Abstract:
This invention relates to peroxygen bleaching activator compounds and bleaching compositions. The peroxygen bleach activator compounds, used in combination with peroxygen bleach compounds which yield hydrogen peroxide in an aqueous solution, provide effective and efficient bleaching of textiles over a wide range of temperatures. In a highly preferred embodiment the bleaching compositions of the invention are detergent compositions.
Abstract:
A low modulus, one component, room temperature vulcanizable silicone elastomer which has very good oil resistance properties as well as high elongation. The silicone elastomer which has low volatility comprises a silanol terminated diorganosiloxane base polymer, a trimethylsilyl terminated diorganopolysiloxane, generally a tin catalyst, as well as a oxime crosslinking agent and specific low moisture fillers, usually calcium carbonate. The material is ideally suited as a gasket sealant as well as a formed-in-place gasket and can be utilized on internal combustion engines such as automotive engines as a sealant for an oil pan, valve cover, side seals and the like.
Abstract:
A vibration attenuator seat includes a seat assembly with a pair of paralleled shafts slidable in horizontally positioned, ultra low friction, linear bearings mounted in a base assembly. A seat adjustment assembly has a bottom part which is a part of the base assembly and a latch in its top part for engaging the bottom part to lock the top and bottom parts in a plurality of positions. A pin secured to the top part of the assembly centers the seat assembly relative to the top part by being connected by one preloaded, closed-coil spring to one end of the seat assembly and by a second preloaded, closed-coil spring to the other end. The body of a shock absorber positioned parallel to the shafts is secured to the pin and the rod is secured to the seat assembly. The latch allows positioning adjustment of the seat assembly relative to the base assembly and the shock absorber attenuates shocks and vibrations between the base and seat assemblies while the springs provide preloaded biasing towards the adjusted position.
Abstract:
A disposable pressure vessel includes a gas valve containing cylindrical cap encircled by an O-ring. The cap is bonded to an annular flared portion of a generally cylindrical rubber bladder and is disposed in a hollow cylindrical housing such that the cap compresses the flanged portion of the bladder against a shoulder in the cylindrical housing. The cap is held in place by three equally circumferentially spaced, lanced portions of the cylindrical housing and the O-ring seals the interior of the cylindrical housing from the exterior.
Abstract:
A belt press having a frame with a first belt and a second belt rotatably mounted on the frame. A curved inlet guide is movably carried on the frame. The inlet guide has a decreasing radius of curvature from an inlet end to an exit end. A positioning assembly is mounted on the frame and is attached to the inlet end of the inlet guide to raise and lower the inlet end of the inlet guide.
Abstract:
Assembly of the combustor dome in a gas turbine engine is facilitated by providing a self-fixturing configuration. The combustor dome assembly is made up of a dome plate having a plurality of swirler assemblies mounted therein. Each swirler assembly is provided with a locating pin that extends between the dome plate and the swirler assembly for positioning the swirler assembly with respect to the dome plate without the use of fixturing tools. Preferably, the swirler assembly includes a swirl cup and an outlet sleeve mounted in the dome plate. The locating pin is pressed into a hole formed in the swirl cup. One end of the pin is received in a slot formed in the dome plate, and the other end of the pin is received in a slot formed in the outlet sleeve. Thus, the locating pin sets the circumferential orientation of the swirler assembly in relation to the dome plate. A shoulder on the swirl cup sets the cup axially with respect to the dome plate, and a shoulder on the outlet sleeve sets the sleeve axially with respect to the swirl cup.
Abstract:
Multi-hole film cooling of combustor liners is enhanced by providing clustered groups of cooling holes in areas of the liners that would otherwise experience a loss of cooling film effectiveness. The combustor liner is made up of a shell having first and second groups of cooling holes formed therein. The cooling holes of the second group are more closely spaced than the cooling holes of the first group. The second group of cooling holes is located on an area of the shell where the cooling film effectiveness is degraded. Preferred locations include a region of the shell that is subjected to swirl impingement and a spot immediately downstream of a large opening in the shell such as a dilution hole, a borescope hole or an igniter port hole.
Abstract:
Included is a liquid detergent composition comprising detersive surfactant, proteolytic enzyme, a detergent-compatible second enzyme, and an aryl boronic acid of the structure: ##STR1## where X is selected from C.sub.1 -C.sub.6 alkyl, substituted C.sub.1 -C.sub.6 alkyl, aryl, substituted aryl, hydroxyl, hydroxyl derivative, amine, C.sub.1 -C.sub.6 alkylated amine, amine derivative, halogen, nitro, thiol, thiol derivative, aldehyde, acid, acid salt, ester, sulfonate or phosphonate; each Y is independently selected from hydrogen, C.sub.1 -C.sub.6 alkyl, substituted C.sub.1 -C.sub.6 alkyl, aryl, substituted aryl, hydroxyl, hydroxyl derivative, halogen, amine, alkylated amine, amine derivative, nitro, thiol, thiol derivative, aldehyde, acid, ester, sulfonate or phosphonate; and n is 0 to 4.
Abstract:
A method for controlling weeds and undergrowth and for treating plants in agricultural settings is disclosed. The method is characterized by first applying a spray of hot water to the plant, and then applying a foam blanket to the sprayed plants, whereby heat from the hot water spray is held against the plants.
Abstract:
An apparatus and method for controlling vegetation, as well as insect infestation, as are typically encountered in agricultural environments is disclosed. The apparatus is characterized by its construction to include a high pressure pump liquid spray material may be applied to vegetation at a pressure from about 100 psi to as much as about 4,000 psi. The apparatus further includes a heater whereby the liquid spray material may be heated to a temperature of from about 100.degree. F. to about 240.degree. F. before it is sprayed. The apparatus is constructed so that it can be attached to a standard tractor for ease of use. The method of this invention is characterized by its utilization of a high pressure spray so that agricultural chemicals in amounts from virtually 0% to about 50% of their current recommended dose rates can be used with efficacy.
