A radial flow steam injection heater that injects a selected amount of steam into a product flow to heat the product flow. The steam injection heater includes a mixing tube that receives the product flow to be heated. The mixing tube includes a series of steam injection holes that are positioned within a steam chamber defined by the heater body. Pressurized steam within the steam chamber flows into the mixing tube in a direction transverse to the flow axis through the steam injection holes. A regulating member is selectively movable relative to the mixing tube to expose the steam injection holes to the steam chamber to control the amount of steam utilized to heat the product flow.

A drum deheader is adapted for use with a cylindrical drum having a sidewall, a cover at opposite ends of the sidewall and an annular chime joining each cover to the sidewall. A receiver is adapted to be positioned against the sidewall and is engaged with the chime. A slide plate assembly is adapted for vertical sliding movement within the receiver and carries a cutting blade adapted to engage the cover. An elongated handle is pivotally mounted to the receiver for operably moving the cutting blade upwardly and downwardly into and out of cutting engagement with the cover. The invention is improved by a follower and slot arrangement formed in the handle, the receiver and the slide plate for enabling the upward and downward movement of the cutting blade as the operating handle is pivotally moved.

A fiber drum chime removing system for disassembling fiber or paperboard drums having metal chimes has a stationary cutting assembly and a movable cutting assembly. The stationary cutting assembly cuts the upper edge of the fiber sidewall of the drum to remove the upper drum chime from the drum. Contemporaneously, the movable cutting assembly cuts the lower edge of the fiber sidewall of the drum. A chime cutter mounted to the movable cutting assembly then cuts the lower drum chime to remove from the drum. Air cylinders automatically engage the stationary and movable cutting assemblies, and electric DC motors automatically drive the cutting assemblies. The chime cutter is automatically actuated by an air cylinder. The position of the movable cutting assembly is also adjusted automatically with an air cylinder so that the movable cutting assembly can be located in the proper position for cutting engagement.

A liquid heating apparatus capable of using low pressure steam and having a temperature control system to automatically control the output temperature of a heated liquid. The apparatus includes a tubular housing having an internal annular seal, and a liquid nozzle, that is connected to a source of liquid to be heated, is mounted for axial movement in the housing relative to the seat. The annular space between the nozzle and the seat that defines an annular diverging passage which communicates with a source of steam under pressure. The steam is accelerated as it is discharged through the diverging passage into contact with the stream of liquid being discharged from the liquid nozzle. The liquid and steam then pass through a converging mixing chamber where the momentum energy of the steam transfers to the liquid as the steam condenses on the liquid. The mixture then passes into a diverging diffuser section and the heated liquid is discharged from the diffuser through a discharge conduit to a site of use. A power operated control mechanism is operably connected to the liquid nozzle for moving the nozzle within the housing to vary the cross sectional area of the steam outlet passage, and a temperature sensor is mounted in the discharge conduit for sensing the temperature of the discharged liquid and operating the control mechanism to regulate the input of steam to the aperture.
