Abstract: ABSTRACT OF THE DISCLOSURE        A process and apparatus for applying stretchable plastic film to loads for containment of the loads using two connected sets of powered rollers driven at different peripheral speeds to elongate the plastic film beyond its yield point and simultaneously connecting the stretched film to a rotating load whose surface is moving at approximately the same rate of speed as the surface of the faster and final of the two sets of rollers.  A powered or force loaded film accumulator such as a dancer bar can be added to compensate for corners of the load where significant length-width distortions exist.  In addition, a web narrowing device may be placed upstream or downstream from the rollers to reduce the hazard of edge tear under high elongation forces.  Closure of the film ends can be accomplished by a mechanical closure mechanism.

Abstract: Abstract of the Disclosure A method of coating a core sample in which a distillate such as petroleum jelly is applied to the exterior surface of the sample.  A cylindrical mold is partially filled with a plastic mixture of hardenable epoxy resin and hardener therefor, and one end of the core sample is slowly inserted into the mold under a pressure which perferably is not more than about 50 pounds per square inch.  In some cases the inserted end of the sample is pre-coated with the plastic mixture.  As the insertion of the sample is continued, the mixture flows up the side of the sample and covers the opposite end.  The coating is cured by maintaining it in the mold at room temperature for a period of time sufficient to enable the resin to set up and then by holding it at an ele-vated temperature for at least about eight hours.  Upon the removal of the coated sample from the mold, the ends are cut off to expose the sample material.

Abstract: RIBBON LIFT AND FEED MECHANISM FOR A TYPEWRITER                 Abstract of the Disclosure A ribbon lift and feed mechanism for a typewriter/ printer (10) in which the print ribbon cartridge (15) has deflectable arms (16a, 16b) for placing the ribbon (13) in a position confronting the platen (11) of the typewriter (10).  On the platform (40), supporting the ribbon cartridge (15), is a shuttle (50) which is remotely oscillated as by a drive motor (90) on the frame (12) of the typewriter (10).  Translation of the shuttle (50) and the cam (66) associated with the shuttle (50) effects movement of cam follower (66a) engageable with the cam (66), causing the deflectable arms (16a, 16b) of the cartridge (15) to oscillate between a rest and elevated position to place different portions of the print ribbon (13) intermediate the type element (23) and the platen (11).  The shuttle (50) also carries ribbon feed drive means (85) which cause an incremental feed of the ribbon (13) after the ribbon has been struck at multiple elevated positions.  More-over, by placing a correction ribbon cartridge (30) be-neath the ribbon cartridge (15), another cam (70) on the shuttle can effect platform (40) elevation when it is desired to dispose the correction ribbon (30) inter-mediate the printing element (23) and the platen (11). This action occurs as a result of the oscillation of the shuttle (50).

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method for controlling the flight-position of an aerodyne (aerodynamic body whether self-propelled or projected) and/or for activating a useful load transported by the said aerodyne, and to an apparatus for the execution of the method.  Sound-waves are radiated, preferably in the form of a beam, from at least one transmitting-receiving device arranged in the aerodyne.  The sound-waves are reflected from the aerodyne's environment, for example from the surface of the earth.  The reflected sound-waves are picked up by the receiving device and, after being converted into electrical signals, are further processed.  The distance between the aerodyne and the surface of the earth, for example, can be determined by measuring the transit-time of the sound-waves.  If the aerodyne deviates from a predetermined flight-path, control-surfaces are actuated by a control device for the purpose of correcting the flight-path.  Moreover, the transmitting-receiving device, and the control device, may be used to bring the useful load, transported by the said aerodyne, into operation.
