Abstract: PURPOSE:To obtain the desirable fluidity of kneaded material and accelerate early setting after placing as well as secure sufficient time for transportation at the time of transporting ultra-quick-setting cement concrete manufactured in a ready-mixed concrete manufacturing factory and quick-setting filler or self-leveling material into a construction object site for placing. CONSTITUTION:Cement kneaded material obtained by kneading cement, quick- setting material, a setting conditioner and water is transported into a construction object site first, and then a setting accelerator is added into the cement kneaded material, and further kneaded and placed. Since the setting conditioner is added and kneaded for the conditioning of the cement kneaded material, the setting of the obtained kneaded material is delayed so as to secure sufficient transportation time. Also, because of adding-kneading the setting accelerator at the time of field construction in addition to the quick-setting material already kneaded in the cement kneaded material, the fluidity of the kneaded material is desirable, and setting is accelerated effectively, resulting in quick setting and early manifestation of strength.

Title: Automatic speed control method with double-engine one-shaft type propeller
Inventor: MATSUMOTO HIROSHI
IPC: F02D29/02
Filed: 1985-06-20
Abstract: PURPOSE:To exercise a broad speed control, by using two engines of a double- engine one-shaft type separately, and expanding the scope of the total output without changing the output area of a single engine. CONSTITUTION:When a practical ship speed signal is larger than a setting ship speed signal, both engines E1 and E2 are controlled in the decelerating direction, and when the output comes to 40% of the rating speed, one side clutch K1 is cut off to stop the engine E1 while the output of the other engine E2 is controlled at 80%, to make no change before and after the converting. When the practical ship speed is smaller, the output of the engine E2 is increased, and when it comes up to 85%, the stopped engine E1 is driven automatically. And, the both engine E1 and E2 are controlled at a revolution of 42.5% output, and the clutch K1 is connected to convert to double-engine drive, without changing the output before and after the converting. Thus, a broad speed control can be exercised by expanding the total output 20% or more without changing the output of a single engine 40% or less.
