A tyre granulator 1 for granulating rubber in a recycling process includes a granulation chamber (24, Figure 2) housing a rotor 11, removably attached to stub shafts 12,13. The rotor has a plurality of flying blades (18a,18b) distributed circumferentially around, and longitudinally along, the rotor. Granulation chamber 24 has an infeed aperture for receiving input tyre material, a longitudinal fix...

A flip type mobile phone is described. It comprises a first part and a second part hinged relative to one another and movable between open and closed positions. When the first and second parts are opened, a communication channel is established between the mobile phone and a base station. When they are closed, the communication channel is cut off in a first set of circumstances, but maintained in a...

A method of pulling yarn from a plurality of bobbins 1 mounted on a creel, includes mounting a plurality of bobbins side by side in a row and locating adjacent a first bobbin a guide eye or tube 6 for guiding yarn from another bobbin in the row, preferably the adjacent bobbin in the row. The tubes 6 or eyes are mounted on arms 5 which in addition to receiving the tubes are formed with slots to acc...

A delivery for a rotary printing press with a circulating conveyor system in which the sheets fixed in gripper closures are released while being deposited on to a sheet pile has a blown air device arranged above the sheet pile for assisting the sheet deposition. At least a part of the blown air unit (6) is variable in its position so that the distance between blown air unit (6) and the upper edge ...

A drill bit insert has a cylindrical barrel, a bevel on one end, an interface therebetween, and a cutting tip opposite the bevel. The bevel and interface contact the entrance to a hole in the drill bit and facilitate the transition of the barrel into the hole. A high quality surface finish on the bevel and interface enhance the durability and retention of the insert in the drill bit. The surface f...

A magnetic actuator for adhering a moving piece (36) to a pole piece (38) separated therefrom by an air gap when an electrical circuit (34) is excited, at least one intermediate piece (42) being movably arranged in said air gap between the moving piece and the pole piece, and defining, in the absence of excitation (inoperative state), gaps (e1, e2) between the intermediate piece(s) and the moving ...

A scraper assembly for removing the collected solids component of a feed material from an interior wall surface of a centrifugal separator bowl comprises a supporting shaft positioned within the bowl along a vertically disposed longitudinal axis. The supporting shaft is pivotal between a stowed position and an operational position. At least two longitudinally spaced scraper blades are attached to ...

Therapeutic oligonucleotide analogues, which have nuclease resistance and improved cellular uptake are provided. Replacement of phosphorodiester inter-sugar linkages found in wild type oligomers with four atom linking groups forms unique di- and polynucleosides and nucleotides useful in regulating RNA expression and in therapeutics. Methods of synthesis and use are also disclosed.

The method consists of subjecting the organ to pre-exposure with a low dose of rays, creating in the field of the pre-exposure image a multicellular image in which each cell represents the mean signal level of a predetermined number of pixels of the detector, selecting from the columns the cell of minimum signal level most distant from a reference point, establishing about this cell a band paralle...
