Title: Folding and joining composite boards
Inventor: TOMES KEVIN
IPC: B32B3/12
Filed: 2006-03-17
Abstract: A flat composite board such as honeycomb cardboard comprising two outer rigid material surfaces separated by an internal filling material is folded and / or joined by cutting the board from one side to create vertical and horizontal cuts which intersect at right angles to form one or more equally spaced rectangular cuts without removing material and leaving the other surface intact, applying pressure to on or both edges of the board either side of one or a plurality of cuts and folding and/or joining the board. Various of the cuts may be depressed (see for example11 and 12 in figure 2b). Alternatively the board comprising two sections may be folded and / or joined by removing the inner surface and internal filling material such that a dovetail section 2 of intact board is left in the centre of a first area of the second section 4, the dovetail section comprising a protruding shoulder d and removing the inner surface of the first section 1 to leave a second area of rigid material for forming at the base of the dovetail section a rectangular void 3 providing a cavity where the board is to be folded. The inner surface of rigid material and internal filling material of another section 6 of a second board or of the other end of the same board may be removed and the protruding material d with the removed material of the second board or the other end of the same board. In forming a chair 701 (see figures 7 and 8) 2 opposite ends of a composite board are symmetrically cut and curved in opposition and a single sheet of rigid board 703 is slotted through a void in the centre 702 and anchored at either end through a slot 704 and fixed by dovetail joint 705 and glued. Products such as a storage box, an office dividing system, cupboard, plant container, table, bed, children's playhouse (Wendy house), dolls house, pet box, pet home, rabbit burrowing tube, pet casket, ashes casket, coffin, bird box, bee house, exhibition stand, protective packaging materials or insulating materials for pipes, temporary shelter or lining for an excavated earth channel may also be made.

Title: A mass analyzer utilising a plurality of axial pseudo-potential wells
Inventor: PRINGLE STEVEN DEREK
IPC: H01J49/42
Filed: 2006-11-01
Abstract: A mass analyser is provided comprising an ion guide 2 comprising a plurality of electrodes having apertures through which ions are transmitted in use. A plurality of time-averaged or pseudopotential corrugations, barriers or wells are created along the axis of the ion guide 2. The amplitude or depth of the pseudo-potential wells, barriers or corrugations is inversely proportional to the mass-to-charge ratio of an ion (see Figs 2 and 3). One or more transient DC voltages are applied to the electrodes of the ion guide 2 in order to urge ions along its length. The amplitude of the transient DC voltages applied to the electrodes is increased with time and ions are caused to be emitted from the mass analyser in reverse order of mass-to-charge ratio.

Title: Microfluidic fluid handling apparatus
Inventor: HAEBERLE STEFAN
IPC: F04B43/14
Filed: 2007-01-19
Abstract: A microfluidic fluid handling apparatus comprises a rotating body 10 having at least one fluid handling structure 12 which is delimited by a flexible member 14 attached to the body 10 and formed to interact with fluid in the fluid handling structure 12. The flexible membrane 14 contains a first actuating component, e.g. a paramagnetic steel lamina 30, which is attracted to or repelled from a stationary second actuating component, e.g. magnet 32, when the rotating body 10 rotates relative to the stationary magnet 32. By attracting/repelling, via the lamina 30, the flexible membrane 14 a pumping action is produced which causes fluid to be pumped. A motor 24 is attached to the rotating body 10 by a shaft 22 and fixture 20. The motor 24 rotates the body 10 so as to introduce a centrifugal force in the pumping action. In other embodiments the fluid handling structure 12 may contain a valve chamber (42, fig 2) connected to a pumping chamber (46) and the motor 24 may be replaced with driving means which effects accelerated translation of the body 10.

Inventor: CALVIN DAVID CHARLES
IPC: F16B5/06
Filed: 2007-05-10
Abstract: A fastening device for securing an apertured article to an apertured support by passing the device through co-aligned apertures, the device comprising a fastening element and a retaining element. The fastening element (fig. 2) comprises a planar shoulder portion 8, a neck portion 10 extending therefrom, a lip portion 12 on the neck portion and an aperture-engaging means 14 located on the shoulder portion.

Title: Lattice reduction for detection of MIMO systems using an LLL-based algorithm
Inventor: MILFORD DAVID
IPC: H04B7/08
Filed: 2008-02-18
Abstract: A method of applying lattice reduction to a signal bearing information, e.g. for use in Multiple-Input Multiple-Output (MIMO) detection. The method is based on the Lenstra-Lenstra-Lovasz (LLL) algorithm but makes use of the parity value of a row sum of an inverse of a lattice reduction matrix and, on the basis of the parity value, controls determination of quantisation of observations to a reduced lattice. Hence, efficiency of the LLL-type computations is improved as there is no need for the explicit computation of the row-wise sum. A possible hardware implementation of the quantisation of one component is illustrated in the figure.
