Abstract: METHOD AND APPARATUS FOR MAKING MULTI-LAYER SPIRAL PIPE                     ABSTRACT OF THE DISCLOSURE    An apparatus and method for continuously forming multi-layer metal pipe from at least two elongated sheets of metal.  One sheet is impressed with longitudinal corrugations in a rolling device and the second sheet, being uncorrugated, is then positioned con-tiguously upon the first, forming a multi-layer sheet.  One or more removable modules is mounted in the rolling device to accu-rately align and guide the second sheet into position upon the first.  Complementary portions of a single corrugation are then formed in the marginal edges of the multi-layer sheet and the sheet is spiralled into adjacent, helical convolutions in a pipe forming device, with the uncorrugated sheet forming the pipe interior.          The adjacent convolutions are joined in a helical seam in the single corrugation by a seaming device located in the pipe forming device.          In the primary embodiment of the invention, the seam is formed as a double lock seam along a neutral axis of the single corrugation.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention provides metal-thermoplastic-metal laminates and a process for preparing same, which have in combination critical service properties of high heat distor-tion temperature, low coefficient of linear thermal expansion, low inelastic ratio and lightness in weight.  The core layer is selected from the group consisting of partly crystalline polymers and polyesters having a crystalline melting point greater than 130°C. and has a minimum thickness of 0.0483 cm. Each metal layer has a melting point greater than the cry-stalline melting point of the core and a minimum thickness of 0.00127 cm.  The thickness ratio of the sum of the metal layers to the core layer thickness is described by the region of numerical overlap of TR(YSm/TSc) wherein TR is the thickness ratio of the sum of the metal layer thicknesses to the thermoplastic core layer thickness; YSm is the thickness-weight-average tensile yield strength of the two metal layers at an offset of 5% elongation; and TSc is the tensile strength of the thermoplastic core layer.  This is determined from the areas defined by the relationships of TR(YSm/TSc) to the inelastic ratio of the laminate as measured in flexure at 5% strain in the outer metal layers at the point of maximum deflection (TR?); the coefficient of linear thermal expansion of the laminate (CLTE?); and a normalized heat distortion temperature variable (HDT? - HDTC)/(Tm  - HDTc).  The lower boundary of these areas is defined by the equation of a straight line y = mx + b in which y is the y-axis parameters of IR?, CLTE?, and (HDT? - HDTc)/(Tmc - HDTc), x is the x-axis parameter of TR(YSm/TSc), m is the slope of the straight line, and b is the intercept on the y-axis.  The laminates of this invention may be used in construction applications such as outer and inner building panels, appliance panels, and transportation vehicle body panels for example, automobiles, boats, airplanes and the like.

Abstract: 38                    47,719I2 ABSTRACT OF THE DISCLOSURE High  frequency  electrodeless  (HFE)  lamp  has high-permeability  core  such  as  ferrite  positioned  in energy  transferring  relationship  with  respect  to  the phosphor-coated lamp envelope.  The core forms a part of a tuned  circuit  output  for  a  radio-frequency  energizing source and during lamp operation, the resulting electro-magnetic fields generated within the lamp envelope create a discharge which in turn generates radiations to excite the phosphor to produce visible light.  The core is spec-ially designed to include narrow gap means of low-permea-bility substance and this gap improves lamp performance by providing  the  dual  function of  stabilizing  the  output frequency of the tuned circuit to compensate for varia-tions in permeability of the core and, in addition, the resulting increased Q of the tuned circuit substantially suppresses harmonics of the resonant frequency which are undesirable  in  such  a lamp.   There is also provided a method for assembling such a lamp as well as the finished lamp wherein the phosphor-coated envelope can be processed and sealed, and thereafter the core is assembled therewith so that the core is not subject to the temperature ex-tremes required for proper envelope processing.

Abstract: REFLECTOR SYSTEM HAVING SHARP       LIGHT CUTOFF CHARACTERISTICS           ABSTRACT OF THE DISCLOSURE      A light fixture comprising parabolic reflector segments therein, the lamp being located at the focal point of the segments.  One segment has an arc preferably more shallow than the other segment.  The window opening is angled preferably at an angle of 60 degrees to the elongate axis of the parabolic segments to provide sharper light cutoff or less spill light from one reflector segment than from the other.  A shield positioned parallel to the elongate axis and on the side of the axis within the reflector segment where the cutoff characteristics are the greatest, permits primary reflected light from the lamp, while preventing direct light from the lamp to pass above the shield.  The specular underside of the shield enhances light reflection therefrom while the darkened top shield surface blocks secondary reflection above the cutoff angle.
