Title: Dental curet and sharpening machine system
Inventor: SVANBERG GUNNAR K
IPC: B24B41/06
Filed: 1988-09-06
Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE         A dental curet and sharpening machine system has been developed for complete mechanical guidance of the instruments during the sharpening procedure.  Double-ended dental curets comprising cutting blades, shanks, and a handle have been designed so that regardless of the instrument's rake angle, the arc center of the toe on the face of the cutting blade which is to be sharpened lies on the longitudinal center axis of the instrument and at a constant distance from reference points on the instrument handle.  The sharpening machine comprises a base, an electrical motor with a rotating sharpening stone, and an instrument guide unit.  The instrument guide unit can position the blade face of a curet of any rake angle in a horizontal plane with the arc center of the toe on the blade's face coincident with a vertical axis about which the guide unit is swung while the blade edge is engaged with the rotating stone during the cutting procedure.  The invention comprises three aspects: 1) the curets; 2) the sharpening machine; and 3 ) the method of sharpening the curets.

Title: Method and apparatus for determining k-factor and depth measurements
Inventor: ULICH BOBBY LEE
IPC: G01S17/89
Filed: 1989-07-06
Granted: 1996-05-28
Abstract: A system is presented for the remote detection of the diffuse attenuation coefficient or K factor over very large areas and over relatively short time periods; and for determining depth in a body of water or other medium. In accordance with the present invention, a laser is used to generate short pulses of light with pulse widths on the order of nanoseconds.  The laser light is expanded by optics and projected into the water or other medium.  An intensified CCD (charge coupled device) camera is electronically shuttered after an appropriate time delay such that the image formed by the camera is composed of light backscattered by the water from a layer of range z and a thickness of .DELTA. z.  The signal detected by the camera is Si.  If several measurements of Si are made at known time delay differences such that the differences of range gates zi are also known, then K can be calculated.  The same apparatus can also be used to determine depth by measuring the time delay between the reflection from the surface of the medium and the reflection from the bottom of the medium.

Title: Generation and selection of novel binding proteins
Inventor: LADNER ROBERT CHARLES
IPC: C07K14/81
Filed: 1989-09-01
Granted: 1998-12-29
Abstract: In order to obtain a novel binding protein against chosen target, DNA molecules, each encoding a protein comprising one of a family of similar potential binding domains and a structural signal calling for the display of the protein on the outer surface of a chosen bacterial cell, bacterial spore or phage (genetic package) are introduced into a genetic package.  The protein is expressed and the potential binding domain is displayed on the outer surface of the package.  The cells or viruses bearing the binding domains which recognize the target molecule are isolated and amplified.  The successful binding domains are then characterized.  One or more of these successful binding domains is used as a model for the design of a new family of potential binding domains, and the process is repeated until a novel binding domain having a desired affinity for the target molecule is obtained.  In one embodiment, the first family of potential binding domains is related to bovine pancreatic trypsin inhibitor, the genetic package is M13 phage, and the protein includes the outer surface transport signal of the M13 gene III protein.

Abstract: "IMPROVED METHOD AND APPARATUS FOR     CUSTOMER ACCOUNT SERVICING"                   Abstract A method and an apparatus for retrofitting and extending or upgrading an existing customer account servicing system to provide for automated handling and processing of both incoming and outgoing calls. A mainframe computer or host (16) contains customer or potential customer account records. A plurality of operator terminals (12) allow the operators to converse with the called or calling party and make changes to the customer account information via a data terminal (12a4). A system controller (11), trunk interface unit (10), operator terminals (12) and cross-point switch or PBX (13) provide a retrofit to an existing system, a mainframe computer (16), to provide for automated handling and processing of both incoming and outgoing calls. The system controller (11) and terminals (12) use the same command and data format structure as that already in use by the existing system and software or programs of mainframe (16). The system controller (11) is transparent to the operation of the mainframe (16) and the operator terminals (12) and allows the system to be upgraded without the necessity of purchasing different software or programs for the mainframe (16). This invention is useful with both new and previously existing operator terminals (12). The system controller (11) monitors and handles both incoming and outgoing calls via the trunk interface units (10) and, when appropriate, causes the cross-point switch or PBX (13) to connect a selected trunk line (T) with an appropriate available operator terminal (12) and causes the customer account record to be displayed on the screen of the operator terminal.
