Abstract: INFUSION PUMP SYSTEM          Abstract of the Disclosure An infusion pump system is described containing a valved cassette which is used as a pumping chamber for conducting fluid from an upstream portion to a downstream portion of the system.  The removable cassette contains magnetically biased valves at both ends.  Externally mounted magnets bias the valves within the cassette to provide an opening of the inlet valve and closing of the output valve during the fill cycle and closing of the inlet valve and opening of the outlet valve during the pump cycle.  Free flow of infusion fluid is allowed when the valved cassette is removed from the pump mounting member which houses the actuating magnets and the reciprocating actuator for the pumping chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           Oil  shale,  coal,  inert  heat  transfer material and other carbon-containing solids of varying sizes are preheated with a gas in a transfer line by first separating the solids into a plurality of size fractions and then separately introducing the size fractions into the transfer line at predetermined distances from the transfer line inlet.  The predeter-mined distances are inversely related to the size of the particles comprising each fraction of solids so that the fraction of solids containing the largest particles is produced nearest to the gas inlet and the fraction of solids containing the smallest particles is introduced at a point furthest away from the trans-fer line inlet.  Normally, solids withdrawn from the transfer line will have been heated to a temperature below which any liquids or gases evolve and are ready for further processing in downstream conversion units such as oil shale retorts, coal gasifers and the like.

Abstract: ABSTRACT        In a method and apparatus for production of rastered printing forms with rasters having arbitrary screen angles and screen width, picture elements are exposed on a recording medium by means of a recording element whose expo-sure beam is switched on and off by a control signal.  The recording medium is sub-divided into a plurality of surface elements which are exposed or not exposed by the exposure beam as a function of the control signal.  All surface elements exposed in a screen mesh of the rotated raster to be recorded form a respective picture element. At least two matrices in the form of matrix memories are provided, the individual matrix elements thereof having a raster threshold or a raster hill allocated to them.  The raster thresholds represent the periodic basic structure of a screen mesh and are different for at least one tonal range in the individual matrices.        During recording, those matrix elements in the indi-vidual matrices whose positions within the respective matrices correspond to the position of the swept surface ele-ment within the corresponding screen mesh are identified for each surface element swept by the recording element within a screen mesh.  The raster thresholds of the identified matrix elements are called in.  Controlled by a random generator, one of the called raster thresholds is randomly selected and compared to an image signal value acquired by means of scann-ing the original.  The control signal for the exposure beam is derived from the comparison, whereby a decision is made on the basis of the signal comparison as to whether the corresponding surface element is to be exposed or not as part of a picture element.
