Abstract: Process of refining of a metal bath in a crucible with oxygen blast at the top and crucible used. The invention consists essentially of providing in the bottom (15) of the crucible agitating gas injectors (15) located at least in a peripheral circular ring situated in immediate proximity to the refractory side wall. The injectors are preferably concentrated opposite the journals. Secondary injectors are, also preferably, provided in the bottom zone, intermediate between the ring and the center of the crucible. The invention makes it possible, in relation to the prior injection practice, to reduce the rate of dissolution of the agitating gas in the molten metal and then makes it possible to use a low-cost agitating gas, such as nitrogen, without risk of excessive nitridation of the bath.

Abstract: DRILLING METHOD AND APPARATUS            Abstract of the Disclosure -A drill having plural forwardly projecting circumfer-entially spaced cutting bits includes a hydraulic motor operated at full drilling fluid pressure to drive the cutting bits in unison through a first one-way clutch in a drilling mode.  A centrifugal device responding to higher speed rotation of the drill operates a reversing valve connected with the hydraulic motor to reverse it at required times to incrementally advance the cutting bits of the drill in unison to compensate for wear and present a new sharp cutting face on each bit for continued drilling.  The reversal of rotation of the bits is transmitted from the hydraulic motor through a second one-way clutch of the single revolution type which drives a pinion common to and in mesh with drive gears individual to the several cutting bits and matching the shapes of their flutes and being axially slidable relative thereto.  Locking rings individual to the drill bits and threadedly engaged therewith are coupled through paired clutch springs to the casing of the drill and to clutch sleeves individual to the bits and, in turn, fixed to their driving gears.

Abstract: Abstract A brake control arrangement permitting normal service brake actuation through a brake linkage and providing automatic brake actuation in case assisting fluid pressure decreases.  During normal operation, sufficient assisting fluid pressure is supplied to a pressurizable chamber to move an actuation piston to its nonactuation position against the biasing force of a spring.  When fluid pressure falls below the pressure needed to counteract the spring's biasing force, the spring displaces the piston to an actuation position relative to a surrounding housing and, during its displacement, displaces a brake engagement plunger to its brake engaged position.  Movement of the utilizing apparatus may thereafter be provided by axially displacing an engagement member against the actuation piston so as to drive the actuation piston to its nonactuation position.  The engagement member has an indentation which accepts displacement of the plunger thereinto and permits subsequent brake actuation by the brake linkage.

Abstract: ABSTRACT OF THE DISCLOSURE        Method and apparatus are provided for for performing immunoassays employing a device comprising a relatively small test zone referred to as an immunosorbing zone, and a rela-tively large liquid absorbing zone in liquid receiving relationship with said immunosorbing zone.  The immunosorbing zone includes a member of an immunological pair ("mip") -ligand and antiligand - bound to a support.         A signal producing system is employed in conjunc-tion with said device having as one component a signal label bound to a mip.  The signal producing system provides for production of a detectible signal in the immunosorbing zone in relation to the amount of analyte in a sample.         In performing the method, the immunosorbing zone is contacted with the sample in a solution which may include one or more members of the signal producing system.  The solution substantially uniformly diffuses through the immunosbosorbing zone resulting in concentration in the immunosorbing zone of the analyte and any members of the signal producing system present in the sample solution.  The immunosorbing zone may then be contacted with one or more solutions to wash away any non-specific binding signal label from the immunosorbing zone and to provide any additional members of the signal producing system to the immunosorbing one for development of the detectible signal in the immunosorbing zone.         The device provides that all fluids employed in the method pass through the immunosorbing zone into the liquid absorbing zone, which acts as a receptacle and driving force for drawing the fluid through the immunosorbing zone.  By appropriate choice of size, conformation and material of the liquid absorbing zone, the rate and amount of fluid which passes through the immunosorbing zone at each of the stages of the method can be controlled.  Thus, large volumes of liquid and large absolute amounts of reagents may be drawn through a narrow zone with the reagents at relatively low concentration as compared to the local concentration attained in the immunosorbing zone, while ensuring the sub-stantial absence of interference from non-specific binding of label and signal resulting from transient reagent.

Abstract: ABSTRACT OF THE INVENTION This invention relates to apparatus for producing formed shapes from dough.  In one embodiment, it comprises a cylindrical roll that is tangential to a linear apertured extruder plate which forms the egress passage from an associated dough extruder.  The roll has a surface depression which if unwrapped into a flat plane would have the desired circumferential shape of the product.  The depression is deeper at the leading edge passing said extruder plate as said roll rotates than at the trailing edge and the effect of this is that the extrusion pressure increases towards the rear of the extrusion thus compensating for the tendency of prior art extruded products to be narrower and thinner towards the rear.
