Abstract: Abstract There is disclosed a combination rotary and percussive portable tool driven by an electric motor.  The percussive means includes a reciprocating cylinder having embodied therein a reciprocatable piston striker.  The cylinder is mounted in a guide tube which is spring loaded by a spring positioned between an internal wall in the housing and a cap removably mounted over an opening of the housing. The opening provides access to the housing in order to remove the guide tube and spring.  With guide tube resiliently mounted in the housing, the guide tube and its interface with the housing is much less affected by the vibration and thermal conditions developed during operation of the tool.  In addition, the tolerances required to mount the guide tube in the housing do not have to be kept as tight as they would have to be is a conventional mounting arrangement using welds or other rigid fastening means were used.

Abstract: ABSTRACT OF THE DISCLOSURE           A retractable center guide and vertical and lateral load restraint for a cargo carrying aircraft.  The devices are mounted along the center line of the aircraft and in erect position include laterally extending arms adapted to overlie the edges of load carrying structure such as pallets.  The devices are pivoted for swinging about axes extending trans-versely of the aircraft so that if a device is in the path of an advancing load carrying structure, it will be pivoted to retracted position, thus avoiding damage to the device or load carrying structure.  Resilient means are provided effectively to maintain the device either in erect or in retracted position, or the resilient means may restore the device to an erect position if it is released after being moved to retracted position.  The series of devices together with guide surfaces at the side of the aircraft, constitute an elongated guideway along which load carrying structure may be advanced.  Finally, in erect position with load carrying structure at the side of a device, the device operates as a restraint against lateral movement of the load carrying structure.

Abstract: ABSTRACT OF DISCLOSURE.     In a method of producing steel from solid ferrous material in a converter, the ferrous materials is preheated by the introduction into the converter of oxygen and fuel through at least two nozzles arranged in the converter side walls at relatively different heights in the region of the converter occupied by the subsequently produced steel melt.        During the preheating phase of the solid ferrous materials the nozzles operate as oil-and/orgas/oxygen burners, but when the melt has risen to the level of the lower nozzle(s), the latter is switched to the introduction of powdered carbonaceous fuel and oxygen.   Thereafter, when the melt has risen to the level of the upper nozzle(s), oxygen and, at least for some of the time, carbonaceous fuel are introduced into the melt through each of said at least two nozzles.
