Title: Horizontal separator for treating under-balanced drilling fluid
Inventor: HOMAN EDWIN DARYL
IPC: B01D21/02
Filed: 1994-04-21
Granted: 1996-12-31
Abstract: The separator comprises an elongated, cylindrical, horizontal pressure vessel. An involute feed inlet introduces the drilling fluid into the top of the vessel chamber at its first end. The feed inlet is designed to reduce the flow velocity of the incoming feed stream and introduce it horizontally toward the first end head of the vessel. A weir, slanted away from the first end head, extends upwardly from a point close to the head's base. The curved head, vessel side wall and slanted weir form an inlet compartment of hopper-like configuration,designed to funnel settling cuttings to a bottom outlet for removal with an auger pump. This design enables the cuttings to be removed while drilling progresses, without the build up of cuttings piles. The vessel also has a second weir at about its midpoint, for trapping fine solids in a second compartment. Riser outlets are provided in the second compartment for water removal and in the third compartment for oil removal. Gas is removed through an overhead outlet. A process is practised whereby pressurized drilling fluid returning from a well undergoing drilling is introduced into a closed pressurized separator wherein the liquid, gas and coarse cuttings are separated, the cuttings are collected and removed from the separator as a separate stream while drilling fluid continues to enter the separator, and the liquid and gas are also separately removed from the separator.

Abstract: A method of operating a torque transmitting system with a hydrodynamic power transmission and with a friction clutch which bridges the power transmission, involves controlling a lock-up clutch and the hydrodynamic power transmission of such system so that clutch slip is present.      The method of operating involves a regulation of torque and includes the breaking up of input torque furnished by a prime mover into a torque which is to be transmitted by the power transmission and a torque which is to be transmitted by the lock-up clutch. The lock-up clutch includes an annular piston which is disposed between the cover of the power transmission and the turbine wheel. The radially outer portion of the piston constitutes a clutch disc and its radially inner. portion is mounted on a complementary sealing hub. The power transmission is "soft" and exhibits a flat progress of the primary characteristic curve as well as a wide secondary characteristic curve, i.e., a wide torque conversion range.

Abstract: A stearate-matrix, pre-spotter composition in solid stick form to be applied by direct contact to stained areas of fabric, thereby transferring the composition to the stained areas of the fabric.  The composition includes an alkyl aromatic sulfonic acid and/or sulfonate, at least one nonionic surfactant, and an enzyme uniformly dispersed throughout a semi-hard stearate matrix.  By the addition of sodium bicarbonate, the composition optimizes the pH to promote enzyme action, while simultaneously achieving a satisfactory drop point for shipping and warehousing.          At pH levels from 8.2 to 9.0, acceptable hardness and transferability are still achieved, which was previously thought not to be possible without the addition of a critical amount of certain salts.  The further addition of sodium bicarbonate in an encapsulated form directs the sodium bicarbonate-driven soil and stain removing capabilities of the composition to the point of application on the fabric.

Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate. An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12). Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of  the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate. Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly, (Fig. 6)

Abstract: A portable chainsawmill that enables on site processing of timber into dimension lumber ready for construction. The cutting means is a stationary, vertically upright mounted chainsaw with a special throttle control. The topside of the sawbar rips the timber and propels the sawdust in a downward direction. The sawmount is designed for sideways positioning of the chainsaw between cuts. The sawmount permits quick removal of the chainsaw for recharging of resevoirs or maintenance. The timber conveyance is a rolling trolley that operates on a flat deck. The trolley is kept in line with allignment guides. The timber normally rests on a mill table which is mounted on the trolley. The timber is secured with a suitable means. The mill table has slots in it which allow the sawbar nose to pass under the timber and sawdust to pass. An auxilliary table on the trolley permits slabs to be cut off of large logs when necessary and also serves as a catchment or storage area for lumber being processed. The trolley is pulled through the sawbar with a winching apparatus. Sawdust is propelled through an opening in the deck to a pile under the deck.      This complete chainsawmill is modular and very easy to erect in remote locations.
