Abstract: ABSTRACT OF THE DISCLOSURE      A net jointing structure has a pair of warp-knitted net adapters for use in coupling or jointing confronting net ends together.  Each of the adapters has a net region and a web region, the net region being subdivided into a plurality of net sections which are formed of a plurality of meshes made of warp chains and are progressively smaller in mesh size.  The net section of the smallest mesh size is coupled to the web region and the net section of the largest mest size is adapted for connection with one of the net ends.          The web region carries a stringer of a sliding clasp fastener and includes a plurality of warp chains uniformly spaced along the length thereof, the warp chains in the web region being extensions of the warp chains in the net region.  In-laid threads are included in the net region where they run in and along the warp chains and in the web region where they extend coursewise across and over several warp chains to keep them in uniformly spaced relation to each other. The advance in the art is in that a sliding clasp fastener stringer can be fixed to the jointing structure with ease.  The stringer, when attached, is prevented from getting puckered or otherwise deformed.  Thus, the net jointing structure can hold the attached sliding clasp fastener stringer stably in place to aid in smooth and reliable operation of the sliding clasp fastener.

Abstract: ABSTRACT OF THE DISCLOSURE     Pre-stressed polyethylene foil is shredded mechanic-ally in a closed vessel, whereby it is heated until it shrinks and its surface becomes tacky. When latex is sprayed into the vessel, a thin rubber layer covers each foil fragment and is thermally welded to the polymer surface. The rubber layer traps pockets of aqueous latex in voids of the shrunken foil. The weight and bulk of the resulting material are much greater than the corresponding properties of its rubber content so that precisely measured amounts of rubber may be dispersed quickly and uniformly in hot asphalt for improving the pro-perties of a road surface made from the asphalt mixture. The water content of the rubber-coated plastic fragments improves the working properties of the asphalt mixture.

Abstract: HIGH CURRENT GROUNDING ASSEMBLY HAVING RIGID          INTERCONNECTING CONDUCTORS                 ABSTRACT OF THE DISCLOSURE           A high current grounding assembly especially adapted for electrically interconnecting and grounding substation phase busses conductors is provided which includes rigid metallic connector elements capable of handling extremely high fault current loads without violent whipping or other motions.  The clamp and connector assembly, or one of the phase busses, is connected to ground in order to protect linemen or other workers in the vicinity of the assembly from the effects of fault or inductive currents.  In preferred forms, novel conductor- gripping clamps and rigid tubular connector elements may be partially or completely preassembled and thereafter installed on phase busses. The clamps include a shiftable gripper for engaging a respective phase conductor, with a pair of transversely disposed clamp sections on the underside of the gripper for receiving and gripping the rigid connector elements; this construction presents the shortest possible current path through the clamps, which is important when very high fault currents or the like must be grounded.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for detecting the presence, location, and concentration of moisture in multiple layer built-up roofs.           A plurality of spaced points are first marked and located on the roof to be tested.  The relative dielectric constant of the roof at each of the spaced points is then measured, the measurements are recorded, and each measurement is associated with the location of the point at which the measurement was taken.  The magnitude of the relative dielectric constant of the roof is proportional to the relative concentration of moisture in the roof covering, thus allowing the points at wet portions of the roof to be distinguished from points at dry portions of the roof. statistical methods may be employed to better separate the measurements taken at dry points on the roof from measurements close in magnitude which are taken at wet points on the roof.

Abstract: ABSTRACT OF THE DISCLOSURE     A  method for the separation of a mixture of fine particles wherein the fraction to be separated has a surface which is more reactive chemically than the remaining fractions by grinding the mixture so that the fraction to be separated has a particle size of less than 50 µ, suspending the ground mixture at a temperature less than 100°C in a diluted aqueous solution of zirconium oxychloride or zirconium oxynitrate, allowing the solution to settle and decanting the deposited material and then adding a base to the decantate to precipitate the residue therein.  This process allows selective separation of the fractions having a more chemically reactive surface without the use of complex equipment and with a minimum use of expensive additives and chemicals.

Abstract: ABSTRACT OF THE DISCLOSURE         A mode selecting assembly for a recording and/or reproducing apparatus includes at least one operating member, which is displaced to change the apparatus over to an operating mode.  The operating member is displaced by the revolution of an operating gear having a toothless portion and the operating gear is driven by a pinion.  The engagement of the operating gear with the pinion is triggered by a trigger member responsive to the depression of a corresponding operating push button.          The operating gear is prevented from further rotation after the establishment of the selected operating mode by a locking member when the selected operating push-button is continuously depressed.          The mode selecting assembly further includes timed recording capability wherein the pinion in engagement with the end of the toothed portion of the operating gear maintains the trigger means in an inactive state to place the apparatus in a preparing mode for timed recording.  At the preset time, the preparing mode is released by a releasing member and the operating gear is rotated to its original inoperative position where the toothless portion faces the pinion to disengage the operating gear from the pinion.

Abstract: Abstract of the Disclosure A system for automatically adjusting text codes and control codes stored in a memory into text blocks having variable formatting parameters and variable line counts.  The detection of a code signal causes the system to enter a non-playout adjust mode.  The operator is then prompted to enter a line count for the text block to be formatted.  After the line count is entered, the system proceeds to adjust the number of lines of text equal to the line count to the predetermined formatting parameters.  An interrupt of the adjust mode occurs upon the detection of the end of text, mode-measure codes in memory, special codes (e.g. stop, edit, error, page end) hyphenation requests forced line overflow, or upon completion of the text block line count.  The system presents to the operator visual indicators upon the occurrence of an interrupt suffi-cient to define the cause of the interrupt and the location in text where the interrupt occurred.  During the interrupt, the operator may enter information into the system or play out codes from memory, and then enter a code signal that causes the system to continue in the non-playout adjust mode.
