Title: Method and apparatus for forming expanded  foam articles
Inventor: SMITH STUART B
IPC: C08J3/20
Filed: 1980-04-08
Granted: 1982-09-07
Abstract: ABSTRACT A method and apparatus for forming foam articles is described. Thermoplastic resin beads containing a blowing agent are continually agitated in a heated pre-expansion chamber to a temperature near the fusion point of the beads and above the boiling point of the blowing agent at substantially atmospheric pressure. The beads soften and expand substantially in volume. A dry gaseous medium may be swept over the beads to remove moisture and any blowing agent which has escaped. Thereafter, the chamber is evacuated. Evacuation continues until a predetermined amount of blowing agent is removed from the beads. As a preferred embodiment of the invention, steam may be injected into the chamber prior to evacua-tion. This serves to further expand the beads, and facilitates the removal of the blowing agent. This embodiment also provides a means of manufacturing particularly stable low-density foam. The expanded beads, after they are restored to atmospheric pressure, are discharged to a storage facility and maintained at an elevated temperature for immediate use in a molding apparatus. The expand-ed hot beads may be fed directly by air injection conveyors to mold cavities and molded into the desired articles.

Abstract: ABSTRACT:     In a method for manufacturing an integrated circuit, a masking layer is used having a bottom layer and a second layer on top of the bottom layer and of a different material.  In this masking layer, two mask portions are defined, mutually separated by an aper-ture.  The first mask portion covers the region of the emitter and a part of the extrinsic base portion besides the emitter.  Via said aperture, a portion of the extrinsic base is provided, after which the bottom layer of the first mask portion is etched to remove an edge portion of the bottom layer by lateral etching. Then, a second part of the extrinsic base portion is provided, after which an oxide layer is formed upon the uncovered parts of the surface.  The remaining part of the first mask portion is removed then, and the emitter and the intrinsic base portion can be pro-vided then.  Simultaneously the bottom layer of the second mask portion  may be etched in order to define base and collector contact windows.

Abstract: T I T L E                     METHOD OF PRODUCING OPTICAL                      FIBER ACCESS COUPLER                          I N V E N T O R S                       BRIAN S. KAWASAKI                       KENNETH O. HILL                       DERWYN C. JOHNSON     ABSTRACT OF DISCLOSURE                  The low loss access coupler includes two multi-mode optic fibers, each having a biconical taper section.  The biconical taper sections of the fibers are fused together to provide optical coupling between the fibers.  The fused fibers may also be twisted around one another to enhance mode mixing.          The access couplers may be produced by fusing two fibers together along a small length, then heating the fused  length and pulling the fibers to form the  biconical tapers; or by twisting a portion of each of the fibers around-one another, applying a tensile force to the twisted portions of the fibers and heating a region of the twisted fibers to soften and fuse a predetermined length of twisted fibers. If the fibers already have biconical taper sections, the access coupler may be produced by twisting the fibers together along their taper sections and heating a region of the taper sections to fuse them together.

Granted: 1982-12-07
Abstract: ABSTRACT     The adjustable wrench is of the open-ended wrench type in-cluding a manually graspable handle and a nut-seizing jaw con-nected to the handle.  The jaw includes an upper jaw and a lower jaw spaced a fixed distance from each other to define an open-ing for receiving a nut, and a slot communicating with the o-pening and extending through the jaw.  A plurality of equal size shims are longitudinally slidable through the slot from a location outside of the opening to a location inside of the opening to provide a variable dimension for the nut-receiving opening.  The handle includes a shelf portion adjacent the jaws for supporting the plurality of equal size  shims and the plu-rality of equal size shims comprises interlock means for pre-venting any shim from being located inside of the opening un-less there is supportive contact with the jaw.  The interlock means comprises equal size lugs carried by the shims, and each of the shims defines a groove for receiving the lug of an un-derlying shim, the plurality of equal size shims being posi-tioned for sequentially varying the nut-receiving opening di-mension by longitudinally moving the shims into the opening with the shims that are moved into the opening being in suppor-tive contact with the jaw.  An abutment means carried by the top shim adjacent to and spaced from the lug on said top shim to prevent the shims from sliding further than a predetermined distance and to provide a space between the lug on the top shim and the jaw when the shims are slid inside the opening is also provided.

Abstract: ABSTRACT:      An aluminium sheet product is formed from an alloy containing Fe 0.6 - 1.0%, Si 0.5 - 0.9% and Cu 0.3 - 0.5% and incl ies Ti and B in conventional grain refining amount.  Mn is permissible in amount up to 0.2 - 0.3% but is preferably held below 0.1%.  The Mg impurity content is preferably held at a very low value so as to avoid difficulties with adhesion of lacquer.         The principle use of the sheet product is for the production of bottle closures and for that purpose it is preferably produced in a thickness of 0.15 - 0.25 mm. and in a quality having a low percentage earing and fine grain size.  For this purpose the sheet is subjected to a temper cold rolling reduction of 30 - 60% after the last inter-annealing treatment.  No homogenisation treatment is required before hot reduction of the cast ingot and no precipitation heat-treatment is applied to the hot-rolled product before cold rolling.

Abstract: PARALLEL RESONANT INDUCTION COOKING SURFACE UNIT                  ABSTRACT OF THE DISCLOSURE     A parallel resonant induction cooking surface unit comprises a voltage fed inverter which drives a load circuit, comprised of a main induction drive coil, a tuning capacitor coupled in parallel with the main induction drive coil, and an inductor coupled in series with the main induction drive coil, with a square wave voltage causing the main induction drive coil to generate a time variant magnetic field, resulting in eddy currents being induced in the surface of a metallic, food-containing utensil positioned adjacent to the main induction drive coil, and hence causing utensil heating. By tuning the load circuit to resonance at or near the square wave frequency, reactive currents therein are minimized, resulting in improved power factor. Moreover, resultant main induction drive coil voltage and current are nearly sinusoidal, thereby achieving reduced electro-magnetic interference radiation at frequencies greater than the square wave frequency.

Abstract: ABSTRACT OF THE DISCLOSURE:          THe invention relates to a process of Producing an S03-containing Gas for Use in the Purification of an Exhaust Gas in an Electrostatic Precipitator.  The process serves to produce an S03-containing gas by a combustion of sulfur in a furnace with combustion air fed by a blower.  The resulting combustion gas has a high S02 content, which is catalytically oxidized to S03 in the presence of oxygen in a converter.  The S03-containing gas is admixed to a water vapor-containing exhaust gas before the latter is purified in an electrostatic precipitator.  The furnace is fed with sulfur in liquid form by a proportioning feeder and with the combustion air through an air heater.  A control of the combustion condi-tions in the furnace and an adjustment of the optimum temperature for the reaction in the converter can be effected by a control of the sulfur rate, the rate and/or temperature of the com-bustion air or the rate of the cooling air admixed to the combustion gas.  The temperature may be measured at the inlet or outlet of the converter.
