Abstract:
According to a first aspect of the present invention there is provided a process for preparing a particulate solid comprising the steps i) to iv): i) providing a dispersion of polymer particles in a liquid medium, said polymer being obtained or obtainable by the copolymerisation of at least the monomers in components a) to d): a) 45 to 90 parts of one of more hydrocarbyl (meth) acrylates each having a homopolymer Tg of from 90 to 130° C. and having no hydrophilic groups; b) 10 to 55 parts of one or more ethylenically unsaturated monomers each having homopolymer Tg of below 90° C. and having no hydrophilic groups; c) 0 to 40 parts of one or more styrenic monomers having a homopolymer Tg of at least 90° C. and having no hydrophilic groups; d) 0 to 10 parts of one or more ethylenically unsaturated monomers each having at least one hydrophilic group; wherein all the parts are by weight; ii) associating the particles to form clusters of particles; iii) optionally stabilising the clusters; iv) heating the clusters above the glass transition of the polymer.
Abstract:
A method for detecting a two-dimensional bar code pattern using a bar code pattern reader, the bar code pattern being in the form of a matrix of rows and columns of data cells of either a first or second colour representing encoded data bits, and containing a set of at least two predetermined locating symbols at predetermined positions within the bar code pattern, wherein the method comprises the steps of: receiving a two-dimensional image containing the pattern, analysing the image to identify potential occurrences of the locating symbols within the image, validating the potential occurrences of locating symbols by analysing the potential occurrences to identify any set of occurrences whose size and relative positions within the image are consistent with the predetermined positions of the locating symbols within the bar code pattern, thereby identifying a set of locating symbols, and identifying the location of the bar code pattern within the image on the basis of the positions of the identified locating symbols. An apparatus for carrying out the method, and systems which utilise the bar code pattern, are also disclosed.
Abstract:
An antenna assembly is disclosed. The antenna assembly includes an externally-located vehicular mirror housing and an antenna assembly. The externally-located vehicular mirror housing includes a cable exit passage. The antenna assembly includes at least one antenna element mounted on a circuit board. The antenna assembly is located within the externally-located vehicular mirror housing. The cable exit passage passes an antenna cable extending from the circuit board and into the vehicle cabin.
Abstract:

Abstract:
A convertible cargo container system having individual components that provide a table or work surface. The container system includes a pair of foldable side panels and a pair of rigid end panels coupled to the ends of each side panel to form an enclosed container. A back panel is hingeably connected to a top panel to form one side panel, and a bottom panel is hingeably connected to a front panel to form the other side panel. Each of the front, back, and bottom panels has opposing coupling ends. The interior surface of each end panel has a coupling track that receives the coupling ends of the front, back, and bottom panels. Each of the side panels may be unfolded to provide a table or work surface. Additionally, each of the side panels have retracting or folding legs attached to the interior surface of the side panel that may be extended or unfolded to support the table or work surface. A vehicle hitch coupling support is attached to the bottom of the container.
Abstract:
An instrument supporting crane for supporting a camera or the like, the crane being readily assembled, disassembled, and shipped. The crane includes a boom to which a nose assembly is pivotably coupled, and a base unit to which the boom is pivotably coupled. The boom is preferably constructed of a series of sections such that the length of the boom may be varied, depending upon the application. The boom sections are coupled by complementary channels such that the section slide together. An additional mechanical coupling, such as a screw may be provided. Preferably, the boom is a hollow elongated structure with openings extending therethrough to allow the passage of air to minimize movement of the nose assembly when the crane is used in high winds. A platform assembly having a monitor tray for supporting a monitor may be provided at a tail section of the boom. The monitor tray may be pivotably coupled to the tail section and the base unit such that the angle of the monitor varies depending upon the relative positions of the tail section and the base unit. The base unit is likewise readily assembled and disassembled. The base unit includes a head, a plurality of legs and a dolly. A center tie-down rod extends between the head and the dolly such that when the rod is shortened, as by tightening a sleeve, the head and dolly are drawn towards one another and a compressive force is placed on the legs to secure the base unit together.
Abstract:
A directional power detector mounted between the power amplifier and antenna which supplies audio frequency output signals indicative of forward and reflected power, circuitry for summing and converting the output signals from the power detector means to a DC potential proportional to the magnitude thereof and a transistor connected in shunt at the input of the power amplifier and controlled by the DC potential for controlling the peak envelope power at the antenna.
