  • Patent number: 6391198
    Abstract: An oil-water and oil emulsion separation system using a plurality of transport vessels as the separation tanks. The containers or tanks are arranged in series with sludge or oil removed first and thereafter remaining oil is removed and finally a relatively pure aqueous solution is returned to the system. The unit is useful with parts washers or any apparatus with which water is contaminated by free oil or sludge. A floating skimmer is placed in the user's sump and a vacuum draws this into a series of containers in which it is processed and in which sludge and oil are successively separated. A positive displacement pump is used. A manifold having vacuum relief valves for at least one container is also provided. In one embodiment, flow restrictors are placed in at least one manifold.

  • Patent number: 6354598
    Abstract: A wear sleeve for use with the active face of an associated seal unit. The wear sleeve includes a radial flange and an axial flange having a plurality of grooves therein. The grooves are formed on an inner margin of the blank while the blank is in a flat condition. Thereafter, the axial flange is drawn in a skirt forming die so as to create an outer surface on the axial flange having a hydrodynamic pattern thereon. The grooves are formed in a sinusoidal pattern, and the inner surface of the skirt forming die is free from formations creating interference with the skirt.

  • Patent number: 5913708
    Abstract: A method making a toy, doll, or mannequin wherein a relatively rigid core is covered with an elastic skin. The skin is bonded to the core in some areas but not others. This creates an expansible, variable volume pressurizable space between the core and the skin so that the skin may expand relative to the core to simulate weight gain or change of muscle tone. The method comprises selecting and/or treating the core so that only certain parts adhere to the skin-forming material, covering the core with a curable, skin-forming coating and allowing the material to form the skin that, after inflation, assumes a different size and/or shape than the core and thus simulates weight gain, change of muscle tone or other significant change of shape and appearance.

  • Patent number: 5834932
    Abstract: An electrical energy consumption measuring system is disclosed which includes a watthour meter, a meter socket, a set of voltage transformers and two plugs. The meter is energized when it is received within the meter socket. Selected socket terminals of the meter socket are electrically connected to one of the two plugs. The set of voltage transformers is electrically connected to the other of the two plugs. The system is constructed and arranged so that, when the plugs are matingly engaged, the set of voltage transformers electrically isolates the windings internal to the watthour meter from the service voltage of the power system.

  • Patent number: 5819629
    Abstract: A combination food article positioning device and slicing guide, primarily intended to assist in slicing buns or bagels. The bun or bagel is entrapped between the guide and a table or other horizontal surface and held in position by contact between an inner end face of a pocket formed in the body of the apparatus and a table or the like. The body also includes sidewall surfaces, some of which are circular portions and others of which taper toward an apex, such that the entire pocket has a "teardrop" configuration. The sidewalls are slotted to receive a knife, and the tapered sidewall segments preferably include serrations or teeth. the noncircular shape opposite the knife-receiving slot and the serrations prevent the food product from turning within the guide.

  • Patent number: 5776881
    Abstract: A treated solvent composition for washing mechanical parts or the like. The solvent contains not more than about 25% aromatic solvents with the balance being aliphatic and other non-aromatic solvents having a flashpoint of at least F. The solvent is treated with up to 10 parts of an additive composition selected from the group consisting of C.sub.14 and lower alcohols, diols, polyols, lower glycols, and lower glycol ethers and mixtures thereof. In use, finely dispersed contaminant particles settle from the body of the solvent more rapidly than in untreated solvent and the resulting clarified appearance enables the solvent to be used longer and more effectively in a cleaning operation.

  • Patent number: 5730444
    Abstract: A fluid seal including a casing unit and an elastomeric lip body portion. Frustoconical air and oil side surfaces of the lip body meet at an inner diameter portion to form a fluid seal band contacting an associated shaft in use. A continuous, circumferentially extending garter spring is embedded in the seal lip body. An axially inner surface of the lip body is defined in part by plural spaced apart ribs and the remainder is defined by pockets having portions lying closely adjacent the radially and axially innermost portions of the garter spring. In the free state of said seal, the garter spring exerts a radially inwardly directed preload force so as to resist radial expansion of said seal. The spring also resists dimensional shrinkage of the seal band and the remainder of the seal body.

  • Patent number: 5720308
    Abstract: A drain flow control assembly for liquids draining from a sink or the like to a reservoir having a given liquid level. The flow control assembly includes a downtube with its inlet opening above the level of the liquid and its outlet below the liquid level, a divider plate surrounding the outlet opening and extending radially outwardly of the opening a distance equal to at least twice the diameter of the downtube opening. The assembly also includes a radially smaller, imperforate deflector plate positioned beneath and spaced closely apart from the divider plate, so as to form a radially extending transfer space between the two plates. When the assembly is positioned in a liquid-containing reservoir with the downtube outlet below the upper surface of the liquid, liquid flows vertically through the downtube outlet opening and then horizontally through the radial transfer space.

  • Patent number: 5704189
    Abstract: A method of identifying and installing a plurality of electrical or other signal carriers, pipes, tubes or the like within a building structure. The method includes the steps of determining the paths along which the various carriers are to be laid out within the structure, formulating a retrievable record of such paths, storing and retaining the retrievable record of such location information in an accessible computer memory or the like, and assigning a unique identifying expression to each of the carriers. The unique identifying expression is reproduced on spaced apart portions of each of the carriers, and the carriers are then installed according to plan. By using the unique identifying expression to access the computer memory, the location of all points along each carrier can be determined.
