Abstract: Disclosed is a method for treating a yarn end hanging down from a yarn package which is doffed by means of a doffing apparatus from the winding apparatus after completion of the package winding, and an apparatus for effecting the method.The disclosed apparatus comprises a peg for receiving a doffed full package, a supporting member for rotatably supporting the peg, which peg including a securing member therein for securing a full bobbin held thereon, and a rotating member for rotating the peg with the full bobbin secured by the securing member to the peg, the rotating direction of the peg selected to be a direction which is the same as the rotational direction of the bobbin on the winding apparatus.Utilizing this apparatus, a yarn end hanging down from the full bobbin can be wound back around the full bobbin.Yarn end entanglement, full bobbin damages and damages of the doffing apparatus caused by the yarn end hanging down from the full bobbin can be prevented from occurring.

Abstract: A portable pipe wrapping machine is provided wherein a pipe enveloping frame which is rotatably supported concentrically with respect to a pipe comprises a reel assembly that is mounted on the frame and that is adapted to receive and rotatably support a roll of wrapping material of the cold wrap type that has a separator sheet between adjoining plies of the roll in position for feeding wrapping material from the roll to the pipe to be wrapped about the pipe while rotating the frame about the pipe, a sheet receiving assembly being provided that is powered responsive to rotation of a roll of wrapping material comprised in the reel assembly, the pull-tension on the wrapping material as it is applied to the pipe being adjustable by adjustment of a friction brake and said sheet receiving assembly comprising a friction clutch that is adjustable to maintain the protector sheet under a predetermined pull-tension as it is stripped from said wrapping material and wound upon a windup spool.

Abstract: An intake manifold for a multicylinder internal combustion engine has a riser connectable to a carburetor and branch pipes connecting the riser and each suction port of respective cylinders of the engine, and is characterized by being provided with orifice means located at a position in each said branch pipe for defining the cross sectional area of the position to a preselected magnitude thereby rendering pressure in each said branch pipe and each said intake ports of the cylinder equal. The orifice means can be constituted by a plate-shaped gasket having orifices to be located in the positions in each said branch pipes.

Abstract: A numerical control comprising an input means for reading a program, a forward-interpolating-information producing circuit, a reverse-interpolating-information producing circuit, an interpolation circuit and a control circuit for controlling the above means is provided.

Abstract: A continuous mixing method and system for preparation of syrup employed as a starting material for continuously manufacturing plate products therefrom are disclosed. The syrup is prepared by a method in which at least one additive is incorporated into at least one master batch of methyl methacrylate or a monomer mixture of methyl methacrylate and a copolymerizable unsaturated compound or a syrup of a monomer-polymer mixture thereof and the flow of the resulting liquid mixture is continuously combined with the flow from another batch of a syrup of the monomer-polymer mixture in a proportion such that the master batch is less in amount than said other batch, and the combined flows are continuously blended with each other.

Abstract: An intimate, co-dried mixture of a major amount of tricalcium phosphate and a minor amount of locust bean gum is useful for the preparation of tablets by the direction compression technique. The mixture is blended with an active material and, if desired, fillers, disintegrating agents and lubricants, and the resulting blend is compressed without prior granulation or slugging to form a tablet containing at least about 10 weight per cent of the co-dried mixture.

Abstract: An intake manifold for a multicyclinder internal combustion engine has a riser connectable to a carburetor and branch pipes connecting the riser and each suction port of respective cylinders of the engine, and is characterized by being provided with orifice means located at a position in each said branch pipe for defining the cross sectional area of the position to a preselected magnitude thereby rendering pressure in each said branch pipe and each said intake ports of the cylinder equal. The orifice means can be constituted by a plate-shaped gasket having orifices to be located in the positions in each said branch pipes.
