Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for indicating the farthest advance position of a bi-directionally movable medium is provided with a pulse generator mechanically coupled to the medium to generate pulses corresponding to incremental movements of the medium in either a first or second direction. The actual direction in which the medium moves is represented by respective first and second signals. A counter incrementally changes its count in response to each gen-erated pulse when the medium moves in, for example, the second direction, and the counter reverses the direction in which it counts when the medium moves in the first direction following medium movement in the second direction so that the counter incre-mentally is restored to an initial count. Once the initial count of the counter is restored, an output farthest advance signal is produced indicating that the medium has reached its farthest advance position. In one embodiment, the apparatus is used to indicate the farthest advance of a movable web. When the web is reversed, the counter is decremented from an initial predetermined count. When the web subsequently is moved forward, the counter then is incre-mented. Once the web reaches the farthest advance position previ-ously occupied prior to reverse movement thereof, the counter con-currently reaches its initial, predetermined count.

Abstract: ABSTRACT OF THE DISCLOSURE        Brazing of aluminum is preformed by the employment of a flux comprising a mixture of non-hygroscopic potassium fluoaluminates, essentially free from unreacted potassium fluoride.  The flux is preferably produced by fusing together commercial grades of potassium fluoride and aluminum fluoride. The flux may advantageously be employed in the form of an aqueous slurry. The advantage of the method is that the flux is totally water-insoluble and may be stored in the form of a slurry without risk of disproportionation. Furthermore it leaves no soluble residues after brazing.

Abstract: ABSTRACT         A pneumatic ejector device suitable for use in an aerial bomb ejection system, in which pivotably operable jaws for gripping the bomb or other device are operatively interconnected to a pneumatically operated piston which engages with the bomb to effect positive release.  The piston is contained within a gas tight cylinder and a radial clearance is pro-vided therebetween to allow for gas leakage to both sides of the piston. The piston is locked in the loaded position by means of a spring and ball detent and is "armed" by charging air or other gas under pressure into the cylinder.  Ejection is achieved by releasing gas pressure from the lower side of the piston at a rate in excess of the rate of leakage past the piston, by means of a solenoid controlled release valve.

Abstract: Case No. 5751 Process for Making Methanol Abstract of the Disclosure A process for producing methanol from air-blown gasified coal.  A feed gas stream obtained by the coal gasification step is combined with a recycle gas stream and fed to a reactor where carbon oxides are converted to methanol.  Exit gas from the reactor is scrubbed to remove carbon monoxide, and the carbon monoxide-free exit gas is then chilled to remove all components except hy-drogen,  The hydrogen is then combined with the carbon monoxide and used as a recycle stream.  The process enables use of an air-blown gasified coal stream while maintaining the nitrogen content in the reactor at an acceptably low level.

Abstract: CRUD HANDLING CIRCUIT             Abstract of the Disclosure A method for handling the problem of crud formation in the solvent extraction of wet-process phosphoric acid is described.           Crud is the name ordinarily given to the thick interfacial layer of semi-floatable material which tends to form and accumulate, and which interferes with many of the extraction processes and, in particular, with the solvent extraction of wet-process phosphoric acid.  The method described provides for the operation of the solvent extraction stages in a manner that allows the formation and temporary accumulation of crud in those stages whereupon the solvent and the crud are then removed from the extraction stages and treated in a series of operations which include a clarification step, an acid removal step, a water wash step and a caustic treat-ment step, which steps effectively separate the solvent from the crud, and remove the crud components from the system and regenerate otherwise unusable solvent.        The invention is particularly applicable to the solvent extraction of wet-process phosphoric acid for the recovery of uranium by the reductive stripping technique.

Abstract: ABSTRACT OF THE DISCLOSURE         A supply pump comprising a body having an inlet and an outlet both in fluid communication with an interior region of the body which contains two pistons positioned to reciprocate coaxially and which define three variable volume chambers, one between the two pistons and in fluid communication with the inlet, a second between one piston and the outlet and a third between the other piston and the outlet.  The pistons have different working areas, and the piston of larger area carries a check valve which allows fluid flow from the chamber between the pistons to the chamber between the larger piston and the outlet.  A regulating spring acts between the body and the smaller piston to urge both pistons against a mechanical drive means including a reciprocable rod carried by a tappet contacting a driven cam.  During each forward and reverse stroke of the pistons in response to rotation of the cam, supply fluid is drawn into the pump through the inlet and forced out of the pump through the outlet.

Abstract: CENTRIFUGAL PUMP WITH SINGLE BLADE IMPELLER                        Abstract A centrifugal pump which has a single-blade impeller and is used particularly for the transport of long-fibered deposited solids, for example, in sewage.          The pump impeller discharge end lies in a radial plane adjacent a housing wall there being a clearance between the housing wall and the discharge end.  The blade face is directed to the housing wall to form an acute angle with that wall, the line between the outer extremity of the blade and the discharge end of the blade forms    an acute angle relative to the axial direction of the impeller.  The front edge of the impeller is sharpened and provides a moving shearing edge, and the housing wall provides a stationary shearing edge so that medium pumped into the impeller can be cut and disintegrated between these edges.  The angles defined facilitate drawing the long-fibered solids into the area for shearing and disintegration.
