Title: Improvements in or relating to armatures for electrical machines
IPC: H02K21/10
Filed: 1942-09-23
Abstract: 559,598. Dynamo-electric machines. ERICSSON TELEPHONES, Ltd., WARD, S. H. D., and MORLEY, A. Sept. 23, 1942, No. 13392. [Class 35] [Also in Group XXII] Coils, magnetos.-An armature for a magneto or like machine comprises two U-shaped magnetic members 1, Figs. 1 and 2, pressed from sheet metal and arranged back to back, so that the joint between them, which may be riveted or welded, lies in a plane perpendicular to the axis of rotation. The members may be formed from I-shaped blanks, the wider portions of which are bent to form the arcuate poles 2 of the armature. The ends of the poles may have recesses 3 to accommodate non-magnetic end plates, as described in Specification 503,759. The outer corners of the central limb of each member may be rounded by a swaging operation to provide a circular core to receive the winding. Alternatively the core may be brought to a circular section by applying thereto a moulding of synthetic resin. In a modified construction each magnetic member is formed by drawing a metal sheet into the form of a cup, parts of the base and walls of which are then machined away to leave the central limb and arcuate pole pieces. One or more plates or laminations may be included between the two members.

Title: Improvements in and relating to the production of chlorine dioxide
Inventor: EVANS CYRIL HARRY
IPC: C01B11/02
Filed: 1949-05-24
Abstract: <PICT:0688206/III/1> In the process of preparing chlorine dioxide and chlorine by reacting an alkali metal chlorate and a suitable acid or acids, the aqueous chlorate and acid solutions are continuously fed as separate streams to a first unheated chamber and allowed to mix therein, while gaseous products are removed therefrom, the mixed liquids flow through the first chamber and pass, after a time, e.g. 1/2 min., not more than sufficient to allow the whole heat evolution to take place, into and through a second heated chamber in a time of 4-6 mins., while gaseous products are removed therefrom.  Solutions of sodium chlorate and chloride from tank 1 and sulphuric acid from tank 2 are pumped by pumps 5, 6 through filters 3, 4 and pipes 12, 13 to first chamber 14, having an inclined bottom.  The liquid mixture flows from chamber 14 through pipe 16, having glass packing which forms the liquid into a plurality of streams, into tower 22.  The liquid flows over helical glass bodies 17, through which thermostatically controlled heated water at 120 DEG -160 DEG F flows, in an elongated path, so that the liquid from one stage is not mixed with that from a later stage.  Spent liquid from tower 22 passes through float valve 18.  Air from blower 19 passes from distributer 20 to the bottom of tower 22 and thence upwardly, saturated with water vapour through tower 22 and chamber 14, sweeping out chlorine dioxide at a partial pressure below 12 mm. Hg. and chlorine, to outlet 23.  From outlet 23 the gases are passed with more air from distributer 20 to flowmeters 28, 29 for use.  U-pipe 35 connected to water tank 34 is provided to flood the apparatus should the air pressure fail.  A water injector may be placed at 23 if a solution of chlorine dioxide is required when the air circulation is dispensed with.  Specifications 510,678 and 546,282 are referred to.

Title: Improvements in and relating to devices for detecting, measuring or controlling the electric conductivity of liquids
IPC: G05D24/02
Filed: 1943-08-27
Abstract: 567,275. Resistance measurements; thermionic valve ammeters and voltmeters ; determining physical qualities of materials. LONDEX, Ltd., and SMITH, W. H. Aug. 27, 1943, No. 14003. [Class 37] Means for measuring or controlling the conductivity of a liquid such as petrol in a tank comprises an electromagnetic relay whose energizing coil is connected to the anode of an evacuated thermionic valve and is arranged to control the circuit of a fuel pump motor and also the circuit of an alarm or signalling device. Petrol under test is contained in a metal tank 1 in which is an insulated electrode 2. This is connected through a current-limiting resistance 3 and condenser 4 to the grid 5 of a thermionic valve of the ordinary evacuated type. In the circuit of the anode 7 is the energizing coil 6 of a relay having contacts 8 in the circuit of a motor 10 driving a petrol pump 11 and contacts 9 in the circuit of a lamp 12 or other signalling or alarm device. The valve is biassed so as normally to hold the contacts 8 closed and the contacts 9 open. If, however, a negative bias is supplied to the grid via the liquid path, the anode current is reduced and the coil 6 is de-energized, interrupting the circuit of the pump motor 10 and closing the signalling circuit. The cathode 13 of the valve is connected through a variable resistance 14 to one side of a secondary winding 15 of a mains transformer 16, whilst the grid 5 is connected to the same winding through a grid leak 17. The other side of the winding 15 is earthed to close the grid circuit through the earthed tank 1. The anode circuit is connected to the secondary winding 19, and a condenser 20 is connected in parallel with the coil 6 to keep it energized during negative halfcycles. The relay may also start the motor of a pump which is arranged to remove through a drain pipe 21 a water sump as soon as its level reaches the electrode 2. Two or more valves may be used in series or parallel. D.C. may be used instead of A.C. The invention is also applicable to the supervision or control of the quality of a non-conductive liquid in which a conductor, such as water, is emulsified. For this purpose, the anode current is measured. by bridge arrangements or recording instruments which can be graduated in percentage of water.

Alternatively the curve may be parabolic, a true radius curve, or a combined central circular and end angular shape. The tappet has a flat end 34 which engages a cam 12, and the bearing arrangement ensures line contact between the two. In a modification the peripheral surface of the guide bore 52, Fig. 6, is of axial convexity and the peripheral surface of the tappet body is cylindrical.

The ratio of the energy absorbed in the semi-conductor RH to that absorbed in the coil RK is preferably less than 1 : 4. The resistance RH must be maintained at the same temperature as' the coil RK, as must also the resistance RP if this has a positive temperature coefficient.
