  • Process for testing the carcinogenicity of a material or the presence of cancer-inducing factors in an environment
    Patent number: 4871661
    Abstract: Materials can be screened for carcinogenic properties by administering them to test animals and assaying biological tissue, preferably plasma, for the presence of a 60K cancer-associated phosphoprotein. The test is applicable to a wide range of chemically-diverse carcinogens and is not restricted to carcinogens having one particular mode of action.

  • Compressor
    Patent number: 4869641
    Abstract: A compressor driven by a motor delivers air under pressure to a plurality of paint spray guns. An air circulation fan is incorporated with the motor to cool the apparatus during operation. The compressor shaft includes bearings on each end and the bearing on the lower end is physically separated from the lower end of the compressor to prevent oil contamination of the air being discharged. A pump is associated with the separated bearing which delivers oil to lubricate the bearing when the compressor is in operation.

  • Antigenic modification of polypeptides
    Patent number: 4855285
    Abstract: Endogenous and exogenous proteins, and fragments thereof, are chemically modified outside the body of an animal so that when injected into the animal they produce more antibodies against the unmodified protein than would injection of the unmodified protein or fragment alone. The chemical modification may be accomplished by attaching the proteins or fragments to carriers such as, for example, bacterial toxoids. The chemical modification can also be accomplished by polymerization of protein fragments. Proteins which can be modified include Follicle Stimulating Hormone and Human Chorionic Gonadotropin. The modified polypeptides may be administered to animals for the purpose of contraception, abortion or treatment of hormone-related disease states and disease disorders, treatment of hormone-associated carcinomas, and to boost the animals resistance to exogenous proteins, for example viral proteins.

  • Method and apparatus for continuous casting of molten metal
    Patent number: 4819712
    Abstract: Metal strip may be cast directly from molten metal in an open tundish onto a chill roll. Strip thickness is controlled by contouring the tundish lip with an offset near the casting wheel. This can be used remedially to offset the natural tendency for the strip to be thicker near the edges, which is undesirable for cold rolling, or it may be used creatively to produce contoured strip.

  • Method of locating hydrocarbon producing strata and the instrument therefor
    Patent number: 4805450
    Abstract: A cylinder is mounted to descend a borehole for purposes of measuring the mass flow rate of gas flowing upward in the borehole. Within the cylinder is a source of tracer gas which is ejected at a constant mass flow rate [05] from near the lower end of the cylinder. A tracer gas concentration measuring means near the top of the cylinder will measure the degree of concentration of the tracer gas and thereby provide a measurement of the mass flow rate of other gases flowing upwardly around the cylinder.

  • Bag-in-box packaging and dispensing of substances which will not readily flow by gravity
    Patent number: 4796788
    Abstract: Bag-in-box packaging of products which will not readily flow under gravity conditions for discharge. The bag is of special three-ply form to provide separate product and pressure chambers. Coupling fitments are connected independently to the respective chambers. When it is desired to dispense the product, the product fitment is exposed at a wall of the box along with the pressure fitment. A dispensing valve on the product fitment is opened and pressure is supplied and maintained in the pressure chamber to expand it and exert pressure through the baffle wall on the product in the product chamber to aid in the dispensing of the product therefrom. Before applying dispensing pressure, the box is disposed in an enveloping pressure-resisting unit. A novel method is provided for efficiently producing the special bag.

  • Aluminum flake mulch
    Patent number: 4794726
    Abstract: The invention comprises a mulch sheet to be placed on the soil around the stalk of a plant. The mulch comprises aluminum flakes bonded to a woven mesh which aluminum flakes will reflect rays of the sun upward to the underside of the leaves and the mat will hold moisture in the ground which has seeped into the ground through the porous mat. The aluminum flakes are applied to the upper tacky surface of a thermoplastic woven mat and are pressed into the tacky surface to hold them in position after the thermoplastic, fibrous mat cools to freeze the flake in place. In additional embodiments, it is sometimes appropriate to make a pod containing a seed which will be secured to the underside of the matting in the open hole. A layer on the underside of the mat could include a layer of fertilizer.

  • Pump
    Patent number: 4773832
    Abstract: An improved diaphragm pump in which the diaphragm has a majority of its area available for flexure and deformation thereby allowing for a variable stroke length on the diaphragm pump and decreased wear of the diaphragm in operation. Additionally such a flexible diaphragm is additionally deformed by the pressure of the fluid in the pumping chamber thereby forming a "piston" of the diaphragm as it is deformed over the deforming piston of the pump.

    Patent number: 4773695
    Abstract: A windshield attachment for a golf cart or the like comprising an upper panel hinged to a lower panel at a horizontal hinge for movement from upright closed position to a lower dependent open position. The lower panel is provided with vertically spaced crossbars of tubular type with slotted ends. Clamping units fit over the posts and extend into the crossbar slots in interlocking relationship with the bars to hold them in selected horizontal positions at the respective levels.

  • Apparatus for injecting gas into a pipeline
    Patent number: 4773255
    Abstract: The invention provides a method for tagging methane by adding thereto one or more of the tracer compounds sulfur hexafluoride and chloropentafluoroethane. The methane being tagged is normally being stored in underground storage fields to provide identity and proof of ownership of the gas. The two tracer compounds are readily detectable at very low concentrations by electron capture gas chromatography apparatus which can be made portable and thus suitable for use in the field.

  • Roof drilling system
    Patent number: 4773490
    Abstract: A roof-drilling system for use in subterranean mining applications and the like in which the drill head of a roof drilling machine is arranged such that the receiving cavity of its chuck is configured having a lost motion association with the drive-in portion of starter and driver drill steel rods. The lower surface of a retainer fixed to the drill head and having a non-circular aperture formed therein serves to define one bearing surface for utilizing the drill head itself to pull the assemblage of drill steel from a completed bore. To remove the drill steel driver component from the drill head chuck, the miner grasps the lowermost portion and rotates it a relatively small amount. To provide for interlocking of various components of the drill steel, i.e.
