Abstract: A separating screen conveyor for sorting a material into fractions having different distributions of a property of the particles or items. The conveyor screen has a row of shafts mutually spaced in a conveying direction, each shaft carrying a row of axially spaced discs for intermittently urging material on the sorting conveyor upward and in the conveying direction. The discs are releasably clamped to the shafts which have strips oriented in longitudinal direction of the shafts on circumferential surfaces of the shafts. The strips have toothed surfaces. Openings of the discs each have a recess closely fitting to the strips and teeth in engagement with the teeth of the toothed surfaces of the strips. The pitch of the teeth of the strips is smaller than the maximum widths of the discs in the longitudinal direction of the shaft.

Abstract: A sorting screen for sorting material comprises a row of rotatable, driven shafts mutually spaced in a conveying direction. Each shaft extends transversally to said conveying direction and carries carrying a row of radially extending rotor bodies for intermittently urging material on the sorting screen upward and in conveying direction. The rotor bodies of each of said rows are mutually spaced in longitudinal direction of the respective shaft by spacers. Each spacer is a tubular spacer and each rotor body is provided with at least a recess or a number of projections retaining a respective end face of a respective tubular spacer.

Abstract: A shaft for a rotary star screen apparatus has a shaft body having a series of axially spaced star connectors and a series of stars, mounted to the star connectors. Each one of these stars has a plurality of circumferentially distributed star members each elongate in a direction having a component radially away from the shaft body. The star connectors each have a plurality of circumferentially distributed star member connectors. Each of these star members is a separate part, individually and detachably mounted to one of the star member connectors. An apparatus equipped with such shafts is also described.

Abstract: A method of forming a multi purpose drilling for degassing a coal seam that is to mined, the method including the steps of drilling a primary borehole from a surface into a zone above the coal seam, such that at least a portion of the primary borehole extends substantially parallel to the coal seam, and drilling at least one secondary borehole, wherein the least one secondary borehole extends from the primary borehole into the coal seam.

Abstract: A portion of a circulatable air permeable conveyor member (6) constitutes a sorting track (7) inclined from a lower end (8) to an upper end (9). A vacuum (11) is maintained underneath the sorting track (7). The sorting track (7) is arranged for entraining a portion of the material to be sorted with the conveyor member from a drop zone (15) of the sorting track (7) towards the upper end (9) of the sorting track (7) and allowing another portion of the material to be sorted to descend from the drop zone (15) towards the lower end (8) of the sorting track (7). A sweeper (2) is arranged between the drop zone (15) and the upper end (9) for sweeping flat material entrapping non-flat material off the entrapped non-flat material. A method for sorting flat material such as paper or plastic film from a stream of waste material is also disclosed.

Abstract: An apparatus for perforating and deforming containers is equipped with a perforating rotor (6) including sharp perforating elements on an outer circumference for perforating containers in a transport path. The perforating rotor (6) is rotatable about an axis of rotation on a first side of the transport path (4) and oriented transverse to the transport direction (5). A pressing rotor (7) for pressing the containers against the perforating rotor (6) is rotatable about an axis of rotation on a second side of the transport path (4), opposite the perforating rotor (6) and oriented transverse to the transport direction (5) and comprises circumferentially distributed fingers (8) each projecting in a direction radial and circumferential to the axis of rotation of the pressing rotor (7).

Abstract: Method of and system for selecting a position in an image sequence. A representation (200) of the image sequence is displayed, together with a position indicator (206) configured to be moved along the representation (200). The position in the image sequence is selected in correspondence to a present position of the position indicator (206). A collection of key frames is obtained, each key frame being associated with a portion of the representation (200). From this collection of key frames a current key frame (212) is displayed whose associated portion comprises a present position of the position indicator (206). Indications (205) of the locations of the key frames in the collection may be shown as well.

Abstract: The invention relates to pourable water and oil containing emulsions comprising an aqueous phase and gas bubbles, whereby said gas bubbles are substantially dispersed in the aqueous phase. Emulsions according to the invention show increased stability.

Abstract: The invention relates to food products comprising an aqueous phase and gas bubbles, whereby said gas bubbles are substantially dispersed in the aqueous phase, and whereby said gas bubbles have a mean diameter size distribution with a maximum below 10 &mgr;m and whereby said aqueous phase comprises a compound capable of forming at least a partial coating around said gas bubbles. Food products are for example cheese, frying fats, dressings, margarines.

Abstract: A method and system for registering a user preference for a program (201) in at least one of a collection (221) of preference profiles for recording a set of user preferences. An input (211, 212) representing the user preference for the program (201) is received. For each preference profile from said collection (221) a score for the program (201) is determined, said score indicating the degree of agreement of the program (201) with said preference profile.

Abstract: A food product is described comprising an aqueous phase and gas microbubbles substantially dispersed in the aqueous phase which gas microbubbles have coating and a mean diameter size distribution with a maximum below 10 &mgr;m, wherein the coating substantially consists of protein, wherein the pH of the aqueous phase is from 2.5 to 6.0.

Abstract: It is known to add anti-spattering agents to spreads and other frying fats so as to reduce the spattering tendency. Anti-spattering agents include, nitrogen, salt, calcium chloride or phosphates, and emulsifiers such as egg yolk and lecithin. Oxidised bean oil is known to be effective against primary spattering but ineffective against secondary spattering. An improved anti-spattering agent effective against both primary and secondary spattering, comprises a mixture of a thermally oxidised vegetable oil such as "blown bean oil" and a source of phosphatidyl choline, preferably "Cetinol".
