Abstract: A method, of manufacturing a series of objects is disclosed. In the method, a layer of a manufacturing medium is provided. Portions of the layer of the medium, are bond together at at least edge regions of the layer to form a support portion. The support portion is lowered while gripping the support portion by the edge regions of the layer. A further layer of the medium is provided supported by the support portion. Portions of the further layer of the medium are selectively bound to form at least an object portion. An apparatus for performing the method is also disclosed.

Abstract: The invention relates to a flow cabinet system for cleaning at least one object, the system comprising: a cabinet having walls enclosing a volume; tubing for the supply of compressed gas as well as a plurality of handheld cleaning tools within the volume for removing, by means of the supplied compressed gas, powder from the at least one object; and an extraction unit comprising tubing for extracting powder-laden gas from the volume through a gas outlet located near one of the left and right side walls and the back wall. The cabinet further comprises a gas inlet in the back wall near the other of the left and right side walls and the back wall so as to define an overall flow that is substantially horizontal and transverse to the operator.

Abstract: A fitting assembly and method for attaching to a fluid flow conduit in which a clamp having a threaded port is secured around the conduit. A threaded bushing is inserted into the threaded port and has an axial bore that guides and supports a tool which is inserted through the bore to pierce the corresponding surface of the conduit. After the tool and the bushing are removed from the threaded port, an external component, such as a sensing unit, can be connected to the port to permit access to the fluid for sensing a flow characteristic of the fluid, or the like.

Abstract: A system and method for recovering a gasoline vapor/air mixture from a vehicle tank during the dispensing of gasoline from a storage tank into the vehicle tank in which the mixture flows from the vehicle tank to the storage tank during the dispensing of the gasoline. A sensor is provided which detects a property of the mixture which corresponds to the vapor content of the mixture. The flow of the mixture is controlled in response to the vapor content of the mixture.

Abstract: A gasoline vapor recovery system and method in which a flow metering unit is provided for measuring the flow of a mixture of air and gasoline vapor from a vehicle tank and for determining the density of the gasoline vapor in the mixture. A value is provided for varying the flow of the mixture from the tank, and a control unit is operatively connected to the flow metering unit and to the valve for adjusting the position of the valve, and therefore the flow of the mixture from the tank, in response to the density of the gasoline vapor in the mixture and the gasoline flow.

Abstract: A system and method for recovering a gasoline vapor/air mixture from a vehicle tank during the dispensing of gasoline from a storage tank into the vehicle tank in which the flow of the mixture from the vehicle tank to the storage tank is induced during the dispensing of the gasoline. The amount of oxygen in the mixture is sensed and the flow of the mixture is shut off when the oxygen content in the mixture attains a predetermined value.

Abstract: A fluid control apparatus and method in which a valve unit having a plurality of inlets is respectively connected to multiple fluid sources and an outlet. A unit containing a flowmeter is also provided which cooperates with the valve unit in a manner so that, upon rotation of one of the units relative to the other, the flow of fluid is controlled from the selected fluid source to the valve unit outlet. The flowmeter is adapted to measure variations in the flow rate of the fluid, and the flow of the fluid is controlled in response to one or more related parameters.

Abstract: A gasoline vapor recovery system and method in which a mixture of air and gasoline vapor is passed from a vehicle tank to a storage tank during the dispensing of gasoline from the storage tank to the vehicle tank. A portion of the mixture of air and gasoline vapor is vented from the storage tank, the flow and/or the vapor concentration of the vented mixture from the storage tank are determined, and the mixture flow from the vehicle tank is varied accordingly.
