Title: Process for the utilisation of the quenching vapours periodically resulting from the quenching of glowing coke in a pressure vessel
IPC: C10B39/04
Filed: 1929-06-25
Abstract: 328,852. Bamag-Meguin Akt.-Ges., and Heller, O. June 25, 1929. Cooling discharged material. - The vapours generated by the quenching of coke in a closed chamber 6, Fig. 1, are led through a pipe 11 into water in an accumulator 2, from which the uncondensable gases and steam are led off separately through pipes 18, 20. The gases pass off through a loaded valve 19 in the pipe 18, and then a valve 21 is opened to reduce the pressure in the accumulator and to allow the steam thus regenerated to pass off through the pipe 20. Quenching water is supplied to a sprayer 8 by a pump 4 drawing from the accumulator or from an open water heater 3, into which the residual gases and steam from the chamber 6 are discharged through a pipe 15, a valve 10 in the pipe being then open and a valve 9 in the pipe 11 closed. The gases and steam from the accumulator may be passed in turn through hot coke in a shaft. The water supply to the accumulator 2, Fig. 5, is preheated first in a closed chamber 3, receiving residual vapours from the quenching chamber 6 through a pipe 55. and then in a direct contact heater 34, in which the water flowing over plates 34<a> is heated by the gases passing from the accumulator through a pipe 37 into the upper part of the heater 3. The gases escape through a loaded valve 45 and a trap 46. A valve 48 in the steam outlet pipe 49 is opened, when the pressure falls, by an electromotor 96 controlled by a switch 100 operated by electromagnets supplied with current directed according to the position of the needle of a pressure gauge 72 on the quenching chamber. Similarly, valves 36, 38 in the pipes between the heater 3 and the accumulater are closed, and a valve 43 in a bye-pass 42 on the gas outlet pipe 44 is opened, when the pressure falls, by an electromotor 76 controlled by a pressure gauge 73 on the accumulator. When the pressure rises to a certain point, the valves 36, 38 are automatically opened and the steam valve 48 and the valve 43 are closed. The steam is passed through a second accumulator 50, which is supplied with water purifying solutions from a chamber 65. In further modifications, the vapours generated by the quenching of successive loads of coke are passed into two accumulators so connected in parallel as to give a continuous and separate outflow of steam and gases.

Title: Tufted pile fabric
IPC: D04H1/06
Filed: 1970-04-24
Abstract: 1,249,756. Finishing fabrics; non-woven fabrics; pile fabrics. BIGELOW-SANFORD Inc. 24 April, 1970 [14 Aug., 1969], No. 19823/70. Headings D1K, D1R and D1S. A tufted pile fabric is made by (a) providing a backing fabric 4 comprising a needled web of intermixed textile fibres the majority of which are of a heat-shrinkable synthetic thermoplastic material, the exposed fibres on at least one exterior surface being bonded together, the fabric 4 having a plurality of spaced pile yarns 3 extending therethrough at spaced points along each yarn to provide a plurality of pile elements upstanding in rows from one face of the fabric 4, and (b) shrinking the fabric 4 by continuously moving itin a direction lengthwise of the pile yarns 3 through a heating zone 26 to heat the shrinkable fibres to a temperature above their shrinking temperature but not above their fusion temperature, while substantially inhibiting lengthwise shrinkage of the fabric 4 and controlling the shrinkage of the fabric 4 in the transverse direction. Preferably, the backing fabric 4 is formed by the distribution of fibres, e.g. polypropylene fibres, by garnets in one or more superimposed layers on a carrier, e.g. a low-count cotton cheese cloth, preferably, with the fibres extending predominantly transversely of the web, and this assembly is needled with barbed needles to force some of the fibres through the open mesh of the cheesecloth. After needling, the fibres on one or both exterior surfaces are heat bonded by contact with rollers, e.g. heated to 325-350F. The fibres of the backing may be polypropylene or a mixture of polypropylene with nylon, rayon or acrylic fibres, or polyesters, or mixtures thereof. In place of cheesecloth, there may be provided a layer of longitudinally extending polyester filaments 64, Fig. 3, threads or yarns or a layer of an oriented plastics film, e.g. polypropylene, which is fibrillated by the needling operation. The pile yams 3 are formed on the fabric 4 by a tufting machine having reciprocating needles. As shown in Fig. 1, a tufted pile carpet fabric 2, produced as above-described, is supplied from a roll 6 having pins or spikes 7 thereon to prevent slippage of the fabric and passes over a guide roll 10. The opposite edges of the fabric 2 are engaged by pins 16 on tenter chains 12, 14, rotary brushes 22, 24 being provided to impale the fabric on the pins. The chains 12, 14 guide the fabric through a heating chamber 26 heated by steam circulating coils (28), Fig. 2 (not shown), e.g. to a temperature of 315-320F, and constrain each of the edges to move along a fixed line inclined towards the middle of the fabric 2. Guide rolls 18, 20, 32, 34, 36, 38, 40, 42, 48, 52, 50, 54 for the chains 12, 14 are provided. Adjacent the exit of the chamber 26, the fabric 2 is engaged by a spiked roll 56 and is re-wound on a roll 60.

Patent GB-799264-A (GB)
Title: Improved lard shortening
IPC: C11C3/10
Filed: 1955-07-08
Abstract: A glyceride fat mixture suitable for use as a shortening and derived principally from lard has a polyunsaturates number below 18 (i.e. per cent linoleic acid or equivalent plus ten times per cent of fatty acids more unsaturated than linoleic) and, when warmed from 40-103 DEG  F., exhibits a decrease in Solids Content Index value of less than 20 units.  The product is obtained by partially hydrogenating to a combined linoleic acid content of less than 10 per cent those glycerides obtained from lard by the interesterification process of Specification 799,263.  Variations in the product may be obtained by blending the lard after interesterification with a lesser proportion of other animal or vegetable fats or oils, many of which are specified and which may be, if desired, already partly or fully hydrogenated.  Preferably the shortening is derived at least 80 per cent from lard and 3-20 per cent from tallow.  The products of the process all lie to the left-hand side of the diagonal lines of Figs. 1 and 2. Specifications 574,807 and 590,737 also are referred to. <PICT:0799264/III/1> <PICT:0799264/III/2>
Patent GB-635689-A (GB)
Title: Improved method of preparing lubricating oils
IPC: C10G50/02
Filed: 1946-07-03
Abstract: Lubricating oils are synthesized by dehydrating isoamyl alcohol over activated alumina at 330-370 DEG  C., polymerizing the mixture of amylenes produced, which comprise at least 50 per cent of isopropylethylene, in the presence of from 25-50 per cent of its volume of a volatile solvent and of a Friedel Crafts' catalyst at -5 DEG  to -10 DEG  C., and washing and filtering the polymer.  The product of the dehydration stage is rectified to remove water and unchanged alcohol and give a mixture of amylenes containing not less than 50 per cent isopropylethylene.  This may be added to a mixture of the solvent, e.g. petroleum ether, and about 10 per cent aluminium chloride.  Alternatively, the amylene isomers in the mixture may be added separately, the temperature being maintained at -10 DEG  to -5 DEG  C.  The viscosity and iodine number of the product is controlled by varying the temperature and the proportion of solvent, and the time of contact.  After separating the catalyst, the liquid is washed with dilute acid and water, heated up to 160 DEG  C. to remove the solvent and destroy chlorinated products, and filtered.  An additional treatment with activated earth at 110-120 DEG  C. may be effected.  Boron fluoride or chlorides of iron, bismuth or antimony may replace aluminium chloride.

Title: Process for the production of moulded articles from cellulose acetate
IPC: B29C43/00
Filed: 1920-07-09
Abstract: 147,904. Mond, A. L., (Cellon-Werke, Dr. A. Eichengr³n). July 9, 1920. Plastic compositions containing cellulose acetate.- Relates to the production of moulded articles from cellulose acetate and consists in subjecting the material in a finely divided state, preperably in the presence of very small amounts of lowboiling or volatile substances, to a high pressure at a temperature approaching the decomposition point and allowing to cool under pressure. A metallic die-holder a is used having a bore b for the insertion of a thermometer. The operation may be carried out at a lower temperature and pressure by adding 2-5 per cent of water, alcohol &c. or solid substances such as naphthalene or camphor. Preferably the material obtained by a first pressure is disintegrated and subjected to a second pressing-operation. In this case, the cooling under pressure may be omitted by providing the mould with channels, nozzles, or slots of small diameter, through which the hot material is forced under pressure in the form of filaments or ribbons. The disintegrated material may be mixed with large quantities of mineral powders, e.g. 2 to 5 times the amount of cellulose acetate, before applying the final pressure. The material may be moulded with inlays of wood, ebonite, ernolite, &c.

IPC: C22B5/16
Filed: 1950-08-11
Abstract: 700,174. Distilling metals. SOC. ANON. ASTRAL. Aug. 11, 1950 [Aug. 19, 1949; July 21, 1950], No 19988/50. Class 82 (1) A process for the continuous condensation of metallic vapour in the liquid state consists in maintaining a pressure at least five times greater than that of the metal in a condensing chamber, subjecting a constantly cooled condenser to direct radiation from a reducing or distilling chamber the metal first condensing as a solid and the heat supplied by the metal vapour increasing the temperature of the surface of the metal layer above that of the triple point of the metal, the metal then being condensed and collected in the liquid state. As shown, a condensing chamber b has vertically supported therein a water-cooled condenser d arranged to face an outlet e from a distilling or reducing furnace. A pipe b<SP>1</SP> leads from a preferably water-cooled point, above the condenser and on the opposite side to the outlet e to a vacuum pump which maintains a pressure of 5 to 10 times that of the triple point of the metal within the chamber b. The liquid metal falls by gravity from the condenser and is collected in a crucible f, the temperature of which may be kept constant by a thermostatically controlled electric heating coil f<SP>3</SP>. The condenser may have a concave face opposite the outlet e, and may be provided with fins d<SP>4</SP> attached to but thermally insulated from the cooling water pipes d<SP>1</SP> to act as a thermal screern, the condenser, pipes, and fins being removable for cleaning. A deflector may be fitted to cause the vapour to pass below the condenser to the outlet b<SP>4</SP>.

Abstract: 812,716. Laminating apparatus. CULPITT, P. J. May 21, 1957 [June 28, 1956], No. 20015/56. Class 140. [Also in Groups VII and XV] A laminated flag or artificial leaf with its stem is made by inserting a part of the stem, e.g. of wire, between a main strip and a gummed backing strip, e.g. of paper, cloth or metal foil, pressing the strips together to cause them to adhere and to secure the stem between them and then cutting the required shape of flag or leaf from the combined strips. The pressing operation may also include the step of embossing the strips to produce a pattern such as the veins of a leaf. Apparatus for carrying out the process comprises a base 1, Fig. 1, on which is mounted a vertically movable press member 2 carrying a veining head 3 and a cutting head 4. A strip 8, e.g. of paper, is fed first under the head 3 and then under the head 4, and a backing strip 9 gummed on one side and fed from a reel past a damping roller, is fed between the strip 8 and the base 1. Wire 12 is fed through an internally coned collar 11, Figs. 1, 4, under veining head 3 and between the strips 8, 9. When the press member 2 is moved down, the vein pattern of the head 3 is impressed on the strips 8, 9 which at the same time are adhered together to secure the wire between them. During this operation the wire 12 is located by a vertical slotted bar 13 carried by the press member 2. Forwardly of the veining head 3, the press member 2 carries a punch 14 which cuts the wire 12. After raising the member 2, the strips are advanced so that the veined blank with the wire attached thereto is brought under the cutting head 4 which cuts the required leaf shape from the blank when the press member 2 is again lowered.

Abstract: 916,692. Jet propulsion nozzles. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 11, 1959 [June 19, 1958], No. 20072/59. Class 110 (3). [Also in Group XXXIII] Means for controlling the cross-sectional area (and direction) of a propulsive jet issuing from the end section of a nozzle comprises an enlargement of the nozzle wall immediately downstream of the end section and surrounding the jet, closure means downstrean of the end section and defining a cavity surrounding the jet, radial partitions in the cavity defining chambers open inwardly towards the jet, and means for supplying fluid under pressure individually to the chambers so that the jet is bounded by fluid isobar surfaces forming an extension of the nozzle wall, the pressure in the chambers being capable of variation from one chamber to another. Fig. 1b is a half-section of a nozzle, the closure means of a chamber 4 comprising a radially movable shutter 15a and a fluid screen 11a, the fluid for which is led through valve 14 and the interior of shutter 15a to cool the shutter, from a tapping point upstream in the nozzle. Fluid is supplied to chamber 4 through valve 7. Four such chambers surround the jet, and the pressure therein is variable by valves 7 to control the cross-section of the jet, valves 14 being controlled conjointly. Shutters 15a or fluid screens 11a may be used alone. The four partitions (not shown) which separate adjacent chambers may be movable in their radial planes, either bodily or by hinging about axes near the nozzle throat. In Fig. 6, the cross-section of the circular nozzle throat is variable by pivoting flaps 27 (two only shown), adjacent flaps overlapping. Alternatively, where the throat is upstream of the chambers as in Fig. 1b, the flaps 27 may be parts of the nozzle wall extending downstream from pivotal axes just upstream of the throat, Fig. 5 (not shown). Alternatively, the throat area may be varied by radially inwardly movable members, Fig. 5a (not shown). The fluid for the chambers, and for any fluid screens, may be obtained from the compressor of a gas turbine engine or from the fuel supply of a rocket engine, or may be a fluid other than an engine working fluid. In Fig. 9, rocket engine fuel is tapped through duct 32 to flow through the wall of the nozzle throat before being led to chamber 4 through duct 6 or before forming a screen 11 (the fuel then being in the vapour phase) fed by duct 13. Where a shutter is used instead of a fluid screen, duct 6 may discharge over the upstream face of the shutter to cool it.
