A dental floss holder is in the form of a box (20) with a drawer (22) in it. The bottom of the drawer includes a hub (38) which is spring biased to push a bobbin (24) mounted thereon toward an opposite side of the box. The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss. A result is that the bobbin does not unwind while ...

A control system for controlling automotive vehicle driving behavior has a parameter monitoring means for monitoring vehicular driving parameters, a vehicular driving environmental condition predicting means which predicts vehicular driving environmental condition based on generalized intelligence base which is common to all vehicles, a control output generating means for deriving a control output...

Sheet grippers 4, disposed on endlessly revolving chains 3 of a first gripper system A, grip the front edge of the sheet, with after-grippers 7, disposed on endlessly revolving chains 6 of a second gripper system B, gripping the rear edge of the sheet. The two gripper systems are phase-adjustably disposed with respect to one another to enable the feed of differently sized sheets. Gripper system B ...

A decanter centrifuge including a discontinuous screw conveyor having flights only within the generally cylindrical portion of the centrifuge bowl. A restricting disc is provided adjacent to the heavy phase material discharge ports such that the restriction contacts the build-up of heavy phase within the portion of the bowl where the flights are discontinuous.

In an electronic cash system, K sets of blind signature information are derived from secret information containing identification information of a user (200, 400), K/2 sets of them are opened and a bank (100) attaches a blind signature to the remaining K/2 sets of information. The user obtains a signed license from the blind signature. The user generates blind signature information from the licens...

The present invention provides a fiberglass composite which possesses outstanding armor properties. This ballistic resistant composite material employs high strength magnesia aluminosilicate glass fibers and phenol formaldehyde condensation product as the matrix resin. The composite is produced from sheet molding compound using little or no solvent.

A system for controlling an automobile transmission effects a gear change by disengaging synchronizing clutch means (R) for a present gear position, achieving a neutral gear position, and then engaging a synchronizing clutch (R) for a next gear position in response to a shift control signal. The automobile transmission has an actuator (A2) for selectively engaging and disengaging the synchronizing...

An angular rate sensor comprises a wafer (10) of silicon etched to form tines (5, 6) with teeth (14, 16) which are interdigitated. The tines (5, 6) are excited into oscillation in the plane of the wafer (10), by applying suitable drive signals to create electrostatic forces between the tines (5, 6). Rotation of the tines (5, 6) out of the plane of the wafer is detected by a suitable detector, such...

A biaxially oriented polyester film which is characterized as follows: (A) it is composed of an aromatic copolyester which is obtained with use of a germanium compound as the polycondensation catalyst, the copolyester having a melting point in the range from 210 to 245 DEG C and a glass transition temperature not lower than 50 DEG C, (B) it has a refractive index in the thickness direction in the ...

A method for production of an absorbent resin which comprises exerting a shearing force on a hydrated gel polymer having a cross-linked structure thereby obtaining a particulate hydrated gel polymer having a moisture content in the range of from 30 to 90% by weight, a polymerization ratio in the range of from 60 to 99.9% by weight, and an average particle diameter in a dry state in the range of fr...

Chemical vapor deposition method for producing a fine grained smooth growth surfaced diamond film on a substrate employs a hydrogen/hydrocarbon gaseous atmosphere containing an amount of nitrogen effective to inhibit the growth of the diamond grains deposited on the substrate.

The present invention relates to a user interface for a system for transaction processing between a computer-based server and a plurality of work stations, consisting, on the one hand, of three files which reflect the states of progress of the tasks allocated to the active device using this interface, namely the "new" file (40), the "current" file (50), and the "executed" file (60) stored in memor...

There is disclosed a biaxially oriented film formed of film forming composition comprising a polyoxymethylene polymer in which the major constituent of the main chains of said polymer each of consists substantially of repeating units of oxymethylene group @@CH2-O@@, said film being characterized in that, when said film is remelted at a temperature above the melting point of said film and the resul...

A sheet-form molded article constituted of 30 to 70% by weight of a fiber having a strength of 20 g/d or above and an elastic modulus of 500 g/d or above prepared from an aromatic polyamide of which 50% by mole or above is occupied by p-phenylene terephthalamide unit and 70 to 30% by weight of a fiber and/or film prepared from an aromatic polyester having a melting or softening point of 250 DEG C ...

The present invention provides crosslinked, spherical copolymer beads of methacrylic anhydride which are suitable as precursors for weak-acid and other ion exchange resins, affinity chromatography materials and other materials which require spherical polymers having reactive anhydride groups for their preparation. The present invention also provides a process for making such copolymers.
