Abstract: Boron nitride, in its soft or "graphitic" form is utilized as a high-temperature lubricant in an oxidizing atmosphere. A particular application for the lubricant is on or in flexible, ceramic-fiber side seals on a continuous glass coating apparatus and the moving edges of glass itself, thereby minimizing any flow to or from the reactor of gaseous reactants.

Abstract: A device and method for forming a moving web of laminated composite material having weakened zones therein from a moving continuous web of relatively extensible plastic film material, having identical sets of graphics printed on nominally constant length repeat length portions thereof which are subject to length variation from a constant design repeat length distance, and a moving continuous web of relatively nonextensible paper material. A method and device for forming a three-layered composite material having weakened zones therein is also described. Carton blanks and liquid tight cartons having tear away tab portions formed from such three-layered composite material are also described.

Abstract: A method and apparatus for preparing a tissue block for sectioning in a microtome includes positioning the tissue block on a platform. A vacuum-retracted membrane of plastic film material is used to draw an underside of the tissue block or specimen into planar contact with the platform. The user adjusts any peripheral edges of the tissue block that are not properly oriented so the underside is in a planar position. The tissue block is frozen on the platform once it is properly oriented. The membrane is subsequently peeled away from the platform and O.C.T. compound is applied to the tissue blocks. The O.C.T. compound after hardening and the tissue block are transferred to a second platform carried by a mounting device such that the tissue underside is exposed. The tissue specimen is ready for sectioning as part of the Mohs fresh tissue surgical technique.

Abstract: Methods of bonding a printing plate on a base film and an apparatus therefor are disclosed. The apparatus includes a pair of support mechanisms, one of which is horizontally located and the other of which is disposed at a right angle with respect to the horizontal one. A strip of paper is reeved around the horizontal support mechanism, while a strip of film is reeved around the vertical one. A plotter is provided above and in conjunction with the horizontal support mechanism for marking the location on which to place a printing plate, on the paper reeved around the horizontal support mechanism. A half mirror is disposed in close proximity to both of said horizontal and vertical support mechanisms for projecting the location marked on the paper onto the film reeved around the vertical support mechanism. Using a lifter, the operator looks down the half mirror to view the location of a printing plate as projected onto the film, and bonds the printing plate to the base film in that projected location.

Abstract: Apparatus is provided for handling gasket-forming material. This material is usually supplied in tubular cartridge form and is dispensed to a screen with a porous pattern which shapes the material to the desired gasket-configuration. The material is spread on the screen and forced through to the other side where the gasket pattern is applied to an adjacent transfer surface of a transfer pad. This pad with the pattern on the transfer surface is moved to a mateable surface of a workpiece located on a support spaced from the screen. The gasket-forming material is then transferred to the mateable surface. The gasket-forming material is dispensed from the cartridge with the aid of a cartridge holder having an opening at one end to receive a spout of the cartridge and having a plunger at the other end with a plunger rod extending outwardly therefrom. A fluid-operated cylinder is aligned with the plunger rod and has a piston connected with the rod.

Abstract: Apparatus is provided for applying a bead of gasket-forming material to a mateable surface of a workpiece. The apparatus includes a source of gasket-forming material and a screen having a predetermined pattern conforming to the desired bead of the gasket-forming material. A spreader applies the gasket-forming material to one side of the screen and the gasket pattern is then formed on an adjacent transfer surface of a transfer pad on the opposite side of the screen. Means are provided for moving the pad with the pattern on the transfer surface and engaging it with the mateable surface of a workpiece mounted on a support spaced from the screen, thereby forming a bead of gasket-forming material on the mateable surface. The transfer surface is moved through an arc of 180.degree. when moving between the screen and the workpiece surface.

Abstract: Apparatus for manufacturing separator sleeves and/or pockets, for the reception of battery plates, seals the edge gaps of a sandwich of two separators and a plate with an extruded ribbon of plastics material. The sandwich is automatically assembled in an assembly section, from stacks of separators in separate magazines and a stack of plates in a further magazine. The assembled sandwich is fed to a sleeve-sealing section, with a conveyor which conveys the sandwich past extruders which seal the side edges. Water-cooled blocks cool and size the sealed edges, and rotary cutters under the control of sensors trim off excess plastics material extruded between successive sandwiches. At the end of the conveyor the sealed sleeves are fed on to a delivery table, if sleeve products are required, or passed on to a further conveyor of a pocket-sealing section if pockets are required.

Abstract: A moving, fibrous web is impregnated with a liquid by placing the liquid on the surface of the web, spreading the liquid over the web surface, pressuring a portion of the liquid into the web to partially saturate the web with the liquid and leave residual liquid on the web, and metering the residual liquid into a layer of substantially uniform thickness. This layer is then forced into the web to saturate it with liquid. This method is particularly effective for producing plastic pipe incorporating at least one layer of fibrous material saturated with liquid resin .Apparatus for practicing this method comprises a first surface transverse to the surface of the web, and a second surface converging with the web in the direction of travel of the web. The first surface performs the spreading step and the second surface performs the pressuring and metering steps.

The current-carrying core is placed inside the provisional sealed housing right after it is has been wound with the paper insulation tape.

Abstract: A pipe lining apparatus for lining pipe in situ with a fiberglas reinforced plastic. The apparatus includes guide rollers for holding the apparatus centrally of the liner in the pipe as the apparatus is drawn through the pipe. Rotating sprays apply a resin and a resin hardening catalyst to the interior surface of the lining and a rubber tube following the spray heads forces the resin and catalyst into the fiberglas of the liner. Rotating rollers then apply pressure to the liner to force the liner into intimate contact with the pipe being lined. A finish coat of resin mixed with wax covered with the catalyst is then sprayed on the liner.
