  • Patent number: 10219529
    Abstract: A method for manufacturing an edible dog chew includes the steps of: extruding a first edible mixture through a mold having an opening in a first direction to form a lengthened chew interior material; cutting the lengthened chew interior material into defined lengths to form at least one cut chew interior material; drying the cut chew interior material to form a chew interior; and coating the chew interior with a second edible mixture different from the first edible mixture. Further methods and pet chews are also provided.

  • Publication number: 20170251697
    Abstract: Dog chews with an inner material and an outer coating. The animal-hide materials of the present invention, when used as an inner material, advantageously can increase durability and chew times. A meat-based coating, when used as the outer coating, advantageously can increase taste of the interior material.

  • Patent number: 8975880
    Abstract: A switching regulator arrangement utilizes internal capacitors rather than external capacitors for driving output power transistors. Low-dropout linear voltage regulators together with a dip compensation circuit provide an intermediate supply voltage for driving power transistors under circumstances in which a supply voltage is greater than a gate drive voltage of the power transistor, allowing for a more efficient absorption of transient current.

  • Publication number: 20090078610
    Abstract: This invention, which involves a method of turning vegetable asphalt into high-quality boiler fuel, belongs to the field of natural asphalt processing technology. It is intended for acid desaponification of vegetable asphalt at 50 to 100° C., then water washing is performed removing impurities and salt; following this, the asphalt is allowed to stand to separate into layers and the aqueous phase is removed. Neutralization to pH=7 to 8 is then performed using alkali and, after another water wash is performed, the asphalt is allowed to stand to separate into layers and the aqueous phase is separated from it. Then the substance obtained thereby is dried yielding the product. Vegetable asphalt that has undergone modification has the advantages of having low viscosity, generating a small amount of ash, having low sulfur content and a low flash point, and of not being prone to coking when it is burned, and the like, and ensures boiler heat efficiency and also prolongs boiler's useful life and reduces pollution.

  • Publication number: 20090069615
    Abstract: This invention discloses a method and equipment for preparing isobutylene using tertiary butyl alcohol. The equipment comprises a reaction vessel and a separating column. The upper portion of the separating column is fitted with a column top condenser, and the bottom of the column is fitted with a heater. The reaction vessel and the separating column are connected to each other by means of a pipe. One end of the dehydration column is connected to the heater at the bottom of the separating column, and the other end, after passing through a cooling unit, is connected to a distributor at the top of the separating column. A condenser with an outlet is connected to the outside of the said column top condenser.

  • Patent number: 4187450
    Abstract: A transformer particularly useful in conjunction with solid state high frequency push-pull inverter supplies for discharge lamps is disclosed. In accordance with one embodiment of the present invention, two E-shaped core sections are disposed adjacent to one another in a mirror image fashion with corresponding core legs aligned but with an air gap provided between the middle legs of the core structure. The transformer disclosed permits the use of non-bifilar winding methods in the manufacture of transformers particularly useful in square-wave push-pull inverters used in discharge lamp ballasting circuits. In addition, the core structure disclosed provides for an integral ballasting reactance which minimizes power loss induced in the surrounding metal casing or other nearby metal structures.
