Title: Pansements pour dispositifs medicaux transcutanes et procede d'utilisation
Inventor: BURRELL ROBERT EDWARD
IPC: A61M25/02
Filed: 2001-03-09
Abstract: L'invention concerne un pansement pour un dispositif transcutané et son procédé d'utilisation avec un dispositif médical transcutané, tel qu'un cathéter intravasculaire, poncturant la peau d'un patient et présentant une portion sortant de la peau susceptible d'entraîner une infection.  Ce pansement comprend un pansement supérieur et un pansement inférieur, tous deux formés à partir d'un matériau souple et présentant une surface supérieure et une surface inférieure, la surface inférieure étant la surface de contact avec la peau. Une fente est ménagée sur le pansement inférieur, elle s'étend vers l'intérieur depuis un angle jusqu'à un point de terminaison se trouvant à l'intérieur des confinements du pansement inférieur. Une matière antimicrobienne est disposée, sans adhésifs, sur les surfaces supérieures et inférieures du pansement inférieur, et au moins sur la surface inférieure du pansement supérieur. Dans la pratique, le pansement inférieur est placé à côté de la peau, la fente permettant au pansement inférieur d'entourer le site de ponction, de telle sorte que la surface du pansement inférieur soit en contact avec une portion du dispositif médical sortant de la peau. Le pansement supérieur est placé par-dessus le site de ponction, de telle sorte que sa surface inférieure soit en contact avec une portion du dispositif médical sortant de la peau. De cette façon, la portion du dispositif médical sortant de la peau est exposée à l'activité antimicrobienne du matériau antimicrobien.

Title: Mobile shelter comprising an umbrella-like collapsible marquee
Inventor: BOUCHARD PAUL-ANDRE
IPC: E04H15/06
Filed: 2003-09-26
Abstract: A mobile shelter comprising a vehicle, a post pivotally attached to the vehicle at one end, and releasably attached at the other end to an umbrella-like collapsible marquee. The marquee comprises a frame, whereby the marquee is attached to the post, a number of articulated brace assemblies pivotally connected to the frame, each brace assembly comprising a number of pivotally interconnected braces. The brace assemblies define a ground-resting end, and a pivot joint pivotally attached to a spreader ring, which in turn slidably engages the post. Upon sliding the spreader ring up and down about the post, the brace assemblies can be shifted between: - a storage position, in which the brace assemblies are collapsed against the post and the ground-resting ends of the brace assemblies are located at the vicinity of the post; and - a deployed position, in which the brace assemblies are deployed away from the post, the ground-resting ends of the brace assemblies are spaced-apart from the post and rest on the ground, and in which the spreader ring is releasably attached to the frame. To install the marquee, the post is pivoted away from the vehicle into a vertical stance, and the spreader ring is slid upwardly about the post, in order to shift the brace assemblies from their storage position to their deployed position, similarly to an umbrella. Then, once the brace assemblies are in their deployed position, the post can be released from the marquee's frame, and the vehicle can be driven away from the marquee with the post.

Title: Compensation circuit for sensor lag to reduce undershoot and overshoot
Inventor: BECKEY THOMAS J
IPC: G05D23/19
Filed: 1989-10-17
Abstract: A compensation circuit 2 for sensor lag provides a modified sensor temperature signal for subsequent use in controlling the sensed temperature. The compensation circuit 2 digitally compares a current sensor temperature representative signal and a sensor temperature signal at a last or preceeding sample time to produce a difference signal which is converted to a sensor slope signal 16 and is multiplied by a sensor time constant 18. The resulting signal is passed through a filter 20 to eliminate transient effects and is summed with the original sensor temperature signal to provide a sensed temperature signal for control of the temperature whereby the sensed temperature is a better estimate of the actual environmental temperature controlled by a thermostat utilizing the sensed temperature signal.

Title: System for detecting transition and rare earth elements in a matrix
Inventor: KINGSTON HOWARD M JR
IPC: G01N30/88
Filed: 1990-03-01
Abstract: ABSTRACT OF THE DISCLOSURE         In many environmental and biological samples there are present large amounts of alkali metal and alkaline earth metal, as compared to the amounts of transition elements and rare earth elements.  With these samples conventional ion exchange concentration methods are not selective enough for determination of trace and ultra-trace amounts of transition elements and rare earth elements.  The invention provides a method and apparatus for detecting selected trace transition elements or rare earth elements in samples containing alkali metals or alkaline earth metals.  The sample is passed through chelator means under conditions which retain all the trace element but only part of the alkali.  Remaining alkali is stripped by means of a first eluant while trace elements are retained.  Thereafter the trace elements are stripped with a second eluant, concentrated, stripped from the concentator by means of a third eluant and passed to a detector.

Abstract: ABSTRACT OF DISCLOSURE      Method and gas burner assembly for producing amongst the arrangement of non-combustible logs, and essentially yellow flame  pattern  with  substantially  low  levels  of  carbon monoxide production.  In general, method hereof employs a gas burner assembly having one or more burner each having a plurality of gas jets.   The burner assembly  is disposed between the combustion chamber of fireplace enclosure which contains a predetermined volume of combustion chamber air which is continuously provided from outside of the combustion chamber.   Non-combustible fireplace logs are arranged above the gas burner assembly so as to provide one or more flow pathss between the burner and adjacent logs,  for allowing free flow of combustion chamber air through the flow paths and about the burners.  Flow of gas is provided through the burners so that the gas flows out of the gas jets and mixes with the combustion chamber air about the jets of the burner.          Combustion chamber air flowing through the flow paths and about the burner is concentrated so that the flame pattern has  essentially  a  yellow color,  and  the  logs  above  the burners are maintained at a sufficient temperature so that combustion gases flowing out of the fireplace exhaust have substantially  low  levels  of  carbon  monoxide.    In  the preferred  embodiment,  an  H-shaped  burner  is  used  in practicing the method of the present invention.

Filed: 1990-05-23
Abstract: ABSTRACT OF THE DISCLOSURE      A method and an arrangement for automatically aligning horizontal rolls and vertical rolls in a universal rolling mill stand after the stand has been changed to new types of sections in a rolling mill train.  The axial geometric configuration of the vertical rolls in the stand serve as a fixed reference value and the horizontal rolls are displaced radially and axially into roll positions which are measured by actual position indicators and from which the geometric roll gap center and the geometric roll center in the stand are determined.  For taking into consideration the spring characteristic constants of the stand, the radial spring characteristic for the two horizontal rolls is determined together, the radial spring characteristic for each vertical roll is determined separately and the axial spring characteristic of one of the horizontal rolls is determined separately in accordance with one of the two axial directions.  The rolls are moved towards each other electro-mechanically until a moment of contact and subsequently the roll body pressure is hydraulically increased to at least two pressure points and then the roll body pressure is relieved from the pressure points.
