UHV (CLASS 438)
ultrahigh vacuum

ULTRAFILTRATION (CLASS 210)
Filtration of a solution or colloid, retaining a constituent of macromolecule dimension. See FILTRATION and MEMBRANE.

ULTRAVIOLET/INFRARED (CLASS 359)
Electromagnetic radiation immediately above and below the optical visible frequency spectrum is termed ultraviolet and infrared, respectively. This entire range of frequencies is encompassed by the term "light."

UNBALANCED CIRCUIT (CLASS 330)
A circuit having its conductors electrically unsymmetrical with reference to a potential plane. For example, a concentric line is ordinarily unbalanced, the outer conductor being ordinarily connected to ground.

UNBALANCED CIRCUIT (CLASS 333)
A circuit having its conductors electrically unsymmetrical with reference to a potential plane. For example, a concentric line is ordinarily unbalanced, the outer conductor being ordinarily connected to ground.

UNDERDRIVE (CLASS 475)
Mechanism wherein an output member* is driven at a slower rotational velocity than the rotational velocity of an input member*.

UNDESIRED OBJECTS (CLASS 171)
Trash, previously cut tops or foliage or other nonearth material accompanying the objects disclosed as intended to be removed from the earth and recovered.

UNEARTHING (CLASS 171)
This is the generic term for any of the various organizations for removing an object imbedded in the earth, at or near the ground surface as by digging or picking the object and separating it free from any substantial accumulation of earth, the separation being accomplished either simultaneously with or subsequent to the removal of the object from its position in situ in the ground.

UNEARTHING UNIT (CLASS 171)
An entity which includes all of the apparatus necessary to completely unearth a buried or partially buried object in its path regardless of the presence or absence of additional, similar entities in the same organization.

UNIFORM RESOURCE LOCATOR (URL) (CLASS 725)
An address for a resource on the Internet. URLs are used by Web browsers to locate Internet resources. A URL specifies the protocol to be used in accessing the resource (such as http: for a World Wide Web page or ftp: for an FTP site), the name of the server on which the resource resides (such as //www.uspto.gov), and, optionally, the path to a resource (such as an HTML document or a file on that server).

UNIPOLAR (CLASS 257)
An active solid-state electronic device in which only one type of charge carrier, positive or negative, is used to support current flow.

UNIPOLAR (CLASS 438)
An active solid-state electronic device in which only one type of charge carrier (i.e., positive holes or negative electrons) is used to support current flow.

UNIPOLAR TRANSISTOR (CLASS 257)
A transistor in which the source to drain current involves only one type of charge carrier.

UNITARY DOSAGE FORM (CLASS 424)
Denotes that form of medication supplied in a manner requiring no further weighing or measuring to provide the dosage; e.g., tablet, capsule, etc. Medicines in bulk form; e.g., powder, syrup, etc., are not included.

UNITARY DRIVE (CLASS 475)
Mechanism wherein an output member is driven at the same rotational velocity as an input member.

UNIVERSAL-BAR (CLASS 400)
A member that is part of a drive train of a typewriter, which member is driven by any of a multiplicity of elements and which member serves to drive any of a different multiplicity of elements. A universal-bar may be driven, for example, by a space-bar*, or by a character* key* element that causes imprint of a character and also drives the universal-bar either directly or via a type-bar* member or associated linkage. The universal-bar may then serve to drive a carriage-feed mechanism or a ribbon-feed mechanism or a character-counter mechanism or all these exemplary mechanisms concurrently.

UNSATURATED (CLASS 260)
Denotes the presence of a double or triple bond linking two adjacent carbon atoms, thus: >

UNSTRUCTURED DATA (CLASS 707)
A collection of data stored in a form that does not readily translate to a database. The most common form of unstructured data is text documents.

UNVOICED (CLASS 704)
Speech sounds produced by a turbulent flow of air created at some point of stricture in the vocal tract and usually lacking pitch.

UPPER-CASE (CLASS 400)
A capital letter, similar in appearance to this text, as opposed to lower-case*. The derivation of the terms upper-case* and lower-case is discussed in the definition of lower-case in this Glossary. See the definitions of character* and case-shift* in this Glossary for the forms of symbols that are imprinted when the case-shift mechanism is in the upper-case mode.

USAGE CONTROL (CLASS 726)
Subject matter includes means placing restrictions on computer and/or user use of applications

USER (CLASS 902)
A person interacting with the system* to perform a transaction* with a monetary fiduciary party. The user initiates the transaction by operating the terminal*.

USER DATA (CLASS 345)
Data other than address data, instruction data, or status data. (also see: Data)

USER DATA (CLASS 711)
Data other than address data, instruction data, or status data.

USER DATA (CLASS 714)
Data other than address data, instruction data, or status data.

USER PROTECTION/PRIVACY (CLASS 726)
Subject matter includes means for ensuring the state or integrity of information or data associated with a user.

UV (CLASS 438)
ultraviolet
