Title: Restoration network architecture
Inventor: ESLAMBOLCHI HOSSEIN
IPC: H04B1/74
Filed: 1998-01-15
Abstract: A network (100) capable of quickly restoring traffic includes main and tertiary communications media (103, 105), each having associated main channels (102 1-102n) and tertiary channels (104 1-104m), respectively. A first main channel (102 1) and first tertiary channel (104 1) run in parallel between a pair of digital signal protection switches (106 1, 106 2) coupled to a pair of digital cross-connect systems (108 1, 116) that are spanned by the remaining main channels (102 2-102n) and tertiary channels (104 2-104m) in parallel. A controller 120 is responsive to the traffic on the main communications medium for signaling the first and second digital protection switches (106 1, 106 2) to switch traffic from the first main channel (102 1) to the first tertiary channel (104 1) should the first main channel become unavailable. The controller also subsequently signals the first and second digital cross-connect devices, which switch slower than the digital signal protection switches, to switch traffic from one or more of the other main channels to corresponding tertiary channels should such main channels become unavailable.

Inventor: OOI PEGGY
IPC: A61P31/04
Filed: 1997-07-23
Abstract: A protein from H. influenzae designated NucA is isolated and purified. The NucA protein has the amino acid sequence of amino acids 26-603 of SEQ ID NO.2 or a biologically equivalent amino acid sequence thereof. Amino acids 1-25 of SEQ ID NO.2 are the signal peptide, which is cleaved during processing of the mature protein. The NucA protein has a molecular weight of approximately 63,000 Daltons as measured on a 12 % SDS-PAGE gel and possesses 5'-nucleotidase activity. The NucA protein is obtained by isolation and purification from the H. influenzae organism, by chemical synthesis or by recombinant expression by an isolated and purified nucA DNA sequence which encodes the NucA protein. Such a DNA sequence hybridizes under standard high stringency Southern hybridization conditions with a DNA sequence encoding the NucA protein of H. influenzae having the amino acid sequence of amino acids 26-603 of SEQ ID NO.2 or a biologically equivalent amino acid sequence thereof.  The NucA protein is used to prepare a vaccine composition which elicits a protective immune response in a mammalian host to protect the host against disease caused by H. influenzae.

Title: Method of continuously dissolving rubber
Inventor: MAEDA TETSUO
IPC: C08F279/02
Filed: 1998-04-06
Abstract: A method of dissolving a rubber continuously to form a raw material for the production of rubber-modified polymer, by dissolving a rubber in a monomer liquid dissolving the rubber and capable of reacting with the rubber in the presence or absence of a solvent. Pieces of rubber are fed continuously to a dissolution tank to allow the dissolved rubber and the undissolved rubber to coexist in the dissolution tank, wherein the concentration of the dissolved rubber is the concentration at which the feeding to the reactor is made, and the quantity of the undissolved rubber present in the dissolution tank is at most the quantity that prevents pieces of the undissolved rubber from sticking to one another to form larger rubber masses. The time required for dissolution can be shortened, and the size of a dissolution tank can be made smaller, compared with the conventional methods.

Title: Filling of tanks
Inventor: CARTER RODNEY
IPC: B65D88/54
Filed: 1996-10-14
Abstract: Apparatus for the filling of a tank (10) with a volatile liquid includes a delivery pipe (15) having a pair of tubular distribution members (16 and 17) hinged to the lower end thereof. The distribution members may hinge between an insertion position where they lie parallel to the axis of the delivery pipe (15) and a deployed position where the members are co-axial but extending normally to the axis of the delivery pipe. When in their insertion position, the distribution members (16 and 17) as well as the delivery pipe (15) may be passed through the conventional fill-pipe (13) of the tank (10), the distribution members then hinging to their deployed position as the lower end of the delivery pipe approaches the bottom of the tank. The delivery pipe (15) is in communication with the interior of the distribution members (16 and 17) when the latter are in their deployed position. Holes (20) are formed along the length of each distribution member so that volatile liquid fed down the delivery pipe in the tank is distributed throughout the area of the tank, so minimising turbulence of liquid already in the tank.

Title: Compressor intercooler unloader arrangement
Inventor: CUNKELMAN BRIAN L
IPC: F04B25/00
Filed: 1998-06-30
Abstract: Apparatus for rapidly unloading air pressure in an intercooler to atmosphere when a compressor pneumatically connected to the intercooler is unloaded. The apparatus includes a governor pneumatically connected to a reservoir, that, in turn, is connected to receive pressurized air from the air compressor. The governor has a pressure sensing device operable to order unloading of the compressor when air pressure level in the reservoir tank reaches a preset level. An electrically operated valve is pneumatically connected to the intercooler and connected electrically to the pressure sensing device of the governor, with the electrically operated valve being effective to exhaust air pressure in the intercooler when the valve receives an unload signal from the pressure sensing device. The compressor is driven by an electrical motor having one or more speed configurations, with transition occurring between one configuration and another when the compressor is unloaded. The electrically operated valve is effective to unload the intercooler at the time of speed configuration transition to reduce undue motor and electrical contactor heat and thus increase life expectancy of the motor and contactors.

Title: Light fixture with actuator-retained switch
Inventor: AUSTIN BARRY G
IPC: B60Q3/02
Filed: 1998-08-27
Abstract: A light fixture with an actuator retained switch particularly adapted for surface mounting to a variety of supporting surfaces, e.g., the interior of a recreational vehicle, includes a housing, lens and mounting structure for suspending the switch within the housing. The mounting structure consists of a pair of mutually spacedinternal walls which contain slots adapted to receive the edges of the switch. The switch is positioned between the two internal walls such that the operating member of the switch is in position to readily engage the switch actuator. Engagement of the switch operator and actuator serves to lock them together and retain both upon the housing. To operate the switch, the user manipulates the actuator, which is locked to the operating member of the switch, by sliding the actuator from side-to-side.

Inventor: PRIEVE JOHN F
IPC: G01N21/33
Filed: 1998-11-12
Abstract: An improved apparatus and method for measuring the concentration of hydrogen peroxide vapor or gas in a sterilization chamber.  The hydrogen peroxide is measured spectrophotometrically in the ultraviolet region between 200 and 400nm.  Because water vapor does not absorb in the ultraviolet region, it does not interfere with the determination of the concentration of the hydrogen peroxide vapor.  Although organic compounds have absorbances in the ultraviolet region, the organic compounds are removed by evacuating the sterilization chamber to low levels before doing the hydrogen peroxide determination.  The ultraviolet light source is either a low pressure mercury vapor lamp with an emission at 254 nm ora deuterium lamp with an optical filter selective of 206 nm light.  A movable gas cell can be used to measure the hydrogen peroxide concentration at various areas in the sterilization chamber.  The measurement system can be combined with a feedback loop to control the concentration of hydrogen peroxide in the sterilization chamber.
