Abstract: A SELF-DEPLOYABLE AIR SPOILER ASSEMBLY               ABSTRACT OF THE DISCLOSURE      A self-deployable front air spoiler assembly mounted beneath a vehicle underbody, the air spoiler assembly com-prising a laterally extending airfoil which in non-deployed condition is situated in a semi-concealed position.  The airfoil is supported at each side of the longitudinal center of the vehicle on swingable links, each link being pivotally coupled at one end to the airfoil and at the other end to the vehicle underbody.  The pivot axes of the links are sub-stantially parallel to the airfoil.  Biasing means interposed between the air spoiler assembly and the vehicle underbody normally biases the airfoil toward its deployed condition.          As the air pressure against the front face of the airfoil in-creases as the speed of the vehicle is increased, the airfoil swings downwardly increasing the frontal area impacted by the airstream and restricting the flow of air beneath the vehicle underbody.

Abstract: Abstract A merchandise display fixture of the type wherein a horizontal bar is supported between two or more spaced brackets extending forwardly from a supporting column which has its outer end bent to a generally U-shaped contour.  The two leg portions of the U each have a vertical slot therein, these being directly opposite each other and are of a shape and dimension designed to snugly receive the horizontal bar to be supported.  The base portion of the U-shaped end of the bracket has a cam element thereon arranged to bear against the outer face of the horizontal bar as it is forced down-wardly into the opposed vertical slots and spring the edges of the slot into tight binding contact with the horizontal bar, holding it against longitudinal movement and requiring force to lift it from the slots.

Abstract: 26.3.79                      1                 PHD.78-033 "ABSTRACT":         "Device for determining the radiation absorption distribution in a plane of examination".     In computer tomography apparatus the radiation intensity of the radiation source remains constant during a measuring operation. This means that in those positions in which the absorption of the radiation through the patient is particularly weak, the patient gets an un-necessarily large dose without any useful effect, as only a distinct number of X-ray quanta is required for a given measuring accuracy. It is an object of the invention to measure the radiation absorption distribution at a reduced dose but without the measuring accuracy being affected. The radiation intensity of the radiation source in a measuring position is made dependent on the mean measuring error of the adjacent measuring position; the mean measuring error does then indeed not remain constant but it  fluctuates less than when a constant intensity of the radiation source is used.

Abstract: INSOLUBILIZED DEOXYRIBONUCLEIC ACID  (DNA) ABSTRACT OF THE DISCLOSURE       A method of detecting antibodies to native deoxyribonucleic acid (n-DNA), anti-nuclear antibodies, antibodies to non-histone containing protein, rheumatoid factors, antibodies to thyroglobulin, and an immuno-fluorescent assay for such detection is described.  The method comprises incubating an insoluble conjugate of methylated bovine serum albumin (mBSA)-native deoxyribonucleic acid (n-DNA) or other substrates with serum from patients with systemic lupus erythematosus (SLE) or other autoimmune diseases for a sufficient length of time, washing the pre-cipitate or flocculate, separating and discarding therefrom the super-natant fluid, adding a fluorescein labeled anti-immunoglobulin antibody to the washed flocculate and incubating the labeled mixture for a suf-ficient length of time, washing the incubated flocculate and separating therefrom the supernatant fluid, suspending the pellet in a liquid medium to determine the fluorescence of the flocculate, which is proportional to the concentration of antibodies to deoxyribonucleic acid and others in serum specimen.  The insoluble conjugate of methylated bovine serum albumin (mBSA)-native deoxyribonucleic acid (n-DNA) retains the double-stranded form of native deoxyribonucleic acid (n-DNA).

Abstract: CONTAINER AND LID OF MOLDED PLASTIC MATERIAL                     Abstract The fastener structure connects two peripherally interengaging, molded plastic members, the fastener structure consisting of two identical complementary, continuous, endless peripheral series of fastener elements.  This structure as shown secures a lid to a can, the series of elements on the lid interengaging with the series on the wall of the can, the spaces between elements in each series being substantially similar to the elements, with each element narrower at its base than at the top so that the space between the bases of adjoining elements is wider to receive a com-plementary element.  The two series are interengaged by pressing the two series together as the lid is inserted in the end of the can, the flexibility and resilience of the material allowing the two endless series to interengage.     One of the wall structures is inclined so that the members are in wedging contact to form sealing surfaces.      Each series of elements is fixed on the side of a wall, so that when the two walls are moved in the direc-tion of their contacting surfaces, the two series of elements interengage to hold the two wall structures in contact.  To hold the wall structures in tight, seal-ing contact, the elements are inclined transversely to the direction of inter engagement, so that the contact-ing surfaces are pressed together by engagement of the fastener elements.

Abstract: ABSTRACT OF THE DISCLOSURE         A file binding system according to the present invention comprises a pair of elongated rigid support members for supporting a file along its edge and securing members for securing the support members in position.          The support members are fully separable from one another and from the file edge with the securing members being independent of the support members other than in the securing position, thereby adapting the arrangement for use with essentially any file size.  Furthermore, each of the securing members includes securing portions for securing the support members from their outer sides along the file edge.  This latter feature not only facilitates binding adjustment but also provides an extremely effective clamping of the file edge between the support members.
