Abstract: Abstract In a continuous process for the extraction of crude refinery stock from oil-bearing sand, miscella produced earlier in the process is returned and mixed with oil-bearing sand to provide a feed slurry which, after heating, is separated into two streams,  one of which is comprised predominantly of the coarser sand particles in the feed sand and miscella and the other of which contains most of the fine sand particles in the feed  slurry.  Miscella  extracted by hot  solvent  from one of these  streams  is  recycled  to  produce  at  least  part of  the miscella returned to produce the feed mix, and the other stream is processed to remove at least most of the sand and yield a miscella which is then distilled to separate the solvent for recycle to the extraction stages. Generally stated, a decanta-tion  step  involving  countercurrent  extraction  of  the  feed slurry will he used with sands which are comprised largely of fine particles.  Percolation and separation of miscella along with solvent extract of bitumen from the sand is used where the sand in the feed mix is predominantly coarse. The spent sand from  both  streams  is  combined,  and  being  still  wet  with solvent,  is  subjected  to  steam  stripping,  yielding  solvent vapor. The hot vapors which result are first used to preheat the  feed  slurry  followed  by  condensation  and separation of solvent, which is recycled into the system, and water. Heat is also  recuperated  from  the  spent  sand  to  preheat  the  feed slurry.

Abstract: Abstract The present invention relates to systems for assessing the quality of illumination provided by a lighting environment to a task location in terms of the ability of that illumination to render the contrast of a visual task at the task location.   Past systems have been inaccurate,  inflexible, or required trained personnel and bulky equipment to make such an assessment.  The present system accomplishes this assessment by generating a series of electrical signals,  each such signal corresponding to the luminous flux impinging at the task location  provided by a  zone  of  the  lighting  environment.    These signals, when associated with the position of the corresponding zones, accurately describe the flux distribution of the lighting environment, and are used to calculate Equivalent Sphere Illumination, a figure of merit for that lighting environment.

Abstract: Abstract The stability of formulations for oral care and dental care, which contain tin(II) salts and water, is enhanced or achieved by adding a cationic surfactant selec-ted from amine salts and quaternary ammonium salts, or a polyol, or a mixture of these; the additive fully preser-ves, or even potentiates, the inhibiting action of tin salts on plaque formation and on dental caries. The novel formulations furthermore advantageously contain, as a solubilising agent and emulsifier, a non-ionic, water-soluble addition product of ethylene oxide which further improves the stabilising action.

Abstract: DIGITAL FILTER            Abstract of the Disclosure A digital filter includes a pair of serially connected second order sections each of which includes delay elements arranged to store the number of bits contained in two complete input words.  Each filter section also includes simple logic comprising adder circuits and inverters but no multipliers.  The logic combines outputs from the delay element with the filter input to form an intermediate signal which is applied to the input of the delay element.  The intermediate signal is also combined with yet other outputs from the delay element to form the filter output.  To eliminate clocking complexity within the filter, the logic is not preset or cleared between each input word.  Instead, the word length is intentionally increased, and the sign bit of each intermediate word is intentionally repeated as the word is processed in the filter, the extra bits acting as an inter-word buffer and serving to protect against spurious overflow and limit cycle oscillations.

Abstract: ABSTRACT         In the manufacture of external and internal shapes from metallic material with  cut faces free of break-offs, the stamping technique can be used only up to limiting values of D/S = 1 or A/S = 1 (D = hole diameter, S = material thickness, A = web or edge width).          Nor does the conventional art of precision cutting achieve sufficient limiting values.  The invention improves the known precision-cutting tools by doing away with the conventional knife-edged rings, instead of which the material to be precision-cut is supported, on  its shell surface outside the cutting line by supporting members located at the side of the cutting punch.          Limiting values, which it has been possible to achieve hitherto only by means of the much more expensive machine-cutting processes, are obtained as a result.
