Patent GB-317068-A (GB)
IPC: G01S13/34
Filed: 1929-03-16
Abstract: 317,068. British Thomson-Houston Co., Ltd., (Assignees of Bentley. J. 0.). Aug. 10, 1928, [Convention date]. Indicating proximity of earth.-The height of aircraft above the earth is indicated by radiating towards the earth, from the craft, high-frequency oscillations of varying frequency and combining the oscillations reflected from the earth with oscillations radiated directly from the craft to produce a current of beat frequency. Arranged on the aircraft is a transmitter 1 and a receiver 2, the transmitter radiating from an antenna 4 waves which travel downwards to the earth and are reflected on to an antenna 7 on the receiver. The received waves may be amplified and heterodyned with a wave received from the transmitter 1 directly, as through a circuit 8, the beatfrequency current being supplied to headphones or other frequency-responsive devices 11. In the transmitter 1 is an oscillation-generating valve 14 having a tuned circuit comprising a capacity 15 and an inductance 16, a portion of which is included in the primary winding of a transformer 17. In shunt with the condenser 15 is a linearfrequency condenser 19 the rotor of which is driven by a motor 12, so that the frequency of the oscillations generated by the valve 14 is caused to vary cyclically. These oscillations are supplied to the antenna 4 through a winding 20 on the transformer 17 and a commutator 21 insulated from the condenser rotor at 9 and having half its periphery formed of non-conducting material. A portion of the oscillations produced are supplied through a circuit 8 to the primary winding 23 of a transformer 24 which has a second primary winding connected to the receiving antenna 7 which receives waves reflected from the earth. The secondary winding of the transformer 24 is connected to a rectifying valve 25, and is tuned to the frequency of the received waves by a linear-frequency condenser 27, the rotor of which is driven by the motor 12. so that the frequency to which the receiver is tuned is equal to and varies synchronously with the frequency of the transmitted waves produced by the oscillation generator 14. The circuit 8 may be omitted if the capacitative coupling between the antennae 4, 7 is sufficient.

Abstract: 375,800. Heating water by electricity. PETRIE, D. G., 40, Guessens Court, Welwyn Garden City, Hertfordshire. March 20, 1931, No. 8656. [Class 39 (iii).] Some or all of a number of tanks, all arranged exteriorly to one another, are fitted with heating elements which are not all of the same capacity. The elements may increase progressively in capacity throughout the series of tanks or the arrangement may comprise an element of large capacity in the outlet tank and elements of small and equal capacities in the other tanks. In the Figure tanks 1, 2 are fitted with elements 21 controlled independently by thermostats 22 adjusted to different temperatures. The tanks are a sliding fit in guides mounted on a frame 8. The lower ends rest on bars 3 mounted on a frame 4. The frames are secured to supporting straps 5. The tanks are lagged and enclosed by a rectangular casing 6. The water enters tank 1 at the bottom through a valve 10 and is discharged from the top of tank 2 through a pipe 13. A pipe 12 connects the top of tank 1 and the bottom of tank 2. A connection 20 equalizes the pressures in the tanks. A cock 26 carrying a test pipe 24 is fitted to each tank and may be removed to empty the tanks. In a modification there is no inlet valve, but a valve is fitted to the outlet. In this case the pressure equalizing connection 20 opens into an expansion pipe. In another modification the inlet and outlet pipes enter the tanks through their upper ends. In a further modification a feed tank with a ball cock is arranged in the casing above the tanks. Other arrangements comprise tanks arranged horizontally or one above the other. Two further arrangements employ a primary tank connected to two independent tanks. In one case the tanks are side by side and in the other the primary tank is arranged above the other two.

Title: Improvements in and relating to coated composite sheet material
IPC: B41N1/12
Filed: 1920-03-24
Abstract: 163,552. Alexander, A. E., (Stokes, J. P.). March 24, 1920. Drawings to Specification. Printing-surfaces.-In making composite sheet material which can be moulded and used for printing surfaces &c. consisting of a fibrous body impregnated with a liquid cementitious material capable of setting or hardening in two stages under the action of heat, such as those obtained from phenols by condensation processes, and coatings of cement, the body is heated to such an extent before moulding that instead of remaining soft it becomes dry and crisp. For this purpose the body, which may be made of blotting paper, long fibred chip-board, &c. is soaked in a solution of the cement, passed between rollers to press out excess liquid, and freed from the solvent by heating. Several layers of this sort may be joined together by glue, or a single layer may be used. The sheet thus formed is coated on both sides with a layer of cement containing a high proportion of a filler such as lamp black and heated until the cement is nearly hard. Coatings of cement containing a lower proportion of filler are then applied and the sheet heated until the latter coatings are of such consistency as to be moulded readily by pressure. The sheet is then moulded as desired in a heated press, until the cement is completely set. The lamp black may be replaced by other fillers, such as wood flour, aluminium oxide, barium sulphate, and silex.

Abstract: 1,060,121. Laminates and laminating. DUFAYLITE DEVELOPMENTS Ltd. Feb. 1, 1965 [March 2, 1964], No. 8688/64. Heading B5N. A honeycomb laminate is made by advancing a band of structural honeycomb material, made of paper or thin cardboard, in the expanded state, feeding paper into contact with at least one face of the band and maintaining the advancing assembly under pressure with a tacky adhesive between the paper and the honeycomb material, to stick them together. The adhesive is applied to the honeycomb material, and the step of advancing the assembly under pressure is begun with the moisture content of the paper substantially less than that of the honeycomb material. As shown, honeycomb material 1 is expanded between curved guide fences (one shown at 3), is coated with adhesive by rollers 5 and 6, and has webs of paper applied to it by rollers 7 and 8. These webs are dried by heaters 14 and 15 or 16 and 17 or both, and the assembly is cooled between belts 11 and 12. If only one side of the honeycomb is to be covered, one paper web is omitted and the adhesive-applying roll on that side moved out of its operating position. The machine may be driven solely by the bands 11 and 12, but it is preferred to drive also rollers 5, 6, 7 and 8. The paper to be applied may have an outer layer of metal foil; in this case the heaters 16 and 17 are not used. The adhesive may be an aqueous dispersion of polyvinyl acetate. Slices of structural honeycomb material may be secured together to form long lengths before being laminated.
