US Patent:

42465761, Jan 20, 1981

Filed:

Apr 26, 1979

Appl. No.:

6/033704

Inventors:

Donald F. Grieve - LaHonda CA

Assignee:

Krebs Engineers - Menlo Park CA

International Classification:

G08B 2100

US Classification:

340606

Abstract:

An apparatus and method for monitoring the operation of centrifugal cyclones. Sensing means is disposed in the underflow spray discharge of a cyclone and is connected to electronic sensing circuitry adapted to produce a signal or alarm response when the cyclone ceases to operate in a normal manner. In one embodiment the apparatus and method employs a plurality of cyclones connected to receive feed material from a common manifolding means. Abnormal functioning of one cyclone of the group is immediately indicated by visual or audible alarm means and thereafter its sensing means may be disabled to permit the sensing circuitry to continue to be effective for the remaining cyclones. Delay means is incorporated in the circuitry to prevent a response when the abnormal condition is of short duration. One form of sensing means employs a probe which extends into the normal underflow discharge spray. Another form employs a paddle and switch assembly, with the paddle extending into the normal discharge spray.

Abstract:

A form roller compensator is provided for use in mounting a printing form roller in a publication printing apparatus in proper orientation relative to a printing cylinder. The form rollers in a printing machine control the amount of ink transferred to the printing surfaces of a printing cylinder for printing alphabetic and numerical characters and pictorial illustrations. The invention allows the amount of ink transferred by printing form rollers to be varied to compensate for the inordinately heavy or light supply of ink which results from pressure variations of the form rollers against impression cylinders. These pressure variations are caused by thermal expansion or contraction of the various rotating cylinders involved.
