摘要:
A Reflux Rinsing method for purifying crystals using solvent vapor through dynamic equilibrium recrystallization. Feed material having tetrahydrocannabinol (THC) is inserted into a reaction vessel having walls, and upper portion, and a lower portion with a bottom surface. The feed material is exposed to a hydrocarbon liquid in the reaction vessel in a quantity sufficient to keep liquid present in equilibrium with gas in the reaction vessel through the recrystallization process, forming a raw extract having THC. The walls and bottom surface of the reaction vessel are coated with raw extract. The reaction vessel is heated and then the heating is discontinued. Vapor/thin-film DER is promoted in the reaction vessel for a predetermined length of time with no solvent reflux, resulting in formation of purified crystals of THC acid under pressure. The hydrocarbon solvent is reclaimed from the reaction vessel, leaving the purified crystals and impurities. When the reaction vessel is opened, the purified crystals and impurities are removed.
摘要:
A Reflux Rinsing apparatus for purifying crystals using solvent vapor through dynamic equilibrium recrystallization. A pressure vessel contains a liquefied gas solvent, impure crystalline starting material initially, and a purified crystalline mass at the conclusion of the purifying process. A mechanism is provided for providing pressure to contents of the pressure vessel and for heating the lower portion thereof. A timer is also connected to the mechanism, the timer being set to heat the pressure vessel to drive vapors and reflux rinsing to remove impurities at the surface of an impure crystalline mass, to reclaim the solvent, leaving purified crystals and impurities in the pressure vessel, and to open the pressure vessel to remove the purified crystals from the vessel walls and bottom surface and to remove the impurities from the vessel. The angle of a crystal bed in the apparatus can be adjusted.

摘要:
A method for purifying crystals in a glass or metal container. A hydrocarbon is introduced into feed material containing tetrahydrocannabinol (THC). The feed material and hydrocarbon is placed in a glass or metal container. The hydrocarbon is then removed within a few minutes after introduction, leaving at least some hydrocarbon in the feed material. Pressure is allowed to build within the container in an oven or in a jacketed vessel for 2-3 weeks. During this time, THC acid crystals precipitate out and fall to the bottom of the container. The contents of the container are poured into a Buchner funnel and a vacuum is applied thereto in order to pull terpenes into a beaker. The terpenes are placed into an oven in order to purge off any remaining solvent. The funnel is then scraped to acquire THC acid crystals.

A focused acoustic transducer suitable for use in a downhole environment is disclosed. At least some embodiments employ a disk of piezoelectric material with low planar coupling and low Poisson's ratio mounted on a backing material and sealed inside an enclosure. The piezoelectric material disk has a pattern of electrodes deposited on an otherwise smooth, ungrooved surface. Despite the lack of grooves, the material's low planar coupling and low Poisson's ratio enables the electrodes to operate in a phased relationship to provide and receive focused acoustic pulses. Moreover, the elimination of deep cuts offers a much lower cost of construction. The electrode material may be any conductive material, though silver and silver alloys are contemplated. The patterning of electrodes can occur during the deposition process (e.g., using a silk-screen or other printing technique) or afterwards (e.g., mechanically or chemically with an etch technique that uses a pre- or post-deposition photoresist layer).

摘要:
A device includes a piezoelectric transducer. The transducer has N independent transducer regions. N is an integer. Each of the N independent transducer regions has a thickness. Each of the N independent transducer regions has an acoustic impedance AIT. Each of the N independent transducer regions is independently excitable to oscillate in the thickness mode when electrically excited by a potential difference applied across the thickness. The device further includes a first impedance matching layer having an acoustic impedance AI1 and AIT and a borehole fluid acoustic impedance AIBF. The first impedance matching layer is situated such that an acoustic signal emitted by the piezoelectric transducer will pass through the second impedance matching layer. The device further includes a second impedance matching layer having an acoustic impedance AI2 between AI1 and AIBF. The second impedance matching layer is situated in the device such that an acoustic signal emitted by the transducer will pass through the second impedance matching layer after it passes through the first impedance matching layer.

In one of many possible embodiments, a hybrid end-user communication apparatus includes a Public Switched Telephone Network (“PSTN”) interface enabling communication over a Public Switched Telephone Network (“PSTN”) and a packet-switched network interface enabling signaling over a packet-switched network. The apparatus is configured to use the signaling to control a communication over the PSTN. In certain embodiments, the signaling includes Session Initiation Protocol (“SIP”) signaling. In certain embodiments, the communication over the PSTN includes a Public Switched Telephone Network (“PSTN”) media stream transmission over a Public Switched Telephone Network (“PSTN”) media bearer path.
摘要:
A product location display system and method are provided that allow travel related product information, such as the geographic location of hotels, to be displayed on an interactive display. An application server of the product location display system receives user inputted criteria for a travel product search. A location management system determines a location for the travel product being searched based on the inputted criteria. Sub-locations associated with the geographic location being searched are pre-defined as being within the searched geographic location and stored within a location database memory component coupled with the location management system. A display configuration component of the location management system arranges and displays results of the search for the travel product by the sub-locations defined as being within the searched location.
