  • Patent number: 4139046
    Abstract: A method is presented to make an investment casting pattern of a rotatable turbine wheel or a stationary turbine nozzle wheel having one continuous and regular series of blades extending around its periphery with a uniform pitch between blades and in which all such blades are bent in one circumferential direction and adjacent blades overlap each other in a circumferential direction so that the wheel pattern cannot be made in a simple two part mold separating at right angles to a parting line. The method comprises separately forming two wheel pattern portions of the same diameter as the finished turbine wheel pattern, each having a series of continuous and regular blades around its periphery with a uniform pitch between the blades which is exactly twice the pitch of the blades in the finished wheel pattern. In such a pattern wheel portion the adjacent blades do not overlap each other.

  • Patent number: 4131543
    Abstract: This invention presents a preparation of expanded silicate-based aggregates as useful in a method for absorbing hazardous liquid materials. This expanded silicate-based aggregate material has previously been known for use as insulation, fireproof wallboard and insulating blocks, high temperature pipe covering, fire proofing of steel structures, marine deck filler and for cement block in non-bearing fire walls, but not for absorbing hazardous liquids. The present invention uses this aggregate material, either alone or mixed with a solution of five to seven percent of polyvinyl chloride in a solvent comprising 15% dimethylsulfoxide and 85% methylethyl ketone providing a paste which may be placed on a hazardous liquid material and within seconds will absorb the hazardous material throughout the thick paste material.

  • Patent number: 4129385
    Abstract: A photoacoustic cell for analyzing solid and quasi-solid samples and which includes a table for holding a sample to be analyzed and which is movably disposed in the cell housing and positioned in a sample test position to form a part of the cell chamber in which the sample is to be analyzed or tested. The cell chamber is formed having a window through which a light source may pass onto the sample whereby energy is released inside said cell chamber characteristic of the light source and is sufficient to provide a signal characteristic of the absorbance of the sample and which is sensed by a microphone in said chamber. At the completion of the sample test, the table may be moved to a sample load/unload position for discharge of the tested sample and preparatory to having a subsequent sample placed thereon for analysis.

  • Patent number: 4128479
    Abstract: A unit is presented for the transfer of a gaseous component in one stream to or from a liquid component in another stream, in which a membrane assembly is wound spirally around a central rigid cylindrical core. The membrane assembly comprises a continuous length of flattened tubular membrane with a gas net passing through the intermediate portion of the membrane from end to end thereof and substantially the width of the interior of the tubular membrane. In forming the coil, a net separator is wound between the membrane layers of the coil. An inlet tube for one of the components communicates with one end of the membrane and an outlet tube for the same component communicates with the other end of the membrane. Means is provided for passing another of the components longitudinally of the coil between the membrane layers from one end of the coil to the other end. The specific embodiment of a blood oxygenator is described.

  • Patent number: 4128160
    Abstract: A vertical joint structure is shown extending longitudinally of a generally cylindrical housing encasing a screw conveyor for a breading machine or the like. The housing comprises two generally C-shape half portions formed of sheet metal and assembled by means of a novel joint structure along two longitudinal zones diametrically opposite in the housing. One half portion is fixed in the machine and the other half portion is movable toward and away from a tight fit of the joint structure with the fixed half portion. The distal edges of the movable C-shape half portion extend a short distance beyond a diameter of the housing at approximately a right angle to that diameter and are there bent downwardly and outwardly at an acute angle to a zone just at, or a little beyond, that diameter and there bent outwardly approximately radially of the cylindrical housing. This forms a first linear sealing surface at the acute angle portion.

  • Patent number: 4121124
    Abstract: An electrodynamic force generator or vibrator employing plural ring permanent magnets and a round magnetic structure of the center gap type that is split on a horizontal plane passing through the center and a support and guidance system for supporting the vibratory table and coil consisting of a plurality of horizontal damped cantilever springs joined to "C" shaped damped compensating springs. Typically, a round drive coil of plural turns surrounds a central core or pole of the magnetic structure and is influenced by flux on all sides. Shorted turn coils surround the drive coil and are stationary upon the outer pole to provide reduction of inductance. The drive coil is attached to a table structure which is supported and guided in the magnet structure.

  • Patent number: 4111212
    Abstract: A method and apparatus for dosing and weighing "shag" tobacco comprising the steps of dosing an approximate quantity of tangled long fibre tobacco, which is less than the required quantity, and subsequently dosing disentangled long fibres to make up the approximate quantity to the required quantity of long fibres. Thus the quantity of short fibre tobacco added thereto to obtain the quantity nominally required per package can every time be equal.

  • Patent number: 4109040
    Abstract: A cushioning dunnage product produceable from a mechanism which is of relatively compact nature utilizing a roll of sheet-like stock material, such as paper. As the stock is pulled off the roll, the edges are rolled inwardly in a longitudinally convergent chute, into generally superimposed condition. Pusher means urges the sheet-like stock material laterally toward a confronting surface of the chute. Then the inwardly rolled stock is passed into a crumpler section where mechanism attach together the confronting portions of the rolled edges of the stock material generally centrally, in a direction lengthwise thereof, to retain the dunnage product in highly compressible, lightweight pad-like form. A transfer vehicle is adapted to coact with the dunnage producing mechanism for storing a preselected amount of the pad-like dunnage product on the vehicle, whereupon the vehicle can be moved to a location distant from the dunnage producing mechanism for use at the distant location.

  • Patent number: 4094146
    Abstract: A solar engine including an air motor driven by a quantity of pressurized hot air from a solar heater vessel and including an air pump for pumping substantially an equal mass of cool air back into the solar heater. The driving action of the air motor and simultaneous pumping action of the pump is accomplished in one embodiment by means of a moving piston which separates the driving and pumping sides of the air motor enclosure, whereby substantially both displaced volumes are substantially equal. Air is used as both the heat transfer means and as the actual working fluid. The engine provides for an unlimited life for the solar collector, and an engine of relatively low friction and substantial simplicity.
