Title: An equalizing pulse removal circuit
IPC: H04N5/08
Filed: 1981-02-20
Abstract: A composite sync signal separated from a video signal is applied to a circuit which removes equalizing pulses, so that only horizontal sync pulses are produced at the output. Clock pulses of a frequency 175/4 fH (fH: a horizontal scanning frequency and about 15,734 KHz), for example, are frequency-divided into a signal of a frequency 175/256 fH by a frequency divider having D-type flip-flop circuits (FF1 to FF6). A reset circuit having NAND circuits (16, 17) processes the frequency-divided output signal, (f), a composite sync signal (d) delayed by shift register (15) and the inverted composite sync signal (e), to form pulses (g) in synchronism with the horizontal sync pulses which reset the frequency divider. At the same timing of the pulse generation from the reset circuit, a gate pulse generating circuit having D-type flip-flop circuit (FF7) generates pulses (i) of width longer than the pulse width of the horizontal pulses, which in turn are applied as the gate pulse to the output gate circuit (18). <IMAGE>

Title: Process for the manufacture of methyl tert.-butyl ether
IPC: C07C41/06
Filed: 1981-07-13
Abstract: A process is disclosed for producing methyl tert.-butyl ether wherein n-butane is isomerized to isobutane which is then catalytically dehydrogenated to form an isobutane/isobutene mixture, while natural gas is reformed to form synthesis gas containing CO and H2 which is in turn converted to methanol, the resulting methanol and isobutene in the isobutane/isobutene mixture being etherified to form methyl tert.-butyl ether. Isobutane is then separated from the resulting etherification mixture and is recycled to the dehydrogenation stage. Secondary product gases from at least one of the isomerization, dehydrogenation and methanol synthesis stages are combusted and used to produce superheated steam at high pressure which is expanded to a medium pressure by expansion through at least one first back-pressure turbine coupled to a corresponding compressor or compressors for compression of at least one of the synthesis gas and of the dehydrogenation product gas, while resulting medium pressure steam is expanded in turn through at least one second back-pressure turbine to low pressure steam in excess of atmospheric pressure, such low pressure steam being utilized for heating process apparatus.

Title: Wind shear detection by laser doppler velocimetry
Inventor: WOODFIELD ALAN ANTHONY
IPC: G01S17/95
Filed: 1983-06-29
Abstract: In apparatus for the early detection of oncoming wind shear, without false indications arising through turbulence, as might be installed in an aircraft 10, a forward looking laser speed sensor 11 provides a signal 12 containing information on air velocity over a range +/-L of distances about a measurement distance X, which is subject to spectrum analysis 15, to identify all velocities present in a time sample of the signal 12. These velocities are further processed 17 to establish the air velocity at substantially the measurement distance X, and the highest and lowest velocities present over a distance range +/-L. A time sequence of such results is examined to determine if the rate of change of velocity is too high and too prolonged; if these exceed a hazard level limit, computed 13 from the prevailing conditions, a wind shear hazard is considered present. <IMAGE>
