Title: Method for distillation of crude oil in hydrogen atmosphere and hydrogenative desulfurization treatment of crude oil
Inventor: KUNO MASAYA
IPC: C10G53/00
Filed: 1981-06-01
Abstract: PURPOSE: To carry out the fractional distillation and desulfurization of crude oil, economically, by increasing the pressure of a crude oil after the pretreatment such as  desalination, and separating a light fraction having desired boiling point while carrying  out the hydrogenative desulfurization in a distillation column in hydrogen atmosphere  under high temperature and pressure, thereby preventing the entrainment of the heavy  oil and facilitating the desulfurization.  
     CONSTITUTION: The pressure of a crude oil 1 is increased to a preset level after the pretreatment such as desulfurization, and the oil is mixed with hydrogen 2. The mixture  is heated in the heating device 3 to 388°C, and introduced into a high-temperature and  pressure distillation column 4 furnished with 9-stages of trays. Hydrogen 5 for stripping is introduced through the bottom of the column, and at the same time, a part of  the distillate 7 condensed with the column-top cooler 6 placed at the top of the column  is recycled to the column top to increase the distillation effect, and the crude oil is  separated into the light oil fraction 8 having a desired true boiling point between 340°C  and 525°C and the heavy oil fraction 9. The light oil fraction is transferred to the desulfurization apparatus, desulfurized in the presence of a sufficient amount of accompanied hydrogen, and separated by the purifying apparatus to obtain the product.

Title: End cutter of packing roll
Inventor: KOBAYASHI HIROSHI
IPC: B65B69/00
Filed: 1992-03-04
Abstract: PURPOSE:To secure the end packing material of a packing roll as well as to cut and remove it promptly by installing a cutter pressing device for supporting and shifting a cutter supporter so as to have both first and second cutters pressed to an end face of the packing roll. CONSTITUTION:A packing roll 1 is held on a roll supporting and turning gear, and both first and second cutters 11, 12 are pressed to the end face by a cutter pressing device 24. In this state, the packing roll is rotated in a direction heading for a serrated blade of the first cutter as reciprocating these first and second cutters in each blade direction through a cutter supporter 14. If so, the serrated blade cuts out an end packing material of the packing roll, and these first and second cutters get into the inside of the end packing material 2 together. Next, if the packing roll is rotated in reverse in the state intact, a straight blade of the second cutter is cutting a part adjoined to an end packing material 4 this time. In this state, the packing roll 1 is rotated, thereby cutting off the whole circumference of the end packing material in this way.

Abstract: PURPOSE:To obtain the socket part of a desired shape certainly, even though the heating temperature of a plastic pipe is low, by blocking the pipe end of the plastic pipe with a pipe end blocking member provided to slide freely on a second mold and evacuating to a vacuum, pulling out it. CONSTITUTION:After the diameter of the rising part 1a of a first mold 1 is expanded until it is protruded by a predetermined height to an outer peripheral face of a second mold 2 and a pipe end blocking member 5 is approached to the rising part 1a of the mold 1, a pipe end of a preheated plastic pipe P is fitted in the mold 1 until a predetermined length of a pipe end part P'a comes out to the mold 2 side.

A diameter of the end part P'a is contracted due to an action of a sucking force and the end part P'a is contacted to the rising part 1a and the mold 2 when the blocking member 5 is pulled out from the pipe P. Then, a socket part Pa being water-cooled, solidified, the diameter of the mold 1 being contracted and the pipe end blocking member 5 being moved to a guide 3 side, the plastic pipe P is pushed out from a forming mold.

Title: Cable protected from rat
Inventor: ABE AKIRA
IPC: H01B3/42
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To provide an electric cable permanently protected from rats, prevent corrosion of the cable, make the cable light weight, and reduce the cost of the cable by forming a polyacetal resin layer in the outer circumference of a cable wire core comprising a prescribed number of insulated core wires and forming an outer coating layer whose thickness is thinned at prescribed intervals on the outer circumference of the polyacetal resin layer. SOLUTION: A prescribed number of insulated core wires 1 respectively constituted of a conductor 1a and an insulator 1b are twisted, an intermediate layer 2 is formed on the outer circumference, and a binder tape 3 is rolled on the circumference of the resultant body to give a cable core 7. A polyacetal resin layer 4 having 1.0 mm thickness is formed on the outer circumference of the cable core 7 by extrusion molding and an outer coating layer 5 is formed further on the circumference. The outer coating layer 5 has thin parts 6 with elliptical shapes and formed at prescribed intervals. Consequently, based on the biting behaviour of rats, front teeth of a rat are hooked in the thin parts 6 and the front teeth are butted against the polyacetal resin layer 4 but cannot tear the resin layer and biting of the layer by rats is thus prevented.

IPC: B65G65/46
Filed: 1978-07-08
Abstract: PURPOSE: To simplify the cleaning of stuck dust on both sides of crossing paddles in a paddle conveyer by doubling the rate of rotation of one shaft in parallel shafts.  
     CONSTITUTION: The rotation rate between shafts 2 and 3 provided in parallel in trough is set in two to one. Paddles 4 and 4 are provided on the shaft 2 symmetrically with an angle less than 60 degrees to the axis, while on the shaft 3 similarly as on the shaft 2, paddles 5, 5, 5, and 5 are provided symmetrically with an angle less than 60 degrees to the axis. These paddles 4 and 5 are projected on lines crossed at right angles to parallel shafts 2 and 3, and constructed to keep the minimum gaps when two paddles are crossed by rotations of shafts. Consequently, even if powder bodies and the like promoted in viscosity by moistening and so on are stuck to the paddles, powder bodies on both sides of the paddles can be scraped and cleaned by each other because of the different rate of rotation between the shafts.
