Abstract: A wire crimping tool has two arms and an adjustable wire crimping device. The arms are pivotally connected to each other and each arm has a handle and a jaw. The adjustable wire crimping device is mounted on the jaws of the arms and has a duel crimping cavity and a threaded extension member. The duel crimping cavity is defined in a first one of the jaws and aligns with a second one of the jaws. The duel crimping cavity has an upper segment with a bottom and a lower segment. The lower segment is defined in the bottom of the upper segment and has a diameter smaller than that of the upper segment. The threaded extension member is adjustably mounted in the second jaw and has a crimping tip extending out of the second jaw and aligning with and extending into the duel crimping cavity.

Abstract: A liquid dispensing gun employing an interacting bore, piston and piston rod which gun is provided with adjustment means to determine the volume of liquid delivered by the gun. The adjustment means being a series of projections extending radially from the peripheral surface of the piston rod and arranged thereon to selectively engage a circular member located around the rod, which circular member is provided with a series of recesses extending longitudinally adjacent the rod into which the projections may enter.

Abstract: A liquid dispensing gun employing two interacting bores and pistons to maintain the liquid inlet and outlet of this gun stationary with respect to the gun during operation. The gun is attachable to a liquid reservoir and may employ either a nozzle to deliver a dosage of liquid into the throat of an animal or to inject a dosage via a needle.

Abstract: This invention detects, indicates and records road surface deviations in the normally-traveled vehicle tracks. Surface deviations detectable range from less than one inch in height to the largest height negotiable by the vehicle carrying the instrument. Final measurements are indicated from a mean surface, and with proper calibration numerical values may be established to give a meaningful quantitative description of the roughness of a given section of road.Description of the surface roughness is expressed by two linear dimensions: one is the height of the encountered deviation; the other is the distance between major deviations. For analysis of the data obtained, the first dimension, the height of the deviation, is used as recorded, and the second dimension is inverted to give frequency of deviation.Measurements are made by maintaining a predetermined reference plane with a gyroscope and sensing the carrying vehicle's roll and pitch.
