Abstract: An automatic fuel dispensing system including an automatic dispensing nozzle similar to dispensing nozzles which open manually to dispense liquids and shut-off automatically when tanks such as locomotive fuel tanks near the point of being filled, or for closing an automatic shut-off valve when the dispensing valve is a substantial distance from the tank being filled. The automatic dispensing system is provided with an atmospheric pressure balanced diaphragm and an internal vacuum conduit where the diaphragm operates the shut-off valve when reduced air pressure from the vacuum conduit interrupts the pressure balance of the diaphragm. The tank to be filled is provided with an air conduit connected to the internal vacuum conduit of the automatic dispensing nozzle to operate the cut-off of the nozzle to a point adjacent the outer opening of the tank fill pipe when fuel enters the air conduit.

Abstract: A method of continuously forming a mophead is disclosed for making a non-woven fabric mophead of a cellulose and synthetic resin fiber blend by sealing and cutting the non-woven fabric including:(a) combining a plurality of non-woven continuous fabric sheets together in a composite superimposed stack;(b) intermittently moving the superimposed stack to a sealing station and forming at least one ultrasonic seal transverse to the length of the sheet and in the center area of the superimposed stack;(c) intermittently moving the superimposed stack to a cutting station; and(d) dividing the superimposed stack into mophead widths and simultaneously cutting a saddle portion and plural strips.

Abstract: An automobile body frame straightening apparatus is disclosed which includes a stationary elevated ramp to support the automobile at a desired working height, body gripping supports to attach to the undercarriage of the automobile to hold it in a fixed position, and body frame pullers for connecting to a section of the frame or body to be straightened. The body gripping supports connect to the ramp by horizontally reciprocating hydraulic cylinders and beam to move along the sides of the ramp for alignment with the undercarriage of the automobile. Each body gripping support is vertically telescopic and horizontally extendable to align with the undercarriage of the automobile. A ground mounted rail is positioned under the ramp such that a foot element extending from the body gripping support can engage the rail for stability and travel. The body frame pullers are hydraulically operated and move in both the horizontal and vertical directions.

Abstract: A method for treatment of an organic material containing art object, such as a wood carving, a painting on wood or canvas, a textile hanging or a tooled leather saddle, for preservation and restoration thereof. The method includes the steps of partially impregnating the art object with an unsaturated resin and exposing the partially impregnated art object to a large dose of radiation to polymerize the resin, without addition of any catalysts and without the production of any significant exothermic reaction. The polymerized resin strengthens the art object and the radiation sterilizes the art object, destroying insects, molds, and other destructive biological vectors.

Abstract: This invention relates to a method of producing a high polymer composition for use in the manufacture of textiles which consist of an admixture of polyacrylonitrile and an aromatic polyamide.

Abstract: An analog to digital shaft position digitizer including a pair of driven members where one member with "fine" reference intelligence and increment intelligence thereon is driven at a higher speed than the other member with "coarse" reference intelligence and transfer command intelligence thereon. A photo-optic sensor system picks up the intelligence from the members and by an electronic gating circuit the "fine" and "coarse" reference intelligence pulses are sent to a digital counter to reset the counter while increment intelligence pulses are sent to a clocking line of the counter to provide parallel binary numbers. Transfer command intelligence pulses from the low speed member transfers the parallel binary numbers from the digital counter to an electronic latching circuit to indicate shaft angle displacement of a rotating shaft.

Abstract: The method of stiffening the ends for shirt collars or the liner therefore is achieved by first forming an elongated polyester stiffening element or stay to be attached to the collar or collar liner. At least one side of the stay is coated with a polyester heat fusible film. The stay is placed within the ends of the collar with the polyester film placed adjacent the material to which the stay is to be at least temporarily attached after which heat is applied at a pre-determined temperature and for a predetermined period, preferably by an electric heating element to the area adjacent the stay thereby softening the polyester film carried by the stay to a point of causing the polyester film to soften and adhere to the adjacent material. The method is carried out preferably by a semi-automatic machine shown and described herein. The stays are placed in a stack at each side of the machine from which a single stay is removed and placed in each end of the collar or liner as the case may be.

Abstract: There is disclosed a powder dispenser having a support for retaining an inverted opened rigid container of powdered material, such as powdered soap or detergent. The dispenser has a funnel-like arrangement terminating in a downwardly facing opening. Positioned thereunder is a trap chamber into which an amount of the powdered material is accumulated. The trap chamber is suitably journalled whereby it may rotate through a relatively small angle and also has a downwardly extending lever to manipulate the trap chamber whereby the powdered material therein may be discharged therefrom a leaf spring is provided to urge the trap chamber to its normal position to receive the powdered material.
