Abstract: Apparatus for transporting and guiding a portable furnace to transfer molten material from the furnace to a die cast machine includes a platform which supports the furnace. The platform has wheels at one end and fixed legs at the other end. The wheels roll on rails secured to the floor which guide the platform to a predetermined position, and a stop locates the platform in the proper position. The furnace is placed on the platform when the platform is in an aisle adjacent the machine, and the platform is pushed into place by lifting the fixed legs and pushing the platform. After the operation of the machine, the furnace can be removed by pulling the platform into the aisle and lifting the furnace off of the platform. The furnace can then be moved to another platform to transfer molten material to another machine.

Abstract: An X-ray film marking device for selectively shielding X-ray film from X-rays so as to imprint identifying characters on the subsequently developed X-ray film. Lead indicia are supported by an X-ray transparent support sheet. The support sheet and therewith the indicia is releasably secured to any suitable structure between the X-ray source and film by a flexible pad having pressure-sensitive coatings of adhesive substances. A tab connected to the support sheet and of a predetermined color for easy association with a particular indicia allows for rapid removal of the marking device.
