Abstract: A molten metal metering and transfer device for use with a molding machine and a bath for holding and heating molten metal includes an elongate container which is supported in the bath with one end extending out of the bath and the other extending into the bath. An entry port is formed in the side of the container to allow molten metal to flow into the container and an exit port is formed in the container adjacent the top and above the bath. A uniquely formed plunger seated in the container moves downward into the bath, then upward out of the bath, trapping a predetermined amount of molten metal above its top surface. The formation of the plunger facilitates flow of the molten metal out of the container when the plunger reaches the exit port.

Abstract: A sponge mop retainer is attached to the end of a handle with a sponge member removably secured within the retainer. The retainer keeps the sponge member from rolling out when the mop is in use by tending to adhere to a surface while it allows the sponge member to be removed when the sponge member is worn out or dirty. The sponge member has four opposed longitudinal slits, one on each of four opposed surfaces. The retainer has a top wall and two side walls with the bottom edges of the two side walls having flanges which project inwardly, substantially toward one another. The free edges of each of the flanges have enlargements, substantially along their length, of a greater thickness than the thickness of the flanges which are engaged in two of the opposed slits to oppose movement of the sponge member away from the retainer.

The second section may be a coextensive flap hingedly secured along one edge of the first section. The gaskets have means connected to the first sections removably to secure them to the oven surface to hold them in place between the oven and the door, while allowing them easily to be removed to replace them or to clean the oven.

Abstract: A method of and apparatus for toning an exposed electrophotographic member in a camera or other electrostatic imaging device which uses liquid toner comprising toner particles suspended in a dispersant.The method contemplates running the liquid toner into a chamber containing the photoconductive surface of the electrophotographic member and a metal plate parallel with one another and spaced apart as two boundaries of the chamber. During the toning operation, a low d.c. bias is applied across the chamber between the photoconductive surface and the plate of a polarity opposite to that characterizing the latent image such as to repel toner particles from the photoconductive surface, but the voltage of the bias is low enough not to affect increments of the surface which have substantial charge on them. The result is that said increments with very little charge are left with practically no adhering particles.
