Title: Induction heating coil assembly for prevention of circulating currents in induction heating lines for continuous-cast products
Inventor: PEYSAKHOVICH VITALY
IPC: H05B6/36
Filed: 1996-05-13
Abstract: An induction heating coil assembly for use in a roller induction heating line has a magnetic shunt for receiving a portion of an electromagnetic field generated along the axis of the induction coil and directing that portion along a path parallel to a workpiece passing along the heating line. This flux path ensures that eddy currents induced in the workpiece flow primarily perpendicular to the axis of the workpiece, and not along the axis of the workpiece where they could cause arcing between the moving workpiece and the conveyor rolls.

Patent CA-2187810-A1 (CA)
Inventor: MARSCHKE CARL R
IPC: B05C11/04
Filed: 1996-10-11
Abstract: APPARATUS AND METHOD FOR APPLYING A VISCOUS LIQUID TO A MATERIAL SURFACE             An adhesive or other viscous liquid applicator apparatus utilizes a cylindrical glue roll and a reverse acting notched metering or doctor blade which forms, from an initial liquid layer on the roll, a series of laterally spaced liquid beads of metered size.  The beads are subsequently spread to form a liquid layer for transfer to a web or other surface moved into generally tangential contact with the roll.  The beads are preferably spread by a flexible spreader blade, but may also be spread by operating the peripheral surface of the roll and the web or surface in contact therewith at different speeds. The notched doctor blade provides accurate metering with a mechanically simple apparatus and the formation of beads helps prevent premature drying of the liquid.

Inventor: KOLTZ MORTON I
IPC: B65D5/36
Filed: 1997-03-13
Abstract: This invention relates to pop-open bowls or trays,  and in particular to planar devices that can be folded from a single sheet of material into free standing three dimensional bowls or trays for holding or containing various items or substances.  Bowls, trays or boxes foldable from a single sheet of material are often complex devices with numerous tabs and slots and are therefore expensive to manufacture and difficult and time consuming to assemble into a functional form.  What is provided by the present invention is a bowl,  foldable from a single sheet of material,  which can be erected to a usable form in one single rapid motion and consists of no interlocking tabs or notches to complicate that operation.

Abstract: This invention is in the field of devices used to trim and lower hedges and trees. The device consists of a guide bar with a drive means and a saw chain travelling around the circumference thereof, along with a set number of dividers extending forward from and above and below the guide bar. The design of the dividers, along with the spacing there between, allows the device to trim branches of larger diameter than analogous devices found in the prior art, and a clean level surface is left on the lowered hedge. The size of the device itself allows for the even trimming of large hedges.
Patent CA-2202044-A1 (CA)
Title: Transmitting digital data using multiple subcarriers
Inventor: PARK DANIEL J
IPC: H04J1/00
Filed: 1995-09-21
Abstract: Two separate subcarriers (16, 22) are used to transmit portions of a single message to one or more receivers on an FM radio signal. The synchronization and addressing data necessary to identify the message to a target receiver is located in the first subcarrier. The second subcarrier, in turn, consists almost entirely of raw message data. Thus, transmitting multiple subcarriers substantially increases the overall data transmission payload when transmitting digital messages. Because each subcarrier is located within a different frequency band, the communication system is also adaptable to different subcarrier allotments in the FM baseband.

Title: Free-roaming remote hand-held point-of-sale terminal
Inventor: COVELEY MICHAEL
IPC: G06Q20/04
Filed: 1996-02-22
Abstract: A financial transaction system (10) is provided in which a user is given a portable RF financial transaction terminal (20) with which to enter transaction data via a keypad (52) or read a UPC bar code on merchandise via a CCD scanner (42) and read their credit, debit or smart card. The RF financial transaction terminal (20) transmits the transaction and card data to a central network controller (12) via a RF communications link. The central network controller (12) in turn conveys the transaction and card data to the host computers at a financial institution where the transaction is processed in real-time. The financial institutions return verification data to the central network controller which is passed back to the RF financial transaction terminal via the RF communications link. The RF financial transaction terminal then generates a printed receipt of the transaction for the user. All of this may be done while the RF financial transaction terminal and the user's credit, debit or smart card remains in the total custody of the user. The user is therefore relieved from having to proceed to an ABM, retail platform, cashier's desk, etc.
Patent CA-2214121-A1 (CA)
Title: Retroreflective applique
Inventor: BILLINGSLEY BRITTON G
IPC: B44C5/08
Filed: 1996-02-13
Abstract: A retroreflective applique (10) includes a supporting structure (12), a layer of optical lens elements (14), and a reflective material (16). The layer of optical lens elements (14) is partially embedded in the supporting structure (12), and the reflective material (16) is disposed on the embedded portion of the layer of optical lens elements (14). The supporting structure (12) may contain a binder layer (24) and a heat-activatable adhesive layer (26). The binder layer (24) includes a non-filamentary acrylic polymer layer. The use of such a supporting structure (12) eliminates the need for a release liner on the rear surface (20) of the heat-activatable adhesive layer (26), and it also enables a carrier web (28) to be separated from the polymeric supporting structure (12) before the applique (16) is permanently secured to a substrate. The separation step can be accomplished without causing substantial harm to the retroreflective performance of the applique (10).

Title: Old or waste plastics treatment process
Inventor: STRECKER CLAUS
IPC: C10G1/00
Filed: 1996-05-02
Abstract: According to the process described, old or waste plastics are depolymerized into a pumpable phase and a volatile phase to allow recovery of chemical raw materials and liquid fuel components. The volatile phase is separated into a gaseous phase and a condensate. In order to simplify the process in comparison with the state of the art, the depolymerised product remaining after the volatile phase is separated is also heated together with the condensate or condensate fractions in the presence of hydrogen under pressure and is subjected to hydrotreating, after non-boiling components are removed, to produce syncrude.

Patent CA-2222445-A1 (CA)
Title: Improved damper
Inventor: JEFFRIES MARK S
IPC: F16F9/34
Filed: 1997-11-26
Abstract: The orientation insensitive, non-cavitating differential, bi-directional damper has a tubular body defining a closed, elongated chamber that has a first end and a second end. A piston assembly is disposed in and is movable within a portion of the chamber. One end of a piston shaft is connected with the piston assembly and the other end of the shaft extends out of one end of the chamber. Another assembly is disposed in the chamber between the piston assembly and the other end of the chamber. A floating piston is disposed in the chamber and is movable in the chamber between the other assembly and the other end of the chamber. The portion of the chamber between the other end of the chamber and the floating piston is filled with gas while the remainder of the chamber is filled with fluid. The floating piston is spring biased toward the other assembly. Orifices in the piston assembly control the rate of fluid flow across the piston assembly when the piston assembly moves relatively to the tubular body. The orifices in the other assembly control the rate of fluid flow across the other assembly when the piston assembly moves relatively to the tubular body.
