Abstract: 635,785. Purifying liquids; treating sewage. INFILCO, Inc. July 15, 1947, No. 18794. Convention date, Aug. 13, 1941. [Classes 46 and 111] Water-treating apparatus comprises a tank, a horizontal agitator imparting mainly rotational circulation to liquid in the lower part, baffle means above the agitator providing a quiescent zone above, an upwardly-extending partition structure forming a mixing and reaction chamber communicating with the circulation zone by an inlet opening and an outlet opening spaced apart vertically, impelling means causing flow through the chamber, means to supply liquid to be treated and treating reagent to the chamber, a treated liquid outlet from the top of the tank, and a solids discharge outlet. As shown in Fig. 1, water and solids remaining from previous treatment are given a largely rotational motion in the lower part of a tank 10 by an agitator 20 on a rotating shaft 21 which also carries an impeller 37 arranged to cause a downward circulation in an inner cylinder 32 with flared lower end 36. The circulation thus set up causes an upward current of slurry between the cylinder 32 and an outer cylinder 30, to which are supplied water to be treated, at 44, and chemical reagent at 41 under a small shelf 45. As clarified water rises between the outer cylinder 30 and tank wall 11, radial baffles 28 having their greater width in the vertical plane check its rotational motion. In a modification, the impeller 37 is adapted to cause circulation in the opposite direction, the water and reagent are supplied to the flared und 36 of the inner cylinder 32, the lower end of the outer cylinder 30 is closed, and the slurry, which in this case moves down into the space between the cylinders, is distributed by pipes extending radially from the outer cylinder 30 and having spaced openings along their lower surfaces. In the modification shown in Fig. 4, the lower part 60 of the inner cylinder is attached to the agitator 20 and rotates with it ; vanes 29 are provided on the lowermost baffle 28 ; and the perforated pipes 53 are above the lower baffles. The flow of slurry is also preferably reversed, i.e., into funnels 66 at the ends of the pipes 53, down into the inner cylinder 32 and out through the lower end 62.

Title: Improvements in coin detectors
IPC: H04B1/08
Filed: 1925-07-31
Abstract: 253,739. Chester, F. R. July 31, 1925. Magneticseparators. - Relates to an electric coin detecting system of the kind comprising a primary and a secondary circuit which provide two pairs of inductively associated coils, one pair being arranged adjacent to the coin shoot so that an inserted coin has an inductive effect on the system, which effect is utilized to produce a mechanical action such as to permit or prevent the sending of a signal. According to the invention, in such a system, the movable parts and the electrical system are self-serving and are automatically restored after the passage of the coin to their condition prior to its insertion. The system comprises a primary circuit 5, Fig. 1, having two coils 7, 8 in series and a secondary circuit 6 with two oppositely wound coils 9, 10, the pair 7, 9 surrounding a coin shoot 11 which has two diverging branches 11<a>, 11<b>, Fig. 3, leading to a coin box and to a return shoot respectively. A ,coin inserted in the shoot, actuates during its travel a pivoted arm 24 to close a switch 27 in the circuit 5. If the coin is a proper one it has such an inductive effect that the induction between the coils 7, 9 balances the induction between the coils 8, 10 and the coin passes on by way of the branches 11<a>. If an improper coin is used, the induction between the coils is not balanced and a current flows in the circuit 6 to actuate a relay 18, 20 thereby closing a circuit 19 containing an electromagnet 21. This actuates a switch 15 pivoted at the junction of the branches 11<a>, 11<b> to divert the coin to the return shoot 11<b>. In each case, as soon as the coin passes, the circuit 5 is opened and the parts are restored to their normal position by springs. The coils 9, 10 are carried bv sliding sleeves 29, 30 respectively, so that the system can be adjusted for a coin of any desired denomination. In making the adjustment, the coin is held in the shoot 11 in the position for closing the switch 27 by a stop pin temporarily inserted in the shoot.
