Title: Manufacturing a rigid foam board
Inventor: MCCABE THOMAS
IPC: B29C44/32
Filed: 2002-01-11
Abstract: A rigid foam board is manufactured by leading a lower foil substrate 2 from a supply reel onto a conveyor bed 8. The lower substrate 2 has side edges 10, 11 which are guided progressively upwardly by a guide means 15 on each side as the substrate 2 is led along the conveyor bed 8 to form upturned side lips 10a, 11a. Liquid foam reactants are then applied to the lower substrate through a longitudinally arranged laterally movable spray bar 20. On application, some of the liquid foam reactants impinge against the inner faces of the upturned side lips 10a, 11a to optimise the filling of the foam reactants in the region of the side lips 10a, 11a. The upper substrate 3 is led over the foam reactants to form a panel sandwich which is heated in a fixed gap oven. The foam reactants expand in the oven forming a continuous length of panel which is side trimmed by side edge cutting saws 25 and cut to desired length by a transversing saw.

Title: Using a power related to a received beacon and estimates for non-beacon codes for automatic gain control in a receiver
Inventor: ANDERSON NICHOLAS
IPC: H03G3/30
Filed: 2002-08-01
Abstract: Automatic gain control (AGC) and synchronisation acquisition by a communication unit in a wireless communication system, e.g. a TDD-CDMA system such as the Universal Mobile Telecommunication System (UMTS) system, is described. AGC is performed using a downlink beacon function, for example a power level (P beacon ). Also discussed is amplitude-equalising (limiting) performed as part of synchronisation acquisition and the use of separate AGC processes for different stages of synchronisation acquisition. One AGC process uses a peak power (P(k)) of a received signal over a frame. Another AGC process uses a peak power (P(k)) of a received signal over only a portion of a frame, the portion comprising an initial synchronisation code. Another AGC process uses measurements of a received signal (P 0 (k)) taken in a downlink beacon timeslot. These processes tend to provide tolerance to a varying number of codes (M) transmitted on a timeslot-by-timeslot basis and robust initial synchronisation in the presence of strong uplink interference.

Title: Catheter for controlling the advancement of a guide wire
Inventor: NEET JOHN M
IPC: A61M25/09
Filed: 2001-01-29
Abstract: A catheter for controlling the advancement of a guide wire includes a catheter body having a central lumen, a first side lumen and a second side lumen. A pair of opposing control wires extend the length of the catheter body through the side lumens. The catheter body includes a proximal portion coupled to a less rigid distal portion. A control handle coupled to the proximal ends of the control wires produces opposing motion of the control wires along the length of the catheter body, causing the distal portion of the catheter body to deflect relative to the proximal portion of the catheter body, thus directing the guide wire. In one embodiment, the control handle includes a guide wire advancement mechanism for controlling the advancement of the guide wire through the catheter.

Title: Liquid sample take-up device
Inventor: PAI SU-CHENG
IPC: B01L99/00
Filed: 2002-07-10
Abstract: The liquid sample take-up device comprises two layers of concentric tubing. An outer tube has a fluid take-up end for selective immersion in a liquid to be sampled, and a liquid connection spaced from the fluid take-up end adapted to receive a chemical reagent under pressure, creating a reagentflow toward the take-up end. An inner tube is disposed within the outer tube and has an open end adjacent to the outer tube take-up end. The inner tube is adapted to fluid connect to a negative pressure source, higher than the reagent pressure, to create a fluid flow within the innertube in a direction away from the open end, whereby sampled liquid and reagent are mixed adjacent the inner tube open endand within the outer tube take-up end. When the outer tube take-up end is not immersed in a liquid to be sampled, airis drawn into the outer tube take-up end and into the innertube open end, creating a series of air bubbles, each bubble-separated by a volume of reagent.
