Abstract: 1,149,061. Change-speed planetary gears. EMERSON ELECTRIC CO. 15 April, 1966 [30 April, 1965; 18 March, 1966], No. 16747/66. Heading F2D. A two-speed gear for a washing machine comprises a two- or three-element epicyclic train having axially movable clutch means engageable to prevent relative rotation of two elements for direct drive, and means to hold one element against rotation for reduced drive. As shown in Fig. 2, a two-element train comprises a ring gear 85 fast on an output shaft 48 and a planetary pinion 80 having one less tooth than the ring gear and fast with a sleeve 76 which is rotatably mounted on a crank pin 70 fast with an input shaft 23 driven by an electric motor. The sleeve 76 is connected by a web 75 through axial pins which engage, with play permitting gyratory motion of the sleeve and pinion 80, in apertures in a clutch/brake ring 52. The ring 52 has coned clutch and brake surfaces engageable with correspondingly coned surfaces 35, 25 formed respectively on a member 30 slidably splined to the input shaft and on a stationary housing 44. A spring 90, reacting between the member 30 and the ring 52, urges the ring 52 into clutching engagement with the member 30 to thereby lock the train solid for direct drive. The member 30 is slid axially by electromagnetic or hydraulic means acting on a shifter fork 64, to first engage the ring 52 with the brake surface 25 and subsequently to release the ring from the clutch surface 35 so that the pinion 80 is held from rotation but permitted, by the play in the connection to the ring 52, to gyrate to give reduced drive. In another embodiment (Fig. 5, not shown) a three-element train has an input sun, an output carrier and a ring gear formed with clutch and brake surfaces for selectively clutching the ring gear to input for direct drive and stationing the ring gear for reduced drive. In a modification of this embodiment (Fig. 7, not shown) the ring gear is clutched to the output carrier for direct drive.

Title: The preparation from liquorice of products having a cortisone-like activity
Inventor: MITCHELL WILLIAM
IPC: A61K36/484
Filed: 1953-07-01
Abstract: An aqueous solution of an extract of liquorice root is contacted with an anion exchange material, the anion-exchange material is washed with water, the material retained thereon is eluted with a dilute aqueous solution of an acid, and the eluate neutralised with alkali to give a product having a powerful cortisone-like activity.  The neutralised eluate may be mixed with alcohol of at least 90 per cent v/v strength, clarified and evaporated to yield a product constituting about 50 per cent or less by weight of the first residue and possessing substantially all of the cortisone-like activity.  The anion-exchange material may be eluted with dilute hydrochloric acid, and the eluate neutralised with dilute sodium hydroxide or ammonia. The effluent and washings from the anion-exchange treatment may be acidified with e.g. acetic acid, to a pH of about 5.0 and evaporated in vacuo to yield a liquorice extract free from substances possessing cortisone-like activity.  In an example a liquorice extract dissolved in distilled water is filtered and passed through a column of anion exchange material previously prepared by contact with 8 per cent v/v aqueous sodium hydroxide.  The resin is then washed with water until the washings are no longer alkaline to litmus.  The effluent and washings are reserved.  The column is eluted with 1.8 per cent v/v hydrochloric acid and washed with water.  The eluates are combined, made alkaline to litmus with ammonia and evaporated in vacuo.  The residue, which possesses the cortisone-like activity, is mixed with 95 per cent v/v ethyl alcohol, filtered, the residue washed with alcohol and the alcoholic filtrates evaporated in vacuo.  The residue obtained is taken up in absolute alcohol, filtered and the filtrate evaporated to give a purified product.  The effluent and washings from the anion-exchange treatment are made acid with acetic acid to pH 5.0, and concentrated in vacuo to give an extract possessing the flavouring, demulcent and expectorant properties of the initial extract but free from cortisone-like activity.
