DEFINITION

Classification: 73/152.45

Electronic processing or electronic recording:

(under subclass 152.44) Subject matter including either a device which works by the emission, the behavior, or the effect of electrons and wherein the device either (a) operates on data pertaining to the determination of the characteristic of the borehole, the casing, or the drill rigging, or (b) makes a permanent record of the determination of the characteristic of the borehole, the casing, or the drill rigging.

SEE OR SEARCH THIS CLASS, SUBCLASS:

152.53, for an apparatus for making a determination of a characteristic of a borehole, a casing, or a drill rigging by measuring pressure combined with means for recording the determination being made.

152.62, for an apparatus for making a determination of a characteristic of a pump especially adapted for use of a borehole or a drill rigging and including a device for making a record of the determination of the characteristic of the pump.

346, Recorders, appropriate subclass for a recorder for recording the operation of machines and particularly

33+, for a recorder combined with external recorder operating means including a well logging means and subclasses 112+ for

a graph-type recorder. 360, Dynamic Magnetic Information Storage or Retrieval, appropriate subclass for magnetic storage and retrieval of arbitrarily variable information which is retained in a storage medium by variation of a physical characteristic thereof and wherein relative movement between a storage element and a source of information, a transducer, or a receiver is required.

364, Electrical Computers and Data Processing Systems,

422, for an application of electrical computers and data processing to well logging wherein detail of the computer or the data processing system combined with only nominally recited sensor are recited.

365, Static Information Storage and Retrieval, appropriate subclass for a recording apparatus not requiring relative movement between a storage element and a source of information, a transducer, or a receiver.

369, Dynamic Information Storage or Retrieval, appropriate subclass for a process of or an apparatus for the storage and retrieval of arbitrarily variable information which is retained in a storage medium by variation of a physical characteristic thereof and wherein relative movement between a storage element and a source of information, a transducer, or a receiver is required.
