Abstract: Abstract A centrifugal pump for liquids containing solid material, the impeller of which has two or several vanes.  In a bottom projection the leading edge (3) of the impeller (1) vane (2) is curved backwards in relation to the rotating direction of the impeller.  The angle between the leading edge (3) and the outer edge (5) is obtuse in a meridian and a bottom projection.  The outer end (10) of the leading edge of the vane is positioned behind a shoulder (9) provided with grooves (11), which cooperates with the vanes of the impeller.  The form of the leading edge causes the fibres and the sticks to be conveyed towards the point of the vane where they are crushed by the combined effect of the groove and the vanes.

Abstract: Abstract The disclosure illustrates and describes a sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are effective through the mandrel assembly on which the container bottom closures are formed and sealed.  This is accomplished by forming longitudinal channels through each mandrel and connecting same to separate compartments formed within the hub, and providing means for communicating a suitable sterilant fog through respective compartments and channels at the station where each bottom-formed container is stripped from its respective mandrel.  The usual fast stripping action tends to create a vacuum within the container which aids the dispersement of the fog onto the entire inside surface of the container, sterilizing it prior to the subsequent filing operation.

Abstract: IGNITION COIL CORE AND METHOD OF MAKING IT Abstract of the Disclosure A laminated core for an ignition coil is made from E shaped and bar shaped laminated members.          The E shaped member has equal length outer legs and a shorter center leg with oblique surfaces on the inner free ends of the outer legs.  The bar shaped member has oblique surfaces at the ends thereof adapted to engage the oblique surfaces of the first member when the second member is oriented perpendicu-larly to the center leg of the first member and further to bend the outer legs of the first member outward to generate a restoring spring force as the second member is advanced toward the center leg to reduce the air gap.  A coil assembled on the center leg is used to monitor a physical parameter indicative of a desired magnetic or electrical characteristic as the air gap is reduced and the members are fixed together when said characteristic is obtained.  The angles formed by the oblique surfaces of the first member with a surface of the center leg are smaller before assembly and no greater after assembly than corresponding angles of the corresponding oblique surfaces of the second member.

Abstract: ABSTRACT The invention relates to faujasite-containing compositions in which the original hydrogen or monovalent forms are ion exchanged to their polyvalent form and then thermally activated to promote dehydration and dehydroxylation of the faujasite while maintaining substantially the same zeolite content. The resulting compositions containing faujasites substantially in their dehydrated/dehydroxylated state have been found to have surprisingly high selectivities and capacities for the separation of air into nitrogen and oxygen.

Abstract: Abstract of the Disclosure An improved splicing apparatus has a splicer head comprising a pair of opposed upper and lower traveling carriages each of which supports an idler roller, a nip bar which is swingable on its carriage between a ready position downstream from its corresponding idler roller and a web preparation position at the front of the splicer head and means for pushing the nip bar towards the opposite nip bar when both carriages are in their advanced positions.  A knife carriage located on the head between the two nip bar carriages retracts when either nip bar carriage retracts to permit the nip bar on the opposite carriage to be swung to its web preparation position.  The knife carriage supports a knife which can be actuated momentarily to urge it from a normal retracted position to an advanced position wherein it intercepts one of the nip bars when that nip bar is in its splicing position against the opposite nip bar.  The present splicer facilitates preparation of a ready web in a quick convenient and safe manner and it also produces splices between webs having little or no tails in a reliable and efficient manner.

Abstract: ABSTRACT: Position sensor.         The force-sensitive position sensor or writing tablet is composed (for each of the two coordinate directions) of two layers of parallel extending light conductors having a spacing of 0.1 mm or less, the distance between the two layers being approximately 5 µm. By locally exerting a force on the carrier material in which the light conductors ar embedded (for example), by means of the tip of a stylus), the light conductors are geometrically deformed. These deformations cause a variation of the optical coupling between the two locally deformed conductors, thus causing a detectable transfer of light (variation) from one conductor to the other. By connection of one layer to a light source and the other layer to a suitable detector, a force-sensitive position sensor can be constructed by means of electro-optical means.
