Abstract: The housing includes a horizontally disposed grate which is rigidly secured to a front frame plate, opposing side walls and rear wall, all welded together. A front access door is hingedly mounted on the front frame plate and a lock is provided to secure the two together. A coin/bill acceptor and a digital display are mounted on the access door and are electrically connected to a control circuit. A solenoid-actuated shut-off valve is interposed in a gas conduit between the burner and a propane or LPG tank coupling. The shut-off valve is responsive to the control circuit which receives inputs from the coin/bill acceptor and a flame detector and which also controls a flame igniter and the digital display.

Abstract: A measuring apparatus and method for measuring the length of elongated elastomeric articles, such as rubber hose, which has a slide table and one or two measuring wheels which contact the hose as it passes over the slide table. The wheels are connected to readout devices which visually display the measured length. The invention also comprises means for keeping the hose straight and means for controlling an arc effect in the hose as it is being measured. A method is described which explains a way to correct for stretch or shrinkage of the hose which tends to give false measurements. A method is offered on how to calibrate the apparatus.
