Abstract: 251,001. Aerozon Air Conditioning Co., Ltd., Pratt, W. T., and Lipscombe, H W. J. Jan. 19, 1925. Air, moistening. - Means for controlling the humidity of air is actuated by a sensitive element, such as a band of cotton, located in a tube or casing placed in the room, and means are provided to circulate the air in the vicinity through said tube and past the element. The element 1 is clamped at its ends to blocks 2, 3 and passes over a pulley 2a arranged in a tube 25 through which air is circulated either by a fan 26, Fig. 1, or by a divergent jet of gas issuing from a nozzle 28, Fig. 3. The block 3 is connected to a pivoted lever 4 near its pivot 5, and at the other end the lever 4 is connected to a pivoted lever 6. The end of the lever 6 remote from its pivot 7 is adapted to engage either of a pair of contact arms, pivoted at 10 and each held against a stop 12 by a spring 11. If desired, the lever in its neutral position may engage contact studs on either side, and require a definite movement to break a contact, or the lever may contact progressively with a number of studs arranged on one or both sides of the lever. The arms 9 are connected to terminals 17, 18 respectively, and the lever 6 to a terminal 19, the said terminals being connected to a double solenoid, which controls a cock in a pipe supplying liquid to an airconditioning apparatus such as described in Specification 220,703.

[Also in Divisions B5 and B6] A spiral of deformable strip material e.g. metal, is formed by feeding a strip of the material against or through means for curling the strip into spiral form, the curved leading portion of the strip being brought into contact with an abutment so as to form an open spiral. Strip 1 is fed by rollers 2, 4 against the concave edge of a plate 3 which curls the strip downwardly to form a spiral the curled strip passing from the plate 3 to an abutment plate 5, frictional contact with which serves to open up the spiral. In another embodiment, Fig. 3c (not shown), the strip passes upwardly from the rollers 2, 4 and plate 3 to engage an abutment plate 5. In another embodiment, Fig. 5c (not shown), the strip is fed by a belt (8), running around rollers (7), (9), (10), up around the roller 2 to engage an abutment plate 5. The rollers 2, 6 of the above embodiments may be of polygonal cross-section. The abutment plate 5 may be adjustable in height. The formed spiral may be severed from the strip by a blade 12 on a rotating arm 11, Fig. 6. In a further embodiment, Figs. 8, 9 (not shown), strip is curled downwardly by endless belt (8) and roller 2 to engage an abutment plate 5. The formed spirals may be guided by a shoot to stand on edge on an endless conveyer. A plurality of strips may be curled side by side. Apparatus without the abutment plate 5 is also disclosed.

Title: Improvements in or relating to navigation aiding radio systems
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: G01S5/10
Filed: 1949-01-27
Abstract: 683,687. Radio navigation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 25, 1950 [Jan. 27, 1949], No. 2309/49. Class 40 (vii). In a continuous wave phase-compression radio navigation system comprising two spaced transmitters one transmitter is arranged to radiate signals of two frequencies symmetrically disposed with respect to a given mean frequency which is large in relation to the spacing of each therefrom and the other transmitter is operated to transmit signals either of the mean frequency or of a further two frequencies also symmetrically disposed with respect to the given mean frequency and differing therefrom by a frequency small in relation thereto. In practice the mean frequency is preferably a carrier and the symmetrical frequency signals sidebands resulting from balanced modulation. The carriers at the stations must be phase synchronized. The invention also contemplates the use of three or more stations providing at least two pairs of signals for phase comparison and giving positional information over a considerable area, in such a system the given mean frequency of all the stations is preferably the same so that the frequency requirements are only a single band. At the receiver phase comparisons are made between signals of double the mean frequency obtained by adding the two frequencies from the stations radiating two symmetrically disposed frequencies or by frequency doubling if the mean frequency only is radiated. In a three-station position determining system spaced stations A1, A2 and A3 synchronized by means not shown but represented by the chain dotted lines radiate respectively signals of the carrier or mean frequency F0, FO -f1, and FO - f2 and F0+f2. The signals at stations A2 and A3 are obtained by modulating F0 with f1 and f2 respectively and suppressing the carrier F0. At the receiver whose position is to be determined the signals are separated by filters and the F0 signals multiplied in frequency at X to give a signal of 2F0, the F0-f1 and F0+f1 signals are added at Y and the F0-f2 and the F0+f2 signals are added at Z also giving signals of 2F0. Phase meters P1 and P2 comparing the outputs of X and Y, and Y and Z, respectively give indications from which the position of the craft can be read off on a suitably marked chart. In a modification of this embodiment (Fig. 3, not shown), station A may radiate signals of frequency F0- f and F0+f and these signals being separated by filters at the receiver may be added at X to give an output of frequency 2F0. Specification 683,688 is referred to.
