[Also in Group XII] An axial flow gas turbine with an annular space before the blade lattice has the annular space subdivided into two portions by an annular separating wall which is corrugated transverse to the turbine axis with warm and cool fluids flowing through the inner and outer portions respectively which fluids pass through apertures in the wall to mix and thereby produce a temperature gradient before the blade lattice so that the temperature decreases in the radial inward direction. In the arrangement shown, the casing 1 has an annular corrugated insert 5 arranged in the annular space before the row of stator blades 2a. The space on the inner side of the insert 5 is connected through a branch 6 to a source of cooling air which passes through apertures 5b and mixes with the gas supplied to the turbine. Additional apertures 5a may also be provided. In a modification, the gas is supplied to the turbine through a duct surrounded by an air jacket through which the cooling air flows. In this arrangement the corrugated insert is made in two parts for assembly reasons and the turbine casing is made of welded steel and is supported from an outer casing, which is also of welded construction, by means of radial bolts. The space between the two casings forms the cooling jacket. The inlet duct is connected to the inner casing by means of clamping rings. In a further modification, the inlet duct forms a reheat combustion chamber. In this arrangement the cooling fluid is a gaseous fuel which is arranged to mix with the working fluid so that it is burnt in the outer part of the annulus.

Abstract: 679,879. Electrolytic cells; electrolytic production of hypochlorites. EVANS, D. J. May 4, 1951 [May 4, 1950], No. 11019/50. Addition to 638,694. Class 41. [Also in Groups XXVIII and XXXVII] A combined pump and electrolytic cell apparatus as described in the parent Specification is modified in that the piston or diaphragm of the pump is operated not by solenoid apparatus but by means of an electric motor which drives a face-cam through reducing mechanism of epicyclic or worm-gear type, the face-cam rotating upon a vertical axis slightly offset from the axis of the pump and cell unit. A second modification is in the automatic means for reversing the polarity of the rectified current supplied to the cell (see Group XXXVII). A third modification, which may be used with the apparatus described in the parent Specification or with the apparatus having the modified means described above for operating the piston or diaphragm of the pump, is the association of the combined pump and electrolytic cell unit with a salt saturator located above a cylindrical base in which the unit is pivotally mounted. The saturator is for use in the production of hypochlorites. As shown in Fig. 4, an electric motor M is provided with reducing mechanism which drives a face-cam 73 rotatable upon a vertical axes slightly offset from the axis of the cell. The face-cam is in contact with a roller 74 fitted to a rod 54 connected to the pumping diaphragm 46, so that the diaphragm is forced upwards twice during each revolution of the cam, against the action of a spring 66. Brine from a salt saturator is therefore pumped past a delivery valve 59 and through a narrow gap between approximately semi-cylindrical electrodes in the cell A, to an outlet 63. The pump may be provided with a non-return inlet valve if necessary. The combined pump and cell unit is mounted within a chamber A, Fig. 1, which is located below the salt saturator B, shown in part only, the unit being bolted to a plate 18 pivotally mounted about a vertical axis 19 so that the unit may be swung out of the chamber A, when required for inspection or maintenance.

April 9, 1930, No. 11296. Convention date, May 2, 1929. [Class 139.] Synchronizing.-In a synchronized clock system the secondaries are released, at the synchronizing time, by a sustained flow of current longer in duration that the duration of the normal and accelerating impulse supply. By this sustained flow thermostatic means are operated to render ineffective devices which arrest the secondary clocks just prior to the synchronizing moment, so that the secondaries restart on time. In the master clock, contacts 14, 16 are closed once an hour, contacts 17 once a minute, and contacts 19 are closed by the escapement 11. With switch 32 in the normal position shown an impulse is sent once a minute to the secondaries 21 through circuit G, B, 32, 17, 34, G. Magnet 34 closes, at 35, the circuit G, B, 35, 37, 21, G. When contacts 16 close 10 seconds after the 59th minute, rapid impulses are sent through contacts 19 to step up any slow secondaries ; 20 seconds before the hour, contacts 14 close for twenty seconds to give a steady current through the coils 52. At each secondary, magnets 21 and pawls 21a drive the ratchet 22 on the minute hand arber 20 at each minute impulse through 17, until the secondary indicates the hour exactly. At this point an abutment 50 on wheel 22 is arrested by a bimetallic strip 51. At the hour by the master clock, contacts 14 send a steady current to the coil 52 (in series with magnet 21) which warps the bimetallic strip 51 and releases lug 50 so that the secondaries restart on time. Specification 261,258, [Class 139, Watches &c.], is referred to.
