Title: Electro-magnetic horn radiators
IPC: H01Q21/06
Filed: 1941-08-29
Abstract: 551,585. Wireless signalling; aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 29, 1941, No. 11091. Convention date, Aug. 31, 1940. [Class 40 (v)] Relates to electromagnetic horn radiators in which energy is supplied from a transmission line in phase to a plurality of tapered horns each associated with a section of wave guide within which is an antenna. Fig. 2 shows four horns with their mouths in the same plane, the throat ends of the horns being associated with wave-guides 12 fed in phase by a transmission line TL. A small overall length may be obtained by constructing the horn as shown in Figs. 3, 4, 5 and 6 respectively. A grid 34, Fig. 3, of horizontal wires at right angles to the electric field component of the desired wave cuts out components, parallel to the grid, of other types of waves, which may be produced by the valve generator or by reflection from the curved surfaces of the horn. A-smaller grid may be placed at the throat. The horn may be tapered in one or both directions. With the arrangement shown in Fig. 6, undesired waves generated by reflection from the horn combine in opposing phase relationship as they emerge from the horn and so cancel one another. The horn may have a rate of flare which is initially large but decreases towards the mouth, Fig. 7 (not shown) or, in order to reduce reflection at the junction with the wave-guide section 12, Fig. 8, the horn may be formed with an increasing rate of flare near the throat, as at 86, and a decreasing rate of flare near the mouth, as at 76. The short waveguide section 12 may be replaced by a waveguide or pipe line 92, Fig. 9, several wavelengths long and in order to prevent reflection at the load end of the line, a branch section 94 closed by a metal sheet 95 is connected to the guide near its junction with the horn. A similar arrangement may be used with a curved horn, Fig. 10 (not shown).

Abstract: 1,174,421. Applying travellers to rings of spinning frames. EADIE BROS. & CO. Ltd. 14 June, 1967 [15 March, 1966], No. 11199/66. Heading D1F. A traveller applying tool stretches the traveller so that it does not damage the ring when being applied. The tool has a fixed plate A carrying a magazine E whose end terminates a distance a<SP>4</SP> from the plate A sufficient for passage of a traveller T. The plate A also carries a handle b having an applying head C with a spring loaded pin C<SP>1</SP> which passes through an arcuate slot a<SP>4</SP> in the plate A to abut the magazine E. In use the plate A is placed over the ring R so that a traveller T falls by gravity into the gap a<SP>4</SP> and loops over the pin c<SP>1</SP>. The handle b is then operated for the pin c<SP>1</SP> to move along slot a<SP>1</SP> to stretch the traveller over the ring as shown in Fig. 8B. A cam on the plate A finally causes the pin c<SP>1</SP> to retract from the gap a<SP>4</SP> so that the traveller may spring over the ring.

Abstract: 293,509. Pinder, G. April 27, 1927. Games of skill.-Apparatus for playing a game comprises a series of independently rotatable rings 12, Figs. 1 and 2, each subdivided into a number of differently coloured parts and provided with radial projections 13 adapted to be engaged for locking purposes by one of a series of stops 27 depending from an axially slidable rod 25. Each ring is supported on a disc 10 that is connected through a free-wheel device to a sleeve 8 freely mounted on a fixed vertical spindle 4. A toothed sector 15 meshing with a pinion 14 on the sleeve, 8 is adapted to be rotated against the action of a spring 23 by the engagement with an arm 18, on the sector, of a pin 19 projecting from a rotatable shaft 21 having a handle 22. Upon the insertion of a coin, the rod 25 moves outwardly under the action of a spring 28 thereby releasing the rings 12 which are caused to rotate by the return of the sector 15 to its original position. The operator endeavours, by pressing in the rod 25, to stop the rings in such a position that similarly coloured parts of the rings are adjacent. In a modification, Fig. 7, the pinion 14 is replaced by a sprocket wheel 32. A chain 33, anchored at one end to a spring 34 and connected at the other to a slide bar 35 engages the wheel 32. The spring 34 is tensioned by a pivoted handle 37 engaging the end 39 of the slide 35. The handle is guided in a cam-slot in such a manner that, at the end of the tensioning movement, the slide is released and the sleeve 8 is rotated under the action of the spring.

Abstract: 1,011,244. Magnetrons; travelling wave tubes. GENERAL ELECTRIC CO. March 23, 1962 [March 24, 1961], No. 11297/62. Heading H1D. A travelling wave magnetron comprises a cathode 17, a periodic slow wave anode structure 16 surrounding the cathode supporting a travelling wave, a single waveguide or coaxial transmission line 28 concentric with the anode structure and connected to forward or output coupling means 31 at one end thereof and either connected to a similar coupling means 31 at the other end for the introduction of control signals or terminated at the other end by attenuating means, and directional coupling means comprising a plurality of coupling connections, as shown slots 36, equally spaced completely about the anode structure and connecting each periodic section thereof with the transmission line or waveguide and acting as directional couplers. The resonant cavities may be defined by vanes 15 with enlarged inner ends or multislotted or interdigitated structures may be used. The directional coupling means may be inductive loops, probes or conductive pins instead of slots. The device may be operated as an amplifier, locked oscillator, frequency coherer, mode shipper, duplexer or reflection dissipator. A loss coating of high resistance material may be used at one end of the structure, Fig. 7 (not shown) to act as attenuating means. The coaxial transmission line may surround the anode or its outer conductor may be integral with one end space of the device. In the former case the coaxial line is inside or outside the main tube wall. The inner conductor of the coaxial line is an annulus supported at intervals by annular insulators. To achieve directional coupling, the number of coupling slots times the phase-shift between adjacent slots equals an integral number of wavelengths. The number of slots may be equal to or a submultiple of the number of resonators and the phase displacement between the slots other than an integral number of half wavelengths.

Abstract: In a process for the dry or substantially dry polymerization of olefines utilizing a mass of polyolefine as carrier for a Ziegler type catalyst, each catalyst component is conveyed as a stream, mist or vapour and each stream is brought into contact with the stirred mass of polyolefine whereby the catalyst is formed thereon.  The Specification defines substantially dry as less than 1 litre of solvent per kilogram of polyolefine produced, and illustrates the polymerization of ethylene with titanium chloride + aluminium triethyl or monochlorodiethyl aluminium as catalyst components, and wherein hexane or benzine may be used as diluent. Nitrogen, methane or ethylene may be used as carrier gases for the catalyst components, and the method of addition by spraying of catalyst component solution into the reaction vessel is also described.ALSO:A process comprises the dry or substantially dry polymerization of olefines utilizing a mass of polyolefine as carrier for a Ziegler type catalyst complex, wherein each catalyst component, or solution thereof, is conveyed as a separate stream of gas, mist or vapour and each stream is brought into contact with the stirred mass of polyolefine, the catalyst complex being formed thereon. The Specification defines substantially dry as less than 1 litre of solvent per kilogram of polyolefine produced, and illustrates the polymerization of ethylene with titanium chloride and aluminium triethyl or monochloro diethyl aluminium as catalyst components, and wherein hexane or benzine may be used as diluent. Methods disclosed for bringing the catalyst components into contact with the carrier are, (1) the use of a stream of inert gas such as nitrogen or methane, (2) the use of a stream of ethylene as carrier gas for one catalyst component, and (3) the addition of catalyst component solution by spraying through a nozzle. Formation of catalyst may be in the same or in a different vessel from that used in the polymerization, and the polyolefine carrier utilized may be separately produced in a previous polymerization or may be obtained by polymerization in the presence of diluents which are subsequently removed following which the process of the invention is then carried out.  The invention enables the amount of catalyst used to be easily controlled, particularly in continuous processes, and effects the production of more uniform products even with less catalyst.  In the examples ethylene is added continuously during the polymerization.

Title: Process and apparatus for hermetically closing vessels containing gases at a pressure exceeding one atmosphere
IPC: H01J9/40
Filed: 1938-04-22
Abstract: 508,615. Welding glass. EGYESULT IZZOLAMPA ES VILLAMOSSAGI, R. T. April 22, 1938, No. 12095. Convention date, April 22, 1937. [Class 56] [Also in Group XI] In a process for hermetically sealing gas-filled vessels, such as electric lamps, provided with an evacuating and filling tube 1 made of glass or glasslike material and containing a gas filling at a pressure exceeding one atmossphere, the glass tube, prior to closure, is softened by heating and, at least during the sealing-off operation, is surrounded by a flowing gas, e.g. air, under a pressure which is at least equal to, but is preferably greater than the internal gas pressure within the vessel. The compression of the softened glass tube to effect sealing may be produced entirely by the superatmospheric pressure exerted by the flowing gas, or tools may be used for compressing the tube, for example the tools and glass tube may be surrounded by a chamber which does not have to be gas-tight, and the compressed air flowing through the chamber may be used for accelerating the cooling after sealing and even for operating the tools. The tube may be heated by radiant heat from an electric heating device, or a gas flame such as a hydrogen flame may be used. If the arrangement is such that the air admitted to the chamber is'under a pressure only slightly in excess of one atmosphere the requisite chamber pressure may be developed by the burning of the gas-flame, the chamber preferably being water-cooled to prevent overheating. The flames may be stabilised by placing in their path a continuously incandescing body, e.g. a ceramic body or an electrically heated metal body. Alternatively, the gas flames may be fed from a source which is a multiple of the pressure required to maintain them with certainty and may be a multiple of the pressure required within the vessel. In the example, the portion of the tube 1 that is to be sealed is surrounded by an electric resistance heater within a vessel 3. Compressed air is admitted through a pipe connection 4 and escapes through openings 5 between the tube 1 and adjacent parts of the vessel. The vessel may be made in two parts which close around the tube 1, the heater 2 then being in two semi-cylindrical parts which are brought together into a substantially complete cylinder.
