Abstract: A hot surface detector for heavy ions following their separation on the basis of charge-to-mass ratio. Upon striking the hot surface, the heavy ions decompose and give up their lighter constituent and/or impurity atoms and molecules to the surface. Those constituent and/or impurity atoms and molecules with ionization potentials or electron affinities comparable to the work function of the hot surface become surface ionized and are emitted from the surface as a burst of either positive or negative ions which are then detected by conventional means, including detection at an electrode, by an electron multiplier or by a mass spectrometric detector for light ions. Where negative ions are to be detected, a magnetic field is applied to prevent electrons from the hot surface from reaching the detector.

Abstract: An implement preferably has elongated, stationary beams that extend horizontally transverse to the normal direction of travel. Staggered soil cultivating rotors are fastened to the beams at spaced apart locations and are ground driven to work closely adjacent strips of soil or a single broad path. Each rotor is freely rotatable about an upwardly extending shaft and has downwardly extending soil working members, such as tines, with lower active portions. Each active portion can have a lower outwardly directed part that, during rotation, describes a circle having a radius about equal to or less than the length of the active portion. The outwardly directed tine part increases ground contact and improves rotation. The rotors can be mounted in pairs; the rotors of each pair being angled from the vertical so that they rotate in opposite directions from one another.

Abstract: A cultivating implement has a row of soil working members that rotate about corresponding upwardly extending shafts that are driven by a common driving transmission. Each soil working member is independently connected to the implement frame by a linkage that permits pivoting to avoid an obstacle. Each member includes a horizontal arm with a stub shaft at each end of that arm and a tool that freely rotates about its respective stub shaft when the tool's tines contact the ground. The soil working members are mounted in a row that extends transverse to the direction of implement travel. A supporting roller is adjustably connected to the frame parallel to the row and can be used to regulate the working depths of the tines.

Abstract: A cultivator has a row of soil working members journalled in an elongated frame portion. The frame portion is supported on side-by-side elongated elements that extend generally parallel to the direction of travel.
