1. An electrode plate for storage batteries, especially lead-acid storage batteries, comprising a current collector which includes a collecting lug (1), a circumferential frame (21) and grid-shaped current collecting bars (11, 12) for forming grid fields (6) within the circumferential frame (21), comprising a plastics grid (2, 3, 4; 18, 19; 14, 16) anchored to the grid fields, and comprising armou...

In shutting down a combined power plant, a steam turbine is first shutdown while operation of a gas turbine at high load is being continued, and the steam generated in a waste heat recovery boiler is passed on to a condenser through a bypass system bypassing the steam turbine. The gas turbine is then shutdown when this condition prevails, and gland sections of the steam turbine receive a supply of...

PURPOSE:To stop external detection for runaway and to detect the possibility of a runaway internally by providing a means of monitoring a memory output to a data bus all the time in a processor, and detecting abnormality before a program runaway occurs. CONSTITUTION:The means of monitoring the memory output to the data bus at all time is provided in the processor to detect abnormality before the o...

Raw materials are reclaimed from magnetic tape scrap by cutting the scrap into small pieces; treating the cut scrap with aqueous alkali solution; stirring the alkali-treated scrap at high speed thereby completely separating them into tape substrate and magnetic powder; washing the scrap with water and draining it; stirring only the tape substrate fragments at high speed under vacuum and at a tempe...

The disclosure relates to a particulate agent based on free-flowing, pulverulent ammonium polyphosphate of the general formula H(n-M)+2(NH4)mPnO3n+1 in which n stands for a whole number with an average value of about 20 to 800 and the ratio of m/n is about 1. The agent reduces the ignitability of combustible substances and constists of (a) about 80 to 99.5 mass % ammonium polyphosphate and (b) abo...
