Abstract: ABSTRACT METHODS AND APPARATUS FOR ERECTING TRAY TYPE CARTONS In the erection of rectangular tray-type cartons from blanks of foldable sheet material, corner tabs which are to be uppermost in the erected carton are first folded up from the plane of the blank, which is then passed through a die by a punch to form the side wall. On completion of the stroke of the punch, the pair of opposed elongate panels which carry the uppermost tabs are folded outwardly by folding bars carried by the punch. The partially erected carton is then transferred to a continuously moving conveyor and the other pair of elongate panels are folded outwardly by oscillating fingers and plough bars. The upstanding tabs are then heated by travelling hot air jets and pressed down by pressure rollers to seal them to the other tabs and complete the horizontal peripheral flange which extends continuously around the carton.

Abstract: ABSTRACT OF THE DISCLOSURE:         A frame alignment word has N predetermined bits distributed in the frame of a digital transmission signal. Each frame is divided into a number of sectors.  Each sector has a heading made up of a bit or a bit group from the alignment word such that when placed end to end the headings in the frame form the alignment word.  According to a frame alignment recovery method, bit groups are successively taken from the digital signal received at the sector frequency, each taken group having a maximum bit number equal to the bit number in each heading.  The taken bit groups are compared with the heading bits corres-ponding in the frame alignment word and N-1 circular per-mutations thereof.  The comparisons are halted before reaching the full alignment word once the comparison of bits between the heading bits and taken successive groups reveals some disagreement.

Abstract: ABSTRACT                           MELT DISPENSERS           A melt body (16) for a melt dispenser is disclosed which is particularly suitable for use in a hand held hot melt glue gun for use with rods of hot melt glue.   The melt body including a melt chamber (17) provided with a series of fin elements (23) which define passageways terminating at an outlet (21).   The fin elements increase in size progressively from an inlet (19) of the melt chamber to the outlet and ensure good transfer of heat to material to be melted.   Edge surfaces of the fin elements provide surface portions of an opening adapted to receive the central portion of a rod as the rod is fed into the melt chamber.   The shaping of the fin elements is such as to permit convenient manufacture by a die casting process.   The spacing of the fin elements is selected so that melted material flows from the outlet when its viscosity has been reduced to an appropriate value to ensure good adhesive bonding.   The arrangement permits improved consistency of heating the material and thus improved control of temperature of dispensed material.   Also described is an improved hand held hot melt glue gun incorporation such a melt chamber, and incorporating a trigger operated feeding means (14).

Abstract: ABSTRACT           This invention is a process for preparing an insoluble strong-acid cation-exchange resin in acid form modified by the partial neutralization of its cation--exchange capacity with aminoalkanethiol.  The process is characterized by contacting the cation-exchange resin with an N-(2-mercaptoalkyl)amide in the presence of water under reaction condition sufficient to produce the modi-fied cation-exchange resin.  The partially neutralized resin can be treated further by contacting it with an aldehyde or ketone under reaction conditions sufficient to convert the aminoalkanethiol moieties to thiazolidine moieties.  These partly neutralized resins are useful as catalysts in the preparation of bisphenols from phenol and carbonyl compounds.

Abstract: MAGNETIC DISK COATING METHOD AND APPARATUS          ABSTRACT     A rigid magnetic disk substrate is spin coated using a closely confining, stationary air barrier adjacent the surface being coated.   The coating is applied through a slotted opening in the air barrier which is progressively closed as the coating is applied and completely sealed during the spin-off operation.   During the application of the coating, the air barrier is positioned approximately 0.15 inch from the disk substrate surface and prior to spin-off, the barrier is moved to a position 0.025 inch from the coated  surface.   Further, during the high speed spin-off cycle a high kinematic viscosity gas, such as helium, is introduced into the space between the barrier and the coated surface to establish a laminar flow condition and eliminate spoking of the coated material.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is disclosed for lining pipe section with a rigid tubular liner of synthetic polymer by pulling the liner through diameter-reducing rollers adjusted so that the resultant outside diameter of the liner while under a diameter-reducing stress is sufficiently smaller than the inside diameter of the pipe section that the liner may be readily drawn through the pipe section under diameter-reducing stress, and releasing the stress on the liner, thus allowing the liner to expand into contact with the inside wall of the pipe section.  The rollers are driven at a rate sufficient to maintain the tensile stress on the pipe liner below the tensile yield limit of the polymer.
