IPC: A23G1/30
Filed: 1994-07-13
Abstract: ABSTRACT            Chocolate Shape Retention A process for improving the shape retention of chocolate or chocolate type products so that they have a reduced tendency to deform at elevated temperatures which comprises mixing an encapsulated product in particulate form comprising capsules of a polyol enclosed within an edible lipid with a flowable mixture of chocolate type ingredients, the encapsulated product being added in an amount to achieve a polyol content of from 0.2 to 5% by weight based on the total amount of the resultant chocolate.

Abstract: FEMALE CLINCH FASTENER WITH COLD-FORMED.      LOCKING FLANGE AND ASSOCIATED      INSTALLATION METHOD                Field of the Invention The invention relates to the field of fasteners, and, more particularly, to a female clinch fastener, or clinch nut, mounted to a sheet and an associated method for installing the clinch fastener.               Background of the Invention A conventional female clinch fastener, or clinch nut, is permanently installed into a portion of a metal sheet so that the nut becomes an integral part of the metal sheet.  The clinch nut is installed by cold-forming the metal of the sheet or the nut, rather than welding.  The clinch nut thus provides a threaded bore with greater holding capacity than could be obtained by simply threading an opening in-the sheet metal alone.  Such a clinch nut is commonly used in automobiles to provide a means for fastening bolts to a metal sheet, for example.          One conventional clinch nut is available from RB&W Corporation of Mentor, Ohio, under the designation SPAC?nut.  The SPAC?nut includes a back-tapered polygonal portion that is press fit into a slightly undersized opening in-a sheet.  The nut is locked into the sheet by a coining action as the sheet material

Patent CA-2137959-A1 (CA)
Title: Coupling device between a glass fibre and a dielectric waveguide
Inventor: KERNDLMAIER WALTER
IPC: G02B6/30
Filed: 1994-12-13
Abstract: A coupling device allows glass fibre to be coupled to a dielectric waveguide integrated on a substrate.  The object of the invention is to produce a cost-effective coupling device with low-loss and low-back-scatter.  This object is achieved by reducing the end of the glass fibre -- principally, by drawing the fibre under heat exposure until breakage -- to a diameter in the order of typical core dimensions of dielectric waveguides, and by providing on the substrate a fibre receiving portion that reduces in its dimensions in a similar way and changes at its tip into the waveguide to be coupled.  Assembly only involves inserting the glass fibre into the fibre receiving portion as far as possible.  The fibre centres itself in the waveguide as it is inserted.  The tolerances in the fibre geometry do not lead to the level of loss encountered with the prior art front face coupling method.

Patent CA-2170832-A1 (CA)
Title: Submersible canned motor transfer pump
Inventor: GUARDIANI RICHARD F
IPC: F04D7/04
Filed: 1996-03-01
Abstract: A transfer pump used in a waste tank for transferring high-level radioactive liquid waste from a waste tank and having a column assembly, a canned electric motor means, and an impeller assembly with an upper impeller and a lower impeller connected to a shaft of a rotor assembly. The column assembly locates amotor housing with the electric motor means adjacent to the impeller assembly which creates an hydraulic head, and which forces the liquid waste into the motor housing to cool the electric motor means and to cool and/or lubricate the radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the upper impeller and electric motor means grind large particles in the liquid waste flow. Slots in the static bearing member of the radial bearing assemblies further grind down the solid waste particles so that only particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the transfer pump. The column assembly is modular so that sections can be easily assembled, disassembled and/or removed. Asecond embodiment employs a stator jacket which provides an alternate means for cooling the electric motor means and lubricating and/or cooling the bearing assemblies, and a third embodiment employs a variable level suction device which allows liquid waste to be drawn into the transfer pump from varying and discrete levels in the waste tank.

Title: Intelligent Call Forwarding
Inventor: RAO USHA
IPC: H04Q3/00
Filed: 1996-04-01
Abstract: Intelligent call forwarding is implemented through an intelligent network. The intelligent network includes a Service Switching Point (SSP), a Service Control Point (SCP), and a Service Management System (SMS). A call to a network subscriber is routed to the SSP which is used to detect Call Forwarding "triggers" -  conditions which require the SSP to initiate selective Call Forwarding service. When a Call Forwarding trigger is detected the SSP passes the calling party's number to the SCP and requests call handling instructions from the SCP. The SCP provides the call handling instructions, as provisioned by the subscriber, to the SSP, and the SSP then forwards the call in accordance with the instructions. The SMS formulates and sends commands to the SCP for such purposes as changing the stored subscriber instructions or updating service features. By provisioning the SCP with appropriate instructions the forwarding destination for a call may be made to depend upon the time of day, day of the week, caller's identity, and/or status of the called telephone.
