Abstract: A system for installing an elongated hollow handgrip over an elongated end portion of a golf club shaft is operable to apply a liquid adhesive to an interior surface portion of the hollow handgrip so as to produce a coating of adhesive thereon and then to apply the hollow handgrip with the adhesive coating applied on the interior surface portion thereof over the end portion of the golf club shaft. The liquid adhesive is applied by use of a probe capable of receiving the hollow handgrip over the probe. The probe has an elongated central passageway with an inlet for receiving a flow of liquid adhesive and an outlet for dispensing the liquid adhesive from the probe. Also, the probe has an annular groove in an exterior surface portion communicating with the passageway outlet for receiving liquid adhesive from the outlet and wiping the liquid adhesive onto the interior surface portion of the handgrip as it is being moved past the annular groove to removed from the handgrip from the probe.

Abstract: Apparatus for installing grips on golf club shafts includes a grip lubricating device and a golf club shaft lubricating device. The grip lubricating device utilizes a wick which wipes against an inner surface of a grip. The wick is wettable by a lubricant that is held in a container. The golf club shaft lubricating device utilizes an absorbent, sponge-like liner that wipes against an outer surface of one end of a golf club shaft. Control valves regulate flow of lubricant from the container so that a controlled amount of lubricant is applied to the inner surface of the grip and to the outer surface of the one end of the golf club shaft.

Abstract: A method of applying a liquid coating material to the inside of a tank(10) and performing a hydrostatic pressure test on the tank at the same time. The method is useable for applying a liquid vitreous enamel coating material to a water heater tank, to be subsequently dried and furnace heated to form a glazed enamel internal coating. Preferably the hydrostatic pressure test is performed by displacing coating material from a portion(68) of an accumulator(51) by pumping liquid into a flexible bladder(66) housed in the accumulator. Pressure from pump(76) is transmitted to the tank(10 by the liquid coating material and held for a prescribed time interval to prove tank integrity. The method avoids excessive shear, hence viscosity changes in thixotropic coating materials.

Abstract: To rehabilitate an internally corroded underground pipeline, excavations are made at its opposite ends to which launching and receiving pipe structures are then secured. Various pig member sets, with appropriate treatment fluids carried thereby, are air-driven through the entire length of the pipeline to successively acid clean, etch, and neutralize its interior surface. The interior pipeline surface is then thoroughly dried by flowing dehydrated air through the pipeline. Specially designed leading and trailing extruder pigs, with 100% solid, high viscosity, solvent-free epoxy coating material therebetween, are then air-driven through the pipeline to extrude a first protective coating layer onto its interior surface. The first layer is then dried with dehydrated air.

Abstract: A process for simultaneously lubricating the interior wall of a underground conduit, while by use of compressed air, placing in the conduit a cable along the entire length of the conduit. The cable is drawn through the conduit by a puller, or comparable device, which is connected to the head of the cable, and rests in the conduit in a substantially air tight relation. This puller transmits a traction force to draw the cable through the conduit. The internal surface of the conduit is lubricated substantially uniformly over the entire length as the puller travels along the conduit by means of a reservoir of lubricant of a variable volume. This reservoir is at the rear of the puller, but in front of the cable. The lubrication and placement of the cable is along the entire length of the conduit. The invention also concerns an apparatus for carrying this process.

Abstract: A method and apparatus of applying a coating to a substrate is provided. A liquid resin is introduced into a first region at a predetermined pressure. The liquid resin is maintained within a first pressure range in the first region. Next, the flow of the resin from the first region to a second region is controlled so as to bring the resin from the first pressure range to a second pressure range, the pressures in the second pressure range being lower than the pressures in the first pressure range. The liquid resin is then applied at a pressure within the second pressure range to the substrate at a third region adjacent the second region.

Abstract: The specification discloses an apparatus for making confectionary or other shell goods by the method of filling a mold with a desired media and then inverting the mold to drain the media from the mold while leaving the mold coated by a layer of the media, thereby forming a hollow shell inside the mold. The mold travels through the apparatus on a conveyor. A sliding table is used to provide a turning point which defines the mechanism by which the mold is inverted. The sliding table receiprocates back and forth between extended and retracted positions along the direction of travel of the conveyor so that the speed of inverting the mold can be increased as the sliding table is retracted or decreased as the sliding table is extended.

Abstract: Method for coating the inside surface of an elongated metal tubular body which includes placing a plurality of elongated pieces of coating metal into the bore of the tubular body in alignment with the axis thereof, to provide a constant amount of coating metal along the length of the bore. The coating metal melts below the melting point of the tubular body. The bore is freed of oxygen by evacuation or by purging with inert gas. The tubular body and the elongated pieces of coating metal within the bore are then rotated at a high rotational speed sufficient to distribute the elongated pieces against the bore surface while maintaining the constant amount of coating metal along the length of the bore. The rotating tubular body is then heated sufficiently to melt the coating metal pieces and insufficiently to melt the tubular body. Melted coating metal is spread about the bore surface by means of the centrifugal force imposed upon the melted coating metal by the continued rotation of the tubular body.

Abstract: A rotary workpiece treating apparatus is described particularly useful for depositing coating or adhesive materials within threaded fastener nuts. The device includes a continuously rotating turntable assembly having a plurality of workstation cylinders attached thereto. Installed within the cylinders are plungers having cam followers, which plungers move between a first and second position as the turntable assembly is rotated. A probe attached to the plunger is caused to enter within the internal bore of the nuts and release flowable material within the nut. The flow of such material is controlled by a valve stem protruding from the probe which is depressed against a stop surface when the probe is inserted within the nuts. A second clamping plunger within the cylinder clamps against the nut when the probe is being inserted, thereby positioning the nut and preventing flowable material from being deposited on the exterior surfaces of the nuts.

Abstract: The previously carried out internal coating of contact tubes not only required very much manual labor and was very time consuming, but it was also unsatisfactory in regard to adhesion of the contact liquid to the surface and homogenity of the catalyst. By the simultaneous action of heat on the liquid interface in the tubes during the lowering of the liquid level as well as by a specially suited apparatus for this purpose which operates according to the principle of communicating tubes there is provided the possibility of a good adhesion to the surface as well as the formation of a homogeneous layer at very little operating expense.
