Title: Method of producing liquid oxygen and*or liquid nitrogen and apparatus therefor
Inventor: ARAN SHIABOORUDO
IPC: F25J3/04
Filed: 1978-03-20
Abstract: Liquid oxygen and/or liquid nitrogen are made by removing carbon dioxide and water vapor from air, compressing the purified air in a re-cycle compressor and dividing the purified compressed air into first and second streams. Part of the first stream is expanded in a first expander and the refrigeration produced is used to cool both the first and second streams in a first heat exchanger. On leaving the first heat exchanger, the second stream is expanded in a second expander and the refrigeration produced is used to liquify at least part of the remainder of the first stream. The liquid stream is expanded and introduced into a fractionation column from which liquid nitrogen and/or liquid oxygen can be withdrawn. Expanded air from the first and second expanders is returned to the re-cycle compressor although part of the expanded air from the second expander is preferably introduced into the fractionation column. The invention is particularly suited to installations producing in excess of 100 tons of liquid per day and, at this size, preferred designs offer an estimated 51/2 to 9% power savings over the known prior art.

Title: Temperature detecting type liquid level meter
Inventor: ENDOU TADAYOSHI
IPC: G01F23/22
Filed: 1982-03-03
Abstract: PURPOSE:To enable the accurate detection of a liquid level without suppressing the downflow  of a liquid stream in any way, by constituting a detecting nozzle in a liquid level meter  applied to a highly viscous liquid such as heavy oil from inclined pipes with predetermined  angles free from horizontal parts. CONSTITUTION:A detecting nozzle 2 is constituted from an inclined pipe 5 with a desired  length protruded from the side surface of a container 1 so as to upwardly direct the leading  end 3 thereof forming a temp. detecting end 4 at a predetermined angle theta and a inclined  branched pipe 6 connected to the side surface of the container 1 corresponded to a place  slightly higher than the leading end 3 of said inclined pipe 5 from the proper intermediate  part of the inclined pipe 5 near to the leading end 3 thereof at a predetermined angle theta. The  predetermined angle theta is determined experimentally by the shape and the size of the container 1 and the viscosity of a liquid. For example, when the liquid in the container is gradually  fallen, the falling of the liquid in the inclined branch pipe 6 and the inclined pipe 5 of the  detecting nozzle 2 is initiated as the liquid level in the container 1 is fallen and, by the suction action caused by the falling of the liquid, the remaining of the liquid in the inclined  branch pipe 6 is not generated at all. As mentioned above, because the entire interior of the  detecting nozzle 2 is constituted from the inclined parts with predetermined angle theta, the  downflow of the liquid is not suppressed at all and accurate detection can be carried out  always.

Abstract: PURPOSE:To permit easy operation and to increase a casting speed by supporting belts by means of plural continuously provided hydrostatic bearings, and disposing plural rollers spaced from each other in the hydrostatic bearing parts. CONSTITUTION:A belt type continuous casting machine casts and takes out continuously a billet 66 by moving belts 35, 36 constituting the shell on the opposed long sides of a rectangular casting mold at approximately the same speed as the billet 66 to be formed.

Filed: 1981-03-10
Abstract: PURPOSE:To suppress noise reducing vibration of magnetic shielding by equalizing an average diameter and winding turns of two juxtaposed windings and thereby equalizing magnetic attraction forces created by leaking magnetic flux from the two windings. CONSTITUTION:A winding consists of a high voltage winding 1 and a low voltage winding 2 which are connected in series are juxtaposed by a winding without a core.

Inventor: MASAKI KAZUMI
IPC: H03K3/53
Filed: 1984-02-22
Abstract: PURPOSE:To obtain a device of energy saving type by connecting a negative voltage absorbing diode in parallel to a thyristor or a capacitor, in a circuit for generating a magnetic force line pulse by supplying a charge of the capacitor to a magnetic force line pulse generating coil. CONSTITUTION:A capacitor C is charged in advance through a resistance R from a power source B, and a thyristor SCR is turned on by a trigger from a low-frequency oscillator A, by which a current is made to flow to a magnetic force line pulse generating coil L, and a magnetic force line pulse is generated. To the thyristor SCR, a diode D is connected in the reverse direction, therefore, a negative voltage by a series resonance of the capacitor C and the magnetic force line pulse generating coil L is absorbed, and the potential of the capacitor C of the time when the pulse generation has been ended becomes zero potential, therefore, charging is started from the zero potential. Accordingly, a charging current of a small quantity will do, comparing with charging started from the negative potential in case when no diode D exists.
