Abstract: Abstract of the disclosure.      An apparatus for determining the depth position of venous thrombi in the lower extremities utilizes a unique property in 125I. This resides in the fact that in approximately half of all disintegrations, two photons are emitted simultaneously.          These two coincident photons have, like separately emitted photons, an energy of approximately 28 keV. A scintillation detector perceives the coincidently emitted photons as one photon of an energy of 56 keV. The quotient between the number of separately emitted photons and the number of coincident photons may thus be determined. This quotient constitutes a parameter which is greatly dependent on the distance between the detector and the source of radiation, whereby there is obtained a possibility of determining the depth of the thrombus.

Abstract: MEASURING METHOD AND APPARATUS                 ABSTRACT OF THE DISCLOSURE    The invention includes a method and apparatus for improving the accuracy of optical or electrical position measuring apparatus wherein movement of one object relative to another is measured. One known system employs primary and secondary windings each comprising a multiplicity of series-connected conductors arranged on adjacent faces of relatively movable members of insulating material. In another system an optical Moire fringe pattern is moved in correspondence as regards extent and sense with the movement with the object and the number of fringes displaced from a fiducial line are counted. The improvement is applicable to either system and includes placing a series of parallel lines or parallel conductors on the scale or movable object at an angle with respect to the path of movement of the object and placing another set of parallel lines or parallel conductors on the slider or reader followed by providing for controlled movement of the scale transversely of the path of movement of the object to vary the "count" of the lines or conductors on the scale and those on the slider or reader in order to compensate for machine or scale error and render the resulting operational "counts" accurate with respect to the actual movement of the object. Adjustable scale engaging clips are employed to permit the controlled lateral adjustment of the scales.

Abstract: SEALING COVER AND METHOD FOR RESEALING AN INTRAVENOUS CONTAINER     ABSTRACT     A laminated self-destructing sealing cover (10) has a container cover area (14) and pull tab (16). Protrusions (18) extend from the outer edge of the cover area (14) to promote proper use of the cover (10). A slit (20) may be into the protrusion (18) or the outer edge of the cover area (14) to promote tearing of the cover upon removal of a container.  The bottom side of the cover (10) engaging the container top is a central disk (24) surrounded by an annular ring of adhesive material (28).  Adhesive material (28) is self destructed upon removal of the cover (10) from the container to leave a telltale ring (28A) on the container top.  In an alternate embodiment, an area of perforations (60) may be made in the area of the cover (10) for engaging the container top to leave a telltale trace of the cover on a container top upon removal of the cover (10).

Abstract: ABSTRACT OF THE DISCLOSURE A floating wedge is described for facilitating the mounting of an indexable insert in a pocket of an indexable cutting tool. The floating wedge includes a main body member having opposed leading and trailing surfaces. The leading surface of the main body member and the trailing surfaces of the swivel plate member are disposed in abutting relationship and are provided with complementary configurations, thereby enabling the relative slidable movement between the members such that orientation of the leading surface of the swivel plate member relative to the trailing surface of the main body member may be adjusted.  The adjustability between the members enables full and equal contact pressure to be established between the floating wedge, the indexable insert and the walls of the insert pocket, thereby eliminating localized stresses and preventing insert failure.  In a preferred embodiment of the subject invention, the trailing surface of the main body member and the associated wall of the pocket of the cutting tool area provided with complementary configurations.  The latter arrangement allows for the relative movement between the leading surface of the swivel plate member and the walls of the insert pocket, thereby increasing the range of motion of the floating wedge.

Abstract: ABSTRACT OF THE DISCLOSURE     Error detection and correction method and apparatus for use with digital data signals, which have been coded using cross-interleaving error correction codes with added check words prior to transmission, employ a plurality (k) of syn-drome word signals (S0...Sk-1)  that are generated by multi-plying one block (VT) of the received digital data signals with a parity check matrix, in which each element of one predetermined row is a function of a root of an irreducible polynomial on Galois field GF (2), the syndromes are used to obtain a set of constant word signals (A, B, and C).  Error detection and correction is based on these developed syndrome word and constant word signals, in which if selected syndrome word and constant word signal levels are equal to zero, there is no error word declared; if selected ones of the syndrome word and constant word signal levels are equal to zero and selected other signal levels are not equal to zero, then one error word is declared and error correction is performed by calcula-tion of the syndrome word signals which have been determined to be the equivalent of error pattern signals; and if selected constant word signal levels are not equal to zero, additional constant word signals (D, E) are generated and an error location equation is solved to detect the error locations (i, j) and the two word errors are corrected based on the syndrome/ error pattern relationship.  Up to two word errors in one error correcting block can be detected and corrected and three word errors or four word errors can be corrected if the error locations is known.

Abstract: WATER BOTTLE CRATE            Abstract A crate for a single large generally cylindrical sided bottle has a generally flat bottom and a central tapered filling neck at its top.  Four side walls extend perpend-icularly from a flat bottom wall.  Four intermediate walls are each joined along opposite side edges to respective side edges of adjacent side walls to extend perpendicularly to the bottom wall, parallel to an opposed intermediate wall, at right angles to an adjacent intermediate wall, and at equal angles to adjacent side walls. The side and inter-mediate walls have inner surfaces that taper continuously outwardly from the bottom wall to the top of the crate.  The side and intermediate walls are so related that in any cross sectional view taken parallel to the bottom wall a circle may be drawn about a central axis to intersect each of the intermediate walls and be spaced substantially inwardly from the side walls sufficiently so that in any orientation of the crate about the central axis, when the axis is horizontal, the bottle in the crate will be supported and engaged by the intermediate walls and spaced from the side walls.  This construction holds the bottle safely and securely.

Abstract: ABSTRACT OF THE DISCLOSURE A refrigeration system contains a common compres-sor supplying refrigerant to a plurality of evaporators that are refrigerated and defrosted independently of one another.  Individual refrigeration/defrost controls are pro-vided in solid state form for the respective evaporators, and the individual controls are connected with a master control that prevents all of the evaporators from being defrosted at one time.  The master control includes a digi-tal time clock providing time signals to each of the indivi-dual refrigeration/defrost controls, and each of the indivi-dual controls can initiate a defrost operation for its respective evaporator on either a timed or demand basis.          The master control includes a scanner that interrogates the individual controls in a special manner to initiate defros-ting of the units in order of priority.  The master control permits an individual defrost control for a selected evapo-rator to be tested in a timed mode by substantially increa-sing the speed of the time clock while operation of the remaining defrost controls is inhibited.
