Abstract: The invention relates to a new catalyst system that improves the heat transfer capability of a butyl reactor slurry process system in the production of isobutylene-based polymers in continuous slurry polymerization processes. The process is carried out in an anhydrous polymerization system containing a mixture of the monomers in a polar diluent along with a Lewis acid and a C5 or greater initiator having a tertiary halide.

Abstract: An cervical drug delivery apparatus having an absorbent cylindrical structure with a cervical cap attached to one end. One or more therapeutic agents are applied to the internal surface of the cervical cap. The cervical drug delivery apparatus is housed within an applicator and inserted into a patient's vagina. Upon deployment of the cervical drug delivery apparatus, the cervical cap is automatically positioned over the patient's cervix providing for the direct application of the therapeutic agents on the patient's cervix. Alternative features of the cervical drug delivery apparatus include, a break-away cylindrical structure, a collapsible support structure for the cervical cap, an inflatable means for supporting the cervical cap, and the ability of the cylindrical structure and/or the cervical cap to contain one or more therapeutic agents that can be delivered by outside means.

Abstract: A funnel structure with different cross-sectional shaped bowl and spout for transferring viscous food materials from one vessel to another, to eliminate the problem of entrapped air causing splashing. The funnel has a circular bowl and a spout with a square cross-section which can be offset from the circular bowl.

Abstract: A partially baked, laminated dough product such as a croissant or a pastry is made by heating the dough product preferably in an impingement oven to a temperature of about 200.degree. F. to about 210.degree. F. and then immediately freezing the partially baked dough product preferably in a co-current liquid nitrogen freezer so as to prevent a collapse of the partially baked dough product.

Abstract: A process and apparatus for cutting and gouging a workpiece wherein solely a vacuum is used as the operative molten metal removal force. Isolating the atmosphere surrounding the arc as it melts the workpiece while evacuating the atmosphere as the melting proceeds thus facilitating a better cut or gouge with lower process generated noise and removal of process generated fume.

Abstract: An exothermic cutting electrode or burning bar provided with a coating containing oxidizing material, arc stabilizing material and a binder with portions of reduced coating thickness along the length of the electrode.

Abstract: A swing for both arcuate and rotational motion has a disc platform for passengers and multiple, congruently attached support strands adapted for securing to a horizontal support member. The bight of a strand passes around the support member such that two free ends of the strand may pass through the disc to locks to adjustably secure the ends to the disc. The strand pairs are fixed to the horizontal support member at spaced positions on the member congruent with the position of the strands on the disc. The disc is provided with a peripheral rim having top and bottom walls. Extending through the walls are a plurality of spaced apart vertical apertures. The lower wall is provided with a depression placed adjacent each aperture. Extending across the depression and spaced from the bottom of the depression is a rigidly attached lock bar.
