Abstract: 455,933. Prepayment mechanism for meters. GLOVER & CO., Ltd., G., and STAPLES. C. W., Royal Avenue, Chelsea, London. May 20, 1935, No. 14685. [Class 27] Coin action, multiple-coin.-In a prepayment meter which can be set for use with either of two coins, a pivoted supplementary coin support, adapted to be moved into contact with the main coin support within a rotatable coin pocket when set for use with the smaller coin, is interconnected by a lever with a shutter for partially obscuring the coin slot. As shown, the main coin support c is pivoted at d and the supplementary support g at h within the coin pocket b. The supplementary support g is moveable into its alternative positions by a finger piece i working in a slot j in the coin pocket, the finger piece i being retractable against spring action to engage in locating apertures at either end of the slot j. The finger piece i also operates a pivoted shutter k, for adjusting the size of the coin insertion slot m, through the medium of a lever n pivoted at o to the coin pocket, this lever having a slot engaging the finger piece i and a second slot 24 engaging a pin 23 on the shutter k. To change the gear ratio between the meter driven shaft 6 and the screw-threaded shaft 8 of the quantity mechanism to correspond with the coin for which the coin pocket is set, a pivoted plate p is provided carrying a pair of coaxial gears 17, 18 and an alternative gear 16. In one position of the plate p, determined by a finger piece r engageable in apertures at either end of a slot in a plate t, the gear 16 connects a pinion 7 secured to the meter driven shaft 6 with a pinion 14 on the screw-threaded shaft 8, whilst in the alternative position of the plate p, the connection is provided by the gears 17, 18 meshing respectively with a gear 15 on the shaft 8 and the pinion 7. Specification 421,821 is referred to. Indicators.-An indicator dial y carried by a pivoted lever x having a pin-and-slot connection with the gear change plate p shows the consumer which coin the meter is set for.

Patent GB-940249-A (GB)
Title: Malting process
IPC: C12C1/047
Filed: 1961-04-26
Abstract: Loss in malting is reduced by a procedure involving acidulation of the cereal grain, e.g. barley, rye, wheat, oats, and addition of a growth-promoting amount of gibberellic acid, e.g. 1-3 parts per million of the grain, within the period from initial steeping of the grain until before the beginning of significant germination, the grain being then germinated until it is converted to malt, and the resulting green malt being dried. Gibberellic acid includes alkali metal and alkaline earth metal salts of gibberellic acid, alkyl esters such as the methyl, ethyl, propyl and butyl esters of gibberellic acid and acyloxy derivatives of gibberellic acid such as acetyl gibberellic acid. Acidulation entails steeping the grain in an acid aqueous solution, e.g. a sulphuric, hydrochloric, nitric, phosphoric, perchloric, acetic, monochloracetic or trichloracetic acid solution or sodium hydrogen sulphate solution, the degree of acidulation being ascertained by a described pH test. U.S.A. Specification 2,698,275 is referred to.  Reference has been directed by the Comptroller to Specification 811,374.
