Abstract: A portable controlled environment is formed from a suspended roof tarpaulin that snares an interior perimeter frame from which wall tarpaulins depend. The frame is preferably of lightweight tubing and forms a closed figure. The roof tarpaulin is preferably conical or pyramidal and had a suspension lug at its apex for attachment to a block and tackle or a boom. The perimeter of the roof tarpaulin retains a snaring cable that when drawn tight snares the frame against the suspended roof. Adjacent wall tarpaulins depending from the perimeter frame are joined by zippers to from an enclosure.     The enclosure may be advantageously used to grow plants. The walls and roof can be made from either reflectant or selectively transmitting material to either decrease or increase the interior temperature with respect to the surrounding environs. The enclosure can include roof and wall vents to encourage drafts to aerate the enclosure and maintain a desired temperature and humidity. Forced air flow can be used to accomplish the same end. For hydroponics use, a watering manifold provides nutrients and water to the plant roots while protecting the sensitive roots from damaging light and the sensitive leaves from damaging nutrient fumes.

Title: Method and apparatus for pollution control
Inventor: PATTERSON RONALD G
IPC: B01D47/06
Filed: 1994-01-03
Abstract: A pollution control system (10) and  method  in  which hot flue gas is cooled to saturation in a quencher (8) and passed through a  condenser absorber assembly (13) to further cool the saturated gases while growing small particles as the particles act as nuclei for the condensation  of water vapor thereon. The grown particles are carried through an aperture (52, 53, 54) having a low pressure drop throat so that high  efficiency particle collection is accomplished.  At its outlet, the aperture produces a concentration of the gases and water droplets.  A dome shaped gas reverser (62, 63, 64) having its concave surface  directed  upstream, is located spaced apart from the aperture (52, 53, 54) in substantial aligment with the outlet of the aperture (52, 53, 54).  The gas reverser (62, 63, 64) receives the gas stream as it exits the aperture (52, 53, 54), mixing and diffusing the gas and its constituents as they change direction to spill out over the lip of the gas reverser (62, 63, 64).  An electrostatic precipitator (23) is disposed downstream of the gas  reverser (62, 63, 64) to remove  the remaining particulate and fine water droplets from the gas stream.

Title: Method and apparatus for encoding and formatting data representing a video program to provide multiple overlapping presentations of the video program
Inventor: TOM ADAM S
IPC: H04N7/173
Filed: 1995-10-19
Abstract: Virtually random and on-demand access is provided to a virtually unlimited number of subscribers by partitioning the video program into an ordered sequence of n segments and providing the subscribers concurrent access to each of the n subsequences. A data stream representative of the video program is positioned into n subsequences, each representative of one of the n segments. The data of each of the n subsequences is organized as ordered sequence of elements. The elements of each of the n subsequences are interleaved and the interleaved data stream is continuously transmitted over a video program distribution medium at a rate which renders the date representing each segment concurrently available to any subscriber having a receiver capable of selecting, assembling, and displaying the data of a particular segment. The date stream can be compressed prior to interleaving using one of many known video data compression standards and techniques. Data compression can be performed in real time, or iteratively using software. The interleaved data stream can be transmitted in real time, or it can be stored on a storage device such as a hard disk or optical disk for later retrieval and transmission. The interleaved data stream can be ordered using any known standard by which video data is transmitted for reconstruction and display by a receiver. Data can be inserted into the interleaved data stream to inform the receiver to which of the n segments a portion of the interleaved data stream belongs, as well as the encoding level necessary for decompression of the data and time stamps to indicate order of display. Thus, the receiver may begin reconstruction from the beginning of the video program by selecting, assembling, decompressing and displaying the data making up the first segment during a first complete transmission of the interleaved data stream, and performing the same function for the succeeding segments during subsequent transmissions. The receiver can also be programmed to reconstruct any of the n segments in no particular order, approximately random access to the video program.

Title: Cam-operated timer pawl drive
Inventor: AMONETT DANIEL KEITH
IPC: H01H43/10
Filed: 1997-05-28
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which means a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.
