Convention date, Dec. 7, 1929. [Class 39 (i).] Positive-column discharge tubes are provided with a filling of a colour-producing vapour and krypton or xenon and with a cathode of a refractory metal coated with an alkali metal. A current density of À5-1 À5 amps. per sq. cm. of cross section of the gas column is used so that a tube 1 of length above one metre and of 8 mm. internal diameter can be operated at the voltage of commercial mains. The filling may be krypton at 2-30 mm., preferably 5-15 mm., together with mercury vapour producing blue light. A cathode 2 of iron, copper, or nickel is coated with potassium, lithium, sodium, or caesium and the tube walls near the cathode may be similarly coated. The alkali metal is distilled into the cathode chamber, or a pellet is vaporized by external heat or by the heat of a heavy discharge. For alternating current, the anode 3 is similarly coated or two anodes are used. Rings 20 space the electrodes 2, 3 from the walls. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use instead of krypton or xenon of other low-potential gas such as argon and refers to other alkaline cathodes. The cathode may be made by coating with a compound such as potassium nitrate or azide and heating by a heavy discharge to remove occluded gases and to form a metallic or emissive residue. This subject-matter does not appear in the Specification as accepted.

The carboxylic buffering and complexing agent may be sodium citrate or citric acid, tartaric acid, oxalic acid and salts thereof. The substrate may be agitated, e.g. ultrasonically, during the coating process to ensure a uniform coating. Prior to the coating process the substrate is cleaned either electrolytically or by means of trichlorethylene and may also be treated with H2SO4 or HCl.

The main sliding wheel pairs 6 ... 9 are actuated selectively through a slide-turn shaft 12, universally jointed at 57, 58 to a single manual shift lever 33, 40, guided by an H-slotted gate 30, which is axially shifted by the shift lever 33 to actuate, through a rod 22, the auxiliary gear-wheel 17, whereby the gate 30 assumes one of two positions corresponding to high or low range, in each of which identical movements of the shift lever select the four main ratios. The shift lever 33 is fast to a block 40 having an upper head 28 engaging the gate slot 29, and a lower roller heel 25 engaging a fixed rectangular groove 26 surrounding a stop 32. The slide-turn shaft 12 actuates the main shift-forks 10, 11 through a toothed wheel 13 selectively meshing wheels 14, 15, respectively. In operation, with the heel 25, as shown, in the outer part 26A of the groove 26, the manual lever 33 selects ratios I to IV in the corresponding gate positions, Fig. 3, the heel 25 moving to opposite ends of the groove part 26A during gear establishing movements of the lever to occupy positions I<SP>1</SP>, III<SP>1</SP> or II<SP>1</SP>, IV<SP>1</SP>. To change range the shift lever 33 must be in a gear position, say IV. The lever is pulled further outwardly (right), taking with it the gate 30 to the chain-line position, Fig. 3, which through the rod 22 establishes high range in the auxiliary gear, and ratio VIII overall, the heel 25 now occupying the inner section 26B of the groove 26. Ratios V to VIII can now be establisned at the same corners of the gate 30 as the previous I to IV, the heel 25 occupying corresponding positions V<SP>1</SP>, V<SP>11</SP>, and VI<SP>1</SP>, VIII<SP>1</SP>. A transparent window 45 covers the gate 30.

In order to increase the starting torque of a single phase induction motor having main and auxiliary windings forming angularly displaced main and auxiliary poles, at least one slat of the stator is shared by a coil side of a main winding coil and a coil side of an auxiliary winding coil, one of the coil sides having a space factor of at least 80% and the number of turns in each of the coils being so selected that the algebraic products of the third harmonic effective main and auxiliary winding turns and of the fifth effective main auxiliary winding turns are respectively less positive and less negative than in a motor having no coil side with a space factor of at least 80%. Each winding comprises a plurality of concentric coils of progressively increasing pitch. The permanent split capacitor motor shown has two main poles 18a, 18b, and two auxiliary poles 24a, 24b, each of the main poles having five coils M1-M5 and each of the auxiliary poles having four coils S1-S4. To allow the use of a larger number of turns in the coils as compared with prior art motors, at least those main winding coil sides sharing a slot with an auxiliary winding coil side (excluding the coil sides in slots 14a, 14e) are compacted to give a space factor of at least 80%. Two examples are given of motors wherein the numbers of turns in the coils of the auxiliary winding progressively increase from the smallest to the largest pitch coil and wherein the numbers of turns in the coils of the main winding progressively increase from the smallest to at least the second largest pitch coil. The largest pitch coils of a given pole may be divided into two or more series connected sections made of different materials, e.g. copper and aluminium.
