Abstract: A sorbent particulate material, such as a metal hydroxide-coated sawdust, is made by passing a direct electric current between an anode of a metal capable of forming a flocculent hydroxide and a cathode in a turbulent electrolyte containing the dispersed particulate material, so as to form a metal hydroxide and deposit it on such material. Also described are filters made from the sorbent particulate material and processes of filtering or otherwise removing undesired components from liquid media by means of such product.

Abstract: A device to detect and control electrical potential polarities between two or more adjacent insulated conductor sections is disclosed. An amplifying circuit monitors the relative state of the polarities of the adjacent conductor sections and actuates a relay to change the same if a difference is sensed. The sensing function of the amplifying circuit is controlled by a switch member.

Abstract: A machine is described for partially slicing or perforating baked goods such as muffins, buns, and the like, whereby the muffin is either perforated or cut, but not entirely, to facilitate handling in production operations and to provide a sliced or perforated product, as demanded by consumers, that will adhere together until the muffin is ready to be broken apart prior to toasting or eating. The pre-sliced or perforated muffin is produced by automatically guiding the muffins from a production conveyor line into either a series of blades for making the perforations or into a cutting wheel for pre-slicing which can be adjusted to pre-slice the muffins to form a uniform top and bottom section thereof and a uniform depth of cut predetermined to provide a desirable size lip on one end of the muffin to hold the top and bottom sections together.

Preferably the display holder is made of a pair of three dimensional film plastic forms, made by vacuum forming of sheet materials, which are held together, the scene is that of a tooth, representing a castle, and includes as parts of the scene means for holding a toothbrush, tube of toothpaste and dispenser, of dental floss, all of which represent decay fighters or weapons used to protect against tooth decay.

Abstract: An extracting tool for removing a lug from an electronic part includes a pair of handle members, a gripping member and a ram, with the handle members being so related to the gripping member that on squeezing of the handles, jaws of the gripping member and of one of the handle members grip the lug of a condenser and on further squeezing of the handles a lever joined to the other of the handles moves the ram, which is mounted adjacent to one of the jaws, against the condenser, thereby causing relative motion of the condenser and the lug and extracting the lug from the condenser. Also described is a method for replacing an electrolytic can type condenser by detaching the lugs therefrom without detaching the electrical connections to the lugs and then soldering the lugs of a replacement condenser to said connected lugs.

Abstract: A casket, such as a readily assemblable knock-down casket, has side and end panels which are held together, to form an enclosure, by a plurality of metal straps in tensions, crimped together to form continuous belts, located interiorly of the enclosure. The straps pull together the side and end panels into abutting relationships at the corners of the casket, making the enclosure, which, together with a base and a cover, forms the casket. Usually the crimped metal straps, under tension, pull inwardly a plurality of corner clips which hold the sides and ends together by pressing them inwardly into abutments when the clips are pulled inwardly by tightening of the tension straps, which pass through interior openings in the clips. Similar straps may hold together the side and end wall sections of casket covers. Additionally, there are described ornamental corner clips which have the exterior surfaces thereof ornamentally or decoratively formed or covered.

Abstract: Silver is electrolytically recovered from photographic solutons, such as spent hypo, by feeding such a solution to a precollecting or measuring vessel where the solution collects until a predetermined volume has been received, at which time it is automatically dispensed, by a self-triggering siphon, into an electrolysis chamber of larger volume than the pre-collecting vessel and direct current is automatically turned on for a predetermined flow between an anode and a cathode in the chamber to plate out the silver on the cathode. An agitator, preferably a magnetic agitator, is also automatically energized to keep the solution homogeneously mixed during electrolysis, for maximum silver recovery efficiency.

Abstract: An apparatus for in situ preparing and applying foam to a surface, such as a roof, and at the same time applying a membrane onto the surface of the foam, produces a foam-membrane sandwich having an upper surface of controlled smoothness and thickness or pitch, which sandwich is firmly held to the treated surface. The apparatus is normally self-propelled and may be automatically controlled so as to be advanced across the surface to be coated with membrane-covered rigid polymeric foam, preferably of polyurethane foam, as the curing pre-foam and covering membrane are applied. In preferred embodiments of the invention the membrane is a roofing felt or fiberglass web, mat, treated paper or cloth fed from the apparatus from a roll thereon, producing with the roof or other surface to be coated, a form into which a curing pre-foam is deposited as the apparatus is advanced.

Abstract: A buoyant ram motor comprising a hollow buoyant ram element movable within a housing into which liquid such as water is admitted in a manner applying a buoyant force to the ram and moving or lifting it up along the interior of the housing. After each power stroke, the liquid is removed from the housing to lower or return the ram to an initial or starting position for the next power stroke. The liquid for moving the ram can be obtained from natural water bodies. The force applied to the ram during each power stroke is augmented by providing a vacuum in the housing on and exposed to the surface of the ram opposite the surface to which the buoyant force is applied. During each return stroke, liquid is removed from beneath the ram in a manner preserving the vacuum over the ram. This is accomplished by an arrangement including a chamber communicating with the liquid below the ram and containing a weighted cylinder supported on a flexible container filled with compressed air.
