Title: Bed having patient warming apparatus
Inventor: HOPPER CHRISTOPHER J
IPC: A47C21/04
Filed: 1993-01-04
Abstract: A hospital bed (10) has an articulated patient support surface (24) with four air outlet housings (26, 27, 28, 29) mounted thereon at spaced locations. An air supply arrangement (43) supplies temperature-controlled air to an air outlet opening in each of the housings (26, 27, 28, 29). Associated with each housing (26, 27, 28, 29), is an elongate tubular fabric diffusion member (42) having an O-ring (63) which encircles one end (62) thereof and is removably received in a circumferential groove (77) in the air outlet opening. Each diffusion member (42) can be tucked completely into its housing (26, 27, 28, 29) when not in use. Each housing (26, 27, 28, 29) has a cap (92) movable between open and closed positions with respect to the air outlet opening, and an arrangement yieldably urging the cap (92) toward its closed position. A valve arrangement (161) is provided below two of the housings (26, 27) in order to automatically discharge fluids which happen to enter the air supply system (43) through the air outlet openings. In a variation, two of the elongate diffusion members (42) can be replaced with an inflatable underlay (212) or overlay (220) having two inlet sleeves (218, 219) with O-rings (221) which are each releasably coupled to a respective one of the air devices.

Title: Electron amplifier and method of manufacture therefor
Inventor: HICKS JOHN W JR
IPC: H01J21/10
Filed: 1991-02-22
Abstract: A novel vacuum tube type of electric apparatus preferably utilizes cold cathode emission to provide an electron source. A grid element (24) is employed to vary path direction for the particles, which are directed to alternative positions of an anode element (16). Secondary electron emission from a portion of the anode (36) is utilized to permit the anode potential to rise upon electron impingement, while a second portion of the anode (34) retains electrons to drive the anode potential in the negative sense. The structure allows both positive and negative states to be maintained, and has value in both rapid switching and memory application.  The tube is advantageously manufactured on an insulating substrate which may be drawn to microscopic dimensions. This permits a dense pack to be accomplished, with low power requirements and high operating speed.

Filed: 1993-10-01
Abstract: Molecular cloning and expression of a prostaglandin F2.alpha. receptor which is linked to the signal transduction pathways via guanine nucleotide binding regulatory (G) proteins and measured by, for example, cAMP, IP3 or intracellular calcium. By constructing cell tines that express a prostaglandin F2.alpha. receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding a prostaglandin F2.alpha. receptor. A host cell is transformed with a recombinant DNA  construct, so that the DNA-fragment is expressed and a prostaglandin F2.alpha. receptor is produced. Suitable host system includes euk~tic and prokaryotic cells, especially mammalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies ~  prostaglandin F2.alpha. receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals. Using the resulting antibodies, expression of an F2.alpha. receptor cDNA, i.e. receptor protein in tissue and cells can be measured.

Title: Measurement/control of sheet material using at least one sensor array
Inventor: WILLIAMS PAUL
IPC: G01N9/24
Filed: 1995-04-03
Abstract: A paper web is monitored for measurement and manufacturing control by a stationary web sensor extending across the entire web which is raster scanned by the motion of the web. Massive amounts of data are processed by a look up table memory addressed by digitized sensor data and the output from a reference memory containing element specific information. The lookup table is loaded with data to define a characteristic or property of the web corresponding to digitized sensor data interpreted in view of element specific data from the reference memory. Rapidly processed data is stored in a memory in a form facilitating its display and interpretation by an operator of the web manufacturing machine and also control of the machine.      By controlling operation of the machine, uniformity of the web is substantially improved and, by taking the measurements closely adjacent the initial processing end of the web, corrections of nonuniformity in the web are quickly effected.      To measure and control absolute characteristics and properties of the web, a second, preferably stationary, sensor adjacent the finished end of the web monitors the web adjacent a takeup reel.      Alternately, for basis weight measurement and control, the weight of the takeup reel is monitored and combined with the web width and machine operating speed to determine an absolute web basis weight. Thus, uniformity of the web and absolute values of characteristics and properties of the web can be measured and controlled.
