摘要： Apparatus for effecting and controlling the firing of energy sources, particularly is seismic work, includes means for automatically correcting the delays between the desired and actual firing times which may be different for different sources. These means comprise a number of programmable counters for initiating the firing of different sources, a reference time counter to indicate the desired firing time or times and comparator means responsive to differences between actual and desired firing times to cause the programmable counters to bring the actual firing times towards the desired firing times.

摘要： An attachment for a bench grinder having at least one grinding surface, a tool rest fastener and a tool rest is described. The attachment includes a tool-receiving plate having a bottom surface and a top surface. The bottom surface is configured to matingly engage the tool rest surface. The top surface includes one of a flat surface and a surface having an angled V-shaped groove that is shaped and configured to receive a drill bit or and hold it at a fixed elevation and angle relative to the grinding surface. A slotted flange is normally attached to the tool-receiving plate, is configured to engage the slot with the tool rest fastener while the tool-receiving plate rests on the tool rest surface, and to abut the flange against the attachment surface to hold the attachment immobile during use.

摘要： An apparatus for splitting solid and hollow masonry materials is provided. The apparatus includes changeable support tables and upper splitting blades to accommodate various types of masonry materials. A hydraulic ram is operated via a foot pedal to increase the pressure in the ram to raise a lower cutting blade and spring-loaded support table to exert upward and downward pressure on the material, coming it to clearly split. The upper blade is height-adjustable and the support table can be fixed in a lowered position to facilitate the splitting process by eliminating overly repetitive operation of the hydraulic ram.

摘要： A sonic generator sends a collimated acoustical wave into the section of earth under test and resonance conditions are established depending upon the nature and depth of discontinuities in the path of the acoustical wave. These resonance conditions are monitored by observing and recording electrical relationship in the power supply section of the sonic generator.

摘要： A method for finding the position of a drill bit working at the bottom of a borehole comprising sending ultrasonic energy down the drill stem, recording the energy radiated from the drill bit through the earth to an array of geophones around the wellhead on the surface, and calculating the distance from the drill bit to each geophone. The drilling mud surrounding the drill stem absorbs the slight amount of ultrasonic energy that escapes laterally so that substantially all of the effective signal is generated at the bottom of the hole where the drill bit is working.
