Abstract: ABSTRACT OF DISCLOSURE                     PALLET WRAPPER     A pellet wrapper adapted to wrap a pallet with a web material comprises, an anvil member movable into position against the side of the pallet, a clamp movable with the anvil and adapted to hold the end of the web with which the pallet is to be wrapped.  With the clamp and anvil so positioned adjacent the pallet, the wrapping of the pallet is begun.  After the web has wrapped around the pallet at least sufficient turns so that the web overlies the end retained in the clamp and secures this end portion against the side of the pallet, the clamp is then released and retracted and the wrapping of the pallet completed to wrap the pallet and then back to overlapping the layer of web material initially applied to the pallet while forming said web in about the last 1-1/4 turns into roped form.  After the pallet has been wrapped the clamp is again moved into an operative position to clamp a roped section of the web and a suit-able securing mechanism is advanced to cooperate with the anvil to secure the web adjacent the clamp to the underlying roped layer of the web and then a cut-off mechanism is advanced to cut the web between the clamp and the point of securement.

Abstract: ABSTRACT       In a cutting machine tool with a number of cutting edges the cutting edges are placed on the tool in accordance with a sequence consisting of random binary numerals.  The cutting edge of the tool is divided into a number of sections correspond-ing to the number of numerals of the sequence, and for each binary "1" of the sequence there is a cutting edge on the appertaining section on the tool, while binary "0" represents absence of a cutting edge on the section.       Using the tool makes it possible to lower the A-weighted noise level, since part of the noise is moved to frequency ranges where the noise is not so irritating or harmful and/or where the noise emission is limited by a larger mechanical damping or by similar means.       The tool can be made by removing at random a considerable number of the cutting edges from a tool with cutting edges uniformly spaced.

Abstract: ICE AGGREGATE ROAD AND METHOD AND  APPARATUS FOR CONSTRUCTING SAME     Inventor:  Edwin N. Fisher ABSTRACT OF THE DISCLOSURE   A method and apparatus for constructing an ice aggregate structure, such as a road, at all sub-freezing temperatures likely to be encountered at high latitudes, including below -45°F.   Initially, ice is mined, crushed and then stripped of substantially all "fines", i.e., ice particles smaller than approximately 0.1 inch.  The resulting crushed ice aggregate is then distributed and placed to the desired grade without requiring surface work or compaction.  The upper thickness of the crushed ice aggregate is then bonded by spraying heated water thereon during single or multiple passes.  Apparatus is provided to prevent evaporative cooling of the spray water prior to its contact with the crushed ice surface, which pre-ferably comprises an enclosure or flexible skirt which extends around the spray nozzles downwardly to the ice aggregate surface.  Substantially immediately following the final spray pass, normal wheeled traffic, such as machines utilized to form the ice aggregate road and to transport crushed ice and bond water, can be permitted to traverse the bonded crushed ice aggregate.   A preferred embodiment of a crushed ice placement and bonding machine is disclosed which permits a smooth ice aggre-gate surface to be constructed over uneven terrain.  The machine is capable of changing grade as may be required to ramp-on or ramp-off a structure or to clear a natural obstruc-tion, and includes means for incorporating super-elevation (banking) into road curves.  The machine is totally self-contained and self-sufficient, and permits construction, on a continuous flow basis, of roads and other civil structures over natural terrain without any machinery contact with the terrain.  That is, the machine is capable of operating from the surface that it constructs.

Abstract: ABSTRACT OF THE DISCLOSURE         For the manufacture of acetylene and synthesis or reduction gas from coal by means of an electric arc or plasma process, powdered coal is pyrolised in an electric arc reactor with an energy density of 1 to 5 kWh/Nm3, a residence period of 0.5 to 10 msec and temperatures of at least 1500°C such that the gaseous compounds derived from the coal do not exceed 1.8 times the so-called volatile content of the coal.  The coke remaining after quenching is then fed to a second electric arc reactor in which the coke by means of a gasifying medium and heating by means of an electric arc or plasma process is converted into synthesis or reduction gas during a residence period of 1 to 15 sec and a temperature of at least 800°C.  The gas flow from the pyrolysis zone is cleaned and acetylene is recovered therefrom by selective sol-vents.  The gas from the cleaning stage is similarly cooled and cleaned.  Use of the process permits a saving of about 50% of direct fossil energy requirements whilst achieving gasification of the coal.

Abstract: SELF EXTENDING MEMORY FILE                    ABSTRACT OF DISCLOSURE            What is disclosed is a memory assignment method used with a disk file management system operating with a hard disk memory wherein data is stored in appropriate ones of a number of discrete files on the disk, and each file has an assigned amount of memory space exclusively associated therewith for the storage of data that should be in the file.  The disk file management system keeps track of how much of the memory dedicated to the exclusive use of each file on the disk is yet available for the storage of data in each file, and also keeps track of how much of the memory on the disk is yet available for storage but has not yet been assigned to the exclusive use of any particular file.  When the system determines that the amount of not yet used memory dedicated to the exclusive use by a file for the storage of data has reached a predetermined low level the system automatically takes a predetermined amount of memory not yet assigned to the exclusive use of any file and transfers it to the exclusive use of the file with the low level of not yet used memory.

Abstract: ABSTRACT OF THE DISCLOSURE         To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content  of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%.  Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjcected to surface quenching by a cooling medium,  preferably water, so that the steel in a rim zone R1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage.  Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.

Abstract: ACOUSTO-OPTIC FREQUENCY SHIFTER UTILIZING MULTI-TURN OPTICAL FIBER       Abstract of the Disclosure A fiber optic frequency shifter comprises an optical fiber having an acoustic conducting medium for propagation of an acoustic signal.  The acoustic medium is preferably shaped  as  a  rod,  and  the  acoustic  signal  propagates longitudinally down the rod.   The optical fiber is wound around the rod with plural turns such that the axis of the fiber is at an angle relative to the wave fronts of the acoustic  signal.    As  the  acoustic  signal  propagates through the rod, it causes stress on the portions of the fiber in contact with the rod.   The stress on the fiber caused by the acoustic wave causes optical energy to be transferred between two propagation modes of the fiber. This transferred  energy is shifted  in frequency by the frequency of the acoustic signal.  By tightly winding the turns  of  the  fiber,  high  frequency  shifts can  be obtained.
