Abstract: ABSTRACT OF THE DISCLOSURE       Method and apparatus for forming shaped meat products capable of withstanding subsequent cooking without loss of geometric integrity.  Chunks of uncooked animal meat, after mechanical working to cause a tacky exudate to form on the surface of the meat, are packed in a closed mold structure and frozen to cause expansion of the meat within the closed mold.  Pressure developed entirely by expansion of freezing forces the meat chunks to fill any voids within the mold and to press the meat chunks tightly together to form an integral block or loaf of meat conforming to the shape of the mold.  To control the pressure within the mold, a portion of the mold is closed by a resiliently biased member capable of resisting movement of the member in response to internal pressures up to a predetermined range which are generated by expansion of the meat.  When removed from the mold the meat may be cut and prepared in any desired conventional manner without loss of its geometric integrity.

Title: Low smoke density fire-retardant unsaturated aliphatic polyester resins containing alumina hydrate
Inventor: MAKHLOUF JOSEPH M

Abstract: Abstract of the Disclosure Curable polyester resin compositions formed from unsaturated polycarboxylic acids and polyols and a crosslinking aliphatic vinyl monomer component being essentially free of aromaticity are disclosed.          The degree of unsaturation in the polyesters is carefully controlled so that the resin can be cured to produce strong thermoset products. Resins of this nature can be filled with high levels of aluminum hydrate to give compositions that have high oxygen indices and very low smoke densities as measured by the National Bureau of Standards Smoke Chamber. Also, when burned, the compositions of the invention emit non-toxic gases. Preferably, both the polyester and the vinyl monomer component are aliphatic, although a controlled amount of aromaticity can be present in the polyester portion.

Abstract: ABSTRACT OF THE DISCLOSURE             The deposition of an aromatic diazonium nitrate on the walls of a pipeline through which is conducted a residual gas produced in the diazotization of a primary aromatic mono-amine is prevented by heating the walls of the pipeline, limiting the residence time of the gas in the pipeline, or providing for the absence of nitrogen dioxide in the gas. Nitrogen dioxide can form in the pipeline when nitric oxide and molecular oxygen are present, but the deposition of the diazonium nitrate, formed from the nitrogen dioxide via a reaction with the monoamine, is prevented by the hot pipeline walls and/or short residence time.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic equalizer for calculating the equalization transfer function of a transmission channel and applying same to equalize received signals.  The initial calculation as well as the equalization proper are conducted entirely within the frequency domain.  Equalization coefficients are obtained using successive approximations approaching    the desired values.  The equalization coefficients may be adjusted independently from each other inasmuch as these coefficients are not interdependent.  Successive approxi-mations of the coefficients differ by fixed increments of the real or imaginary components.  A feedback circuit is utilized in generating the successive approximations wherein sign or polarity information is used to determine the adjustment necessary for convergence.

Abstract: ABSTRACT       The rotating backwash isolation hood of a multibed filter is raised and lowered by either hydraulic forces and gravity, or by an improved mechanism employing a pair of pistons and cylinders and a perforated indexing disc, or by both of these arrangements.  The force required to lift the hood is reduced by eliminating the effect of the static head of the liquid above the hood.  Leakage between the hood and the filter it covers is detected by a pressure differen-tial indicating switch.  A floculator may be combined with the multibed filter, and the dirty backwash liquid from the hood may be recirculated into the floculator.
