Abstract: A miniature golf apparatus has a variable putting surface with a hole and sunken lights disposed adjacent each end. Consoles at each end provide for random selection of the putting surface contour and the illumination of lights to locate the commencement of putts to the hole at the opposite end of the device. To vary the putting surface, additional alternate manual selection is also provided. A pair of rotatably driven beams have a plurality of cross bars of different lengths resiliently and pivotally attached to extensions of the beams. The putting surface is disposed on clip members carried by the bars. Independent rotation of the beams about their longitudinal axes provide lengthwise undulations and widthwise slant of the putting surface. Crank arms and motors carried by some of the bars flex the bars to give a curvature to the putting surface.

Abstract: A method and apparatus for manufacturing business forms from rolls of paper webs. The webs are divided into at least two groups. The webs of a first group are individually processed as by printing or the like and guided into superimposed relationship. A line of holes is punched simultaneously through all of the webs of the first group, and the webs of such first group are advanced as a unit through the processing operation by a pinned belt engaging such holes. The webs of the second group are individually processed separately from the first group as by printing or the like, and are guided into superimposed relationship beneath the superimposed webs of the first group. A line of holes is punched simultaneously through all of the webs of the second group with some of the holes being in center registration with the line of holes in the first group, and the webs of both groups are advanced as a unit by a pinned belt engaging the line of holes in the webs of both groups.

Abstract: Finned tubing for use in heat exchangers has tapered helical fins with serrations disposed between connecting webs. The opposed edges of the serrations, interior of the periphery, taper to a relatively sharp edge. Shark-fin like protuberances project outwardly adjacent one leg of each serration with each protuberance having a flange thereon. In one modification, the serrations on adjacent fins are spirally aligned. One method and apparatus of producing the finned tubing subjects a tensioned strip to graduated compression to curl the strip onto a tube to form fins, while simultaneously relieving a portion of the compression at spaced points along the periphery of the strip, resulting in a tearing of the strip to provide the serrations, and the adjacent protuberances. The protuberances are then compressed by rollers to form the flanges. An apparatus for carrying out the method includes a pair of rotary members to taper and curl the strip, with one of the rotary members having a series of recesses.
