Title: Floater for controlling specific gravity
Inventor: OOHASHI MIKIO
IPC: G01N9/14
Filed: 1982-02-22
Abstract: PURPOSE:To continuously monitor whether specific gravity exists in the control limit or not at an optional temperature without making it necessary to correct a temperature, by enclosing a liquid having the same quality as that of a liquid for controlling the specific gravity in the control limit, into an enclosed vessel prepared by a soft thin film of synthetic resin. CONSTITUTION:By use of a soft thin film 1 of synthetic resin, a floater containing a liquid is prepared in the film 1 which is formed spherically, for instance, so as to show a state of the same quality as a liquid whose contents 2 are controlled at the highest temperatue of control. As a matter of course, as for the film 1, a material which is not swollen, nor changed in quality, etc. is used. When this floater is put into a liquid to be controlled (a lead battery, etc.), as a temperature rises, the capacity increases in the same way as the liquid to be conrolled, and when a temperature drops, it is reduced, it is necessary to correct a temperature, and whether the liquid to be controlled is in a proper state showing a constant temperature and constant specific gravity or not can be monitored at all times. It can be executed by coloring the floater so that it can be discriminated from the liquid to be controlled, and only observing whether it sinks into the liuqid or floats, it is unnecessary to take out the liquid from the vessel, or to open and close the vessel cover, and the measurement can be executed safely and exactly.

Title: Controller for gas automatic combustion controller of heating apparatus and usage method thereof
Inventor: ANTON PAREKU
IPC: F23N3/08
Filed: 1994-02-25
Abstract: PURPOSE: To reduce amount of energy and realize operation with large efficiency and low pollutant emission even at partial capacity of a burner, by using a blower with adjustable rotational speed which is driven by a DC motor for air control mechanism, and controlling the DC motor in response to a control signal of a control unit operated by a controller. CONSTITUTION: Gas pressure PF of an inflammable fluid F is controlled based on air pressure PA supplied to a control valve V from the output of a blower G. A temperature controller R controls the revolution speed of a motor MG to control air pressure PA inside a connecting pipe VL. The blower G is given by the 39-V DC motor MG, and the controller R drives a control unit StG based on the sign of difference between a target and actual revolution speeds and/or its magnitude. The control unit itself generates a control signal SSt for controlling the revolution speed of the DC motor MG. As a result, a throttle valve for controlling air pressure can be eliminated.
