Abstract: An apparatus for use in tie treatment of substrates with a solid particulate material, said apparatus comprising a housing having mounted therein a rotatably mounted drum having an inner surface and an end wall, and access means for introducing said substrates into said drum, wherein (a) said drum comprises storage means for storage of said sold particulate material; (b) said drum has at least one elongate protrusion located on said inner surface of said drum wherein the elongate protrusion extends in a direction away from said end wall, wherein said elongate protrusion has an end proximal to the end wall and an end distal to the end wall; (c) the or each elongate protrusion comprises a collecting aperture and a collecting flow path to facilitate flow of said solid particulate material from the interior of said drum to said storage means, wherein said collecting aperture defines the start of a collecting flow path, and wherein the same elongate protrusion further comprises a dispensing aperture and a dispensi

Abstract: A light railway system comprising two parallel rails (12) each having a base portion (14) with a flat bottom, an upward-extending web (15), and a railhead (16), and resting within a respective trough structure (20). The trough structure (20) comprising multiple trough units (22) arranged end to end, with blocks (24, 26) that fit between the web (15) of the rail (12) and side portions of the trough unit (22) so as to locate the rail (12) within the trough structure (20). The system also includes multiple spaced-apart rigid ties (28) that interconnect the trough structures (20), so the rails (12) are at a desired separation. Inserted junction plates (54) may be used to hold successive trough units (22) in alignment.

Abstract: Aspects relate to a drum (10) for rotatably mounting in an apparatus for use in the treatment of substrates with a solid particulate material; a method of treating a substrate comprising agitating the substrate in a drum (10); and a kit for converting an apparatus to comprise the drum (10).

Abstract: An apparatus, method and kit for use in the treatment of substrates with a solid particulate material, said apparatus comprising a housing having mounted therein a rotatably mounted drum having an inner surface and an end wall and access means for introducing said substrates into said drum, the drum preferably having and elongate protrusion (1) located on said inner surface of said drum, wherein ? (a) said drum comprises storage means for storage of said solid particulate material; and ? (b) said drum comprises a first collecting flow path to facilitate flow of said solid particulate material from the interior of said drum to said storage means when said drum rotates in a first collecting direction, characterised in that said drum comprises a second collecting flow path to facilitate flow of said solid particulate material from the interior of said drum to said storage means when said drum rotates in a second collecting direction, wherein said second collecting direction is in the opposite rotational directio

Abstract: A tooth cutting guide or tooth ridge lap guide for processing at least one prefabricated artificial tooth from a set of prefabricated artificial teeth using a subtractive processing method, the tooth cutting guide comprising a base body, at least one retainer for receiving and positioning the at least one prefabricated artificial tooth, which is formed in the base body, wherein an inner surface of each of the at least one retainer form fits to a first surface area of one of the at least one prefabricated artificial tooth from the set of prefabricated artificial teeth, and at least one through hole which is located in the at least one retainer, wherein the at least one through hole exposes at least a part of a basal surface or an occlusal surface of the one of the at least one prefabricated artificial tooth if inserted into the corresponding retainer.

Abstract: A computer-implemented method of creating and maintaining an online store, comprising the steps of establishing a master account at a system server; establishing a first account, the settings of the first account being stored in a database, wherein the first account is initiated through the master account; establishing a second account, the settings of the second account being stored in the database, wherein the second account is initiated through the first account, the second account having a link to an online store; relating the master, first, and second accounts such that purchases made at the online store are recorded and tracked at the master, first, and second accounts and control settings of the second account are determined through the master account; processing purchases made at the online store by the master account; and sharing revenue from the online store purchases by the master, first, and second account.

Abstract: Photoactivatable dendrimers and hydrogels formed therefrom include dendrimers to which polymer chains (e.g. polyethylene glycol, PEG) have been conjugated; and reactive photoactivatable groups attached to terminal functional groups of the polymer chains (e.g. hydroxyls of PEG). Exposure to a suitable wavelength of light activates the photoactivatable groups, which then crosslink with one another, thereby forming a hydrogel. The hydrogel may also include one or more agents of interest; or, in some embodiments, nanoparticles containing one or more agents of interest may be dispersed in the hydrogel. These formulations are well-suited for sustained or prolonged delivery of active agents, e.g. for the treatment of glaucoma by the sustained delivery of anti-glaucoma agents directly to the eye.

Abstract: Drinking water bottle return apparatus having a bin, a door or receiving tray movable between an open position and a closed position, a first sensor detecting when the door or receiving tray in the open position, a second sensor detecting a drinking water bottle entering the bin, and a receipt dispenser that dispenses a receipt in response to detection by the second sensor of a drinking water bottle entering the bin within a predetermined time period after detection by the first sensor of the door or receiving tray in the open position.
