The present invention relates to an analysis apparatus for compressed gases in a compressed-gas tank, such as a breathing-air cylinder or the like, for determining gas components, in particular CO, CO.sub.2, O.sub.2, VOC, SO.sub.2, NO, NO.sub.2, helium and moisture, having a removal device which can be connected to the compressed-gas tank, characterised in that the removal device comprises a connection element which is under the pressure of the compressed gas to be analysed in the compressed-gas tank and can be coupled to a gas treatment device having a gas measuring and evaluating device for determining the desired gas components, the connection element is also pressurised when not connected to the compressed-gas tank, preferably by means of a shut-off valve, and the gas treatment device and the gas measuring and evaluating device are further also configured to monitor and analyse the compressed gases dispensed by a compressor to fill a compressed-gas tank.

An overpressure control apparatus is used to control jets of high-pressure fracking fluid or other stimulation fluid released from a treatment flowline in cases of overpressure. The apparatus includes a collection tank and one or more valves, which can all be mounted on or integrated to a skid. The sizes and weights of the collection tank and the skid may help to keep the apparatus on the ground during an overpressure event. The apparatus can be provided with an offline testing system that allows an operator to close off the communication between the apparatus and the treatment flowline, and instead, pump a clean fluid such as water at high-pressure to test the proper functioning of the valve.

A valve-device (VD) for a vehicle-braking-system (VBS), and a VBS. A VD for a VBS, having first/second control-units (CU), which are electrically connectable to the VD, which includes a valve-unit (VU) with an actuator for actuating the VU, a valve housing (VH) for the VU, and an error protection module (EPM) outside the VH. The EPM includes first/second supply-ports (SP) for electrical attachment to the first/second CUs, first/second main-ports (MP) for electrical attachment to the first/second CUs, a first connection port (CP) electrically connected to the first/second SPs, for electrical connection to the actuator, a second CP electrically connected to the first/second MPs, for electrical connection to the actuator, first and second electric protective circuits (EPC). The first EPC is electrically connected between the first/second SPs, and the first CP. The second EPC is electrically connected between the second CP and the first/second MPs. An EPC includes an electrical fuse-device and/or a diode-element connected in series to the respective supply/main ports.

A transmission hydraulic control system includes a manual valve, a default valve, and a clutch prime valve. The manual valve allows fluid flow from a pressurized line to a drive line when the manual valve is open (when a transmission is in drive or reverse). The manual valve prevents fluid flow from the pressurized line to the drive line when the manual valve is closed (when the transmission is in neutral or park). The clutch prime valve allows fluid to flow from the pressurized line to the drive line, and thereby bypass the manual valve, when the manual valve is closed and the clutch prime valve is open. The default valve allows fluid bypassing the manual valve to flow to prime a clutch of the transmission when the default valve is open. The clutch prime valve prevents fluid from bypassing the manual valve when the clutch prime valve is closed.

A vehicle system for a vehicle includes a controller. The controller is configured to transmit a first control signal to a transmission of the vehicle to engage a first gear of the transmission, acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle, and transmit a second control signal to the transmission to engage a second gear of the transmission based on the information.

A system of controlling the capture of emissions from an exhaust emitter includes a housing including an inlet, a first outlet, and a second outlet; an adapter configured to attach to the exhaust emitter and the inlet of the housing; an attachment assembly coupled to the exhaust emitter, the attachment assembly including at least one leg pivotably coupled to the adapter; at least one valve coupled to the housing; and a control unit capable of communicating with the at least one valve to control the emission of exhaust through the device.

A valve system having a valve with a moveable armature and a pneumatic actuation apparatus, a controller, a computer program product for simulating operating behavior of the valve system and an operating method for the valve system, wherein the valve is provided in an active operating state and a valve position to be approached is specified, a target differential pressure corresponding to the valve position to be approached that is to be set in the pneumatic actuation apparatus is determined, a differential pressure in the pneumatic actuation apparatus is changed and the differential pressure present is detected, and the differential pressure present is stabilized if a deviation between the differential pressure present and the target differential pressure falls below a settable threshold value in terms of amount.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.
