Abstract: A fireproof, compressible, intumescent, elastomeric material useful to seal expansion joints, curtain wall gaps and penetrations in floors and walls in order to prevent the passage of flame and smoke. A seal of the material retains strength before and after exposure to fire and provides superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire. The composition of this compressible, fireproof material consists of elastomers, vulcanizing agents, fillers, softening agents, and an intumescent. This fireproof material may be in cellular or noncellular form with various degrees of compressibility and softness.      It can be produced in sheets, molded parts, and continuous length strips. It may be vulcanized or nonvulcanized.

Abstract: The invention provides a metallocene catalyst for use in preparing syndiotactic polyolefins. The catalyst comprises a bridged metallocene in which one of the cyclopentadienyl rings is substituted in a substantially different manner from the other ring. It was discovered that this type of catalyst is highly syndiospecific, and it also produces a polymer with a novel microstructure. The invention further includes the use of one or more of the catalysts in a polymerization process. The catalyst is generally described by the formula   wherein each Cp is a cyclopentadienyl or substituted cyclopentadienyl ring; each Rn and R'm is the same or different and is a hydrocarbyl radicals having 1-20 carbon atoms; R" is a structural bridge between the two Cp rings imparting stereorigidity to the catalyst; Me is a group 4b, 5b, or 6b metal from the Periodic Table of Elements; each Q is a hydrocarbyl radical having 1-20 carbon atoms or is a halogen; 0  k  4; 0 n  4; 1  m  4; and wherein R'm is selected such that (CpR'm) is a sterically different ring than (CpRn).

Abstract: ABSTRACT OF THE DISCLOSURE A robotic palletizer including a vertical column, a telescoping horizontal arm mounted for vertical movement along the column and a hand assembly mounted at the end of the horizontal arm.  A pair of photodetectors, movable with the hand assembly, sense the presence and location of cartons in place on a pallet being loaded and signal the palletizer when the vertical height and horizontal extension of the hand assembly are sufficient to a place cartons in the proper position for loading onto the pallet.  A circuit controls operation of the palletizer in accordance with the sizes and shapes of the cartons and pallets and permits limited variation of the loading pattern provided by the palletizer.  Separate conveyors transport cartons to the palletizer for loading and remove loaded pallets from the palletizer upon completion of the loading cycle.

Abstract: PIPELINED FLOATING POINT ADDER      FOR DIGITAL COMPUTER                   ABSTRACT      A system for subtracting two floating-point binary numbers in a pipelined floating-point adder/subtractor by aligning the two fractions for substraction; arbitrarily designating the fraction of one of the two floating-point numbers as the subtrahend, and producing the complement of that designated fraction; adding that complement to the other fraction, normalizing the result; determining whether the result is negative and, if it is, producing the complement of the normalized result; and selecting the larger of the exponents of the two floating-point numbers, and adjusting the value of the selected exponent in accordance with the normalization of the result. The preferred system produces a sticky bit signal by aligning the two fractions for subtraction by shifting one of the two fractions to the right; determining the number of consecutive zeros in the one fraction, prior to the shifting thereof, beginning at the least significant bit position; comparing (1) the number of positions the one fraction is shifted in the aligning step, with (2) the number of consecutive zeros in the one fraction; and producing a sticky bit signal when the number of consecutive zeros is less than the number of positions the one fraction is shifted in the aligning step, the sticky bit signal indicating the truncation of at least one set bit during the aligning step.

Abstract: TOPOGRAPHIC PATTERN DELINEATED POWER MOSFET     WITH PROFILE TAILORED RECESSED SOURCE     ABSTRACT OF THE DISCLOSURE       A dopant-opaque layer of polysilicon is deposited on gate oxide on the upper substrate surface to serve as a pattern definer during fabrication of the device.  It provides control over successive P and N doping steps used to create the necessary operative junctions within a silicon substrate and the conductive structures formed atop the substrate.  A trench is formed in the upper silicon surface and a source conductive layer is deposited to electrically contact the source region as a gate conductive layer is deposited atop the gate oxide layer.  The trench sidewall is profile tailored using a novel O2-SF6 plasma etch technique.  An oxide sidewall spacer is formed on the sides of the pattern definer and gate oxide structures, before depositing the conductive material.  A planarizing layer is applied and used as a mask for selectively removing any conductive material deposited atop the oxide spacer.  The polysilicon layer on the oxide is reduced in thickness during trenching so that any conductive material deposited atop the spacers protrude upward for easy removal of excess, conductive material.  The sidewall spacers can be sized, either alone or in combination with profile tailoring of the trench, to control source-region width (i.e., parasitic pinched base width) and proximity of the source conductor to the FET channel.  Electrical contact between the source conductive layer and the source regions is enhanced by forming a low-resistivity layer between them.
