Title: Process for the production of a food material
Inventor: KIUCHI HIROSHI
IPC: A23L11/00
Filed: 1987-06-19
Granted: 1992-09-22
Abstract: Abstract This  invention  relates  to  a  process  for  the production of a food material from soybean milk.   Prior art food materials are generally produced by coagulation of  soybean  protein  which  results  in  poor  texture  and taste.   In this invention, soybean milk is treated with protease, at a pH in the range which does not result in acid coagulation and in the presence of a magnesium salt at  a  concentration  in  the  range  which  does  not  cause substantial  magnesium  coagulation,  to  flocculate  the protein in the soybean milk.  A food material having good texture and high processability is then obtained.

Abstract: TITLE              SURFACE BONDING OF CERAMIC BODIES                            APPLICANT               LANXIDE TECHNOLOGY COMPANY, LP                            INVENTOR              Stanley J. LUSZCZ, Marc S. NEWKIRK       Andrew W. URQUHART                           ABSTRACT     Ceramic bodies are bonded together via a layer of an oxidation reaction product of a molten metal, which metal is present in one or both of the ceramic bodies prior to bonding.  At least one of the ceramic bodies comprises a ceramic product formed by the oxidation reaction of molten parent metal (e.g., alumina from molten aluminum) and grown as molten metal is transported through, and oxidized on the surface of, its own oxidation product.  One or both of the ceramic bodies used in the bonding process contains surface-accessible channels of residual metal, i.e., metal channels which have resulted from molten-metal transport during the ceramic growth process.  When the suitably assembled ceramic bodies are heated in an oxidizing atmosphere at a temperature above the melting point of the residual metal, molten metal at the surface of the ceramic body reacts with the atmospheric oxidant so as to bond the facing surfaces together by a layer of the oxidation reaction product of the molten metal formed therebetween.

In  this fashion,  damage to  the cut/seal head and associated down-time to clear the jam is avoided.

Abstract: ABSTRACT     An apparatus for continuous-direct-resistance heating of works such as long-length articles comprises roll electrodes disposed along a feeding path to contact the travelling work.  An annular tranformer in which the work passing through is disposed between the roll electrodes; and conductive members with sufficiently less electrical resistance than that of the work is located between the roll electrodes disposed on the periphery of the transformer with the both ends thereof connected to the roll electrodes through a slider.  A current is induced in the work with the conductive members as the retrace, which efficiently heats the work, having a higher resistance, without affecting other areas.  If the apparatus comprises three roll electrodes, two transformers are used and conductive members are disposed on the periphery of each transformer and connected to the neighboring roll electrodes, and the power is fed to each transformer from two single-phase transformers in the Scott connection with a three-phase power supply.

Abstract: The invention concerns a method for the generation of smoke for smoke-curing of goods.  The smoke is generated by means of the top-burning technique, the smoke being recovered only when there is a layer of coals that has been produced from the burning of the fuel and that has a thickness of about 0.5 to 100 mm above the layer of fuel.  The layer of coals acts as a regulator of the flow of the combustion air, whereby the burning can be made to take place at a temperature favourable in view of the formation of flavour agents and detrimental sub-stances.  The layer of coals also acts as a selective filter as it removes detrimental sub-stances out of the smoke.
