Title: Weather outline contour generator
IPC: G01S7/292
Filed: 1969-10-08
Abstract: 1,234,704. Radar. BURROUGHS CORP. 8 Oct., 1969 [15 Oct., 1968], No. 49397/69. Heading H4D. In a radar system for generating signals representing weather outline contours, logarithmic video echo signals are subject to swept gain, a root-mean-square estimate of the level of weather clutter is formed and if poor estimates are made consistently a system parameter is adjusted to better them. The output of swept gain unit 11 is fed to a delay line with taps spaced by one range cell and connected to a summing amplifier 17 to give an estimate of the mean value for the present range sweep. This estimate is modified by a unit 19 (see below) and the modified estimate is encoded and sampled each ¢ nautical mile by a unit 23 which converts the analogue signal input to digital form and holds the most significant four bits. Unit 25 subtracts from the encoded estimate the stored estimate in memory 27; the difference is weighted and added to the estimate from the previous sweep, the resultant being stored in the memory until the same range cell on the following sweep receives a new estimate. The weighting is determined by a unit 29.

The surface-active agent may suitably be anionic, cationic or non-ionic, e.g. a salt of an alkaryl sulphonic acid, or quaternary ammonium halide or a condensate of a 1,2-alkylene oxide with an alcohol or a phenol.  The alkali metal salt of the 1,1-dialkylcyclohexane-3,5-dione is preferably prepared in situ by dissolving the dione in aqueous alkali metal hydroxide, and its reaction with the alk-2-enyl bromide is suitably carried out in the presence of copper powder.  This reaction is also applicable for the preparation of known compounds wherein the 1,1-positions are unsubstituted, i.e. for the preparation of 2-alk-21-enylcyclohexane-1,3-diones and 3-alk-21-enoxycyclohex-2-en-1-ones.  3,3-Dialkylalkanoic acids are prepared by reacting the alkali metal salt of a 1,1-dialkylcyclohexane-3,5-dione with an alk-2-enyl bromide, separating the products, which comprise the alkali metal salt of a 4-alk-21-enyl-1,1-dialkylcyclohexane-3,5-dione and a 5-alk-21-enoxy - 3,3 - dialkylcyclohex - 5 - en - 1 - one from each other, acidifying the alkali metal salt, heating the resultant 4-alk-21-enyl-1,1-dialkylcyclohexane-3,5-dione with hydrazine in the presence of an alkali metal hydroxide and an organic hydroxylic solvent, to give an alkali metal salt of a 3,3-dialkyl-5-oxoalk-8-enoic acid hydrazone, and then heating at 180-250 DEG  C. and acidifying to give the 3,3-dialkylalk-8-enoic acid before finally hydrogenating.  Alternatively, the hydrogenation can be carried out at the intermediate stage on the 4-alk-21-enyl-1,1-dialkylcyclohexane-3,5-dione to give a 1,1,4-trialkylcyclohexane-3,5-dione before the treatment with hydrazine.

A pilot-actuatable control panel, Fig. 1, comprises on/off switch 11 which also includes a deferred-item position, a start-reply bar 12 which controls a switch spring-biased to an open position, an item-repeat push button switch 13, also spring biased to open position, a manual reset push button switch 14, a volume control knob 15 and a selector switch 16 whereby a desired pre-recorded message may be selected, an indication of the selected message being displayed in a window 17. The pre-recorded messages may enumerate pre-flight or in-flight checks to be made by the pilot and these would be selectable by switch 16. Other messages would issue duties to be performed in an emergency, e.g. in the event of fire and for these detecting apparatus on the aircraft would transmit signals automatically to the tape recorder to run the tape to the correct position to transmit the appropriate message to the pilot and if necessary to energize an emergency broadcast radio transmitter to transmit an emergency signal on the universal emergency frequency. Fig. 3 shows a general representation wherein four inputs, T1, T5, T6, T8 out of eight from eight tape tracks and two out of three emergency inputs T6, T8 are displayed. S1 and S5 are shown as examples of manually selected inputs from switch 16 respectively coupled to one input of AND gates 25 and 26, the other inputs being a signal EM which is the inversion of an emergency signal so that in an emergency the AND gates coupled to switch 16 are disabled. The outputs from gates 25, 26 are respectively coupled to the enable leads of gates 27, 28 which have input signals from the playback heads of tape tracks T1 and T5. Emergency tracks T6-T8 are coupled to gates similar to gate 27, e.g. 31 and 32 which have enabling inputs from emergency sensors. The outputs of the gates are coupled to a node 30 in turn connected to a pre-amp 34 and amplifier 35. Volume control knob 15 controls a variable resistor 36 thus controlling the volume of the signal fed to a speaker 39.
