Abstract: ABSTRACT   The strength of ice is reduced by the dissolution of a water-soluble composition composed of (A) a non-or slightly-ionizing water-soluble organic compound containing one or more hydrophilic groups, and (B) an organic or inorganic, water soluble ammonium salt, optionally with surface active agent or water and conven-tional additives in ice-forming water.  The composition is particularly suitable for application to a wet, particu-late solid material prior to its storage or transportation in sub-freezing weather to produce a frozen mass of reduced mechanical strength, thereby greatly mitigating subsequent unloading or handling of the material.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic tape loading and unloading device for a magnetic tape recording and/or reproducing apparatus includes a cylindrical tape guide drum having at least one rotary mag-netic head which moves in a circular path substantially coin-ciding with the circumferential surface of the drum.  The tape used in the apparatus is stored on supply and take-up reels having the tape wound thereon in a tape holder such as a cassette or cartridge and in use the holder positions the tape supply at a relatively lower level with respect to the tape guide drum.  The device further includes a first tape engaging member, for example, tape guide pins, carried by levers which are rotatable about a fixed pivot to draw the tape from the tape supply reel in a diagonally upward direc-tion to the tape guide drum where it is helically wrapped about at least a portion of the circumferential surface of the drum and a second tape engaging member to draw the tape from the tape supply reel in a horizontal direction opposite to the direction of movement of the first tape engaging member.

Abstract: ABSTRACT OF THE DISCLOSURE A countercurrent liquid-solid contacting apparatus having combined filtering and regenerating columns stacked one above the other is provided. The filtering column has a liquid inlet and outlet, a liquid medium to be filtered being supplied into the filtering column through the liquid inlet and discharged to the outside through the liquid outlet after having passed upwardly through a bed of filtering or adsorbing material within the filter-ing column.  The regenerating column has its bottom end opening into the filtering column and supplies a filtering material in an amount necessary to compensate for a reduction in the amount of the filtering material within the filtering column each time a portion of the filtering material in a lower region of the filtering column is withdrawn and then transported back into the regenerating column.  Since the regenerating column is a closed vessel, pipe lines sealed to the atmosphere by liquid medium extend-ing outwardly from the liquid outlet and also from the regenerating column have a predetermined relationship with each other.

Abstract: ABSTRACT OF THE DISCLOSURE         Crystalline type-A zeolite powder is used as a phosphate substitute in detergents.  For this purpose it is advantageous that the crystalline type-A zeolite powder has a defined average particle diameter of 4.3 to 8.5 µm and a defined narrow particle size distribution.  These requirements of the product are satisfied by a specific sequence in the addition of the reactants in the precipitation of the zeolite A.  Sodium-aluminate liquor and sodium-tetrasilicate solution are added simultaneously to the water in a reactor and after a lengthy stirring phase further sodium-aluminate liquor and further sodium-tetrasilicate solution are added.  The maximum grit content of the type-A zeolite powder obtained is 0.2%.

Abstract: Abstract:    The invention relates to a method and apparatus for identifying objects (e.g. consumer products in a super-market) appearing in random positions and orientations and for random times on an image window and having an identification on the surface facing the image window in the form of a data field having contrasting indicia in at least one data track.  The data field is first scanned with a scanning raster until a product identification code is recognized denoting the position and orientation of the data track.  The data track is then read with a closely-spaced reading raster and converted to a videosignal.  The amplitude of the videosignal is coded into binary digits at discrete time points and the digits are stored in a memory matrix organised into columns and rows in such a manner that an image of the data track is stored in the memory.  Mutually overlapping partial regions of the memory are than read out in a pre-arranged sequence and fed to a decoder capable of accepting and decoding the information in this form.  In this way, the information is converted from a row-by-row sequence produced by the reading raster into a succession of digits corresponding to individual partial regions of the data track for the recognition of individual symbols appearing therein.

Abstract: ABSTRACT           The method for forming a metallic, dielectric or semiconductor modified amorphous glass material in-cludes the steps of forming a fluid host matrix material on a substrate surface having relative movement thereto, such as a wheel; directing a fluid modifier material in a stream, as from a nozzle toward the substrate surface in a direction such that it converges with the host matrix material; maintaining the temperature of the sub-strate or wheel between 4.2°K and ambient room temperature while rotating the wheel at a velocity of 1000 to 5000 rpm to obtain a surface velocity of between 1000 to 4000 cen-timeters per second thereby to obtain rapid quenching of the host and modifier materials as they contact one another at a rate of from 104 to at least 108°C per second or more to produce a ribbon of modified amorphous glass material in which the electrical and optical transport properties and the number and type of electronic con-figurations can be controlled.  The modified material can range from an alloy to various degrees of alloying and modification to one in which only modification and doping actions exist.  This provides a new method of synthesizing materials in which modifier atoms can be incorporated at various intervals or layers or a bulk material whose sur-faces can be distinctly chemically different from the bulk interior can be made by this process.  For example, rel-atively soft substrate bodies with an exceedingly hard surface or different chemical, electrical or optical pro-perties can be made throughout the material.  By uti-lizing gases as well as liquids even a complete bulk material can be made and yet have a controlled oxidized surface or layer.  Further, not only liquids and gases can be utilized, but solids which can chemically interact with the velocity deposited materials can be utilized to add another type of modification.  The apparatus can in-clude metal spinning apparati such as reservoirs, nozzles and the wheel for carring out the method.
