Abstract: A multicomponent crystal (or co-crystal) comprising a first active pharmaceutical ingredient and a second active pharmaceutical ingredient. The multicomponent crystal is formed/sustained by non-covalent interactions between the nitrogen-containing heterocycle alpha-substituted with an amino group of the first active pharmaceutical ingredient and a carboxylic acid group of the second active pharmaceutical ingredient, suitably as well as other further non-covalent interactions with other H-bond forming groups. The multicomponent crystal may provide an improved multidrug dosage form comprising lamotrigine and valproic acid as the first and second active pharmaceutical ingredients, respectively. A pharmaceutical composition comprising a therapeutically effective amount of the multicomponent crystal and a pharmaceutically acceptable excipient, and a method of forming the multicomponent crystal, are also provided.

Abstract: A method of processing an active pharmaceutical ingredient, the method comprising passing a precursor composition comprising the active pharmaceutical ingredient and a solvent through a twin screw extruder wherein the twin screw extruder is heated at ambient pressure.

Abstract: The present invention provides a fertiliser comprising nutrients adsorbed onto a core material comprising a carbonate mineral. Also provided are methods of producing a solid fertiliser, the method comprising adsorbing nutrients onto a core material comprising a carbonate mineral. The invention also provides a method for treating waste material by anaerobic digestion to produce a nutrient rich liquor and adsorbing nutrients from this liquor onto a core material comprising a carbonate mineral. Also provided are the uses of a carbonate mineral for adsorbing phosphorus from anaerobic digestion liquor and for the control release of phosphorus from a fertiliser.

Abstract: A food transport system and method are provided for transporting a packaged food item from one floor of a restaurant, such as a cooking or preparation floor, to another floor of the restaurant, such as a serving or dining floor. The food transport system includes a conveyor that transports a food-item supporting carrier along a closed-loop pathway. The carrier includes a rack with a plurality of spaced-apart food-item support members. On an upward portion of the pathway, the carrier passes a pick-up station having a pick-up rack with a plurality of spaced-apart food-item support members, the carrier support members passing between the pick-up support members to pick up the food item. On a downward portion of the pathway, the carrier rack passes through a drop-off rack in a similar manner, thus depositing the food item on the drop-off rack.

Abstract: A process for preparing hydroxylapatite from a calcium carbonate-containing algae comprising the steps of: (a) converting at least some of the calcium carbonate in the algae to calcium oxide without changing the porosity of the algae; and (b) reacting the so-formed material of step (a) with phosphate ions in water.

Abstract: A storage mechanism utilizing a single data recorder from which multiple channels of compressed video data may be simultaneously accessed. The data access to and from the data recorder via a single data access path takes place at a higher data rate (f.sub.1, f.sub.2) than the data rate (f.sub.3, f.sub.4) at which that compressed data needs to be decoded to support a video signal. A video router is used to direct the reproduced data stored within two data channel buffers to respective JPEG decoders where they are decompressed into a signal suitable for driving two digital monitors. In operation, a segment of compressed video data for one channel is recovered from the data recorder and stored within one of the buffers from which it is continuously read at a lower data rate (f.sub.3, f.sub.4). The data recorder then cues to another part of the medium from which data for the second channel is reproduced and stored within another buffer. The process is then repeated.

Abstract: A programmable memory cycle is entered on a keyboard and set by a remote system control processor. Each local processor controls access to memory boards in accordance with the set memory cycle. When the memory cycle is divided into four memory access slots, the processor can provide, in each memory cycle, three read slots and one write slot, two read slots and two write slots, or one read slot and three write slots. When used for processing video signals, the arrangement can process three video channels, or more if expanded by the provision of further memory boards and local processors.

Abstract: In apparatus for spatially interpolating between lines of a digital video signal, to produce interpolated lines, a supersampler horizontally interpolates between samples of the signal to produce a supersampled signal consisting of the original samples and interpolated samples located between them. Block matching circuits each determine, for each sample of the supersampled signal, the extent of matching between two blocks of N.times.M samples (N=number of lines and M=number of samples), the blocks being vertically offset in opposite directions with respect to a line to be interpolated, and being horizontally offset in opposite directions with respect to a predetermined sample position. Each block matching circuit produces a matching value for a respective different horizontal offset.
