Title: Mutant WASP proteins
Inventor: DEVRIENDT KOENRAAD
IPC: C12N15/12
Filed: 2001-02-28
Abstract: There is disclosed a new disease, X-linked severe congenital neutropenia (XLN), caused by a novel L270P mutation in the conserved GTPase binding domain of the Wiskott-Aldrich syndrome protein (WASP). <I>In vitro</I>, the mutant protein is constitutively activated toward the Arp2/3 complex through disruption of an autoinhibitory domain in the wild type protein, suggesting that loss of WASP autoinhibition is a key event in XLN. These findings highlight the importance of precise regulation of WASP in hematopoietic development and function, since impairment versus enhancement of its activity give rise to distinct spectra of cellular defects and clinical phenotypes.

Title: Using electrical resistance to monitor the moisture content of ceramic material for bust sculpture manufacture.
Inventor: HURLEY PETER DAVID
IPC: B28B7/34
Filed: 2002-12-03
Abstract: A three dimensional bust sculpture is produced by coating a pre-shaped former 1 made of low density thermoplastic with a wet ceramic material 2. The moisture content of the ceramic material is monitored by means of its electrical resistance, using connections 4 and computer 5. The former must be removed before the sculpture over contracts in order to prevent cracking. The assessed wetness of the ceramic material determines when the computer initiates the delivery of a chemical to dissolve the former by means of devices 3 and 6, or, alternatively, energises an electrical heater (8, figure 7) to degrade the former. Upon removal of the former the sculpture is transferred to a kiln for firing.

Title: Pressure reducing valve system
Inventor: TROW STUART WILLIAM
IPC: G05D16/16
Filed: 2003-09-03
Abstract: A pressure reducing valve system is disclosed that modulates its outlet pressure such that the pressure increases as flow rate increases, for example to compensate for head losses arising from flow in a water supply installation. The system includes a pressure reducing valve (PRV) 10, a pilot valve 12 for operating the PRV, and a pressure feedback stage 40. The pressure feedback stage 40 includes a gate valve 42 that creates a head loss that increases with flow through the PRV. The head loss causes water to flow in a bypass pipe 44 that incorporates a venturi 46. The pilot valve 12 is controlled by pressure at the venturi 46. This pressure decreases as flow rate increases, thereby causing the pilot valve 12 to increase the output pressure of the PRV as flow rate increases.

Title: Camera combining images produced by astroid scanning.
Inventor: BARTH JOCHEN
IPC: G02B26/08
Filed: 2003-12-04
Abstract: The image field of a focal plane array (FPA) camera is enlarged by combining scanned partial images to form a final, combined image. As shown, four partially overlapping 256-pixel image regions 1 - 4 are combined to form a bigger, 456 pixel image. Scanning for the final image is performed by two rotary refracting prisms (A and B, Figure 3), providing a cycloidal scan pattern in the form of an astroid: that is, scanning in a generally square shape but having concave sides between the vertices, as shown. The prisms are continuously rotated, at respective angular velocities, in opposite directions. A further apparatus (3, Figure 2) is provided to project alignment marks onto the image scanned by the camera (1, Figure 2). The step-scan method using rotating prisms apparently simplifies the electronic scanner triggering, reduces energy used, lowers heat dissipation and prevents unwanted torque effects; the scanner may be particularly useful for missile applications.

Patent GB-2394321-A (GB)
Title: A display
Inventor: CHISHOLM ANDREW
IPC: G04B19/20
Filed: 2002-08-23
Abstract: The display makes use of the alignment of respective radial lines extending on two or more co-axially aligned discs (26, 28) in which the number of lines on each disc is differ-ent such that only one line of one of the discs can be aligned with anyone of the lines of the other of the discs at a single point in time. Rotation of the discs relative to each other causes the alignment of the lines of respective discs to rotate about the co-axis and when the discs are relatively rotated according to the passage of time, the alignment provides an indication of that time.

Title: Etching a film or substrate using a sacrificial layer
Inventor: VARGHESE RONNIE P
IPC: H01L21/311
Filed: 2004-07-30
Abstract: Etching into a substrate or thick film is controlled by introducing a sacrificial film to gauge the depth of the etch. An etch stop film is deposited on a first film. A second film is deposited over the etch stop film. A photomask is deposited on the second film and used to pattern the second film and etch stop film. The photomask is then stripped and a trench etched into the first film using the second film as a sacrificial film to terminate the etch. The depth of the trench can be controlled by optical endpointing the etch of the sacrificial film on the etch stop film. The process can be repeated to create a device having stepped trenches.
