Abstract: ABSTRACT  A digital burst signal transmission system having a low code error rate and high transmission efficiency suited for multi-directional time division multiplex and time division multiple access communication systems is described.    First circuitry generates a first burst control signal synchronized with an input digital signal and a second burst control signal having a pulse width larger than that of the first burst control signal.  Second circuitry gates the input digital signal in response to the first burst control signal to provide a step-wise digital burst signal.  Third circuitry frequency limits the step-wise digital burst signal and fourth circuitry gates the frequency limited digital burst signal in response to the second burst control signal thereby providing a digital burst signal.  The second burst control signal may have its gating start and end points so timed as to have a substantially zero level on the leading and trailing edges of the output of the third circuitry.

Abstract: ABSTRACT OF THE DISCLOSURE            A coordinate sensing device uses electric currents to energize a conducting member which has a major surface and preferably is made of a mesh material.  Electrical currents are sequentially applied to create alternate non-coincident elec-trical fields so that when a probe is applied to the surface, the obtained electrical potentials can be compared to a reference potential.  The resulting potential differences may then be conveniently converted to appropriate signals.  The conducting member is not limited as to shape or construction; hence, it may also act as an anti-glare device for a cathode-ray tube.  The fields created by the electrical currents need not be uniform.

Abstract: ABSTRACT            In a process for the production of ethanol through conti-nuous fermentation of a carbohydrate containing substrate which contains fermentable substance as well as non-ferment-able soluble and solid substance, the substrate is hydrolyzed in a hydrolysis step     and fermented in a fermentor comprised in a continuous process circuit comprising the fermentor    , a yeast separation step      and a distillation step    . From the fermentor a stream     of fermentation liquor is continuously withdrawn, and is then separated into a stream      enriched in solid substance, which is discharged from said process circuit, and a stream      impoverished in solid substance, which is fed to said yeast separation step     . From the yeast separation step a yeast concentrate stream      is recirculated to the fermentor and the yeast-free stream is sent to the distillation step    , wherein ethanol is distilled off and a remaining stillage stream is obtained, part of which is continuously recirculated to the fermentor or to the hydrolysis step     .

Abstract: ABSTRACT OF THE INVENTION         A manually operable, compact apparatus for sequentially cutting sections of film, each of which includes a visible photographic image and mounting the same in a frame for subsequent use in a projector or viewer.  The apparatus is specifically adapted for use with frames of the type which have a pair of open-ended guides for receiving the film.  The apparatus includes structure for supporting the frame at an acute angle relative to a plane containing the path of movement of an advancing section of film.  By so inclining the frame relative to the path of movement of the film, the leading edge of the advancing film is deflected by a portion of the frame in a predetermined direction and along a well-defined path into the open end of each of the two film guides.  The apparatus also includes means for maintaining a trailing edge portion of the section of film to be mounted in a generally horizontal plane during the deflection of the film's leading edge.  Accordingly, after the leading edge of the film bottoms out at the closed end of each guide, and the trailing edge is severed from the remainder of the roll of film, the trailing edge moves in a direction to relieve the stresses in the severed section caused by the deflection of the leading edge of the film.          This latter movement results in the trailing edge of the severed section being automatically located in operative relation with the aforementioned frame portion.

Abstract: ABSTRACT OF THE DISCLOSURE           Process for stabilizing pellets of pulverulent mineral materials, for example, iron ores, dolomite, carbonate or phosphate salts for agriculture and the building trade or the like, which are unstable because of redrying, hygroscopicity or reaction with the atmosphere.  After they are formed by the well-known buildup granulating process with addition of pelletizing liquid, the pellets are provided with a coating of a mineral material, which is insoluble or only slightly soluble in water.  The coating can be applied by dusting the pellets especially with the oxide of a metal of the second main group and subgroup, the oxide being in the form of a dry powder, and hydroxylating by means of water or by spraying an agent in liquid, dissolved or dispersed form, which forms an insoluble or slightly water-soluble compound by reaction with the pellet material.

Abstract: ABSTRACT A colorimeter for measuring color of an object, in particular for measuring the color of liquids such as paints in a process stream.  In the colorimeter, a single analytical light beam, with its blue and red intensity ratio controlled through a feedback loop, is directed to a sample whose color is being measured.  A portion of the analytical light beam is reflected from the sample into a grating monochromator which disperses the light beam into its spectra.  A detector array is attached to the monochromator which converts the spectra of the light beam into discrete signals which are then multiplexed with instrument status and reference color signals into an A/D converter.  The output of the A/D converter is then fed directly to a computer programmed to directly provide standard color values.
