Patent number: 4516322Abstract: A mechanically operated cutter assembly adapted to shear bar or rod stock, such as bone pins, even though both ends of the rod are fixed, along a plane perpendicular to its axis, includes a body member having an elongated interior channel within which a rod carrier and cutting plug are slidably mounted, the body having a slot disposed transversely to the longitudinal axis of and intersecting the interior channel for permitting access of the rod to the cutting plug. The cutting plug has a transverse passageway contoured to fit a portion of the periphery of the rod to be sheared which, in a first longitudinal position is aligned with the rod-receiving slot. The cutting plug is adapted to be moved to a second longitudinal position at which the passageway is out of registry with the slot, whereby a rod carried in the passageway is severed.Type: GrantFiled: September 27, 1982Date of Patent: May 14, 1985Inventor: Allen P.

Patent number: 4516257Abstract: A triphonic sound system in which three independent stereophonically related audio frequency source signals L, R and C are combined to derive three other audio frequency signals M, S, and T which respectively comprise (L+1.4C+R, (L-R) and (-1.4C). In a preferred transmitter embodiment, useful in television broadcasting, the audio signals S and T modulate two quadrature-related sub-carriers of the same frequency to develop two double-sideband, suppressed-carrier signals, the frequency of the subcarriers being sufficiently high as to assure a frequency gap between the lower sidebands of the modulated subcarrier signals and the audio frequency signal (L+1.4C+R). The aforementioned signals, and a pilot signal having a frequency which lies within the frequency gap, are combined and frequency-modulated onto a high frequency carrier for the purpose of transmitting the same to one or more remote receivers.Type: GrantFiled: April 5, 1984Date of Patent: May 7, 1985Assignee: CBS Inc.Inventor: Emil L.

Patent number: 4485483Abstract: An FM stereophonic radio broadcasting system in which stereophonically related audio frequency source signals L and R are matrixed to obtain stereophonic sum and difference signals M and S, respectively. At the transmitter, the difference signal, is compressed, and the conventional difference signal and the compressed difference signal modulate respective quadrature-related sub-carriers of the same frequency to develop two double-sideband, suppressed-carrier signals, the frequency of the sub-carriers being sufficiently high as to assure a frequency gap between the lower sidebands of the modulated sub-carrier signals and the sum signal M.

Patent number: 4403256Abstract: The disclosed picture stabilizing system detects and measures picture unsteadiness in recorded or live video caused by an unsteady television camera and automatically eliminates the unsteadiness without destroying intentional panning and tilting of the camera. This is accomplished by selecting camera motion references within the camera field of view consisting of one horizontal edge and one vertical edge of an object which will normally be stationary, such as a door, a window, or a piece of furniture. The stabilizer "locks" onto these edges, continually measuring their motion from field to field and utilizing a frame store, makes the necessary vertical and horizontal corrections to the overall picture to eliminate such motion. The system is able to correct for movement due to random unsteadiness without interfering with planned camera movement.Type: GrantFiled: November 10, 1981Date of Patent: September 6, 1983Assignee: CBS Inc.Inventors: Richard R. Green, Henry W. Mahler, John E. Siau

Patent number: 4397210Abstract: 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.Type: GrantFiled: December 11, 1981Date of Patent: August 9, 1983Assignee: CBS Inc.Inventor: Robert A.

Patent number: 4300435Abstract: In an electronic musical instrument, such as an electronic organ, certain organ voices are synthesized by applying a tone signal to a voltage controlled low-pass sharp cutoff filter, the pass characteristic of which has a relatively sharp knee and a rapid rate of rolloff, thereby to sharply attenuate the harmonics contained in the tone signal which have frequencies above the cutoff frequency. The filter works on the principle that by switching one or more frequency-determining resistors in and out of the filter network at a rapid rate and varying the time on versus the time off, the effective value of the resistance varies to thereby alter the cutoff frequency and the character of the resulting sound signal. In accordance with the present invention, precise control over the switching duty cycle is achieved by establishing a reference voltage to which is added a voltage increment according to a binary weighting determined by selection of a particular organ voice.Type: GrantFiled: November 24, 1980Date of Patent: November 17, 1981Assignee: CBS Inc.Inventor: George F. Schmoll, III
