Title: Improvements relating to telegraph relays
IPC: H01H53/015
Filed: 1926-07-28
Abstract: 276,808. Hall, I. F., and Sauvage, E. H. July 28, 1926. Eliminating effects of disturbing currents; systems employing non-contact-making relays.-Relates to relays of the kind in which moving contacts 29, 30 such as gold wires, co-operate with comparatively fixed contact butts 31, 32, the latter being however carried by a "damped jockey system " which turns with the axle 33, is damped by vanes 34 in oil, and is maintained by a "local correction coil" 37 (the connections of which are not shown) against movement due to a succession of impulses of like sign. The relay is similar to that described in Specification 128,102. According to the invention, wandering zero (due to earth currents or to faulty duplex balance or shaping signals) is prevented by causing the movement of the damped jockey system to apply. through its arm 4<a>, a correcting current to the line relay 28, Fig. 3. Thus if an earth current or other prolonged biasing current causes a deflection of the contact butts 31, 32, Fig. 3, about their axis 33, the arm 4<a> carries the middle electrode 5a of an electrolvtic cell 6a nearer to one or other of two fixed electrodes 7a, 8<a>, thus varying the resistances of the two sections of the cell. These sections form two arms of a Wheatstone bridge, the other two arms being formed by the resistances 9<a>, 10<a>, while the diagonals are formed by an alternating current source A and a rectifier B, the rectified output being passed to a coil 36 so as to restore the zero of the line coil 28 to its normal situation. The source A and rectifier B include reversing switches 12<a> 20a, which oscillate in synchronism, so that current from the battery 11<a> is applied to the bridge in alternately positive and negative impulses shaped by the condenser 19<a>, while the output (due to disturbance of bridge balance on movement of the electrode 5<a>) is commutated at 12<a> before being applied as a rectified current to the coil 36. In a modification an additional electrolytic bridge relay (comprising parts similar to A, B, 6a) is interposed between the line coil and the coil carrying the contacts 29, 30.

Title: Improvements in and relating to fluid heated heating devices
IPC: F24D3/00
Filed: 1967-04-24
Abstract: 1,222,509. Bed warmers. THERMEGA Ltd., and W. J. JENKINS. 28 March, 1968 [24 April, 1967], No. 18834/67. Heading A5X. [Also in Division F4] A blanket or other flexible member 1 has an internal tube 2 connected to an external, liquid-filled chamber 4, the latter containing a heater 10 and a superposed thermosensitive device 9. Energisation of the heater causes liquid to be supplied to the tube until the liquid level falls below device 9; the latter then reduces or cuts off the energy supply to the heater. As shown, liquid from tube 2 passes to a chamber 5 which is connected by a oneway connection, e.g. a non-return valve 1, to chamber 4, so that as the pressure in the latter falls, due to the deenergisation of the heater, liquid is sucked back into chamber 4 and the cycle subsequently repeated. In a modification (Fig. 2, not shown) the ends of the tube are connected to separate chambers each of which contains a heater and thermosensitive device, so that the liquid passes through the tube alternately in opposite directions. Alternatively, one chamber is used and the opposite end of the tube is closed (Fig. 3, not shown).

Title: Apparatus for lining up plates in front of the shears in shearing lines for rolling mills
IPC: B21D43/08
Filed: 1961-05-25
Abstract: 917,829. Shearing. MOELLER & NEUMANN G.m.b.H. May 25, 1961 [June 1, 1960], No. 18916/61. Class 83 (4). A plate 15 to be sheared is lined up on a rollway, Figs. 1 and 2, in front of shears 19 in a shearing line by means of levers 11 which are rocked to lift the plate to an inclined position relative to the rollway so that the plate slides to one side of the rollway and abuts against a trueing stop 16. The levers 11 in which are inserted rotatable guide rolls 12 are provided between the rollway rolls 10 and are rocked in groups about an axis 13 by a device 14. The stop 16 is constituted by shoulders formed on the levers 11. As shown, plates 15, 17 are obtained by slitting a blank by means of shears 18. During slitting the blank is held in alignment with the shears 18 by magnets 25 which are mounted on carriages 22, 23 slidable on tracks 24 and which also keep the plate 17 in alignment with parting shears 19. Rules 20, 21 are provided on both sides of the rollway for marking out lengths of the plates 15, 17 before parting. When carrying out a parting operation, the plate 17 which is already in alignment is fed to the shears 19 after the magnets 25 are released. The levers 11 are raised to tilt the plate 15 against the stop 16 and, after the plate 17 has been parted, are lowered so that the plate 15 can then be fed in its correct aligned position. In a modification, rocking levers are provided on both sides of the rollway and operated in turn to align the plates 15, 17. In a further modification, the plate 17 is lined up in a known manner against a trueing stop by a steering device or by inclined positioning of the rollway rolls. In a modification of the trueing stop the latter is formed by a curved surface on one or each of the rules 20, 21 and whose centre of curvature coincides with the axis 13. In a further modification used in front of edging shears where it is necessary to adjust the trueing stop the latter consists of stop blocks adjustably guided on the rocking levers by connecting-rods and cranks connected to a common spindle supported in bearings on or independently of the levers.

Title: Improvements in the conversion of carbon monoxide with hydrogen into hydrocarbons or their oxygen-containing derivatives
IPC: C07C29/156
Filed: 1936-07-14
Abstract: Hydrocarbons containing more than two carbon atoms or their liquid or solid oxygen-containing derivatives, e.g. alcohols, aldehydes and acids, are obtained catalytically from a mixture of hydrogen, carbon monoxide and inert gas containing less hydrogen than carbon monoxide, the inert gas, which is essentially carbon dioxide, comprising between 20--90 per cent, preferably 40--90 per cent of the mixture. Other inert gases such as methane or nitrogen may also be present. The concentration of inert gases may be maintained by separation of the constituents which are liquid between 0--50 DEG  C. under a pressure of 100 atmospheres after each passage through the reaction chamber.  When the concentration of carbon dioxide becomes excessive, it increasingly dissolves in the water formed or may be separated in the liquid form.  The process may be carried out at temperatures between 150 and 500 DEG  C., preferably 200--400 DEG  C., and preferably under increased pressure of 5--500 or more atmospheres. The preferred catalysts are those containing metals of the 8th group, particularly iron.  The fresh gas supplied may have a high content of carbon monoxide, e.g. from 40--70 per cent.  According to an example, a suitable reaction chamber consists of an externally heated tube containing about 30 layers of a catalyst consisting of ferrosoferric oxide containing uranium, titanium and potassium compounds (prepared by melting iron powder, titanium oxide, uranyl nitrate and potassium hydroxide in a stream of oxygen and reducing with hydrogen at 400 DEG C. and 150 atmospheres).  A mixture containing mainly about 51,0 per cent carbon dioxide, 22,0 per cent of carbon monoxide, 10,0 per cent hydrogen, 12,0 per cent methane and homologues and 3,0 per cent nitrogen is converted at 100 atmospheres and at a temperature of 265--300 DEG  C.  Liquid products amount to about 94 per cent, the remainder being methane and its homologues.  The fresh gas added comprises 3 pts. carbon monoxide and 2 pts. hydrogen containing about 0,5 per cent of nitrogen.  Specifications 337,409 and 338,854, [both in Class 2 (iii)], are referred to.ALSO:A catalyst suitable for the conversion of carbon monoxide and hydrogen into hydrocarbons and their oxygenated derivatives comprises ferrosoferric oxide containing uranium, titanium and potassium compounds and prepared by melting iron powder, titanium oxide, uranyl nitrate and potassium hydroxide in a stream of oxygen and reducing with hydrogen at 400 DEG  C. and 150 atmospheres.
