A system for supplying drywall mud in a viscous, flowable, semi-liquid form from a container for alternately filling at least two different types of drywall mud applicator devices is disclosed. The system includes a hand pump having a body partially disposed in a quantity of drywall mud in an open top container and a two way diverter valve having an inlet port attached to a discharge port on an upper end of the pump and the two outlet ports. One of the valve outlet ports is connected to a gooseneck tube for filling a bazooka type of drywall mud applicator and tape dispensing device. The other of the valve outlet ports is adapted for connection to a charging port of conventional corner box type drywall mud applicator device. A switch on a housing of the valve switches the valve inlet ports alternately into and out of communication with each of the valve outlet ports for alternately filling both types of applicator device without need for modifying the system. A two-way diverter valve for handling drywall mud when in a viscous, flowable, semi-liquid state is also disclosed.

The powered, moveable hitting tee of the instant invention is basically made up of a vertical tee, a reciprocating, horizontally disposed rod supporting the vertical tee, and a drive assembly or mechanism that is coupled to horizontally disposed rod to move the vertical tee towards the player. A moveable sled or carriage assembly movably supports the horizontally disposed rod. In one embodiment, a motor and pulley assembly is used for rotating a drive belt, which in turn moves the sled, the rod and the vertical tee. In another embodiment, a chain drive is used for moving the sled, the rod and the vertical tee. In another embodiment, a lead screw is used for moving the sled, the rod and the vertical tee. The particular structure that moves the vertical tee is not critical to the basic concept of the present invention. Rather, it will be apparent from this disclosure that various drive mechanisms can be made used to move the vertical tee towards the player. The vertical tee may include a rather rigid lower segment and a somewhat flexible upper segment made of memory-retentive material, which will bend but not be damaged when struck accidentally by a bat. The upper end of vertical tee upper segment may be flared to support a baseball or softball. In one embodiment, the tee support includes a coil spring as a shock absorber. A removable motor assembly and remote control devices may also be included.

The powered, movable hitting tee made up of a vertical tee, a reciprocating, horizontally-disposed rod supporting the vertical tee, a movable sled or carriage assembly within which the reciprocating rod is mounted, a drive belt or, in the alternative, a chain and sprocket assembly arranged parallel to and in operable contact with the rod, thus engaging the rod and driving the same, a motor for rotating the drive belt or chain, thus to move the sled, rod and vertical tee, and a box enclosure for all the components of the invention, save for a portion of the reciprocating rod and the vertical tee. The rod free-end and the base of the vertical tee are, in a first embodiment, only loosely, frictionally interfitted together so that, should the vertical tee be accidentally struck, then it will simply fall off of the rod, without damage to any of the parts of the invention. The vertical tee may include a rather rigid lower segment and a somewhat flexible upper segment made of memory-retentive material (e.g., rubber), which will bend but not be damaged when struck accidentally by a bat. The upper end of vertical tee upper segment may be flared to support a baseball or softball. In a second embodiment, the tee support includes a coil spring as a shock absorber for misaimed hitting. A removable motor assembly and remote control devices may also be included.

A portable circuit and method for performing a time study and analysis of bodily ionic characteristics as esophageal pH includes a transducer 11 for measuring pH and generating a proportional analog signal and an interface 12 for converting this signal into a representative digital signal including offset and gain controls 23,24 for permitting correction for transducer 11 calibration drift during the study period. A processor 14 receives and stores all digital signals for rapid transmission to a data analysis after the study period is ended. Esophageal pH values are measured and stored for a plurality of pre-study and post-study known conditions.
