Abstract: A lift for vehicles in service stations, repair centers and the like to lift such vehicles for the repair and servicing thereof. The vehicle lift includes a support for engaging the vehicle to be lifted, a power cylinder for lifting, supporting and lowering the support, and a pair of vertically extending columns for supporting and guiding the support during lifting, supporting and lowering of the vehicle. The columns include a first pair of channels inwardly facing towards one another and a second pair of channels integrally attached to the first pair and outwardly opening away from one another for balancing the rotating forces on the inwardly facing channels.

Abstract: Apparatus used for the directional surveying of deep wells, i.e., 20,000-25,000 feet (6,096 meters-7,620 meters), and which is specifically identified as a gyroscopic directional surveying instrument having a high pressure and a high temperature capability, e.g., 24,000 pounds per square inch (1,632.65 atmospheres) and 450.degree. F. (232.22.degree. C.). While in its fully assembled configuration, the apparatus may be described as being exceptionally long (or at times unwieldy), e.g., 12-16 feet long (3.66 meters-4.88 meters), it is quite remarkable that it does not exceed three inches (76.2 millimeters) in diameter. Therefore, it may readily be lowered into the small diameter steel casing normally defining the walls of these deep wells. In view of its cumbersomeness, it is significant to note that the apparatus may readily be broken-down into upper and lower sub-assemblies when being transported to or from the well site.

Abstract: A seed pickup mechanism for a vacuum wheel type seed planter including provision for arranging the seeds into a relatively thin stable seedbed which is suitably carried through a seed pickup chamber at a spaced distance below the vacuum wheel. The stable seedbed is converted into an unstable or fluidal state as it passes through the seed pickup chamber by an upwardly directed blast of air which is effective to expand the seedbed or slightly lift and separate the seeds thus the seeds are raised upwardly to facilitate engagement thereof with the vacuum wheel.
