Abstract: A method for dispensing a foamed material onto a substrate surface, including: generating a relative movement between the substrate surface to be coated and an exit opening of a material dispensing apparatus, mixing at least two material components in a mixing device to provide a free-flowing, foamable dispensing material, generating a pressure differential between the mixing device and the dispensing region located downstream in the direction of flow from a discharge cross-section of the exit opening, conveying the dispensing material from the mixing device for the dispensing material to the exit opening, and discharging the dispensing material from the exit opening onto the substrate surface. The dispensing material be kept under such a pressure in the region adjacent to and upstream from the discharge cross-section of the exit opening that the dispensing material in this region has a foaming rate that is less than 10% of the foaming rate which ensues at the end of the foaming process.

Abstract: A device for producing a foam material, comprising a gas supply line which is connectable at a first end to a gas source, a material supply line which is connectable at a first end to a material supply source, a material transporting device which is connected to a second end of the material supply line, and a mixing device into which material and gas may be introduced and in which they may be mixed together, and from which a homogeneous mixed foam is deliverable from an output orifice.

Abstract: Aspects of the present invention provide apparatus and methods of releasing a plug. In one aspect, a plug and ball seat assembly for releasing a plug is disclosed. The assembly is selectively maintained in a housing using a mounting system. The plug and ball seat assembly includes a ball seat selectively connected to the plug. The mounting system is designed such that disengaging the ball seat from the plug also disengages the plug from the housing, thereby releasing the plug. In another aspect, a method of releasing a plug includes selectively connecting a ball seat to the plug and disposing the plug and ball seat assembly within a tubular. When the plug is ready for release, the ball seat is disconnected from the plug and allowed to move axially relative to the plug. In turn, the plug and ball seat assembly disconnects from the tubular and releases downhole.

Abstract: An abdominal exercise adapter comprising two wedges and a telescopic pole extending between the two wedges. Each wedge has a vertical edge, a horizontal edge, and a third edge extending between the former two. The third edge is concave shaped. A channel runs through the bottom of the horizontal edge. Vertical members of a lower frame of an abdominal exercise device fit in the channels of each wedge, thereby allowing the adapter to rest firmly on the exercise device. Vertical members of an upper frame of the exercise device cradle in the third edge of the adapter, thus preventing the frame from returning to a resting position. When the adapter is in use with an exercise device, a user endures a more challenging exercise session since the wedges of the adapter block the upper frame from descending past a certain point. Thus, the user is forced to keep her head off the head rest, and her stomach and abdominal muscles remain tense.

Abstract: A lawn mower deck protecting device including a lawn mower deck mounting portion comprised of a right side brace and a left side brace secured to the deck of the lawn mower. A stress bar couples with a handle of the lawn mower and the right side brace of the lawn mower deck mounting portion.

Abstract: A hairspray composition is described that includes a nonionic polymer and an anionic polymer. The nonionic polymer is formed from monomers having at least one unneutralized carboxylic acid. The anionic polymer is identical to the nonionic one, except that all of the carboxylic acid groups are in salt form. Advantageously, the composition further includes an acrylic resin, most especially an amphoteric one. Best results are achieved when the acrylic resin is neutralized with a relatively small cation such as potassium and a second cation of a water soluble fatty amine. These compositions employ water as the carrier and dimethyl ether as propellant.

Abstract: Hair styling mousse compositions are provided based on a combination of water soluble film-forming resin, an amphoteric surfactant and a propellant system. The system requires a combination of C.sub.3 -C.sub.5 alkane hydrocarbon and dimethyl ether in a respective weight ratio from 4:1 to 1:2.

Abstract: An aqueous hair treatment composition is provided that includes a water-soluble polymer having a solution viscosity at 10% in water of less than about 20,000 cps at 25.degree. C., and a latex of water-insoluble polymeric particles dispersed in water and having a glass transition temperature between 250 and 300.degree. K., the average particle size being no higher than about 3 microns. Preferably the latex particles are formed from respective monomers by emulsion polymerization.

Abstract: A ported float shoe and a landing collar are attached at one end of a casing string and a sliding air trapping insert attached by shear pins at the other end. The air trapping insert includes a fluid flow passageway blocked by a plug attached by shear pins to the insert. The air trapping insert and float shoe form an air cavity within the string portion. After running the string into a deviated well bore, the shear pin supported plug is pressure actuated open to allow air to be vented and drilling mud to flow into the cavity. A wiper plug followed by pressurized cement slurry shears away the attached insert, opens the float shoe, moves the insert to the bottom of the well, and allows cementing of the casing. Moved apparatus (near well bottom) forms a single drillable unit until drilled out in normal post-cementing operations. The flotation method reduces insertion drag and the related chance of a differentially stuck casing, and avoids the separate removal steps required by current flotation techniques.

Abstract: Tie-strap comprising dual elongated body portons with holding eyelet projections at opposite ends, and a bridging member connecting side portions of the upper areas of the strap and the eyelet projections are affixed around a cable structure joined by coaxial connectors in a manner which allows the bridging member to lie taut in parallel relationship with said cable and across said connector in order to prevent separation of said connector.

Abstract: A metal journal forging has a central body portion and four substantially equal legs circular in cross section which are integral with the body portion with the axis of each leg being at substantially a right angle to the axis of each adjacent leg. A curved portion extends between each adjacent pair of legs. The flow lines of the grain structure of the forging in each quadrant formed by the axes of the legs are substantially parallel the contours of the exteriors of the legs and curved arcuate portion in the quadrant. The method for forming a metal cruciform journal forging comprises placing a metal forging billet in a die assembly having a main cavity for the reception of the metal cylinder and a pair of opposed cavities branching off from the main cavity at 90.degree. to the main cavity.

Abstract: Thickened, pourable liquid bleaching compositions which have been thickened with the aid of two different detergent-active materials, e.g. a tertiary amine oxide with a saturated fatty acid soap or an alkali metal sarcosinate often show a decrease in viscosity on storage of the composition.By inclusion of a third, synthetic detergent of the sulphate or sulphonate type, e.g. an alkylethersulphate, compositions are obtained with a significantly reduced decrease of viscosity during storage, particularly over longer periods and at higher storage temperatures.The compositions are useful for bleaching hard surfaces.

Abstract: A ship navigation and handling training simulator comprises a console for use by an instructor and a console for use by a student navigator. Each console has a visual display unit with a screen to provide a mimic display of the ship and environmental information, and the instructor console is associated with two groups of controls for setting in, respectively, the environmental and display information applicable to the navigational or ship handling exercise to be performed and information representing ship/tug control decisions by the student. The consoles are interconnected by a voice link so that the instructor can initially set the environmental and display controls and subsequently adjust the group of controls for ship/tug control in accordance with vocal instructions from the student transmitted via the voice link.
