Granted: 1980-09-30
Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to method and apparatus for manufacturing a sheet of flexible plastic material capable of being manually altered to selected width.  A plurality of parallel, laterally spaced longitudinal slits, preferably  penetrating one-twelfth to one-half the thickness of the material, are formed parallel to one edge of the sheet, defining a plurality of marginal side segments, which may be manually removed, leaving a generally straight and even edge, thereby producing a usable sheet of reduced width.  Preferably, the slits are rendered inconspicuous by being made no more than 0.025 mm in width.         Apparatus to carry out the method comprises means for drawing plastic sheet material from a supply roll, and either drawing it between a support member  and a multiple blade cutter biased toward the support member, or alternatively, disposing the sheet incrementally on a suitable support member, for slitting by a reciprocally moving multiple-blade cutter.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method for the production of polyether polyol compositions is disclosed wherein a polyhydric initiator is oxyalkylated with alkylene epoxides at lower temperatures in the presence of an aqueous ammonia solution. The polyether polyol compositions produced have desirable hydroxyl numbers and low viscosities and are particularly useful in the production of excellent rigid polyurethane foams.  In addition to catalyzing the reaction, the nitrogen containing moiety itself undergoes oxyalkylation during the process such that the polyether polyol composi-tions produced contain, admixed therewith, various alkoxyalkanol amines.  The alkoxyalkanol amines having reactive hydroxyl groups and acting as a mild catalyst for the polyol isocyanate reaction need not be removed from the polyether polyol composition. In addition, the alkoxyalkanol amines increase the blending compatability of the polyether polyol compositions.                             -I-

Abstract: ABSTRACT OF THE DISCLOSURE            A mechanism is provided for soldering the leads of electronic components, such as integrated circuit elements, to corresponding conductors on a printed circuit board.  The mecha-nism utilizes the known lap soldering reflow process by which the leads of the electronic component and the printed circuit conductors are solder coated, and a heated soldering tip holds each component lend and the corresponding printed circuit conduc-tor in contact with one another while melting the solder on the lead and on the conductor.  The soldering tip continues to hold the lead and conductor in contact with one another after the heat in the tip has been terminated and until the solder soli-difies.  The soldering tip is then removed leaving a soldered joint. The mechanism of the invention, in the embodiment to be described, includes two multi-tip soldering heads which can be adjusted to any desired longitudinal separation and to any desired lateral position with respect to the printed circuit board so as to align the soldering tips with the leads of a wide variety of electronic components on the board of varying sizes and shapes. The mechanism of the invention also has the ability to activate and set any combination of soldering tips to the soldering posi-tion so as to align selected soldering tips, for example, with integrated circuit component leads of different numbers of vary-ing spacings.  Also, the soldering tips of the mechanism of the invention each undergoes a stress reducing cycle during the solder-ing operation to reduce subsequent solder joint failure.
