Filed: 1976-07-30
Abstract: 1516253 Condensing water from atmosphere TECHNICO DEVELOPMENT & FINANCING SA 30 July 1976 [9 Aug 1975] 31976/76 Heading BIB Apparatus for obtaining water from the atmosphere comprises a heat pump 10 having a closed circuit which passes through chambers 11, 12 and includes compressor 19 and valve 14, the arrangement being such that when valve 14 is in one position the heat pump cools chamber 11 and supplies heat to chamber 12 and vise versa when the valve 14 is in a second position. As shown each chamber is provided with a valved inlet 30 or 31, a respective fan 13, a respective outlet 21 provided with suction device 16a or 16b and filter 28, and a respective sensor 24. In use when the heat pump is cooling chamber 11 valve 17 is open and the air drawn into chamber 11 is cooled to produce water and/or ice. When a certain amount of water and/or ice has collected on wall 23 of chamber 11, the sensor 24 actuates control means 25 to close valve 17, stop fan 13 associated with chamber 11, change the position of valve 14, open valve 18 and start fan 13 associated with chamber 12 so that water and/or ice is produced in chamber 12, the heat extracted in chamber 12 by pump 10 being used to melt any ice in chamber 11. The water produced in each chamber is discharged to reservoir 15. Water discharged from reservoir 15 may be dosed with minerals at 27. The compressor and fans may be driven by I.C. engine or electric motor 20 or by hand crank 26. The chambers may be supplied with air by a compressor.

Title: Improvements in or relating to apparatus for the control of the timing of recurrent signals
IPC: H04L25/04
Filed: 1939-12-13
Abstract: 589,228. Pulse generating circuits. BLUMLEIN, A. D., and WHITE, E. L. C. Dec. 13, 1939, No. 32159. [Class 40 (v)] Pulses of adjustable and known timing are produced from sources of frequency f and nf by a device giving an output only when energized by both sources simultaneously. Means are provided to adjust the timing of each of the sources so that the timing of the pulses is determined by the timing of the higher frequency so that greater precision in timing is obtained. A third source of frequency mnf may be provided and combined with the product of frequencies f and nf to obtain still greater accuracy in the timing of the generated pulses. Fig. 1 shows a valve V from the anode of which pulses are obtained and the timing is adjusted by goniometers GN1, GN2 arranged between the sources 01, 02 and the valve grids G1, G2. The output from oscillator 01 is fed to the goniometer GN1 in phase quadrature directly and through the phase changing network PI and to a limiter L1 to produce a square waveform and a differentiating network D1 and utilized directly or through a pulse generator PG1. The oscillations are also fed through limiter L<1>, differentiating network D<1> and a frequency divider FD, which may be of the kind described. in Specification 471,731, to oscillator 02. The output of oscillator 02 is applied to grid G2 through goniometer GN2. Instead of adjusting the timing through inductive goniometers, capacitive goniometers may be used or time-delay networks. When time-delay networks are used they may be folded to bring their ends adjacent and are terminated to prevent reflection, and the timing adjusted by rotating a pick-up electrode either making contact or giving capacitive coupling. A second delay network capacitively coupled to and rotatable with reference to the first may alternatively be used. The timing may alternatively be controlled by a saw-tooth voltage generator, Fig. 2, in which the pulses are applied to a valve VI, normally biassed to cut-off and arranged to discharge condenser C2 on receipt of a pulse. The voltage across condenser C2 is applied to one of a pair of valves V2, V3 having a common cathode resistance as described in Specification 482,740. In this way the anode current of both valves will change when the grid voltage of V2 exceeds that of V3 and pulses may be obtained from resistance R3 or resistance R5, the timing depending on the potential applied to the grid of the valve V3. The generated pulses may be used in a system as described in Specification 585,907.
