A street sweeper has a hopper rotatable about a single axis spaced rearwardly from the hopper between debris collecting and dumping positions. The hopper defines a chamber with an upwardly and rearwardly sloping rear wall and a top wall when in the debris collecting position. The single axis is elevated for a high dump configuration wherein a door in the chamber top wall may either be actuated bet...

Perhaloalkylvinylcyclopropanecarboxylates having the general formula are disclosed wherein one of Y and Z is a perhaloalkyl group having 1 to 4 carbon atoms and the other is hydrogen, halogen, lower alkyl, phenyl, phenylthio or benzyl, with the proviso that Y and Z may be combined to form a perhalocyclopentylidene group; R is halogen, hydroxy, lower alkoxy or -OR<1> in which R<1> represen...

The biological treatment of effluents is effected by several parallel chains of aerators, suspended from air hoses, if necessary with a carrier wire, across the basin. The aerators are located near the bottom of the digested sludge basin and are oscillated when supplied with compressed air. Only a part of the chains receive the full air supply at a time; the others are more or less cut off so that...
