Title: Dental filling band
Inventor: DIN FRANKLIN M
IPC: A61C5/12
Filed: 1991-05-09
Abstract: A dental matrix band that is flexible and bondable to resin based restorative materials. This matrix band will permanently bond to the filling and the tooth. It becomes a permanent part of the composite restoration and may be wholly retained, partially retained, or completely removed depending upon the needs of the dentist, patient and the specific purpose for which this band is used. The dentist forms a prepared cavity. The thin, flexible composite matrix band is then inserted between the tooth and the adjacent tooth. The band is firmly held against the tooth with the surface of the band passively abutting the adjacent tooth. A bonding agent is applied to the appropriate tooth surfaces, the cavity and the band. The agent is cured, the prepared cavity is filled with a composite resin, the resin is cured and the excess portion of the band is removed.

Title: Amperimetric measurement with cell electrode deplating
Inventor: MINA CHARLES J
IPC: G01R27/22
Filed: 1991-05-28
Abstract: In an amperimetric measurement apparatus comprising an amperimetric cell having a pair of electrodes arranged for contact with a solution, a potential difference is established between the electrodes, and a corresponding electric current is conducted in a forward direction through a current path which includes the electrodes and the solution.  An output corresponding to the current indicates the concentration of a solute in the solution.          The electrical charge passing through said cell in response to said potential difference is monitored by an integrator.  The forward current is interrupted repeatedly and a reverse electric current is imposed on the cell during the interruptions of forward current. The magnitude and duration of the reverse current are regulated in response to the electrical charge flow corresponding to the forward current, so that the net flow of charge through the cell over a time period including an equal number of intervals of forward and reverse current intervals is substantially zero.          Consequently, ionic contaminants, which tend to be plated onto cell electrodes as a result of the forward current are removed substantially completely by deplating, without the risk of producing inaccurate measurements by placing the cell in a reverse charging condition.

Patent CA-2071883-A1 (CA)
Inventor: BAKER BRUCE D
IPC: A61B6/00
Filed: 1991-08-27
Abstract: A multipath laminography systems which enables multiple locations of an object (14) a be viewed in sequence without requiring mechanical movement of the object is disclosed. The object is interposed between a rotating X-ray source (32) and a synchronized rotating detector (16), A focal plane (74) within, the object is imaged onto the detector (16) so that a cross-sectional image of the object is produced. The X-ray source is typically produced by deflecting an electron beam (30) onto a flat transmission target anode (24). The target anode (24) emits X-ray radiation (34) opposite the location where the electrons are incident upon the target. The electron btam is produced by an electron gun (18) which includes X and Y deflection coils (22) for deflecting the electron beam (30)  in the corresponding X and Y directions. Deflection voltage signals (60, 62) are applied to the X and Y deflection coils (22) and cause the X-ray source to rotate in a circular trace path. A DC voltage applied to the X deflection coil (22) will cause the circular path traced by the X-ray source (32) to shift is the X direction by a distance proportional to the magnitude of the DC voltage. This in turn will cause a different field of view (70, 72); which is displaced in the X direction from the previously imaged region, to be imaged within the satoe focal plane (74) in the object. A DC voltage applied to the Y deflection coil (22) will cause the circular path traced by the X-ray source (32) to shift in the direction by a distance proportional to the magnitude of the DC voltage. This in turn will cause a different field of view (70, 72), which is displaced in the Y direction from the previously imaged region, to be imaged within the same focal plane (74) in the object (14). Identical changes in the amplitudes of the voltage signals applied to the X and Y deflection coils will change the radius of the X-ray source path, thereby resulting in a change in the Z level of the imaged focal plane (74).

Title: Radio receiver capable of suppressing a frequency drift in an intermediate frequency
Inventor: KOJIMA TATSURU
IPC: H04B1/40
Filed: 1992-06-26
Abstract: A radio receiver for receiving a radio signal includes a counter which determines an eventual intermediate frequency of an amplified signal based on a reference signal as a count datum. A frequency controller controls a reference frequency of the reference signal according to the count datum. A reference oscillator is controlled by the frequency controller to produce the reference signal. When receiving a radio signal by a double superheterodyne method, the radio receiver gives the eventual intermediate frequency to the amplified signal. In the amplified signal, the frequency controller suppresses an eventual frequency drift which results from frequency drifts of a first local oscillation and a second local oscillation. The radio receiver may also be a single superheterodyne receiver.
