In a device for toppling articles of at least approximately rectangular outline while conveying such articles, which device includes a discharge path provided with carrier elements for moving the articles after toppling in a discharge direction lying in the plane of their outlines, at least two input paths are provided above the discharge path for conveying such articles in an input direction transverse to the discharge direction, with the plane of the outline of each article perpendicular to th...

An improved valving system is provided in a dialysis system in which the dialysis solution flow path through the dialyzer may be sealed off adjacent the inlet and outlet of the dialyzer, with the pumped dialysis solution being shunted so that the pump and heater do not need to be turned off. As ultrafiltration takes place over a predetermined period of time, it can be directly measured by monitoring the liquid level of a reservoir connected to the sealed portion of the dialysis solution flow pat...

Spraying of coal in an open top hopper car with an aqueous composition containing at least about 2.5% of a binder material consisting of solid material in an aqueous suspension of an asphalt emulsion or a black liquor lignin product and containing 0.1 to 2.0% of water soluble ethoxylated alkyl phenol or sulfo succinate wetting agent results in the formation of a crust layer which provides protection against loss of coal due to wind action during rapid movement of the car.

The invention provides a novel process for the removal of fluorine during the production of fertilizer by precipitating the ion during the ammoniation step and recovering same by pyrolysis. To recover the fluorine the fertilizer is first separated out as a filtrate and the precipitate is heated to evolve ammonium fluoride, which heating is done in an ammonia atmosphere.

Deceleration control apparatus for an aircraft having an automatic altitude capture and hold system and an airspeed hold system, both systems controlled by controlling pitch attitude wherein during a descent from a higher altitude under airspeed-on-pitch control with throttle set at idle thrust, and at some existing negative altitude rate, a slower speed is commanded, a synthetic altitude based on the existing descent rate is computed and the attitude capture and hold system operation is switche...

The apparatus comprises a zero pass detector (2) for detecting zero passes in a voltage signal proportional to the line current to generate a pulse signal constituted by positive and negative rectangular pulses of equal amplitude and of width dependant on the duty ratio of the line signal, a pulse signal processor constituted by a saturable integrator circuit (4) connected to integrate the pulse signal and to deliver a triangular signal having a positive peak value which increases after ringing ...

The method of treatment during transport of solid waste by depositing the solid waste on the surface of a molten stream of lead traveling in one direction whereby organic material in the waste is subjected to thermal degradation, metals and other materials in the waste which are insoluble in the molten lead and of lesser specific gravity remain on the surface of the molten lead for removal and recovery while metals and other materials which are soluble in the molten lead dissolve in the molten l...

A method of machining pipe at high speeds is disclosed that includes the steps of moving the pipe from a pipe rack onto a conveyor, moving the pipe longitudinally into the chuck of a threading machine or the like, clamping the pipe in the chuck, transferring the pipe from the conveyor to one or more steady rests, and supporting the steady rests on flexible wall air cylinders that will allow the steady rest to move as required to support the pipe which, because it is not straight, will whip and m...

A drop device, method and article of manufacture used in measuring lagtime in the drilling of a well. A unique container with calcium carbide is inserted upwardly by its guide end into the open end of a pin connection prior to its threaded assembly into a lower box connection on drill pipe. The container is handled by a resilient member during placement into the pin connection and secured in place by a loop on the resilient member. The container is formed in a right cone of thin sheet material a...

Radioiodination of aminoacyl-transfer RNAs with either .sup.125 I or .sup.131 I resulted in the preferential addition of radioiodine to bound tyrosine. The radioiodinated tyrosyl-tRNA was 10-fold purified by chromatography and was found to consist essentially of monoiodo- and diiodo-tRNA in approximately equal isotopic proportions. The radioiodinated tyrosine was readily incorporated into proteins synthesized in broken cell reactions. The specific activity of the iodine-labeled proteins can be m...
