Abstract: 893,658. Polishing. B. O. MORRIS Ltd. Feb. 1, 1961, No. 3748/61. Class 60. A machine for polishing articles 13, Figs. 1 arid 2, supported by a moving track 14 has a head carrying a rotary polishing element 12 which is caused to travel with each successive article through a polishing zone and to return in readiness to repeat the action on the next article. The polishing head is universally mounted on axes 22, 23 on a bracket 16 which is vertically adjustable on a column 11 by an electric motor 20 acting through a lead screw. The polishing element 12 and an electric motor 30 driving it through belt drives 31, 32, 33, 35, 36 are carried in the head on a slide 26 which is adjustable on a support plate 25 of the bracket 16 by a handoperated lead screw; the polishing element is arranged to pivot about the axis of the pulley 33 and maintained in contact with the article being polished by either gravity or a spring-actuated plunger. The column upstands from a trolley 38 which runs on rails 40, 41 disposed parallel to the track 14 and is arranged to be so actuated by a pneumatic cylinder-and-piston device 42, 43 that, as each article reaches the polishing station, the element 12 is moved into operative relation with the article and at the end of this operation is withdrawn to its initial position. The control of the pneumatic device for this purpose is by valves actuated at suitable times by the track 14. An hydraulic dash-pot 44 controls the operational speed of the pneumatic device. Adjustment of the polishing head transversely of the track is provided by mounting the column on the trolley through the intermediary of a transverselyadjustable slide 48. In the modification shown in Figs. 3 and 4 the column 11a is stationary and there are two polishing elements 12 which are arranged simultaneously to operate on a pair of adjacent articles 13 on the track 14. The drive motor 30a for the elements 12 is adjustably carried at the top of the column and is arranged to rotate through a belt drive 73 a shaft 70 carried by a bracket structure 61, 62, 64 from the column. Mounted on this shaft are two axially-slidable housings 80, 81 supported by bearings 85, 87 on axially-movable sleeves 82 which are arranged to be rotated by drive elements 74-79 on the shaft. Each housing comprises an extension 99 in which is rotatably mounted a shaft 96 which is driven through a gear connection 94a, 95a with its respective sleeve and has clamped on its outer end a polishing element 12. The necessary reciprocating movements of the elements 12 are effected by a pneumatic cylinder-and-piston device 42, 43 operating on the respective casings. Spring-loaded plungers 100 act on the extensions 99 to urge the elements 12 into contact with the articles 13. Corrugated sleeves 103, 107, 108 protect the bearings within the casings.

Title: Improvements in welding transformers
IPC: H01F38/08
Filed: 1943-03-10
Abstract: 564,213. Transformers. WILSON WELDER & METALS CO., Inc. March 10, 1943, No. 3907. Convention date, Sept. 10, 1942. [Classes 38 (ii) and 38 (iv)] A welding transformer has two cores 14, 15 carrying two primary windings 16, 17 and a common secondary winding 30; the primary winding 16 is alone in circuit till an arc is struck when the other winding 17 is automatically introduced in parallel with it by a switch 19, 20, 25 whose operating coil 28 is in series with auxiliary windings 33, 34. The arrangement prevents a dangerously-high open circuit voltage and when the second primary 17. is included in circuit, the voltage across the secondary windings is not appreciably increased owing to the arc voltage drop of some 30 volts. On open circuit, no current flows through coils 33, 30 since they oppose each other, but when the arc is struck they both supply it. A thermostat 35 prevents operation of the switch 19, 20, 25 if the temperature is excessive. By connecting condensers 42 across the winding 17 that is disconnected during idling, there is no power factor correction during idling periods, and the connection increases the available current when the arc is first struck.

Patent GB-808901-A (GB)
Title: A new or improved method of and equipment for cleansing surfaces of oily deposits
IPC: B08B9/093
Filed: 1954-02-11
Abstract: A method of removing animal, vegetable or mineral oily deposits from tanks by means of a cleansing liquid and then recovering the oil therefrom comprises passing the used cleansing liquid and the removed oily deposits mixed therewith to gravitational separating means in which the oil is allowed to stratify upwards and sediment is settled, mechanically raising the settled sediments up a conduit to a discharge point, and recirculating the cleansing liquid for further use.  The separating means is a tank 1 having at its lower end an archimedian screw 35 for withdrawing the bottom sediments along a tube 30.  A second tube 31, arranged as shown, uses similar means, 41, 37, for mechanically raising the sediments to a discharge port 44.  The tube 31 may be turned about the axis of the tube 30 to vary the height to which the sediment is raised.  Agitating members 33, at the bottom of the tank 1, are rotated to keep the sediments <PICT:0808901/III/1> well mixed.  The cleansing liquid that remains is pumped through a cleansing liquid container 2, over heating coils 7, to a pipe 8 for re-use on the surfaces to be cleaned, whereafter the resulting mixture of cleansing liquid and removed deposits flows back to the tank 1 through a pipe 11 passing through the heated container 2. The pipe 11 discharges into troughs 14 below baffles 15 minimizing disturbances in the tank 1.  An upper heating coil 20 is arranged just above the interfacial level 19 between the floating body of oil that separates out from the mixture and the lower, denser, body of liquid.  The coil 20 heats the separated oil which is drawn off through an overflow 18.  The level 19 is fixed by floats 22, 23 controlling the rate of flow of the cleansing liquid to or from a reserve make-up tank connected to the apparatus by a pipe 24. If the apparatus is to be ship-borne a riser 9 is added to the tank 2 to balance any hydrostatic pressure set up in the tank 1 on rolling. The cleansing liquid may be water or an aqueous detergent liquid containing a cationic, anionic, or non-ionic surfactant, and it may also contain the following compounds:-sodium silicates; sodium carbonate, anhydrous or crystallized; sodium sesquicarbonate; sodium phosphates; sodium hydroxide; sodium borates; sodium salts of certain organic acids such as acetic acid; sodium sulphate; sodium nitrate; sodium nitrite; sodium chloride; potassium permanganate; calcium hypochlorite; ammonium sulphate.  The neutral salts increase the density of the liquid so that the removed oily deposits may stratify in the separating means.  Potassium permanganate or calcium hypochlorite may be used in the cleansing of petrol tanks to neutralize deposits of lead compounds.  In one example, the detergent mixture is composed of sodium metasilicate, anhydrous sodium carbonate and a sodium alkyl sulphate.  Specifications 742,844, [Group XVII], and 808,902 are referred to.

Abstract: 197,728. Moore, S., and Hunter, C. Feb. 15, 1922. Float valves; valves actuated by rotary motors; clockwork and magnetically actuated valves.-In operating water-gas producers in which secondary air is supplied for the combustion of gases for heating a coal gas retort, the volume of secondary air is automatically controlled by devices which may be dependent upon the primary air supply so that the secondary air supply is gradually increased during the " blow " period. In Fig. 1 the secondary air supply pipe A is provided with a valve C connected to a lever D to which is attached a rod H carrying a float R working in a chamber S, and a plunger T<1>. Water is supplied by an inlet S<1> and flows through outlets T<2>, S<2> and an overflow S<4>. To open valve C, valve S' on pipe S<2> is closed, water rises in the chamber S, raising the float R, rod H and plunger T<1> until the latter closes the outlet T<2>, whereupon the water rises more rapidly and causes valve C more rapidly to open. Valve C is closed by opening valve S<3> and emptying chamber S. The valve S<3> may be interconnected with the valve controlling either the primary air blast or the steam to the producer. In a modification, a ball float in a cistern may operate the air valve in a similar manner. In Fig. 4 an air turbine L may operate a rack J through gear wheels N<1> or a clockwork motor may replace the turbine, the rack pinion having teeth over only a portion of its periphery, so that when the pinion moves out of engagement with the rack the valve closes. In another modification, the valve is operated by a solenoid in series with a resistance so arranged that the resistance is diminished when the valve is being opened, causing the rate of opening to be increased. Specification 168,951, [Class 55 (i), Coking &c.] is referred to.
