Abstract: ABSTRACT A scale testing vehicle and method for use on platform scales, having at least one scale section, is disclosed.  The scale testing vehicle includes a chassis which mounts front and rear axle assemblies.  A weight bed is mounted on the chassis together with a crane.  The weight bed receives a plurality of uniform weight units which may be removed and replaced by the crane from their location on the bed.  A pair of lifting cylinders are mounted immediately adjacent and forward the wheels of the rear axle assembly. After the vehicle is driven onto a scale section, the cylinder lifting legs are extended wherein the front of the vehicle is elevated and the entire static load of the vehicle and weight units is applied to the lifting legs and the rear axle assembly, both of which are confined within the periphery of the individual scale section.  The known vehicle load is then compared with the load indicated by the scale.  If required, individual areas with-in the periphery of the scale section are tested by removing the vehicle from the scale section and placing uniform weight units at various locations on the scale section.  A comparison is then made of the known load of the uniform weight units and the load indi-cated by the scale at each of the various areas tested.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved electrode assembly for a high-in-tensity ionizer array utilized as the first stage in a two-stage electrostatic precipitator.  Each ionizer unit employs a pair of co-axial electrodes to create a high-intensity electric field across the path of a particulate-laden gas stream.  As the gas passes through the field it is intensely ionized and the particulate becomes highly charged.  The ionizer anode comprises a venturi diffuser through which the gas stream flows immediately prior to entry into a preci-pitator stage which removes the charged particles.  The ionizer cathode is a disk co-axially mounted within the venturi throat and having an arcuate periphery.  A high voltage power supply connected between the anode and cathode establishes a high-intensity corona discharge in the annular region formed between the periphery of the cathode disk and the surrounding cylindrical anode surface.  The section of the venturi wall in the area of the cathode disk is formed with a series of axially spaced conical vanes.  The spaces between adjacent vanes define annular injection nozzles which are oriented to direct clean gas supplied under pressure from an external source into a venturi charging region and along the interior anode surface in a laminar flow in the direction of the primary gas stream.  The laminar film of clean gas sweeping along the venturi wall envelopes the primary gas stream and provides an effective barrier to particle deposition on the anode surface.

Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus for cutting web material transversely to form sections has an arrangement for advancing the material a section at a time across a linear cutting edge.  A linear guide parallel with the edge carries a circular blade which overlaps the linear cutting edge said blade being reciprocably driven along a linear guide.  Each forward and each reverse, cutting-stroke of the circular blade cuts off the then advanced section.  The advancing arrangement is timed to operate between the ends of the forward strokes and the beginnings of the reverse strokes of the circular blade and vice versa.  A preliminary advancing arrangement may be provided for advancing a measured amount of web material to form slack which is taken-up by advancement of the material across the linear cutting edge.  Structural honeycomb material may be produced by using-two layers of material laminated together by bands of adhesive, and bearing other bands which are exposed, and arranging pressing devices which follow the circular blade and press the sections into a receiving throat.

Abstract: ABSTRACT     A beverage dispensing system includes a non-refrigerated pressurized source of carbonated beverage connected through a refrigeration line to a four-way valve which directs the beverage to one side or the other of a metering device to fill it, while being also connected to said other or said one side respect-ively to drain the other side of the metering device and to direct the beverage through a restrictor to a dispensing valve. The structure is miniaturized and thus there are relatively high velocity flows of beverage which would tend to cause foaming.          Foaming is eliminated by the restrictor which maintains the pressure at the four-way valve and upstream therefrom at a pressure level which is in excess of the partial pressure of the carbondioxide gas in the beverage, thus eliminating foaming.
