Abstract: An improved method and apparatus for continuously agglomerating solids of colloidal size of larger suspended in a liquid is disclosed. The process comprises passing the liquid between spaced electrode plates in the presence of a fluidized bed of conductive particles, and subjecting said liquid suspension to an electric field from alternating current applied across said electrodes through the conductive particles of said bed. The turbulence of the particles in said bed has been found to improve conductivity and current efficiency, minimize electrode erosion, and by a mechanical, scrubbing action of the bed particles, minimize fouling or scaling of the electrodes so that the suspending forces of said solids are rapidly and efficiently broken. The agglomerated solids may then be separated from the liquid by conventional means such as skimming, settling, flotation and the like.

Abstract: A new and improved insect trap utilizes one conventional light bulb in conjunction with a large transparent sheet or plate of Plexiglass or other suitable material of large surface area arranged to provide a light source causing insects to be attracted from both sides of such transparent plate having a large surface of area which obstructs the insects' flight path. This effectively attracts and entraps large numbers of flying insects causing them to strike the plate and be stunned and fall into an insect destroying liquid bath from both sides of the flight-obstructing transparent plate.

Abstract: The method includes the use of a conveyor table mounting press assemblies above and below the table respectively. Coils of connector plate stock having prepunched integrally extending teeth feed upper and lower press platens of the press assemblies, the platens being movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of a joint formed by a pair of wooden frame members disposed in end-to-end butting relation on the conveyor between the press assemblies. To join a pair of wooden members end to end in butting relation, the members are displaced forwardly along the conveyor table with the trailing member offset laterally from the leading member until the offset member butts a stop which locates the butt joint in accurate registration between the press platens. Clamp cylinders displace both members against a fence to longitudinally align the members.
