Filed: 1952-11-27
Abstract: 730,807. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27. 1952 [Dec. 1, 1951], No. 30089/52. Class 38 (5). [Also in Group XL (a)] A glow switch comprising a bimetal electrode 16 which moves to engage a fixed electrode 15 in an alkali-containing glass envelope 9 containing an ionisable atmosphere, e.g. a mixture of neon with ¢ per cent argon by volume, at a pressure in the range 40 to 80 mm., is provided with an alkali metal vapour absorbing getter 18 applied at least to the junction of the stem press 10 and the smaller electrode 15. The getter comprises a mixture of red phosphorus and thorium oxide, the thorium content being 20-65 per cent by volume. Preferably, the junction of the bimetal support 14 is similarly treated, and also the parts of the inleads 14, 15 and the stem 10 adjacent the junctions. The absorption of the alkali metal vapour prevents lowering of the ionising potential within the envelope 9 and thus when the switch is used in conjunction with an inductance to start a discharge lamp in known manner (Fig. 1, not shown), a sufficiently high starting voltage is available. The switch is intended for starting 85 w. krypton-filled fluorescent lamp as disclosed in Specification 667,070, [Group XL (a)], which requires at least 500 v. Specification 558,205 also is referred to.

Abstract: 484,310. Photo - electric cells. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and GILL, E. W. B. Nov. 6, 1936, No. 30328. [Class 39 (i)] In a soft photo-electric cell wherein amplification of the electron emission is required, the electron collecting electrode is spaced a long distance from the electron emitting electrode and means is provided for establishing a substantially uniform electric field between the electrodes.

Title: Improvements in or relating to variable speed power transmission gearing
IPC: F16H23/02
Filed: 1923-12-06
Abstract: 210,403. Lavaud, D. S. de. Jan. 24, 1923, [Convention date]. Variable-speed gearing comprising ratchet gearing driven from swash mechanism the inclination of which changes automatically with the load under spring control is described in Specification 189,087. This control spring 4, which has changing values of compression against load, is supported on a hydraulic piston 22 supplied through a valve 50 from a pump 51 operated by the driving-shaft 2.. The shaft 2 does not move longitudinally, but through a slot 10 in it then passes a pin 9 supporting the revoluble boss 8 of the swash mechanism. The non-revoluble wabbling hub 17 is supported on bearings 16 and is connected by rods 34 to the driven ratchets 42. A ring 18 forming part of the wabbling mechanism is connected by a fork 11 and a thrust member 3 to the control spring 4, which is preferably Belleville washers arranged in pairs. When the hydraulic pressure is released, a spring 32 acts through a rod 33 directly on the pin 9 to push the swash mechanism to a perpendicular no-drive position. As the pin 9 moves, cams 19 carried by the boss 8 slide upon a shaped part 7 of the shaft 2 to give the required tilting displacement. The rods 34 are connected to the hub 17 by ball joints 41. Oil passes through a passage 25 in the piston 22, through the thrust member 3, and through a duct 29 in the shaft 2 to lubricate the swash mechanism.

Title: Improvements in and relating to time indicators
IPC: G04F3/06
Filed: 1947-11-20
Abstract: 652,622. Time switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 20, 1947, No. 30824. Convention date, Nov. 22, 1946. [Class 38(v)] [Also in Groups XIX and XXXVIII] An electric switch is operated in addition to an audible alarm in an elapsed time indicator (see Group XXXVIII). The indicator is adjustable as to the timed interval, indicates visibly the time remaining in the interval and at the end of it operates the switch and alarm. In the Figs., which are front views with the indicator parts partly broken, a synchronous electric motor 1, 2 drives a pinion 5 through reduction gearing (not shown), and thence the main shaft 20 through gears 22, 23, 24, 25 and 26. Included in this drive is a friction clutch 27 which permits the angular position of the main shaft to be set by hand, a knob (not shown), being provided on an extension of the shaft at the front of the indicator. Gear 26 has teeth omitted over a small arc. Mounted on the main shaft is a cam 11 for controlling the alarm, the cam also carrying a pin 41, see Fig. 7, for actuating an electric switch 40, 42 simultaneously with the alarm. At the front of the apparatus see Fig. 3, is a dial plate 13 bearing a graduated time scale 35 and formed with an arcuate depression which starts at a slit 36 adjacent the zero of the time scale and extends for about 310 degrees. Behind the dial plate and mounted on the main shaft 20 is an indica-. tor member formed of a hub 32, a radial part 33 and an arcuate part 34. In operation the end 39 is guided through the slit 36 by a member 40 and as the main shaft is rotated passes along the depression to indicate against the time scale. To use the apparatus, the main shaft is first rotated clockwise by hand to set the end 39 against the desired time, 54 minutes, say, as shown in Fig. 6. On release, the motor drives the main shaft anticlockwise and the indicator 34 slowly disappears through slit 36, the exposed length of indicator showing the time remaining in the time interval. As the end 39 finally disappears at zero time see Fig. 7, pin 41 actuates the switch and simultaneously gear 26 disengages gear 25 to stop the drive. One pair of switch contacts may be connected to break the drive motor circuit.

Induction coils 21 are arranged around the passage in the vicinity of a bath or they may be embedded in the walls in this neighbourhood. After passing through the treating baths the articles, if necessary, are conveyed through a spray rinsing apparatus and a drying oven. Specification 262,439, [Class 72], is referred to. The Specification as open to inspection under Sect. 91 comprises also the application of the process to cementation, nitriding metals by heating them in ammonia vapour and heat treatment generally. This subject-matter does not appear in the Specification as accepted.

Patent GB-690885-A (GB)
Title: Improved crystallizing process, particularly for the separation of esters of fatty acids
IPC: C11B7/00
Filed: 1950-12-20
Abstract: A liquid mixture of fatty acid esters of monohydric alcohols having 2-4 carbon atoms and substantially free of foreign solvents is cooled to crystallize esters of higher melting-point which are separated. By successive cooling steps, fractions of successively lower melting-points are obtained.  Fatty acids and their derivatives in natural mixtures may be separated into fractions of different degrees of saturation by converting into esters with, for example, ethyl, n-propyl or butyl alcohol, and crystallizing.  The separated esters may be hydrolysed to reform the acids or derivatives.  The fatty acids are those of at least 6 carbon atoms, particularly those from lard, tallow, soya bean, cottonseed, coconut, palm kernel, palm, linseed, castor and tung oils or the like.  The liquid ethyl esters of lard fatty acids are cooled at 0 DEG  and filtered at 6 DEG  C. to remove the crystalline precipitate.  The filtrate is cooled and filtered at - 5 DEG  C. and this filtrate cooled at - 10 DEG  and filtered at - 5 DEG  C.  The last precipitate is returned for re-working.  The last filtrate is essentially oleic acid.  The precipitates of the first two stages are combined, warmed to liquefy, cooled at - 6 DEG , and filtered at 6 DEG  C. to give stearic and palmitic acids, the filtrate being recycled.  Ethyl esters of mixed oleic and linoleic acids are similarly cooled in stages, the first and second precipitates being combined, liquefied and cooled to precipitate the oleic ester.
