Abstract: A method of producing a ceramic material includes the step of heating at a temperature between 1200° and 2000°C a mixture containing silicon nitride in an amount up to 98% by weight of the mixture together with between 1% and 60% by weight of aluminium nitride, between 0.5% and 50% by weight of silica, and between 0.05% and 60% by weight of alumina, some but not all of the silica in the mixture at said temperature being present as an impurity contained by the silicon nitride. The silicon nitride, aluminium nitride, alumina and silica produce at said temperature a reactable composition which constitutes at least 95% by volume of the mixture and in which the silica is present in a molar ratio of 1:2 with part of the aluminium nitride and the alumina is present in a molar ratio of 1:1 with the remainder of the aluminium nitride, and the constituents of the reactable composition react together to produce the required ceramic material.

Abstract: INTERCONNECTORS FOR FOOD PROCESSING EQUIPMENT      ABSTRACT OF THE DISCLOSURE           The permeate tubes of spiral-wound, reverse osmosis or ultra-filtration modules are serially joined to one another by tubular connectors lined with resilient sealing material.  The lining extends beyond the ends of the connectors and is tapered to seal the connector and the permeate tubes under normal operating pressures.  A resilient washer may be inter-posed between adjoining ends of the permeate tubes within the interconnectors as an integral part of said interconnectors for absorbing the hydraulic shock which normally occurs when flow directions are reversed in filtration units including such spiral-wound modules.  Specially constructed anti-telescoping devices adapted for engaging the interconnectors and the ends of the spiral-wound modules are also disclosed.

Abstract: Abstract of the Disclosure The computer centre of a railway system constantly exchanges data with the interlocking stations.  The inter-locking station contains a data transmitter and a data receiver.  In the data receiver a sync pulse is derived from the incoming data words and used to control the data transmitter so that the beginning of an incoming data word coincides with the beginning of a transmitted data word.          This results in a constant time relationship between the data words arriving in the computer centre and the clock rate of the computer centre.

Abstract: ABSTRACT OF THE DISCLOSURE:           A process for the production of 1,1-difluoroethane by the hydrofluorination of acetylene in the presence of a catalyst containing aluminium fluoride.  The hydrofluorination reaction is carried out at temperatures of from 150 to 350°C with a residence time of from 1 to 60 seconds.  The catalyst utilized is prepared by impregnating .gamma.- or .pi.-aluminium oxide with a solution of a bismuth and a manganese salt, followed by heating to temperatures in the range from 150 to 250°C, initially in a nitrogen atmosphere and then, after complete drying, with a mixture of air and increasing concentrations of hydrogen fluoride up to a 100 % hydrogen fluoride atmosphere, the completed catalyst containing 0.1 to 20 % by weight of bismuth, 0.1 to 10 % by weight of manganese, 20 to 38 % by weight of aluminium, 32 to 60 % by weight of fluorine and, for the rest, of oxygen.  This process gives yields of from 96 to 98 % of the required 1,1-difluoroethane, the conversion of acetylene being almost complete.  1,1-difluoroethane is an important inter-mediate product for the production of vinylidene fluoride or for the production of fluorinated hydrocarbons of the type used as cooling liquids.

KOBIELLA, a citizen of the United States, residing at 3802 Pheasant Drive, Rolling Meadows, in the County of Cook and State of Illinois, have in-vented a new and useful improvement in AUTOMATIC STRAPPING MACHINE of which the following is a specification.               Abstract of the Disclosure An automatic strapping machine is disclosed wherein strap is fed at a high rate of speed about a package so as to form a loop which is then tensioned and sealed.  The loop is formed so that the leading end of the strap is overlapped by a trailing end of the strap and the resulting overlapped strap portions are joined together so as to form a seal which is not susceptible to snagging.  The distal end of the overlapping strap end portion is urged against and is moved back and forth relative to an underlying strap portion in tension at a high rate of speed so as to generate heat therebetween and to form a friction-fused joint.  During joint formation the strap loop about the package is in tension, but the strap end portion over-lapping the loop is relaxed, i.e., not in tension.         Sealing energy generating means is adapted to engage the distal end of the overlapping strap end portion and comprises a pivotable anvil and a rotatable - oscillatable hammer adapted to receive overlapping strap regions therebetween, and an oscil-lating motor means for the hammer which engages the loop-over-lapping strap end portion and rubs the overlapping end portion against the underlying strap region at a rate sufficient to melt an interface region therebetween and to form a friction-fused joint when energized by the oscillating motor means.
