Abstract: ABSTRACT         In a snowplow of the type having a forwardly mounted plowblade which is reversible for left hand or right hand operation, the plowblade is a composite assembly of blade members comprising a fixedly mounted scoop blade and a deflector pivo-tally mounted so as to be tiltable about an axis perpendicular to the scoop blade.  Hydraulic cylinders for tilting the de-flector about its axis are cooperatively coupled to a pair of hydraulic cylinders for rotating the plowblade between its left hand and right hand operative positions, the hydraulic connections being such that when either end of the plowblade is brought to a trailing position the corresponding end of the deflector is raised.

Abstract: ABSTRACT OF THE DISCLOSURE         The improved method of the present invention involves the removal of lipid inhibitors from Limulus amebocyte lysate to increase the sensitivity and quality of the lysate.  The method comprises intimately contacting, as by mixing and stirring, Limulus amebocyte lysate with a selected binary liquid solvent system for a time sufficient to draw water into the solvent system from the lysate and to effectively extract and denature the lipid inhibitors in the lysate. The ability of the binary solvent to draw in water from the lysate and form, in effect, a new tertiary system is the important factor in this methodology. The method of water drawn into the solvent is controlled by the amount of polar solvent in the solvent system. After this extraction and denaturation, the lysate is then separated from the solvent system and recovered in purified from of increase sensitivity.

Abstract: METHOD FOR THE EXTRUSION OF TUBULAR FILMS     ABSTRACT          The present invention relates to a method for the extrusion of tubular thermoplastic films, in particular films produced from polymers such as high density polyethylene, polypropylene, and the like.  The method comprises coextrusion of the polymer in the form of a tube which has adhered to its surface, another polymer which is characterized by having a significantly higher melting point than the melting point of the first polymer tube.  The tubular films produced in this manner exhibit improved physical properties including a reduced tendency for rupturing or splitting in the machine or longitudinal direction when stresses are applied to such films.

Abstract: PROCESS AND APPARATUS FOR CASTING      ROUNDS, SLABS AND THE LIKE                        Abstract A process and apparatus for casting semi-finished metal products in which a molten-metal-proof-plunger (27, 100, 161, 163) is disposed near the top of a cavity (26, 162, 164) in a permanent mold (20, 150), a reservoir (36, 203) of molten metal is created and maintained over the plunger, and the plunger is caused to descend in the cavity at a con-trolled rate so that the molten metal (35) enters and fills the cavity above the plunger.  When the plunger reaches the bottom of its descent, a cast product of uniform cross sec-tion is formed.  As the cast product cools and solidifies, the plunger is preferably used to exert an upward force to the casting which may cause the top of the casting to project slightly out of the mold as it cools.

Abstract: ABSTRACT OF THE DISCLOSURE           A multiple speed ratio power transmission mechanism for an automotive vehicle adapted to be mounted in a transverse position with respect to the fore-and-aft centerline of the vehicle includes a torque input shaft having input gearing fixed thereto.  A first countershaft has gearing journalled thereon meshing with the torque input gearing, and synchronizer clutches adapted to be moved selectively to produce a driving connection between the input shaft and the countershaft.  A second countershaft has a fifth forward speed gear in meshing engagement with a gear on the input shaft and a synchronizer clutch that can be moved to produce a driving connection between the input shaft and the second countershaft.  A differential gear establishes a driving connection between both countershafts and each of two drive wheel axle shafts.  First and second shift fork rails are adapted for axial and rotary movement to produce engagement and release of the synchronizer clutches.  A shift selector controls the shift shaft and has a relay lever for transferring the motion of the selector shaft directly to the first shift rail, indirectly to the second shift rail through a first bellcrank, and indirectly to a reverse idler through a second bellcrank.  An interlock sleeve is mounted on the first shift rail and provides a selector pin for selective engagement directly and indirectly with each of the three shifting forks.  A blocking sleeve surrounds the interlock sleeves and prevents engagement of the first shift rail with the unselected shift forks.

Abstract: File No. 694 P/12 CA    ABSTRACT OF THE DISCLOSURE     METHODS AND APPARATUS FOR TRANSFERRING ELECTRIC CHARGES OF DIFFERENT SIGNS INTO A SPACE ZONE, AND APPLICATION TO         STATIC ELECTRICITY ELIMINATORS     In a supersonic nozzle, a current of compressed air charged with humidity is expanded to produce an aerosol of ice micro-particles. A corona discharge is maintained at the neck of the nozzle at the tip of a tapered electrode by a high alternating current voltage supply connected between the electrode and the nozzle body. The alternately positive  and negative ions produced by the discharge are trapped by the ice micro-particles and ejected by an orifice at the front of the nozzle out of the enclosure in the direction of a space zone the concentration in charges of different signs of which it is desired to raise. The electric supply compri-ses a capacitor in the circuit between the electrode and a conductive guard ring which is embedded in the body of the nozzle behind the insulating surface thereof. Thus fluxes of positive and negative particles which are overall balanced are obtained at the exit of the nozzle. The apparatus is well adapted to the elimination of static charges of elec-trified bodies.
