Abstract: A calcium and/or nutritional mineral fortified milk or milk powder product utilizes pyrophosphates or orthophosphates in combination with maintenance of pH within the range of 6.5 to 7.5 to render the milk heat stable. Additional calcium and/or nutritional mineral is added in soluble form either before or after the phosphate addition. The preferred orthophosphates are one or more of monosodium dihydrogen orthophosphate, disodium hydrogen orthophosphate, trisodium orthophosphate, monopotassium dihydrogen orthophosphate, dipotassium hydrogen orthophosphate and tri potassium orthophosphate. Addition of an alkaline agent to adjust the pH is not needed if an appropriate mix of orthophosphates is used. The milk products or milk products recombined from milk powders are heat stable and do not have the problems of translucency, gritty mouth feel or sedimentation which can be associated with other stabilized fortified milks.

Abstract: A pixellated diffractive device includes a multiplicity of pixels (12,22) in turn divided into multiple sub-pixels (13,23). The device is related to one or more pixellated diffraction surface structures which when illuminated generate respective corresponding optically variable images.

Abstract: A boning process and apparatus for separating meat and bone, particularly ribs, in an animal carcass. The spine (12) is restrained relative to the ribs (16) and which are moved in an arc (A) so as to dislocate the joints (17) and to sever connective tissue. This exposes the ribs (16) at the dislocated joints (17) and the exposed ends (16a) are moved along a line (B or C) to progressively extend the exposed portions (16a) so as to separate a major part of each rib (16) from tissues (20) remaining attached to the spine (12). Cuts (21, 22) are formed in the tissues adjacent to the spine (12) and adjacent to the joint (17) to assist in exposing the ribs (16).

Abstract: A relatively dense composite refractory material which has reasonable strength and good thermal shock resistance comprises an alumina matrix material within which are dispersed particles of polycrystalline zirconia comprises from 1.0 to 40 percent by volume of the composite material. Each particle of zirconia is an agglomerate of microcrystals which are strongly bonded together. Due to the agglomerates of the bonding together of the microcrystals at their grain boundaries. The microcrystals contain no matrix material within their agglomerates, and exhibit strong thermal expansion anisotropy. They have a size such that cracks do not form spontaneously within the agglomerates during cooling from about 1600.degree. C. to room temperature. Typically the agglomerates have a mean diameter of from 10 to 15 micrometers, while the average diameter of the microcrystals in an agglomerate is from 1 to 2 micrometers.

Abstract: An apparatus for automatically processing an animal carcass (8). Suspension means (122, 123) suspends the carcass (8) in an inverted position with the spine inclined upwardly towards the neck (11) with the spine located beneath the carcass (8) and so that the diaphragm (119) is approximately vertical. A cutting assembly, (130) moves into the abdominal cavity adjacent to the diaphragm (119), and a cutting means (28) cuts the diaphragm (119) around the periphery. A brisket shearing means (21) cuts the brisket (20) with a shearing action along the brisket (20) from the abdomen and towards the neck end of the brisket (20). The reaction member (188) is pivotally movable relative to the brisket (20) about a rear end to generally follow the contours of the brisket (20).

Abstract: An apparatus to measure the bending length and bending rigidity of a piece of fabric comprising a generally planar surface upon which the plate of fabric is moved. The surface terminates at one end with an edge over which a leading end of the fabric passes. An optical device defines a plane extending downwardly from the surface edge at approximately 41.5 degrees. The optical device detects when the plane is intersected by the leading end of the fabric when, after a sufficient length of the piece of fabric has passed beyond the surface edge to cause bending of the fabric piece, the leading edge of the fabric intersects the plane.

Abstract: A process for the production of ethylene from a methane rich gas stream and an ethane rich gas stream. The process comprises the steps of:(a) introducing the methane rich gas stream together with molecular oxygen into a lower zone of a fluidized-bed of particles which are catalytically active in promoting an exothermic oxidative coupling reaction to produce ethylene and other hydrocarbons,(b) mixing the ethane rich gas stream into the fluidized-bed above the level at which substantially all of the molecular oxygen has been consumed, and(c) subjecting the mixture resulting from step (b) to an endothermic pyrolysis reaction in an upper zone of the fluidized-bed to produce further ethylene and other olefinically unsaturated hydrocarbons.The process is characterized in that the pyrolysis step (c) is carried out substantially without the addition of heat to the reactor, other than the heat content of the methane rich and ethane rich gas streams and the heat generated by the exothermic oxidative coupling reaction.

Abstract: DNA sequence elements which effect anaerobic induction of genes in plants are identified and characterized. These sequence elements, designated anaerobic regulatory elements, confer inducibility by anaerobic conditions on downstress plant-expressible promoters and their associated structural genes. In particular, those sequences associated with anaerobic induction of the maize alcohol dehydrogenase and aldolase genes have been identified. These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to produce chimeric, anaerobically inducible genes. Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

Abstract: A method of forming a dense ceramic product comprised of silicon nitride and silicon oxynitride or aluminum substituted derivative of either in which silica is subjected to a controlled partial carbothermal reduction process in the presence of nitrogen to produce residual silica and silicon nitride, fabricating the resulting material into the desired shape and heating in a nitrogen atmopshere at a temperature of from 1400.degree. C. to 2000.degree. C. with or without pressure to form the product. The silica may conveniently be derived from pyrolysed rice hulls. The product may also comprise silicon carbide, which may be derived from the carbothermal reduction, and a glassy phase.
