  • Patent number: 5527194
    Abstract: In a marine drive (10), a nonrotational thrust sensing device (202 or 204) is placed between the stationary housing (26') and rotating propeller shaft (40' or 42') to measure the thrust output of a propeller (12 or 14) by measuring the equal and opposite force applied to the housing by the propeller shaft (40' or 42'). A thrust bearing (214 or 248) is situated between the rotating shaft and the nonrotating thrust sensing device. A thrust ring (246) and adapter (250) provide adoption of the thrust sensing device to a particular housing and shaft configuration. In a marine drive having counter rotating coaxial propeller shafts, first and second thrust sensors individually sense the thrust of inner and outer propeller shafts, respectively, to provide separate sensed thrust for each.

  • Patent number: 5002438
    Abstract: A method for lining or relining a sewer manhole, apparatus comprising an improved leak resistant manhole, and a cementitious mixture for lining/relining manholes. A homogeneous, monolithic, cementitious liner is spray applied in place within a concrete or brick-and-mortar manhole infrastructure without forms, webbing, or re-bar. A manhole to be serviced is first located and spray cleaned with water. Loose concrete and mortar fragments of the original structure are forcibly removed. A cementitious mixture is spray-applied to the interior surfaces of the manhole to create a continuous, monolithic interior liner. This lining is configured substantially identically to the internal shape and geometry of the manhole. When the liner sets after installation, a substantially impervious water and chemical resistant barrier prevents manhole ingress/egress by ground water.

  • Patent number: 4673413
    Abstract: An apparatus for treating carbonaceous material, e.g. waste oil by effecting the gasification thereof to produce a relatively high BTU content gas to supplement or substitute for natural gas. This is attained by a furnace in which the products of combustion are utilized to separately generate steam and to preheat a supply of carbonaceous material which may be mixed with water. The generated steam is mixed with the preheated carbonaceous material and passed through a premixing and/or a primary dynamic mixer wherein the preheated carbonaceous material and steam mixture is further heated to a temperature ranging between 1600.degree.-1800.degree. F. to effect a partial gasification of the carbonaceous material. The partially gasified material is thereafter directed through one or more secondary dynamic mixing chambers to be further heated in the presence of additional steam to complete the gasification thereof.

  • Patent number: 4448536
    Abstract: A mixing device for preparing wet mix cementitious products comprised of large aggregates includes a pair of generally tubular, horizontally disposed casings which form a mixing chamber, and which share common, open sides. An open top of the chamber receives raw materials to be mixed. Elongated central impeller shafts extend longitudinally, generally coaxially within each of the casings, rotatably terminating in appropriate bearings. A pump impeller assembly removably mounted to each of the impeller shafts includes rigid, spaced-apart spiders having three, integral, radially spaced-apart outwardly extending arm segments. The spider arm segments support a pair of spiralled, spaced-apart mixing rods.

  • Patent number: 4436429
    Abstract: A slurry mixing and pumping system adapted to automatically control both slurry viscosity and product output volume. Water and raw gypsum delivered to a mixing vat are thoroughly blended by a hydraulically powered agitator blade within the vat. Hydraulic pressure variations experienced by the agitator motor are translated into pneumatic viscosity control signals by a process controller. An air actuated water valve driven by the controller varies water input into the vat to effectuate vicosity correction. Means responsive to vat head level controls output volume.

  • Patent number: 4318691
    Abstract: A high temperature furnace adapted to expand mineral ores such as vermiculite, perlite and the like. The furnace preferably includes an upright, vertically oriented frame adapted to support an elongated furnace tube into which mineral ore is delivered for expansion. Raw ore may be routed through a preheating system including a plurality of vertically spaced-apart, inclined baffles removably disposed within a preheating enclosure secured to the furnace. A preheater bypass system is included to facilitate use of the furnace with vermiculite. Flame control and mineral waste control are preferably effectuated with a flame guide adapted to be variably positioned intermediate a lower blast nozzle and a furnace tube heat input orifice. A plurality of thermal expansion couplings and supports are utilized to compensate for thermal expansion.
