Abstract: COOLANT FLOW METERING DEVICE                     Abstract Two overlapping members subject to relative displacement and separated by a gap for spreading a pressurized fluid as a film over the overlapped member are provided with a metering device for providing an essentially constant fluid flow area irrespective of the size of the gap resulting from differences in relative displacement of the members. The metering devices comprise a flexible seal connected to one of the members, the seal being of such a length that it engages in sealing contact the other member under the influence of the pressurized fluid. Orifices of a predetermined size and number formed within the seal provide a generally constant flow area for metering the fluid prior to passage through the gap.

Abstract: TITLE    SEA SLED TOW LINE VECTOR SYSTEM     ABSTRACT OF THE DISCLOSURE         The tow line system permits a determination of the direction and magnitude of tow line forces on the underwater tow.  The response of the underwater tow to the tow line forces is also monitored.  The system is adaptable to any system capable of measuring forces and angles remotely and trans-mitting these values to the surface by means of electrical, hydraulic, or pneumatic signals.  The underwater tow can be any object which responds to the force of gravity and which is directed by one or more tow lines.  The system consists of symmetrically placed horizontal and vertical load cells, two each in number, at the base of an isosceles triangle formed by a chain or cable tow bridle, the vertex of which is connected by means of another cable or chain or combination thereof to the tow vessel which also houses the display console.  The under-water tow further contains a gravity oriented pitch angle detector whose plane is parallel to the bisector of the vertex of the tow bridle and whose zero index identifies the normal posture of the underwater tow when resting on a horizontal reference surface.  The vertical load cells are perpendicular to the horizontal reference surface and parallel to the direction of zero index of the pitch indicators.  The response of the under-water tow is compared to a level plane and any deviation of the underwater tow or the forces upon it is immediately detected.

Abstract: PROCESS FOR THE PRODUCTION OF HIGH PROTEIN WHEY PRODUCTS of which the following is  a specification.                     Abstract of the Disclosure A process for the treatment of whey to produce products containing whey protein to a desired predeter-mined level. Whey is subjected to treatment for removing a portion of its lactose content by lactose crystalliza-tion and the resulting mother liquor, which has a protein level higher than that of the original whey, is then sub-jected to ultrafiltration carried out in such a controlled manner as to produce a protein rich fraction having the desired protein content.  The process produces products standardized with respect to protein content, irrespect-ive of variations in the protein level of the source whey, which may vary from time to time.

Abstract: Abstract of the Disclosure Two-package polymeric compositions which form cured products having excellent stain and solvent resistance and having improved potlife comprise a polyepoxide and an addition interpolymer containing pendent salt groups formed by reacting carboxyl groups with a hindered amine and pendent amine groups formed by reacting carboxyl groups with an alkylenimine.         The addition interpolymer when mixed with the polyepoxide reacts to form a cured, hard, stain and solvent resistant material.  The stability of the mixed compositions, i.e., its potlife, is lengthened by utilizing a sterically-hindered tertiary amine to form the salt groups of the inter-polymer.  Stability of the addition interpolymer prior to mixing is improved by utilizing therein monomers which provide aminolysis-resistant groups in the interpolymer.

Abstract: ABSTRACT OF THE DISCLOSURE          The specification discloses a saw having a circular saw blade wherein a motor for driving the saw blade and a bearing for the saw blade spindle are mounted on a mounting frame which is positioned below a work table and can be raised and lowered in a pivoting movement about a horizon-tal pivoting axis parallel to the spindle axis.  The mounting frame is suspended in a tiltable cradle suspended in a circular work support which is flush with the top of the work table and is rotatably mounted in a cir-cular opening therein.  When the mounting frame is raised the saw blade will project through a slot in the support.  The mounting frame is operated by a thin bar projecting through the slot in the support and carrying a handle above the work table.  The bar is integral with a riving knife.  It is ro-tatably mounted about the saw blade axis, and it is connected to the cradle by a linkage formed by an articulated rod and the mounting frame.  Thereby the operating bar will maintain the same vertical position relative to the saw blade axis when lifted.  In fact, it will move along a path equi-distant to the path of the saw blade axis, and the length of the movement will be the same as that of the saw blade axis.

Abstract: Abstract of the Disclosure An actuator and actuator-orientator assembly orients aerosol cans in the proper position to spray a stripe of marking material.  An actuator having a generally cylindrical outer surface is adapted to be mounted on the valve stem of an aerosol can and in-cludes a spraying orifice and a pair of radially outwardly extending locating lugs.  The actuator-orientator is provided with a circular central opening into which the actuator is inserted and a pair of recesses which extend radially outwardly from the central opening for receiving the locating lugs of the actuator when the actuator is properly oriented.  The periphery of the central opening is defined by curved guide surfaces which extend upwardly from the recesses.  A guide surface extends from each side of each recess and meets a guide surface from the other recess at the midpoint of the arc which extends between the recesses.  When the actuator is inserted downwardly into the opening of the orientator and the lugs engage the guide surfaces, the actuator and aerosol can move down-wardly and rotate along the guide surfaces until the lugs are seated within the recesses.

Abstract: FILAMENT WINDING APPARATUS                  Abstract of the Disclosure A filament winding machine includes a servomotor connected to position a filament distributing carriage relative to a rotating mandrel to form a tubular member.          An incremental encoder is connected to the mandrel and produces a pulse related output per mandrel revolution.          An absolute encoder is connected to the servomotor and provides an absolute position number.  The encoders are sampled at a fixed rate.  A mathematical calculating circuit reads the incremental encoder and based on a predetermined movement design for the gear drive, the desired winding configuration and the like determines the proper position, which is compared to the absolute encoder reading to produce an error control signal to the servomotor.  A preselected sequence of actual position numbers and the corresponding calculated position numbers are continuously updated in a temporary memory.  The difference of succeeding pairs provides data for directly computing the rate at which the head is moving a proper position and thus also the data for computing actual acceleration or a deceleration of the head movement.  A microprocessor has proper programs with appropriate user specified parameters to produce various winding configura-tions.  The microprocessor provides the calculation of the proper position and determination of the drive signal.          Suitable optional control tables such as a cosine table may modify the calculated carriage position to produce any desired motion.  Rapid and continuous monitoring permits the system to anticipate necessary correction and thereby provide a continuous and low power level correction of heavy driven elements such as a filament winding head and carriage.
