Title: Improvements in regenerative heat exchange apparatus for gaseous fluids
IPC: F28D19/00
Filed: 1955-12-05
Abstract: 823,937. Gas-turbine plant. FALLON, J. T. Dec. 5, 1956 [Dec. 5, 1955; March 27, 1956], Nos. 34810/55 and 9527/56. Class 110 (3). [Also in Group XIII] In a gas-turbine plant comprising a compressor feeding air to a turbine assembly driving the compressor and supplying external power, the compressed-air is heated prior to use in the turbine assembly in a non-mixing regenerative heat exchanger (see Group XIII) by hot gas from an external source. Air aspirated through an inlet 10 is compressed in a compressor 12 and then discharged through the volute 14 and pipe 32 to one 28 of a pair of regenerative heat exchangers 26, 28. The heated air passes to the turbine inlet through a pipe 34. Combustion products from a combustion chamber 24 are supplied to a regenerator 28 by a pipe 30 and exhausted therefrom by a blower 38 through a pipe 36. The regenerators 26, 28 are intermittently moved or oscillated through 180 degrees to connect each regenerator alternately with the pipes 30, 36 and the pipes 32, 34 During the periods of rotation the open ends of pipes 32, 34, 36 are closed and the by-pass pipes 46, 48 are in circuit. To maintain the heat supply to the compressedair when it passes through the by-pass 48, a thermal storage chamber containing heatretentive elements is disposed in the pipe 34. To enable the regenerator assembly to rotate, clearances are provided between the open ends of pipes 30, 36, 32, 34 and the regenerators. The clearances at the ends of pipes 30, 36 need not be sealed since the blower 38 will cause air leakage at these points which will merely lower the combustion gas temperatures.

Abstract: 898,680. Blow-moulding hollow plastic articles. OWENS-ILLINOIS GLASS CO. Nov. 1, 1958, No. 35129/58. Class 87(2). In apparatus for blow moulding thermoplastic material a series of blow moulds 13 are carried by a continuously rotating table 12, and as each mould comes into position beneath a downwardly directed extrusion nozzle 56 to receive a length A of tubular extrusion therefrom the nozzle interlocks with the mould and moves with it whilst the mould is closed about the extrusion, which is then severed by a knife 85. The column 15 carrying the table 12 is driven by gears 18 from a motor (not shown) and upstanding therefrom is a column member 75 to which are secured blocks 76. The nozzle 56 extends from a rotary part of the extrusion head 11 which carries a pneumatic motor 70 controlled by a valve 81 actuated by a cam 80 on the drive shaft of the table 12. When the valve 81 is opened the motor 70 projects a block 72 downwardly so that it is engaged by one of the blocks 76. The nozzle 56 is then carried around with the table 12 until the valve 81 is closed after the length A has been severed by the knife 85. The moulds 13 are opened and closed by pneumatic motors 23 controlled by valves 25 carried by the table 12 and each actuated by a stationary cam (not shown). Co-operating with each blowing mould 13 is a neck forming plunger 40, Fig. 8, operated by a piston 41 of an air motor 42 controlled by a valve 44 actuated by a stationary cam 45. When the valve member 46 is raised by the cam 45 air under pressure is admitted to the motor 42 to raise the piston 41 to seat the plunger 40 in its operative position, and to permit air to pass from a branch line 27a to a groove 41a and passage 40a in the piston to blow the tube A in the mould 13. In an alternative embodiment the neck of the hollow article is formed in a separate mould.

Title: Process for the treatment of mixtures of urea, water, carbon dioxide and ammonia, produced in the course of the manufacture of urea
IPC: C07C273/04
Filed: 1938-12-02
Abstract: 509,987. Drying gaseous mixtures. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES, ALAIS, FROGES, ET CAMARGUE. Dec. 2, 1938, No. 35167. Convention date, Jan. 6. [Class 34 (i)] [Also in Group IV] Mixtures of urea,.water, carbon dioxide, and ammonia produced in the manufacture of urea in an autoclave, are treated under pressure in a rectifying column to reduce their water content as far as possible, part of the concentrated urea solution flowing from the bottom of that column being lifted to the top thereof by pumps or, if desired, by utilizing an injector or mixing cone, actuated by the reaction mixture flowing under pressure from the urea synthesis autoclave. In this way blockage of the column or the formation of deposits therein is minimized, and, especially when using a column fitted with rings, better contact is obtained between gases and liquid so that the water concentration of the gases leaving the rectifying column approaches closer to theoretical figures. Carbon dioxide and ammonia from other sources may be absorbed in water and the resulting solution redistilled in an auxiliary column under a pressure equal to or greater than that of the rectifying column, the wet gases from the auxiliary column then being introduced at the bottom-of the rectifying column to be dehydrated together with the gases from the urea synthesis. In this way fresh carbon dioxide and ammonia may be introduced into the urea circuit to replace that converted into urea. The gas mixture dehydrated according to the invention may be used to prepare a suspension of carbamate or carbonate of ammonia in an inert liquid, the suspension then being heated to 160-200‹ C. and pumped back into the autoclave at 100- 250 atmospheres pressure.

Abstract: 879,253. Circuits employing transfluxors. HUGHES AIRCRAFT CO. July 23, 1958 [Aug. 2, 1957], No. 36048/60. Divided out of 878,156. Class 40 (9). A trigger unit, which produces a continuous train of large-amplitude pulses in one state and a continuous train of small-amplitude pulses in another state, comprises two tranfluxors 24 and 26. With the windings shown in Fig. 1, application of drive produces the state shown as ZERO in Fig. 3. A subsequent input produces the ONE state while if this is followed by a prime pulse the PRIME state is produced. The PRIME state is reset to ZERO by a drive pulse. Should an input not precede a prime pulse the ZERO state is not disturbed. An output winding induces a small voltage if drive is applied to the ZERO state but induces a large signal if drive switches PRIME to ZERO. As shown in Fig. 4 a trigger unit has the output of transfluxor 24 coupled as an input to transfluxor 26 and vice versa. Drive to transfluxor 24 coincides with the input period to transfluxor 26. Should a ONE state be injected into transfluxor 24 over a winding 36 it is read out after priming and driving to inject a ONE state into transfluxor 26 from which it is read out and re-injected back into 24. While the ONE state circulates, drive to transfluxor 26 produces large output in winding 65. Circulation of a ONE state is inhibited by a pulse on winding 38 which neutralizes feedback in winding 64 thus leaving both transfluxors in ZERO states and only small output in winding 65. It is stated that the cores may comprise thin magnetic films. Specification 879,252 also is referred to.

Title: Improvements relating to the production of motor gasoline
IPC: C10G59/04
Filed: 1955-12-19
Abstract: High octane gasolines of adequate volatility are produced by the thermal reforming of a mixture of a light straight-run gasoline boiling below about 100-120 DEG  C. and a platinum reformate; the product should have a Research octane number (clear) of at least 90 and a volatility of at least 35 per cent by volume recovered at 100 DEG  C.  The feedstock to the platinum reforming process may boil within the range 80-200 DEG  C. and is processed to give a platformate having an octane number (research clear) of at least 90. The light straight run gasoline may be the light ends of the crude petroleum feedstock to the "platforming" (e.g. C5-90 DEG  C.).  The thermal reforming may be conducted at 1000-1200 DEG  F. and 200-1200 p.s.i.g. to give a conversion of 5-25 weight per cent C3 and lighter. In an example, a straight-run Kuwait naphtha (90-190 DEG  C.) was platformed to give in 75 weight per cent yield a gasoline of 95 research octane number and a volatility of 44 vol. per cent evaporated at 100 DEG  C.  This was mixed with a Kuwait straight-run light gasoline (C5-90 DEG  C.) in the proportion 70/30 by volume platformate-gasoline.  The mixture was thermally reformed at 1060 DEG F. and 750 p.s.i.g. to a conversion of 18 weight per cent C3 and lighter.  The resultant gasoline had a research octane number of 100 clear and a volatility of 47 vol. per cent evaporated at 100 DEG  C.

Title: Heat treatment process
IPC: B29B13/00
Filed: 1964-09-04
Abstract: The ultimate elongation of cross-linked crystalline polymers is improved by heating the cross-linked crystalline polymer, which may be in the form of a shaped article, first to a temperature above its crystalline melting temperature and then rapidly cooling to a temperature below its crystalline melting temperature. Polymers mentioned which may be heat treated are polyethylene, polypropylene, polyvinylidene fluoride, polyamides such as polyhexamethylene adipamide and polyesters such as polyethylene terephthalate.  These polymers may be cross-linked by any suitable method.  Crystalline polymers which exhibit elastomeric properties at or above their crystalline melting temperatures, e.g. polytetrafluoroethylene, may also be treated according to the invention although they are not cross-linked. The polymers to be treated may be foamed and they may contain reinforcing fillers.  In the examples: (1) Samples of polyethylene alone, polyethylene containing finely-divided silica and polyethylene containing antimony trioxide were separately milled, pressed into slabs and then irradiated to cross-link the polyethylene and then heated in an oven, the last four minutes being at 150 DEG C., and then quenched in an ice-bath at 0 DEG  to 4 DEG  C. (2) Samples of polyethylene, a blowing agent and an antioxidant are blended and then extruded as a foamed wire insulation.  The samples are irradiated and then heated at 375 DEG  F. for 30 seconds and then quenched in water at 10 DEG  to 15 DEG  C. (3) Polyethylene containing carbon black was formed into slabs, irradiated and then heat-treated.
