Abstract: AUTOMATIC AIR LEAK TESTING APPARATUS AND METHOD FOR MULTIPLE CHAMBERED CONTAINERS              SUCH AS BATTERIES            ABSTRACT OF THE DISCLOSURE         Containers, such as batteries, battery cases and the like, are moved along a first conveyor to a leak test-ing station, above which is located an assembly having means matable over the openings in the top of the con-tainer.  The container is supplied with air at a given pressure, and metering means notes pressure change.  If the container does not leak, the container advances from the testing station along the conveyor.  If a leak is detected, a reject means ejects the container transversely from the testing station along a second conveyor, thereby isolating leaky containers for further processing.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for drawing, or blanking and drawing, a flat metallic piece into a cup shape.  A blanking punch, blanking die, draw die, movable stripper and a spacer are mounted on the stationary bed of a press.  A pressure pad and draw punch are carried by the ram of a press.  The pressure pad is positioned to contact first the blanking punch, then to contact the movable stripper and push it solidly against the spacer.  As the ram continues its downward movement, the pressure pad collapses with respect to the ram by virtue of its connection to a piston operating in a cylinder in the ram containing controllable air pressure.  The maintenance of a predetermined pressure pad-draw die gap during the draw prevents wrinkling, and the maintenance of the controlled pressure on the pressure pad prevents thinning and subsequent clipping of ears.  The edge of the blank which is captured between the pressure pad and draw die is gradually pulled radially inward as the die approaches the bottom of its stroke and the wrinkling and thinning and clipping of ears of the blank which would take place during this pulling is prevented.          On the upstroke of the ram air is injected into the draw punch to assist in stripping the finished cup from the punch, and the blanking punch and mounting plate are raised by springs, and the movable stripper raises the scrap upward for removal.

Abstract: OPTICAL SYSTEM FOR SCANNING  DURING RECIPROCAL MOTION         ABSTRACT OF THE DISCLOSURE           An optical system for strip scanning of an object in both directions of relative reciprocal motion between the object and the optical system.  The object is first scanned in one direction, then the optical axis between object and image is rotated 180° for scanning in the reverse direction.          Properly oriented images are thus projected onto a photo-receptor during both directions of scan.

Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus is disclosed for simultaneously performing electro-phoresis separations on a plurality of slab gels containing samples of protein, protein subunits or nucleic acids.  A reservoir of buffer solution is divided into three compartments by two parallel partitions having vertical slots spaced along their length.  A sheet of flexible, electri-cally insulative material is attached to each partition and is provided with vertical slits aligned with the slots.  Slab-gel holders are received within the slots with the flexible material folded outwardly as flaps from the slits to overlay portions of the holder surfaces and thereby act as electrical and liquid seals.  An elongated, spaghetti-like gel containing a sample of specimen that was previously separated by iso-electric focusing techniques is vertically positioned along a marginal edge portion of the slab gel.  On application of an electrical potential between the two outer chambers of buffer solution, a second dimensional electrophoresis separation in accordance with molecular weight occurs as the specimen molecules migrate across the slab gel.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved method of distributing catalysts in coal comprising oxidizing the coal and ion-exchanging the active sites thus formed with a cation which exhibits catalytic activity when used in a subsequent coal conversion process. The ion exchange may be accomplished simultaneously with or subsequent to the oxidation step.  After the ion exchange the coal can then be subjected to conversion via a gasification process.  Ion exchange with the alkali and alkaline earth metal cations is particularly effective when the coal is subsequently converted via a gasification reaction.  Incorporation of the cations into the coal via the method of this invention results in increased conversion rate and, generally, higher conversions to more desirable products. The method is particularly effective in the conversion of subbituminous and higher ranking coals and is most effective in processes wherein bituminous coal is converted.

Abstract: HOSE CLIP     ABSTRACT OF THE DISCLOSURE           A hose clip wherein the housing is made of an originally flat sheet metal blank and has a tubular section for the shank of a rotary screw mating with one end portion of a band whose end portions extend through the tubular section between the thread on the shank and a flat bottom wall of the tubular section.  The head of the screw has a tubular portion which surrounds one end portion of the tubular section so as to hold such end portion against radial and/or axial movement relative to the screw whereby the head cannot penetrate into and cannot expand the tubular section while it rotates in a direction to tension the band around the end portion of a hose or an analogous structure.  The tubular portion may be integral with the remaining portion of the head, it can  be bonded to such remaining portion or it may be rotatably mounted on the shank adjacent to the remaining portion of the head.  Since the head cannot penetrate into the housing and the screw cannot pivot with reference to the housing, the shank of the screw can apply to the band a very pronounced tensional stress to tighten the looped intermediate portion of the band around a hose or the like.          An extension of the housing which is disposed substantially radially or tangentially of the shank is provided to prevent tilting of the housing as a result of rotation of the tubular section with the shank when the screw is rotated in a direction to tension the band.  Teeth between two neighboring surfaces of the tubular section and the head reduce the likelihood of excessive tensioning of the band in that the teeth oppose-continuous rotation of the shank by causing the head to ratchet with respect to the adjacent end portion of the tubular section.          The teeth can also prevent or oppose rotation of the screw in a direction to reduce the tensional stress upon the band.
