| 20100303206 | Online energy dispersive X-ray diffraction analyser - An on-line EDXRD analyser including (i) a housing defining an analysis zone and having a passageway through it to allow transport of material in a process stream to pass through the analysis zone, (ii) a collimated source of polychromatic X-rays, (iii) an energy-resolving (ER)X-ray detector, (iv) a primary beam collimator disposed between the source of X-rays and the (ER)X-ray detector comprising an annular slit which defines an incident beam of polychromatic X-rays to irradiate a portion of the analysis zone, (v) a scatter collimator disposed between the primary beam collimator and the ERX-ray detector, the scatter collimator comprising an annular slit which defines a diffracted beam of X-rays scattered by the material to converge towards the ERX-ray detector, and (vi) a detector collimator comprising a conical opening which further defines the diffracted beam of X-rays scattered by the material. The ERX-ray detector measures an energy spectrum of the diffracted X-rays at a predetermined diffraction angle defined by the relative positioning of (ii) to (vi), and where one of (iv) and (v) comprises an aperture arranged to enable a detector to measure the transmission of a direct beam of X-rays through the material. | 12-02-2010 |

| 20110277657 | Projectile for Use in a Barrel with a Plurality of Stacked Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile includes a chamber containing a propellant charge, with an exit from the chamber for release of propulsion gases into the barrel. A seal blocks the exit and is opened by ignition of the propellant within the chamber but is resistant to gases produced by ignition of propellant in other projectiles in the barrel. The exit and seal are provided in a range of different forms. The exit may be an aperture in a wall of the chamber with the seal as a moveable barrier, such as a valve-like structure, for example. The seal may also include a rupturable or deformable barrier across the aperture. Alternatively the seal is a thin barrier around the charge such as a wax coating and the exit involves a disintegrable character of the barrier. The seal may also be an inherent property of the geometry of the chamber. | 11-17-2011 |

| 20100043628 | Projectile for a Stacked Projectile Weapon - Clips for use with projectiles and projectile stacking systems in which individual projectiles are clipped together to form a stack are disclosed. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and unclipped as required by the user. | 02-25-2010 |
| 20100282111 | Propellant Sealing System for Stackable Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field.

| 20100132536 | FILE CREATION PROCESS, FILE FORMAT AND FILE PLAYBACK APPARATUS ENABLING ADVANCED AUDIO INTERACTION AND COLLABORATION CAPABILITIES - A file creation process, file format and playback device are provided that enables an interactive and if desired collaborative music playback experience for the user(s) by combining or retro-fitting an ‘original song’ with a MIDI time grid, the MIDI score of the song and other data in a synchronized fashion. The invention enables a music interaction platform that requires a small amount of time to learn and very little skill, knowledge or talent to use and is designed to bring ‘mixing music’ to the average person. The premiere capability that the file format provides, is the capability for any two bars, multiples of bars or pre-designated ‘parts’ from any two songs to be mixed in both tempo and bar by bar synchronization in a non-linear drag and drop fashion (and therefore almost instantaneously). The file format provides many further interaction capabilities however such a remixing MIDI tracks from the original song back in with the song. In the preferable embodiment the playback means is a software application on a handheld portable device which utilizes a multitouch-screen user interface, such as an iPhone. A single user can musically interact with the device and associated ‘original songs’ etc or interactively collaborate with other users in like fashion, either whilst in the same room or over the Internet. The advanced inter-active functionality the file format enables in combination with the unique features of the iPhone (as a playback device), such as the multitouch-screen and accelerometer, enable furthered intuitive and enhanced music interaction capabilities. The object of the invention is to make music interaction (mixing for example) a regular activity for the average person. | 06-03-2010 |
