The flow rate of molten aluminum through a trough is measured by damming off the trough and diverting the flow through the measuring tube of a magnetic flow meter having a diameter, and located at a level in the trough to create a head of molten aluminum sufficient to produce a flow through the tube which is within the operating range of the meter. The apparatus includes a pair of spaced apart dam members forming a cavity therebetween which is transversed by the measuring tube. The magnet of the flow meter is located in the cavity preferably in a housing through which cooling air is circulated. The electrodes are made of an electrically conductive material which is resistant to corrosion by the molten aluminum, preferably, titanium diboride. Spring biased tapered connections seal the measuring tube with the dam members which have peripheral seals to keep molten aluminum out of the cavity.

Recycling apparatus for receiving and crushing recyclable containers is provided comprising a frame and an enclosure. A manually operated rotatable carrier is associated with the enclosure and has at least one open pocket therein to receive a recyclable container. The apparatus also is provided with detector means to determine the presence of a container in the pocket. Means are provided to lock the rotatable carrier to substantially prevent rotation of the carrier unless a container has been inserted into the pocket. Releasing means are also provided to permit rotation in response to actuation by the detector means when a container has been inserted into the pocket. The container is eventually crushed after rotation of the carrier to carry a container inserted into the pocket to a crushing station.

An apparatus for the receipt of a recyclable container is disclosed. The apparatus includes a manually rotatable carrier having a container receiving station. The recyclable container is inserted into the receiving station where the presence or absence of a container having a metallic sidewall is determined prior to any movement apparent to the user. If the object inserted into the receiving station is determined to be a container having a metallic sidewall, rotation of the carrier for further processing of the recyclable container is permitted. The initial passive screening may include detecting the orientation of the container, detection for the type of metal sidewall, and may also include optical scanning of the container for reading a product code thereon.

A vacuum die-casting machine has a sprue cavity with sufficient depth facing the shot cylinder that the shot cylinder piston can easily crush with a pressure of less than 1000 psi the thin cylindrical shell of solidified metal which develops into the biscuit, and continue to advance after the die cavity becomes fried with molten metal to inject additional molten metal into the die cavity to make up for shrinkage porosity as the cast part cools. The runner through which the molten metal passes from the sprue cavity into the die cavity has generally spherical reservoirs adjacent circular gates to further assure the supply of the additional molten metal to make up for shrinkage in the part. In addition, the piston can be oil cooled steel to delay formation of the biscuit.

Apparatus is provided for the insertion of a recyclable container into a container receiving station in a manually operated rotatable carrier normally maintained in a non-rotatable condition; and for analysis and initial acceptance or rejection of the container for recycling without mechanical movement apparent to the user. The apparatus includes detecting means adjacent the receiving station to determine the presence of a container comprised of material acceptable for recycling and scanning means for reading code markings on the container. The information read from the code markings on the container may be recorded for subsequent use in determining amounts of deposits to be paid as well as sources of containers. Releasing means are provided for subsequently permitting movement of said rotatable carrier if said container comprises a material acceptable for recycling.

Apparatus is provided for receiving and processing used containers including an enclosure with a rotatable carrier having one or more container receiving stations therein. Means are provided for detecting the presence of a container inserted into the receiving station. Means are also provided for crushing a container accepted for processing by the apparatus comprising a fixed crushing jaw and a movable crushing jaw adapted for dual engagement with a container to provide two stages of crushing.

A method for adding alloying material to a molten metal media, such as molten aluminum, is disclosed. The method includes converting the alloying material into a spray of superheated alloy material and directing the spray into the molten metal media at a depth below the media's surface to enhance dissolution and dispersion of the alloying material in the molten media.

A method for converting low-density objects into a bale that is suitable for transportation and storage. A bale made in accordance with the method of the invention comprises a first compressed biscuit having a recessed groove; a second compressed biscuit adjacent the first biscuit and a strapping means inserted into the groove and extending circumferentially around the first and second biscuits. The invention is particularly useful for making bales of compressed biscuits from recycled aluminum containers.

Apparatus is provided for receiving and crushing containers consisting essentially of recyclable material comprising an enclosure having a manually operated rotatable carrier with one or more stations comprising pockets in the carrier to permit insertion of a container. Means are also provided to detect the presence of a container inserted into the pocket. Shock absorbing means are associated with the rotatable carrier to inhibit damage to the apparatus by rapid or jerking motions during rotation of the carrier to transport an inserted container to one or more subsequent stations for testing and eventual crushing of a container accepted for recycling.

A known "spark cup process" may be operated without the spark cup if the violent fluctuations in the melt surface with which the electric arc is struck are accommodated so as to allow the electric arc to be maintained substantially continuously. Controlling the dynamic profile of the melt surface without a spark cup allows continuous operation of the electric arc which generates enough plasma to permit addition of as much as 1000 lb/hr of a spray of superheated feed material to a flowing stream of melt which assimilates the feed material.
