Abstract: APPLICATION OF                   ROBERT C. WHITEHEAD, JR.               FORCE TRANSDUCING CANTILEVER BEAM          AND PRESSURE TRANSDUCER INCORPORATING IT     ABSTRACT OF THE DISCLOSURE    A differential pressure and process pressure transducer includes a semiconductor cantilever beam, a diaphragm, a spacer, and a back plate.  The diaphragm, spacer, and back plate, fabricated from glass, quartz or silicon, or a combination of those materials, are bonded together at their peripheries to form a cup.  The ends of the beam are bonded, respectively, to the supported periphery of the diaphragm and to an intermediate deflecting portion thereof, whereby pressure forces within the cup are transmitted by the diaphragm to the beam.  Piezoresistive elements are diffused into the surface of the beam to produce an electric signal in accordance with the strain produced in the beam as the result of the pressure forces.  In one embodiment, the cantilever beam is a flat plate.  In another embodiment, the beam includes a portion at the mounting end that is massive relative to the stress sensitive portion of the beam.  The juncture of the massive mounting portion and the stress sensitive portion is an abrupt step, whereby a precise fulcrum for the stress sensi-tive beam portion is provided.  In another embodiment, a relatively massive beam portion also is provided at the movable end of the beam remote from the mounting end.  Other embodiments include a glass wire or a spring inserted between the movable end of the beam and the deflecting portion of the diaphragm.

Abstract: ABSTRACT OF THE DISCLOSURE:           This invention is concerned with a skinning machine for skinning fish fillets.  This machine comprises a rotatable skinning roller provided in its circumferential surface with a plurality of depressions, a skinning knife provided with a serrated or sinuate cutting edge arranged at a uniform spacing from the circumferential surface of the roller, and a presser surface for pressing skin, severed from fillets by the knife, against the circumferential surface of the roller. Advantageously, the presser surface may be provided by a surface portion of the knife and the knife may be mounted to be pivotable against a spring force about an axis parallel to the axis of rotation of the roller, abutment means being provided to set a minimum spacing of the knife from the circumferential surface of the roller.  Such a machine permits to prevent a splitting-up of the fillets in operation.

Abstract: ABSTRACT OF THE DISCLOSURE A block type cutting tool with insert blades of the throw away type, the block having pockets for mounting the inserts and clamps movable into the pockets for locking the inserts in place. Each insert includes a groove formed centrally thereof and running generally parallel to one of the locating surfaces of the pocket for engaging a tip portion of the associated clamp. The groove is wider than the tip so that locking of the clamp first causes the tip to wedge the insert into the pocket, following which the tip engages the lip of the groove to firmly draw the wedged insert against a locating surface. This arrangement more positively holds the insert against displacement when the tool is withdrawn, provides a perceptible stop indicating the clamp is fully locked, and, in cases where radial insert adjustment is provided, helps to guide the insert to prevent cocking.

Abstract: Abstract of the Disclosure A light source illuminates particles migrating in an electrophoresis chamber under the influence of a reversing polarity electric field applied between a pair of spaced elec-trodes which are in the form of thin conductive layers deposited on opposed end portions of the chamber.  The light reflected from the particles migrating along the stationary layer of the chamber is imaged onto a circumferentially arranged grating on a trans-parent rotating disk and modulated thereby.  The modulated reflected particle light image is then applied to a photomulti-plier tube which in response produces a special output signal which is subsequently applied to a frequency translating circuit where it is heterodyned down to the zero frequency region and offset relative to a reference frequency such that the heterodyned signal has a frequency content which is related to mean mobility and a polarity with respect to the offset reference frequency which serves as an indication of the polarity of the charge of the particles migrating in the chamber.  A Real Time Analyzer or a frequency tracking circuit may be employed to convert the translator output signal to a mobility histogram or to an accurate measurement of mean mobility, respectively.
