Title: Soil anti-compaction system
Inventor: BOWIE DEAN
IPC: A01G23/00
Filed: 2006-06-07
Abstract: A soil anti-compaction system comprises a multiplicity of modules, each comprising an areal distribution of tubular open ended substantially identical tubular cells 11 connected by bridging formations 13 which extend between adjacent said cells, the several cells forming an integral array with the top and bottom edges respectively, of the cells contained in parallel planes. Means enable a multiplicity of arrays each as aforesaid to be connected side by side to constitute a soil anti-compaction system of desired dimensions. Whilst serving to oppose compaction of the soil around the tree root system, under adventitious loads arising, for example, as a result of traffic liable to bear down on the soil at the site of the tree system, the conformation, as described and depicted in the specification, of the modules is such as not to inhibit, to any substantial extent, the ability of the root system to propagate.

Inventor: GARDNER RICHARD JAMES ERNLE
IPC: G09F7/02
Filed: 2007-02-05
Abstract: A display sign comprises a substrate sheet 10 of, preferably foamed, plastics PVC material. The front face of the substrate sheet 10 comprises a surface layer 11 including a plasticiser. The plasticiser renders the front face of the substrate sheet 10 adherent.

Title: Encrypted Mobile TV broadcast with encrypted content key while key encryption key is delivered over phone network
Inventor: PRIESTLEY MARK
IPC: H04N7/167
Filed: 2007-09-27
Abstract: In the art is known to encrypt <B>11</B> broadcast content <B>13</B>, such as TV programmes, with a traffic encryption key (TEK). This TEK is then encrypted with a session encryption key (SEK) and the encrypted TEK <B>15</B> is broadcast with the content. The SEK is separately distributed <B>43</B> to user terminals <B>1</B> over a point to point network, such as a mobile phone network <B>3</B>, where is used to decrypt the TEK and thus the content. The SEK may be protected with user terminal public/private keys during this distribution. The known SEK is a symmetric key and is therefore vulnerable when sent to broadcasters for encrypting the TEK. The invention proposes making the SEK and asymmetric public/private key pair, such that only the public part SEK_pub <B>27</B> is sent to the broadcaster. Hence even if it is compromised the TEK and the content cannot be accessed without the private part SEK_priv.

Title: Saturated vapour turbine system
Inventor: COURTNEY WILLIAM ALEXANDER
IPC: F01D1/00
Filed: 2008-04-22
Abstract: A device for converting the latent heat stored in a flowing stream of saturated vapour into useful work, comprising a linear array of sets of turbine blades or separate turbines, characterised by the vapour processing capacity of each successive set of turbine blades or turbine units decreasing in volume, in a proportionate manner that motivates the saturated vapour pressure to remain constant as the stream passes through the array, and vapour condenses out as latent heat is released. The device may have adjustable baffles 1,2,3 to create extra viscous drag at low vapour rates. The drag causes an increase in evaporation which is observed as an increase in vapour volume. The baffles only come into operation at low saturated vapour flow rates.
