Abstract: YOKE SHAPED SEPARATION CHAMBER WITH FEED AND FLOW CONTROL MEANS     ABSTRACT A pneumatic material separator having adjacent generally vertical primary and secondary ducts, a generally vertical discharge duct communi-cating with the tops of the primary and secondary ducts and an apparatus for creating upwardly moving columns of gas in the ducts is disclosed.          All of the ducts are of equal width and have substantially rectangular cross sections.  An air foil at the junction of the primary and discharge ducts is present to minimize the turbulence of gas moving therebetween.  A star feed apparatus introduces particulate material into the primary duct where the material is separated, by the upwardly moving column of gas, in-to an upwardly moving lighter fraction discharged through the discharge duct and a downwardly moving heavy fraction discharged through the primary duct.  The secondary duct may be located beneath a portion of the discharge duct where gas velocity is reduced and may be oriented to receive downwardly falling objects so that the heaviest particles of the lighter fraction fall into and are discharged through the secondary duct.  The secondary duct is positioned so that a column of gas moving upwardly therethrough, moves in the same general direction as the column of gas in the discharge duct so that the columns merge at a small acute angle to minimize turbulence.  A venturi formed at the top of the secondary duct accelerates the flow of gas therethrough, which flow is adjustably controlled by a damper inside the duct.

Abstract: SLIP CAST ARTICLE MANUFACTURING METHOD                   ABSTRACT OF THE DISCLOSURE          A method of forming a slip cast article is disclosed.          The slip cast article is formed in a casting volume of a form-ing mold, which mold has a portion thereof formed of a meltable organic material.  The vehicle of the casting slip used to form the article is drawn off to a level which provides a consolidated casting in the casting volume which contains sufficient vehicle that the casting is resistant to shrinkage.  The consolidated casting and the organic mold portion are then surrounded with a porous, liquid drawing media.  A high humidity of the vehicle of the casting slip is maintained about the consolidated casting surrounded by the porous, liquid drawing media.  The consolidated casting and surrounding liquid drawing media are heated while the high humidity of the vehicle is maintained to a temperature which causes the meltable organic material to melt.  The porous, liquid drawing media then draws the melted material away from the con-solidated casting.  After the meltable mold portion has been withdrawn from association with the consolidated casting, the high humidity vehicle is removed from association with the con-solidated casting and the casting is permitted to dry.

Abstract: A B S T R A C T      When metal inert gas (MIG) welding is carried out at normal atmospheric pressure, the electrode is made positive with respect to the workpiece because the use of a negative electrode gives little penetration.  In undersea welding, as the pressure increases the arc stability and metal transfer in MIG welding become erratic and there is copious fume evolution.  According to the present invention, MIG welding at pressures greater than 7 bars is carried out with the electrode negative with respect to the workpiece and with an electrode wire of diameter not greater than 1.4mm; the slope of the power supply, as seen from the welding arc, is preferably between 6 and 15V/l00A, which is higher than the 3 to 4V/l00A used in positive-electrode MIG welding at normal atmospheric pressure.

Abstract: CLOSED TORUS TIRE Abstract of the Disclosure A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel.  The reinforcement ply is continuous cir-cumferentially of the tire and axially in the crown and sidewalls.  The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores.  The tire is made without use of a building core of any kind, thus avoid-ing the cost and difficulty of removing such core from the completed tire.  The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve.  An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge.  The one edge is then moved inward and axially under the other edge to form the lapped splice.    The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.

Abstract: SAFETY-STRAPLIKE CONNECTING MEMBER                 ABSTRACT OF THE DISCLOSURE A structure for securing one end of a safety strap to a ski or a component fixedly mounted on the ski.  The other end of the safety strap is presumed to be secured to the skier by any conventional means.  The structure by which the safety strap is secured to the ski structure enables the strap to hold the ski to the skier should the ski become disconnected from the skier while travelling on a chairlift or at slow speeds.  However, this same structure will facilitate a release of the strap from engagement with the ski structure should the ski be pulled away from the skier with a sufficient magnitude of force, such as will occur during falls at high speeds.  The thereafter released ski will be stopped by, for example, a ski brake mechanism mounted on the ski.

Abstract: PRESSURE LIMITED FOR HYDRAULIC BRAKE BOOSTER                 ABSTRACT OF THE DISCLOSURE         The present invention relates to an improvement in a hydraulic brake booster, and in particular, covers a structure which provides a pressure limiter for the hydraulic brake booster.  The booster comprises a housing which defines a pressure chamber and supports a control valve and a piston.  During braking the control valve cooperates with an actuator to move relative to the housing so as to communicate pressurized fluid to the pressure chamber and the piston is movable in response to the pressurized fluid within the pressure chamber to effectuate braking.          In order to limit the level of pressure of pressurized fluid communi-cated to the pressure chamber a ring is disposed within the housing in cooperation with the control valve.  The ring cooperates with the control valve to define a differential area which is exposed to pres-surized fluid to generate a force opposing movement of the control valve so that communication of pressurized Fluid to the pressure chamber is limited.  In a preferred embodiment the ring is integrally formed with a sleeve to form a differential area responsive to the pressurized fluid communicated to the pressure chamber and the sleeve cooperates with a resilient member to bias the control valve to a non-braking position.
