Abstract: ABSTRACT OF THE DISCLOSURE          A system for the dispensing of literature to objects, such as containers carried by a conveyor, includes a tape for the application of adhesive to literature, and a device for the separation of the literature from the tape to permit the securing of the literature, adhesively, to the containers.  A drive mechanism is provided for advancing the tape through successive increments of distance, each incre-mental distance being equal to the size of one piece of literature.  A hopper dispenses the literature to the tape, one piece at a time.  Application of the pieces of litera-ture to the objects is accomplished by a roller or brush.          The literature separation device includes a bar having an edge about which the tape is bent to free the literature from the tape as the tape advances around the edge.  The adhesive is retained by the literature during the separation from the tape so as to permit the adhesive attachment of the pieces of literature to the containers.

Abstract: Abstract The present invention relates to a method of installing one or more subsea templates at preselected sites on a seabed.  The method is comprised of the steps of providing a column stabilized variable draft semi-submersible drilling rig having at least one submersible hull including a unit for supporting a template on the hull, a derrick, primary apparatus associated with the derrick for raising and lowering a riser through a moon pool on the rig spaced laterally from the hull, and secondary hoisting apparatus on the rig including a cable unit adapted to be connected to the template.  At least one submersible template is adapted to have controllable positive and negative buoyancy.  The steps further include loading the template on the support unit for the template using a crane and at least one of the hoisting apparatus to position the template over the support unit; lowering the template onto the support unit and ballasting the template to shift the weight of the template to the support unit; and transporting the template to a predetermined site on the seabed with the drilling rig.  The method further includes the steps of connecting the template to the primary and secondary hoisting apparatus; venting ballast from the template to float the template free of the support unit while controlling the position of the template with the hoisting apparatus; taking up the primary hoisting apparatus and slacking off the secondary hoisting apparatus to position template under the moon pole; and lowering the template to the seabed with the hoisting apparatus.

Abstract: ABSTRACT     The disclosed chip is suitable for VLSI dRAMS.          The memory cell includes a bipolar transistor, a JFET, and a capacitor.  The capacitor comprises a MOSFET which is operated only in the accumulation mode.  Each cell requires only three lines.  On a p-substrate, which comprises the collector of the bipolar, the cell layers are:- an n-well which comprises the channel of the JFET and the base of the bipolar; a p-region, which comprises the gate of the JFET, the emitter of the bipolar, and the bottom plate of the capacitor; an oxide layer; and a conducting layer; arranged as a vertical stack in that order.  The latter two layers are the insulator and the top plate of the capacitor.  The source and drain of the JFET are respective n+ regions  placed one either side of the stack.  The n-well can be deep and hence can be compatible with conventional CMOS technology.  The chip has full read, write, and refresh capability; is relatively easily manufactured; and can be considerably scaled down without losing performance.
