Abstract: Abstract A signal clamping and sampling circuit wherein signals to be sampled are applied to a voltage amplifier (52).  The output of the voltage amplifier is coupled in common to the inputs of first (53) and second (57) matched operational transconductance amplifiers (OTA's).  During an initial clamping reference interval, the first (53) OTA conducts to form a feedbacks clamping network for establishing input and output reference bias conditions for the voltage amplifier.  The second (57) OTA conducts during a subsequent sampling interval for processing signals to be sampled.  The output reference bias of the voltage amplifier determines substantially identical input bias conditions for both the first and second OTA's, thereby significantly reducing the likelihood of signal processing offset errors being produced as between the clamping and sampling intervals when the first and second OTA's are respectively conductive.  A level shifting network may be used for applying the signals to the voltage amplifier for providing signals compatible with the input requirements of the amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed are a novel photosensitive recording material and a method for using the recording material in the production of planographic printing plates.  The recording material comprises a support and a negative-working photosensitive layer that contains a diazonium salt  polycondensation  product  as  the  photosensitive compound  and,  in  addition,  a  colorless  inorganic pigment  which  is  insoluble  in  water  and  organic solvents  and which has  an average particle diameter from 1 to 20 /um.  The pigment is present in a quantity from 0.01 to 2% by weight, relative to the non-volatile constituents of the layer, and is evenly distributed in the layer.   Due to the pigment content, a rough layer surface is formed, which has the effect of reducing the time required for creating a vacuum in a vacuum frame into which the recording material is mounted.  The pre-sence of  the pigment  in the layer  also produces an improved tonal rendering in the print obtained.

Abstract: Abstract of the Disclosure An apparatus for cleaning the air from a paint spray booth by removing paint particles entrained therein in which water flows across downwardly converging bottoms walls of the booth through a nozzle extending substantially the entire length of the booth to prevent paint from adhering to them.  To improve efficiency and insure the water prevents adherence of paint particles, the nozzle has a rounded entry. The water is atomized and mixed with the paint particles in a restricted section of the nozzle which is connected to the entry by ledges which direct the water across the inlet of the restricted section to improve atomization and mixing of the water and to minimize the noise produced by the operation of the nozzle.  The mixture is discharged from this nozzle through a restricted orifice at a high velocity to impinge on a pool of water below the nozzle which separates and removes particles of paint from the air.

Abstract: TITLE PRESSURE LEACHING OF URANIUM ORES IN A CHLORIDE MEDIUM                       INVENTORS George P. Demopoulos Gordon M. Ritcey ABSTRACT OF THE DISCLOSURE Concurrent dissolution of both uranium and radionuclides from ores thereof has been achieved by leaching under oxygen pressure with an alkaline earth metal chloride preferrably calcium chloride solution acidified with HCl.   Sulphide ores lead to sulphate ion build-up, excess of which is removed by autogenous alkaline earth metal sulphate precipitation: this has been found to allow increased solubility and extraction of radlonuclides particularly radium.  Leaching times are short e.g. 4 hrs, such that radium precipitation or adsorption after dissolution is minimized.  Uranium recoveries of above 95% and radium recoveries above about 90% have been obtained. The extracted radionuclides can be disposed of separately, leaving the tailings environmentally inert and suitable for backfill.

Abstract: Abstract The process for the fixture of suspension elements, particularly suspensions loops, to sausages by means of sealing components, e.g. clamps, foresees that the sausage sheath be restricted by a binding tool (12) which can be set to three positions. The binding tool (12) is open in the initial position between two sausage filling processes so that a suspension loop (16) can be fed through the opening (48). During the sausage filling process an intermediate position is adopted in which one part (54) of the binding tool already holds the suspension loop (16). The binding tool (12) is closed in the shape of a ring at least during the filling procedure for large calibers of sausage. Subsequent to the filling process the binding tool then executes the binding movement.          Fig. 1

Abstract: Abstract of the Disclosure A Fluid System With Selective Differential Pressure Control Fluid systems having modulating pressure relief valves are normally needed in systems having clutches that require smooth enggement.  It is also desired in many systems to maintain a difference in pressure levels between the fluid in different clutches, such as, speed and directional clutches during initial engagement in order to ensure that only one of the clutches absorbs the initial load.  In order to reduce power losses and improve system efficiency, it is desirable to reduce the pressure level of the higher clutch once the clutches are fully engaged.  The present modulating pressure relief valve assembly provides a valve means that is effective to limit the maximum pressure in the system and change the pressure difference between the clutches upon full engagement thereof.  The valve means is located in a single bore thus reducing total valve size and manufacturing costs.
