Title: Improvements in and relating to control devices operated by change of liquid level
IPC: F22D5/12
Filed: 1921-01-07
Abstract: 178,515. Trist, A. R. Jan. 7, 1921. Valves actuated by fluid under control of frangible devices.- A float-operated control device. for controlling the supply of liquid fuel to the burners of a boiler, comprises a float controlled by the changes of water level in the boiler for releasing a perforating-device, which pierces a diaphragm and so releases pressure fluid to operate a valve. A vessel a is connected to the boiler so that the float d remains floating at the normal water-level. The float is connected by a rod e to a pivoted support f carrying a weight g, so that when the float falls below a predetermined level the weight is allowed to fall into the chamber m. The falling weight strikes a plunger p, which pierces a diaphragm t and thus allows pressure fluid to pass downwards to operate a fuel-control valve z. If the apparatus is used on a marine boiler, the effect of movements of the ship on the water-level in the vessel a is counteracted by a slightly buoyant ball check valve w which tends to close against a sudden outflow of water. To set the device again when the liquid level is normal the diaphragm t is replaced and the weight g restored to its upper position; a guide surface m<1> is provided for this purpose. Undue oscillation of the float d is prevented by means of slack chains d<2> attached to a device d<3> at the bottom of the vessel a. The weight g may be replaced by a weighted lever or by a spring-pressed device.

Abstract: 1495661 Detecting undervoltage or voltage failure MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 8 Jan 1975 783/75 Heading H2K [Also in Division H3] A voltage-drop indicating circuit, which can be arranged to indicate either that a voltage source Vcc has failed but subsequently been restored or that the voltage of the source is currently below a threshold value, comprises a transistor 4 and load resistor 2 forming a series circuit across the source, and a negative resistance device 1 formed by two complementary f.e.t.'s (Fig. 1, not shown) and connected between the base of the transistor 4 and an intermediate point A in the series circuit. For detecting failure and subsequent restoration of the source, the load line of Fig. 4A is chosen, so that at the normal operating point (Vcc) no current flows, but following failure and restoration of the supply the device 1 stabilizes at the point P, causing the transistor 4 to conduct. For merely detecting fall in voltage below Vt 2  a slightly steeper load line is used (Fig. 4B, not shown). Conduction of the transistor 4 is indicated, e.g. by an LED 3 in the series circuit. A change-over or shorting switch 6 resets the circuit. The f.e.t.'s in the negative-resistance device 1 may be jugfets or igfets, and the transistor 4 may be replaced by a Darlington pair. A second transistor 8 may be switched off when the first transistor conducts thereby extinguishing a corresponding lamp 7. The circuit may be used to monitor the voltage supply of clocks or data processors
