Abstract: (Newman Case 3) ABSTRACT OF THE DISCLOSURE         The method and apparatus of the invention simultaneously induces the same variable frequency mechanical vibrations in a test part and a standard.  The vibrations of the two are converted to signals which are either displayed for comparison purposes or automatically analyzed for differences.  Advantageously, the signals are electrical signals providing spectra which are analyzed for differences in amplitudes produced by the signals.  Where the parts are separately supported, they are held with substantially the same force and are maintained against the vibration inducing mechanism with the same force.  Where accelerometers are used, they are held with substantially the same force against the vibrating parts.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of making high density powdered metal compacts and also a method for making high density powder metal sintered products is disclosed.  With respect to the compacts, iron powder of a coarse or fine configuration is mixed or coated with a low melting metal additive selected from the group consisting of tin, copper-tin, copper-lead, or lead in a percentage by weight of 2 5 of the admixture.  The admixture is subjected simultaneously to both heat (at a temperature level such that the low-melting alloy is in a liquid phase) and pressure which is in the range of 10-30 tsi.  Upon relief of heat and pressure, the agglomerated or compacted product will possess an increased density in excess of 80% and an improved hardness and strength level.      With respect to a sintered product, the powder metal is selected to have a line particle size (average range of about 4-5 microns) and the powder is dry impact coated by ball milling with a low-melting additive such as tin, copper-tin, copper-lead or lead; the coated particles are warm briquetted and subjected to a sintering operation whereby the resulting product has a minimum density of 97% or more.

Abstract: 5.1.1980                    1                PHD 79-035 ABSTRACT: "Device for determining local absorption differences in an object".     During computer tomography examinations, ring-like artefacts occasionally occur because the X-ray source becomes hot, so that the X-ray focus changes its position in space. Because the distance between the detector and the diaphragm which stops the radiation beam is several times larger than the distance between the X-ray focus and the diaphragm, the shifting of the radiation beam on the detec-tor is even greater. If the detector consists of detection elements which are not exactly identical, it may occur that the sensetivities of the detection elements apparently change with respect to each other due to such a shift, the reconstruction then giving rise to said artefacts. In ac-cordance with the invention, the position where the radia-tion beam is incident on the detector is measured and the diaphragm for the stopping of the radiation beam is read-justed so that the radiation is each time incident in the same area.

Abstract: 2220-11a ABSTRACT                A tool which loops the end portion of the outermost convolution of a spiral wire binder around the neighboring next-to-the-outermost convolution while the convolutions of the binder extend through the perforations of a stack of paper sheets and the binder is located in a preselected position has a knife which trims the outermost convolution and thereupon bends the end portion of the outermost convolution to a position of parallelism with and proximity to a stationary surface.  A looping device which is mounted at the forward end of a rotary reciprocable shaft is thereupon caused to engage the bent end portion in response to forward movement of the shaft and to loop the bent end portion by moving it along the surface and around the neighboring convolution in response to rotation of the shaft.  The shaft is rotatable and reciprocable and the knife is movable by a set of coaxial cams which complete one revolution in order to effect trimming of the outermost convolution, to thereupon effect bending of the end portion of the trimmed convolution and to ultimately effect looping of the bent end portion.  The cams are rotatable by a rack and pinion drive through the medium of a one-way clutch.

Abstract: ABSTRACT OF THE DISCLOSURE          A composite container capable of accommodating an internal vacuum environment within a tubular body of spirally wound paperboard or similar paperbase materials.  A hermetically sealed liner is provided coextensive with the interior of the tubular body and adhesively secured thereto throughout substantially the full extent of the interior surface of the body.  The liner is spirally wound, defining a spiral overlapped seam with the overlapping edge portion including an underfolded edge flap folded about a fold line prior to adhesive engagement with the overlapped edge portion. The seam fold thus formed has the interior thereof in direct communication with the paperbase body and is capable of ballooning inward, through the entire length thereof, upon generation of a vacuum atmosphere with the container.  The vacuum atmosphere can thus be accommodated without affecting the structural integrity of the container.  Lines of weakness are specifically avoided in the body plies by staggering the ply seams, offsetting the ply seams from the liner balloon seam, and providing at least some of the body plies with overlapped deckled or skived edges.

Abstract: ABSTRACT     A method of preparing oligopeptides from collagen is dis-closed. Collagen containing material is treated with an aqueous solution of a member selected from the group consisting of an alkali earth metal hydrox-ide, an alkali metal hydroxide and mixtures thereof in the presence of an agent which prevents overswelling of the collagen. The treatment removes substantially all of the hair and fat from the collagen. The remaining non-collagenous material is removed by treating the dehaired and defatted col-lagen with an aqueous solution which acts as a solvent for the non-collagen-ous material.  The collagen is neutralized and residual salts are removed therefrom. The collagen is heated under pressure in the presence of water to hydrolize polypeptide chains to form oligopeptides having a molecular weight of between about 5,000 and 20,000. The recovered oligopeptides are particularly useful as a trophic agent for  feeding animals.
