Title: Improvements in and relating to methods of and means for signalling in wireless telegraphy
IPC: H04L27/04
Filed: 1922-06-14
Abstract: 203,788. Preston, L. G., Shearing, G., and Grainger, E. J. June 14, 1922. Thermionic generators and modulating systems. -In a thermionic generator set, comprising a number of valves in parallel fed from a common high-tension supply or from separate sources, and provided with separate grid leaks, the signalling key produces a potential change in the grid-filament circuit which is effective in reducing the aerial oscillations to zero without actually breaking the grid circuit, the grid of each valve meanwhile acquiring the most suitable mean negative potential for efficient working. As shown in Fig. 1 the valves C - - G are fed in parallel from a common high-tension source through a choke A. A rectifier X supplies current to a resistance r. and the signalling-key Z applies the potential drop across the resistance to the grid of the valves. When the key is in contact with the point b, the potential of the grid is made slightly negative with respect to the filaments and the aerial T radiates continuous oscillations. When the key Z is thrown over to the contact point a, the grids become decidedly negative and oscillation ceases. The grid circuits, each having a separate grid leak H - - P, are coupled in common to the aerial circuit through the coils Q, S. A high resistance r<1> shunted by a condenser k prevents sparking across the contents a, b. Fig. 2 shows a similar keying-arrangement applied to a transmitting-set in which the plates of the valves C, D, E are fed from a threephase generator, the mid-point of which is - earthed. An alternative keying arrangement is also described on which the filament and anode of a three-electrode valve are shunted across the condenser U of Figs. 1 and 2. The switch is arranged to connect both the grid and filament to the tapping point b for normal oscillation, whilst the grid is connected to the tapping point a and the filament to a point on the resistance r of slightly less negative potential for reducing the aerial oscillations to zero. The key Z can be operated at high speeds by electrical control from an automatic transmitter.

Title: Improvements in dobbies or shedding mechanism of looms for weaving
IPC: D03C1/22
Filed: 1927-06-22
Abstract: 295,474. Ward, J. June 22, 1927. Loom dobbies.-The feeder levers of a double lift dobby have curved-extensions c<3> acted upon initially by the side faces of the lattice pegs e, which afterwards lift the levers. When the pattern barrel again rotates, the pegs clear the levers, which are then free to fall and be engaged by the succeeding rows of pegs. As applied to cross border dobbies with two or more cylinders, the feeders are acted upon by supplementary pattern controlled bell crank levers as shown or have two or more surfaces arranged to be acted upon by the side surfaces of the pegs of two or more cylinders.

IPC: B65G47/31
Filed: 1971-05-24
Abstract: 1305361 Handling bars and tubes on endless roller conveyers MORGAN CONSTRUCTIONCO 24 May 1971 [17 June 1970] 16561/71 Heading B8A Means for causing progressive separation of side-by-side substantially-straight elongate elements 14, comprises a conveyer 4 for feeding the elements to a first set of tapered rollers 16, all of which taper from their small ends to their large ends, the small ends of the rollers being aligned and adjacent the conveyer, the axes of the rollers extending obliquely relative to the axes of the elements 14. The conveyer 4 is driven, and the elements are successively delivered from the conveyer to rest on the rollers near the small ends of the latter. The surface speed at the small ends of the rollers 16 is approximately that of the delivery speed of the conveyer. This causes continuous horizontal acceleration of each element after delivery to the rollers by the conveyer while maintaining the elements in parallelism, and the elements are increasingly separated as they move across the tapered rolls 16 from the small to the large ends. Each element 14 is fed by the rolls 16 to a shoot 28 having a series of notches 26 in which the element is retained until discharged by a member 32. The latter, when in its discharge position (broken lines), acts as a stop to movement of further elements. A photo-electric counter 34 may control the delivery of the elements. The elements 14 may be gripped between each roller 16 and an auxiliary tapered roller (Fig. 6, not shown) to provide increased adhesion with the elements 14. Instead of a tapered auxiliary roller there may be a cylindrical roller formed from a series of side-byside freely rotatable cylindrical elements (Fig. 7, not shown). Rollers may be used in series to provide an increased degree of separation and acceleration (Fig. 4, not shown). Rollers may be used in series and arranged in the sense to provide acceleration under the first roller and deceleration under the second roller (Fig. 8, not shown). There may be an endless conveyer between the two rollers (Fig. 9, not shown). The two rollers may be arranged so that sideways movement produced under the first roller, is counteracted by sideways movement in an opposite sense under the second roller, so as to bring the elements back to their original alignment. In a single stage of acceleration, two rollers may be arranged side by side but with their small ends adjacent (Fig. 5, not shown) so that any tendency to sideways movement of the elements is cancelled out.

[Class 7 (ii).] In the cowling 4 of an aircraft engine a stream of cooling air passing over the cylinder heads and exhaust pipes is isolated from the main cooling stream flowing over the cylinders. A radial-cylinder engine is shown in which the main air enters through the space between an annular shell 13 and a nose 7 which are secured to the crank-case by tubular stays 18 and on annular tube 16. The shell 13, carrying a grid 14 and a conical guide 53, directs additional air on to the upper cylinder barrels which are obscured by the gear-box. The partition, isolating the air flowing over the exhaust manifold 37, comprises plates 21, 23A, 42 fixed to the head and to the ring 16. The air enters by ports 45 in the plate 42 which carry cylinder baffles 43 bent round the rear of the cylinders. The air passages are completed by a detachable casing 1 having scoops 6 for the main air flow and upstanding parts 4 and baffles 56, above the rocker boxes, for the air flowing over the exhaust manifold 37. The air flow through the cowling may be controlled by adjustable shutters.
