Inventor: LEE HAE MYUNG
IPC: E02D5/80
Filed: 1998-12-31
Abstract: PURPOSE: A nailing construction method is provided to remove and recycle a nail without obstructing other structure constructions. CONSTITUTION: A spiral bar(1) alternatively combines many sockets(2) and hollow pipes(3). A grout hose(9) is combined with a recessed groove in flanges(7,7') of the socket and inserted into a drilled hole(20). A space(11) among sockets, hollow pipes and hole is filled with grout(12) through the grout hose and grout is hardened to be nailing. The socket installs a stopper to prevent grout from inletting into the socket. After nailing, a nail is easily removed by rotating the spiral bar combined with the sockets and penetrated through the hollow pipe.

Date Aug. 7, 1997A process for the separation of propylene from an input stream of C3 hydrocarbons containing propylene and methyl acetylene and/or propadiene and, optionally, C4 and/or higher hydrocarbons is described. The process includes subjecting the input stream to fractional distillation to separate propylene as an overhead stream leaving a bottoms stream containing the methyl acetylene and/or propadiene and the C4 and/or higher hydrocarbons, when present. A propane-containing stream is added to said input stream whereby propane is separated as part of the bottoms stream. The propylene content of the bottoms streams is maintained at less than 10% weight. The amount of propane added to the input stream is such that the weight of propane, propylene, and C4 and/or higher hydrocarbons, when present, in the bottoms stream is greater that the total weight of methyl acetylene and propadiene in the bottoms stream.
