck (18). Multiple bands of sealing engagement are created between the fitment (24) and the container fitment to ensure a leak-free connection.

Patent CA-2270601-C (CA)
Inventor: GILBERT GORDON J
IPC: H04M3/51
Filed: 1999-05-03
Granted: 2002-05-28
Abstract: A method and system for using TCAP signaling for improved call setup from a virtual switching point are disclosed. In accordance with the method, TCAP signaling is used to enhance call setup from virtual switching points which receive call request messages from calling parties using a facility on a data network such as the Internet. TCAP signaling is used when necessary to determine the availability of the called party telephone. The system includes a Virtual Switching Point (VSP) in a switched telephone network having a connection to a data network such as the Internet. Call requests are received by the VSP from the data network and processed by the VSP to establish a voice connection between the calling party which initiates the call request and a called party number indicated in the call request message. The use of TCAP signaling from the VSP to Switching Points (SPs) which serve the calling party and/or the called party improves efficiency and minimizes common channel signaling. The VSP enabled with TCAP signaling can also be used as an efficient out-dialer for a call center. The advantage is the ability to offer more calling options while improving network use efficiency.

Abstract: A carbohydrate is added to sand, which has been used to make foundry moulds or cores, and which has been bonded using an alkaline resol phenol-formaldehyde resin, prior to reclamation of the sand by a thermal reclamation. The thermal reclamation may be done in other equipment, for example a rotary thermal reclamation unit, but is preferably done in a fluidised bed reclamation unit. The carbohydrate is preferably water soluble and is added to the used sand as an aqueous solution.  The carbohydrate may be for example a monosaccharide, such as glucose, mannose, galactose or fructose, or a disaccharide such as sucrose, maltose or lactose. The carbohydrate may also be a carbohydrate derivative such as a polyhydric alcohol (e.g. ethylene glycol, glycerol, pentaerythritol, xylitol, mannitol or sorbitol), a sugar acid (e.g. gluconic acid), or a polysaccharide derivative (e.g. a starch hydrolysate, i.e. a glucose syrup or a dextrin). The amount of carbohydrate used in the reclamation process is usually of the order of 0.25 %  to 5.0 % by weight based on the weight of used sand.
