Title: Framing system for signs
Inventor: VERRET NORMAND
IPC: G09F13/04
Filed: 1991-12-12
Granted: 1995-11-21
Abstract: The new  framing  system for signs provides a method of stretching the flexible sign material across the opening of a frame.   The  tensional devices are installed manually from the outside of the sign at regular spacings on the edges of the flexible sign material.  The tensional devices are installed by closing the device on, and by the same movement, puncturing retaining holes on the edges of the flexible sign material.  The adjustment of the tension of the flexible sign material is done by pushing inwardly on each tensional device to engage it onto a series of serrations inside a slot facing outwardly along the edges of the frame.  The outside edges of the frame are held rigid with frame members extending from the bottom of the sign, and thus eliminating  the  need for support members, between the flexible sign material and the lamps, which normally transmit shadows to the face of the sign.  The new framing system can be re-opened for maintenance purposes using a slot type blade screw-driver to pry the tensional  devices out of the serrations.  The tensional devices and the slot on the periphery of the sign are covered by a cap which locks in place on mating lips, and which can be removed manually by twisting it inwardly along its length.
Patent CA-2066560-C (CA)
Inventor: DUCKWORTH KENNETH
IPC: G01V3/11
Filed: 1992-04-21
Granted: 1998-05-19
Abstract: The present invention is a device for exploration of the subsurface conductivity of the earth by means of electromagnetic induction.  The device employs closely spaced transmitter and receiver coils mounted rigidly in a single unit in a configuration which permits the primary electromagnetic coupling between the coils to be eliminated so that only secondary fields from subsurface conductive structures are detected.  This elimination of the primary coupling is achieved by the use of solenoidal coils which are configured such that their axes are parallel but with the coil axes separated by a distance less than 50 cm. An offset of the coils centres in the axial direction to the point at which the curvature of the transmitted primary signal induces signals at the two ends of the receiver coil which are equal in magnitude but of opposite phase so that these two signals achieve mutual cancellation. The achievement and maintenance of this balance requires that the device be extremely rigid and stable and this requires that the coils be of solenoidal (elongated) form to achieve this rigidity. The transmitted signal is harmonic and in the frequency range 10 Hz to 20,000 Hz. The close proximity of the two coils allows them to achieve maximum coupling with subsurface conductors simultaneously so that the response of the device to such conductors is maximized. The strength of response that this provides is only matched by devices in prior art in very limited circumstances. The benefits of this device are its ability to resolve the separate responses of closely spaced conductive structures and to provide estimates of the geometry of a detected structure (depth and dip) at the time the structure is detected in the field. The device also offers an ability to discriminate between highly conductive structures that is not available in devices described in prior art. Operation of the device in the field can be achieved without the need for cut lines.

This information generally consists of the called number, but may also include an extension or other code. The called party identification is delivered to the called telephone station set during the silent period after ringing, or, advantageously before ringing starts. A signal (e.g.,FSK) is sent to the called telephone station set shortly before the ringing signal is sent to the called station. A converted at the customer premise receives the FSK signal and demodulates it. A control unit connected to the converter then causes the called DN to be displayed, may cause a distinctive ring to be made, or take other action depending upon its program.

Title: Explosion proof microwave heated solvent extraction apparatus
Inventor: REVESZ ROBERT N
IPC: B01D11/04
Filed: 1994-05-27
Granted: 2005-01-04
Abstract: An explosion proof microwave heated solvent extraction apparatus or system for extracting organic materials includes a pressure resistant microwave transmissive extraction container, which is preferably of reinforced polyetherimide lined with fluoropolymer, in a microwave radiation heated chamber, with means for controlling a microwave radiation generating means, such as a magnetron, in response to the presence of any solvent vapor in a collection container for rupture diaphragm discharged material from an extraction container or in exhaust gas from the chamber. The presence of the solvent in the collection container or exhaust gas is preferably detected by a semi-conductor gas sensor which decreases its electrical resistance in the presence of solvent vapors, thereby increasing its voltage and thus controlling operation of the magnetron, turning it off when solvent vapor (and a potentially explosive gas mixture) is present.      Also described are other explosion prevention means, including a fluoropolymer sheet covering a chamber ceiling and ceiling light, and a process for safely extracting organic materials, utilizing the described apparatus.
