Abstract: An exhaust gas flow control valve for an internal combustion engine comprises a body, a diaphragm actuator and a bracket. The body is equipped with an exhaust passage and a valve member arranged in the exhaust passage. The bracket is equipped with an actuator mounting seat for mounting the diaphragm actuator and a body mounting seat connected to the body. The diaphragm actuator is equipped with a casing connected to the actuator mounting seat of the bracket, a diaphragm cased in the casing and a rod protruding from the diaphragm and out of the casing for actuating the valve member in accordance with the action of the diaphragm. Between the actuator mounting seat of the bracket and the diaphragm of the diaphragm actuator, moreover, there is formed an insulating layer for insulating the heat to be transferred to the diaphragm.
Abstract: A compressed air blowing apparatus for supplying compressed air to molding sand placed in a flask is arranged in such a manner that its compressed air reservoir tank is constituted by a surface-plate frame and a cover, the frame having a compressed-air outlet port which can be opened/closed by a sectioning device and a piston which can be vertically moved. The sectioning device is constituted by concentrically disposed large and small cylindrical members by a cover member secured to the large and small cylindrical members having air feed holes formed between the large cylindrical member and the small cylindrical member and by connecting duct for communicating the outside of the cylindrical member with the inside of the small cylindrical members.
Abstract: A method of manufacturing a wound dressing having microscopic web-like interconnections and a porous structure of continuous pores throughout the wound dressing. In the first embodiment of the method, the dressing is produced by the steps of heating while simultaneously stirring a biocompatible material and solvent to form a homogenous solution; cooling while simultaneously stirring the homogenous solution to form a gel made of a dispersion of gel particles of the biocompatible material and freeze-drying the gel.

Abstract: The present invention relates to a method of cleaning the outer circumferential surface of a drum by spraying a cleaning fluid thereon and a device for cleaning drums. The cleaning fluid is circulated and is cleaned with a filter during circulation. The drum is cleaned with a cleaning fluid passed through a primary filter having a porous structure at high pressure, after which the drum is cleaned with a cleaning fluid passed through a finishing filter having a fine porous structure. A device for cleaning drums switches a circulating passage for cleaning fluid so that the cleaning fluid can pass through the primary filter at high pressure to spray on the outer circumferential surface of the drum. Also, the device allows the cleaning fluid to pass through the finishing filter at low pressure to spray on the outer circumferential surface.

Abstract: This invention relates to a method of annoucing a low level of the remaining liquid in a dropper. According to the present invention, two electrodes are attached to the outer surface of a dropper, and a pulse of a stable level is applied to one of these electrodes. The remaining quantity of the liquid in the dropper can be detected automatically with ease by utilizing the variations of the electrostatic capacity occurring between these two electrodes. An annunciator is activated when it receives a signal representative of a low level of the liquid in the dropper, to inform a nurse of the necessity of replacing the dropper.
