A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

A wheel mounted control assembly receives therethrough the tire valve stem from an air maintenance tire. A control assembly regulator controls a flow of air to and from a tire-mounted air pumping tube. The control assembly includes a bi-directional air distribution flow control system having multiple parallel air pathways, each air pathway coupled to a respective conduit connected to an air pumping tube mounted within a tire sidewall. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

A valve arrangement including: a valve inlet, a valve outlet arranged downstream of the valve inlet, a first chamber arranged directly downstream of the inlet, and a second chamber arranged between the first chamber and the valve outlet. The valve arrangement further includes a measuring nipple comprising a measuring channel for receiving a measuring device, and a closing arrangement having open positions and a closed position, wherein the closing arrangement in its closed position is configured to prevent fluid communication between the first chamber and the second chamber via the closing arrangement, and wherein the closing arrangement in its open positions is configured to allow for fluid communication between the first chamber and the second chamber via the closing arrangement.

A gas-fueled portable device for the thermal dispensing of volatile materials such as insect repellents is described. The device employs a pressure regulator to establish gas flow, heat generation, and dispensing temperature at pre-determined optimal values. The automatic operation at pre-determined settings provides simple on/off operation for the user of the device.

A sealing disk mounting assembly for a regulator includes a mounting member adapted to be operatively attached to a tubular member of a control member assembly of a regulator, a disk holder operatively attached to the mounting member, and an annular sealing disk disposed in an annular channel that is formed between the mounting member and the disk holder. The annular sealing disk is mechanically retained between the mounting member and the disk holder by compressive forces.

Gas flow control valve 3, wherein the gas flow control valve 3 comprises a housing 11 with a gas inlet 10, a valve seat 6 arranged in the housing 11, a valve body 5 assigned to the valve seat 6, wherein the valve body 5 is held by an upper spring and a lower spring and is centered by means of a diaphragm 26, and a gas outlet 12 which is positioned downstream of the valve body 5 and which is provided in the housing 11, wherein the valve body 5 is arranged in the valve seat 6 so as to be movable in a first movement direction 17 in order to form a controllable cross section of a passage opening 25 for the passage of gas, wherein a guide cage 15 positioned downstream of the valve seat 6 is formed in the housing 11, preferably on the valve seat 6 or on a spring receptacle, and a guide shaft 14 is formed on the valve body 5, wherein the guide shaft 14 is guided linearly in an opening direction of the valve in at least one section of the guide cage 15, and in particular comprises a damper 16 for the movement of the valve body 5.

Gas flow control valve 3, wherein the gas flow control valve 3 comprises a housing 11 with a gas inlet 10, a valve seat 6 arranged in the housing 11, a valve body 5 assigned to the valve seat 6, wherein the valve body 5 is held by an upper spring and a lower spring and is centered by means of a diaphragm 26, and a gas outlet 12 which is positioned downstream of the valve body 5 and which is provided in the housing 11, wherein the valve body 5 is arranged in the valve seat 6 so as to be movable in a first movement direction 17 in order to form a controllable cross section of a passage opening 25 for the passage of gas, wherein the gas flow control valve 3 comprises an adjustable diffuser 13.

A pressure reduction plant including two or more valve assemblies arranged in parallel and including: pressure reducers for fuel gas from the supply pressure to the delivery pressure; pilot valves to transmit a control pressure to the pressure reducers when the delivery pressure reaches the calibration value of the pilot valves; derivation conduits to transmit the delivery pressure to the pressure reducers, the pilot valves and the pressure reducer devices; command lines to transmit the control pressure from the pilot valves to the pressure reducers. One of the pilot valves is configured with a calibration value greater than the calibration value of all the remaining pilot valves and each command line is configured to communicate with a control line.

Valve for fluid and gaseous media, more particularly for regulating the pressure in pipelines, containing a housing of at least one upper and lower part, a pressure adjustment unit, wherein the pressure adjustment unit comprises a spindle, a spring plate, a spring holder and at least one spring, a cartridge, wherein the cartridge forms a function unit by means of which the function of the valve is defined, wherein the cartridge preferably contains an interior housing, a fastening means, a poppet and a diaphragm, wherein the diaphragm serves for dividing the housing into a medium-free and a medium-flowing area, wherein the cartridge is pre-fitted as a function unit and is disposed replaceably as a complete unit in the housing.

According to one embodiment a gas pressure regulator valve is provided that includes a valve body with an inlet gas conduit and an outlet gas conduit, a pressurized gas chamber into which the inlet gas flows after passing through a regulation valve and which is in fluid communication with the outlet gas conduit. The valve also includes a diaphragm having a central protuberance which houses a valve member. A closure cap closes the valve body. Adjusting means is provided for adjusting the regulated nominal pressure of the gas output from the regulator valve. An air chamber and the pressurized gas chamber are delimited in part by the diaphragm which is assembled and fixed between the valve body and the closure cap having the possibility of being axially displaced. The regulator valve further includes a rigid cover which covers the central protuberance, cooperating the cover with the closure cap in the event of an unexpected high pressure of the inlet gas to limit the displacement of the diaphragm.
