Title: Improvements in or relating to coin freed amusement apparatus
IPC: G07F17/32
Filed: 1933-12-27
Abstract: 430,669. Games of chance. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., Pennywell Road, and DOLMAN, H. J., Church Road, Staple Hill, both in Bristol. Dec. 27, 1933, No. 36313. [Class 132 (ii)] [See also Group XVIII] A coin-freed amusement apparatus of the kind comprising a scoring-disc which, after insertion of a coin, is set in rotation and subsequently stopped, is provided with a totalizing member that sums up the successive scores obtained. When the total score reaches or exceeds a predetermined amount, a prize is delivered. After prepayment, a rod 12, is depressed by a finger-piece to depress a lever 32 and wind-up clockwork 34, driving mechanism for a scoring disc 2, integral with a toothed wheel 10 and a stepped cam 11, being also stressed. Return of the rod 12 by spring action releases the driving mechanism to rotate the disc 2, which the player then endeavours to stop in a scoring position by a spring pressed finger 35 released by a pressbutton to engage the wheel 10. If the manual control be not used, the disc 2 is stopped automatically in a non-scoring position by a finger 36 released by the lever 32 which is returned slowly to its initial position under control of the clockwork 34 by a spring 51. The lever 32 by engaging a stop 37 also rocks a pivoted arm 38 and through a link 40 rocks an arm 41 to release a detent 43 from a plunger 28 which is pivoted at 27 to a toothed quadrant 22 and passes through a guiding hole 30 in a fixed bracket. Should the disc 2 stop in a scoring position, a spring 24 rocks the quadrant about its pivot 23 to an extent determined by the depth of the step 44 or 45 on the cam 11 engaged by the plunger 28. The quadrant rotates a wheel 20 rigid with a ratchet wheel 17 which is engaged by a pawl 18 pivoted to a wheel 15 integral with a totalizing wheel 4, backward rotation of which is prevented by a pawl 14. The wheel 4 is thus driven forward an amount corresponding to the score gained on the disc 2, overrunning being prevented by an escapement device 50 engaging the wheel 15. If there is no score, the quadrant cannot move since the plunger 28 then engages the cam 11 between the steps. The quadrant is returned to its initial position at each actuation by a pin 31 on the rod 12. The machine may be again operated by insertion of another coin, the wheel 4 being each time actuated so as to totalize the score. When the wheel 4 has been turned through an angle of 180 degrees, a crank 16 fixed to its shaft engages and rocks a lever 46 to actuate a prize-delivery mechanism. The crank 16 will then have been brought past its outside dead centre, and a spring 47 will rotate it and the wheel 4 through a further half-revolution to zero position. The parts are then in their original positions ready for replay.

Title: Process for the production of zinc salt solutions
IPC: C01G9/00
Filed: 1929-11-29
Abstract: 334,458. Metallges. Akt.-Ges. Dec. 7, 1928, [Convention date]. Addition to 302,924. Zinc sulphate and salts thereof in general; lead sulphate.-Raw materials containing zinc oxide are first leached with acid in the manner described in the parent Specification to extract the bulk of the zinc without extracting other metals present, and the residue then leached with considerable excess of acid, the acid liquor thus obtained being treated with sulphuretted hydrogen or a sulphide such as iron or zinc sulphide to free it from metals such as copper, cadmium, arsenic, and antimony. Iron introduced into or remaining in the acid liquor may be removed by oxidation, for instance with a persulphate, permanganate, or manganese dioxide, followed by neutralisation with zinc oxide, and the neutral liquor be added to the main solution, or the two solutions may be mixed before or after oxidation of the iron. Residual impurities, such as nickel or cobalt, may be precipitated with zinc dust before, or after oxidation of the iron. The ferrous or zinc sulphide used to precipitate impurities may be formed by decomposing the "sulphide " precipitate in the presence of alkali or alkaline earth oxides by means of iron or zinc compounds, for instance with the ferric hydroxide precipitated later, with or without first reducing it by zinc dust, iron, or the slime containing zinc obtained in the precipitation with zinc dust. When the process is combined with electrolytic recovery of zinc from zinc solutions, undesired accummulation of iron in the circulating liquor may be prevented by discarding an amount of iron equal to that dissolved each time the liquor circulates. When lead is present in the ore treated and sulphuric acid is used for the second leach, it is recovered as pure lead sulphate.
