Abstract: ABSTRACT OF THE DISCLOSURE           A sub-Nyquist sampled PCM NTSC color television signal obtained directly from a PCM encoded color television signal sampled at four times the color sub-carrier frequency by selecting every other sample in each line of the 4Fsc sampled television signal and introduc-ing a one 4Fsc sample displacement every two sequential television lines.  A sub-Nyquist sampled signal may also be obtained from an NTSC color television signal having a color subcarrier frequency Fsc by generating a sampling signal having a frequency of 2Fsc, the sampling phase of which shifts by 180° every alternate/time sequented televison line, and sampling the NTSC color television signal in response to the sampling signal.  Whichever of these two techniques is used to obtain the sub-Nyquist samples, the 4Fsc samples can be reconstructed when comb filters are used to remove alias components.  The process of converting 4Fsc encoded signals to sub-Nyquist and back to 4Fsc can be repeated without impairing picture quality beyond that introduced during the first conversion - reconversion process.

Title: Harmonic noise suppression in electromagnetic  flowmeter
Inventor: SCHMOOCK ROY F
IPC: G01F1/60

Granted: 1982-07-06
Abstract: ABSTRACT OF THE DISCLOSURE   An electromagnetic flowmeter in which fluid to be metered passes through a flow tube to intersect a magnetic field whereby the voltage in-duced in the fluid is transferred to a pair of electrodes mounted in the flow tube to yield a flow-induced signal.  This field is established by an electromagnet supplied with excitation current through a periodically-operated switch to create a magnetic field which during each operating cycle is alternately turned on and off or reversed in flux direction at a pre-determined drive frequency, as a consequence of which the signal includes undesirable noise components formed by even and odd harmonics of the drive frequency.  To suppress such harmonic noise, the flow-induced signal is applied to a converter that includes a pair of synchronous demodulators operating in phase opposition and so synchronized with the periodically-operated switch that one demodulator passes its output to an integrator dur-ing the first half cycle of the drive frequency only in a gating interval ti in which the magnetic field is turned on and is at a constant flux level, and the other demodulator thereafter passes its output to the same integrat-or during the second half cycle only in a gating interval t2 in which the magnetic field is turned off or is at a constant flux level in the reverse direction.

Abstract: ABSTRACT OF THE DISCLOSURE         In a sync generator for a color television system, a carrier signal having a frequency of four times the color subcarrier frequency 4fsc is counted down to produce a color subcarrier signal as well as vertical and horizontal synchronizing signals for an NTSC or PAL-M color system.  A color framing signal, which indicates a Predetermined point in the four sequentially repeating color fields making up an NTSC color signal, or in the eight sequentially repeating color fields making up a PAL-M color signal, is generated in response to the carrier signal, and a re-timing circuit establishes synchronism between the color subcarrier and the color framing signal.  Burst-flag and line odd-even signals are also produced for the PAL-M system.

Abstract: "INTERNAL COMBUSTION ENGINE AND OPERATING CYCLE"          ABSTRACT OF THE DISCLOSURE           A cylindrical rotor is mounted for rotation in a stator and the rotor includes a plurality of cylindrical bores disposed annularly around the axis thereof which are generally parallel to the stator bore.  Pistons reciprocate within these bores and connecting rods or links of the pistons engage within the profile of an annular cam secured to the stator so that as the rotor rotates, the pistons reciprocate due to the cam profile.  The cycle can be of a diesel type with a fuel injection or of the gasoline/air mixture type with conventional spark plugs.  Of importance, is the ease with which the expansion ratio can be made greater than the compression ratio thus util-izing more of the energy normally expelled and wasted in the exhaust gases with the conventional cycles.  The thermodynamic cycle in conjunction with the novel engine provides a dwell at the top or combustion stroke to provide a combustion temper-ature of not greater than 4000°C for improved engine efficiency and pollution control.  Engines operating in accordance with the present thermodynamic cycle utilize the formula:                              where:          k is the ratio of specific heats; C is the compression ratio; E is the expansion ratio; Tb is the temperature at the end of compression; and Tc is the temperature at the end of combustion and is from about 3000°C to 4000°R.
