Signatures are fed successively onto a conveyor with their backs facing rearwardly and the distance between two adjacent backs less than the max. signature width feedable, moving past suction units to form a stream of signatures with each sheet having a front corner projecting laterally outwardly of the stream. The signature are parted by folding back the front corner of each sheet of at least hal...

A system (10) for determining the level of a fluidised bed uses a minimum number of pressure sensors. A pressure sensor (12) is positioned at the base of the bed, another pressure sensor (14) is positioned at approximately 2.44 m (8 ft) above a distributor plate, and other pressure sensors (16, 18) are positioned at intermediate locations therebetween. The measurements from the sensors are selecti...

PURPOSE:To take a copy which has superior resolution and visibility at a high speed by forming a mask plate corresponding to characters and images of an original on an intermediate sheet and exposing a photosensitive pressure- sensitive recording sheet surface through the plate. CONSTITUTION:Light from a light source 3 after scanning an original 1 is passed through a primary-color separation filte...

PURPOSE:To make a coordinate input simple and accurate by arranging a line-shaped deflecting elements group on a light beam and its optical path and also arranging a reflection optical member opposite to the above-mentioned elements and providing a photodetector, etc. CONSTITUTION:An optical coordinate input device is provided with a light source (laser diode) and a deflecting plate 11, a beam spl...

PURPOSE:To permit time-out and hourly occurrence sequence and processing sequence of transaction to agree and to prevent transaction from becoming invalid due to processing delay by executing the processing of time-out as that of transaction. CONSTITUTION:The transactions 4a-4d and a time-out transaction 4t from a terminal are connected to a queue, and are put on standby. A transaction processing ...

The invention relates to a method for the deformational transformation of aluminum and its alloys comprising the steps of deforming the aluminum in the solid state and annealing the deformed aluminum at a temperature at which recrystallization occurs. The recrystallization temperature of the aluminum is raised and the grain size is minimized by adding to the aluminim 5 to 1000 ppm uranium prior to...
