Abstract: A mandrel arrangement for mounting a pipe machining tool for rotation relative to at least one end of a pipe elbow or other bend to be machined. A mandrel frame is provided with first and second flange portions having outer surfaces located within planes which intersect to form a predetermined angle approximately equal to the angle of the pipe bend. The frame is adapted to be positioned within the pipe bend with an outer surface of the first flange portion adjacent a first end of the pipe bend and an outer surface of the second flange portion adjacent a second end of the pipe bend. A locking means connected to the mandrel frame is adjustable between a first radially retracted condition in which the frame is free to move relative to the pipe, and a second radially extended condition in which the frame exerts an outward force against the interior of the pipe to frictionally retain the frame from movement relative thereto.

Abstract: Skin ridge pattern recording apparatus for obtaining and recording skin ridge patterns. A cylindrical transparent element is provided with a central cylindrical bore which, reflects internally. The finger is placed in the bore for producing the skin ridge patterns. The cylindrical element is mounted on a vertical column or post upstanding from a platform which carries a light source projecting a beam of light to the cylindrical element. The light source and a sensitive camera film are carried on a platform which is rotatable with respect to the cylindrical element in which the finger is inserted. The film plane of the camera remains in a fixed relationship with respect to the reflected light from the light source, the angle of incidence being determined by the position of the light source relative to the cylindrical element. The platform is motor driven so that the light source and the film plane of the camera rotate around the cylindrical element to produce the recordation of the skin ridge pattern.

Abstract: A drum towel drier for vehicles, in which towel holders are pivotally mounted around the periphery of a rotating drum. Each towel holder carries a towel and also has a lever projecting therefrom. When the towel holder enters a vehicle drying sector, the lever contacts a fixed trip pin, causing the towel holder to rotate through an arc (in the same direction of rotation as that of the drum), pulling such towel holder's towel part way off the drum. This expedites unwrapping of the towels from the drum so that they can dry a vehicle. A guide rail below the drum limits the rotation of the towel holders so that the rear towel hangs lower than the towels forwardly thereof, to improve the distribution of towels on the vehicle.

Abstract: An isotope separation arrangement for separating a preselected isotope from a mixture of chemically identical but isotopically different molecules by either photon-induced pure rovibrational or vibronic selective excitation of the molecules containing the atoms of the isotope to be separated from a lower to a higher energy state, and a chemical reaction of the higher energy state molecules with a chemically reactive agent to form a chemical compound containing primarily the atoms of isotope to be separated in a physicochemical state different from the physicochemical state of the mixture of chemically identical but isotopically different molecules. The chemical compound containing the atoms of the isotope to be separated may be subsequently processed to obtain the isotope.

Abstract: A digital printout arrangement to print out a predetermined character response to a known coded input signal. The printout arrangement has a rotatably moveable platen for moving the medium upon which the printing is to occur in both forward and reverse directions. A printhead, which may be of the dot matrix type, is mounted on a carriage that moves reciprocatingly adjacent the platen. An incremental print ribbon is intermediate the platen and printhead to allow printing on the medium in response to activation of the dot printers in the printhead. The platen, printhead and print ribbon are digitally moved in response to digital control signals. A microprocessor, which comprises, essentially, a mini, special purpose computer is provided and has a storage means, a memory means and logic for generating the digital control signals in response to known input signals. The input signal may, for example, be of the serial by bit coded type and is converted into a parallel by character coded signal.
