Filed: 1988-10-12
Granted: 1992-06-02
Abstract: A DRAG BIT FOR DRILLING IN PLASTIC FORMATIONS WITH MAXIMUM CHIP CLEARANCE AND HYDRAULICS  FOR DIRECT CHIP IMPINGEMENT    ABSTRACT     An improved bit and method for cutting plastic and sticky rock formations, which tend to cause bit balling, is provided by a drag bit having a cutting face formed of a plurality of generally radially extending open arched blades.  Each arched blade is provided with a cutting face and defines a cavity beneath the arch to the bit body.  In a preferred embodiment, the cutting elements on the arched blade are a plurality of synthetic polycrystalline diamonds which are cut, sized and shaped to conformally fit with each other so as to present a substantially diamond-only surface as a cutting surface of the bit. Hydraulic nozzles are defined in the bit body beneath and azimuthally behind the arches formed by each blade.  The nozzles direct hydraulic flow across the cavity under the arch and across each portion of the cutting face on the arch.  As a result, when cutting, substantially only a diamond surface is provided for shearing the rock formation or contacting with velocity any portion of the plastic rock formation.  Once the rock chip is exuded upwardly across the diamond face of the cutter, it is subjected to a directed hydraulic flow which peels the chip from the diamond face and transports it into the open cavity defined underneath the arched blade.  The cavities under the arched blade form an open toroidal space around the bit and freely communicate with a plurality of large open waterways and junk slots.  Large plastic fragments may then be cut, peeled from the face of the diamond cutters, and flushed through the waterways up the junk slots.

Abstract: PIEZOELECTRIC PHASE LOCKED LOOP CIRCUIT       Abstract of the Disclosure A structural member having a piezoelectric transmitter film and a piezoelectric receiver film adhered thereto.  The transmitter film produces a vibration upon activation by a voltage controlled oscillator which forms part of a phase-lock loop circuit.   The vibrations of the rigid member generate electric signals on a second receiver film, which feed into a phase comparator. The other input of the phase comparator is the voltage controlled oscillator.      The phase comparator will output a dc signal proportional to the difference in phase between the two signals.   When the structural member becomes damped the phase comparator will go  into saturation, thereby producing a voltage which can activate an alarm signal or other device.

Abstract: This invention is directed to conducting chemical reactions in reverse micelle or microemulsion systems comprising a substantially discontinuous phase including a polar fluid, typically an aqueous fluid, and a microemulsion promoter, typically a surfactant, for facilitating the formation of reverse micelles in the system.  The system further includes a substantially continuous phase including a non-polar or low-polarity fluid material which is a gas under standard temperature and pressure and has a critical density, and which is generally a water-insoluble fluid in a near critical or supercritical state.  Thus, the microemulsion system is maintained at a pressure and temperature such that the density of the non-polar or low-polarity fluid exceeds the critical density thereof.  The method of carrying out chemical reactions generally comprises forming a first reverse micelle system including an aqueous fluid including reverse micelles in a water-insoluble fluid in the supercritical state.  Then, a first reactant is introduced into the first reverse micelle system, and a chemical reaction is carried out with the first reactant to form a reaction product.  In general, the first reactant can be incorporated into, and the product formed in, the reverse micelles.  A second reactant can also be incorporated in the first reverse micelle system which is capable of reacting with the first reactant to form a product.

Abstract: ABSTRACT      An apparatus and a method are disclosed for the removal and the recovery of washcoat remaining in the channels of freshly coated monolithic or honeycombed catalytic carriers.          The carrier is inserted into a chamber from above and tightly fitted therein at least with the lowest part of the carrier therein.  The chamber is fitted with a collection area and a runoff located thereunder.  The runoff leads via a shutoff valve into a separation vessel under a vacuum.  The opening and closing of the shutoff valve causes air to be aspirated through the carrier channels, which are open at the top or are gradually opened by means of a slotted slide.  This action causes the washcoat remnants to he transferred into the separation vessel, where they can be collected in the sump and are then pumped off.  The apparatus can be used in systems for manufacturing catalysts for cleaning exhaust gases.

Granted: 1995-02-14
Abstract: Sensitive deep ultraviolet resists are formed utilizing a material that undergoes decomposition to form an acid together with a polymer including a chain scission inducing monomer such as sulfonyl units and substituent that undergoes reaction to form an acidic moiety when subjected to the photogenerated species. An exemplary composition includes poly(t-butoxycarbonyloxystyrene-sulfone) and 2,6-dinitrobenzyl-p-toluene sulfonate. The sulfonate decomposes to form sulfonic acid upon irradiation. This acid reacts with the polymer group to form an acid functionality while the sulfone moiety of the polymer induces scission. As a result, the irradiated portions of the resist material are soluble in ionic solvents while the unirradiated portions are not.
