Abstract: ABSTRACT OF THE DISCLOSURE:           A light duty microemulsion liquid detergent composition, use-ful for removing greasy soils from surfaces with both neat and dilute forms of the detergent composition, includes a moderately water soluble complex of anionic and cationic surfactants, in which complex the anionic and cationic moieties are in essentially equivalent or equimolar proportions, an anionic detergent, a co-surfactant, an organic solvent and water.  Preferably, the complex component is one in which the anionic and cationic moieties include hydrophilic portions or substituents, in addi-tion to the complex forming portions thereof, the anionic detergent is a mixture of higher paraffin sulfonate and higher alkyl polyoxyethylene sulfate, the co-surfactant is a poly-propylene glycol ether, a poly-lower alkylene glycol lower alkyl ether or a poly-lower alkylene glycol lower alkanoyl ester, and the organic solvent is a non-polar oil, such as an isoparaffin, or an oil having polar properties, such as a lower fatty acid ester or a lower fatty alcohol ester.         Also within the invention are the described complex, preferably one of equimolar proportions of sodium C12-14 alkyl diethoxy ether sulfate and C12-14 alkyl-bis(2-hydroxyethyl) methylammonium halide, and processes for manufacturing the liquid detergent composition and for removing grease from laundry and hard surfaces by use of such a liquid detergent composition, especially in neat form, in which latter process significantly improved cleaning results, compared to that obtained when using control detergent compositions.

Title: Curable rubber bladder stocks having reduced viscosity
Inventor: STUHLDREHER TERRENCE M
IPC: C08L21/00
Filed: 1990-04-10
Abstract: ABSTRACT OF THE DISCLOSURE            A curable rubber bladder stock containing esters of ricinoleic acid or derivatives thereof has reduced viscosity as compared to stocks containing castor oil.  The rubber stocks of the present invention gener-ally retain a very high percentage of the initial cure tensile strength and have improved modulus as compared to castor oil, both upon initial cure and upon aging.  Lower viscosity and higher modulus of the rubber stocks of the present invention readily permit the production of thin-ner bladders.  The bladders can fit within an article such as a tire during vulcanization of the tire as in an automatic vulcanizing press.  Thinner bladders effect a greater heat rate and result in shorter cure times for articles such as tires.  The esters of ricinoleic acid and derivatives thereof have the formula   where R is H or    where R1 is an aliphatic, preferably an alkyl, having from 1 to 12 carbon atoms, desirably from 1 to 4 carbon atoms, and preferably 1 carbon atom, i.e., methyl, and R2 is an aliphatic, desirably an alkyl, having from 1 to 12 carbon atoms and preferably from 1 to 4 carbon atoms.

Title: Sealing gland construction for use in hydraulic unit joints
Inventor: DELERY OLIVER S JR
IPC: F16L19/00
Filed: 1990-08-20
Abstract: ABSTRACT OF THE DISCLOSURE     A sealing gland construction for use in connection with hydraulic unit joints.  Receptacles are provided at the joint for enlarged and compressible heads disposed on each end of the sealing gland.  One receptacle is located on an inner wall of a female or bell end of one pipe and another receptacle is located on the exterior wall or a male or spigot end of an adjacent pipe.  The enlarged heads of the sealing gland extend perimetrally around their associated female and male ends of the pipe and are adhesively secured within the receptacles.  By making the compressible heads larger than the dimensions of the receptacle they are maintained under compression both horizontally and vertically.  In the assembled joint position, the male end and its receptacle have been inserted into the female end past its receptacle so as to effect a fluid seal which is encased within the walls of said pipes and which remains sealed even in the event of a slight discoupling of the joint.  In another embodiment, only the female pipe end is provided with a receptacle for an enlarged, compressible head.  The opposite end of the sealing gland is clamped and adhesively secured to the male end.  In the assembled position, the point of attachment is inserted beyond the receptacle in the female end to reach a comparable result.

Abstract: CONTROL METHOD FOR AUTOMATIC  TRANSMISSION GARAGE SHIFTS         ABSTRACT OF THE DISCLOSURE         Garage shifts are accomplished at shifts from neutral to forward or reverse or between forward and reverse.  An off-going clutch is released at the beginning of the shift for shifts between forward and reverse; shifts from neutral have no off-going clutch. The on-coming clutch has a fill time at maximum pressure, a lower increasing pressure ramp to begin engagement as indicated by pullup or pulldown, and a closed-loop control triggered by pullup or pulldown. The closed-loop control commands the pressure to control the turbine speed to a calculated profile to bring the speed to a target value.  When the target value is attained the closed-loop control is terminated and maximum pressure is applied.  For low speed shifts and for a high speed shift between forward and reverse, the target value is zero.  For high speed shifts from neutral the target value may be either above or below the initial turbine speed.

Title: Method and system for measurement of fluid flow in a drilling rig return line
Inventor: ZANKER KLAUS
IPC: E21B21/08
Filed: 1990-12-13
Abstract: ABSTRACT OF THE DISCLOSURE      Improved methods and systems are provided for determining a volumetric flow rate of mud in a return line without the aid of a velocity probe.  A mud level sensor is located in a return line chimney preferably in close proximity to the bell nipple.  The sensor senses the height of the mud flowing in the return line.          Where an ultraonsic transceiver is used as the sensor, temperature sensors in the chimney and return line determine a temperature gradient in the return line which provides a speed of sound correction as does a target at a known distance from the transceiver.  A computer receives the uncorrected mud height and the speed of sound information, and determines the flow-out volume of the mud.  Flow-out volume is related to the mud height, the geometry of the return line, and mud parameters.  In a more complete system, the computer calibrates the determined flow-out volume with the flow-in volume, and provides a correction factor which is used to provide a corrected flow-out determination.  The computer also monitors delta flow (flow-out minus flow-in), and based on the rate of change of delta flow determines when an undesirable condition such as a kick or fluid loss  occurs.  Where the system is to be used on rig which is subject to movement (e.g. a floating rig), an angle sensor is employed to help determine instantaneous flow-out, and the flow out determinations are averaged over the movement cycle of the rig as determined by heave position sensors available on the rig.

Title: Removal of the folding carrier and sidebands from an unfolded video signal
Inventor: STROLLE CHRISTOPHER H
IPC: H04N11/02
Filed: 1991-02-12
Abstract: Apparatus is disclosed for processing video information which is reproduced from a magnetic recording medium in a video cassette recorder. The luminance portion of the video signal, which is "folded" about a sampling frequency carrier before recording on magnetic tape, is unfolded after being read from the magnetic tape to restore the bandwidth of the signal, and is applied in parallel through horizontal and vertical comb filters. The combined output of the horizontal comb filter and the vertical comb filter may include incompletely cancelled horizontal and vertical components of the folding frequency and sidebands due to the effects of picture contents. Edge detector means receptive to the unfolded video signal responds to an encountered brightness edge, and generates a signal which varies the proportions of the video outputs of the horizontal and vertical comb filters in the combined output.
