Abstract: A sharpening machine for sharpening the cutting edges of instruments, particularly the curved inner cutting edges of dental instruments, to obtain an arbitrary wedge angle. A grinding disk is provided with both a plane surface and a radiused outer edge. A shaft extension extends above the plane of the grinding disk and serves to support the instrument as it is being sharpened. The longitudinal axis of the instrument is displaced away from the axis of rotation of the shaft extension by an offset distance equal to the one-half diameter of the shaft extension thereby determining an offset angle of the longitudinal axis of the instrument with respect to the grinding disk and thus the wedge angle of sharpening of the curved inner edge of the instrument. In order to facilitate the sharpening of the curved inner edge of the instrument, the outer edge of the grinding disk is formed with a radius shorter than the radius of curvature of the instrument.

Abstract: Disque optique (23) contenant des versions classées PG et R (soumises à l'avis des parents et réservées aux adultes) du même film cinématographique. Pour minimiser le stockage redondant de données, trois types de blocs de données vidéo sont stockés dans la même piste selon un mode entrelacé, les blocs du type A contenant des données spécifiques à la version A, les blocs du type B contenant des données spécifiques à la version B et les blocs du type C contenant des données communes aux deux types de blocs A et B. Une série de codes et de pointeurs inclus dans chaque bloc permettent de lire tous les blocs communs sans lire les blocs qui contiennent des données spécifiques à la version non sélectionnée. La lecture des versions réservées aux adultes est automatiquement bloquée si un adulte (un parent par exemple) a actionné la touche du lecteur asociée à l'option de verrouillage parental. Ce disque peut contenir un logiciel spécial qui identifie les diverses versions du même film cinématographique lorsque le critère de sélection est différent d'une classification de film.

Title: Fuel temperature control
Inventor: HANNAH KEITH
IPC: F02M31/10
Filed: 1996-05-01
Granted: 1997-09-02
Abstract: An apparatus for controlling the temperature and pressure of liquid fuel supplied to a liquid coolant cooled internal combustion engine includes a metal block heat exchanger having a generally centrally aligned longitudinal bore extending generally longitudinally along a central axis between opposed first and second coolant apertures. The opposed first and second coolant apertures are adapted to receive opposed liquid coolant conduits, for transporting liquid coolant from the engine to a heat radiator, in releasable, liquid coolant communicating engagement therein whereby liquid coolant may be passed in a coolant flow direction between the opposed first and second coolant apertures through the longitudinal bore along a coolant flow path extending along and within the opposed liquid coolant conduits and the longitudinal bore. The heat exchanger includes at least one generally "U"-shaped fuel passageway looping between a fuel inlet aperture and a fuel outlet aperture in the metal block heat exchanger. The "U"-shaped fuel passageway is spaced apart from and straddles the centrally aligned longitudinal bore wherein a leg of the "U"-shaped fuel passageway communicates fuel passing between the fuel inlet aperture and the fuel outlet aperture in a counterflow fuel direction generally opposed to the coolant flow direction, wherefrom the fuel may be transported to the engine by a fuel conduit. The apparatus includes fuel temperature sensing means for determining the fuel temperature of fuel transported to the engine from the fuel outlet aperture and depending on the temperature, a coolant modulator regulates the coolant flow.

Abstract: A cryptosystem utilizes the properties of discrete logs in finite groups, either in a public key message exchange or in a key exchange and generation protocol. If the group selected has subgroups of relatively small order, the message may be exponentiated by a factor of the order of the group to place the message in a subgroup of relatively small order. To inhibit such substitution, the base or generator of the cryptosystem is chosen to be a generator of a subgroup of prime order or a subgroup of an order having a number of relatively small divisors. The message may be exponentiated to each of the relatively small divisors and the result checked for the group identity. If the group identity is found, it indicates a vulnerability to substitution and is rejected.

Abstract: A melt-blowing system and corresponding method are provided for making a nonwoven polymer filament blanket.          Subsequent to formation and blowing of the polymer filaments toward a receiving conveyor, a pivoting oscillating member is provided through which the filaments are blown.  Vertical oscillation of the oscillating member causes the flow direction of the filament stream to vertically oscillate thereby increasing the tensile strength of the nonwoven blanket in the in-line direction as a substantial number of the filaments become oriented in the in-line direction on the conveyor.

Abstract: Orthogonalization techniques are disclosed which can be used, for example, to improve subtraction of CDMA signals from a composite spread spectrum signal or to improve detection of CDMA signals from the composite spread spectrum signal. According to exemplary embodiments, a Gram-Schmidt orthogonalization process is used to modify signature sequences which are each associated with a particular CDMA signal in the spread spectrum composite signal. These modified signature sequences can then be used to spread correlations of the original signature sequences in the subtraction process or in the detection process to improve performance. Pre-orthogonalization according to the present invention, eliminates or mitigates multiple access interference.

IPC: G06V30/224
Filed: 1998-05-08
Granted: 2005-12-13
Abstract: A method of monitoring the condition of poles making up a transmission/distribution line network. A first step involves affixing to a pole a unique pole identifying code that distinguishes the pole from any other pole in the transmission/distribution line network. A second step involves inputting into a computer database data considered relevant to effectively monitor the condition of the pole. The database is indexed under the unique identifying code whereby the data is retrievable with reference to the unique identifying code. In order to speed up data entry, it is preferred that a data entry template of machine readable code be provided along with a scanner capable of reading the machine readable code.
