Patent GB-418337-A (GB)
Title: Process for purifying waste water
IPC: C02F1/52
Filed: 1934-02-05
Abstract: Waste water is purified by the precipitating action of ferric hydroxide produced in the water from metallic iron by addition of carbon dioxide and subsequent treatment with oxygen.

In the boiler 21, fines separated from the synthesis gas product in a high efficiency cyclone separator 19 are used as fuel for heating the water condensed from the synthesis gas product in the scrubbing system 25, together with make-up water, to make steam. The process may be carried out at atmospheric pressure, or at elevated pressures up to 2000 p.s.i.a. The gasification reaction generally takes place at temperatures in the range of 1000-1250 C. The synthesis gas product can be used directly as a fuel or as feed gas for the synthesis of methanol and methane. Carbonaceous materials: coal, lignite, char, wood refuse, paper, manure or municipal solid carbonaceous waste. A detailed working example is disclosed of the production of synthesis gas from lignite.

[Class 60.] Trueing rotating tools.-A device for attachment to a grinding-machine for trueing the grinding- wheel in situ enables wheels having convex or concave surfaces of different diameters to be trued the trueing tool being rotatable about either of two centres of rotation. A base 1 bolted to the machine at 4 carries rotatably a guideway 7 having arcuate bounding edges with a point B as centre and pivoting about a conical head 11. A dovetail guideway 17, on which a standard 21 carrying the trueing diamond 24 is adapted to slide, is provided on a slide 15 supported on the base 1 and engaging the guideway 7, the standard 21 being thus rotatable about the axis A of pin 11 or about the centre B.

A gauge block is employed to locate the diamond point 24 in line with index marks 36 or 37 on the standard 21 and by means of an adjusting screw 26 the point is adjusted at the correct distance from the centre of rotation A or B as shown on a scale S. The standard may be reversed end for end and numerical details of the correct position of the standard and the correct centre of rotation to be used for different curvatures are given in the Specification.

IPC: H01G4/12
Filed: 1964-01-31
Abstract: 1,044,444. Solid electrolyte capacitors. STANDARD TELEPHONES AND CABLES Ltd. Jan. 31, 1964, No. 4199/64. Heading H1M. A capacitor includes a body having a porous conductive core 2 coated with dielectric 4, the pores of the body being lined by the dielectric coating and the dielectric coating being covered with solid conductive material 7 except at one end of the body 5, where the pores are impregnated with solid insulating material 3. At this end an electrode 8 is secured in ohmic contact with the conductive core, and is insulated from the solid conductive material by means of the insulating impregnating material. The porous core may be formed of high dielectric constant ceramic material, chemically reduced to be conductive. The dielectric coating is formed by reoxidation of the surfaces of the ceramic material. To carry out the impregnation of the portion 5 of the body, it is dipped into a bath containing a silicone rubber compound and a catalyst. This is cured and then the remainder of the body is impregnated with a solid semi-conductive composition of manganese dioxide, which forms the conductive material 7. Over the material 7 is deposited a conducting layer 9. This is formed, together with the electrode 8, by the simultaneous evaporation of chromium and silver. Alternatively, aluminium, nickel, copper, silver or gold may be applied by evaporation or sputtering techniques. A coating of colloidal silver may be applied to the codeposited chrome-silver surfaces, and the body is encapsulated by a layer 12 after lead wires 10 and 11 have been soldered to the electrode 8 and the layer 9.

Title: Improvements in engines having a blade wheel
IPC: F03B13/04
Filed: 1937-02-12
Abstract: 490,374. Rotary engines; turbines. WINHUISEN, H. Feb. 12, 1937, No. 4259. [Classes 110 (ii) and 110 (iii)] A rotary engine driven by a gaseous medium consists of a rotor running in a casing submerged in an auxiliary liquid such as water, the gases flowing in a passage formed between the rotor rim and the liquid. An engine, Fig. 1, is driven by gases entering through pipe 7, expanding in the wheel 4, and exhausting through duct 8. The torque is generated by the flow of gas from inlet to exhaust. The wheel 4 may be modified by curving the blades forward in the direction of rotation, thus balancing by means of a blade action the tendency of the liquid to be thrown outwards by centrifugal force. In a further modification, Fig. 5, the ends of the blade channels 11 being provided with walls in which is a gas inlet 12, the expansion of the driving medium between the fluid and the wall assisting the rotation of the wheel. The method used for varying the quantity of liquid in the wheel and casing during starting and changing of load consists of tank 9, Fig. 4, either placed at a height or under the pressure of a point in the wheel periphery by means of a connection 14. It will be seen, Fig. 1, that as each blade channel rotates, the auxiliary liquid discharges radially inwards, moves across a chamber disposed within the blade ring, and enters another chamber radially outwards. This fact is used to control the engine by placing a throttling member 17, Fig. 4, in the passage of this fluid. The chamber within the blade ring may have guide vanes fitted to control movement of liquid. Several turbines may be placed on one shaft and more than one set of inlet and exhaust ports disposed around the wheel rim.

[Class 27.] A coin-freed meter is adapted for use with two coins of different size. The coin A, inserted through a slot 31 into the pocket 27, depresses a spring-retracted plate 32 coupled by a link 35 to a pivoted pawl 34. The size of the coin A determines whether the pawl 34 shall engage a large quantity wheel 25 or a small quantity wheel 22, coins of sizes other than the two specified ones bringing the pawl 34 to an ineffective position. The wheel 25 is mounted on a sleeve 24 carrying a pinion 23 which through gearing 16, 15, 14 rotates a crown wheel 13 of a differential 11 and imparts a multiplied number of rotations to a valveoperating spindle 10. The wheel 22 is mounted on a sleeve 21 fixed to the other crown wheel 20 of the differential 11, and imparts rotation to the spindle 10 directly through the differential. In operation, a price changer disc 28 is adjusted to the required position, the coin is inserted, and the knob 29 is turned till the coin drops through an outlet 18<a> thus rotating the wheel 25 or the wheel 22, the plate 32 is then returned by its spring and frees the pawl 34 to allow the knob to be turned back without affecting the wheels 22 or 25. Stops limit the travel of the pawl 34 and a pin 39 guides the plate 32. In a modification the pawl 34 is in the form of a plate engaging the plate 32 by pin and slot connection. Specification 348,288 is referred to.
