Title: Computer virus detection using a Boyer Moore search algorithm
Inventor: SEATON ROGER
IPC: G06F21/56
Filed: 2006-10-10
Abstract: Computer files are checked for the presence of virus signatures using a Boyer Moore search algorithm. Instead of comparing the first block of a virus signature with the first block of a computer file, the search is performed in reverse order by comparing the last block 5 of the signature 2 with a corresponding block of the computer file 1 and then working backwards from right to left. Depending on the results of the comparison the signature is shifted to the right 4 by a certain amount. In figure 2 block "Y" of the file does not appear anywhere within the signature and so the signature is shifted to the right by an amount equal to its length and the process repeated. Thus not every block of the computer file is checked. Signature offsets may be used to specify the point at which a search should begin. Other embodiments are concerned with displaying graphical information. The information may be locally stored advertisements displayed in accordance with associated scheduling information. A user selection may cause a purchase request to be transmitted. Information may be displayed at the same time as a virus scan is performed. The progress of the virus scan may be displayed.

Title: Reduction in stage movement reaction force in an electron beam lithography machine
Inventor: HARRIS PAUL GEORGE
IPC: H01J37/20
Filed: 2006-10-12
Abstract: An electron beam lithography machine 10 comprises: a base structure in the form of a plinth 14; a plurality of legs 22 which preferably include pneumatic damping elements 23 for supporting the plinth relative to a support surface 24, the legs defining a support plane A for the plinth; an electron beam column 11 carried by the plinth; and a stage 17,18 arranged in a vacuum chamber at the plinth to be moveable substantially parallel to the support plane and to carry a workpiece 13 to be acted on by an electron beam generated by the column. The centre of gravity 25 of the stage, which can be movable along X and Y axes of a co-ordinate system of the machine, is disposed in or adjacent to the support plane. This results in a reaction force to the stage movement being oriented in the support plane or in an adjacent parallel plane, thereby preventing said reaction force from inducing a significant amount rocking of the column which would otherwise disrupt the writing process.

Title: A fence post driving apparatus
Inventor: HORGAN CORNELIUS
IPC: E04H17/26
Filed: 2007-02-16
Abstract: A post driving apparatus 1 is mounted on a tractor T and has a frame 2 mounted on the tractor three-point linkage. The frame 2 has a pillar supporting a weight 3 and an impact plate 20. A low-level post guide 5 has a front guide plate 6 a pair of brackets 10 and a hinged rear guide plate 7. Double acting hydraulic rams 8, 9 within box sections of the frame 2 are pivotally connected to the front guide plate 6 at opposite transverse ends thereof. The rams 8, 9 are driven by the tractor hydraulic system with individual ram control. They allow rotation of the guide 5 about a vertical axis through a large range of angles. In addition, they allow translational movement of the guide 5 forwards and backwards. The guide allows post driving where the fence line is at any of a range of angles with respect to the tractor direction, and so fencing along a narrow road is possible, the tractor facing along the direction of the road. It also allows individual post orientation control from the spool valves, and supports the post throughout the driving process.

Title: Address generation polynomial and permutation matrix for DVB-T2 32k OFDM sub-carrier mode (de)interleaver
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: G06F7/58

Abstract: The standards for DVB-T/H specify (de)interleaving symbols to/from OFDM subcarriers. It further specifies an interleaving address generator that comprises a linear feedback shift register and a permutation matrix operating on the shift register bits. The DVB-T/H specifications include 3 modes with approximately 2, 4 and 8 thousand sub-carriers, and interleaver address generators for these are known. A proposed DVB-T2 specification includes three new modes with 1, 16 and 32 thousand sub-carriers. The invention specifies a polynomial to be implemented in the LFSR and a permutation matrix for the 32k mode.

Title: Improvements in and relating to prepayment mechanism for electricity meters, and thelike
IPC: G07F15/08
Filed: 1946-04-01
Abstract: 613,950. Prepayment mechanism for meters. CROMPTON PARKINSON Ltd., and WICKHAM, A. H. April 1, 1946, No. 10070. [Class 27] Price-change mechanism.-A prepayment meter price-change gear included, for example, between a basic charge motor and the quantity mechanism, comprises driving and driven members which are engaged for equal adjustable portions of successive cyclic periods, whilst once during a predetermined number of cyclic periods a period of engagement is adjustably increased, decreased or otherwise modified, or there is an additional adjustable period of engagement. This modified or additional period provides for fine adjustment in price, whilst the remaining equal periods provide for coarse adjustment. In the mechanism shown, driving and driven members 24 and 25 of a clutch are engaged and disengaged by axial movement of a coaxial arm 26 which is continuously rotated by the driving member 24 through reduction gears 29, 30. Once in each revolution the arm 26 passes a fixed strike-in pin 52 and then an adjustable strike-out pin 54, this causing a forward and return axial movement of the arm 26, and engagement of the clutch for a period determined by the adjustment of the strike-out pin 54. A cam 33, Fig. 4, is also driven by the clutch driving member 24 through further reduction gears 31 and at a still lower speed than the arm 26. At a fixed point in its revolution, cam 33 releases a supplementary strike-in member 58 which then becomes effective to cause an additional engagement of the clutch terminated by engagement of the arm 26 with an additional strike-out pin 59. Adjustment of the strike-out pins 54 and 59 consequently provides coarse and fine adjustment respectively in the price. The pins are carried by coaxial arms 55, 60 secured to superposed coarse and fine adjustment dials 56, 61 movable respectively in steps of threepence and a farthing, the reduction ratio between the cam 33 and arm 26 being 12/.1. A modified construction has one strike-in pin only, and the fine adjustment cycle has a single period of engagement which is adjusted by an additional strike-out pin brought into action by the cam 33 to be effective in place of the coarse adjustment pin 54 during that cycle. The mechanism includes a two-speed rate-change gear between the constant-speed motor 10 and clutch, comprising gears 18, 19 on a shaft 17, which is shifted axially to bring either gear alternatively into mesh with a respective driving gear 15, 16. Movement of the shaft 17 is effected by cams 63 engaging its ends and provided on arms 62 secured to a shaft 64 which can be rocked to either position of adjustment by an operating lever 65 extending over the dials 56, 61. The drive from the clutch is taken to the meter quantity mechanism through a differential gear 34 which transfers the drive to an arrears storage spring when the quantity mechanism stops at zero credit.

Title: Improvements in process for purification of hydrocarbons
IPC: C07C7/11
Filed: 1956-04-03
Abstract: Hydrocarbons, such as the diolefines, butadiene, pentadiene, isoprene, chloroprene, piperylene, methylpentadiene and 2,3-dimethyl, 1,3-butadiene, are purified by removing small quantities of oxygen or oxygen and nitrogen, with a non-aqueous liquid absorbent which selectively dissolves the hydrocarbon so that the impurities may be removed and the pure hydrocarbon is obtained by reducing the pressure on the enriched absorbent to "flash" off the pure hydrocarbon.  A mineral seal oil or furfural are used as liquid absorbents.
