Abstract: TIME-MULTIPLEX PROGRAMMABLE     SWITCHING APPARATUS                      ABSTRACT OF THE DISCLOSURE             Time-multiplex programmable switching apparatus for establishing on demand time shared connections between pairs of ports.  Signals within the system are digital.  The invention is described in the context of an electronic private automatic branch exchange (EPABX) telephone system.  A central processor unit (CPU) including a recirculating memory carries port address pairs and digital information to be exchanged along with a status word used for identifying program loops.  Program steps are sequenced or initiated by timing signals and signaling data from the port units. Common buses interconnect the port units with the central processor unit.  Port units are grouped with a common buffer memory for converting parallel data from the CPU to serial form.  The CPU memory includes slots for housekeeping functions to detect, inter alia, an off-hook telephone.  The principles of the invention are applicable to telephone central offices and digital switching systems as for computers, for example.  Individual EPABX's may be interconnected for expanded service.

Abstract: ABSTRACT OF THE DISCLOSURE A flame responsive system includes a flame sensor, flame signal generating circuitry responsive to the flame sensor and flame signal inhibiting circuitry also responsive to the flame sensor.  A fast filter and a slower filter are coordinated so that total loss of flame sensor response results in rapid termination of a flame signal output from the flame signal generating circuitry while reduction of a flame sensor response below a set point causes the flame signal inhibiting circuitry to inhibit the flame signal output.

Abstract: DRAPERY HEADING Abstract of the Disclosure An easy and quick method of placing a stiffening heading known as crinoline or Buckram to drapery fabric without the use of a sewing machine and the help of pins or staples.  The invention discloses the use of any drapery stiffening or heading with at least one and preferably two fine lines of adhesive or glue having a low melting point positioned on the heading parallel to the longitudinal side edge thereof.  The drapery fabric is joined to the one line on the stiffening by placing the drapery material into overlapping relation in a straight line over the edge of the heading and one adhesive line.  Heat is applied to the crinoline to melt the adhesive and seal the fabric and heading together and then the heading material is turned 360 degrees within the crinoline and heat is applied over the second line of adhesive to melt the same and seal the heading to and within the crinoline.  In this manner the drapery stiffening is secured in a straight and accurate manner to the top of the fabric whereby the pleats can subsequently be sewn therein.

Abstract: ABSTRACT      An undesired signal canceller for a composite amplitude modulated signal including an undesired signal delayed by a time ?o from a desired signal.  The composite signal is supplied to a detector circuit.  A carrier signal of the same frequency as that of the amplitude modulated carrier and delayed in phase by the time ?o is produced. This carrier signal is amplitude modulated with a signal formed by delaying the output signal from the detector circuit by the time ?o and the amplitude modulated carrier signal is combined with the composite amplitude modulated signal to cancel the undesired signal there-from.

Abstract: Abstract of the disclosure A countercurrent procedure for the extraction of protein from defatted rapeseed meal is described. Using 0.02 N NaOH and a meal to solvent ratio of 1:25 as much as 94 % of meal nitrogen is extracted. A two step precipitation, first at pH 6.0 and then at pH 3.6, the two isoelectric points of the protein in the extract, affords two protein fractions, which contain 69.4 % and 24.3 % of the meal protein, respectively. After washing the curds with water and drying with acetone two highly pure isolates are obtained. Protein Isolate I, light grey, contains 92.9 % protein and Protein Isolate II, white, contains 98.6 % protein, both on a dry weight basis. These protein isolates are light colored, bland products having a foam stability higher than soybean protein. Their amino acid composition shows adequate amounts of isoleucine and sulphur amino acids. Nutritional experiments prove better performance of the protein isolates as compared to the corres-ponding meals.

More particularly, the instant invention is directed to alkali metal halide silver halide-containing photosensitive glasses which, through a unique sequence of shortwave radiation exposures and heat treatments, exhibit the total range of colors seen in the visible spectrum either in the transparent or in the opacified state and in three dimensions.  The base glass composition can be varied widely, but the presence of silver, alkali metal oxide, fluorine, at least one of the group consisting of chlorine, bromine, and iodine, and, where ultra-violet radiations comprise the actinic radiations, cerium oxide is required.  Multi-colored photographs and other unique decorative effects can be  imparted into such glasses.  Where desired, polarization effects can be secured in the glasses.

Abstract: Abstract A method of removing contaminants from the surface of an article is comprised of the steps of providing abrasive particles comprised of a material having the characteristic of reacting with oxygen to form predominately gaseous products of reaction and directing the abrasive particles in impingement onto the contaminated surface. The method is particularly applicable in removing containments from the internal components of air-breathing machines such as gas turbine engines.  The abrasive particles may be entrained in an air stream flowing through the gas turbine engine whereby the particles are directed in impingement against the contaminated components.  The abrasive particles may be comprised of carbon content of at least 70% by weight and a volatile content of less than 8% by weight and may also have an erosivity within the range of 0.004 grams to 0.15 grams.

Abstract: ABSTRACT OF THE DISCLOSURE         A means for decoding a generally constant frequency sine wave scrambled television signal uses an automatic gain con-trol circuit in a closed loop.  The scrambling, applied at the head end of the television system, applies a greater scrambling level to the audio carrier than it does to the video carrier.          The unscrambling signal, the detected audio carrier scrambling signal, is combined with the scrambled signal in an amplifier circuit, the output of which is a basic television signal.      There is a residual of the scrambling sine wave remaining in the audio carrier output, after unscrambling, but little or no residual scrambling remaining on the video carrier.  The residual audio carrier scrambling signal is detected and amplified for application as the unscrambling signal.

Abstract: ABSTRACT OF THE DISCLOSURE              Coal is passed in a two-stage proceeding through a drying and heating zone.  The coal coming from the drying zone is separated from the heat carrier gas which is then passed into the atmosphere after going through an electrodust separator.  The dried coal is delivered into the heating zone.  The hot gases for the heating zone is furnished by a combustion device.  The exhaust gas from the heating zone is separated from the heated coal which is recovered while the exhaust gas is passed back into the drying zone.  Part of the hot combustion gas coming from the combustion chamber is branched off and passed into the exhaust gas coming out of the drying zone either directly behind the drying zone or behind the separator for separating the dried coal from the exhaust gas.          The temperature of the exhaust gas from the drying zone is thus prevented from sinking below the sulfuric acid  or water vapor dewpoint which might result in corrosive damage to the appa-ratus, particularly to the electrodust separator.
