Title: Aromatic conversion processes and catalysts useful therein
Inventor: BUTLER JAMES R
IPC: C07C2/66
Filed: 1990-10-30
Abstract: Aromatic conversion processes and catalysts useful therein and their preparation including alkylation and trans-alkylation processes involving alkylation of an aromatic sub-strate with a C2-C4 alkylating agent with recovery of a mono-alkylated aromatic product and liquid phase transalkylation of a polyalkylated product. Specifically, a benzene feedstock is supplied to an alkylation zone operated under liquid or vapor phase conditions with the output supplied to the transalkylation zone operated under lower temperature liquid phase conditions.   In aromatic conversion processes over molecular sieve catalysts such as zeolite Y or beta under liquid phase conditions, an aro-matic feedstock containing water is passed to a dehydration zone to provide a dehydrated feedstock of a water content of no more than 100 ppm, preferably 50 ppm or less. A specific molecular sieve catalyst comprises hydrogen zeolite beta of high surface area and low sodium content. The modified zeolite beta has a surface area of at least 600 m2/g and a sodium content of less than 0.04 wt.% Na2O. The modified zeolite beta is prepared from as-synthesized zeolite beta by sequential ion exchange treatments with intermediate calcination at a temperature of 400°-700°C for a period of two hours or longer.

Title: Motor diagnostics and electronic control for clothes dryer
Inventor: BASHARK LARRY T
IPC: D06F58/38
Filed: 1990-12-20
Abstract: ABSTRACT      A control for a clothes dryer with an induction drive motor and an electric resistance heater element.  A single sense winding is threaded through sensors monitoring drive motor current and heater current, generating an output volt-age each time the alternating motor or heater current passes through a zero-crossing.  The control monitors the ON/OFF condition of the heater and samples the lagging phase angle of the motor current, to provide an improved means of detecting when the clothes load is dry by measuring variation in motor torque due to minute differences in the way that the clothes load is tumbling from one drum revolution to the next revolution, ignoring cyclical, repetitive variation due to uneven drum rotational friction.   The control provides a clothes cooldown period with controlled moisture regain as per the user dryness selection.  In addition, numerous diagnostic conditions are monitored at the start of each cycle, or, throughout each cycle, including: 208 or 240 VAC service voltage identification; motor start detection; drum acceleration detection; empty drum detection; motor or heater open/short circuit detection; open door detection; broken belt detection; and restricted air flow detection.

Abstract: A threading insert is provided of a type that includes a mount portion and a plurality of arms radiating therefrom that each forms a pair of cutting edges, which is rugged, facilitates accurate positioning of the insert on the tool holder, encourages reliable breaking of cutting chips, and enables internal threading in a small diameter hole. One insert includes four arms (34-40, Fig. 3) radiating from a mount portion (24), with each arm having a radially outer edge (52) and a pair of opposite sides (54, 56), and forming a cutting edge (58, 60) at the interception of each side with an end of the outer edge.      The mount portion has four flat locating surfaces (42-48) lying at the sides of an imaginary square, with each locating surface lying between a pair of arms and with there being an obtuse angle (D) between each locating surface and an adjacent side of an arm. The side of each arm extends only a short radial distance before intersecting a flat locating surface, which results in rapid breaking of chips and there being a considerable distance between a central hole in the insert and each locating surface to avoid insert breakage. Each arm outer edge subtends an angle of no more than about 30°.

IPC: G01C19/56
Filed: 1991-01-21
Abstract: A motion transducer fabricated from a semiconductor material by etched exposure and release of a resiliently suspended element. Electrical sensing and/or torquing is applied to the suspended element to produce mass or vibrational sensitivities to provide a transducer for various physical parameters. In the case of a gyroscopic transducer a mass is applied to the element and may be applied in a balanced configuration on either side.  The semiconductor element and electrodes may be isolated by the use of buried PN junctions or dielectric layers, and a separately formed insulating dielectric bridge may be used to provide a support link between the suspended element and the remainder of the semiconductor material. A specific crystal orientation is useful in permitting etch control in freeing the suspended element from the remainder of the material. Suspension link stress relief is provided and a waffle construction achieved in the suspended element for use in motional transduction.

Filed: 1991-02-06
Abstract: BLOCK COPOLYMERS CONTAINING VINYL AND ARYLENE SULFIDE SEGMENTS VIA CHAIN TRANSFER                        Abstract Block copolymers of vinyl monomers and thioarylene segments are prepared from copoly(arylene sulfide-disulfides), i.e., copoly(arylene sulfides) having an appreciable guantity of disulfide linkages in the polymer chains.  Such copoly(arylene sulfides) correspond to the structure [(-A-S-)1-x (A-S-S-)x]n, wherein x is in the range of 0.5 to 0.001 based on the combined number of (-A-S-) and (A-S-S-) units.  In a preferred embodiment n is at least 200; however, polymers and prepolymers having a much lower degree of polymerization can be used, e.g., materials where n is about 25 or higher.  To prepare the block copolymers, an unsaturated monomer capable of undergoing free radical addition polymerization under the reaction conditions employed is subjected to such polymerization in the presence of the copoly(arylene sulfide-disulfide) having the above formula.  During the course of the polymerization, chain transfer occurs resulting in formation of the block copolymers.
