Abstract: A gas-containing liquid generating apparatus according to an aspect of the present invention includes a gas/liquid mixing module configured to mix a gas and a liquid to generate a gas-containing liquid, a first injection module configured to inject the gas-containing liquid supplied from the gas/liquid mixing module, and a second injection module configured to inject the gas-containing liquid supplied from the first injection module to generate bubbles in the gas-containing liquid, wherein the first injection module includes a containing portion configured to contain the gas-containing liquid, a cylindrical portion having a channel configured to inject the gas-containing liquid into the containing portion, and a protruding portion provided on an inner wall surface of the cylindrical portion so as to protrude into the channel.

Abstract: A siphoning operation is controlled to meet a target flow rate of liquid being siphoned into a container having a headspace to which a vacuum is induced with an ejector. The incremental mass of liquid siphoned into the container is monitored and the vacuum applied to the container is continuously adjusted. A vacuum regulator responsive to an electric current-to-pressure converter which is coupled to a control unit is provided to control the flow of pressurized fluid delivered to the ejector.

Abstract: A water level control device including a cylindrical casing which has a bottom open end connected to a drain port of a water reservoir, a top open end, a plurality of longitudinally extended projecting rods spaced around its top open end, and a plurality of through holes spaced around the periphery at different elevations near its top open end; a socket mounted around the top open end of the cylindrical casing and defining a plurality of gaps through which water and air are allowed to pass from the water reservoir into the inside of the cylindrical casing; a hood covered around the socket and supported on the longitudinal projecting rods of the cylindrical casing, the hood defining a plurality of gaps through which water and air are allowed to pass from the water reservoir into the gaps defined within the socket, the hood having a downwardly extended bumper suspending in the top open end of the cylindrical casing; and a collar mounted within the top open end of the cylindrical casing at a lower elevation than

Abstract: An air induction control device for an internal combustion engine comprises means defining a communication passageway for communicating between air at atmospheric pressure and the air in the downstream passageway from a throttle valve. A valve member is disposed in the communciation passageway and is moveable toward the downstream direction thereof to open the communication passageway in response to an atmospheric pressure greater than pressure in the downstream passageway. A valve biasing means is disposed to apply force to and bias the valve member in the upstream direction to close the communication passageway in response to the pressure differential between atmospheric pressure and the air pressure in the downstream passageway. A flow restriction element positioned downstream of the valve member comprises calibrated openings defining a primary chamber and secondary chamber, wherein the volumetric proportion of the primary chamber:second chamber:calibrated openings is about 50-70:25-35:0.0-1.2.

Abstract: Disclosed is a heat accumulation tank system intended for use as a heat source of, for example, an air conditioner and which is installed, for example, in a building or under a green zone, a stadium or a parking area. The heat accumulation tank system is composed of a plurarity of water tanks which are connected through a communication passage such as a communication pipe. The pressure in the communication passage is controlled by means of a pressurizing device or a vacuum device, so that the state of communication is controlled such as to establish or interrupt the communication between the water tanks or to control the rate of flow of water between these water tanks.

Abstract: A process and apparatus for separating a volatile gas from a liquid in which it is dissolved. The liquid flows through a conduit having obstructions to cause separation by centripetal forces created as the liquid flows around the obstruction. The gases thus freed are collected on a surface disposed within the flow. The flow is advantageously through a syphon-like device thus reducing the pressure in the liquid to further assist separation.

Abstract: A device for diagnosing and monitoring urological diseases includes a determining unit for determining at least one characteristic of patient's urination such as a urine exit speed variation or a urine quantity variation over a period of time. Both characteristics can also be determined simultaneously by the unit. A urine receiving element for a patient and a characteristic recording element for a physician can be formed as separate units located remotely from one another.

Abstract: An automatic liquid delivery apparatus which employs no moving parts and requires no external source of energy except gravity to operate, dispenses liquid from a constantly available source, which is open to the atmosphere, to a receiver or zone requiring liquid in response to a detector which is located in the zone and initiates discharge of the liquid. The apparatus includes a valve device which retains liquid against discharge from a container or supply by air pressure confined in a space in a passage. The valve device delivers liquid through the passage when air in the space is released by a control device. The control device is a detecting mechanism or other automatic operating element. The detecting mechanism can sense the moisture level in soil, in liquid, in roots growing in moist air, in plant tissues or any other location where moisture differentials can be detected.

Abstract: A process for automatically providing for periodic surge flow or liquid slugs in the catalyst bed to insure that the catalyst is periodically fully wetted. Therefore, before dry spots develop in the bed and some catalyst particles are deprived of the liquid reactants, the aforesaid liquid pulse or slug will rewet the catalyst. This desired periodic introduction of a liquid slug through a catalyst bed is accomplished by the provision of a plurality of automatically actuating and operating siphon means disposed and distributed across the area of the distributor tray means within the reactor.
