Abstract: Title of the Invention MAGNETO-ELASTIC TRANSDUCER                  Abstract of the Disclosure A transducer for magneto-elastic stress measurement is formed of a holder and a core of magneto-elastic material provided with coils to generate a flux in and sense flux alterations produced by stresses of the core.  The core is formed of one or more plates firmly attached to the holder and designed to be attached to the measuring object.  The core may consist of a single plate attached to the holder at four symmetrical points, or of a cross having four arms the ends of which are welded to a frame of magnetic material which is secured to the holder.  The holder may also be in the form of a casing of magnetic material which protects the core and coils and serves as a magnetic return path for the fluxes.  For applica-tions where disturbing magnetic fields may occur in the measuring object, the casing is preferably made of non-magnetic material and provided with a frame of magnetic material as a return path for the flux.

Abstract: ABSTRACT           A cyclic process for removing lower valence nitrogen oxides from gaseous mixtures includes treating the mixtures with an aqueous media including sulfuric and/or nitric acid and a peroxygen substance to form nitric acid and other higher valence nitrogen oxides wherein the ratio of the peroxygen moiety to dinitrogen trioxide (N203) and nitrogen dioxide (N02) is greater than the stoichiometric amount and the treating tempera-ture is not more than about 100°C.  Highly selective recovery of nitric acid and/or nitrates in high purity and yield may then follow.         If present in such gaseous mixtures, sulfur dioxide is best removed first, as in a cyclic process including treating these mixtures with aqueous media including alkali metal carbonate/bicarbonate where the ratio of alkali metal to sulfur dioxide is not less than about 2.     The sulfur values may be recovered from the resulting carbonate/bicarbonate/sulfite-containing product aqueous media as alkali metal sulfate or sulfite salts which arc removed by crystallization from the carbonate-containing product aqueous media.  Where the sulfur dioxide is not removed in this manner it may alternatively be recovered as sulfur dioxide, sulfuric acid, or as an alkali metal or alkaline earth metal sulfate.     Where the gas mixture includes both sulfur dioxide and lower valence nitrogen oxides, the processes for removing and recovering lower valence nitrogen oxides and sulfur dioxide may be combined into a single removal/ recovery system, or may be advantageously effected in sequence.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to electrical connectors for use on printed circuit boards, and in particular to multiconductor connectors.  Prior art female circuit board connectors have typically included one or more resilient contacts which extend perpendicular to the surface of the printed circuit board.  In order to avoid concen-trated stresses which would permanently deform the contacts each time a mating connector is engaged therewith, these contacts must be fairly long.  It is often desirable to stack printed circuit boards closer together than has been allowed by the length of these connector con-tacts.  The contacts in the present invention are bent such that an intermediate portion of the contact is substantially parallel to a surface of the printed circuit board.  In this way, the necessary contact length is provided without necessitating an undesirable separation between adjacent printed circuit boards.  The contacts are enclosed in a housing which has one opening for the projection of one end of the female contact therethrough thereby forming a terminal portion for the contact, and a second opening near the other end of the female contact to receive the meting male contact.  The latter-mentioned end of the female contact is bent to form a wiping contact portion.

Abstract: ABSTRACT                SYNTHETIC IMOGOLITE    An inorganic material skin to imogolite is synthesised.          Imogolite is a natural product having tubular structure and occurs in some soils.  The synthetic product has tubes of 13-17% greater diameter, and is made by preparing an aqueous hydroxyaluminium silicate solution containing up to 0.5 molar aluminium and of pH 3.1 to 5.0 by acid-hydrolysing aluminium alkoxides and (introduced not earlier than the alkoxide) tetraalkyl silicate.  The atomic proportion of Si: Al is up to 0.6:1.  The solution thus prepared is digested, say at 96°C for a day, until a product is obtained displaying discernible electron diffraction peaks at 1.4.ANG., 2.1.ANG. and 4.2.ANG..  The synthesised imogolite finds use as a molecular sieve, a catalytic material, or a gel former or sorbent.
