Abstract: A system for transporting parallel digital data in which the parallel digital data is converted to serial digital data, transported as serial digital data, and then reconverted back to parallel digital data. Each parallel digital word to be transported is stepped into a parallel to series shift register which has associated with it a separate digital code to identify the particular digital word. The data in the shift registers is serially stepped out, one shift register at a time, and then transported as serial data to a plurality of series to parallel shift registers. Each series to parallel shift register has associated with it a particular digital code associated with a particular digital word. Each shift register receives the serially transported data, and if the digital code of the shift register matches the digital code of the received word, the data in that particular shift register is stepped out as a parallel digital word.

Abstract: A dispensing nozzle assembly having a system for receiving the vapors displaced from a motor vehicle gasoline tank when it is being filled, an interlock system for preventing the dispensing of gasoline until the vapor receiving bellows is in contact with the fillpipe of the vehicle gasoline tank, and an attitude control valve system to prevent vapors from the underground storage tanks from being displaced back into the atmosphere through the vapor receiving system. The interlock system includes a valve connected in the vent line running from the end of the discharge spout to the automatic shut-off system in the nozzle housing, said valve being interconnected with the vapor receiving system so that it is closed when the vapor receiving system is not in contact with a fillpipe, causing the automatic shut-off system to prevent dispensing of gasoline.

The piston element includes expandable side walls adapted for frictional engagement with the side walls of the tubular housing. Control means are provided for controlling the expansion of the piston walls, the resultant friction produced therealong and the preferred rate of movement of the core into the tubular housing under the force of gravity. The construction of the tubular housing permits the core received therein to be retained in its original extracted condition while facilitating the handling, subsequent examination and analysis thereof.

Abstract: A spectroscopic system for measuring the discontinuous far infrared radiation emitted by a semi-transparent material, and including compensation for background, graybody, emitted radiation.In a first embodiment, a system is disclosed for measuring the far infrared radiation emitted by a lubricant in contact with a steel ball under high pressure. The lubricant is coated on a small diamond disc mounted as a window in a steel plate. The steel ball is rotated over the window to form a sliding elastohydrodynamic (EHD) contact region with the lubricant. Some of the radiant energy generated in the contact region, both in the fluid and at its boundaries, passes through the window into an infrared interferometer, which generates an emission spectrum. The spectrum is separated, by a balancing technique utilizing a rotating chopper blade, into contributions from the fluid and contributions from the steel ball.

Abstract: An improved valve for separating and sealing adjacent pneumatic tube sections of a pneumatic tube delivery system. The valve includes a pair of flap seals positioned on opposite sides of the travel path of a carrier through the valve. Each flap seal is spring biased closed, and has a shock absorbing element positioned behind it such that when the flap seal is kicked open by a carrier, the spring bias and the shock absorber will absorb the momentum of the kicked open flap seal. An air inlet section in the valve is designed to minimize the intake of rain and snow and further to minimize the coasting distance experienced by a carrier traveling through the valve.

Abstract: An ice chipper comprising a pair of cylindrical drums each mounted for counter-rotation about parallel, generally vertical axes. Each drum includes an outwardly rounded, disk shaped bottom surface and an auger flight spiraled helically about the outer cylindrical surface thereof. The auger flights each include a plurality of spaced, outwardly extending teeth to chip the ice abutting the front of the system. The chipper is mounted to the front of a tractor and each drum includes a hydraulic motor which is operated by a hydraulic pump also carried by the tractor. Rotation of the drums causes the auger teeth to chip the ice and tends to pull the drums forwardly while the auger flights carry the ice particles up and out away from the cleared area. Tilting the system forwardly and rearwardly upon the rounded drum bottom surfaces varies the depth of cutting in the vertical direction.
