Abstract: ABSTRACT OF THE DISCLOSURE   A battery has a metallic component the inner surface of which is in contact with the battery electrolyte and the outer surface of which is not in contact with the electrolyte.  To prevent undesired corrosion a mask is placed over a portion of the inner surface in order to electrochemically inactivate the portion of the inner surface covered by it.  Although the metallic com-ponent having the mask may be the positive electrode or a terminal, preferably it is the negative electrode and preferably the negative electrode is a metallic foil such as zinc, lead, magnesium, or aluminum or alloy thereof.  The outer surface of the metallic component opposite the mask may be exposed to the air.      An electrical lead may be connected to the outer surface of the metallic component opposite the mask.  Where the mask is applied to the inner surface of an electrode, the mask may contain metal or a metallic compound of a chemical composition compatible with the electrode in order to compensate for the loss of electrochemical activity at the surface of the electrode covered by the mask.

Abstract: ABSTRACT OF THE DISCLOSURE           Augmentation of aerodynamic lift for a given amount of power in STOL operation of a V/STOL aircraft is achieved by combining the unique features of a lifting body with those of a "jet flap", i.e. an aerodynamic mechanism in which a slipstream is directed over a deflected flap.  Specifically, a movable flap is located on the trailing edge of the lifting body, and a tiltable rotating blade propeller, which propels the aircraft in the normal manner in cruising, may be tilted, in low-speed flight, in order to direct air toward the leading edge of the flap and over the upper surface thereof.  The movement of a large mass of air at a higher velocity over the upper surface of the flap maintains the air flow over the flap in an attached condition, and entrains and energizes the lower-velocity boundary layer on the airfoil forward of the flap, thereby producing an augmentation in lift.  As the trailing edge of the lifting body is located well behind the aircraft's center of gravity, the lifting body makes it possible for a conventional rotating blade propeller to be used efficiently and effectively to produce the jet flap effect.  The lifting body also lends itself especially to lift augmentation in that, for a given lifting surface area, the low aspect ratio of the lifting body gives rise to a much greater lift augmentation than would be afforded by a high aspect ratio surface,

Abstract: ABSTRACT OF THE DISCLOSURE         A method of cutting sheet material with an automati-cally controlled cutting machine having a reciprocating cut-ting blade utilizes a schedule of auxiliary or supplemental machine motions to modify the basic or fundamental motions of a cutting blade and the sheet material under selected cut-ting conditions.  The supplemental motions and corresponding conditions are determined in advance by means of cutting improvement tests and are recorded in a schedule correlating the motions and corresponding conditions.  During subsequent cutting operations, the special motions are selectively ex-tracted from the schedule as the corresponding cutting condi-tions arise, and the motions are then employed to improve the overall cutting process.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides fastening means for a safety belt comprising a locking tongue adapted for being attached to one end of a safety belt, a locking case adapted for being attached to the other end of the safety belt, a locking flap displaceably supported by said case for selectively engaging said locking tongue to lock the same in said case and for releasing the locking tongue, a spring acting on said flap for urging the flap to a locking position in which the locking tongue is engaged by the flap means, and an expeller movably mounted in the case for expelling the tongue from the case with the tongue released from the flap.  A push button acts on the flap for displacing the flap to a released position, in opposition to the spring, in which the flap is released from the tongue. the push button includes a cam having a cam surface on which the flap is engaged under the action of the spring means.  The push button is displaceable to cause the flap to ride up on the cam surface and release the flap from engagement with the tongue.  The cam surface has an upper profile which has a sloping concave curve in a direction away from the push button and a lower portion provided with a slot in which the flap means is engaged in the locking position. The cam also has a lower planar portion which slidably rides on the locking case.  The expeller includes a projection for passing beneath the raised flap to support the flap while the tongue is being expelled by the expeller and to hold the flap in a raised position when the fastening means is not engaged.  In this manners the risk of faulty operation is substantially reduced.

Abstract: ABSTRACT OF THE DISCLOSURE            Coal is transported by forming a first aqueous slurry of carbonaceous and ash fine particles of at least 60 percent water by weight.  A free-flowing liquid lyophilic to carbonaceous fine particles in coal and lyophobic to water and ash fine particles in coal is added to the first slurry to form a mixture where less than 20% and preferably less than 10% by weight of the free-flowing liquid and the carbonaceous and ash fine particles of coal is free-flowing liquid.  The mixture is then agitated to preferentially agglomerate carbonaceous fine particles in the coal to form discrete agglomerates, while the ash fine particles in coal remain substantially unagglomerated in the mixture.  The discrete agglomerates of carbonaceous fine particles are then separated from the aqueous slurry and dispersed in a carrier liquid preferably of water or petroleum base to form a second transport slurry.  A stream of said second transport slurry is pumped typically through a pipeline from the point of formation to a point of destination, where the discrete agglomerates of carbonaceous fine particles of coal are separated from the carrier liquid and preferably pelletized.

Abstract: FOLDING MECHANISM FOR A MULTIPLE SECTION           AGRICULTURAL IMPLEMENT               ABSTRACT OF THE DISCLOSURE           A multiple section agricultural implement having laterally inner and outer wing sections on laterally opposite sides of a central section for relative folding movement about longitudinal axes by hydraulically powered folding mechanisms. The outer wing section is folded from an extended working posi-tion in which the wing sections are in horizontal alignment to an inverted position above the inner wing section and the inner wing section is folded to an upright position relative to the central section.  The folding mechanism for folding the outer wing section relative to the inner wing section includes a pair of links interconnected at their upper ends by a lost motion connection.  The lower ends of the links are connected to laterally spaced points on the outer and inner wing sections in spaced relation to the longitudinal pivot axis of pivot connec-tion between the sections.  The hydraulic jack of the folding mechanism is mounted on the inner wing section and is pivotally connected to one of the links.  The inner wing section is con-nected to the central section for pivotal movement from its extended working position to an upright position by a hydraulic ram mounted on the central section and connected to the inner wing section by a lost motion connection.  The lost motion connections permit the implement sections to float relative to one another during use of the implement thereby assuring proper position of the tools when traversing uneven ground.  The hydraulic jack of the folding mechanism between the outer and inner wing sections includes a clevis which presents a shoulder in abutting relation to the upper, slotted end of the link connected to the outer wing section when the latter is folded to approximately an overhead balanced position.  This abutting relationship, which continues to be present as the outer wing section is folded from its overhead balanced position to its inverted transport position, prevents uncontrolled movement of the outer wing section when the latter swings through its balanced overhead position.
