The float may be located within a shroud 48. The system aims to provide a delayed operation of a fill valve, and also to ensure full refilling of the cistern following a partial flush, due to the rate of water and air flowing into and out of the shroud and float during a flush cycle introducing delays into the cycle. The chamber may be located annularly around a central channel. Also claimed is an entire float assembly and fill valve including the variable float.

Title: Processing Display Data
Inventor: Richard Akester
IPC: H04N19/63
Filed: 2019-07-19
Abstract: A method for compressing and decompressing display data comprising a group of pixels forming an image frame, which may be a frame of a video. A wavelet transformation is performed on the group of pixels to obtain a general approximation coefficient (a DC value), and a plurality of detail coefficients (AC values) for the group of pixels. When compressing the data, it is determined whether to prioritise transmission of the DC coefficient over transmission of the AC coefficients based on availability of resources and/or based on a time since AC coefficients for a corresponding group of pixels were previously transmitted. If transmission of the DC coefficient is to be prioritised over transmission of the AC coefficients, the method comprises either: transmitting the DC coefficient only, or compressing at least one AC coefficient, which may include quantisation, so as to be more compressed than the DC coefficient and then transmitting the DC coefficient and the at least one compressed AC coefficient. An advantage of the invention is that if the client device receives a DC coefficient only, it can retrieve AC coefficients from previously received frames. The previously received AC values may be stored locally (S4N1, fig 4b).

Title: A continuous type process method to increase the rate of reaction between solids, liquids, and gasses per area of the land occupied by two reactors
Inventor: PRAKASHKUMAR NARASIMHAMURTHY
IPC: F16N7/12
Filed: 2020-03-19
Abstract: Two inline tower gas wet scrubbers wherein each scrubber has a moving bed of solids 0010 that is conveyed from the top to the bottom of the towers via a plurality of perforated moving floors 003 arranged one above the other. Wherein the moving floors are mounted on plenums 004 that extend from the internal walls of the towers. A liquid 008 is sprayed from the top of each tower, wherein the liquid washes the exhaust gas, capturing particle matter and absorbing acidic gases and heat. As the liquid falls under gravity, the liquid is filtered through the solids. Exhaust gas e.g. containing CO2 enters the first scrubber 001 above the bottom plenum and travels upwards over the moving bed towards the outlet at the top of the scrubber, whilst being washed by the falling liquid. The warm carbonated solids and liquid that exit the first reactor are fed into the top of the second reactor 002, whilst the gas exiting the first reactor enters the second reactor via the plenums/ducts that support the moving floors thereby distributing the gas throughout the reactor.
