摘要： A bellows structure adapted to be connected between two parts of a fluid conduit system to serve as a flexible and expansible joint including a multi-ply bellows element having concentric inner and outer plies each of which is comprised of a flexible circumferentially corrugated thin-walled tube of fluid impervious material, the outer one of the plies having one or more ports therethrough communicating with space between the plies and adapted for connection therewith of means for monitoring or controlling fluid pressure or flow in the space, and spacer structure in the form of a fluid pervious screen-like meshwork positioned in the space between the plies affording passages for flow of fluid through the space to or from the port or ports.

摘要： Sealing cup centrally traversed by a conductor for use as a safeguard against the formation of overpressure and subpressure in electrical precipitation apparatus. The sealing cup substantially comprises a trough partially filled with a sealing liquid and having a plurality of annular chambers and a bellshaped member arranged to dip thereinto having a plurality of bell-shaped cylinders arranged so as to concentrically project into each of the annular chambers in the trough.

摘要： First and second volume chambers are connected to the fluid pressure system being monitored. Fluid from the system can flow to the chambers, but the fluid flow from the first of the chambers back to the system is restricted. Should the pressure differential between the system and the first chamber reach a predetermined amount, the second chamber is isolated from the system for a given period of time. If during this period of time the pressure differential between the second chamber and the system reaches a predetermined value, a signal is produced which signal may be used to actuate a device, such as a valve or warning signal.

摘要： The invention includes, for example, a special main line gas shutoff valve for the main burner of a gas furnace. The valve has two seats. Means are then provided to detect gas leakage into the space between seats. Preferably, a pressure switch is actuated to prevent main burner ignition if a gas leak is detected.

摘要： Apparatus for testing pipelines for leaks. The apparatus is passed through a pipeline by the flow of fluid. A hydrophone connected to the apparatus is in contact with the fluid and is sensitive to ultrasonic signals from the fluid arising from a leak. The ultrasonic signals appear on a recorder chart as a function of either the distance covered or a quantity related thereto. Pressure sensors are also attached to the apparatus, the signals of which can be for recording pressure indications as a function of either the distance covered or a quantity related thereto, and/or for actuating a switch device by which the recording equipment for ultrasonic signals can be partly or entirely switched off.

摘要： 1,086,479. Reducing loss of liquid from a closed vessel having a small leak. WACKERCHEMIE G.m.b.H. Nov. 25, 1965 [Nov. 27, 1964], No. 50159/65. Heading E1T. A method of preventing a liquid from running out of a closed vessel 1 that has developed a small leak comprises an air duct 3 leading from the top of the vessel to a reservoir disposed there-below. The vessel is also provided with a pressure gauge 7 to indicate the fact that a leak has developed, on filling duct 6 and on outlet pipe 4 having a check valve 5.
