Title: Method of and apparatus for the purification of sewage or sludge
IPC: C02F3/34
Filed: 1958-01-02
Abstract: 882,709. Treating sewage. NEIDL, G. Jan. 2, 1958, No. 144/58. Class 111. Sewage or sludge is purified by passing a single-or multi-phase alternating current between spaced, vertically disposed, parallel, rodlike or tubular electrodes immersed in an open settling tank containing the sewage or sludge, the electrodes being so-positioned in the tank that the spacing between each neutral electrode and each of its associated live electrodes is smaller than the spacing of each live electrode from the boundaries of the tank. With a threephase alternating current, the electrodes are preferably arranged in pairs, Fig. 2, each phase being connected to a separate live electrode 13 which is positioned opposite a neutral electrode 14, and in this case the distance 16 between each pair is greater than the distance 7 between the electrodes of each pair. With a single-phase alternating current, a plurality of live electrodes 18, Fig. 3, may be grouped around a single neutral electrode 17, and screens 19 may be interposed between the live electrodes and the walls of the tank. When tubular electrodes are employed, aeration of the sewage may be simultaneously effected by passing air downwardly through them. Methane withdrawn from the tank may also be caught up and returned, along with air, through the tubular electrodes. The electrodes may be suspended from a bridge which is movable along the upper edges of the tank, if desired, at high speed, whereupon movement of the electrodes also effects an aeration of the sewage. Means may also be provided to move the electrodes along the bridge. The alternating current may be intermittently applied. Quantities of sewage treated and activated by the process may be mixed with untreated sewage, the activation being such as to effect a purification of the mixture, without further electrical treatment.

Title: Process for preparing light-stable polyurethane elastomers and products obtained thereby
IPC: C08G18/76
Filed: 1966-01-05
Abstract: 1,133,834. Polyurethane elastomers. F. URGESI. 5 Jan., 1966 [5 Nov., 1965], No. 433/66. Heading C3R. A light-stable polyurethane elastomer is made by reacting (1) a hydroxyl-containing aliphatic polyether or polycarbonate, or a hydroxylcontaining aliphatic polyester which contains no residue of adipic acid, with (2) an aliphatic, aromatic-aliphatic or cyclo-aliphatic diisocyanate and with (3) an aromatic or aromaticaliphatic diol, the quantity of the diol used being molecularly greater than the quantity of polymer (1) used. The preferred polymers (1) have a M.W. from 1000 to 2000, and are polyesters made from aliphatic dicarboxylic acids having 4 to 10 C. atoms (except adipic acid) and aliphatic glycols having 2 to 8 C atoms or polycaprolactone, polyethers made by polymerizing ethylene or propylene oxide or tetrahydrofuran, and polycarbonates made by reacting aliphatic carbonates and glycols. Diols (3) can be esters of aromatic acids with aliphatic or aromatic glycols, or of oxyacids with glycols having at least one benzene nucleus or the diphenols; diols of the formula wherein Ar = one or more aromatic nuclei, n = 1 to 10, and m = 1 to 5; condensation products of ethylene or propylene oxides with aromatic glycols or diamines; or ethoxylation products of the ester of an aromatic dicarboxylic acid with an aliphatic glycol. Many examples are given of these diols and of diisocyanates. In addition, 1,4-butane diol can be added to increase the number of rigid urethane linkages. The reaction can be effected in one or more stages, and where carried out in more than one stage, the last stage is effected in suitable solvents. Where the polymers are dry spun or extruded in the absence of solvents, crosslinking is obtained by using a controlled excess of diisocyanate or by adding triisocyanates or triols. If desired, melt spinning may be carried out from polymers which are not completely formed, and the reaction is then completed by heating the yarn. In a typical Example (1), p-xylylene and 1,4-butane diol were added to a charge of polycaprolactone and TiO 2  which had been dehydrated under vacuum at 248‹ F., the mixture being maintained at 248‹ F. for 1 hour, and then hexamethylene diisocyanate was added and the temp. raised to 347‹ F.; the resulting polymer was discharged, cooled and suitably cut prior to melt spinning.

Abstract: 102,071. Compton, J. H. Jan. 11, 1916. Wind instruments; actions; expression-controlling; tempo - regulating means.-The stop, swell, tempo, or other mechanism of an organ is actuated in one direction by the simultaneous operation of control and governor devices, and in the other direction only when the governor device becomes operative alone, the arrangement being thus self-locking, so that a stop having been drawn by a double perforation in the tune-sheet remains in that position until returned by a single perforation. In the electric action shown in Fig. 1, control and governor contacts 10, 14 in the tracker control the action of magnets 13, 16 on switch arms 18, 23 respectively, to close the circuit of the stop or other magnet 3; this circuit includes an additional magnet 7 for retaining the arm 23 when both contacts 10, 14 are open, this magnet being short-circuited by contacts 9 on the arm 18 to release the arm 23 when the contact 14 is closed by itself. In the pneumatic action shown in Fig. 2, the valve disk 27 is of 'larger area than the pneumatic 28 connected to the control aperture 29, so that the stop or other rod 26 can only be moved when the valve 34 is moved by the pneumatic 32 connected to the governor aperture 31 to cut off the supply of wind from the pressure chamber 36 and exhaust the chamber 35 by the port 38. The control and governor devices may be arranged in a cluster at one or both ends of the tracker, and one governor device may cooperate with several control devices.

Abstract: 121,826. Barron, C. A. Jan. 9, 1918. Drawing wire.-In a continuous wire-drawing machine, the finishing drum a of a series of draw drums is driven by a differential gear, one member of which is formed with a grooved pulley acted on by a brake block which is adjusted so as to accelerate the speed of the finishing drum according to the diameter thereof, and a. similar differential drive is automatically controlled by passing the wire over a weighted lever which controls the braking pressure on the brake fixed to the part of the differential, and thereby automatically controlling the speed of the draw drums. As shown, the differential drives for the finishing drums a comprise sprockets g freely mounted on sleeves h freely mounted on a countershaft f. A sun wheel j on each sleeve h meshes with planet wheels k mounted loosely on studs l on each wheel g. The wheels k mesh with an internal toothed ring p on a disk q keyed to a bevel-wheel e geared to a bevel-pinion e<1> on the shaft of each finishing drum a. Spring-pressed pawls on the wheels g normally engage teeth on the ring p and the whole rotate together, but when pressure is applied bv a screw s to a brake i integral with the sleeve h, the sun-wheel j is retarded and the motion of the ring p and of the wheel e is advanced. The screw s is set in accordance with the diameter of the drum a. The wire as it passes between the draw drums may be passed over a pulley w<2> on a counterweighted lever which is connected to a brahe-stra.p which controls the motion of the draw drums in a similar manner to that in which the screw s controls the drum a.

Pilot valve apparatus.-In a thermostatic boiler feed regulator, the thermostat is arranged at an angle across the water fine of the boiler, and operates, by means of a pilot valve, a feed valve forming a separate unit which may be arranged at a distance. The thermostat comprises a lower chamber 1 connected by a long tube to the water space of the boiler, an upper chamber 2 connected by a short tube to the steam space of the boiler, and a connecting tube 3 having a small expansion coefficient. A metal rod 4 having a higher expansion coefficient is fixed at 5 and slides through a stuffing-box. A lever 8 is pivoted at 9 and its movements are controlled by the rod 4 and spring 12. The free end of the lever 8 operates a piston valve 16 having annular grooves 17, 17<a>, the latter being connected to the space at the end of the valve. The passage 18 is connected by a pipe 18a to the pressure chamber of the main valve, and the passages 19, 20 to the inlet and exhaust for the pressure medium. When the rod 4 is contracted due to a high water level in the boiler, pressure fluid passes into the chamber 21 of the main valve, keeping the valve closed. A reverse movement of the rod 4 places the chamber 21 to exhaust through the valve 16, and allows the spring 24 to open the valve. An alternative arrangement is described in which the valve 16 is replaced by a double-seated cone valve. In another form, the auxiliary valve is adapted to retain or release the pressure fluid which enters the pressure chamber of the main valve direct.
