Abstract: VORTEX TYPE SOLIDS-LIQUID FLOW MIXER                 ABSTRACT OF THE DISCLOSURE     An apparatus and method for mixing liquid or drilling mud with solids is disclosed.  The apparatus provides first and second concentric housings which are utilized as mixing chambers.  An inlet passageway is tangentially connected to the inner housing for feeding a slurry material to be mixed with solids axially fed into the same housing.  A discharge port is further provided and connected to an outer housing for tangentially discharging the homogeneous mixture of slurry and solid materials from the outer mixing chamber at high velocities to an elevation above the inlet.  The method for mixing includes tangentially feeding the slurry into the mixing chamber, mixing the slurry with solid materials through the use of centrifugal force, shear forces and spill-over from the inner chamber to the outer chamber, and finally tangentially discharging the mixture from the outer chamber.

Abstract: ABSTRACT OF THE DISCLOSURE          In a kinetic sculpture apparatus, the lower end of a pendulum provides a scribe having a tapered tip that penetrates the surface of a bed of fine, particulate material to make an intricate pattern in the bed whose configuration is determined by the location of the pendulum's primary horizontal axis, the position from which the pendulum is released, and the depth of penetration of the tip of the scribe.  The suspension system for the pendulum includes an arch which spans a pair of standards disposed on opposite sides of the receiver that contains the bed of material, in order to maintain the primary axis of the pendulum at the same elevation as the pendulum swings to thereby assure that the depth of penetra-tion will be uniform.  The pendulum assembly is mounted above a baseplate by a ball and socket connec-tion which permits the entire assembly to be tilted in any direction to move the at-rest point of contact of the scribe away from the center of the bed to any quadrant or region thereof where a subpattern is to be sculptured.  Additionally, the receiver is inde-pendently rotatable about a vertical (or slightly inclined) axis through a selected angular displace-ment to permit the sculpturing of angularly spaced repeat patterns.  A highly stable suspension is pro-vided by a disc-shaped rocker element having a central slot therein through which the arch extends, the arch (Docket 384) having a V-shaped portion receiving the element in an upright attitude to define the primary axis of the pendulum.  Bed shaping is provided by a dish-shaped cover for the receiver having a con-vex lower surface.

Abstract: THERMAL-MAGNETIC CIRCUIT BREAKER                     ABSTRACT OF THE DISCLOSURE     The present invention relates to circuit breakers of a par-ticular class, namely, the type in which a toggle is manually erected to drive a "heart" as a unit for closing the circuit breaker.  The "heart" includes a contact arm, an actuator, and overcurrent releasable latch means which collectively form a nor-mally latched unit.  Under excess-current conditions, the latch means releases the actuator, and contact arm then opens the circuit.   The latch means includes a conventional bimetal fixed at one end to the contact arm.  The bimetal carries a pivoted latch lever, and is surrounded by a core-and-armature unit adjacent its secured end, for operating the latch lever in response to high overcurrents.  High magnetic trip sensitivity is achieved in a construction wherein the whole electromagnet moves with the con-tact arm, without resort to a current-carrying coil for the elec-tromagnet.

Abstract: ABSTRACT OF THE DISCLOSURE   A system for the electrical treatment of spinal curvature through the exercise of selected spinal muscles.  A probe having a blunt, muscle-penetrat-ing tip is fitted with a sleeve such that its tip extends from the sleeve. A helical electrode is mounted on an elongated tool capable of imparting a rotational force to the electrode while allowing a disengagement with the electrode in the direction of its longitudinal axis.  The probe is inserted in the paraspinal muscles and is removed while leaving the sleeve within the muscle.  The electrode-tool assembly is inserted through the sleeve and the electrode secured in the paraspinal muscles by a rotational force applied to the tool.  After electrode securement, the tool is withdrawn from the sleeve and the sleeve withdrawn from the muscle leaving the electrode secured with-in the muscle.  Needle electrodes may be employed to stimulate the paraspinal muscles at several sites to establish those sites at which the induced muscle contraction provides maximum correction of the spinal curvature and the blunt probe tip may be provided with an electrode for muscle stimulation at varied penetration depths to establish the optimum depth for securement of the helical electrode.  The electrodes are connected by leads to a receiver cir-cult implantable beneath the patient's skin and operable to receive Rf modulated stimulation impulses transmitted  through the skin.  The impulses are developed by a patient operated RF transmitter with a cyclic on and off stimulation and rest periods so that stimulation of the muscles may take place while the patient relaxes or sleeps.

Abstract: FAST-FILL MASTER CYLINDER                  ABSTRACT OF THE DISCLOSURE         A fast-fill master cylinder includes a stepped bore within a housing to movably receive a pair of pistons.  One of the pistons cooperates with a large diameter portion of the stepped bore to sub-stantially define a fast-fill chamber and also cooperates with a small diameter portion of the stepped bore and the other piston to substantially define a primary chamber.  A reservoir communicates fluid to the fast-fill chamber and the primary chamber,  The one piston carries a sealing member cooperating with the small diameter portion to close the primary chamber from the reservoir when the one piston is moved during a brake application.  The one piston defines a metering land adjacent the sealing member and also includes at least one passage leading from the fast-fill chamber to the sealing member.  During a first stage of braking fluid pressure generated in the fast-fill chamber in response to movement of the one piston is communicated to the primary chamber via the passage.  At this time the metering land forms a restriction so that substantially all of the fluid communication from the fast-fill chamber to the primary chamber is by way of the passage.  During second stage of braking the metering land is aligned with a port opening to the reservoir so that fluid pressure within the fast-fill chamber is gradually vented to the reservoir in response to movement of the one piston. The sealing member defines a radial outer portion in alignment with the metering land and a radial inner portion in alignment with the one passage.  A retainer is biased toward the one piston to urge the sealing member in fluid-tight engagement with the piston at a radial location intermediate the metering land and the one passage.

The moisture content of the dessert compositions ranges between 48% and 65%.  The comestible base is prepared by forming an uncooked blend comprising from about 25% to 65% by weight of the blend of citrus juice vesicles, from about 7% to 45% of a nutritive carbohydrate sweetening agent, from about 1% to 5 of an ungelatinized starch, from about 0.1% to 0.4% of water-soluble pectin, from about 8% to 60% by weight of water and sufficient non-volatile edible organic acid to provide the blend with a pH between 2.5 and 5.5.  The blend is then cooked to a viscosity (190°F.) between 7,000 and 10,000 cp. and a moisture content between 30% to 60%.  An aerated frozen dessert is prepared by aerating the mixture of these ingredients to a density of 0.2 to 0.95 g./cc. and then statically freezing the acrated mixture.
