Abstract: S P E C I F I C A T I O N                 MATERIAL LAYER DIVERTING MEANS FOR A CROP MATERIAL ROLL FORMING MACHINE                 ABSTRACT OF THE DISCLOSURE      A roll forming machine picks up crop material and forms, twins wraps and discharges rolls or large round bales thereof as the machine is continuously moving across the field.  The machine has a mobile frame supporting a pickup and a floor, the latter supporting a lower conveyor. A rear upper apron is movably supported on the frame above a rear portion of the lower conveyor and floor and defines a rear roll forming region therewith.  A front upper apron is movably supported on the frame above a front portion of the lower conveyor and floor and defines a front roll forming region therewith having an inlet end and a discharge end.  The front upper apron has a portion located at the discharge end of the region which is disposable in closely spaced relationship above the conveyor means and floor.  The lower conveyor is operable to move crop material along one path from the inlet toward the discharge end of the roll forming region, while the front upper apron is movably operable to move crop material along another path generally upwardly away from the discharge end of the roll forming region.  Two embodiments of means are disclosed which are movable with the upper apron and have portions which extend outwardly therefrom and into the space between the apron and lower conveyor at the discharge end of the region and are thereby effective to divert crop material upon its arrival at the discharge and of the region out of the conveyor path and into the apron path away from the discharge end.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous automatic calibration system and fault detection method for analytical instruments of the kind used for measuring constituents of a fluid sample which system includes a memory for storing reference information, a comparator circuit for continuously comparing the instrument output to the stored refer-ence information, and a sample-and-hold circuit charged positive or negative by the comparator, depending whether or not the instrument output exceeds the value of the reference information.          The output of the sample-and-hold circuit in turn is coupled to the instrument continuously to adjust its output to correct value.          Where the maximum allowed corrective range of the sample-and-hold circuit is exceeded by the signal from the comparator circuit beyond a predetermined time period, the system displays fault, warning the operator.

Abstract: ABSTRACT OF THE DISCLOSURE A method of attaching a sintered friction material to a steel reinforcing cup.  The sintered friction material is loosely placed in the steel reinforcing cup.  an electrical induction heater surrounds the reinforcing cup and rapidly raises the temperature of the reinforcing cup to a predetermined temperature.  When the predetermined temperature is reached, the reinforcing cup and sintered friction material are immediately moved to a press before the temperature of to bulk of the sintered friction material is significantly changed by thermal conduction of heat from the steel cup to the friction material.  A single compressive force is applied to the sintered friction material and the steel reinforcing cup to compact the sintered friction material and the steel reinforcing cup to compact the sintered friction material to a predetermined density and to form a metallurgical bond along the entire interface between the friction material and the reinforcing cup.

The thermostatic element is designed to be closed at operating temperatures.  The drain orifice in the other path is designed to continuously pass the condensate and the like which will form in the line when the system is at or near opera-ting temperatures while restricting the passage of working vapor.

Abstract: ABSTRACT:                The optical cross-talk in the target of a camera tube which comprises, for example, a target made of lead monoxide is reduced by an element which overlaps the entire target. If this element consists of a filter which is arranged in front of the photo-sensitive layer, a spectral transmission which is adapted to the spectral sensitivity of the target is imparted thereto. A filter which is arranged behind the target is preferably con-structed so that it is also low-reflective for incoming light. In order to prevent excessive transverse conduction, the latter filter may have a mosaic structure consisting of mutually insulated areas. The element may alternatively be formed by a target support which is separa-tely arranged in the camera tube and which has a small thickness.

Abstract: ABSTRACT   The production of hydrogen by reacting a carbonaceous material with water and at least one halogen selected from the group consisting of chlorine, bromine and iodine to form reaction products including carbon dioxide and a corresponding hydrogen halide.  The hydrogen halide is decomposed to separately release the hydrogen and the halogen.  The halogen is recovered for reaction with additional carbonaceous materials and water, and the hydrogen is recovered as a salable product.  In a preferred embodiment the carbonaceous material, water and halogen are reacted at an elevated temperature.  In accordance with another embodiment, a continuous method for the production of hydrogen is provided wherein the carbonaceous material, water and at least one selected halogen are reacted in one zone, and the hydrogen halide produced from the reaction is decomposed in a second zone, preferably by electrolytic decomposition, to release the hydrogen for recovery and the halogen for recycle to the first zone.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus are described for reducing or removing the background noise caused by thoron gas (220Rn) in uranium exploration conducted by the detection of radon gas (222Rn) emanating from the ground.          This is accomplished by the use of a number of alpha particle detectors, each of which is disposed in a protective enclosure.  A barrier which permits, but deliberately retards, the passage therethrough of gases is disposed in the path to be traversed before such gases can reach the alpha particle detector.  The increase in the transit time made necessary by requiring soil gases to move through the barrier should be sufficiently long to allow the decay of most of the thoron, thereby eliminating its contribution to the total signal reflected by the dectector.
