Abstract: A high chair catch tray attachment comprising a generally rectangular tray is selectively engageable with a child's high chair and supported thereby to provide a catch surface to catch and support objects, food and utensils dropped by the child occupying the high chair. The catch tray is adjustably postionable and supported by the high chair legs so that the catch tray surface may be maintained at a height that supports objects and food falling on and supported by the catch tray out of reach of the child occupying the high chair.

Abstract: A wire transfer mechanism for transporting a length of wire conductor from a feed location to a terminating location and then depositing the length of wire at a collection location is disclosed. The mechanism includes at least one transfer arm mounted for pivotable motion back and forth; a releasable gripper mechanism positioned at the end of each transfer arm for gripping a length of wire to inhibit relative motion in a direction normal to the axis of the wire, and an actuator mechanism for releasing the gripper mechanism while the transfer arms move from a wire terminating position to a wire pickup position at a finite velocity and for decelerating the transfer arms, so that the momentum of a wire gripped in the gripper mechanism will carry it away from the transfer arms in a direction normal to the axis of the wire.

Abstract: A process for extracting raw and crude avocado oil from avocados with optimum yield and minimal chemical change in the oil. Raw avocado oil is extracted from ripe fruit following maceration, heating, addition of herbaceous silicious material, and pressure extraction. Crude avocado oil can be extracted from the remaining cake by refluxing with suitable solvents. The oil can further be refined by treatment in a diatomaceous earth filter.

Abstract: A system for correlating condition-indicative signals fed sequentially from a series of sensors, such as thermocouples installed in ports on the surface of a rotating kiln at various longitudinal and angular coordinates along the total length of the kiln, with the signals printout on a multipoint recorder mounted remotely from the kiln is disclosed wherein two photoelectric devices are disposed at fixed points adjacent the kiln for sensing the passage of a series of sensor-location indicator tabs mounted on and rotating with the kiln.

Abstract: A system for monitoring the internal conditions in a rotary kiln is disclosed wherein a series of sensors, such as thermocouples, are installed in ports at various longitudinal and angular coordinates along the total length of the kiln for providing temperature signal samples in the form of sequenced millivolt signals, and a single thermocouple is provided which is insertable in a second series of ports along the kiln to permit immediate localized temperature sensing. The sequenced millivolt signals and the single thermocouple millivolt signals are both fed to respective millivolt-to-milliamp converters mounted on a heat shield on the kiln surface, which shield also mounts two sets of continuous slip rings encircling the kiln. The respective milliamp signals are communicated from the converters to the respective slip ring sets from which they are picked off by suitable stationary contact means disposed adjacent the kiln and conducted to appropriate recorders in a control room.
