Abstract: A sampling apparatus is characterized by a housing having a bore extending therethrough, which is supported with one end of the bore communicating with the interior of a liquid containing vessel and with an opposite end of the bore being outside of the vessel. A plunger or cylinder rod is positioned in the bore and has an annular recess intermediate its ends of a length longitudinally of the plunger which is less than the length of the bore. A pneumatic cylinder is connected with the plunger at the opposite end of the bore for reciprocating the plunger in the bore to project the recess into the vessel to receive a sample of liquid therein, and to then move the recess from the vessel and to an intermediate point in the bore whereat a housing outlet port receives the sample. First and second seals on the plunger to opposite sides of the recess maintain a liquid seal between the one end of the bore and the outlet port during reciprocation of the plunger, and a third seal is on the plunger toward the opposite end of the bore. The third seal absolutely blocks passage of any sampled liquid to the pneumatic cylinder, and wipes the bore clean between the opposite end thereof and the outlet port with each reciprocation of the plunger.

Abstract: A sampler for obtaining small samples of material from a flow of bulk material as it is transported past a sampling station, is characterized by a sample collecting scoop which is rotated in an arcuate path through the material about an axis inclined at an angle with respect to the major plane of the material. The scoop moves through the material generally in the direction of material flow and at a speed slightly greater than that of the flow, and by virtue of its inclined axis of rotation has components of motion therein both vertically and transversely of the material. In consequence, even if the material is segregated the sample obtained by the scoop is a true representation of the material. After leaving the material, the scoop is then rotated to a sample collection point above and transversely to the side of the material, whereat the sample is deposited in a container. A number of such samples obtained from different parts of the material flow may be combined to build a representative composite sample, which is then analyzed to determine the overall composition of the bulk of material.

Abstract: A sampler for communicating with the interior of a vessel containing a liquid extracts a liquid sample of predetermined volume from the vessel and conveys the same to a point of collection. The sampler includes a body having a bore, the forward end of which is in communication with the interior of the vessel, along with front and rear plungers reciprocable within the bore under positive independent control. The plungers are movable away from and toward each other to establish and collapse a sample chamber therebetween. To obtain a liquid sample, the plungers are removed forwardly to project the front plunger out of the bore and place the sample chamber into communication with the vessel interior, whereupon the sample chamber is established for being filled with liquid. The plungers are then moved rearwardly into the bore with the liquid filled sample chamber therebetween, until the chamber is exposed to a port in the bore, at which point it is collapsed to force the liquid out of the chamber and through the port under positive pressure. The sampler may also be used as a metering pump, with liquid being introduced into the sample chamber through the port and then carried through the bore by the plungers to and into the vessel.

Abstract: A sampler for communicating with the interior of a vessel containing a slurry under pressure extracts a sample of the slurry from the vessel and conveys the same to a point of collection. The sampler includes a conduit having an inlet for communication with the interior of the vessel and an outlet to the exterior of the vessel, and a valve for selectively establishing and interrupting communication between the conduit inlet and the interior of the vessel. When communication is established, a sample of slurry flows into the inlet, through the conduit and to the outlet for collection, and when communication is interrupted a source of flushing liquid is coupled with the inlet to flush the conduit clean of residual sampled slurry. By virtue of introduction of flushing liquid through the conduit when slurry is not being sampled, residual slurry is prevented from settling out and/or hardening in the conduit and clogging the sampler.

Abstract: A shield assembly to be positioned between a work area of a machine tool and an operator station is characterized by a unitary, generally U-shaped transparent sheet of a durable polymer having a planar front center portion and side legs diverging therefrom. One of the side legs is equipped with a handle and is secured to one end of a universal support arm, the other end of which is mountable to the machine remote from the work area.The handle and universal arm enable the shield to be quickly and positively moved between positions adjacent and remote from the work area. When adjacent, the center portion of the shield extends across the front of the work area and the side legs extend rearwardly across opposite sides thereof to form an effective barrier to the passage therepast of chips, broken tools, coolant, etc., ejected from the work area.
