Abstract: Abstract A device is provided for increasing the power output of a gas turbine engine at the low ambient inlet temperatures which would otherwise produce a decrease in power. The device includes a conduit for bypassing a portion of the compressor discharge air around the combustor whereupon it is reintroduced back into the engine downstream of the compressor-driving turbine and upstream of the power turbine. if any. A valve is provided to increase the bypass flow rate through the conduit at low ambient temperatures, the increasing bypass flow permiting the engine to operate at a higher fuel flow and cycle temperature for the same compressor mass flow. The increased temperature with the same mass flow rate results in an increase in power.

Abstract: ABSTRACT OF THE DISCLOSURE A cutting head for rotary mowers, trimmers, and edgers for vege-tation, having a rotating body from which flexible flail-like filamentous cutting blades extend radially.  The device contains improvements over the cutting head described in United States Patent 4,097,941 dated July 4th, 1978. The flails are preferably of high-strength organic polymer such as nylon monofilament and exit from the rotating body through grommets.  The improved grommets are molded from a bearing material of plastic filled with powdered dry lubricant and metal particles.  The head has raised ramp portions along-side each grommet to protect the grommet.  Sharp-edged radial ribs on the top of the rotating body operate to deter weed and grass stems from wrapping and binding about the upper body.

Abstract: Abstract of Disclosure A dual bonding process to make single layered tools wherein a metallic workpiece is pre-etched so as to form cavities  in  the  surface  of  the  workpiece  for individually  receiving  diamond  or  other  abrasive particles to be bonded thereto.  The diamond particles are uniformly deposited  and densely bonded to the surface of said metallic workpiece by a metallic bonding matrix applied in a first plating bath.  A second selective plating of metal applied in a second plating bath more securely bonds the diamonds to the workpiece and provides the workpiece with a predetermined hardness for any selected grinding or cutting application.  In order to make multilayered tools, this dual bonding process may be repeated for each layer applied.

Abstract: CONTACTLESS TURNING GUIDE FOR RUNNING WEBS                  Abstract of the Disclosure A guide for contactless support of a running web as the latter changes directions. The guide is formed as a drum-like member having an arcuately curved surface which can be variable as to the length of its arc depending on the degree of turn or change of direction desired for the running web. A series of parallel grooves are formed in the arcuate surface of the drum-like member, which grooves extend in the direction of web travel. An air nozzle extends along the length of the drum-like member and at each end of the grooves in the drum-like member and pressurized air is fed through the nozzles so as to form a pneumatic cushion between the web and the arcuate surface of the drum-like member to thereby float the web in its turning direction over the drum-like member and without contact therewith. The grooves in the arcuate surface act as labyrinth seals in inhibiting transverse air flow out of the cushion and towards the edges of the running web. A barrier extends transversely of the direction of the web travel and across the grooves and blocks them intermediate their length to thereby form a barrier to the air flow in the grooves. This barrier ensures flow stability by preventing one slot from dominating the other which would lead to a non-symmetrical air flow pattern and reduced cushion pressure as well as result  in non-uniform cushion pressure.

The phase shifter control direction is decided by the sign of the two parameters.          One of them is difference between two antenna levels at the center frequency of the pass-band, and the other is the differ-ence of the combined signal levels at the extreme edges of the pass-band.  The control means comprises four detectors for detecting said levels, two subtractors for providing said level differences between them, and the control circuit for deciding the phase shifter control direction.
