Title: Dual path amplitude modulated rf amplifier
Inventor: STREETER ROBERT D
IPC: H03F1/02
Filed: 1991-03-12
Abstract: PHA 40.589                                      31.1.199 ABSTRACT: DUAL PATH AMPLITUDE MODULATED RF AMPLIFIER            An amplitude modulated RF amplifier using dual path modulation to increase operating efficiency. Both the RF drive to the amplifier and the DC power supply voltage to the amplifier are amplitude modulated. Preferably, the power supply modulation is accomplished with a high efficiency pulse width modulator circuit. To prevent phase shift distortion, the modulated DC output from the power supply is used both to power the RF amplifier and to amplitude modulate the RF drive to the amplifier. For maximum efficiency, the modulators are both non-linear. Maximum efficiency is realized with primarily supply modulation and some drive modulation providing the positive envelope modulation and primarily a non-linear RF drive modulation providing the negative envelope modulation. The use of primarily RF drive modulation for the deep negative modulation will reduce the amount of incidental phase modulation experienced, while having a nearly inconsequential effect on total efficiency of the RF amplifier.

Abstract: IMPELLER STRESS IMPROVEMENT THROUGH OVERSPEED                        ABSTRACT        A method for improving the capability of a body to withstand stress during rotation of the body by inducing at a selected location in the body a residual compressive stress which opposes the steady tensile stress produced by rotation.  The method comprises rotating the body at a succession of increasing peak speeds in excess of the design speed to induce tolerable yielding and residual compressive stress at each location experiencing higher steady tensile stress than the selected location.  The succession proceeds from the location experiencing the highest steady tensile stress above that at the selected location to the location experiencing the lowest steady tensile stress above that at the selected location.  Then the body is rotated to a still higher peak speed to induce tolerable yielding and residual compressive stress at the selected location.

Title: Methods and apparatus for sports training
Inventor: MCTEIGUE MICHAEL H
IPC: A63B55/60
Filed: 1992-01-22
Abstract: A method and apparatus for training a user to move in a desired movement pattern, especially for training a golfer (100) to swing a golf club. One or more sensors are placed adjacent the user, for example pressure, sensors (110) under the user's feet and/or pressure sensor (112) between the user's hands and a golf club. The sensors generate signals corresponding to the user's movement. A  comparator and signal generator (120) are used to compare a function of the user signals and a reference value, and to generate training signals which are communicated to the user, e.g. by means of radio frequency signals received by a headset (130) worn by the user. In this way, the user senses, during the actual movement, training signals which represent a relationship between the actual movement pattern and a desired movement pattern. Preferably, the comparator determines whether a function of the user signals is above or below a preselected and adjustable reference value, and the training signals undergo a distinct change when said function of the user signals crosses the reference value.

Title: Countergravity Casting Apparatus and Method
Inventor: CHANDLEY GEORGE D
IPC: B22D33/02
Filed: 1993-03-15
Abstract: A method for the countergravity casting of a melt involves placing a refractory mold in a vacuum chamber defined within a casting box where the mold may be optionally surrounded by support particulates in the vacuum chamber. The mold includes a mold cavity and a serpentine melt inlet passage formed by nested refractory members below the mold cavity and in melt flow communication therewith. The serpentine melt inlet passage is communicated with a fill tube extending from the casting chamber toward an underlying source of melt. The mold/chamber and the source are relatively moved to engage the fill tube and the source. A differential pressure is applied between the mold cavity and the source to urge the melt upwardly through the fill tube and serpentine melt inlet passage into the mold cavity. The mold/chamber and the source are then relatively moved to disengage the fill tube and the source after the mold cavity is filled with the melt. The mold/chamber as a unit is rotated in a direction that the serpentine melt inlet passage prevents runout of melt from the mold cavity until the mold/chamber are inverted.
