Title: Pile installation method
Inventor: GLEADOWE JOHN RICHARD YORKE
IPC: E02D7/28
Filed: 2007-12-03
Abstract: A method for facilitating the installation of a pile or column 1 in a supporting medium 2 comprises creating spaces or voids (7, Fig 2) within the medium, adjacent to the lower end 3 of the pile. These spaces or voids receive or accommodate material displaced by the lower end of the pile or column, as it is caused to penetrate said medium as it descends to a required depth. The pile or column may be advanced by using successive stages of forcibly driving the pile or column downwards into the supporting medium. The spaces or voids may take the form of a ring or radial array (6, Fig 2) of relatively spaced holes around the central axis of the pile or column. The spaced holes may be produced by indexing or rotating a drilling head 4 around the central axis.

Title: Probability based method of playing a game or voting
Inventor: SHIMSHI EZRA
IPC: A63F3/06
Filed: 2009-07-27
Abstract: In a method of playing a game in which aplayer attempts to select a winning choice, a plurality of choices are provided, including a winning choice and several losing choices, the identities of which are unknown to the player. The choices are labelled, the player notionally divides the labelled choices into a small group and a large group, and the player then selects a single choice. At least one choice is eliminated such that two choices are left, including the winning choice and the player selected choice. The player then checks which of the small and large group the remaining choice, which isn't the player selected choice, is from. If the remaining choice is from the small group, the player maintains their original selected choice. If the other surviving choice is from the large group, the player withdraws their original selected choice. The method relies on the principle that the probability of the winning choice being among the large group is greater than the probability of its being among the small group. The method may be employed in single or multiplayer games, e.g. game shows or internet games. A method of voting is also disclosed.

Title: Method for diagnosing the integrity of a swirl generating system for an internal combustion engine
Inventor: BROSIO FULVIO
IPC: F02B31/06
Filed: 2009-09-14
Abstract: An i.c. engine has a number of pivotable intake air swirl controlling flaps 123 on a common swirl shaft 13 which is driven by an actuator 14 via a kinematic chain eg of meshing gears 15. Rotation of the shaft 140 in opposite directions A,B in a nominal angular range NAR, eg 90°, is controlled on the basis of signals from a shaft position sensor 141 and engine operating conditions, eg load. Rotation of the shaft 140 is limited by internal mechanical stops 142 and 143 to a potential angular range PAR which is greater than, eg double, that of the nominal angular range NAR. The invention provides two further, external, mechanical stops 17, 18 acting on the swirl shaft 13 to limit rotation of the shaft 13 to a control angular range CAR which is equal to or greater than NAR but less than PAR. If a sensed angular end position of the shaft 13 corresponds to one end of CAR the kinematic chain is deemed to be working properly but if it corresponds to one end of PAR a failure signal is generated. The diagnosis routine may be repeated in the opposite sense of rotation.

Title: Process for maintaining the activity of catalysts in the catalytic oxidation of organic compounds
IPC: B01J23/847
Filed: 1954-04-06
Abstract: In the production of anthraquinone by the oxidation of anthracene with an oxygen-containing gas in the presence of a vanadium-containing catalyst, the catalyst is regenerated, or its activity kept constant, by neutralizing acid compounds which are formed in the catalyst during the oxidation (see Group III).  The catalyst may be a heavy metal vanadate, e.g. ferric vanadate, or a vanadium catalyst prepared according to Specification 786,374. In one method of carrying out the invention, ammonia or a volatile amine is added to the oxygen-containing gas used in the oxidation process, either when activity of the catalyst has declined, or from the outset of the process.  Specifications 156,244 and 156,245, [both in Class 2 (iii)], also are referred to.ALSO:A vanadium-containing catalyst used for the oxidation of anthracene to anthraquinone is regenerated, or its activity kept constant, by neutralizing acid compounds which are formed in the catalyst during its use.  The catalyst may be a heavy metal vanadate or a vanadium catalyst prepared according to Specification 786,374.  Neutralization is effected by treatment with an alkali metal or alkaline earth metal hydroxide or carbonate, aqueous ammonia, or a solution of an alkali metal alcoholate, e.g. potassium methylate.  In examples, a catalyst prepared according to Specification 786,374 is regenerated (a) by grinding with potassium carbonate and graphite, moistening with methanol, water and glycerine, and pelletting; or (b) by standing with a methanol solution of potassium hydroxide for 16 hours, draining off the solution, evaporating methanol from the catalyst, and roasting. Alternatively, ammonia or a volatile amine may be added to the oxygen-containing gas used for the oxidation, either when activity of the catalyst has declined, or from the outset of the process; an example relates to the treatment in this way of a ferric vanadate on pumice catalyst. Specifications 156,244 and 156,245, [both in Class 1 (i)], also are referred to.
