Abstract: Abstract A boundary - or line-detecting process using image-filtering is used to detect fabric faults (2) in moving, in particular textile, fabric webs (1).  A double-slit mask (16) is used as a filter.  The output signal of the filter is formed from the difference between the two luminosity values averaged across each slit of the filter mask (16).  The image-filtering system is realized either by non-coherent optical spatial filters or by means of digital electronic circuits.  The surface of the fabric web (1) generally has a certain texture which already contains boundary and line elements.  These basic values are used to derive fabric-specific parameters from which the boundary or line elements due to fabric faults (2) are deducted.  The boundary or line elements which remain thus, owing to their increased contrast, unambiguously indicate faults (2) in the fabric web (1).

Abstract: A B S T R A C T           Fluoride-containing wastes, arising in the aluminium industry, particularly spent cell linings from reduction cells, are digested with caustic soda for conversion of sodium cryolite to NaF.          By use of very strong caustic soda NaF may be left in the solid residues after removal of the residual liquor and recovered from such residues by water leaching.          As an alternative weaker caustic soda may be used in the digestion stage and subsequently be crystallised out from the residual liquor, after separation from the solid residues, by evaporating and/or cooling the liquor.   The precipitated NaF is then conveniently redissolved in water.    The NaF solution prepared by either route is then preferably subjected to electrodialysis to recover a solution of HF from it.   Such HF is conveniently converted to AlF3 by reaction with alumina.

Abstract: Abstract Mould Arrangemnt for glassware forming machine The mould arrangement is for use in a cyclicly operating glassware forming machine.  A plenum chamber, forming part of a bottom plate mechanism on which a bottom plate of the mould is carried, extends beneath a mould of the arrangement and has exits through which cooling air may leave the plenum chamber and enter cooling passages in side portions of the mould when the latter are in a closed position thereof.  Air is blown into the plenum chamber for a predetermined period in each cycle of operation of the machine and leaves the plenum chamber through the exits thereby cooling the mould by passing through the passages in the side portions thereof.          The air leaving the plenum chamber may first pass through passages in the bottom plate of the mould which communicate with the passages in the side portions.

Abstract: ABSTRACT    A method of measuring the concentration of a free ligand in a biological fluid containing the free ligand and ligand bound to endogenous binding agent, comprises a)   mixing a sample of the fluid with an analogue of  the  ligand,  a  specific  binder with which the  free ligand and  the  ligand analogue  bind,  and an exogenous binding agent  which binds  the  ligand analogue but not the ligand,  either the ligand analogue or the specific binder being labelled, b)   incubating  the  resulting mixture  so that the ligand  and  ligand  analogue  compete  for  the  specific binder, c)   determining either the amount of the labelled analogue bound to the specific binder or the exogenous binding agent or the amount of labelled specific binder bound, or not bound, to the ligand analogue, and d)   correlating the determined amount to the amount of free ligand present in the sample.      The  method  is  especially useful where the  ligand analogue  binds  with  endogenous  binding  agent  and  the extent  of  binding varies from sample to sample of the biological fluid.  It may be used to measure concentration of  free  thyroid  hormones  and  other  hormones  in  body fluids,  employing  antibodies  specific  to  the  ligand analogue as the exogenous binding agents.
