Class 100(1) A machine for winding a flexible web 4 without the use of a reel, comprises two rollers 9, 10 over which an endless conveyer band 8 passes, means for feeding a web along the conveyer band 8, and a pair of parallel coiling rollers 15, 16 adjacent the conveyer band and extending transversely to the direct i o n of movement thereof, the coiling rollers 15, 16, conveyer band 8, and feeding means being driven so that the peripheral speed of the coiling rollers 15, 16, is less than the speed of the conveyer band 8, but equal to, or greater than, the speed at which the web is fed along the conveyer. The web 8 is fed from a feeding roller 2 to rollers 5, 6 which rotate at a higher speed than the' roller 2 so that the web is kept taut. An arm 13 is spring-urged, such that prongs 11 on the arm engage between narrow bands forming the conveyer band 8 and between grooves in the roller 15. The leading end of the web is deviated by the prongs 11 and the roller 15 into contact with the roller 16 to start the formation of a roll 18. The roller 15 pivots about the axis of the roller 16, while the prongs 11 are pressed rearwardly to accommodate the roll being wound. After a required length of web has been wound, a cutting device 19 cuts the web to initiate the formation of a further roll.

Title: Improvements relating to temperature indicating and control systems
IPC: G01K7/38
Filed: 1945-12-13
Abstract: 605,093. Automatic control systems for gas turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and ALCOCK, J. F. Dec. 13; 1945, Nos. 33834/45 and 32274/46. [Classes 35 and 38 (iv)] In a gas turbine temperature-control system, as the temperature of a thermosensitive ferromagnetic element passes through the Curie point the consequent alteration in magnetic flux causes the operation of devices regulating the supply of heat to the zone adjacent to the element. In the embodiment shown, the thermosensitive element 1 and armature 3 are in parallel across the permanent magnet 8, the circuit being completed by soft-iron bars 7. The armature 3 is pivoted so as to be attracted by poles 7a and is normally urged by spring 4, its, present air-gaps at each end and to close the open end 5 of pipe 9 with the disc 6. The duct 26 supplies the chambers 22, 23 with air from the compressor delivery, the pressure in chamber 23 being maintained at a constant value relative to the supply by the vents 28, 29 communicating with the atmosphere, and subject to a maximum set by relief valve 30. Chambers 22, 23 are separated by diaphragm 11, fitted with flexible portion 51 and supporting rod 32, of piston valve 33. At starting, the compressor pressure is negligible, the control is inoperative and the light biassing spring 36 maintains valve 33 in the full fuel supply position. At speed, with the element 1 at or above the Curie point, the reluctance of the element is raised above the value at normal temperature and the flux density in armature 3 is correspondingly increased, resulting in its rotation towards the pole pieces 7a, thereby opening pipe 9 to the atmosphere and lowering the air pressure in space 22. The pressure in space 23 thereupon operates to depress the diaphragm 11 and to close the fuel valve 33. Cut-off at acceleration is prevented by arranging to provide element 1 with an adequate thermal lag, armature 3 may be balanced against gravity forces and a suitable force-distance characteristic is produced by the shaping of poles 7a. To prevent local over-heating, a number of units may be provided in the duct, all connected to the pipe 9. In a further embodiment (not shown), the fuel supply piston valve is operated by an armature controlled by two opposed A.C. energized solenoids, in series with one of which is a choke coil the impedance of which is varied by a thermosensitive magnetic element. This system may be rendered inoperative at low speeds and may have a modified temperature response, e.g. to permit an increase in temperature with a reduction of engine speed. A wheatstone bridge circuit and thermionic amplification may be incorporated. The invention may also be applied to the control of temperature in gas-turbine heat exchanges employing the exhaust gases as the heating agency. In one form of construction (not shown) the armature is pivoted on ballbearings and two sealing plates are provided between the sensitive element and the magnet which protect the latter from both hot gases and radiant heat.

Title: Process for the production of salts of diaminoketones
IPC: C07D227/00
Filed: 1960-10-03
Abstract: Salts of diaminoketones are prepared by heating at least 2 mols of an anhydrous alkaline earth metal oxide to a temperature of from 250 DEG to 500 DEG C. with a lactam or polyamide of an aminocarboxylic acid in an amount providing the equivalent of approximately 1 mol. of said aminocarboxylic acid, distilling of the volatile fractions comprising intermediate Schiff's bases and either hydrolysing said bases in aqueous mineral acid to form the salts of diaminoketones directly, or treating said bases with hot caustic alkali solution and dissolving the resulting product in aqueous mineral acid to form the diaminoketone salts.  Preferred lactams have 5 to 9 ring members and may be substituted by alkyl, aryl or cycloalkyl groups. Polycaprolactam is specified as a suitable polyamide.  Specified mineral acids are hydrochloric, sulphuric and phosphoric acids.  On treatment with bases, the salts of the diaminoketones give unstable diaminoketones which cyclise to form Schiff's bases.  The latter may also be converted into organic acid salts of diaminoketones by treatment with, for example, acetic, propionic and oxalic acids. Examples describe the preparation of salts of 1,11-diamino-6-undecanone and 1,7-diamino-4-heptanone.

Abstract: 1,217,070. Gas turbine plant and combustion chambers. ROLLS-ROYCE Ltd. July 17, 1968, No.33974/68. Headings F1G and F1L. A gas turbine engine comprises a compressor 14 supplying air to combustion equipment 37 for combustion with fuel at substantially constant volume, a power turbine 84 driven by the combustion products and a further turbine 104 driven by the gases leaving the power turbine and itself driving the compressor 14. Air from the centrifugal compressor 14 enters an annular chamber 30 which has disposed at its downstream end four equi-angularly spaced rotary disc valves 42 each mounted on a respective hollow shaft 44 driven by a shaft 46 and reduction gearing 50, 52 &c. from the compressor shaft 16. Each rotary disc has a port therein to control the flow of air from chamber 30 to the inlet 36 of one of four generally spherical combustion chambers 37 and the flow of combustion products from the outlet 39 to the multi-stage power turbine 84. The latter drives the output shaft 126 of a land vehicle through gearing 114, 116 &c. Gases leaving the power turbine 84 enter an annular plenum chamber 100 and thence drive the further turbine 104 connected to compressor 14 before exhausting at 110. Leakage at the faces 68, 70 of each valve disc 42 is prevented by sealing rings 76, 78 mounted in eccentric grooves in the faces to co-operate with the adjacent stationary structure. The disc 42 is hollow and is supplied with coolant in the form of lubricating oil through shaft 44, the oil leaving the disc through holes 80 to flow into an annular chamber 82 before returning to a sump. Alternatively, the coolant can be air bled from the compressor 14. The fuel for combustion chambers 37 is supplied to injectors in a predetermined sequence by a fuel pump 38 driven by one of the shafts 46, the latter also driving a rotary spark distributor for the ignition plugs. The timing sequence is arranged for the four combustion chambers 37 to fire one after the other or, alternatively, two at a time in opposite pairs. The power turbine and compressor shafts 86, 16 respectively may be connected by a clutch during engine braking. In modifications, each valve disc 42 may be replaced by a pair of poppet valves, and the axial flow turbine 104 replaced by a radial flow turbine.

Gaseous material flowing in tube 2 from a reactor is sampled by coiled tubes 3, 4 protected by filters 8, 9 positioned either side of orifice plate 1, which plate restricts the flow of material along tube 2. Inert gas, e.g. nitrogen or helium, entering by line 37, is passed through regulator 29, lines 28, 33 and 35, multiport valve 13 (connected as indicated by unbroken lines), and lines 10, 11 and 12 to orifices 5, 6, 7 at the far ends of and between, coiled tubes 3, 4 at a pressure slightly in excess of that of the material in tube 2 to be sampled in order to prevent material to be sampled to diffuse back into lines 10, 11 and 12. Inert gas is also passed by regulator 25 and line 24 to flush the column (not shown), and by line 32 to large chamber 31. When a sample is required, valve 26 is closed causing gas pressure in the column to fall, so obviating any risk that back pressure will prevent quantitative transfer to the column; multiport valve 13 is then switched to the connections shown by broken lines. Flow of inert gas to ports 5, 6, 7 ceases through lines 28, 33 and 35, but chamber 31 discharges inert gas at high pressure through lines 10 and 12, thereby sweeping the contents of tubes 3, 4 into line 11 and thence to the column. Multiport valve 13 is kept at a high temperature by oven 40 to prevent condensation of material in the valve.
