  • Patent number: 4463736
    Abstract: A fluid metering device is provided including a chambered rotor for metering correctly proportioned mixtures of air and a vaporized fuel to an internal combustion engine. The rotor includes radially disposed chambers and is enclosed in a housing having an inlet port and an outlet port. Upon rotation of the rotor the chambers are alternately biased into flow communication with the inlet port and the outlet port. The inlet port is in flow communication with a gaseous fuel supply and the outlet is in flow communication with an intake to the internal combustion engine. The speed of the rotation of the rotor is adjustable to vary the amount of gaseous fuel presented to the engine for selectively varying the output of the engine.

  • Patent number: 4459147
    Abstract: An adjusting mechanism is disclosed for the press head of a glassware forming machine of the rotating table type having a plurality of forming units circumferentially spaced for rotation about the axis of the machine. Adjustment is effected by rotating a parallel adjusting rod, which is engaged to a threaded rod. Rotation varies the pressure of the plunger by changing the position of a pinion on the threaded rod, through spring compression or pinion gear rotation, to which the stop lever on the plunger steam will contact. Each forming unit is capable of producing at least two glassware articles per machine cycle. A remote ram spring adjustment means provides operator control of ram spring pressure for each plunger at an accessable height and location.

  • Patent number: 4459135
    Abstract: Organic materials are separated and retrieved by mixing them with a liquid medium which is solid at room temperature and which is at atmosphere pressure. The material and medium are pumped by an electromagnetic pump while creating turbulence and then the velocity of the medium is decreased while heat is applied. Gases generated during the application of heat are collected. The medium is then cooled and returned to the pool at atmospheric pressure.

  • Patent number: 4452689
    Abstract: Greater product yield and quality as well as simplified gas recovery can be attained by a huff and puff process for retorting oil shale. The process can be advantageously carried out in in situ retorts under ground as well as in surface retorts above ground. In the process, an active retort of raw oil shale is retorted without prior combustion of oil shale therein with retort off gases, which have been heated in a spent shale retort. In the preferred mode, retort off gases from the active retort and air are alternately injected into the spent retort to cyclically heat the off gases and combust the coked shale. The retort off gases can be deoiled and optionally scrubbed of carbon dioxide and hydrogen sulfide before being heated in the spent retort.

  • Patent number: 4452611
    Abstract: A downdraft channel gasifier for the efficient conversion of biomass materials to usable heat energy, which includes at least two generally triangularly shaped air ducts positioned longitudinally across an enclosed housing defining a combustion chamber. The air ducts have sloping sides which downwardly converge towards one another to define at least one open-botton V-shaped channel, the sloping sides primarily supporting the biomass fuel which will be combusted to derive producer gas. The air ducts are hollow and are in fluid communication with a high pressure air source at one end, and with the gasification chamber through air jet openings near their apexes. The high pressure air exits out air jet openings along the top edges of the air ducts, providing primary air for gasification of the biomass in the channels. The producer gas passes down between the channels and horizontally to an exit.

  • Patent number: 4451268
    Abstract: A multi-stage generator for generating dry acetylene gas from calcium carbide while leaving a residue of dry lime has a generator housing including a plurality of vertically spaced shelves, each shelf and its associated components providing a stage of the generator. Each shelf has an exit slot and a water spray zone circumferentially spaced therefrom. A deposit zone is formed intermediate the water spray zone and the exit slot. Stirring arms are rotatably mounted to cooperate with each shelf to sweep the calcium carbide mixture received in the deposit zone into the wetting zone and thereafter into the exit slot. The exit slot of each shelf is offset angularly relative to the exit slot of the preceeding shelf so that the calcium carbide mixture is swept about each shelf through a substantial angle prior to exiting to the next shelf.

  • Patent number: 4449996
    Abstract: This application relates to parallel blank mold opening mechanism wherein the split blank molds, of which there are a plurality, are carried in holders that are mounted on horizontal hinge pins adjacent the rear thereof. These hinge pins are carried at the upper end of crank arms and move toward and away from each other during the cycle of operation of a pneumatic motor. Each of the mold holders is provided with a parallel link which is connected between the base of the mold mechanism housing and the holder, such that upon opening and closing of the mold the faces of the molds are maintained in a vertical plane. In addition, the position of the axes of the crank shafts and the hinge pins are such that the hinge pins move over top dead center or through the vertical plane defined by the axis of the crank shaft upon opening or closing. In this manner the molds are actually lifted a slight amount during movement from their closed to their open position.

  • Patent number: 4444598
    Abstract: A method for washing a U-shaped reaction tube having a thick cup portion and a thin non-cup portion is disclosed. At a first washing position, a washing liquid is supplied into the cup portion of reaction tube like a shower and is simultaneously sucked via the non-cup portion of reaction tube. Then, the washing liquid is supplied again into the reaction tube to fill the tube therewith at a second washing position. Finally, at a third washing position, the washing liquid contained in the reaction tube is drained at such a relatively slow rate that the liquid level of the washing liquid descends slowly. Any drop of the washing liquid is not remained on the inner wall of test tube, and thus it is possible to effect a highly accurate analysis without being affected by contamination between sample solutions.
