Abstract: A light-emitting diode is used both for receiving data from an operator to change the logic state of a device and for displaying the entered data back to the operator. Current is selectively applied to the diode to display the data, but on an alternate basis the photo-current produced in the light-emitting diode by surrounding illumination is sensed and the data are received by detecting the fall-off in the photo-current caused by the operator covering the light-emitting diode. This technique is advantageously employed for the input and display of ink slide settings for a rotary printing machine by using a light-emitting diode matrix or bar graph display subject to finger-tip control by the operator. The diode matrix is scanned by repetitively and sequentially inhibiting the lighting current to the individual light-emitting diodes so that they may be sequentially connected to a photo-current monitoring circuit via a multiplexer under control of a clock circuit.

Abstract: A method and apparatus for measuring the particle concentration of suspensions, especially suspensions having high particle concentration. Light is directed into the suspension, and light scattered by the particles, preferably back-scattered light, is detected at a first and a second position located at different distances from the position where the light is sent into the suspension. The concentration is then calculated as arctanh (Ef/En), or preferably   <IMAGE>   where En is the detected light intensity at the first relatively near position and Ef is the light intensity at the second relatively far position. The intensity of the light directed into the suspension is controlled by means of the relation EfxEn=1. The mean value of Ef and En is then compared with 1 in order to determine whether the calculated concentration corresponds to the concentration of the suspension being measured.

Abstract: The invention is for a die for a cleaning tool for the removal of surplus pieces which are obtained when punching blanks from sheet material. The invention is primarily intended for use when punching cardboard sheet in the production of e.g. packages. In a first operation thereby the pieces (28) are not completely punched out from the sheet (29) but are still to some extent connected to each other and to those parts of the sheet (29) which shall be removed to give holes of various kinds. The surplus pieces (28) which are positioned between the blanks often have the shape of thin strips. Before the continuing handling of the punched blanks these surplus pieces (28) shall be removed. According to the invention for this purpose is used a die (24) having holes (3-5) through which the surplus cardboard pieces (28) shall pass. Parts of the hole (3-5) through which a surplus piece (28) shall pass is covered by tabs of flexible material (7,8) which is present on the upper surface of the die board (24). There is also a corresponding upper die which has prutruding members (25) preferably having the shape of pins or discs, by which means the punched parts are removed from the blank and pushed beyond the tabs (7,8) through the hole (3-5). Thereby that the punched parts are clamped between the prutruding members of the upper die (25) and the flexible tabs (7,8) it is secured that the surplus pieces (28) are entirely freed and removed from the blank.

Abstract: A method for handling containers in which containers are stacked using a moveable crane with a travelling part such as a trolley (8) arranged to lift, move and land a container (7) on a stacking target (15) in a stack comprising a least one ground container (1). The method is characterised by the steps of measuring the horizontal position of the stacking target (15), determining the horizontal position of the ground container (1), and comparing the relative positions of stacking target (15) and ground container (1). An overlap is developed from the relative positions of the stacking target (15) and the ground container (1), and compared to predetermined limits. If the overlap is within limits a desired landing position (25) on the stacking target (15) is selected for the container (7). Advantages include automatic stacking, faster stacking, safer stacks and dense packing of stacks in a container terminal.
