  • Patent number: 8002047
    Abstract: A method for attenuating deflagration pressure produced by combustion of combustible gas in a defined region of a process vessel. The method generally comprises selecting and placing attenuating material in the defined region of the process vessel, wherein the selected attenuating material maintains its physical shape under the operating conditions. The attenuating material should occupy at least 20% of the volume of the defined region of the process vessel. Use of the inventive method may be beneficially applied for the safe operation of oxidation reactors with flammable, high hydrocarbon concentration feeds in order to attain increased productivity.
    Type: Grant

  • Patent number: 7435905
    Abstract: The electrical conduit body has a base section and an end section that forms an oblong box when joined together, and a cover removably attached to the box. The base section and the end section each have a semicircular recess forming a first port through the back wall opposite the cover. The base section has a second port extending through its closed end opposite the end section. In use, conduit wires are pulled through the second port and bent at a 90° angle towards the semicircular recess of the base section. The base section includes a pair of tongues for aligning and inserting into the grooves of the end section. The first port encircles the conduit wires as the base section and end section are brought together. The cover is secured to the box enclosing the wires within and fixing the end section and base section together.

  • Patent number: 4338885
    Abstract: Disclosed herein is a device for holding the head of cattle, livestock, and the like while the head of the animal extends through plural vertical rails which are laterally translatable, such rails commonly being used today to serve as a barrier one side of which the animals can find, of which is the feeding area of the livestock. The rails are caused to constrict the animal's head preventing withdrawal of the head by being more closely spaced, and thereafter the device according to the present invention is applied by hooking two ends of a pivot member between two successive rails and applying a snout engaging device on the animal, the device including a lever for forcing the animal's head in a constrained and still position against the rails and the device so that successive operations such as dehorning, medicating or the like can be administered to the animal while the animal's head remains stationary.
