An incinerator system which minimizes the emission of pollutants into the atmosphere is disclosed. The system includes an afterburner which receives the exhaust material of an incinerator, and which is preferably constructed of rhyolite material having only minimal traces of iron oxides. The afterburner includes a passageway having a constricted venturi section which expands and accelerates the exhaust materials to maximize the combustion thereof at a relatively moderate temperature. The inciner...

An improved irrigation system of the type including a plurality of distribution conduits equipped with uniformly spaced spray heads for emitting temperature-controlling bodies of mist, and a continuous-flow heat exchanger for supplying heated water to the spray heads. The heat exchanger includes a fire box of a tubular configuration, a tubular shell defining about the fire box a cylindrical water jacket for conducting a stream of water along a tortuous path extended about the external surface of...

Bypass around a filter in a conduit is prevented by providing first and second closures between the conduit and the high pressure and low pressure sides, respectively, of the filter, and creating a pressure in the conduit between the two closures that is lower than the pressure on the low pressure side of the filter.

A transportation system includes two power sources that extend along opposite sides of a right of way for an electrically powered vehicle. Each power source includes an elongated open side housing of electrically insulating material that defines a channel having opposed inner surfaces disposed at an angle to one another and tapering inwardly. A power conductor is disposed in each inner surface and a third power conductor is located at the innermost end of the channel substantially midway between...

A filtering system for cooking vessels includes first and second stage filters and a pump therebetween. Hot cooking oil is continuously passed through a first stage filter wherein larger particles are removed, after which the oil is passed through a second stage filter wherein small particles are removed. The media in the second stage filter comprises thin, fibrous paper material presenting interlocking fibers between layers in a multilayer roll, with the hot cooking oil being pumped axially thr...

A partition system including apparatus for joining movable wall partitions or panels comprising an elongated, cylindrical connector received in corresponding apertures formed in the edges of at least two partitions. The connector includes threaded apertures extending transversely thereof and spaced apart a predetermined distance such that one threaded aperture is in each partition. Threaded pins or bolts having tapered heads are received in each of said threaded aperture through slightly oversiz...

Method and apparatus for selectively interrogating decoding devices which are located at remote stations. In one embodiment, a number of transponders which make up a final group within a larger group of transponders, all attached to a common line running from a central station, are selected and simultaneously caused to retransmit modified interrogation signals in accordance with certain informational characteristics and the identity of each transponder retransmitting. The final group of transpon...

A conveyor system adapted for use at drive-in windows and the like which incorporates a flat container having a folding lid which can be opened from either end and adapted to receive therein bank deposits and the like, a carrier system extending between two designated points, an endless loop which moves the flat container, and a pair of rails utilizing tubular stock with centering rollers engaging each of the rails. An alternative embodiment is disclosed which includes an upstanding container wh...

A card registry system comprising a container having a rhomboid outer shape and upwardly diverging side walls, a plurality of dividers pivotally arranged within the container for pivoting at an angle to the side walls, and support means extending across the container between the side walls for supporting the dividers. The dividers have end rails at the opposite ends with offset sections on opposite sides of the divideraligned with the offset sections of the next adjacent divider.

A vehicle drive system in which acceleration and deceleration of vehicles between the high speed sections and low speed sections is provided by variable speed cables gripped by the vehicles and driven at gradually changing speeds. The vehicles may be driven in the high speed section by a single high speed cable. A clamping mechanism on each of the vehicles has grips for selectively gripping the high speed cable in the high speed section and the appropriate variable speed cable in the acceleratio...
