摘要： A pipe repair bypass apparatus which enables residual water in pipes to flow without touching the area of the pipe to be repaired by soldering, is disclosed. The bypass apparatus includes a flexible disc slightly greater in its outer diameter than the inner diameter of the pipe to be repaired. The disc has a central opening which receives one end of elongated flexible tubing. A rigid tube is slideably arranged on the flexible tubing and serves to aid in inserting the disc and flexible tubing into the pipe to be repaired. When the apparatus is disposed inside a pipe, the disc acts as a dam for any water in the pipe with the water eventually flowing through the flexible tubing thereby avoiding the repair area.

摘要： An automobile hitch coupler aid is provided for hitching together two vehicles wherein the complementary coupling members are not easily brought into exact registration. The device comprises a female hollow pyramidal member having structure for mounting this member on one of the vehicles with a male pyramidal member having an outer surface substantially complementary to the inner surface of the female pyramidal member adapted to move between a closely nested position in the female member and a separated position which permits movement of the male pyramidal member relative to the female pyramidal member in any direction. To manipulate the two pyramidal members, a flexible member such as a chain or cable has one end fixed to the narrower end of the male pyramidal member and which then passes outwardly through the narrower end of the female pyramidal member and a device preferably carried on the outer wall of the female pyramidal member is connected with the other end of the flexible member for winding up and paying out the flexible member in operation of the device.
