COUNTING MECHANISMS; COUNTING OF OBJECTS NOT OTHERWISE PROVIDED FOR (counting by measuring volume or weight of articles to be counted G 01 F, G 01 G; adaptation of counters to electricity meters in electromechanical arrangements for measuring time integral of electric power or current G 01 R 11/16; computers G 06 C to G 06 J; counting electric pulses H 03 K; counting characters, words or messages in switching networks for transmission of digital information H 04 L 12/08; metering arrangements in telephonic systems H 04 M 15/00)

Note

This subclass covers:

–

stepping or continuously-moving mechanical counters operated through one or more inputs applied to the lowest order mechanically or electrically;

–

counting systems involving applications of either mechanical, electrical, or electronic counters.

Design features of general application

Housing (for measuring instruments in general G 01 D)

for driving the stage of lowest order (with variable ratio of drive G 06 M 1/38)

producing continuous revolution of the stage, e.g. with gear train

for actuating the drive

by electric or magnetic means

by fluid means

for transferring a condition from one stage to a higher stage (with variable ratio of transfer G 06 M 1/38)

self-operating, e.g. by Geneva mechanism

requiring external operation, e.g. by electromagnetic force

specially adapted for denominations with unequal numbers in each stage, e.g. degrees and minutes of angle

for visual indication of the result of count on counting mechanisms, e.g. by window with magnifying lens

Drums; Dials; Pointers

Aligning means

for representing the result of count in the form of electric signals, e.g. by sensing markings on the counter drum

272

using photoelectric means

274

using magnetic means; using Hall-effect devices

276

using mechanically-actuated contacts

for zeroising or setting to a particular value

using heart-shaped or similar cams; using levers

Actuating means, e.g. magnet, spring, weight

using reset shafts

Actuating means, e.g. magnet, spring, weight

for varying ratio of drive or transfer mechanism, e.g. by using alternative counting trains

Counters with additional facilities (generating electric pulses at random intervals H 03 K 3/84)

for performing an operation at a predetermined value of the count, e.g. arresting a machine

with an additional counter train operating in the reverse direction

for printing or separately displaying result of count (display systems G 09)

for counting the input from several sources; for counting inputs of different amounts

for counting denominations with unequal numbers in each stage, e.g. degrees and minutes of angle (transfer mechanism therefor G 06 M 1/20)

for preventing incorrect actuation, e.g. for preventing falsification

for registering difference of positive and negative actuations

Counting of objects (in machines for making cigarettes A 24 C 5/32; in machines for shaping metal without removing material B 21 C 51/00; in printing machines or presses B 41 F 33/02; in office copying machines B 41 L 39/02; of axles of rail vehicles B 61 L 1/16; in packaging machines B 65 B 65/08; of objects conveyed through a pipe or tube B 65 G 51/36; entry or exit registers G 07 C 9/00)

Counting of objects carried by a conveyer

wherein objects ahead of the sensing element are separated to produce a distinct gap between successive objects

Counting of piece goods, e.g. of boxes

Counting of flat articles, e.g. of sheets of paper

wherein the direction of movement of the objects is changed at the station where they are sensed

Counting of flat overlapped articles, e.g. of cards

Counting of objects in a stack thereof

by using a rotating separator incorporating pneumatic suction nozzles

11/

Counting of objects distributed at random, e.g. on a surface

11/

using an electron beam scanning a surface line by line, e.g. of blood cells on a substrate

11/

with provision for distinguishing between different sizes of objects (investigating particle size in general G 01 N 15/00)
