Abstract: ABSTRACT OF THE DISCLOSURE The invention refers to a process for the manufacture of mechanically and chemically stable, porous biocatalysts with high enzymatic activity by including whole cells, cell fragments, or enzymes in polymers, whereby mixture (A) is in-serted into mixture (B) as a precipitation bath.  Mixture (A) is composed of an enzymatically active substance in an aqueous solution or suspension and a water-soluble polyelectrolyte, or of an enzymatically active substance in an aqueous solution or suspension of an epoxyprepolymer component, a multifunctional harden-ing component and a water-soluble polyelectrolyte, and mixture (B) is composed of the aqueous solution of a compound containing polyvalent ions charged oppositely to the polyelectrolytes.  When stirred, the bead-like particles that have formed are solidified, washed, and following filtering off are carefully dried to contraction and solidification, and hardened, washed and discharged in the moist condition in mixture (B), or washed and discharged in the moist condition follow-ing solidification of the epoxy matrix in a phosphate buffer solution for dis-solving out the polyelectrolytes.

Abstract: ABSTRACT OF THE DISCLOSURE   Hauling and cutting equipment includes a conveyor trough having a longitudinal side wall on each side with a side with a support rail structure on at least one side having a chain guide groove therealong through which a endless link chain extends.  A cutting machine overlies the trough and is guided on the rail structure and includes a drive on one side with a sprocket or chain wheel which has teeth which engage in horizontally disposed links of the link chain. The space between the teeth accommodates the vertically disposed links of the chain.  The link chain comprises long horizontal links and short vertical links which are shorter than the horizontal links.  The pitch of the vertical links is at least double the link stock diameter of the horizontal links except for a small clearance for movement play.  The engagement division of the chain wheel is matched to the length of the vertical links.  This arrangement allows for horizontal and vertical flexure of the chain to permit the chain to follow curves and inclines of the conveyor without the links pushing into and pulling away from one another, which gives rise to problems of tooth stress in the sprocket or chain-wheel and possible mis-engagement between the teeth and the chain.

Abstract: ABSTRACT     A nonaqueous electrochemical cell and a method for the construction thereof wherein the cell contains a metal salt additive such as lithium nitrate (LiNO3) or calcium nitrate Ca(NO3)2 which reduces the reactivity of substantially the entire active cathode surface.  Electrolyte solvents such as propylene carbonate are thereby substantially prevented from reacting, on the surface of the cathode, with oxidizing agents within the cell. Decomposition of the electrolyte solvent with gaseous evolution is substan-tially reduced and cell stability is enhanced.  The metal salt additives are particularly useful in nonaqueous cells containing manganese dioxide cathodes.

Abstract: ABSTRACT A material transport system is disclosed which comprises, in combina-tion, means for effecting the controlled distribution of a particulate solid-liquid matrix, and means for urging the matrix by positive displacement through a constraining conduit so that no degradation of the particles of the matrix occurs during transit thereof.  The said particles are sufficiently closely packed to ensure the movement of the particles by plug flow wherein the liquid is displaced towards the periphery of the conduit to constitute wall-slip fluid, whereby shear forces within the plug are absent.  The means for urging the matrix is a pulse-free discharge positive displacement pump, the fluid sealing means for the pistons and valve plates thereof being also the source, at least in part, of the wall-slip fluid.  An auger or screw feed delivers said matrix to the suction side of said pump.  Water entry injectors feed the suction side of the pump with lubrication fluid.

Abstract: Abstract of the Disclosure A recursive automatic equalizer is described for implementing the telephone equalization function at a line circuit which may be multiplexed between a plurality of telephone subscriber sets.  A recursive digital filter structure having programmable coefficients minimizes the error between the equalizer input and a reference signal. The recursive filter transfer function is variable via feed-back coefficient update, with respect to its input and the reference signal.  The recursive filter coefficients are adaptively changed to rapidly converge to a final value based upon a mean square error algorithm.  The desired filter transfer function can be achieved with a low number of coefficients, for example, five, rather than the here-tofore high number of coefficients required in non-recursive filter structures.
