This invention relates to a method and system for increasing the utilization of the supply of acetylene from two acetylene sources. The flow is provided at a substantially constant delivery pressure to a point of use, such as a customer point of use. A portable apparatus is configured to operably connect to each of the two acetylene sources simultaneously and during operation automatically provide flow from one of the acetylene sources through various valving and piping assembled onto the portable apparatus followed by supply to a customer point of use.

An apparatus for use with a robot may couple to or form part of an appendage, for example a wrist. The apparatus can include a base, a first platform, a second platform, a first set of linear actuators that moveably couple the first platform to the base and a second set of linear actuators that moveably couple the second platform to the first platform. The apparatus can take the form of dual prismatic platforms. A controller can provide control signals to operate the linear actuators to cause the first platform to translate and rotate with respect to the base and to cause the second platform to translate and rotate with respect to the first platform. Connectors can couple the base to an appendage and couple an end effector to the second platform.

Method and air treatment device (1) for control of supply air flow (L1). The air treatment device (1) comprises a chilled beam (2) with a pressure box (5) comprising an inlet (6) for inflow of supply air flow (L1) and a plurality of outlets (7) for outflow of the supply air flow (L1) out of the pressure box (5). The air treatment device (1) comprises an actuator (12) for control of supply air flow (L1), and the pressure box (5) comprises at least one pressure measuring socket (13) for control of static pressure (ps). The air treatment device (1) registers the static pressure (ps) and the position of the actuator (12), and calculates the real supply air flow (L1). The actuator (12) is arranged to change the configuration of the outlets (7) by a linear motion of a cover member (9) and change the open area of the outlets (7).

A FIR filter includes segment cells, each of which is configurable as an interpolation filter, a decimation filter, a symmetric filter, or an asymmetric filter. Two or more of the segment cells are configurable to be cascaded to form an interpolation filter, a decimation filter, a symmetric filter, an asymmetric filter, a complex symmetric filter, or a complex asymmetric filter. The FIR filter includes registers corresponding to the segment cells for storing coefficient values of the corresponding segment cells. The FIR filter further includes control circuits corresponding to the segment cells for generating control signals.

A valve control apparatus controls a valve for adjusting a pressure of a reaction gas supplied to a fuel cell. The valve control apparatus includes: an estimation portion that estimates a valve effective cross-sectional area of the valve; and an opening adjustment portion that adjusts opening degree of the valve with control amount corrected based on the valve effective cross-sectional area estimated by the estimation portion.

A pressure regulating valve includes: a body, including: a process surface; at least one inlet orifice in the process surface; In outlet orifices disposed in the process surface separate from the at least one inlet orifice; a resilient shut-off seal positioned in the process surface, defining a closed perimeter surrounding the at least one inlet orifice and separating the at least one inlet orifice from the plurality of outlet orifices; an inlet port communicating with the at least one inlet orifice; and an outlet port communicating with the plurality of outlet orifices; a reference housing; and a diaphragm constrained between the body and the reference housing, and arranged such that, when a reference pressure is higher than a process pressure the diaphragm is engaged with the outlet orifices, and when the process pressure is higher than the reference pressure, the diaphragm is disengaged from at least one outlet orifice.

An embodiment for ameliorating reusable packaging for cognitive commerce shipments is provided. The embodiment may include receiving information relating to a product to be shipped in a reusable package and historical sensor data obtained from a knowledge corpus. The embodiment may also include predicting a size of the reusable package in which to ship the product. The embodiment may further include identifying a required level of inflation of an array of balloons in the reusable package. The embodiment may also include inflating a plurality of balloons in the array of balloons consistent with the required level of inflation. The embodiment may further include in response to determining the product does not require additional protection, deflating each inflated balloon in the array of balloons upon delivery of the product to the final destination.

A gas regulator includes a valve chamber body that houses two valves of the regulator. Valve elements that move to open and close the two valves are received via a same opening into the valve chamber body, which is closed by a plug. The plug can define a first valve seat as well as a piercing element used to pierce a compressed gas cylinder. A retainer can hold a gasket at a valve seat as well as provide a bore or other support for a valve element and valve element spring.

Blocking device for pressurized gas pipelines includes: a blocking valve, which includes: a connection body; a movable shutter; a stem carrying the shutter; a fluid-dynamic actuator, configured to translate the stem; thrust means to bring the shutter from an operating position of opening to an operating position of complete closure; a control system for controlled actuation of the fluid-dynamic actuator, having a by-pass group for equalizing upstream pressures in an upstream chamber and downstream pressures in a downstream chamber, and a pressure reducer group interconnected with the bypass group, the pressure reducer group configured to receive a motorization fluid at a supply pressure as input, and to supply the fluid-dynamic actuator with a motorization pressure through a motorization line, the control system having a pressure differential selector that detects a signal of the upstream pressure and a signal of the supply pressure.
