  • Patent number: 4295337
    Abstract: Compressors are utilized in an apparatus for treating a product such as tobacco with a liquid cryogen, such as carbon dioxide for removing vapor from a processing chamber and recompressing the vapor to facilitate its return to the cryogen system. When the compressors do not receive a supply of cool vapor from the processing chamber, the compressor temperature rises and the pressure drops. When the pressure reaches a predetermined minimum setpoint, the compressors are interconnected by means of a remotely controlled valve to a vessel containing cryogen vapor at a pressure greater than the pressure at the compressors. A supply of cool cryogen vapor thus flows to the compressors to reduce the temperature, thereby allowing continuous operation of the compressors during periods in which cryogen vapor flow from the processing chamber is interrupted or delayed.

  • Patent number: 4275476
    Abstract: A molded ice scraper one piece body has independently flexible finger portions terminating in aligned scraping edges that are joined by webs a few thousandths of an inch thick. A continuous, but breakable, blade is thereby formed that will clean a streak-free swath on a windshield or similar surface. The slots separating the fingers are curved where they meet the scraper intermediate section, to eliminate stress concentration. The fingers have forward facing ice deflecting surfaces at an obtuse angle to the surface to be cleaned, extending from the scraper edge, and front facing ice chipping surfaces extending vertically upwardly from an intersection with the ice deflecting surfaces that is spaced back from the scraper edge.

  • Patent number: 4269560
    Abstract: A straddle carrier for heavy loads of the type which is driven over a load so that the load is generally beneath the carrier and straddled by the wheels of the carrier. The carrier includes a main frame which has a gripping tong mechanism integrally mounted thereon for clamping the load. The entire main frame and tong assembly may be raised and lowered to permit handling the load by means of cylinder/strut arrangements at each of the four wheels. A linkage comprising extensions from the wheel carrying members and a steering cross bar associated with each of the front and rear pairs of wheels is hydraulically activated independently of the main frame to permit steering the vehicle from any elevation. Mounted on the main frame, and like the main frame lowered and raised relative to the wheels, are an operator's cab and a motor and pump housing for driving the straddle carrier and actuating the various hydraulic cylinders of the carrier.

  • Patent number: 4223124
    Abstract: A method for decreasing the amount of ether as a by-product in polyesters (for example terephthalic-based) by initially utilizing a deficient amount of a glycol (for example, ethylene glycol) in the early reaction stages and utilizing an excess of the glycol in the final or end stages. The polyesters produced are of better quality, have a high melting point, possess increased thermal stability, and yield improved fiber properties.

  • Patent number: 4213726
    Abstract: A transport vehicle particularly useful for industrial uses and adapted to pick up, carry and subsequently dump a load-carrying receptacle comprising a U-shaped wheel-carried outer frame towed by a tractor which supports an inner U-shaped frame for picking up the receptacle. Vertical rear hoist cylinders elevate the inner U-shaped frame and rotate it about retracted dump cylinders to raise the inner U-shaped frame from an initial horizontal ground-level position to a forwardly tilted travel position. The dump cylinders can then tilt the inner frame about a pivot axis at its rear end to empty cargo from the receptacle. Latching and restraining mechanisms are provided to prevent the receptacle from tipping backward and sliding rearwardly with respect to the inner frame when dumping its load. The latching and restraining mechanisms are gravity-controlled and become inoperative when the inner frame resumes its forwardly tilted travel position.

  • Patent number: 4176007
    Abstract: A method and apparatus for removing porphyrins from a fluid sample which are unrelated to the number of bacteria present in the sample and prior to combining the sample with luminol reagent to produce a light reaction. The method involves a pre-incubation of the sample with a dilute concentration of hydrogen peroxide which inactivates the interfering soluble porphyrins. Further, by delaying taking a light measurement for a predetermined time period after combining the hydrogen peroxide-treated water sample with a luminol reagent, the luminescence produced by the reaction of the luminol reagent with ions present in the solution, being short lived, will have died out so that only porphyrins within the bacteria which have been released by rupturing the cells with the sodium hydroxide in the luminol reagent, will be measured. The measurement thus obtained can then be related to the concentration of live and dead bacteria in the fluid sample.

  • Patent number: 4164801
    Abstract: An ice scraper comprising a one-piece body defining a handle section, a downwardly curved intermediate section, and a blade region comprising a plurality of downwardly curved, independently flexible, resilient scraping fingers. In use, the scraping fingers bow or flex when scraping force is applied to ice to be removed, induce the formation of fractures in the ice, and thereafter resiliently return to their unflexed position, imparting force to fractured ice tending to throw it away from the surface to be scraped.The separable, independently flexible fingers enable the ice scraper to effectively conform to curved surfaces and avoid the possible incomplete cleaning action of said blade structures.
