Abstract: An improved mouthpiece for use with single reed woodwinds to enable the generation of improved sound quality from the standpoint of enhanced harmonic tone generation. The configuration of the mouthpiece in the area overlying the opening which underlies the vibrating end of the reed is significantly modified relative to prior art construction to enable the reed to vibrate a column of inducted air as the same passes through a relatively narrow channel, following which the column enters a channel of substantially greater cross-section before exiting to the neck of the instrument. As contrasted with the prior art construction in which the area immediately above the vibrating portion of the reed defines an air column of greater cross-section, the constricting of the column at the point in which vibration is imparted generates additional harmonics which significantly affect the quality of the tone.

Abstract: A vacuum brake power booster and a process is disclosed in which a precise adjustment of the power boost startup characteristic is achieved. The adjustment is carried out as a final step in the manufacture of the booster adjusting the distance between the valve piston and an elastic reaction distance.

A pre-established input force is exerted on the piston rod while simultaneously measuring the output force exerted by the push rod, and the axial length of the valve piston is modified until the measured output force is within a pre-established range. The adjustment is carried out by modifying the length of a two piece valve piston or by temporarily extending a rod within the valve piston until a correct output force is reached and thereafter removing the rod and inserting a transmission pin of a length determined by the extent of travel of the rod at the point at which the desired output force was attained.

Abstract: A control fin actuator (28) for a guided missile (20) includes a pressure actuator (40) having a slidable piston (44) inside a housing (42). Rolling diaphragm seals (50, 56) of the top piston face (46) and the bottom piston face (48) to the inside wall of the housing (42) divide the interior of the housing (42) into at least two chambers (54, 58).
