    Abstract: Heat treating apparatus which includes a heat treating furnace, a chute at the back of the furnace, and a quench bath at the bottom of the chute. The chute has at least one opening in it located at a level above the quench bath, through which a purging gas is injected, and at a slightly higher level the chute has at least one opening in it through which purging gas, furnace atmosphere gas, quench bath fumes and other contaminants are exhausted. Also included is a method of heat treating objects utilizing the apparatus.

    Abstract: A method of maintaining the percentage of water in a molten salt solution substantially constant. The method includes the step adding water to a body of molten salt in response to a rise in the electrical resistivity of the solution beyond a certain predetermined value, and continuing the addition until the electrical resistivity falls back to the predetermined value.

    Abstract: Heat-treating apparatus which includes a controlled atmosphere heat-treating furnace whose exit is closed to the external atmosphere, a conveyor for delivering objects to be treated to the furnace entrance, and a hood covering the conveyor and surrounding the furnace entrance, the entrance of the hood being located at a level equal to or below the floor of the heating chamber of the furnace. Controlled atmosphere gas leaving the furnace entrance is channeled into the hood and is burned therein, thus preheating objects on the conveyor and creating a positive pressure inside the furnace.

    Abstract: A guard structure for a conveyor including link chains secured to side edges of a conveyor web, each chain being made up of pivotally connected plates which act as side guards for the web. The plates overlap each other, but are constructed to prevent the formation of gaps at the side edges of the web through which articles could drop from the web.
