Patent number: 4374165Abstract: A method and apparatus for applying liquid adhesive to a work-piece. A reservoir containing the liquid adhesive is moved relative to a stationary perforated support member immersed in the adhesive to expose the support member. Excess liquid adhesive drains through apertures in the support member. The work-piece is placed in contact with the support member for application of the adhesive thereto. After the work-piece is removed from the support member the reservoir is allowed to move back to again immerse the support member. The reservoir is preferably resiliently mounted and connected to a foot-treadle which when depressed moves the reservoir downwardly, exposing the support member.Type: GrantFiled: June 25, 1981Date of Patent: February 15, 1983Assignee: James L. Taylor Mfg. Co.Inventor: John L. Mortoly

Patent number: 4373569Abstract: A window shade roller adapted for mounting by frictional engagement within the periphery of a window frame, or alternatively, by hang-mounting at receiving brackets on the window frame. The roller has one shaft projecting from a recess in one end that terminates in a spring-loaded pintle to enable raising and lowering the shade, and a spring-loaded second shaft extending through a cap closing a recess in the other end of the roller also terminating in a mounting pintle. The second shaft is selectively movable between a first retracted position so that only the pintle projects through the cap enabling hang-mounting of the shade, and a second telescoped position in which the roller may be frictionally secured within the window frame by placing friction members over the pintles.Type: GrantFiled: October 6, 1980Date of Patent: February 15, 1983Inventor: Bernard Barettella

Patent number: 4367801Abstract: A load cell is disclosed, which is especially applicable for use with electronic counting and/or weighing scales and the like. The load cell comprises a parallelogram-type flexure frame, and is characterized by four strain gauges, which are located at the upper and lower surfaces of two vertically overlying corner flexure regions of the parallelogram. This arrangement--because of symmetry considerations--is uniquely free of second-order errors generated by offset loading on the weight-receiving platform via which the generally vertically-directed forces to be measured by the cell are applied. At the same time, the arrangement provides two corners completely free of strain gauges, providing sites which can be trimmed by filing or so forth to compensate for small symmetry errors present in the load cell as originally fabricated and assembled.Type: GrantFiled: April 22, 1981Date of Patent: January 11, 1983Assignee: Pennsylvania Scale CompanyInventor: James S. Bryan

Patent number: 4367579Abstract: A crystal plating device and method thereof in which a crystal to be plated and thereby set at a desired frequency is placed in an external removable holder or slug for insertion into a chamber of a plating device. The device is connected to a vacuum pump which is activated after the slug is loaded. Spring loaded filament posts carry a filament of precious metal such as gold or silver. The crystal is oscillated at a predetermined frequency prior to the filament being energized to evaporate or atomize the metal which plates the crystal and sets its frequency identical to that of the oscillator. The slug is externally loaded and can carry different size crystals. It is fitted with masks to accurately direct the deposit of the metal upon either or both sides of the crystal. After plating the slug is easily removed from the plating device.Type: GrantFiled: October 6, 1980Date of Patent: January 11, 1983Assignee: Emkay Manufacturing Co. Inc.Inventor: Alan Kaplan

Patent number: 4349966Abstract: A cutting guide includes an elongated wide flat base plate having ruled markings along one edge and a raised flange along the opposite edge. The raised edge serves as a linear guide for a cutting tool, such as a utility knife, while providing a protective barrier to prevent the sharp knife blade from slipping over the edge and causing injury to the user. A plurality of beveled feet along the lower surface of the base provide structural support and an improved gripping surface to prevent undesired movement during use. The wide base also facilitates holding the guide down firmly against the material being cut to permit steady and efficient operation.Type: GrantFiled: March 19, 1981Date of Patent: September 21, 1982Inventors: Michael J. Marino, Michael R. Marino

Patent number: 4343694Abstract: A method is disclosed for separating titaniferous and ferruginous discolorants from a crude kaolin clay. A dispersed aqueous slurry of the clay is formed containing a deflocculant and a fatty acid collecting agent, and the slurry is conditioned to coat the discolorants with the collecting agent to thereby render the discolorants hydrophobic. A system of sub-micron sized magnetic ferrite seeding particles, the surfaces of which have been rendered hydrophobic, is thereupon added to the slurry. The seeded slurry is mixed to coalesce the hydrophobic-surfaced discolorants with the hydrophobic-surfaced seeding particles, and the slurry is then subjected to a froth flotation, which removes substantial quantities of the discolorants and seeding particles coalesced therewith, and also removes excess seeding particles and excess collecting agent.Type: GrantFiled: August 25, 1980Date of Patent: August 10, 1982Assignee: Anglo-American Clays CorporationInventors: Jerry A. Cook, Gary L. Cobb

Patent number: 4340477Abstract: A vacuum sludge receiver comprises a large vessel having a plurality of flexible filter tubes or extractor elements disposed along the bottom of the vessel connected to a common manifold in turn connected to a source of vacuum. Sludge bearing liquid is pulled to the manifold. As the liquid is extracted, the sludge forms a cake around the elongated flexible extractor elements to seal the elements and prevent direct access of air to the elements thereby maintaining a vacuum in the elements to continue drawing liquid from those areas of the container in which the flexible elongated extractor elements are still immersed within the liquid. Upon extraction of the liquid to the desired extent, the entire sludge-containing vessel is rotated to allow the sludge to be physically removed.Type: GrantFiled: April 30, 1979Date of Patent: July 20, 1982Inventors: Russell B. Hobson, Jr., Roger B. Vannelli

Patent number: 4334985Abstract: A method is disclosed for beneficiating a kaolin clay pigment to improve the rheological properties of a high solids suspension subsequently formed therefrom. According to the method, a 10 to 20% solids aqueous suspension of a kaolin clay is subjected to a selective rheological separation, by mixing the suspension with from about 0.001% to 0.1% by weight of dry clay, of a high molecular weight anionic polymer, and allowing the thereby treated suspension to separate into a sedimented phase, and a supernatant phase which is substantially free of aggregates; and separating the supernatant phase containing the beneficiated kaolin pigment in suspension. The suspended product of the process can then be conventionally processed, as by reductive bleaching, floccing, filtering, washing, dispersing, and drying.Type: GrantFiled: December 15, 1980Date of Patent: June 15, 1982Assignee: Anglo-American Clays CorporationInventor: Ralph E. Turner, Jr.

Patent number: 4329227Abstract: The device is a hollow annular member bounding a liquid flow passageway. The member has a gas inlet and a row of apertures around the throat of the passageway to emit gas bubbles into the liquid to induce an upward flow of gasified liquid. The base of the hollow is weighted and the device is freely suspended by a line in the liquid. The suspending line passes freely through a horizontal tube suspension point effectively rigid with the member and a substantial distance above the member. This improves stability of the device against bodily movements and oscillations due to flow reactions, and enables level placement of the suspended device in a desired location.Type: GrantFiled: February 27, 1980Date of Patent: May 11, 1982Inventor: John J. Todd
