Abstract: A fibrin glue applicator system is provided for dispensing a first and a second protein solution which form a biological adhesive when intermixed on an application site. The fibrin glue applicator system includes a coupler interface, a disposable loading unit (DLU), and a housing having a handle portion which includes a trigger operatively associated with a slide bar for dispensing the solutions from the DLU. Each piercer is in fluid communication with one of two cylinders of the DLU via a respective conduit connected to a respective main conduit. A first one-way valve is included within each conduit to open and close a path leading from the piercer to the main conduit. The first one-way valves are forced open by air pressure created when the loading lever connected to two pistons of the DLU is translated proximally causing the protein solutions to be transferred to their corresponding cylinder. The DLU is then mounted to the housing. The solutions are dispensed via two dispensing orifices each in fluid communication with one of the main conduits. A second one-way valve is fixed within each main conduit in proximity to each dispensing orifice to open and close a path leading from each cylinder to its corresponding dispensing orifice. The second one-way valves open when the solutions are forcibly transferred from the cylinders to the main conduits by depressing the trigger for dispensing the solutions from the two dispensing orifices. The first and second protein solutions are preferably fibrinogen and thrombin solutions which intermix on the application site to form a fibrin sealant.

Title: Tapered electrode for plasma arc cutting torches
Inventor: KABIR A A S AREFIN
IPC: H05H1/38
Filed: 2000-03-30
Granted: 2004-06-01
Abstract: An electrode for a plasma arc cutting torch, wherein the electrode comprises a holder having a tapered tip and emissive element concentrically disposed therein. The holder has an included angle of taper at the tip of between about 25°  and about 40° and a diameter at the tip approximately equal to, or slightly larger than, the diameter of the end surface of the emissive element. The electrode is configured such that the holder comprises a relatively thin holder wall at the tip of the electrode which evaporates due to the heat from the adjacent arc generated through the emissive element such that the tapered tip erodes generally simultaneously with the emissive element. Generally simultaneous erosion of both the holder and the emissive element thus avoids the problems of overheating and/or double arcing and extends the service life of the electrode. A method of operation of a plasma arc torch is also provided.

Title: Reactions of aromatic compounds
Inventor: RAMSHAW COLIN
IPC: B01J19/00
Filed: 1998-11-05
Granted: 2007-09-18
Abstract: A method of reacting an aromatic compound with an immiscible reacting agent involves the passage of the reactant along a flow path having a width of from 10 to 1000 µm in such a way that essentially laminar flow of the reactant takes place. Reaction takes place across the interface between the phases and without substantial mixing of the unreacted aromatic compound and the reacting agents. A  preferred reaction is the nitration reaction which involves reaction of a first phase comprising an organic aromatic compound on a second phase comprising a nitrating agent to produce two new phases of different chemical composition to the starting phases. The aqueous and organic phases produced are ideally separated such that minimum contamination occurs. Other examples of this type of reaction include the sulphonation of an aromatic compound using sulphuric acid as the sulphonating agent. The aromatic compound is slowly consumed in the reaction yielding a single aqueous phase.

IPC: H04L12/28
Filed: 1999-09-29
Granted: 2009-01-06
Abstract: A method of operating a radio communication system uses orthogonal signals f or transmission of packets of data between two or more stations. In the transmitter data is encoded (204, 206, 208) onto a plurality of orthogonal carriers by a differential phase modulation technique, for example DQPSK. The carriers are combined into a single signal by an inverse discrete Fourier transform (210) and clipped at a predetermined amplitude (212) before being transmitted (218) to reduce the crest factor of the transmitted signal. The phase of one or more of the carriers is randomised before each data packet, hence a different crest factor will result for retransmissions of the same packet. This ensures that if a packet is difficult to transmit, because of reduced signal to noise ratio caused by clipping, it will retransmit successfully.

Granted: 2006-03-07
Abstract: Input buffer type packet switching equipment, which can output cells to an external output line having a slower output line rate than a corresponding input line rate without having buffers in its output line sections, is provided. The input buffer type packet switching equipment provides M input line buffers that store cells inputted from M input lines temporarily in a state that one of the M input line buffers stores cells inputted from corresponding one of the M input lines, in this the M is an integer being 2 or more, an M × N crossbar type switch, which provides N output lines, for switching cells outputted from the M input line buffers based on a cross point on/off control signal, in this N is an integer being 2 or more. The input buffer type packet switching equipment further provides N output line sections, which are provided for each of the N output lines of the M × N crossbar type switch, for outputting cells applied switching at the M × N crossbar type switch to N external output lines, and an arbiter that outputs a connection permission signal to one of the M input line buffers based on connection request signals outputted from the M input line buffers, and also outputs the cross point on/off control signal to the M × N crossbar type switch, and outputs the connection permission signal at a designated slower timing interval than a normal timing interval to one input line buffer that outputs cells to an external output line whose output line rate is slower than a corresponding input line rate. With this, the timing interval outputting the cells from one of the M input line buffers to the M × N crossbar type switch is made to be wider than the normal timing interval, therefore buffers in the output line sections are not needed.
