Abstract: A method and apparatus for milling and/or broaching within a wellbore. A flexible broach runs into the wellbore and is located adjacent a portion of the wellbore to be broached. The broach reciprocates axially within the wellbore and removes at least part of the portion to be broached. Weight may be coupled to the broach, thereby applying a resultant side load for broaching an offset portion of the wellbore. The broach comprises a flexible member that may be a bare cable. When an abrasive material is disposed on an outer surface of the flexible member, the flexible member may be a cable, a continuous rod, or pressurized coiled tubing. Alternatively, sleeves positioned on the flexible member may have an abrasive material on their outer surface. A rotational mill that is either coupled to the broach or run in separately from the broach can further mill the wellbore.

Abstract: The disclosed motor control device is responsive to control pulses received from a remote transmitter to provide switched duty cycle controlled power to the electric motor which drives the model, and provides neutral and fully proportional forward and reverse speeds while using only a single radio frequency channel. The controller is small in size and weight, is efficient, dissipates very little power, and employs no servo driven elements. The circuit is constructed to ensure motor shut-down in the event of loss of transmitter signal, or of receiver failure.

Abstract: An electronic circuit triggered by pulses derived from the rhythm pattern generator of an electronic organ simulates the sound of a group of people clapping hands by producing in bursts at least two different sound signals of differing characteristics and combining the signal bursts in a predetermined pattern which causes them to occur in close time proximity to each other but not at the same time. When the combined signal is acoustically reproduced, the resulting sound is simulative of that produced by a group of people clapping their hands in unison.

Abstract: A device for electronically simulating vibrato and tremulant effects and the radiation effects produced by a rotary loudspeaker with the aid of two loudspeakers, in which a musical tone signal is applied to a variable delay device associated with one of the loudspeakers. The frequency modulated signal produced by the variable delay device is also subjected to amplitude modulation, controlled in synchronism with the variable delay device, and the resulting composite signal applied to the other loudspeaker. Additionally, the high frequency components of the frequency modulated signal from the variable delay device are summed, in and out of phase relationship, with the composite amplitude modulated signal to simulate the effect of a rotating high frequency horn radiator.

Abstract: A one key chording system for an electronic organ of the type in which single contact keyswitches for D.C. keying of tone signals are employed. The keyswitches of a first group are connected to a common bus to which is also connected a mode select circuit for selectively applying thereto a D.C. potential of either positive or negative polarity. In the disclosed embodiment, when a negative potential is applied to the common bus a signal from an actuated keyswitch in said first group operates one of a plurality of chord logic circuits to produce a plurality of auxiliary keying signals which operate tone signal keyers for tone signals corresponding to a musical chord. An alpha-numeric display disposed adjacent to the keyboard indicates the name of the chord being played by the one key chording system.

Abstract: An automatic rhythm system for an electronic organ adapted to enable a plurality of percussive instruments and a plurality of accompaniment and "Walking Bass" instruments normally played by the pedals of the organ includes two separate rhythm pattern generators each storing a plurality of rhythm patterns, the outputs from one of which enables selected percussive instruments and the outputs from the other enabling little used percussive instruments and the "Walking Bass" normally played by the pedals. A plurality of rhythm select switches are directly connected to respective input terminals of the first rhythm pattern generator, and to ensure against generation of musically unacceptable combinations of rhythm patterns when a combination of rhythm patterns is selected, the rhythm select switches are connected through control logic to the second rhythm pattern generator, the control causing the second rhythm pattern generator to play only the first turned on rhythm pattern of a combination of patterns.
