Title: Improvements in pressure indicators for fluid pressure engines and apparatus
IPC: G01L23/02
Filed: 1928-01-05
Abstract: 303,274. Arcus, C. R. Jan. 5, 1928. Steam, internal-combustion, and other fluidpressure engine indicators. - Comprises a particular construction of the type in which momentary communication is established between a gauge and the engine cylinder once in every cycle by the relative rotation of a pair of ported valve plates, one of which is rotated once per cycle from the engine while the other is independently adjustable or driven at a lower speed. The casing a houses two valve discs band c of which the iormer is carried by a shaft d driven from the engine, for example the cam-shaft in the case of a four-stroke engine. The disc c is carried in a hollow shaft m the central passage o of which is connected by a passage n with a port g adapted to register with a port f in the valve disc b. The end of the shaft m away from the casing a is rotatably mounted in a header p communicating by a passage q with the engine. A normally closed inlet r permits the apparatus to be filled with liquid. The shaft m and disc c may be adjusted by a handwheel 2 through a worm gear z, x so that the parts f, g register at any particular point of the stroke so that a pressure gauge connected to the opening i may register the pressure at this point of the cycle. An indicating pointer w on the worm wheel indicates the setting. For six cylinder engines the pointer is connected to a strap which may be screwed to a sheave in one with the worm wheel at any one of six equidistant positions. In a modification fluid under engine pressure may be introduced directly to the casing a wherein the two valve members are separated by a disc having a ring of perforations with any one of which the part in the adjustable valve member may be made to register.

Abstract: PURPOSE:To improve the extent of durability by specifying each diameter of a metal tip and a center electrode point part, length of a diametral part and a distance between the tip and a metal core and the depth of penetration in an all-around welding. CONSTITUTION:In a center electrode 4, a core and a noble metal tip 5 are inset in a point face of a compound material 40 consisting of a heat resisting nickel alloyed base material 41 and a good conductive metal core 42 at an interval of within 0.5mm, and both fitted planes 5A are welded together by means of laser or electron beams. Here when a diameter and length of the tip 5 are set down to A and B, and a diameter of the point of the electrode 4 to C as well as length of this diametral part to D, respectively, they cane to 0.3<=A<=0.8mm, 1.2A<=B<=3A, 0.1<=1/2(C-A)<=0.5mm in terms of size. Likewise, when projection, length of the tip are set down to E, a distance between the tip 5 and the core to F and the depth of penetration between the tip 5 and the core 42 to G, respectively, their relations come to D<=(C-A)/2, E<=B/4, 0<=F<=0.5mm, A/5<=G<=A/2. In addition, if the tip 5 is made into a compound sintered body with iridium as the main body, low temperature is maintained thus any separation in a weld part is kept back, and durability is well improved.

Title: Ultrasonic wave humidifier
Inventor: TOMIOKA TOSHIICHI
IPC: F24F6/12
Filed: 1992-01-07
Abstract: PURPOSE:To prevent propagation of bacteria in humidifying water and to provide fungus resisting effect to the humidifying water by a method in which an ultrasonic wave humidifier has a water storing tank arranged under an atomizing chamber and a cylinder arranged between the water storing tank and a water supplying tank which contains ion-exchange resin, and is further provided between the water storing tank and the cylinder with a check member which checks reversed flow of water. CONSTITUTION:When sufficient volume of water is put into a water supplying tank 5, propagation of bacteria in the water supplying tank 5 is prohibited by the effect of fungus resisting agent of silver system which is mixed by kneeding into a lid 15 which is in contact with the water. When a level of humidifying water goes down, the water from the water supplying tank 5 is supplied through a water supplying valve 6 to a cylinder 13 which contains ion- exchange resin 14. Here, calcium, magnesium and the like are removed from the water. Then, the water passing through a check valve, comes into contact with a resin block 17 from which it is given fungus resistance again. Then the water is supplied to an atomizing chamber, where it is atomized, and diffused out into a room. After a stop of operation of the humidifier, even if bacteria floating out of a diffuser 10 into the enviromental air flies into the atomizing chamber 7, the fungus resistance given to the humidifying water works to prohibit propagation of bacteria.
