Abstract: METHOD AND APPARATUS FOR GENERATING         A HOT AIR BLAST     ABSTRACT OF THE DISCLOSURE          A system to supply high temperature blast air and a method for providing preheating of a cold air blast by gas-to-air heating in a tube-type heat exchanger with heat from waste products of combustion.  Such combustion products are recovered in a header by the use of valves at different times to form a continuous supply from a plurality of horizontal regenerators.  The regenerators are horizontal metal vessels wherein a mid-portion is filled with checker-brick forming horizontal flow spaces.  Each regenerator has a burner to generate hot products of combustion for heating the refractory of the checkerbrick and recovery by the header.          The burner is turned OFF when the checkerbricks are highly heated and preheated air is directed by valves through a header and into the regenerator by the checkerbricks.  The resulting hot air blast, which may be tempered with cold air, is fed by a main to a blast furnace.

Abstract: ABSTRACT       Method and Apparatus for Regulating Fluid Flows in Parallel-Connected Conduits (e.g. in Furnace Installations having Air Preheaters and By-pass Conduits) Fluid flow in parallel-connected conduits is regulated by sensing the pressures and/or temperatures at the junctions of the conduits, and regulating the supply of power to a fluid propelling means operable in one of the conduits in accordance with a signal with is representative of the sensed pressure drop and/or temperature drop between the junctions. In a furnace installation having an air preheater (14) in a duct (12) and a parallel-connected by-pass duct (18), the pressure difference and/or temperature difference between the junctions (19,20) of the ducts (12,18) is/are employed to generated a signal which regulates the supply of power to an induced draft fan (17) in the air preheater duct (12).  The damper (21) normally provided in the by-pass duct (18) may be removed or set at its open position.

Abstract: Abstract of the Disclosure An improved lateral convergence deflection system for a delta-gun shadow mask color CRT includes first, second and third lateral convergence coils mounted on the CRT neck radially outward from the paths of the electron  beams  from  the three  guns.  The coils  are connected in series electrically,  and are of suitable strength  and orientation  to provide  a  substantially unidirectional,  vertical  field  in  the  path  of  one (e.g., the blue) beam, and field nulls in the paths of the  other  two  (e.g.  the  red  and  green beams).  By varying  the  current  passed  through  the  coil  by  a convergence  drive  amplifier,  the  blue  beam  may  be shifted  laterally  without  producing  any  substantial movement of the other two beams.

Abstract: HYDRAULICALLY ACTUATED CARDIAC PROSTHESIS            ABSTRACT A cardiac prosthesis having an hydraulically actuated compressible blood pump (RV). An actuation chamber (116) adjacent the blood pump (RV) receives pulses of hydraulic actuation fluid from an actuator pump (120) through a fluid inlet path (126) to compress the blood pump (RV) during systole and eject blood therefrom. Between pulses the actuation fluid is permitted to drain from the actuation chamber (116) through an outlet path (132) into a reservoir (12). Discharge of fluid through the outlet path (132) is controlled by a dump valve (130) which is adapted to close or open the outlet path (132) primarily in response to forces which vary as a function of the flow of actuation fluid through the fluid inlet path (126).

Abstract: ABSTRACT: Methods of manufacturing a dispenser cathode and dispenser cathode manufactured according to these methods.          When during the manufacture of a dispenser cathode a cathode body is first manufactured which comprises scandium oxide, and the emissive material is subsequently provided in the cathode, it is possible to obtain a larger scandium oxide concentration in the cathode surface. This results in a longer life and smaller sensitivity to ion bombardment of the cathode compared with the scandium oxide-containing cathodes known so far.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for deposition of coatings upon sub-strates generates a non-local thermal equilibrium arc plasma at the relatively high pressure of at least approximately 1 atmosphere.  A closed chamber is defined by a cylindrical anode and annular housings carrying transparent end plates.          A pencil-shaped cathode is passed through. one of the end plates coaxially into the chamber so that its tapered end is spatially proximate to an exit orifice centrally located in the anode.          Gas ports permit the introduction of a preselected gaseous environment at the desired pressure into the chamber.  A low-current arc is struck between the anode and the cathode estab-lishing the desired plasma.  Two coils are coaxially placed radially outward of both ends of the chamber in a Helmholtz coil configuration to generate a uniform magnetic filed in the chamber and induce rotation of the arc plasma.  The coating material is introduced into the plasma as by a reservoir in the cathode and its excited species ejected through the exit orifice in a plasma jet for deposition upon any substrate adjacent thereto.

Thereafter, the joint may be evacuated, whereupon further heating, quick compression and a certain holding time provide com-plete diffusion welding of the metal parts.  It is also suggested to reduce the cross section of the metal parts in the joint area and press these out to their original cross section during the diffusion welding.
