Abstract: ABSTRACT           Apparatus is provided for supporting and guiding a router for the purpose of routing an ornamental design in panels such as cabinet doors and drawer fronts.  The router is attached to the end of a bar extending over the workpiece, the bar being slidable longitudinally in a carriage which in turn is movable on a rail extending at right angles to the bar.  Adjustable stops are provided to limit movement of the bar and carriage so that the router may be guided in a rec-tangular path of movement of predetermined dimensions.  Selec-tively usable templets are provided for changing the path of movement of the router, particularly at the corners of the predetermined rectangular path to vary the design being routed.

Abstract: Abstract of the Disclosure A combination VHF and VHF tuner is provided in which a common station selector shaft may be rotated a number of revolutions to cover the seventy stations in the UHF band.          The common selector shaft is provided with twenty-four detent positions per revolution and in alternate positions of the shaft the twelve VHF stations in the VHF band are received.          As the common selector shaft is rotated through several rev-olutions the VHF stations are repeatedly received but are interspersed with different individual stations in the UHF band.  According1y, no matter what UHF station is being re-ceived, all of the VHF stations are always within one turn of the common selector shaft. In many mixed UHF-VHF recep-tion areas a single turn of the common selector shaft is sufficient to select all of the UHF stations as well as all of the VHF stations which are broadcasting in that area.  Also, any UHF station anywhere in the UHF band is selected with the same ease of selection as the interspersed VHF   stations so that tru  comparability between VHF and UHF reception is achieved.

Abstract: Abstract of the Disclosure An improved package for matches is disclosed, in which the striking surface of the package is protected by a flattenable, generally tubular enclosure.  The enclosure hides the striking surface from view, and prevents a match from being struck unless it is pinched between the striking surface and the interior wall of the enclosure as it is drawn across the striking surface.         The tubular enclosure may include a front cover receiving recess, and normally be in a flattened position, whereby a sliding motion of the front cover towards the tub-ular enclosure while in engagement with the receiving recess expands the tubular enclosure allowing access to the striking surface.

Abstract: ABSTRACT          This invention relates to solar energy collectors, and more especially to evacuated solar energy collectors comprising a housing forming a chamber.  The chamber has a transparent top member and bottom member which are joined together along the tims, thereby providing an airtight seal, the top and bottom members each having a surface convex to the outside whereby the chamber resists the external atmos-pheric pressure while having a relatively large absorber area to collector area ratio.  The bottom member of the collector can have a reflective surface to reflect the solar energy upon the underside of the heat absorbing unit, which is a spiralled tubular element retained within the collector.          Furthermore, a system of solar energy collectors can be constructed so that the top members of the chambers receive solar radiation during the day, and mirrors situated in the interstices between adjacent collectors direct solar energy to transparent lower surfaces of the collectors, the low profile of each chamber facilitating the architectural integration of the collectors in close-packed arrays.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in a gas outlet device which includes a valve housing an inlet section to the valve housing, and a connector tube that is adapted to be inserted into and interengaged with the gas in-let section so as to cause the flow of gas through the valve housing, the inlet section and the outlet section.  The improvement comprises (1) the perimeter of the opening containing diametrically opposed slots, (2) two diametrically opposed elongated ridges extending along the exterior surface of the connector tube, the elongated ridges being adapted to pass through the slots in the inlet section, (3) a pair of spaced apart and parallel locking wires extending across the opening of the inlet section, (4) two spaced apart wire engaging members located on the exterior of the connec-tor tube, each of the wire engaging members including a first portion that is adapted to spread the locking wires outwardly with respect to each other and a second transverse slot portion that allows the locking wires to re-turn to an approximately parallel relationship, and (5) a disengager mem-ber associated with the connector tube which will when activated by pulling the connector tube, dislodge the locking wires from the transverse slot portion.  A gas outlet device and a connector tube are thus provided that can be engaged and disengaged by simply pushing and pulling the connector tube.  In other words, by pushing the connector tube into the inlet section the locking wires will engage with the transverse slot portions to thereby hold the connector tube and inlet section together and by pulling the con-nector tube away from the inlet section the disengager member will dislodge the locking wires from the transverse slot portion.  This thereby elimin-ates the necessity for rotating the connector tube in order to engage it with the gas outlet device.

Abstract: ABSTRACT OF THE DISCLOSURE A heat transfer tube for the water-spray panel evaporator for the gasification of liquefied natural gases which includes a tube having a pair of planar members each projecting outwardly from its peripheral surface, radially with respect to its longitudinal axis and extending longitudinally along such axis, and an internal fin disposed within the tube and having at least three fin members each projecting radially with respect to the longitudinal axis to provide a helicoidal formation extending along and about the longitudinal axis, the helix of the heli-coidal formation contacting the internal wall of the tube in a pressure-fitting relationship.  These heat transfer tubes can be assembled to provide a panel evaporator.  The method for fabricating such heat transfer tubes and assemblies is character-ized in that the above pressure-fitting relationship is established by drawing the tuba alone to reduce its internal diameter until the helix of the helicoid is abutted against the internal wall of the tube.

Abstract: ABSTRACT     In a wheel mounting a hub rotates within a steering knuckle or other carrier on a double row tapered roller bearing of the indirect configuration.  This bearing includes a double cup that is fitted into the carrier, a pair of cones that are pressed over the hub, tapered rollers arranged in two rows be-tween the opposed raceways of the cup and cones, and a cage for each row of rollers.  The retaining ribs on the cones have beveled surfaces so that as the hub is withdrawn from the steer-ing knuckle, in which case one of the cones will be carried along with the hub, the beveled surface on the cone that moves with the hub will deflect the small ends of its rollers outwardly to enable the cone to pass through the rollers and free itself from the cup without shearing off snap rings or similar devices that secure the cup in place.
