Abstract: 592,305. Magnetrons. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 27, 1944, No. 14403. Convention date, April 24, 1941. [Class 39 (i)] The anode structure of a magnetron oscillator comprises a strip or ribbon 3, Fig. 2, of metal bent into the form of a spiral and extending circumferentially about the cathode 2 for a distance of more than a single turn. The end portions only of the anode may overlap, Fig. 1 (not shown), or the anode spiral 3 may comprise a plurality of turns, Fig. 2. The anode 3 is dimensioned so that its natural circumferential frequency when oscillating in a half-wave mode is equal to the electron oscillation frequency or to a harmonic thereof. The output may be .taken off directly or by induction. In the arrangement shown in Fig. 2, two conductors 8 approximately #/4 in length are connected to the anode 3 and are bridged by a byepass condenser 9 comprising a pair of spaced loops which are slidable on the conductors 8 so as to vary the resonant frequency of the anode. The conductors 8 are coupled to a transmission line 7 leading to an antenna 4. The anode structure may comprise two or more overlapping pieces.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/48
Filed: 1962-04-17
Abstract: 941,761. Hydraulic shock absorbers. FORD MOTOR CO. Ltd. April 17, 1962 [April 27, 1961], No. 14932/62. Heading F2S. A direct-acting telescopic shock absorber, which provides stiffer resistance to extreme deflection in either direction due, e.g., to increased load on rough roads, comprises a valve assembly 38 which works in a pressure tube 18 and has a rod 22 with a bore 40 which telescopically receives a metering rod 32 provided with a reduced midsection 62 joined by upper and lower tapers 68, 70 and which co-operates with a metering disc 18 located by a snap ring 59 within a nut 57 on the valve assembly, and a rubber stop-cup 88 which is supported, with a small clearance, around the metering rod 32 and the rim of which is adapted to make sealing contact with the depending periphery of the piston body 48 after the piston has descended beyond a normal amount. A reservoir 21, between the pressure tube 18 and an outer tube 12, communicates with a compression chamber 46 through recuperative openings 82 in a foot valve 30 controlled by a spring-loaded valve plate 80 and through an axial bore 72 in the metering rod 32 which, with a retainer 78 for a compression spring 90 which supports the cup 88, is secured to the foot valve 30, the bore 72 being provided with a compression orifice 74. Compression ports 50 in the valve body 57 are controlled by a spring-pressed valve plate 56 a radial hole 60 joining a rebound pressure chamber 42 with the bore 40. Over the central region of shock absorber travel since the clearance between the narrower central part of the metering rod 32 and the metering disc 58 is greater than that of the hole 60 the latter controls the rebound force. Near the end of the rebound stroke the reduced clearance between the tapered piston 68 of the metering rod 32 and the metering disc 58 creates a force which is high enough to result in an hydraulic lock. The latter can take the place of the usual rubber bumpers in a suspension system. During a compression stroke most of the fluid passes through the ports 50 in the piston assembly 38 the differential volume of fluid being forced through a compression orifice 74 in the bore 72 and into the reservoir space 76 beneath the foot valve 30. When the piston assembly 38 contacts the cup 88, which is located below the orifice 74, the only fluid outlet from the compression chamber 46 is through the annular space between the cup 88 and the metering rod 32 which space gradually decreases due to the lower tapered portion 70 so that the pressure in chamber 46 progressively rises. The cup 88 has fluid-flow passages in its outer surface.

Filed: 1924-06-20
Abstract: 218,282. Western Electric Co., Ltd., (Assignees of Mathes, R. C.). June 30, 1923, [Convention date]. Secret signalling systems; thermionic modulation systems.-Speech or other band frequencies are divided into a plurality of sub-bands, some or all of which, are inverted and are simultaneously impressed on the carrier wave. The Figure shows filters F<1> - - F<3> separating speech frequencies from the microphone circuit 11 into three sub-bands, which are inverted by modulators M<1>, M<3> by impressing on them frequencies from sources 15, 20, 22 equal in each case to the sum of the edge frequencies of the sub-band, and passing only the lower side band of the resultant by filters F<1> - - F3 to the balanced transmitting modulator TM. The antenna TA is preferably sharply tuned to discriminate in favour of one side band, but if a very high frequency carrier is employed other means of securing single side-band transmission may be employed. At the receiver, the carrier frequency is re-inserted, and the sub-bands are again separated and inverted as at the transmitting station and the combined resultant is applied to the receiver.

[Also in Group XI] A combustion chamber comprising a flame tube located in an air casing, in which the primary air is led through a jacket, into which the fuel is injected surrounding the upstream part. of the flame tube, to the primary combustion zone and the remainder is led into the flame tube as secondary air downstream of the primary combustion zone, has valve means for varying the rotative proportions of the primary and secondary air. The combustion chamber shown comprises a cylindrical flame tube 1 surrounded at its upstream end by a jacket 2 and a casing 6. Combustion air from a duct 8 is led through an annular duct 10 to an annular space 7. Part of the air flows upstream from the space 7 inside the envelope where fuel is supplied by jets 14 and then through the passages 5 into an axial entry 15 of the flame tube. At the entry 15 the mixture of air and fuel vapour is throttled by a disc valve 19 which may be automatically operated by electrical, hydraulic or mechanical means partly or wholly responsive to movements of the engine throttle or to some other factor affected by the main fuel supply, e.g. exhaust jet pipe temperature. Vanes 13 give swirl to the air entering the envelope 2. Apertures 17, some or all of which may be masked by a sliding tube, allow additional air to enter the flame tube 1. The fuel and air mixture may be throttled by means of restricting orifices which are opened or closed by the differential expansion between the flame tube 1 and outer casing 6. The combustion chamber may be lit by injecting fuel through a pilot jet in the vicinity of the sparking-plug 16.
