Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a closure cap, a container and to a closure cap and corresponding container in combination.  Closure caps and corresponding containers having continuous or intermittent screw threads to engage each other when the cap and the container are in the closed position are known.  However, the cap has been known to back off from the container when subjected to vibration and general movement during transit and handling.  As shown in Figure 1 of the drawings, screw threads 14, 22 of a cap 2 and container 4 respectively each have sufficient alternate ridges 16, 27 and indentations 18, 28 over at least part of their length so that when the cap 2 and container 4 are in a closed position at least one ridge on one screw thread can  engage an indentation on the other screw thread.

Abstract: ELECTRICAL TEST EQUIPMENT HOUSING            Abstract of the Disclosure A waterproof housing for electrical or electronic test equipment with an opening at the rear for equipment and having a flap at the front, the flap hinged upwardly to open and close an aperture for operating or viewing instruments of the equipment.  Ideally, two identical housings may be joined rear-to-rear to form an assembly with a partition between them to close the openings and seal equipment inside one of the housings.  Movement of the flap is desirably frictionally resisted to allow it to be located in any desired position.  With the flap closed, a gap is formed between flap and housing for passage of wiring from the equipment.  Preferably, the housing has inner and outer skin layers which are relatively resiliently movable and a compressible foam may be between skin layers.                             -i-

Abstract: Abstract of the Disclosure In a print hammer mechanism in which an elongated, resilient hammer element mounted at a fixed end thereof has an opposite free end thereof selectively released from a retract position for impact of a dot imprinting element carried by the free end of the element, an improved magnetic circuit is provided for use in release and retraction of the hammer element.  The improved magnetic circuit includes a pair of elongated pole pieces of like configuration having back ends thereof mounted on opposite sides of a rare earth magnet and tips at the opposite front ends thereof disposed adjacent the free end of the hammer element to form a pair of gaps therewith. Improved magnetic properties are provided by the presence of two gaps, the close proximity of the tips so as to minimize the high reluctance magnetic path through the hammer element and the maintenance of a small air gap between one of the tips and the hammer element when the element is in the retract position in contact with the other tip to facilitate quick release of the hammer element.  The magnetic characteristics are even further improved by the physical design of the magnetic circuit which minimizes fringing magnetic fluxes and which utilizes a pair of magnetic coils, each of which is mounted on a different one of the pole pieces adjacent the tip thereof.  The use of two coils provides for substantially complete cancellation of the magnetic fields in both gaps upon energization to provide for quicker release of the hammer element from the retract position.

Abstract: ABSTRACT OF THE DISCLOSURE            A wood chip rechipping method and apparatus are provided wherein a slotted, cylindrical drum rotates about a concentrically mounted rotatable anvil rotor having a plura-lity of arms, each of which has a blade at its out extremity.          The drum and anvil rotor arms rotate in the same direction, but at different speeds.  The rotating apparatus induces centrifugal force on the wood chips to position them against the inner periphery of the drum where the blades on the rela-tively faster rotating anvil arms shear off a chip slice having a predetermined thickness.  This shearing action continues until each chip has been rechipped into slices capable of pas-sing through one of the drum knife slots and into the discharge outlet.

Abstract: Abstract of the Disclosure:     A similarity calculator for calculating a set of similarity measures S(A(u, m), Bc)'s according to the technique of dynamic programming comprises an input pattern buffer for successively producing input pattern feature vectors of an input pattern A to be pattern matched with reference patterns Bc , an m-th input pattern feature vector .alpha.m at a time.  The similarity measure set is for a set of fragmentary patterns A(u, m)'s defined by a common end point ? and start points ?'s predetermined relative to the end point ?,  Scalar products (.alpha.m??jn) are calculated between the m-th input pattern feature vector and reference pattern feature vectors ?jn of an n-th reference pattern Bn and stored in a scalar product buffer.  Recurrence values are calculated according to a recurrence formula for each end point ?, rather than for each fragmentary pattern set, and for each reference pattern Bn to provide a similarity measure subset S(A(u, m), Bn)'s, with a recurrence value for each reference pattern feature vector ?v calculated by the use of the scalar product (.alpha.m??v) and recurrence values calculated for a previous end point (m - 1) and for at least three consecutive reference pattern feature vectors preselected relative to that reference pattern feature vector ?v.  Instead of the scalar product, it is possible to use any one of other measures representative of a similarity or a dissimilarity between an input pattern feature vector and a reference pattern feature vector.
