  • Patent number: 5236211
    Abstract: A pivoting drive system for the application of rectilinear drive force, wherein the rectilinear force is converted to a rotational force. The apparatus employs a frame on which are mounted pedals for rectilinear motion. The pedals are linked with a cable linkage and when moved along rectilinear paths cause the cable linkage to move. The cable linkage is wrapped several times around dual wrap spools which turn as the cable linkage is moved. A unidirectional clutching mechanism incorporated with the wrap spools causes a pivot axis to rotate unidirectionally on rotation of the wrap spools. The pivot axis may be connected with a sprocket and drive chain assembly to provide propulsion force, for example, to a bicycle wheel.

  • Patent number: 4842778
    Abstract: Process tower vapor/liquid flow distributor and packing bed comprising a plurality of relatively thin corrugated layers stacked one atop the other. The corrugated sheets are disposed in face to face contact with respective corrugations inclined to the horizontal and facing one another for the countercurrent passage of vapor and liquid therethrough. At least two layers are utilized and rotationally offset for diverting the vapor liquid in two separate directions to effect maximum vapor liquid distribution for countercurrent fluid flow passing therethrough. An improved homogenous mixture of vapor/liquid within the process tower packing sections may thus be provided. The assembly affords optimal pressure drop characteristic while maximizing even vapor/liquid distribution into the packing regions.

  • Patent number: 4832552
    Abstract: The power drive system of the present invention provides a rotary drive swivel unit which can be tilted along its horizontal pivotal axis until its output shaft is substantially horizontal. A drill pipe provided in a substantially horizontal bed adjacent to the drilling rig is aligned with the output shaft of the rotary drive swivel unit and this joint is made up. The rotary drive swivel unit is raised and the suspended drill pipe reoriented to a vertical position and is aligned over the drill string and added thereto substantially at platform level. The power drive system turns the drill string and advances the drilling downhole. The rotary drive swivel unit disengages from the drill string and the foregoing steps are repeated.

  • Patent number: 4776780
    Abstract: A shatterproof windshield repair device comprising a housing and a diaphragm. Under vacuum, air passages between the diaphragm and the glass surface form part of a first enclosure which can be evacuated and thus the device is held in place around conical cracks in the windshield. The vacuum in the first enclosure can be maintained by an assembly with a sealing capability. Surrounded by this first enclosure is a second enclosure which directly encircles the immediate area containing the conical cracks in the shatterproof windshield. A separate sealing lip, being part of the diaphragm, encircles this immediate area on the windshield and completely isolates the second enclosure from the first enclosure. In the center of the device is a cylindrical passage that axially extends from the exterior of the housing into the second enclosure. A piston assembly can move in and out of the cylindrical passage to introduce the repair liquid into the conical cracks in the shatterproof windshield.

  • Patent number: 4704804
    Abstract: Method of and apparatus for temperature conditioning of matter of the type wherein matter to be conditioned is exposed to a vapor within a vessel for select heating and/or moisture absorption or desiccation. The system includes selectively providing a mixture of condensible and noncondensible gases while controlling the enthalpy, partial pressure and dew point thereof. The gas mixture is delivered to a vessel and interacted with matter disposed therein. The temperature of the matter is brought to the approximate dew point of the condensible and noncondensible gas mixture. In this manner, both the ultimate temperature and moisture content of the matter to be conditioned may be controlled by selectively controlling the aforesaid parameters of enthalpy, partial pressure and dew point. Control of the aforesaid parameters may likewise be affected by controlling the vessel pressure and the rate at which energy is supplied to the condensible and noncondensible gas mixture.

  • Patent number: 4677841
    Abstract: Gas is vented through a very small orifice or pore with substantially stable pressures before and after the orifice. The orifice is designed so that the expansion through it is similar to a Joule-Thompson expansion of the gas. With ideal gas, this occurs isothermally. The flow through this orifice is determined for a selected pressure drop across it and the square of this flow is inversely proportional to the relative density. With real gases there is a slight error introduced due to a supercompressibility of the gas, but this is offset by an error in the opposite direction believed to be due to the Joule-Thompson cooling of the gas as it passes through the orifice. Substantially exact error cancellation is obtained within a preferred operating range of the pressure drop across the orifice for a given orifice diameter.

  • Patent number: 4667418
    Abstract: An anaerobic, pasteurizing conditioning system for treating matter such as whole and ground grain and minerals to increase the rate of conversion during digestion and thus the nutritional value thereof. The system comprises a direct fired steam generator adapted for producing treatment fluid comprising steam and non-condensible gases the gases containing insufficient oxygen for substantial aerobic bacterial growth. The steam and oxygen deficient non-condensible gases are discharged into the vessel for counter-current flow relative to matter passing therethrough. The operation of the direct fired steam generator is controlled for producing a sufficiently large volume of oxygen deficient gases and steam for purging the matter of other gases flowing therewith and maintaining the deficient oxygen level in the non-condensible gases for creating an anaerobic condition.

  • Patent number: 4655852
    Abstract: A steel article which is made of carbon or low alloy steel, with a prescribed chemical composition, is heat treated so that its yield strength is increased to a minimum of 60,000 psi and is subsequently dipped or spray covered with aluminum and then heated to interdiffuse aluminum metal and the iron in the steel matrix, thereby forming a new intermetallic layer which is an integral part of the steel article and which is essentially an aluminum-iron alloy, all in a manner which does not lower the yield strength of the steel below 60,000 psi. In the preferred form of the invention, a steel article is austenitized above its critical temperature for about 15 minutes or more and is subsequently rapidly cooled to below F. to transform the austenite structure to a much stronger martensitic structure and is then reheated to below F. to temper the martensite.
