IPC: E05B15/02
Filed: 2000-06-07
Granted: 2012-01-17
Abstract: A remote control door entry system, which may be installed in a door jamb/frame, in the center frame post of a door assembly that has a side light glass unit, or centered in the edge of the stationary door of a double door arrangement. The entry system is used for controlling a lock having a spring latch bolt (274) and a dead latch bolt (276). A slide bolt (44) engages and compresses the dead latch bolt (276) in a locked position (Fig. 3a). In an intermediate position the dead latch bolt (276) is released by the slide bolt (44), and in a further unlocked position another slide bolt (4) engages and compresses both the spring latch bolt (274) and the dead latch bolt (276).

Title: Recombinant parainfluenza virus vaccines attenuated by deletion or ablation of a non-essential gene
Inventor: DURBIN ANNA P
IPC: C07K14/115
Filed: 2000-07-06
Granted: 2012-03-27
Abstract: Recombinant parainfluenza virus (PIV) are provided in which expression of the C, D and/or V translational open reading frame(s) (ORFs) is reduced or ablated to yield novel PIV vaccine candidates. Expression of the C, D and/or V ORF(s) is reduced or ablated by modifying a recombinant PIV genome or antigenome, for example by introduction of a stop codon, by a mutation in an RNA editing site, by a mutation that alters the amino acid specified by an initiation codon, or by a frame shift mutation in the targeted ORF(s). Alternatively, the C, D  and/or V ORF(s) is deleted in whole or in part to render the protein(s) encoded thereby partially or entirely non-functional or to disrupt protein expression altogether. C, D and/or V ORF(s) deletion and knock out mutants possess highly desirable phenotypic characteristics for vaccine development.  These deletion and knock out mutations changes specify one or more desired phenotypic changes in the resulting virus or subviral particle. Vaccine candidates are generated that show a change in viral growth characteristics, attenuation, plaque size, and/or a change in cytopathogenicity, among other novel phenotypes. A variety of additional mutations and nucleotide modifications are provided within the C, D and/or V ORF(s) deletion or ablation mutant PIV of the invention to yield desired phenotypic and structural effects.

Granted: 2008-12-16
Abstract: L'invention concerne un applicateur de produit cosmétique présentant un réseau de disques indépendants qui se compressent lorsqu'ils sont extraits d'un contenant, de telles sorte que l'excès de produit puisse être retiré de l'applicateur au moyen d'un élément d'essorage. Après le passage des disques à travers l'élément d'essorage, les disques retrouvent leur position étalée grâce à l'action d'un ressort. La compression des disques pendant leur extraction permet de commander la quantité de produit devant rester sur l'applicateur et, donc, la quantité nécessaire à l'utilisateur. Le retour des disques dans leur position étalée grâce au ressort permet aux disques de conserver une configuration permettant à l'applicateur de brosser et de séparer efficacement les cils.

Inventor: PALMER GARY
IPC: C10L3/10
Filed: 2004-03-25
Granted: 2011-04-19
Abstract: The arrangements described herein are based upon a theory of selective absorption of hydrogen sulphide over carbon dioxide from gas based on countercurrent contact between gas and tertiary or other amines which exhibit preferential affinity for H2S over CO2 primarily because of differential rates of absorption of the two gases. The process of enhanced selective absorption is accomplished by performing the absorption in two steps. The first operation is to contact lean amine with sour gas which contains both H2S and CO2. The object of the first operation is to produce an overhead gas that meets an arbitrary standard for content of H2S and CO2. The second operation is to enhance the selectivity for H2S by contacting the rich amine leaving the first operation with a second gas which is a highly concentrated acid gas having a higher H2S/CO2 ratio than the first acid gas.
