Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for emulsifying sausage batter and the like wherein sausage batter to be emulsified is first gravity fed from a hopper into the inlet of a comminuting chamber. The batter is then impelled radially outwardly into a rotating centrifugal trap which is adapted to centrifugally remove impurities such as metal particles and to direct the material downwardly through a series alternately rotatable and non-rotatable perforate rings.  The interaction of the rings comminutes and emulsifies the batter as it passes therethrough, whereupon it exits vertically from the lowermost of a series of rings and is swept by rotating blades into a tangentially disposed discharge conduit.

Abstract: MECHANICAL ENGINE GOVERNOR WITH VARIABLE LIMITING SPEED SETTING MEANS          Abstract of the Disclosure A limiting speed mechanical engine governor has a speed responsive fuel decreasing mechanism opposed by a high speed spring, the effective force of which controls the maximum governed speed of the engine.  A speed adjus-ter, such as an air actuated piston, is arranged to act against the operative end of the high speed spring to controllably reduce its preset speed setting force and thus provide for controlled reduction of the maximum governed speed of the engine.  A control system is dis-closed for use on a vehicle, such as a diesel engine powered truck, to permit using the variable maximum speed capability of the governor as a road speed control for the vehicle or to provide a reduced controlled engine speed for operating engine driven accessories when the vehicle is stationary.

Abstract: Abstract Or the Disclosure A Bourdon tube is situated down hole in an oil well or the like, and has attached thereto a coded wheel which rotates an amount determined by the sensed down hole pressure.  The wheel has a number of transparent and opaque concentric bands thereon which form a gray code pattern indicative of a selected range of pressures.  A plurality of radiant energy transmitters are radially positioned on one side of the wheel in optical alignment with each of the respective bands.  A plurality of radiant energy sensors are positioned and aligned in a like manner on the other side of the wheel for sensing the passing or blocking of the radiant energy by the respective bands formed on the wheel.  Included is a digital logic circuit controlled by a temperature responsive oscillator which provides timing signals having a frequency determined by the sensed down hole temperature.  The logic circuit responds to the signals sensed by the sensors for providing a binary coded outout signal indicative of the sensed down hole pressure and temperature, wherein the sequence of the bits in the signal is indicative of the pressure and the frequency of the signal is indicative of the temperature.

Abstract: ABSTRACT OF THE DISCLOSURE         An insoluble cross-linked polypentapeptide is totally synthesized by preparing two modified linear polypentapep-tides patterned on the polypentapeptide from the pentapeptide (Val1-Pro2-Gly3-Val4-Gly5) one of the repeating peptide sequences contained in tropoelastin, the precursor protein of the core of the elastic fiber of the vascular wall, and by cross-linking the modified polypentapeptides.  One of the intermediate polypentapeptides is modified by replacing a portion of at least one of the amino acid residues with the residue of an amino acid having more than one amino function and the other is modified by replacing a portion of at least one of the amino acid residues with the residue of an amino acid having more than one carboxyl function, to provide free amino groups on the one intermediate and free carboxyl groups on the other for interreaction in the presence of a suitable cross-linking agent.         The resulting cross-linked insoluble polypentapep-tide is elastomeric in nature and capable of calcification by withdrawing calcium ions from a serum medium, thus making it useful as a calcifiable matrix for the formation of an artificial bone structure.  The calcifiable material can be treated to make it useful in artificial vascular wall formation.

Abstract: ABSTRACT OF THE DISCLOSURE         In an element for supporting and bracing sealed glazing units or other plate-like bodies in a surrounding frame, there is described an improved element which may be resiliently deformed to thereby enable the element to be used in the install-ation of glazed windows or other plate like units of varying sizes.  Known supporting elements are not so resiliently deform-able and are therefore not adaptable for use with window units of varying widths.  In this invention, two parallely extending edge ribs are interconnected by a web which may be resiliently and elastically deformed to change the distance between the edge ribs.  After being deformed, the web, due to its elasticity, tends to restore itself towards its original dimensions, thereby gripping opposite sides of the supporting frame.
