Abstract: DISTRIBUTION TOWER FOR PARTICULATE MATERIAL     ABSTRACT OF THE DISCLOSURE         An improved distribution tower for weighing and mixing particulate material such as chemical fertilizer has a plurality of storage containers therein for separate storage of various particulate materials and utilizes a combined weighing and mix-ing bin which is positioned below the storage containers to receive material therefrom, the bin being provided with an upright central auger for mixing and blending the material before dis-charging the material through a discharge duct at the base of the bin.  The bin is also provided with a weight measuring scale to weigh quantities of material added thereto from the storage con-tainers so as to permit predetermined fertilizer compositions to be formulated.  In one embodiment the auger apparatus has radial paddles to better mix the material.  A second embodiment utilizes a combined weighing and mixing bin wherein a funnel-like con-figuration of spaced-apart baffle plates is carried by the bin and intercepts and redistributes material discharged by the auger.          An outwardly flared distribution shield is positioned below the baffle plates to intercept material from the plates and further distribute the material.  The auger may have outwardly extending tabs adjacent its lower end for mixing material and may also have a radially extending arm at its upper end to discharge material outwardly toward the bin sidewalls.

Abstract: POULTRY WATERING DEVICE AND SUSPENSION THEREFOR            ABSTRACT OF THE DISCLOSURE         A boom is pivotally suspended from the ceiling in a barn and carries the waterer on one end thereof at the de-sired height from the floor.  A snubber is attached to the upper end of the boom which engages the ceiling and controls the distance of the waterer from the floor under certain con-ditions and also prevents inadvertent rotation of the water-er.  The water supply hose extends from the ceiling to the waterer.  The boom is manually moved in a circle or part cir-cle and the radius in one embodiment is adjustable within limits.  In another embodiment, a spring loaded pivot is used making rotation relatively easy when the waterer is lifted to free the snubber from the ceiling.  The ability to move or rotate the waterer controls the manure build-up around the waterer thereby spreading the manure over a larger area.  Be-ing able to move waterer readily and easily enables  barn equipment to move through the barn as desired.

The flange of the cage contacts a pressure plate connected with tappets disposed uniformly on the periphery.  The other ends of the tappets contact the crown cam fitted non-rotatably in relation to the axle housing.  The disc is connected with the tappets and between the disc and the housing tension springs are install-ed.

Abstract: Abstract of the Disclosure A portable, handheld data entry device is disclosed which includes a solid state memory for providing bulk storage of data entered through a keyboard, scanning wand, or other data entry means.  A microprocessor controls the various operations performed by the unit, including storage of data in memory and memory management.  During operation, the memory is defined to include a number of independent data storage sections or partitions.  Each partition includes a data block containing related data which has keen entered into the partition.  All re-maining free memory space is located in a single partition, adjacent to the data block of that partition.  Data may thus be added to that partition by entry of the data into the free memory space adjacent to the data block.  When data is to be entered into a different partition, the data blocks are relocated in memory so that the free memory space is instead within that different partition, adja-cent to its data block.  The size of each partition is therefore not fixed, but varies with the data entered.  me data entry device also incorporates methods of sending selected partition in any arbitrary order to an external device, and of editing the partition data block by inserting or deleting variable-length data records.
