Abstract: METHOD OF INDUCTION HEAT TREATING, QUENCHING AND TEMPERING, OF STRUCTURAL MEMBERS                   Abstract of the Disclosure This invention relates to a method of induction heat treating and restraint quenching structural members, particularly those of low carbon alloy steel  (lean content), to a uniform martensitic structure, such that distortion of the member due to rapid quenching is controlled.  The members would generally be of a channel shape and they would be heated by induction pre-heating in several stages to austenitizing temperature, namely 1450° to 1750°F, and then liquid quenching the channel member and restraining the channel on both its web and its flanges to below 900°F to minimize distortion and then tempering the channel at a temperature of 750° to 1000°F and again restraining it while cooling to avoid distortion.  These would generally be truck side rails and they would be low carbon alloy steels (lean content), approximate carbon content of .22-30%, manganese 1.00 to 1.35%, sulfur .05% max., phosphorus .04% max., with minimum physical properties after heat treating of yield strength 110,000 psi and tensile strength 125,000 psi.  The induction preheating is done at about 10,000 cycles.  The inductors would be either hairpin coils, oval coils or possibly pancake coils.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for processing sheet material in a bath of liquid comprising a pair of drivable endless bands between which the sheet material is held to carry it through the liquid bath in a container.   The bands are permeable to allow access of the liquid to the sheet and follow a path between stationary scraper bars which guide the bands to follow a slightly sinuous path, thereby ensuring contact between the bands, and which press the liquid through the permeable bands.  Conveniently the bands, which are of woven material and driven by splined rollers, follow a generally U-shaped path within the container.  For processing X-ray films in piece or strip form a series of processing units are used side by side with a common drive system.

Abstract: GLASSES AND GLASS-CERAMICS SUITABLE      FOR INDUCTION HEATING                Abstract of the Disclosure The instant invention relates to the production of glass and glass-ceramic compositions containing a ferri-magnetic crystal phase throughout which respond thermally to fields generated by induction coils. Magnetite (Fe304) is the preferred ferrimagnetic crystal phase because of its high permeability and low resistivity (-10-4 ohm-cm) at room temperature as well as the relative low cost of iron when compared with other ferrimagnetic species.  Two general composition areas are of interest:  Na2O and/or K2O-FeO-B2O3-SiO2 and Li2O-A12O3-B2O3-SiO2.  Where the coefficient of thermal expansion is sufficiently low to import good thermal shock resistance, the compositions can be considered for top-of-stove cooking vessels.

Abstract: CONTIGUOUS DISK BUBBLE STORAGE                      Abstract A bubble storage system using contiguous propagation elements is described using magnetically soft drive layers for movement of the bubble domains in a bubble domain film, in response to the reorientation of a magnetic drive field in the plane of the drive layers. In contrast with prior art contiguous element propa-gation structures, charged walls are not employed for movement of bubble domains.  Instead, magnetic poles along the drive layers are used to move the domains. Two drive layers are used, each of which is comprised of a magnetically soft material, such as permalloy. The drive layers are located at different heights with respect to the layer in which the magnetic bubble domains exist, the bottom drive layer being comprised of contiguous propagation elements defining a generally undulating edge along which the magnetic bubble domains move.  This layer can be comprised of permalloy con-tiguous disks, diamonds, etc.  The top layer is comprised of magnetically soft elements located over the cusp regions formed along the undulating edges of the underlying drive layer.  For propagation around the disks or diamonds, the bottom drive layer is predominant in determining bubble motion.  However, in the area of the cusp regions along the undulating edge defined by the bottom drive layer, the magnetic poles produced by the top drive layer are predominant.  These elements in the top drive layer produce potential wells at those locations corresponding to cusps along the undulating edge defined by the contiguous propagation elements in the bottom drive layer, and therefore control bubble motion in the cusp regions. This eliminates a serious problem to satisfactory bubble motion along contiguous propagation element devices.  A single level masking fabrication process is described where the top and bottom drive layers can be fabricated through the same mask, and a total chip design is shown which provides all functions required in a complete storage chip.

Abstract: Abstract of the Disclosure A process for rejuvenating and recycling used asphalt and a machine including a pugmill mixing chamber for mixing crushed as-phalt supplied thereto and for mixing water, calcium oxide and as-phalt oil therewith is disclosed.  The water and calcium oxide mix-ture react and chemically combine to form a calcium hydroxide filler material to thus fill the voids and gaps in the rejuvenated asphalt that would otherwise exist.  The reaction, being exothermic, increase the temperature of the resultant asphalt based mixture to a level suitable for spreading of the rejuvenated material on a prepared sur-face.  The asphalt oil is preferably preheated using a heat exchanger coil connected to a diesel engine radiator, which coil is immersed in an asphalt oil storage tank carried on the machine so that the vis-cosity of the oil may be reduced to a reasonable value suitable for pumping to the mixing chamber and spraying on the materials contain-ed therein.  A storage bin for storing granulated calcium oxide is positioned above the pugmill mixing chamber and contains an elongat-ed opening in the bottom surface thereof which allows the bin to com-municate with the chamber.  A cylindrically-shaped rotatable meter-ing device is positioned at the bottom of the bin over the opening and contains a series of elongated axially extending slots radially displaced around the metering device so that the slots carry a mea-sured quantity of calcium oxide from the bin into the chamber through the opening as the device is rotated, the speed of rotation of the device thus determining the rate at which material from the bin is introduced into the chamber.
