  • Patent number: 4936072
    Abstract: A filler and sealer with an endless two directional flexing chain having carriers thereon are capable of being driven about vertical axes of a rotary filler and also about horizontal axes of end discs. Each carrier movably supports a tray supporting head which is accurately maintained in filling positions relative to rotary and reciprocating tray fillers, and is thereafter accurately maintained in position to have a lid sealed on the container. Arcuate guide shoes on each carrier ride in linear and arcuate tracks to guide the carriers. A push bar conveyor includes spacer rollers which engage each carrier and push the carriers around their paths of movement at uniform speed.

  • Patent number: 4934245
    Abstract: A spall backing material contiguously attached to an armor plate at least suppresses the formation of lethal armor spall from being propelled from the inner surface of the armor plate when the outer surface of the armor is impacted by a weapon with sufficient impact to release high velocity spall from unprotected armor. When the impedance of the spall suppression armor is equal to or greater than the impedance of the armor plate, the formation of lethal spall in the armor will be prevented. When the spall backing material is reduced in thickness to minimize weight and has an impedance lower than that of the armor plate, or a more powerful weapon is used, armor spallation will occur but will be suppressed by the spall backing material to minimize lethality.

  • Patent number: 4918627
    Abstract: A system is provided which operates to compare three-dimensional models of inspection gages constructed from computer aided design (CAD) data for a manufactured part and standard geometric dimension and tolerance call-outs to three-dimensional models constructed from inspection data obtained from the manufactured part. The comparison is made both graphically, to assist an operator, and mathematically to determine part condition. Parts are found to be either in tolerance or out of tolerance. If out of tolerance they are found to be either reworkable or scrap. Additionally, the system is capable of determining syntax correctness for tolerance standards, defining the sequence of steps for a specific job prior to job execution, performing individual part tolerance conformance analyses and statistical part tolerance analyses for a population of parts, tolerance analyses for mating parts, and generation of tolerance call-outs for fixed and floating fastener features on parts.

  • Patent number: 4903471
    Abstract: A variable force tree shaker is disclosed which includes a non-rotatable housing having a two-piece shaft journaled therein. A fixed weight is rigidly connected to the shaft and an adjustable weight is pivotally connected to the shaft. At least one hydraulic cylinder is formed in the fixed weight and receives a piston which is connected to the adjustable weight by a piston rod. While the shaft is driven, an hydraulic controller directs hydraulic fluid into said at least one piston which moves the adjustable weight between a balanced position diametrically opposed to the fixed weight providing no shaking forces to the shaft, and a plurality of unbalanced positions imparting shaking forces of different intensities to the shaft.

  • Patent number: 4872501
    Abstract: A tank for heating deicing fluid in a mobile aircraft deicer comprises a submerged heat exchanger coil through which heating fluid passes. Propellers near the heat exchanger circulate the bulk of deicing fluid while it is being heated to help distribute the heat. Pivoting shutters isolate an area beneath the heat exchanger from the bulk of deicer fluid and from which deicing fluid is withdrawn by a pump. This allows the bulk of deicer fluid to be further heated in a "last-pass" before being discharged upon the aircraft. A method of heating deicing fluid using this apparatus is also disclosed.

  • Patent number: 4867483
    Abstract: A pipe connector device for interconnecting first and second pipe elements using a retention member removably secured to the first pipe element by load elements. The retention member is secured to the second pipe element by pipe threads or a second retention member can be secured to the second pipe element by load elements and the first and second retention members threaded together. A seal is extended along a portion of the length of the first and second pipe elements adjacent to an end portion of each of the pipe elements to prevent leakage. This provides a fluid-tight seal which is relatively independent of any pressure exerted between the first and second pipe elements by the retention member.

  • Patent number: 4865104
    Abstract: A tire changer has the feature of therefor restraining vehicle tire/rim assemblies which are caused to explode due to tire overinflation or tire bead failure for any reason. A tire and rim assembly hold down bar is pivotally attached to one side of the body of the tire changer and is secured in position immediately overlying the tire/rim assembly on the tire changer by engaging a tongue in a buckle assembly mounted on the bar. The tongue is attached to the end of a web belt which is secured to the other side of the body of the tire changer. Engagement of the tongue in the buckle also actuates an enabling valve in a conduit for transmitting tire inflation air from a pressure source to the tire. Inflation air may then be provided at will to the tire by actuation of an inflation valve located in the air conduit between the pressure source and the tire.

  • Patent number: 4860633
    Abstract: An autoloading method and apparatus is disclosed for a turret mounted gun that is pivoted horizontally relative to the turret and must be lowered to a substantially horizontal 0.degree. position for loading selected cartridges from a magazine conveyor, ejecting empty cartridge cases and misfired cartridges from the gun and turret, assisting in replenishing cartridges from outside the turret into the magazine, and off-loading cartridges from the magazine. A partition divides the turret into two compartments with a gunner and a commander located in one compartment and the mechanical components of the autoloader and breech of the gun located in the other compartment. When the gun is returned to the 0.degree. position for ejecting an empty case, the site of the director system remains on target. The turret is preferably mounted on a military land vehicle.

  • Patent number: 4848777
    Abstract: A casing seal for use with a source of high pressure fluids with apparatus for preventing shredding of the seal with variations in fluid pressure. A T-shaped annular metal ring provides a multiplication of fluid pressure so pressure exerted on an elastomeric sealing ring is greater than the fluid pressure. This multiplication prevents gases from entering the elastomer and prevents shredding of the elastomer when pressure is released. The multiplication of pressure also forces the elastomer firmly against a casing and a casing head to provide a fluid-tight seal.
