Title: Improvements in or relating to telephone systems
IPC: H04M1/58
Filed: 1919-04-23
Abstract: 153,167. Lenaghan, T. April 23, 1919. Telephonic systems.-The elements T<1>, T<2> of a double-capsule transmitter are connected in parallel with primary windings P<1>, P<2>, the corresponding secondaries S', S<2> being in parallel in the line circuit. Owing to the impedance of the secondaries S<1>, S<2>, incoming currents follow the circuit indicated by the wavy arrows, passing through the capsules in series to the electro-magnetic receiver R. As the increase in resistance of one capsule compensates the decrease of resistance in the other, the receiver R is not affected by the outgoing currents. The current fluctuations are confined to a local circuit, including the primaries P<1>, P<2>, which act inductivelv on the line circuit.

Title: Improvements in agricultural implements mounted on wheels adapted to run on definite tracks
IPC: A01B69/00
Filed: 1921-10-11
Abstract: 191,460. Tompkins, G. Oct. 11, 1921. Power cultivation; travelling and propelling gear; indicators and alarms.-To ensure the wheels of a frame carrying agricultural tools remaining on tracks which extend across the ground to be treated, devices are provided which either indicate when a wheel is directed at an angle to the line of draft or which automatically redirect the wheel in the proper direction. The tracks or runways 1, which may be of wood, gravel, concrete, stone or metal, are placed at predetermined distances apart through the field to be worked, either singly or in pairs. The frame 2, carrying the tools 3, is mounted on plates 9 having ball races in which anti-friction balls on frames 4 run. A pair of brackets 5 depends from each frame 4 and has mounted therein an axle 6 carrying s wheel 7 running on the track 1. Wheels 13 carried by brackets 12 from the frame 2 may be provided to engage the sides of the tracks. To redirect the wheels 7 in proper direction should they tend to move off the track, a device such as that shown in Fig. 5 is employed. The ends of the axle 6 are provided with clutch teeth adapted on lateral movement of the wheel to engage similar teeth on a clutch member 26; the member 26 carries keys 27 which when moved laterally engage in grooves in a stub shaft 25 which drives, through bevel-gear 31, 30 and a shaft 29, a pinion 32 which engages a rack 33 on a bracket 34 depending from the plate 9. When the wheel 7 moves to one or other side of the track 1, the shaft 29 is operated and the frame 4 turned to direct the wheel to the middle of the track again. In the modification shown in Fig. 7, the lateral movement of the axle operates a lever 35 completing the circuit of an electric bell, thus giving an audible warning and permitting the attendant to redirect the wheel by hand. In another modification, a visual signal is operated. Similar devices may be used with the side-wheels 13, or these may be provided with cushioning-springs. The tracks may be circular, in which case a post, inserted in a sleeve member let into the ground at the centre of the circle, is connected to the frame carrying the implements through a swivel. Braces are fitted to strengthen the frame, and one or two trackways for the supporting wheels are provided. When two tracks are provided, a pathway for draught animals may be arranged between them. The frame may carry ploughs, cultivators, seed-sowing or planting devices or spraying, cutting, harvesting or carrying machinery or containers for liquid or powder to be distributed. The frame may be drawn by animals or a tractor, or may be propelled by mechanical power, cogs being provided on the tracks to receive the thrust of the power.
Patent GB-269555-A (GB)
Abstract: 269,555. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger, R. H.). April 13, 1926, [Convention date]. Copying-telegraphs.-Sharper detail in the reproduced picture is obtained by the use of arrangements for increasing the rapidity of response of the transmitting relays when the rate of change of light intensity in the original is very rapid. The invention is particularly applicable to the system described in Specifications 230,075 and 237,263. Fig. 1 shows amplifying valves 4, 10 employed in series between the photo-electric cell 1 and the transmitting relays. The cell circuit is coupled by a resistance 3 to the input circuit of the valve 4, and the output circuit, of the valve 4 includes a resistance 6 Which is shunted by a condenser 8 and is in series with a resistance 7 in the input circuit of the valve 10. The arrangement is such that the fall of potential in the output circuit of the valve 4 due to the resistance 6 is not transferred to the input circuit of the valve 10 unless the changes in the light intensity incident on the cell 1 are so rapid as to transmit pulses of current through the condenser 8. Fig. 2 shows a modified arrangement. The output circuit of the valve 4 is coupled by a resistance 7 to the input circuit of the valve 10 which includes a condenser 11 shunted by a resistance 12, a bias battery 13, and a resistance 14 in series. In this arrangement a rapid change in the intensity of light incident on the cell 1 causes a pulse of current to pass through the condenser 11 direct to the grid of the valve 10. The modifications required in the circuit arrangements of the system described with reference to Fig. 1 of Specification 237,263, to enable that system to operate according to the present invention, are described.

The first-mentioned set of tongues actually snap into place to retain the elements whilst the remaining set act as positioning stops. The centre section of the bracket, formed where the rectangle C, D, E, F is cut from the material before shaping may be curved outwardly as shown to receive a supporting cross-arm. A slightly modified bracket with curved cross-webs and no positioning stops is described with reference to Figs. 3 and 4 (both not shown). The bracket may be formed in metal for parasitic elements or in insulating material to carry centre-fed dipole elements.
