Abstract:
A portable extendable inclined boiler having an open and a closed end, for steaming and thereby softening wooden members for later bending including: a low water cutoff utilizing a thermostat mounted on the boiler wall near the heater; a low water cutoff actuated by the reduction in weight of boiler heater to a predetermined minimum; a steam control thermostat mounted at the open end of the boiler which temporarily turns off the heater when excess steam is being produced; and an integral boiler water measure utilizing a weep hole in the wall of the boiler for providing an indication of the correct boiler water charge to the operator.
Abstract:
An apparatus for rapidly terminating of the flow of any fluid or particulate material through a conduit responsive to predefined dangerous conditions. A particular application will terminate fuel flow through a large fuel supply conduit in a racing vehicle responsive to a fire or accident or other dangerous condition. The apparatus includes a gas supply source that is opened responsive to actuation of the apparatus such that gas passes into a cylinder which moves to force a liquid to hydraulically expand an inflatable member which is operative to expand within the flow conduit to instantaneously terminate material flow therethrough.
