Abstract: A refillable vertical foregrip spray device. The device has a weapon mounting interface (M LOK, Keymod, Picatinny) integral to the valve block. The hollow cylindrical portion contains the pressurized liquid or gaseous contents of the operator's choice. The valve block houses a push button release valve with a sliding safety mechanism and a charge valve for pressurizing the device. The weapon mounting interface is integral to the valve block. The device does not require the use of disposable aerosol containers. When not weapon mounted the device can also be freely carried and the user can effectively dispense liquid or gaseous contents of their choice.

Abstract: A shower jet generating device for a sanitary shower head has a jet disk that delimits a fluid chamber on the outlet side and has at least one jet disk opening. A fluid outlet element is disposed on the at least one jet disk opening and is movable in an axial main direction component, which element includes a movable valve body having a fluid outlet opening issuing from the fluid chamber. The fluid outlet opening is unblocked in an unblocking position of the fluid outlet element and is blocked in a blocking position of the fluid outlet element in response to a fluid pressure in the fluid chamber. The movable valve body cooperates with an unmovable valve seat which unblocks the fluid outlet opening in the unblocking position of the fluid outlet element and blocks it in a blocking position of the fluid outlet element.

Abstract: This emitter is constituted from an emitter body, a film, and a cover. The emitter has a water intake part, a discharge part, a first flow path, a second flow path, a flow reduction part, a flow path opening/closing part, a pressure-reducing flow path, and a bypass flow path. When the pressure of an irrigation liquid flowing through a tube is less than a first pressure, the irrigation liquid passes through the pressure-reducing flow path and the bypass flow path and is guided to the discharge part. When the pressure of the irrigation liquid flowing through the tube is equal to or greater than the first pressure, the second flow path is closed by the flow path opening/closing part, and the irrigation liquid taken in from the water intake part passes through the pressure-reducing flow path and is guided to the discharge part.

Abstract: A passive fire suppression system including at least one tapered cellular glass block and having a cap with a tapered shape disposed on the top of the at least one cellular glass block. The passive fire suppression system allows drainage from the upper surface to the bottom of the system. The drainage is beneficial for both environmental conditions such as rain as well as for incidents where combustible liquids are spilled on the top surface of the system. Therefore, the system will not only shield any combustible materials that are under the system but will also quickly drain any combustible liquids that may spill onto the top of the system to the lower surface.

Abstract: A system for the application of foamable chemical compositions is presented. The application system comprises an ergonomic handle/adapter removably attachable to a pressurized source of a foam product, the handle having inlet and outlet orifices or openings for flow of the foam product from the pressurized source to a nozzle, the nozzle having an outlet orifice for dispensing the foam product and an inlet orifice for connecting to a flexible tubular connecting member which interconnects the outlet orifice of the handle/adapter with the inlet orifice of the nozzle. The nozzle of the present invention includes design features to produce a fan shaped spray pattern of the foam product and to reduce the incidence of leakage or dripping of either moisture or the foam product at the nozzle's outlet. The tubular connecting member is flexible and therefore allows a user to spray foam into hard to reach places.
