Title: Pulley block with linked pulleys
Inventor: BOWMAN GEORGE HENRY PETER
IPC: B66D3/04
Filed: 2005-09-23
Abstract: A pulley comprises first 112 and second 114 pulley wheels which have a ratchet arrangement 132 and 136, 138 which allows relative rotation in opposite directions but constrains them to rotate together in one direction. When both parts of the loop 149 are pulled, both pulleys rotate in opposite direction giving a gear ratio of 1:1. When the tail leading onto pulley 114 is pulled with the other fast in a cleat 128, pulley 112 remains static and pulley 114 moves giving a gear ratio of 2:1. When the cleat tail is pulled, both pulleys are forced to rotate with a gear ration of 9.5:1. The rope or chain is connected to a block 150 and preferably used on a sailing yacht to eg move a boom (38, Fig 2) of a mainsail. One of the pulleys can be drum shaped, as shown, or both can be V-shaped and the groove bottom can have a faceted profile (222, Fig 22) or the walls can have offset apertures to increase grip. One pulley can be braked (278, Fig 32) or the cleat attached to a fiddle block (250, Fig 28). Various axle and bearing bush arrangements are also disclosed as are a number of other alternative pulley and block arrangements (Figs 35-61). Also claimed are first and second pulleys which prevent relative movement in one direction and allow it in another or in which movement of one pulley in one direction causes equal and opposite movement of the other pulley in a second direction.

Title: Apparatus and method for fluid flow measurement with sensor shielding
Inventor: MAUTE ROBERT E
IPC: G01F/
Filed: 2004-09-30
Abstract: Methods and apparatuses for detecting radial flows of conductive fluid are provided. In an embodiment of the present invention, shields are used to prevent or reduce circulating electrical currents from causing a voltage difference that would adversely affect the measured voltage difference between two adjacent electrodes. The shields may be a conduit through which conductive fluid may flow. Groups of sensors, e.g., two or more, may be placed within the shield. The shields may have any cross-section shape. Generally, once the circulating electrical current flow between the electrode pairs is substantially reduced or eliminated, only the voltage difference from the localized induced electric field remains. This way, a true induced voltage may be measured, and thus an accurate value for the fluid velocity may be determined.

Title: Imaging wells drilled with oil based muds
Inventor: TABANOU JACQUES R
IPC: G01V3/24
Filed: 2004-08-26
Abstract: A method for determining a formation property comprises injecting a first current into a formation by energizing a first current injector electrode (81), measuring a property of a first current returning to a first current return electrode (83) disposed at a distance from the first current injector electrode, and measuring a property of a second current returning to a second current return electrode (84) disposed proximate the first current return electrode. The method further includes injecting a second current into the formation by energizing a second current injector electrode (82), measuring a property of a third current returning to the first current return electrode, and measuring a property of a fourth current returning to the second current return electrode. The formation property is then determined from a difference measurement derived from the property of the first current, the property of the second current, the property of the third current, and the property of the fourth current. The method is performed while drilling a well (MWD) using an oil based mud (OBM). The use of two current injectors is to cancel the effect of tool standoff.

Title: Tandem mass spectrometry system
Inventor: SATOH TAKAYA
IPC: H01J49/00
Filed: 2007-03-26
Abstract: A tandem mass spectrometry system is offered which decelerates precursor ions while suppressing the range of the kinetic energies and spatial spread of the precursor ions. The spectrometry system has a first mass spectrometer for creating and extracting precursor ions. The ions are introduced into a decelerating electric field at a slight angle to the direction of the electric field which is formed by first through third electrodes. An accelerating electric field perpendicular to the decelerating electric field is applied at the instant when the ions arrive at the midpoint between the second and third electrodes at which the velocities of the ions in the direction of the decelerating field are zero. Then, the ions are entered into fragmentation means. Consequently, the range of the kinetic energies of the precursor ions is narrowed. Hence, the range of the kinetic energies of the product ions produced from the precursor ions by the fragmentation means is reduced.

Title: Display device for an entertainment machine
Inventor: GERRARD PETER
IPC: G07F17/32
Filed: 2008-07-04
Abstract: A display device for an entertainment machine, such as a gaming machine, shows a central rectangular play area and various indicators 16, 17, above and beneath the play area. In one embodiment, the display shows a flat surface 20 having a two-dimensional matrix of symbols 19. The surface 20 moves to produce a changing display of multiple symbol combinations. The movement gives the impression of flying over the surface 20 with the surface 20 tilting and moving towards and away from the play area. The movement takes place at a relatively slow speed so that the player can clearly see the symbol combinations. The final stage of the movement which involves bringing the surface 20 towards the window in flat disposition so that ultimately only three symbol combinations can be seen, occurs via a convoluted course such that the final display is not fully known until the movement terminates. When the movement stops, the symbols aligned with the payline or win line 15 give an outcome used in the game. The movement of the matrix of symbols provides anticipation and entertainment for the player.
