Abstract: A wave solder machine is provided which includes an endless moving mesh belt that is made of a nonsolderable material such as titanium wire. The belt is supported so as to be totally immersed in the solder wave as it passes the latter. This causes the undersides of stuffed printed circuit boards on the belt to be brought into contact with the molten solder. The belt wires preferably have a plurality of projections thereon to support the circuit boards above the major portion of the belt. In another machine, the circuit boards are moved along a plurality of parallel wires that pass through the solder wave. Alternatively, the wires themselves may be moving for carrying circuit boards across the solder wave.

Abstract: A contact element is produced by sonically welding one or more contact pieces onto a carrier, an intermediate layer, for example of aluminium foil, being interposed between the contact piece and the carrier prior to such welding in order to assist in the welding of the contact pieces made of material which would otherwise be difficult to weld. Typical frequencies of sonic welding lie in the range between 20 kHz and 50 Hz.

Abstract: The cone cutter of each segment of a multi-segment rock bit is assembled onto its segment. A pin end of the segment is supported by an index pin and axially constrained in the direction away from the cone cutter. The cone cutter is clamped against and dimensionally indexed on a cone saddle having a circular surface of a diameter corresponding to the gage diameter of the completed rock bit. The cone is loaded in a direction axially of the segment in a manner to simulate the loading of the hole bottom that is to be drilled by the rock bit. The segment away from the cone is also loaded radially of the axis of the segment to take up tolerances along the axis of rotation of the cone cutter. The constraint of the cone and loading of the segment simulate the hole wall force on the cone experienced at the gage row and takes up tolerances radially of the axis of rotation of the cone along a line to the gage row in contact with formation material. A bridge prevents rotation of the segment about its lengthwise axis.

The cutter blade is elongated and generally flat, being tapered in the "width" direction for applying the taper to the hole, and being tapered in the "thickness" direction so that the cutting edge along the length of the blade will lead the cutting edges proximate the point and thereby minimize point drift. All cutting edges of the blade are provided with a substantial negative rake for chip control, and the chips are blown out of the hole by jet streams of cutting fluid directed along the longitudinal cutting edges of the blade.

Abstract: A verticle spindle carrying cutting blades at its bottom end and a knob at its top is rotatably and slidably journaled in a neck of a housing positionable around vegetable or fruit to be sectioned. Rigid with the neck and coaxially surrounding the spindle are oppositely oriented upper and lower sets of sawteeth whose sloping flanks coact with respective groups of camming formations rigid with the spindle and disposed at the upper and lower ends thereof. These camming formations engage the associated sawteeth during the final phases of a cutting stroke and a return stroke of the spindle with a relative offset of a fraction of a pitch to impart to the spindle, knob and blades a stepped rotary unidirectional motion. The upper sawtooth flanks are more steeply inclined than the lower ones whereby the angle of rotation during a manual downstroke is less than that occurring during an upstroke brought about by the pressure of a restoring spring inserted between the knob and the housing.
