Title: Improvements in or relating to transmission systems for radio waves
IPC: H01Q15/02
Filed: 1947-01-02
Abstract: 655,936. Wave-guides, directive radio systems. WESTERN ELECTRIC CO., Inc. Jan. 2, 1947, No. 160. Convention date, Jan. 22, 1946. [Class 40 (vii)] [Also in Group XL (b)] A device for refracting or for modifying the polarization of guided or unguided electromagnetic waves comprises a plurality of parallel conductive plates spaced apart by at least a half-wavelength at the frequency for which the device is designed. A device, Fig. 1, for converting plane-polarized waves into circularly polarized waves, comprises a plurality of plates 3 which are spaced apart a distance a and have a depth d such that the phase velocity of waves polarized parallel to the plates is so increased that the relative phase of such waves is altered by 90 degrees, or an odd multiple thereof, with respect to the waves polarized perpendicularly to the direction of the plates. The plane-polarized incident wave is arranged with its plane of polarization at 45 degrees to the direction of the plates and the components perpendicular and parallel to the plates emerge from the device with a phase difference of 90 degrees so that a circularlypolarized wave results. A device for altering the plane of polarization of plane-polarized waves is similar to that shown in Fig. 1, but with the dimension d twice as large. The phase difference between the emergent components is consequently 180 degrees, and with components of equal amplitude the plane of polarization is turned through 90 degrees. Fig. 6 shows a refracting prism which, since it has a refractive index of less than unity, refracts waves towards its apex. The prism illustrated is not isotropic since it does not refract waves of all polarizations ; it may, however, be made isotropic by introducing plates perpendicular to those shown, thereby resulting in a prism of cellular construction. Construction. The devices shown in Figs. 1 and 6 comprise dielectric channels open on two sides and mounted in a wooden insulating frame. They may alternatively be mounted in a metal frame which results in all sides of each channel being closed. In an alternative arrangement the plates are supported in a solid dielectric, such as polystyrene foam having a dielectric constant close to unity. Minimizing reflection from surfaces. The edges of the plates used in Figs. 1 and 6 may be castellated as shown in Fig. 8 to prevent reflection both of incident and emergent waves. In an alternative construction, Fig. 10 (not shown), V-shaped recesses, half a wavelength deep and half a wavelength wide are formed in the edges of the plates. In Fig. 11 (not shown), alternate plates stand out a quarter wavelength from the plates adjacent thereto and in Fig. 12 (not shown), to each plate, which is made of a thick material, there is attached a thin strip a quarter wavelength wide.

Abstract: 551,683. Hydraulic intensifiers; fluid-pressure engines. BRISTOL AEROPLANE CO., Ltd., and PONTING, R. Jan. 5, 1939, No. 450. [Class 69ii)] An apparatus for increasing or decreasing fluid pressure which may be used for boosting the pressure of liquid in a hydraulic power transmission system comprises two or more motor pistons 10, 11 ; 71, 72 mechanically connected to pump-plungers 16, 17 ; 73, 74, with a control valve for the cylinder of each motor piston, and an operative connection between each motor piston and the control valve of another motor-piston so that one motor piston is set in motion when another motor piston reaches the end of its stroke. The pistons 10, 11 ; 71, 72 are connected together and each piston is integral with a pumpplunger which is of smaller diameter when the pressure of oil entering a supply pipe 48 is to be increased, or vice versa. Piston valves 35, 65 are actuated with lost motion by levers 56, 70 operated by contact with the ends of the pistons when they reach the ends of their stroke in either direction, and the operation is such that after the oil has been admitted to the left end of the cylinder 71a via pipe 51 and valve 35, the valve 65 is moved to the right to connect the oil to the right end of the cylinder 12 and the pistons 10, 11 are moved towards the left until the valve 35 is operated to connect the inlet pipe 48 to the right end of cylinder 72a. 'Each time a piston is operated one of the pumps forces the oil under increased pressure into the outlet pipe 28. In a modification one double-acting piston replaces each pair of pistons 10, 11 and the pump plungers are formed by integral extensions from the pistons. The valves are formed as sleeve-like members surrounding the piston rods and actuated by enlargements of the rod.

Abstract: 320,293. Villeminot, J. Jan. 7, 1929. Four-stroke-cycle engines.-In an engine having an auxiliary piston 9 and a sleeve valve 10, both operated from a half-speed shaft 25, the auxiliary piston is so actuated that its descending movement is more rapid than its ascending movement. The sleeve ports 23, 24 are arranged to be covered by the auxiliary piston during combustion, and the sleeve valve is given a reciprocating motion of the same frequency as that of the auxiliary piston, but with a certain amount of advance and a longer stroke. The shaft 25 is offset from the centre line of the cylinder, for example to a distance equal to one-half of its crank arm, so as to give the quicker down-stroke of the auxiliary piston. On the contrary, the sleeve valve is given a quicker up-stroke than down-stroke by means of a link 16 connected to the auxiliary piston rod 14 and to a lever 28, which is fulcrumed at 30 and connected by a link 33 to the valve. The sleeve-valve ports 23, 24 control respectively exhaust at 13 and inlet at 12. In a modification, the link 16 is connected directly to the sleeve valve, which has a single port controlling inlet and exhaust ports at the same side of the cylinder.

Abstract: 613,442. Electricity supply. SANGAMO WESTON, Ltd. Jan. 8, 1946, No. 735. Convention date, Jan. 20, 1945. [Class 38 (iv)] Running generators in parallel.-A control system for a pair of parallel connected A.C. generators operates, upon substantial departure from equality of load division, to disconnect a part of the load, or if this is ineffective to restore the balance of load between the machines, to disconnect subsequently one machine, notwithstanding possible resultant overloading of the other machine. Generators 2 and 3 supplying bus-bars 1, also energize the opposed primary windings of a transformer 4, the secondary of which is connected to opposite terminals of a " modulator " bridge-rectifier 5 and carries no current when the loads on the machines are equal. A transformer 6 connected to the other opposite terminals of the rectifier 5, is supplied from the bus-bars through contacts of a relay 13 energized by generator 3. Failure of one machine, for example generator 2, to carry its share of the load, effects the energization of the secondary circuit of transformer 4 and the operating circuit of a D.C. relay 8, the movable contact 10 of which completes a D.C. circuit from source 14, through contact 11, for relays 16 and 18. The former opens its contacts to disconnect load 17 and if this is ineffective to restore the desired balance between the two machines, the contacts of relay 18, which is slow-acting, subsequently open to disconnect the generator 2.
