IPC: A23C3/03
Filed: 1925-07-22
Abstract: 237,899. Armitage, F. L. Aug. 2, 1924, [Convention date]. Sterilizing milk and cream.-A process for pasteurizing and deodorizing milk or cream comprises boiling under reduced pressure and subsequent complete or partial cooling within one container, the heating and cooling means being solely external. As shown in the Figure, the container 1 comprises two parts 2, 3 clamped together at 10, the part 3 being hemispherical and having double walls enclosing a heating and cooling space 11. A three-way cock 34 permits connection of the container 1 with the atmosphere and with an ejector pump 54 respectively. In use, the container, preferably partially exhausted, is filled with cream from a vat 63 by means of pipes 64, 33 controlled bv a cock 62. Connection is then made to atmosphere and steam is passed through the space 11 by a pipe 48, escaping through a pipe 13, 60. The cream is thus raised to a predetermined temperature and is maintained thereat by a thermostat 45 controlling a valve 47 which regulates the steam supply. Deodorization is then effected by partly exhausting the vessel 1. The passage of foam into the exhausting pipe 35 is prevented by the provision of an annular watercooled baffle 39. The ebullition of the cream keeps it sufficiently agitated. Deposition of solid matter, however, is prevented by scrapers 14, 15 revolving on a spindle 19 driven by gearing 22, 23 from a pulley 20. After boiling for a predetermined time the steam is cut off and cold water or brine is admitted into the space 11. The vacuum is then broken and the cream drawn off through the pipe 33 and pumped, by a pump 67, into a vat 69 for further cooling or other treatment. The whole operation is stated to be completed in about thirty-five minutes, boiling temperatures of from 165‹ to 175‹ F. being preferably used. The container 1 is provided with a pressure gauge 37, a low-pressure safety valve 38, a thermometer 32 and glass-covered inspection ports 42, 43, the cover of the port 43 being cleaned by a water spray from a glass pipe 44.

In an auxiliary engine for a pedal cycle including a cylinder 101, piston 128, crankshaft 103, two crankshaft bearings 105, 107, a driving roller 108 adapted to transmit power from the engine to a cycle tyre when arranged in contact therewith, and a flywheel or flywheel magneto 104, entirely disposed on one side of the axis of the cylinder, the roller 108 is arranged between the flywheel or flywheel magneto 104 and the cylinder 101 and being of tubular form substantially encloses one of the bearings 107, the latter being so mounted that in operation almost the whole reaction from the tyre is transmitted therethrough. The crankcase 102, which houses the bearing 105 for the crankshaft 103, has extending from one side thereof a channel section bracket 112, also acting as a shield for the roller 108, and a sleeve 106, the latter carrying the second crankshaft bearing 107. Outwardly of the second bearing 107, the crankshaft has secured thereto the steel or carborundum driving roller 108 which may incorporate axial grooves or have a plain surface; the roller 108 also embodies a central circumferential groove to afford a channel for road grit picked up by the tyre. The outer end of bracket 112 carries a disc 113 with an opening therethrough for the crankshaft, which disc supports the frame 117, 118 of the flywheel magneto 104 that is enclosed within a detachable casing 119. The open end of the crankcase 102 is closed by a screwed plug 121 the adjustment of which or the use of plugs of different lengths enables the compression in the crankcase to be varied. The fuel, which contains a proportion of lubricant, is fed from a carburetter, not shown, compressed in the crankcase and serves to lubricate the first bearing 105 whilst the space 124 between the sleeve 106 and the crankshaft is packed with grease, sealing rings 125 and 126 being provided at either end of the space. The engine, which may be mounted on the rear wheel of a bicycle with.the cylinder 101 to one side thereof and extending downwardly, may operate on a two or four stroke cycle. Petrol or diesel oil may be used as fuel and in the latter case, the dynamo and sparking plug (not sh)wn) are dispensed with, the dynamo being replaced by a flywheel and a fuel pump. The soarkin. plug is normally mounted at right angles to the cylinder axis and at one side of the cylinder he.d with the electrodes in a recess to avoid being fouled by oil collecting in the cylinder head when the engine operates in the inverted position. The engine may be separately lubricated instead of depending upon lubricant added to the fuel. A decompressor valve may be fitted centrally in the cylinder head. Specification 682,241, [Group XXXI], is referred to.
Patent GB-1216130-A (GB)
Title: Determination of the quantity of slag in metallurgical multi-slag processes
IPC: C21C5/30
Filed: 1968-04-23
Abstract: 1,216,130. Slag determination in oxygen steelmaking. SALZGITTER HUTTENWERK A.G. April 23, 1968 [April 28, 1967], No.19173/68. Heading C7D. [Also in Division G1] The quantity of slag present at various stages of metallurgical multi-slag process is measured by the use of a radioative tracer. The method can be used during the LDAC multi-slag process in which phosphorus-rich pig iron is refined by blowing pure oxygen mixed with lime dust into the surface of the melt through a water-cooled lance. The tracer used may be Lanthanum 140, Barium 140, or Yttrium 90, having a half life of 61 hours. All of these disperse quantitatively through the slag phase of the melt. The method is described with reference to the first and second melts of such a multi-slag process, each melt comprising first and second blow periods. In the first melt, the approximate quantity of slag in the converter after removal of slag at the end of the first blow period, is known and thus it is known approximately how much will be present at the end of the second blow period. This gives a guide as to how much radioactive isotope to add at the beginning of the second blow period. During this period the isotope disperses thoroughly in the slag and at the end of the period a sample is taken, the radioactivity of a predetermined surface area is detected to obtain a pulse rate measurement. From a calibration curve, the concentration or amount of isotope in the sample is read off and using this and the value of the original isotope concentration added, the weight of slag in the converter is calculated. Thus at the beginning of the second melt the slag quantity is known accurately. In this melt, a known quantity of slag is drawn off at the end of the first blow period and bearing in mind that some isotope is still left in the slag remaining and that some decay of this isotope has occurred a suitable further quantity of isotope is added at the beginning of the second blow period. Sampling is repeated as before at the end of this period.

Abstract: 275,602. Wisner, C. B. Aug. 7, 1926, [Convention date]. Coking processes.-Coal is distilled in a two stage process, the first stage consisting in heating the coal with access of air to retain a sufficient hydrocarbon content to allow the charge to take the form of balls, and the second stage consisting of carbonizing the resultant mass at a temperature sufficient only to remove condensible hydrocarbons. The fuel is ground to pass a screen having three-eights inch openings and is subjected in a rotary retort for from 15 to 45 minutes to heating just below the temperature at which hydrocarbon vapours are evolved while air, which may be preheated, is passed over the fuel, oneeighth of a cubic foot to five cubic feet of air per pound of fuel being employed. The preheated fuel is then heated from 750‹ to 900' F. until it has a volatile content of about 12 per cent, and during its passage through a second rotary retort is rolled into balls of varying sizes having the properties required for domestic and steam fuel purposes. A strongly coking coal may be mixed with a non-coking coal, or pitch may be used as a binder. A suitable apparatus comprises two rotary retorts 1, 1<1> mounted on rollers 6, 6<1> and heated by a furnace 12 provided with gas burners 12<1> the hot gases passing by a flue 14 to the annular space 4<1> between the cylinders 2<1>, 3<1> of the lower retort and from the latter by a pipe 15 into the annular space 4 of retort 1, returning by a pipe 16 to a reheating flue 17 in the furnace.
