Abstract: LATERALLY CURVED DECORATIVE TRIM STRIP ASSEMBLY AND METHOD OF MAKING SAME.               ABSTRACT OF THE DISCLOSURE   A  decorative trim strip  assembly  for vehicles  is provided,  having  a  laterally  curved portion  formed therein.  The  assembly  comprises  a  metallic  backing plate and a polymeric  resinous strip element  (usually polyvinyl  chloride)   bonded  to   it.   At  least  one longitudinal slit  is formed  in the polymeric  resinous material  so as  to  form  longitudinal  strip  portions therein, in the area of the curved portion, and  each of the  longitudinal  strip  portions  is  stressed  to  an extent less  than  that  which  would  cause undesirable deformation.  In forming the decorative  strip, the slit polymeric  material is placed into a jig, with the  ends of  the  slit  portions  thereof  extending  to  varying amounts beyond  the curve,  the jigged  element is  then bonded to  the backing  plate (usually by heat bonding), and  any excess amount  of polymeric material  extending beyond the  curved portion which is not required is then trimmed off.

Abstract: Abstract of the Disclosure Subtractive filters are moved into and outfrom the light path between a lamp and a supported color transparency in a color enlarger to provide three separate exposures for the colors red, green and blue.  Operator setable means provides an exposure time for each color exposure based on the color density of a standardized transparency, balance means adjusts the exposure time for each color exposure to compoensate for differences in color density between the standardized transparency and a transparency from which a color print is to be made.  The balance means includes a light intensity sensor means between the transparency and the lens.  Magenta and yellow filters are moved together into the light path to produce the color red.  Yellow and cyan filters produce the color green.  Cyan and magenta filters produce the color blue.          At the end of the red exposure the cyan filter is moved back into the white light path before the yellow filter is withdrawn.  At the end of the green exposure the yellow and cyan filters are delayed in the white light path until all white light has disappeared.  A portion of the magenta filter is moved into the light path during the green exposure and a portion of the yellow filter is moved into the light path during the green exposure.  This shutters off some of the light, permitting an increase in the exposure time for the colors green and blue.

Abstract: FLUID FLOW CONTROL DEVICE     ABSTRACT OF THE DISCLOSURE           A fluid flow control device comprises first, second, and third fluid conduits.  The first and second conduits are adapted to communicate with separate sources of pressurized fluid.  The third conduit includes an inlet portion in direct flow communication with the first conduit and an outlet portion communicating with the atmosphere.  A flexible wall forms an interface between portions of the second and third conduits.  In response to fluid pressure fluctuations in the second conduit, the flexible wall simultaneously meters the flow communication through both the inlet and outlet portions of the third conduit.  The fluid pressure in the first conduit is thereby elevated until substantial equilibrium with the fluid pressure in the second conduit occurs.

Abstract: A b s t r a c t A dragee-making drum (10), whose axis of rotation (A) is at least approximately horizontal, has an at least approximately cylindrical shell (12) and two at least approximately frustum-shaped end wall por-tions (14) adjoining either side of the shell. These end wall portions (14) extend into the space enclosed by the shell (12) and terminate in annular zones (16) whose axial distance (C) from one another is consider-ably smaller than the width (B) of the shell (12).            It is thereby achieved that the dragee-making material is spread between the frustum-shaped end wall portions (14). This gives rise to frictional forces which, in addition to the frictional forces that are caused by gravity and are the only forces having effect in known dragee-making drums, tend to entrain the dragee-making material in an upward direction as the drum rotates. Consequently, at a given speed of rotation of the dragee-making drum, the dragee-making material ascends further and above all more uniformly, in order to then finally spill down again.
