Abstract: A system for a decentralized emergency lubrication system including a dispenser assembly, a pressure supply assembly, a gearbox assembly, and an electronic assembly. Self-contained packaged oil delivery dispensers that generate its own pressure supply independent of a pump. It is possible to design systems of these packaged oil delivery systems which are strategically placed in a gearbox housing to provide the optimal amount of lubrication during a loss of lubrication (LOL) event. The benefit of dispensers driven LoL solution is that the technology is decentralized in nature, meaning that the supply of pressure does not rely on a single pump or the plumbing of nozzles to a pump. Dispensers offer system redundancy as well as the option to place satellite units strategically mounted in a gearbox housing.

Abstract: A chamber that communicates with a viscous material reservoir has a flexible resilient diaphragm which forms an exterior wall thereof. An impact mechanism, which may comprise a solenoid actuated hammer, applies a predetermined momentum to the diaphragm for rapidly metering a predetermined minute blob of the viscous material from the chamber through a nozzle. The reservoir is pressurized with gas to force the viscous material into the chamber to refill the same. The chamber is heated to control the viscosity of the material. Dispensing rates in excess of four blobs per second can be achieved. Variations in the height of the nozzle from the surface of the workpiece are not critical to uniform rapid dispensing. An alternate embodiment eliminates the diaphragm and instead rapidly retracts a nozzle relative to a fluid feed conduit to eject very small blobs of viscous material. A strain gauge detects refill of the chamber inside the nozzle and sends a signal to control refill logic circuitry.

Abstract: A package for containing and dispensing a viscous product such as toothpaste. The package includes a cylindrical container with a perforate spider member across an end of the container, such end serving as a dispensing end. A generally rigid, hemispherical pumping member with a discharge spout is reciprocatingly affixed to the dispensing end of the container, and is connected to a rodlike member which slidingly extends through the spider member and through a follower piston which is originally spaced away from the container. The container is operated by the application of hand pressure against the pumping member to move it toward the follower piston, with the pumping member being biased toward its original position upon the removal of the hand pressure by flexible portions of the rodlike member which engage the perforate spider and which are distorted by the movement of the rodlike member through the perforate spider.

Abstract: The actuating lever of the dispenser has a rigid valve flap integral therewith which covers the spout outlet to close the same when the actuating lever is in its normal, undepressed position but which then lifts off the outlet to open the same when the lever is depressed in a pumping stroke. One embodiment employs a reciprocable pumping piston at one end of the dispenser body and a free-floating take-up piston at the opposite end of the body which responds to the evacuationof material within the pump chamber to take up the space otherwise occupied by the evacuated product. Another embodiment utilizes a pumping piston which starts at the lower end of the dispenser body and is progressively drawn up toward the opposite end during successive pumping strokes by a rod connected to the actuating lever.

Abstract: Apparatus for melting and pumping molten liquid material from a drum of material which is solid at room temperature and which includes a platen assembly having a top platen and a lower heating platen suspended from the top platen but movable vertically relative thereto. A flexible, expansible sealing element extends between the peripheral edges of the top platen and the lower heating platen so that when the platen assembly is lowered into the open top of a drum of solid material and contacts the top of the solid material, subsequent downward movement of the top platen is operable to move the top platen downwardly toward the heating platen and cause the expansible sealing element to expand radially outward into contact with the interior surface of the drum. When the platen assembly is lifted from the drum, the top platen moves away from the lower heating platen and thereby contracts the diameter of the expansible element so as to move it out of contact with the interior surface of the drum.

Abstract: An apparatus for unloading heat meltable material from a container including a vertically moveable platen assembly having a platen supported by a platen carriage. The weight of the platen assembly is trapped between a balance spring which urges the platen assembly upwardly and a pressure spring which exerts a downward pressure on the platen assembly. The springs are fixed about a motor driven lead screw retaining the balance spring against the platen assembly from below and a pressure adjusting nut retaining the pressure spring against the platen assembly from above. Descent of the lead screw without an equivalent movement by the platen assembly will cause a disequilibrium in spring tensions as the balance spring expands and the pressure spring compresses. A limiting switch restricts the amount the lead screw can move after platen contact with the heat meltable material prevents further platen carriage movement.

Abstract: A tapping lubricant dispenser apparatus is provided for use in numerically controlled automatic toolchanger machining systems to dispense tapping lubricant into a previously drilled hole before tapping. The tapping lubricant is usually a viscous tapping compound of the consistency of paste, grease or the like. The apparatus includes a toolholder of the type to fit into the machine spindle, a reservoir for a supply of lubricant--typically sufficient to run unattended for several complete cycles, e.g. at least one shift--and a reciprocating pump that dispenses the lubricant responsive to actuation by the numerical control system when the toolholder of this apparatus is fitted into the machine tool spindle. The reservoir reloads the pump after each dispensing action. The numerical control and toolchanger system is programmed to select the apparatus, put it in the spindle, align same with the hole to be tapped, and causes pump reciprocation and dispensing and then remove the apparatus from the spindle.

Abstract: Apparatus for dispensing high viscosity thermoplastic materials such as resins, sealants and hot melt adhesives from drums. The apparatus comprises a functional hollow cylinder vertically disposed with a screw extending through its length. The cylinder is attached to a movable platen which is positioned to enter the open container through the top and adapted to move downward to the container bottom. Heating means, for example, a serpentine heated coil is attached to the underside of the platen. In operation, the thermoplastic material in the container is melted or highly softened enabling the screw to "lift" the material in the upright cylinder to an opening or outlet provided in the upper portion of the cylinder.

Abstract: The present invention relates to a dispenser for pasty compositions having a bellows on the top, a piston which travels in the direction towards the nozzle, and a rod which connects the bellows to the piston in such a manner that there is an idle stroke between piston rod and bellows so that a certain quantity of the content of the container withdraws into the nozzle channel upon release of the bellows.

Abstract: A non-pulsating, non-throttling, vented pumping system is disclosed for continuously dispensing product from a container in a relatively non-pulsating stream or spray. The pumping system includes a pump for withdrawing product from a container and for pressurizing the product, a storage compartment for storing the product under pressure, an accumulator piston in the storage compartment acting under bias to maintain the pressure on the product, an outlet passage opened and closed by the accumulator piston, and a restricted orifice at the outlet passage through which the product is dispensed as a stream or spray. The restricted orifice allows only a portion of the product pressurized by the pump to escape during the pressure stroke of the pump, and the remainder of the product is stored in the product storage compartment to be released for maintaining the spray or stream when the pressurizing pump is acting on its intake stroke.
