Some of the ribs are internally reinforced by rigid metal members which extend orthogonally between hollow box-section members which define a sub-frame for reinforcing the four edge regions of the frame. The orthogonal members are secured at their ends to the sub-frame. The ends of the sub-frame members are joined at the four corners of the sub-frame. In this way not are only the edge regions of the frame reinforced internally but so also are some of the orthogonally intersecting ribs, so as thereby to produce a rigid frame for the screen.Type: ApplicationFiled: May 17, 2010Publication date: September 2, 2010Applicant: UNITED WIRE LIMITEDInventor: Graham Alexander Robertson

Publication number: 20100116720Abstract: The invention relates to an apparatus for sifting feedstock, comprising: a. a static sifter that has a ventilated bottom which is oriented at an angle to the vertical and is penetrated by sifting gas; b. an inlet for feeding the feedstock to the ventilated bottom; c. an outlet for the coarse material; d. a dynamic sifter that is mounted downstream and encompasses at least one rotor with rotor blades and a horizontal rotor axis; e. at least one outlet for the sifting gas loaded with fine material; and f. a housing inside which the static and the dynamic sifter are arranged. The housing area surrounding the dynamic sifter is designed as a housing spiral such that the sifting gas flows against the rotor in a substantially tangential direction. The rotor rotates counter to the direction of flow of the sifting gas in the housing spiral.Type: ApplicationFiled: May 5, 2009Publication date: May 13, 2010Applicant: POLYSIUS AGInventor: Christoph Mendelin

Publication number: 20100071918Abstract: A box-shaped beach-cleaning trailer is configured to be loaded with, and collectively carry beach-cleaning equipment and a litter collection station. The beach-cleaning equipment are towed by a vehicle to collect litter on the sands. The litter collected by the beach-cleaning equipment is collected in the litter collection station. The trailer includes a pair of rail members disposed on upper edges of the respective opposite side wall portions such that the rail members face each other with an opening therebetween. A sieve unit is detachably mounted on the rail members, and is configured to move a back-and-forth direction along the rail members. The sieve unit is moved in a back-and-forth direction manually; or by using a driving mechanism including a drive wheel, a driven wheel, and a connecting rod arranged between the sieve unit and the driven wheel, for separating colleted litter of various sizes from sand.Type: ApplicationFiled: September 15, 2009Publication date: March 25, 2010Applicant: Honda Motor Co., Ltd.Inventors: Kosuke Asao, Jun Nakajima, Tatsuo Masuda
