Abstract: A diversity receiving apparatus includes first and second antennas and circuitry for selecting one antenna or the other. Control circuitry analyzes signal strength received from the selected antenna and determines when the antennas should be switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched.

Abstract: A tamper-indicating plastic closure includes a plastic closure cap having a top wall portion, and a depending cylindrical skirt portion, and an annular pilfer band depending from the skirt portion.

Air drawn through the spirometer by a patient rotates the turbine and the signal device indicates the volume of air that has passed through the spirometer.

Abstract: An improved method and apparatus for treating liquor containing biodegradable wastes wherein the liquor is first delivered to a quiescent primary settling zone and then to an aeration zone. The aerated liquor is delivered downwardly through a column of submerged fixed media having a high surface area to volume ratio so that aerobic microorganisms can grow on their surface. The liquor is recirculated through the aeration zone and fixed media, and is withdrawn from the unit after treatment. A portion of the aerated liquor from the top of the fixed media is recycled back into the primary settling zone to denitrify the nitrate rich aerated liquor by deoxygenating the dissolved nitrates and to equalize the BOD load in the secondary aerobic treatment zone.

Abstract: A rotary accumulator for folded beams of corrugated paperboard with adhesive applied thereto, such as pallet stringers or decking members, comprises a conveyor for feeding the beams longitudinally with spaces therebetween, a generally circular array of beam holders mounted to a rotary framework for receiving each beam in one holder, for holding such beam in a desired configuration for a finite time to allow adhesive applied thereto to cure, and for releasing such beam thereafter, a mechanism for indexing the holders in a generally circular path, and a longitudinal member for removing each beam from the beam holder holding such beam when such beam engages such members as the holders are being indexed. The mechanism is powered by a pneumatically powered piston-cylinder mechanism, which drives an escapement mechanism, or by an electric motor. Certain sensing and detecting devices are provided for controlling the mechanism.

Abstract: An automated conveyorized oven includes a radiant heater assembly including a plurality of gas-fired radiant heaters positioned beneath the oven conveyor. Each heater assembly includes radiant heating elements in the form of perforate metallic plates, at the outer surface of which combustion takes place for elevating the temperature of the plates for generating radiant heat. Consistent and reliable operation is promoted by the provision of a control arrangement which acts to preclude flashback combustion upstream of the surface of the metallic heating elements, with the controls being operable to permit sufficient time for the heating elements to cool, after interruption of the gas supply thereto, before gas is resupplied to the heater units.
