Abstract: SCRAPER MECHANISM FOR DISK GANG HARROWS     ABSTRACT OF THE DISCLOSURE         A scraper mechanism for the disk gangs of disk harrows and embodying a series of flexible scraper arms, one for each disk, which depend from a common scraper support and carry scraper blades at their lower ends.  The upper ends of the scraper arms are turned laterally and provide short attachment sections of wide angle concavo-convex configuration.  A clamping bolt extends through the apex of each section and the support and, upon tightening thereof progressively flattens the section against the support and thus swings the depending portion of the scraper arm in the direction of the respective disk for regulating the pressure of the scraper blade against the disk.  Means are provided for shifting the position of the common scraper support so that collective adjustment of the various scraper blades may be effected.  Where folding wing type disk harrows are concerned, a modified scraper arm construction is employed to avoid frame interference in the vicinity of the hinge connection for the wing gang section, such construction embodying a wide angle concavo-convex attachment section wherein the convex side thereof abuts against a flat surface which is downwardly offset from the scraper support.  A pair of clamping bolts project through the concavo-convex section on opposite sides thereof and, when tightened, flattens the section against such offset surface for scraper blade pressure regulating purposes.  Where a given disk gang utilizes a furrow filler disk at its outer end, a second modified form of scraper arm construction is employed wherein an over-hanging extension bracket on the end of the scraper support is provided.

Abstract: ABSTRACT OF THE DISCLOSURE           A toy balancing scale used to teach children the proper relationship between the number of objects and/or the value of numbers, has a base having an upstanding support and pivoted on the support is a horizontal balance bar.  The balance bar is pivoted utilizing a fulcrum and a knife edge resting on the fulcrum.  The balance bar is symmetrical about the knife's edge and as such by itself will remain in a hor-izontal position under the influence of gravity.  At each end of the balance bar is a small peg on which objects can be attached.           On the backside of the balance bar is a housing having essentially a "spade-like" shape.  The distance within the housing from the top of the spade to the bottom of the stem of the spade is longer than the distance from the top of the spade to the side projections.  Mounted on the support is a sliding member having a peg which projects normal to the surface of the sliding member.  The member slides vertically in the support and the peg fits in the spade-like housing. When the peg is at the top of the housing the balance bar is held in a locked position about the peg.  As the sliding member is moved down and if the balance bar is in balance, the peg will go straight down into the stem of the housing. If the arm is not in balance when the peg is moved from the top of the housing the arm will tilt and the peg will come to rest within the left or right side projection of the spade-like housing.  Since the housing has a longer dimension from the point of the housing to the bottom of the stem than from the point of the housing to one of the side projections, the peg and the sliding member will consequently travel a greater distance when the arm is in balance than when it is not.  A clanger and bell mechanism is activated by the sliding member when the member is free to travel this greater dis-tance.  If, however, i.e., the balance arm is unbalanced, the member will only be free to travel a limited amount and the clanger and bell mechanism will not be activated.  This allows a child to determine whether or not the number of objects or the numbers on one side of the balance bar are equal to the number on the other side of the balance bar.

Abstract: SIGNATURE VERIFICATION METHOD AND APPARATUS UTILIZING    BOTH ACCELERATION AND PRESSURE CHARACTERISTICS                        Abstract of the Invention Method and apparatus are disclosed for verifying a sample signature based on comparison of the dynamics of a reference and a sample signature.  More particularly, second derivative values of pen displacements (i.e. acceleration) and continuous pressure pattern signals are periodically sampled for both a reference and sample signature and a comparison of these second derivative values and pressure patterns is made.  To effect the comparisons the two groups (reference and sample) of both second derivative and pressure pattern signals are segmented and corresponding segments are individually correlated. Successive comparisons of the same segment pairs are performed utilizing successive shifting of the phases between the two segments being correlated to find regions of highest possible correlation.  A running account of the maximum cross correlation values for all of the segment pairs of the two signatures are kept.  Finally, these maximum values obtained for each segment pair comparison are combined and this resultant correlation value is utilized as a verification indicator.

Abstract: ABSTRACT OF THE DISCLOSURE:           A synthetic plastics or rubber sheet structure having a surface applied pattern in one or more colours extending thereinto, is produced by applying to the surface of the sheet structure at least one colouring agent capable of undergoing migration through the synthetic plastics material and effecting migration of the colouring agent through the sheet structure in the presence of at least one cross-linkable component until the colouring agent has penetrated to a predetermined depth and cross-linking of the cross-linkable component is initiated thereby to stop further migration of the colouring agent on cross-linking of the cross-linkable component.  The invention makes it possible to produce a sheet structure having a visible pattern in accordance with the pattern in which the colouring agents are applied, which may be varied as desired on the surface of the sheet structure.  In this way, a design can be produced in the sheet structure with a variable thickness including the possibility that penetration of the pattern right through the sheet structure occurs.  The effective life of a product coloured by the process of this invention, which product is for example exposed to heavy wear, is now solely dependent on the effective life of the sheet structure itself and is no longer dependent on the resistance to wear or abrasion of a printed impression or of a transparent covering layer which is applied thereto.

Abstract: ABSTRACT OF THE DISCLOSURE            A wiring distribution system for fill-on-slab or fill-on-grade floor constructions, including an uninterrupted main unit providing main passageways and at least one laterally extending feeder unit providing feeder passageways supported on a substructure (-slab or -grade).  A housing having a removable cover encloses a full-width segment of the main unit and an end segment of the feeder unit.  A covering layer of concrete (fill-) surrounds the housing.  A partition divides the interior of the enclosure into two compartments, a first communicating with one feeder passageway and a second communicating with the other feeder passageways.  The main unit presents at least one common lengthwise trough ex-tending through and beyond the opposite sides of the enclo-sure.  First and second capping means enclose those portions of the common lengthwise trough on opposite sides of the enclosure to provide substantially unobstructed additional main passageways communicating with the second compartment. Isolator means within the housing isolates the first com-partment from the common lengthwise trough.  The arrangement is such that high voltage wiring extending through a desig-nated main passageway may be fed through the first compart-ment to a corresponding feeder passageway whereas low voltage wiring, such as telephone and signal wiring, ex-tending through others of the main passageways may be fed through the second compartment to corresponding feeder passageways.

Abstract: ABSTRACT OF THE DISCLOSURE         A device is disclosed for amplifying electromagnetic waves propagating along a meander line slow wave structure by means of magnetic cylindrical domains or bubbles which are propagating at substantially the same velocity as the RF wave in an adjacent platelet of orthoferrite having associated with it a propagation arrangement of the conventional type which is adapted to move the domains from one end of the platelet to the other.          Since the magnetic bubbles are magnetic dipoles that produce magnetic surface charges, a portion of their energy is transferred to the propagating RF wave, resulting in amplification of the RF wave.
