摘要:
A composition of and a method of making high performance crosslinked membranes are described. The membranes have a high resistance to plasticization by use of crosslinking. The preferred polymer material for the membrane is a polyimide polymer comprising covalently bonded ester crosslinks. The resultant membrane exhibits a high permeability of CO2 in combination with a high CO2/CH4 selectivity. Another embodiment provides a method of making the membrane from a monesterified polymer followed by final crosslinking after the membrane is formed.

A toy projectile launching device for launching toy projectiles includes a spring shaped as a hollow hemisphere that is capable of being at least partially inverted from a primary normally convex position to a secondary at least partially inverted loaded position. Upon release, the spring snaps back to the primary position, thereby launching the toy projectile.

A system to produce a total product and recover inorganic salts from a combustion gas is described. The system includes a contacting zone, a regeneration zone and a recovery zone. The contacting zone is configured to fluidize a supported inorganic salt catalyst in the presence of a feed, steam, and a hydrogen source to produce the total product. The regeneration zone is configured to receive at least a portion of the supported inorganic salt catalyst from the contacting zone and remove at least a portion of contaminants from the supported inorganic salt catalyst. The recovery zone is configured to receive combustion gas from the regeneration zone, wherein the recovery zone is configured to separate at least a portion of inorganic salts from the combustion gas.
摘要:
A system and method for remote monitoring of material storage levels for dry bulk goods, wherein an independent entity, such as a transportation carrier, can continuously monitor raw material supply levels at a remote manufacturing plant, and, based on projected usage rates, place timely orders on behalf of the plant, with preselected vendors, to replenish depleted raw materials. The transportation carrier can then coordinate material shipments from the vendor to the manufacturing site using its own trucks. In this manner, the task of maintaining sufficient on site raw material storage levels is completely removed form the manufacturing plant.

Server accessible case records are generated for post-diagnostic and remote access viewing. First, a master sequence of digital video images is recorded. Next, a post-diagnostic case record is generated including a sequence of thumbnail images and a single lossless still image selected from the master sequence of images. The images of the post-diagnostic case record are formatted to be accessible by a browser over a dial-up connection. Each image of the sequence of thumbnail images includes a selection of interior pixels of one of the digital video images of the master sequence. The sequence of thumbnail images is a selection of consecutive images from the master sequence. The post-diagnostic case record and the master sequence are then stored on an image server. The master sequence is archived onto a secondary archive medium after a predetermined time.
摘要:
A sterilization system includes a controller, a transformer including a primary side in communication with the controller and secondary side, an ozone generator in communication with the secondary side of the transformer and the controller, and a power source in communication with the controller, wherein the ozone generator ionizes atmospheric oxygen through the application of corona discharge.
摘要:
This disclosure relates to agricultural canopies used primarily to control the amount of light and/or moisture and/or heat reaching growing plants within the canopy footprint. More specifically, it relates to mechanisms for pulling a flexible canopy over a support structure and then for removing the canopy to uncover the structure and the plants below. The mechanisms include an arm mounted rotationally on a base. When the arm is rotated in one direction the canopy is pulled over the support structure and when the arm is rotated in the other direction the canopy is pulled off the support structure.
