Abstract: A material flow inducing device for use in a material grinding apparatus. The grinding apparatus includes a grinding mechanism for grinding material, a motor for driving the grinding mechanism, and a hopper portion for holding a quantity of material for grinding in the grinding mechanism during a grinding operation. The flow inducing device includes a stirring member having extending arms which curve in a direction complimentary to a direction of rotation of the stirring member. The arms of the stirring member are compressibly flexible. Also included in the flow-inducing portion is an auger positioned between the stirring member and the grinding mechanism. Both the stirring member and the auger are operatively associated with the motor such that the stirring and auger rotate during a grinding operation. A material metering portion is positioned in the grinding apparatus in a surrounding relation to the auger member and has multiple downwardly spiraling inwardly sloping troughs formed in a top surface.

Abstract: A vibration isolation and EMI/RFI shielded enclosure for a horn antenna comprises an elongate hollow housing of sufficient dimensions to receive the horn antenna therewithin. Respective front and rear vibration isolation mounting assemblies have inner mounting portions coupled with the horn antenna and outer mounting portions coupled with the housing and resilient vibration damping members coupled intermediate the inner and outer mounting portions. Preferably, an EMI/RFI shielded enclosure is also provided for enclosing electrical circuits associated with the horn antenna.

Abstract: A non-rotating axially-paying-out ski-rope bobbin comprises a molded-plastic body shaped to define a vertical-axis circumferentially-open annular space for receiving a ski-rope manually wound therein. A plurality of suction cups are fixed to the under face of the body for quickly and easily detachably fastening the bobbin to the rear deck of a motor boat. A bail-shaped element is swingable from a storage position in a plane close to and parallel to the plane of the suction cups, to an upright use position in which its crest overlies the bobbin adjacent its axis. A ski-rope guide is fixed to, or formed in, the crest of the bail-shaped element to change the vertical-conical over-edge rope-paying-out to a horizontal rearward paying-out. The guide is vertically open so that the rope, whose boat end is to be tied to the boat transom, will pull free from the bobbin when fully unwound therefrom.

Abstract: An analysis instrument for measuring selected constituents present in a sample of a material such as a bulk commodity includes a test cell to receive the sample. The test cell comprises a capacitor whose electrical properties are modified in accordance with the dielectric constant of the sample, which dielectric constant is a function of the contents of the sample. A hopper is mounted above the test cell for holding a quantity of the commodity to be tested and doors forming a bottom of the hopper are selectively openable to introduce the material from the hopper into the test cell. A strike off mechanism is provided for striking off the sample level with the top of the test cell to assure a constant volume of sample material therein. Weight and temperature sensors are provided for measuring the weight and temperature of the sample. An unloading mechanism is provided for rotating the test cell to remove the sample therefrom upon completion of the measurements.
