Patent NO-20180761-A1 (NO)
Inventor: HEM GREGORY L
IPC: E21B29/06
Filed: 2018-06-04
Abstract: A watermelon mill has a cutting structure mounted on a removable sleeve. The mandrel can be in two pieces threaded together to trap a ring or lug extending internally from the sleeve. Alternatively the sleeve can serve as a coupling holding together opposed threaded components that then make up the mandrel. The mandrel can have a radial external shoulder to act as a sleeve travel stop and another sleeve can be pushed into the first sleeve that has the cutting structure on it for proper axial fixation. The second sleeve that does not have cutting structure is pushed into position by making up an adjacent pin and box combination at a nearby connection to the cutting structure. What results is a flexible assembly that assembles without welding and retains greater flexibility in the larger sizes due to the assembly method. The sleeve can be tossed when the cutting structure is spent or redressed and remounted for another use.

Filed: 1994-01-21
Abstract: A supply of absorbent panty liner pads formed by a contiguous longitudinal array of pad segments forming a strip. The strip has locally weakened zones to facilitate tearing off segments from the strip without the use of a cutting tool. Each pad segment is shorter than a standard panty liner pad so that approximately three segments are required to form a standard length pad. By tearing off two, three, four, or five segments in one piece, the user can create a panty liner having a short, standard, long or extra long length to suit her needs on any given day. The strip is wrapped upon itself into a roll so that pressure sensitive positioning adhesive strips are placed into contact with release surfaces formed on the strip, thereby protecting the adhesive prior to use without the need for release paper.

Title: Method of recovering ethylene glycol
Inventor: CRAFT FRANK S SR
IPC: C07C43/10
Filed: 1994-02-23
Abstract: The present invention is an improved process for the recovery of ethylene glycol from spent glycol generated in the manufacture of polyethylene terephthalate. The spent glycol typically consists of metal oxide catalyst residues, low molecular weight terephthalate oligomers, diethylene glycol and other trace impurities. The improved process of the present invention is based on the principle that elevating the temperature of the spent glycol increases the solubility of the low molecular weight oligomers so that the low molecular weight oligomers can be dissolved in the ethylene glycol and further that the spent glycol at an elevated temperature may be passed through an ion exchange bed to remove metal oxide catalysts, color forming impurities and other trace impurities.
