Title: Central cleaner
Inventor: NAKATANI TADASHI
IPC: A47L5/38
Filed: 1991-03-07
Abstract: PURPOSE:To reduce wirings from the main body to each receptacle, and improve the property by eliminating the polarity of the wirings by a method wherein a circuit which is attached to a hose and through which a current flows from the power source of the main body to a junction wire is closed to control the amount of the flowing current. CONSTITUTION:When a hose 4 is inserted in receptacles 2a-2e, the terminal is connected by an electric cable 3, and a current flows from an A/C power source of the main body to a slide control on a local control unit. The strength of this current is controlled by the resistance. An IC determines timing of an output pulse by a D/C voltage for which the output of a current transformer is rectified. That is, it is detected that a commercial power source becomes exactly O voltage, by an input signal, and it is controlled in such a manner that after how many milliseconds from the O voltage, the output pulse is sent. The earlier the timing to send the pulse becomes, the larger the voltage to be applied to a fan motor becomes large on an average, and the rotational speed becomes faster.

IPC: F27D17/00
Filed: 1979-04-09
Abstract: PURPOSE:To accurately measure the fluctuating furnace port suction air amount by calculating the furnace port suction air amount from gas analysis data and waste gas flow rate, calculating skirt resistance from this air amount and in-furnace pressure and adding the correction corresponding to disturbances to this. CONSTITUTION:The data of a waste gas flow rate indicating recorder 14 and gas analyzer 15 are operated by an operator 16 to calculate the furnace port suction air amount. The effective skirt resistance is derived from this value and the infurnace pressure obtainable from the furnace pressure gauge 13 of that time, whereby the momentarily changing furnace port suction air amount is obtained. Beforehand, the correction amounts by disturbance elements are obtained empirically by disturbances such as the position of a skirt 4, the height of a lance 3, blowing oxygen flow rate, the time during slopping occurrence, etc. respectively. The correction is applied to the skirt resistance value by these data when disturbance elements occurred. Thereby, the furnace port suction air amount is measured relatively accurately at all times.
