Abstract: A device for applying a coating to moving fibers is shown comprised of a cylindrical applicator rotating about its axis, a support frame for supporting the cylindrical applicator wherein said support frame contains a cylindrical opening running through the support frame for supporting the cylindrical applicator, a slot with an opening running from the slot to the cylindrical opening, an internal passageway in the support frame and a tubular connecting piece which fits partially in the internal passageway of the support frame for delivering the coating to the surface of the cylindrical applicator. It is critical that the diameter of the cylindrical applicator be only slightly less than the diameter of the cylindrical opening running through the support frame, thus restricting the amount of liquid coating that can be applied to the moving fiber. By placing the tubular connecting piece directly adjacent to the cylindrical applicator, no pool of coating is created.

The piston (27, 28) of each magnetic valve (13, 14) acting upon the rubber diaphragm (23, 24) has a very short stroke.

Abstract: An apparatus and method for high speed placement of labels onto containers by a continuous motion. The label stock is transferred to a rotary vacuum drum, carried by rotation of the vacuum drum to a glue application station and then to a label application station where the glue coated labels are wrapped onto containers. As the containers reach the labeling position they are already rotating so that their surfaces are moving at the same speed as the drum surface. The labeled containers are then discharged onto a conveyor where they are held against rotation and stabilized by a pair of parallel belt drives.Glue is imprinted onto each label by a roller with a patterned surface. The roller picks up glue as it rotates past a glue bar surface which emits glue from a tapered exit. The tapered configuration causes build up of suitable pressure so as to force the glue into the pattern on the glue roller. A downstream edge of the glue bar surface acts as a doctor to spread and wipe off excess glue.

Abstract: A tray is provided for dispensing and wetting pre-pasted wallpaper. The tray features a trough and a dispenser rod for holding a roll of wallpaper. The wallpaper can be extended to a desired length and cut directly from the dispenser rod. The cut wallpaper is then placed on a shelf adjacent to a trough containing a wetting agent. The wallpaper is passed under the shelf and through the trough being guided by a guide submersed in the trough to ensure proper wetting. The paper is then withdrawn from the trough and hung on the desired surface.

Abstract: A labeling machine employing a turrent with pairs of axially aligned chucks which are rotatable about their common axis, means to move each pair of chucks farther apart for entry and exit of containers; such machine also having a vacuum drum rotatable about an axis parallel to the turret axis and a roll on pad spaced from and concentric to the vacuum drum to confine each container released by the turret and to roll each container on the cylinder surface of the vacuum drum. The roll on pad may have a rearward (downstream) extension to contact the container and rotate them.

Abstract: A hand held and manually operable masking machine having a sheet material housing on which is rotatably supported a paper roll and a pair of adhesive tape rolls. One tape roll dispenses adhesive tape to overlap a portion of one edge of the paper roll with the other tape roll dispensing adhesive tape to overlap a portion of the opposite edge of the paper roll. The front edge of the housing is formed into a cutting blade which is to be manually used to cut through the paper roll once the desired extended length has been obtained with this cutting also occurring through the tape that is secured to the side edges to the paper roll.

Abstract: The device for spraying a coating on the internal faces of a vessel (2) for the transfer of molten metal such as a tundish comprises a spraying lance (3) secured to a carriage (4).The carriage (4) is capable of displacement in translational motion on a guide (6; 106) which extends in a first longitudinal or transverse direction (D; L) of the vessel (2) and which is in turn capable of translational motion on guiding means (7; 107) extending in a second direction (L; D) which is transverse with respect to direction (D; L) aforesaid. These guiding means (7; 107) are themselves mounted on a suppport (8, 12) which is capable of translational motion in the longitudinal direction (D).

Abstract: A doctor blade and baseplate are adjustable to define a desired gap therebetween. The doctor blade is fixed in position, gap adjustment being effected by movement of the baseplate. Initial setting-up and levelling are effected by turnbuckles moving a supporting bar. The base plate is slidable vertically on the supporting bar via a pin-and-slot connection. Fine gap adjustment during operation is by screw jacks connected between the supporting bar and the baseplate and operated by a common driveshaft.

Abstract: Circuitry including a first and second source of electrical energy provides a continuous supply of electrical energy to a volatile memory circuit utilized within an electrical apparatus. The circuitry includes an on and off switch and allows for the first source of electrical energy to be supplied to the volatile memory when the switch is both in an on and off position. The secondary source of electrical energy is only used to supply electrical energy to the volatile memory when the first souce of electrical energy is either inoperative or disconnected from the circuit. Such circuitry allows for conservation of power of the second source of electrical energy which in some electronic apparatus may include a lithium battery that may be relatively difficult to replace.

Abstract: A method and apparatus are disclosed for heat sealing two thermoplastic parts by clamping the parts together with a cooled clamp so that the edges of the parts are exposed and melting the edges together by contacting them with a hot seal head wherein a layer of a protective material is interposed between the hot seal head and the parts to be sealed.

Abstract: A thin sample on a surface such as a tissue specimen on a microscope slide is exposed to treatment liquid such as a stain, antibody of nucleic acid probe.

Abstract: In an electrostatic spray coating apparatus (10), liquid coating material is applied to a workpart inside of a spray booth (12). Alternating flows of liquid coating material, liquid solvent and air are conducted through various internal flow passages in a conduit (14) inside the spray booth. An electronic differentiator (24) is positioned adjacent a predetermined location along the conduit (14) and energized from an electrical source disposed outside of the spray booth (12) to differentiate between liquid and gas in the internal flow passage for nonintrusively detecting when the head of liquid flow reaches the predetermined location along the internal flow passage. This is accomplished by an electromagnetic field extending into the flow passage and sensing the changes in the electromagnetic field resulting from dielectric differences between liquid and gas in the flow passage.
