Title: Improvements in or relating to modulator circuit arrangements for high-frequency electrical signalling
IPC: H03C1/20
Filed: 1938-04-22
Abstract: 515,047. Modulation systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and CLOUGH, N. H. April 22, 1938, No. 12156. [Class 40 (v)] A modulator system comprises two class-C high-frequency stages in series, with four class-B modulator valves so connected as to constitute alternative paths from the D.C. source to each stage, two of the modulator valves operating to secure modulation for positive half-waves, and the other two operating for negative half-waves: The two highfrequency stages HF1, HF2 are connected in series with the modulation frequency choke CH across the high-tension supply. The modulator valves V1, V2 are each connected across the choke CH, and one high-frequency stage and the modulator valves V1<1> V2<1>, are each connected across one high-frequency stage. Valves V1 and V2 are arranged to be simultaneously conducting on one modulation halfcycle and valves V1<1> and V2<1> on the other halfcycle. The grids of V1 and V2<1> are fed in phase-opposition from points IT1, IT2 on the secondary S of the modulation input-transformer T. The grids of V1<1> and V2 are fed with layeramplitude voltages from the extremities of secondary S due to the fact that their cathodeearth potentials are varying at modulation frequency. In a modification, Fig. 3 (not shown) the grids of VI and V2<1> are driven from a modulation transformer, while the modulation voltages for the grids of V1<1> and V2 are obtained from tappings on the choke CH. In a modification of this, Fig. 4 (not shown) the voltages supplied to the grids of V1<1> and V2 from the choke CH are adjustable by means of potentiometers. In a preferred modification, Fig. 5 (not shown), the modulation input is applied to sub-sub-modulator valves which feed valves V1 and V2<1>, and also sub-modulator valves which feed the grids of V1<1> and V2. The outputs of the two high-frequency stages may be combined in a single circuit; or, where the same modulation is required to be transmitted on two different wavelengths simultaneously, two high-frequency stages may operate on different wavelengths with individual output circuits.

Title: An improved clutch for use more especially in the transmission of power in motor boats
IPC: F16D23/04
Filed: 1930-04-17
Abstract: 350,143. Clutches for conveying rotary motion. DUMBELL, J. B. and DUMBELL, P. B., of Wulfruna Works, Lever Street, Wolverhampton. April 17., 1930, No. 12162. [Class 80 (ii).] In a combined clutch more particularly for the transmission system of screw propeller driving mechanism wherein there is a first-intention friction clutch and a positive clutch element, the arrangement is characterized in that after the friction clutch has been engaged the positive clutch is subsequently engaged by endwise movement of the driven member under the action of the drive. The driven member may be held from endwise movement by a retaining device which is releasable either by hand or automatically. The driving shaft A carries one member E of a friction clutch and an extension C on the driven member B supports the other member d, D. The part E is provided with a number of forwardly projecting dogs e, and the forward extension C has at its forward end a number of dogs c. The engagement of the friction clutch is controlled by a hand-lever F and the action of the dog clutch is controlled by a. spring-pressed detent K. When the friction clutch is moved into engagement and the drive is taken up, the thrust of the propeller on the shaft B rises until at a definite time the catch detent is forced aside and the dogs take up the positive drive. Both clutches are disengagable by the lever F, the part D contacting with the shoulder C<SP>2> for moving the dogs c rearwardly. For hand control lever M, Fig. 3, is provided whereby the detent K may be raised clear of the collar C1 on the sleeve C. Instead of a detent, spring-pressed balls acting on a curved collar on the sleeve may be used.

Patent GB-201264-A (GB)
Title: Improvements in antenna systems for wireless communications
IPC: H01Q1/52
Filed: 1922-05-05
Abstract: 201,264. Robinson, E. Y. May 5, 1922. Aerials.-The masts of wireless antennµ are made in insulated segments, and are electrically graded so that the potential drop is more or less uniform from aerial to earth. This avoids the insulation difficulties which exist in the ordinarv method of aerial suspension and also prevents energy losses due to stray currents induced in the mast or other metallic supports. The supporting-guys for the masts are similarly segmented and graded electrically. The grading may be uniform, or it may be arranged to coincide with the electrostatic stress-distribution normally present between the antennµ and earth. The varying potentials of the different segments are secured by suitably proportioning the dimensions of each section so that its capacity coupling across the insulation to the adjacent section gives the desired distribution. Or actual condensers may be connected across each segment to the antennµ, to earth, and to adjacent segments. Fig. 5 is a schematic diagram of the capacity couplings of such an arrangement, where 1 indicates the aerial, 1C1 - - 1C8 represents the couplings between the various segments, 2C2 - - 2C8 the couplings between segments and aerial, and 3C2 - - 3C8 those between segments and earth. Alternatively each segment is fed with high-frequency power in phase with the voltage on the aerial, as shown in Fig. 6. Signalling energy is fed to the aerial through a transformer 14, 15 and downlead 2, whilst tappings from a transformer 16 fed from the same, source of supply are led to the various segments 7. This method may be combined with the electrostatic couplings previously described. Fig. 8 illustrates an arrangement of supporting-guys for the mast, each being divided into insulated sections and graded so that the potentials of the ends nearest the mast correspond with that of the particular mast-segment to which it is secured. The grading of the mast is preferably such that the uppermost segment carries the antennµ without insulation; or there may be a certain potential drop for which relatively light insulation is sufficient. Suitable flashover devices, such as arcing horns, may be provided between the various segments, to protect the insulation. When the mast is guyed, the segments are preferably pin-jointed together, as shown in Fig. 7, to avoid shearing stresses on the insulators. The insulator 23 is secured between two metal plates 26, 27 with an interposed laver of lead or a lead allov and interlocked as shown at 28. The combination forms a coupling condenser. A large rain-shed 24 is provided and is corrugated beneath at 25, in order to increase the length of the leakage path. The 'bottom of the upper mast segment 22 rests upon a curved surface 29, allowing a certain degree of freedom limited by the engagement of a pin 30 with a recess 31. It is stated that such aerials may be used for the wireless transmission of power.
