Title: A fire extinguishing device
Inventor: NIELSEN PER FINN
IPC: A62C31/12
Filed: 1998-12-18
Abstract: The invention relates to a fire extinguishing device (1) of the kind which comprises at least one liquid conduit connected at one end to a source with a fire extinguishing liquid under pressure, and at the other end with channels (40, 23) in a nozzle head (21) with a number of nozzles (24, 27). The channels of the nozzle head comprise a first channel (40) connected to at least one atomising nozzle (27) for discharging liquid in atomised form, and a second channel (23) which has an air intake (25) and downstrean of this is connected to a foam nozzle (24) for discharging a liquid in foamed form. The device can be utilised for effectively extinguishing class A, B, C, and E fires and can, with one single handle, be converted to fighting fires with either foam or water. The water can be atomised to a very high fineness by means of a relatively slight pressure of about 10 - 25 bar, and a range of over 10 metres is obtained. Far less water is used for extinguishing a fire than when using conventional fire extinguishing equipment.

Abstract: An improved method and system for providing packet-switched management of switching and handoff functions for a mobile terminal during call setup and user communication phases of a telecommunication session. A radio access network (RAN) including an air-interface base station in communication with the mobile terminal is in communicative contact with a packet-switched core network comprised of a plurality nodes which provide functionality that is equivalent to that of a network of Mobile Switching Centers (MSCs) and Visitor Location Registers (VLRs). A packet-switching backbone network provides communication transport facilities within the core network. Within the core network is a wireless access gateway (WAG) having media channels that provide an interface between the RAN and the core network. An Anchor Packet Gateway (APG) extends the bearer path from the WAG, and hides mobility between WAGS during the user communication phase. A wireless mobility server (WMS) in communicative contact with the WAG and APG serves as a media gateway controller for the WAG and APG, controlling connectivity of the media channels within the WAG and APG. A PSTN Trunking Media Gateway (PTMG) provides connectivity between the core network and the PSTN. A Call Server (CS) in communicative contact with the PTMG and WMS serves as a media gateway controller for the PTMG and WMS, where the WMS presents the appearance of a media gateway to the CS, but in fact functions as a media gateway controller for the WAG and APG. The CS and WMS together present the appearance of a single MSC/VLR to the public cellular or PCS network.

Inventor: DICKHAUT JOHN
IPC: B25C7/00
Filed: 2001-03-02
Abstract: An accessory device for fastener-driving tools such as nail and staple guns is provided. The device serves as a positioning guide for the tool and is designed to provide sufficient spacing and orientation between the fastener-driving tool and the target construction material. The device can be integrated into the beady of the fastener-driving tool, manufactured as an attachment or manufactured as a separate tool. It prevents impact marring at the visible surface of the construction material by redirecting the force of the blow to a non-visible surface on the assembled construction material. Furthermore it increases speed and ease of movement for the user by serving as a guide for stability and ease of alignment. The device changes the impact point between the driving tool and the construction material, broadens the area of impact and protects the top edge of a tongue and groove construction material from impact damage.

Title: Methods and compositions for use in spliceosome mediated rna trans-splicing
Inventor: MITCHELL LLOYD G
IPC: A61K38/00
Filed: 1999-08-12
Abstract: The molecules and methods of the present invention provide a means for in vivo production of a trans-spliced molecule in a selected subset of cells. The pre-trans-splicing molecules of the invention are substrates for a trans-splicing reaction between the pre-trans-splicing molecules and a pre-mRNA which is uniquely expressed in the specific target cells. The in vivo trans-splicing reaction provides a novel mRNA which is functional as mRNA or encodes a protein to be expressed in the target cells. The expression product of the mRNA is a protein of therapeutic value to the cell or host organism a toxin which causes killing of the specific cells or a novel protein not normally present in such cells. The invention further provides PTMs that have been genetically engineered for the identification of exon/intron boundaries of pre-mRNA molecules using an exon tagging method. The PTMs of the invention can also be designed to result in the production of chimeric RNA encoding for peptide affinity purification tags which can be used to purify and identify proteins expressed in a specific cell type.
