Title: An improved process of cleaning rusty or corroded iron
IPC: C23G5/00
Filed: 1923-01-22
Abstract: 208,103. Wandel, W. E. Dec. 11, 1922, [Convention date]. Coating-compositions. - A composition for cleaning rusty or corroded iron comprises one or more drying oils and a basic body, for instance iron oxide. The cleaning process consists in covering the metal with a layer of the composition, allowing the layer to harden sufficiently to form a coherent mass, and then stripping off the layer together with the included rust &c. The drying oil comprises one or more of the following, viz. :-raw or refined linseed oil, soya bean oil, blown fish oils, china wood oil, cod liver oil, and the like, while the basic body, instead of iron oxide, may be commercial soaps, soaps made from oils and alkali metals or their compounds, metallic soaps formed by raw oil or oil mixtures standing in contact with metal turnings with access of air or linseed foots. An efficient composition may be made by grinding half a ton of iron turnings or filings with 300 gallons of linseed oil or a mixture of linseed oil and linseed foots, preferably heated, the composition being allowed to stand some time before using. Copper or some form of oxidized copper may be used instead of iron. Another composition is made by allowing 300 gallons of oil, composed of 70 per cent raw linseed oil and 30 per cent crude cod liver oil, to remain in contact with approximately one ton of iron turnings for a fortnight or more with access of air. The Specification as open to inspection under Sect. 91 (3) (a) states also that the basic body may consist of heavy metallic soaps such as iron, copper or zinc oleates, stearate, &c. This subject-matter does not appear in the Specification as accepted.

Abstract: 1331798 Fuel injection pumps ROTO DIESEL 15 Jan 1971 [6 Aug 1970] 2073/71 Heading F1A In a fuel injection pump comprising pumping plungers C 1 , C 2  reciprocable in a rotary distributor R, the amount of fuel delivered through an axial bore a, to whichever of outlets h is in communication therewith, is varied by spilling fuel through a conduit 2 controlled by a valve 4 responsive to feed pump pressure in aline 5. During delivery the conduit 2 communicates with the bore a through one of the radial passages e which align with an inlet g during the plunger suction strokes. At start-up a spring 7 urges the valve member 4a of the valve 4 to a position closing the conduit 2. When a predetermined speed is reached the feed pump (not shown) produces sufficient pressure to open a non-return valve 6. Thereafter the pressure progressively displaces the valve member 4c to bring a groove 4c into registration with the conduit 2 and a conduit 9 leading via an adjustably loaded poppet valve 10 to a drain 11. The conduit 2 includes an enlargement 3.

Abstract: 920,674. Discharging metal melting and holding furnaces. BIRLEC-EFCO (MELTING) Ltd. Jan. 3, 1962 [Jan. 18, 1961], No. 2083/61. Class 51 (2). In a metal melting or holding furnace controlled displacement of the charge, for example into moulds, is achieved without tilting of the furnace by lowering a refractory body into the molten metal so that the required amount of metal overflows through the furnace pouring spout. Fig. 1 shows a furnace of normal construction provided with a pouring-spout 4 fed through a supply channel 4a. A refractory plug 12 so positioned as to be lowerable into the furnace is secured to a piston rod 10 of a fluid pressure jack 9 which is of the double-acting type and can control the descent of the plug into the molten metal either in a continuous action or by a stepwise motion to displace a known volume of metal from the spout of the furnace. The application of the invention to a holding furnace is shown in Fig. 2. Fresh molten metal is continuously added to a chamber 23 via a side channel, not shown. A barrier wall 22 is provided between the chamber 23 and a spout 21 and this ensures that the molten metal is always well mixed before it is discharged, by the insertion of the plug 12 through channels 27 in the bottom of the barrier wall 22 to a space 30 and thence to the spout 21. Provision is made for complete drainage of the furnace by means of a knock-out plug 31.

Abstract: 719,799. Tunnelling. BRIDGE, E. K. Jan. 28, 1953 [Jan. 28, 1952], No. 2252/52. Class 85 A method of tunnelling through earth comprises rotating a shield carrying fixed cutter blades by means of a tangentially disposed jack which bears on the end block of spirally positioned lining blocks, the shield being forced forward by thrust rollers thereon engaging with the forward facing surface of the last laid row of blocks. The shield consists of a cylindrical steel shell 1 having a forward cutting edge 3 and a rearward edge 4 formed as a two-start spiral, a hydraulic jack 5 being mounted tangentially on the shield adjacent each start. Cutter blades 6 are mounted on a frame 7 welded to the leading edge of the shield, the clay, &c., from the blades falling into compartments 8 and thence into hopper 11 which feeds it on to a conveyer belt 13. Mounted in the centre frame 7 is a steel tube 10 in which is housed a shaft carrying a fluted point 15, the shaft being angularly adjustable with respect to the tube axis so that its point serves as a steering means for the shield when the tunnel is to follow a curved course. In operation, jacks 5 which bear on the last-laid, precast concrete blocks 31 of the tunnel lining are actuated by hydraulic pressure causing the shield to rotate. At the same time thrust rollers 28 mounted on the shield and which bear on the forward facing surface of the last-laid row of blocks cause the shield to move forward. When the main jacks 5 are fully extended, auxiliary jacks are operated to hold the last block in position and the main jacks retracted. The next block is then placed in position by a hydraulically actuated arm 38 and the operation repeated. Specification 564,643 is referred to.

IPC: H01F17/02
Filed: 1926-01-27
Abstract: 268,911. Turner, G. Jan. 27, 1926. Inductances.- Multi-layer inductance coils in which the layers are spaced apart by strips permanently retained in the winding are constructed of smaller diameter by locating the second ring of spacing strips on the second coil layer and between the strips on the preceding layer, subsequent strips being either located in a similar manner or in superposed reaction to the second ring of strips. Sufficient tension may be applied to the winding to force the strips on to the former. In one arrangement, Fig. 3, the first layer 2 is applied direct on the former1 and spacing strips 3 are located thereon. The second layer 2<a> is then wound and strips 3a located thereon between the strips 3. The winding is continued with layers 2b - - and strips 3b - - some of the subsequent strips being directly positioned above those of the immediately preceding layer. In another arrangement, Fig. 4, the former has integral ribs 4 between which the strips 3a - - are located. The coils may be tapped, and two coils may be wound together or separately to form a high frequency transformer.

Abstract: 769,402. Electric selective signalling. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Jan. 13, 1955 [Jan. 26, 1954], No. 2404/54. Class 40 (1). [Also in Group XXXVI] Apparatus for telemetering an A.C. voltage corresponding to a meter reading comprises means for feeding pulses into a relay counting chain at a constant rate while charging a condenser at a constant rate, the pulses being stopped when the condenser charge is equal to the rectified A.C. voltage, as indicated by connecting the voltages to two grids of a valve which conducts when they are equal to operate a relay which cuts off the pulse source and connects the relay counting chain to a transmitting line for operating a remote counter. As shown, the A.C. voltage is fed into a transformer T, rectified at BR, and connected to the cathode of a valve V. The pulses are obtained from the 50 c.p.s. mains and squared at SL before being counted by relays A-G, while the rectified pulses charge a condenser C connected to the grid of valve V. The operation is initiated by closing a switch SK, and when the voltages on the grid and cathode of valve V are equal, the anode current energizes relay S which, at S1, stops the pulse flow and energizes a relay P to close the transmitting circuit between the relays A-G and a remote indicator. Finally a third relay R (not shown) is energized to discharge condenser C at R1, and zeroize the relays A-G at R2-R8.

Title: Process of and apparatus for recovering sulphur dioxide from refuse sulphuric acid
IPC: C01B17/58
Filed: 1934-01-25
Abstract: <PICT:0432714/III/1> Sulphur dioxide is obtained from refuse sulphuric acids such as those from the refining of mineral oil by introducing them together with carbonaceous fuels and air into a rotary furnace where the fuel and the carbon content of the refuse acids are eliminated by combustion.  Suitable fuels are coal, coke, oils, waste products such as acid sludges, spent bleaching earths &c. Pulverized coal, gas or oil may also be burnt as fuel to provide auxiliary heating.  The refuse acid and fuel may be introduced separately or in admixture, or the mixing may take place inside the furnace.  The refuse acid may be injected into the furnace either in parallel flow or in counter flow to the furnace gases. Refuse acid is introduced through an atomizer 11, which is supplied by compressed air by a pipe 12, into a rotary furnace 1. The rotary furnace is provided with a degasefying zone 3, a combustion zone 4 and a secondary combustion zone 5 and is subdivided by baffle rings 6. Liquid or solid fuel is introduced from a bunker 14 via a pipe 15. The air supply is so regulated that the cone of atomized acid extends as far as possible into the zone 4.  The injection is preferably so regulated that the outer part of the cone does not come into contact with the furnace walls or the burning fuel.  The coke which is not consumed in the rotary furnace 1 passes over the outer rim of the zone 5 into a stationary chamber 2 provided with a grate 7 where the combustion is completed.  The chamber 2 is provided with a baffle wall 8 which throws down any coke dust carried along by the gases. The sulphur dioxide containing gases finally leave through a flue 9. The rotary furnace may also be provided with turning devices or scrapers.  The sulphur dioxide gases, after if necessary being subjected to treatment in any electrical gas purifying plant may be catalytically converted into sulphuric acid without predrying. Specification 411,793 is referred to.
