Abstract: MOUNTING SPACER DEVICE FOR CAPACITOR                   Abstract of the Disclosure A sheet of material wrapped around a rolled capacitor section has a plurality of fingers extending outwardly from one side of the sheet.  The sheet is generally rectangular, and has dimensions such that the sheet encompasses at least a major portion of the cir-cumference of the capacitor section. The fingers extend from the sheet such that capacitor sections of substan-tial diameter variation are accommodated in a standard container size.  The fingers bend enough to allow inser-tion of the section and the spacer into the container, but remain urged against the inner surface of the con-tainer, thus holding the section in place against vibra-tion.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for upgrading commercially available titanium, zirconium or hafnium powder typically containing chloride contaminant characterized by the step of contact-ing the metal powder with an inert gaseous plasma (such as the arc heated stream of an arc heater) for a sufficient time to effect physical separation of metal and contaminant salt.  By operating the  arc heater  at temperatures  in excess of the boiling point of the contaminant salt (e.g. above 1686°K for NaC1) the purification can be assisted by vaporization of the salt.  After quenching and cooling the upgraded metal powder,  any residual contaminant salt on the surface of the metal can be removed by water washing.          The upgraded metal powder produced is useful in fabricating high density metal alloy parts by the blended elemental powdered metallurgical process.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an injection molding system with core ring gating which is used for making products with an opening through them formed by the valve pin.  The system has a melt passage which conveys pres-surize melt from a molding machine through a manifold to a bore in a gate insert, through which it flows along around the valve pin to the gate.  The valve pin has a head portion extending from a reduced neck portion.  The gate and the opening through the cavity are in alignment and substantially equal in diameter and the head portion of the valve pin fits closely through them into a bore in the ejector side of the mold.  Actuating mechanism drives the valve pin forwardly to the open position in which the reduced neck portion extends past the gate into the cavity to allow the pressurized melt to flow into the cavity.          The valve pin is then retracted to the closed position on which the head portion closes off the gate. One portion of the head portion is hollow to form an insulative air space and another portion adjacent the tip end is filled with a beryllium copper plug.  This structure provides the advantage for large diameter valve pins of improving the cooling rate in the closed position.  The air space reduces the mass of the head portion of the valve pin and reduces the flow of heat into the head portion.  The highly conductive plug increases the transfer of heat away from the head portion to the cooled mold platen.

Abstract: ABSTRACT A vertical container holds and treats particulate material, such as comminuted cellulosic fibrous material like wood chips.  The container in-cludes a vertical interior wall, an open top, and a discharge outlet at the bottom.  A top interior wall structure directs particulate material to a first false bottom concentric with it.  The first false bottom is mounted for oscillation with respect to the vertical container and discharges particulate material through a discharge opening in the generally conical bottom thereof into a second false bottom structure.  The second false bottom structure also includes a generally conical bottom with a discharge opening, and is also mounted for oscillation with respect to the container.  Steam is preferably introduced into the container to effect steaming of the particulate material within it, and the container is held at super-atmospheric pressure.

Abstract: ABSTRACT        In a method of manufacturing for a railway switch-point concrete sleeper blocks of varying lengths and having different number of attachment means located in mutually different positions for the attachment of rails to said blocks there is used a plurality of steel matrices (2; 102) whose respective lengths correspond to the desired lengths of the various sleeper blocks and which exhibit detachably mounted dowels (3; 109). The matrices are placed end to end in an elongate mould bed with the dowels facing upwardly, whereafter reinforcing lines (5) are tensioned and concrete (11) is east into the mould bed and permitted to harden. The thus formed coherent concrete body, whose length may exceed 30 meters, is then removed from the mould and the matrices (2; 102) removed and the dowels (3; 109) remaining cast in the concrete block. The concrete body is then cut into sleeper blocks of desired length. The dowels (109) are accurately mounted in predetermined positions in frame members (111) affixed to the matrices (102). Upon casting and hardening of the sleeper blocks the frame members (111) are disengaged from the matrices (102) and the in-cast dowels (109) for renewed use in a subsequent casting operation. The invention also relates to a matrix array for use in the described method.          (Figs. 1 and 8)

Abstract: ABSTRACT OF THE DISCLOSURE           A cutting die is provided with scrap ejection provisions for removing scrap from the die.  The ejection provisions are particularly effective for ejecting elongate scrap from elongate openings such as slots which are formed in carton blanks and the like, the blanks being produced from sheet material, such as corrugated board.  The ejection system includes resilient ejection members located between two parallel cutting rules, which members eject or push out the scrap from between the rules in an asymmetrical manner, exerting more force along one edge of the scrap than the other.  This causes    the scrap to twist and be more easily ejected.  An additional ejection member is located outside one of the cutting rules to cause a portion of the blank to deflect to further aid in the scrap ejection.

Abstract: ABSTRACT           Improvements in a full resolution image A are effected with an economical use of computer processing equipment and time by determining a field of improvement functions derived from processing a coarse representation of the original full resolution image.  The coarse representation B is subjected to lightness field analysis to obtain an improved coarse image C, from which a coarse improvement field D is extracted by subtracting the original coarse representation.  To obtain a full resolution improvement field E, the coarse improvement function is smoothly expanded by interpolation to the dimensions of the full resolution image.  By modifying the original full resolution image field A with the values of the full resolution improvement field E, an improved full resolution image is obtained.
