Patent number: 5736636Abstract: A probe for determining the density of the material forming the wall of a wellhole provided with a selectively actuable source of gamma radiation pulses, including a pulse electron accelerator having an anode and cathode in axial alignment with a control electrode therebetween, the anode being connected to the output of the secondary coil of a Tesla transformer the primary coil of which is connected to the output of a capacitive high voltage charge unit. Emitted and scattered radiation are measured by first and second detectors the outputs of which are fed to a divider to derive a quotient of the outputs as a value representative of the density.Type: GrantFiled: June 10, 1996Date of Patent: April 7, 1998Assignee: BBI Gesellschaft fur Brunnen u.

Patent number: 4265157Abstract: A method and apparatus for producing sounds from one or more-time overlapg sequences of one or more electrical pulse signals having a frequency corresponding to the pitch of the sound to be produced from the signals holding the pulse width or pulse pause width in each sequence substantially constant for signals corresponding to a range of pitches of the sound to be produced. The pulse widths or pulse pause widths are then relatively abruptly changed over a short interval in pitch at the upper limit of the range. In this way, the shape of each pulse in a sequence and the phase between pulses in concurrent sequences which determine the timbre of the sound remains the same over the range of sounds to permit the method and apparatus to accurately duplicate the sounds of traditional musical instruments.Type: GrantFiled: July 14, 1978Date of Patent: May 5, 1981Assignee: Colonia Management-und Beratungsgesellschaft mbH & Co., K.G.Inventors: Jobst Fricke, Wolfgang Voigt, Jurgen Schmitz

Patent number: 4151368Abstract: Imitation sounds of musical instruments, especially brass wind instruments, re synthesized by using a pulse generator source driving an AGC amplifier channel having an AGC amplifier and formant filters and a limiter, the gain of the AGC amplifier being multiplicatively controlled by an instantaneously-varying control AGC signal derived from the output of the channel. The AGC signal can also be varied at the AGC point by the signal from a breath-sensing microphone in a whistle or pipe.Type: GrantFiled: August 6, 1976Date of Patent: April 24, 1979Assignee: CMB Colonia Management- und Beratungsgesellschaft mbH & Co. KG.Inventors: Jobst Fricke, Wolfgang Voigt, Jurgen Schmitz
