Title: Output control method of welding power source
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/067
Filed: 1984-10-17
Abstract: PURPOSE:To prevent the defects in a shield and bead shapes by changing an arc voltage and current with detecting the omen of a short circuit in the welding method repeating alternately a short circuit and arc between a consumable electrode and welding base metal. CONSTITUTION:A welding is performed with alternately repeating a short circuit and arc between an electrode and base metal by feeding a consumable electrode to the welding base material. The omen of a short circuit is detected at the arc generation time of this arc welding method. The set value of the arc current or voltage is then lowered while this detecting signal is outputted or for the prescribed term. It is then returned to the normal setting again when the generation of the signal is stopped or after the prescribed term.

Abstract: PROBLEM TO BE SOLVED: To make it possible to prolong durability without occurrence of clogging, etc., with lapse of time by uniformly dispersing, agitating and mixing various kinds of transported base stock by a kneading operation analogous to a kneading by hand and surely delivering the mixture from a front end nozzle. SOLUTION: At the time of connecting and linking unit tubes 22 made of wear resistant elastic materials, such as urethane rubber, to a prescribed number of stages into a casing 11', expanded parts 23 are formed at both end faces 26, 26 of the respective unit tubes 22, 22. Flat constricting parts 24 are formed between these two end faces 26 and 26 and the expanded parts 23, 23 of the adjacent unit tubes 22, 22 are connected at a 90 deg. phase difference by means of positioning pins 30. Flowing slurries are expanded with each other in the constricted parts and the expanded parts. The kneading by the uniform dispersing, mixing and agitating is surely executed in this flowing process. As a result, the construction is simplified and the change of the material quality is averted.  The as-designed kneading is executed with high accuracy, so there is substantially no need for maintenance, inspection and service. The cost reduction is thus enabled.

Title: Evaporative separation of oil and water
Inventor: SHIOMI YUTAKA
IPC: C02F1/04
Filed: 1984-10-18
Abstract: PURPOSE:To separate easily water from oil by introducing high-temp. waste combustion gas, which is introduced from a waste gas pipeline, into an evaporator, heating a liq. mixture of oil and water to evaporate the water, returning the generated steam into the waste gas pipeline, and discharging concd. oil from the evaporator. CONSTITUTION:High-temp. combustion gas, which is introduced from a waste gas pipeline 4, is introduced into an evaporator 1 to heat a liq. mixture of oil and water and to evaporate the water, generated steam is returned to the waste gas pipeline 4, and concd. oil is discharged from the evaporator 1. Since oil is thus separated from water, water is easily separated from oil, even when a surfactant is mixed in the untreated liq. and emulsified and the separation is difficult by the conventional gravity separation. In this case, the evaporated surfactant is not mixed into steam, because the surfactant does not have any appreciable vapor pressure.
