Title: Data processing apparatus and method
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: G06F7/58
Filed: 2008-10-17
Granted: 2012-10-17
Abstract: A data processing apparatus is arranged to map input data symbols to be communicated onto a predetermined number of sub-carrier signals of Orthogonal Frequency Division Multiplexed OFDM symbols. The predetermined number of sub-carrier signals is determined in accordance with one of a plurality of operating modes and the input data symbols are divided into first sets of input data symbols and second sets of input data symbols. The data processing apparatus comprises an interleaver operable to perform an odd interleaving process which interleaves the first sets of input data symbols on to the sub-carrier signals of first OFDM symbols and an even interleaving process which interleaves the second sets of input data symbols on to the sub-carrier signals of second OFDM symbols, such that while the input data symbols from the first set are being read from locations in the interleaver memory, input data symbols from the second set can be written to the locations just read from and when input data symbols from the second set are being read from the locations in the interleaver memory, the input data symbols from a following first set can be written to the locations just read from. Furthermore, when the number data symbols which can be carried by the sub-carriers of an OFDM symbol in one of the plurality of operating modes is half or less than half of the number of data symbols, which can be carried in an operating mode which provides the most number of data bearing sub-carrier signals per OFDM symbol, the data processing apparatus is operable to interleave the input data symbols from both first and second sets in accordance with the odd interleaving process on to the first and second OFDM symbols, and to change the permutation code which is used to form the addresses from one OFDM symbol to another.

Title: Absorbent article with elastic net-like substrate having a layer of fibres prebonbed
Inventor: COLES PETER
IPC: A61F13/00
Filed: 1993-03-11
Abstract: In an absorbent article, such as a diaper or incontinence briefs, an elastic member (60) comprising a net-like elastic substrate (62) to which fibers (64, 66) are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangling, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is located between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amount of adhesive.
Patent IT-1216643-B (IT)
Inventor: RUCKSTUHL WILLI
IPC: E01C5/06
Filed: 1988-03-29
Granted: 1990-03-08
Abstract: The set of paving stones consists of stones (11-16) having in each case in plan view six lateral limiting faces (1-6, 17-22). Four of these limiting faces (1 and 4, 3 and 5; 18 and 21; 19 and 22) are each placed parallel to one another in pairs, whereas the remaining two (2 and 6; 17 and 20) together form an acute angle. The stones (11 - 13) are laid alternately in the straight line. This gives rise to a joint pattern with butt joints which are not perpendicular to the bedding joints. The butt joints are moreover formed from two mutually oriented wedges and are therefore irregular compared with the bedding joints. The bevelled limiting faces  (2, 6) make it possible for the stones (11 - 13), depending on the desired bevel angles, to be laid in curves whose radii can be as small as desired, the wedge-shaped joints gradually closing. The stones (14 - 16) serve as a supplementary curve set and permit the laying of Roman arrow patterns as well as an Archimedean spiral. The set of paving stones can be laid simply and quickly without a cutting of the stones.

Title: Therapeutic N-acetyl-S-cysteine prepn.
Inventor: FRANCIA GIORGIO
IPC: A61K/
Filed: 1984-04-13
Granted: 1990-03-30
Abstract: In a telecine chain, the scanning raster is rotated by applying a magnetic field perpendicular to the axis of the electron beam, and the distortion introduced by such rotation is compensated for. A rotate coil is located about the scanning tube the coil formed so that current passing through it induces the magnetic field and thus effects the rotation of the raster. The degree of rotation is within limits dependent on the current, and the direction of rotation is dependent on the direction of current flow. There is pref. an Absolute Angle Generator which has an input common with the input which controls the current through the Rotate Coil and which provides outputs for the compensation functions. Focus compensation is effected by applying a stimulus to the focus system which is based on the degree of rotation being effected.

Abstract: An immunologically active peptide conjugate is described formed from the union of a synthetic peptide having an amino acid sequence equal or analogous to that of at least one immunodominant epitope of the circumsporozoitic protein of Plasmodium, with the purified protein derivative of tuberculin (PPD). Said conjugate is able to stimulate with high efficiency the production of antisporozoite antibodies of Plasmodium even in the absence of adjuvants. The antibody response towards this immunogen is not restricted genetically and is particularly effective when the animal is vaccinated with bacillus Calmette-Guerin before administration of the conjugate. Said peptide conjugate is particularly useful in the preparation of antimalaria vaccines.
