Abstract: Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

Abstract: An example robot includes a first actuator and a second actuator connecting a first portion of a first member of the robot to a second member of the robot. Extension of the first actuator accompanied by retraction of the second actuator causes the first member to roll in a first roll direction. Retraction of the first actuator accompanied by extension of the second actuator causes the first member to roll in a second roll direction. A third actuator connects a second portion of the first member to the second member. Extension of the third actuator accompanied by retraction of both the first and second actuators causes the first member to pitch in a first pitch direction. Retraction of the third actuator accompanied by extension of both the first and second actuators causes the first member to pitch in a second pitch direction.

Abstract: Spectrum eyeglasses to provide a tranquilizing field of vision to the user are disclosed. The eyeglasses of the present invention comprise a frame mounted in front of the eyes of the user, an opaque wall supported by the frame positioned to prevent the entry of ambient light to the eye, a light source, a color wheel for selectively coloring light emitted from the light source, an opening formed in the opaque wall to expose the user's eye to a selectively varied field of color that is tranquilizing and sleep inducing.

Abstract: An improved instrument for preparing quality control solutions of liquid and gas for use in calibrating blood gas analyzers includes a gas inlet providing gas to a humidifier, a diffusion tube, flexible tubing connecting the gas from the humidifier to the diffusion tube and a temperature controlled environment for the diffusion tube. These standard components are arranged in a unique combination permitting the tubing connecting the outlet of the humidifier to the diffusion tube and the diffusion tube itself to both be replaced or individually replaced without disturbing the other components of the instrument. For this purpose, a metal heat block is used as the temperature controlled environment and is provided with an open top for receiving the diffusion tube. The humidifier and connecting tubing are exterior of the heat block so that the referred to replacement of the tubing can readily be carried out.

Abstract: This invention pertains to a process for the manufacture of metal soap granulates or mixtures thereof by means of reacting an aqueous solution or suspension of a metal oxide, metal hydroxide or metal carbonate, including basic metal carbonates, or mixtures thereof with a water insoluble fatty acid which may be aliphatic, saturated or unsaturated, straight chained or branched and which may either be natural or synthetic fatty acids, having a chain length of C.sub.8 -C.sub.32 and a melting point of above 0.degree. C. and below 100.degree. C.; such fatty acids may be used alone or in mixtures with the reaction taking place in the absence of catalysts and wetting agents.

Abstract: A computer system executes instructions for an I/O device not attached to the system. A quasi I/O attachment device is responsive to the commands for the unattached I/O device and generates an interrupt condition. The interrupt condition causes the command instructions for the unattached I/O device to be translated to command instructions for an I/O device connected to the computer system. The I/O device attached to the system performs the designated operation and generates associated I/O device status data. This associated I/O device status data is translated into I/O device status data for the unattached I/O device and thus permits a program for operating an unattached I/O device to operate instead an I/O device attached to the system which otherwise could not be operated by that program. A second embodiment performs the emulation of the unattached I/O device remotely of the central processing unit in the computer system.
