Abstract: A method and apparatus for measuring multiple parameters of drilling fluid using electric field perturbation, permittivity curves, time domain analysis and frequency domain analysis to identify constituents of drilling fluid and ratios of the drilling fluid constituents on a real time basis and to measure volumes and densities of the constituents on a real time basis.

Abstract: A clamping member (16) is substantially in the form of a cylinder with a narrow strip removed. The clamping member (16) is lined with a resilient layer (136). A heating layer (138) is positioned between the clamping member (16) and the resilient layer (136). A cup (22) surrounded by a heat transfer (142) is positioned in the clamping member (16) when the clamping member (16) is in an open position. Then, the end portions (42, 44) of the clamping member (16) are moved together so that they will in turn move the clamping member (16) and its liner (136) into snug engagement with the outer surface of the cup (22). Then electrical energy is applied to the heating element layer (138) for causing a transfer of printing and/or design indicia from the transfer (142) to the outer surface of the cup (22). Swinging movement of a handle (18) between first and second positions operates a mechanism that opens and closes the clamping member (16).

Abstract: A handle (22) is moved between a first position (FIG. 1) and a second position (FIG. 2). When the handle (22) is in its first position a mechanism between the handle (22) and an upper platen (20) raises the upper platen into a raised position. In this position it is above a work piece mounting board (26) which in turn is spaced above a lower platen (18). Movement of the handle from its first position (FIG. 1) into its second position (FIG. 2) causes the mechanism to move the upper platen (20) downwardly against a work piece on the work piece supporting board (26). As the upper platen (20) moves downwardly, it moves the work piece and the work piece supporting board (26) downwardly against the lower platen (18). An adjustment mechanism (122, 86, 92) provides for a way of compensating for different thicknesses in the work piece that is on the work piece supporting board (26). A four-bar linkage (50, 52, 54, 56) mounts the work piece supporting board (26) for vertical up and down movement.

Abstract: A carrier sleeve (32) surrounds a post (14) that extends upwardly from a base (12). A lower platen (18) is mounted on the base (12). A horizontal support arm (16) is mounted on the upper portion of the post (14) An upper platens (20) is mounted on the support arm (16) above the lower platen (18). A work piece support (26) is mounted on the post (14) between the upper and lower platens (18, 20). The work piece support (26) is connected to the carrier sleeve (32) and is movable up and down along the post (14). A spring (36) is positioned below the carrier sleeve (32) between the carrier sleeve (32) and a portion of the base (12). In a relaxed condition, the spring (36) holds the work piece support (26) in a position that is vertically between the upper and lower platens (18, 20) when the upper platen (20 is raised. The upper platen (20) is movable downwardly into contact with the work piece support (26).
