Title: Improvements in refrigerating systems
IPC: F25B1/08
Filed: 1938-10-26
Abstract: 521,754. Refrigerating. STATOR CORPORATION. Oct. 26, 1938, Nos. 30979 and 30980. Convention dates, Oct. 27, 1937, and May 11, 1938. [Class 29] Vacuum systems.-In. systems in which the vapour of aqueous refrigerant liquid is entrained and compressed by mercury vapour as set forth in Specification 292,812, [Class 29], the formation of mercury sludge on the low pressure side of the system is reduced by adding ethylene diamine or morpholine to the refrigerant or by heating the vapour delivery tube of the second stage aspirator, and any sludge formed is separated into mercury and refrigerant by pressure or suction. The system described comprises a heated mercury vapour generator 1 which supplies first and second stage aspirators 5a, 5b. The first stage is connected to the refrigerant evaporator 11 by a vapour pipe 8 and discharges into a chamber 7 from which liquid mercury particles drain through a conduit 49. Mercury vapour is condensed in a finned tube 12 drained at 14, while the other vapour after being cooled in a finned pipe 16 passes to the second stage aspirator, which discharges into a chamber 22 and tube 25. Uncondensed vapour passes into a tube 29 provided with internal baffles and heated by conduction through a plate 13 on the hot mercury vapour pipe 5. As the result of this heating effect mercury particles coalesce and flow down to a drain pipe 27. The refrigerant vapour passes on to the condenser proper 30 and the condensate flows through a pipe 34 and a liquid seal 42, 43, 44 into the evaporator. A sludge chamber 50 is connected to the wide bore pipe 44 from the bottom of the evaporator and through a vapour pipe 70 with the top of the evaporator, and is connected through a seal 53 with the drain conduits 49, 51 of the aspirators, from which mercury spills over into a tube 55 leading to the mercury vapour generator. Should refrigerant freeze in the upper part of conduit 44, the aspirator withdraws vapour mainly from the sludge chamber through conduits 70, 8, and the evaporator gradually warms up and melts the ice. Uncondensed gases in the refrigerarit condenser 30 flow through pipe 39 into a purge chamber'64 and are compressed by particles of mercury spilling over from pipes 27, 40 through a pipe 61 and a small bore drop tube 65 leading to a seal 67 open to the atmosphere. Mercury returns from this seal by a pipe 57 back to the generator 1. The sludge chamber 50 is preferably located to receive heat from the hot vapour pipe 5 In a modification the wide bore pipe 44 from the bottom of the evaporator is extended downwards to provide a heavy column to compress the sludge collected in it. This causes separation of the refrigerant and the mercury coalesces and flows freely to the drain conduit 49.

IPC: C21D9/667
Filed: 1952-12-08
Abstract: 717,816. Annealing furnaces. GRUNEWALD, H., GRUNEWALD,. H., and GRUNEWALD, W. Dec. 8, 1952 (Dec. 19, 1951], No. 31067/52. Class 51 (2) An annealing furnace comprising a number of furnace bases on each of which the charge to be treated is arranged within an inner shell adapted to be covered during the heating period by a heating cover and during the cooling period by a cooling cover is characterized in that a plurality of shells are arranged in a closed path and that a definite number of successive shells is associated with a heating cover and a cooling cover which are arranged on a transporting device on which they are movable both horizontally and vertically in relation to the shells. The transporting device shown comprises a column 3 supporting cross beams 4, 24, to the ends of which heating covers 1 and cooling covers 25 are respectively attached. Each base is provided with a support 5 for both the inner shell 2 and the covers and is also provided with a ring 10 on the top of a heat insulating chest 9 the free centre space of the ring housing a motor driven ventilator fan 12 which serves to agitate the hot gases in the interior of the shell 2. The lower ends of the shells carry encircling sand trays 7 into which rims 8 of covers 1 are seated. The column 3 carries a telescopic tube 15 through which combustible gas is fed to the covers via the beam 4 and pipes 18 and it moves, by hydraulic or mechanical means, in a cylinder 19 in which a number of vertical slots 20 is arranged corresponding to the eight bases to be served. These slots are engaged by pins 22 carried by the covers 1. When the rising covers 1 approach their upper end positions the pins 22 are diverted into inclined tracks 23, 23a thereby causing the turning of the cross beams through 45 degrees. In addition to the guide slots 20, 23, 23a, the cylinder 19 is provided with electric connection means 27 which engage contact fingers 28 on the beam 24 when the latter is in its lowered position. By these means current is supplied to ventilating fans 26 in the cooling covers and, in the case of gas heated covers, also to fans for supplying combustion air. In electrically heated covers the means are utilized for supplying the necessary current. Fig. 3 shows the bases at a enclosed by heating covers whilst the bases at b are uncovered, the charges thereon cooling naturally, the bases at c covered by cooling covers, and the bases at d supplied with fresh charges ready for treatment. When the charges at a have been annealed the cross-beams 4, 24, are raised, turned and lowered such that the charges at d are now under the covers 1 whilst the charges at bare being forced cooled. When the heating process at d is completed the beams and covers are again raised, turned and lowered such that the fresh charges at c are under the covers 1 and the charges at a under the covers 25. The raising, turning and lowering process of beams and covers is repeated continuously.

Title: Method and apparatus for producing blended textile fibrous materials
IPC: D01G23/06
Filed: 1974-07-15
Abstract: 1477520 Blending, feeding and opening fibres CROMPTON & KNOWLES CORP 15 July 1974 [23 Oct 1973] 31292/74 Headings D1F and D1N In a fibre-blending operation, each batch of fibres is independently opened, uniformly distributed and formed, as by stuffer rollers, into a batt: tufts pulled, as by rotary beaters, from both or all the batts pass successively into a common duct wherein negative air pressure is maintained to entrain the tufts and effect uniform blending thereof within a common stream. In the apparatus shown in Fig. 1, two similar or identical machines 10 and 12 and a chute-fed opener 14 (receiving cleaned fibres through an air duct 70) supply tufts from batts of opened and uniformly distributed fibres into a blending duct 16 wherein all the fibres are intimately mixed prior to passage through a transport duct 18 to further processing e.g. sliver and/or lap forming. In each machine such as 10, Fig. 2, slabs 22 of a single fibre are loaded onto a feed apron 20 which carries them underneath a spring-loaded holding roll 24 to a spiked apron 26 which pulls tufts from the slabs and conveys them to a chute 42. Excess fibre removed from apron 26 by a comb roll 28 forms a reserve ball 30 in a hopper defined by spring-loaded wall 32: when mounting pressure from the ball closes a switch 38 it arrests the drive for apron 20 and roll 24 and allows apron 26 to reduce the size of the ball until switch reopens and normal advance of slabs, 22 is resumed. Fibres doffed from apron 26 by roll 40 fall into a chute 42 wherein they are compacted by the action of a spanker plate 46: an excess of accummulated fibre as detected by a photo-electric cell 50 causes interruption of feed apron etc. movement until the excess is cleared. Stuffer rolls 54 advance compacted fibre towards delivery rolls 56 and 58, the speed of which is controlled, Fig. 3 (not shown) to maintain uniform density of mat-erial therebetween, which form a batt from which tufts are removed by a rotary toothed beater 60 and entrained by air currents entering through openings 63 and passing into duct 16.

Title: Improvements in or relating to burners
IPC: F23D11/04
Filed: 1964-08-04
Abstract: 1,077,978. Gas or liquid fuel burners. SOCIETE GENERALE DE FONDERIE. Aug. 4, 1964 [Aug. 1, 1963], No. 31408/64. Heading F4T. A burner has means for varying the proportion of primary air to secondary air supply, the means being associated with means to vary the fuel supply and the total air supply so that this proportion increases when the latter two supplies decrease and vice versa. Combustion air is drawn through inlet 2 by fan 6 and passes a vaned deflector 10 as primary air and through register 18, 22 and vanes 13 as secondary air. A fuel injector 12 passes fuel through the centre of deflector 10. The register comprises a fixed disc 18 and a rotatable disc 22 both having corresponding slots 21, 23 and being biased by spring 28 to shut off air flow; the disc 22 is rotated by piston 49 acting through lever 50. A flap 3 in inlet 2 is controlled by a piston 63 acting through levers 60, 58, the lever 58 having adjustable stops 59 for engagement by lever 60. Fuel is supplied to injector 12 from pump 34 through heater 35, and valve 37 and separator 36 to heat the latter two; two return pipes 38, 40 contain valves 39 and 41, 37 respectively, the pipe 40 being connected to a chamber 44, Fig. 4, in separator 36. With the apparatus at rest flap 3, register 18, 22 and valve 37 are closed, and valves 39, 41 are open. Fan 6 and pump 34 are then actuated with the fuel returning to a reservoir via pipe 38. Valve 39 is closed causing pressure build up in injector 12 to move a piston to put pipe 33 in communication with the injector nozzle and with pipe 40; only part of the fuel reaches the nozzle and is ignited. Valve 41 is then closed and all the fuel reaches the nozzle and pressure builds up in separator chamber 44 to act on diaphragm 45 causing fluid from chamber 46 to act via pipes 48, 66 on pistons 49, 63 to open register 18, 22 and flap 3. As temperature or pressure in a boiler, for example, rises, the valve 37 opens under the control of a diaphragm 42 to pass a portion of the fuel back to the reservoir at the same time pressure in chamber 44 is lowered causing partial closure of register 18, 22 and flap 3.

Paper-insulated cable ends 1 are jointed by stripping the sheath 2 from the ends, baring the core conductors 6 and joining them so that the dimensions of the joint 7 do not exceed the corresponding dimensions of the conductors, pencilling off the dielectric 5 as at 8 and rebuilding it to the same extent as the original dielectric with unimpregnated paper tape, enclosing the rebuilt dielectric 9 in a removable chamber 10, and vacuum impregnating the fresh dielectric 9, thereafter removing the chamber and securing a sheath 4 over the joint to the cable sheaths 2. The cores 3 of a multi-core cable are spread to enable the joint therebetween to be made easily and the dielectric 5 is stripped off to give a stepped taper 8, the unimpregnated paper replacement 9 being of the same width, thickness and length of lay as that of the original dielectric. The ends of the cable and the cores may be sealed by rubber breeched pieces 15 and oiled tape poultices 16 fastened around them. The chamber 10 is preferably sealed at its ends 11 on the cable by oiled-tape poultices 12 and is provided with nipples 13, 14 for the vacuum pump and the impregnating compound respectively and a drain-cock 17. To improve the impregnation the interstices between the wires of the conductor ends 6 are filled with settling compound. After the removal of the chamber 10 the cores are pressed together and a sheath 4 stored on one cable end is slid over the joint and secured at its ends 18 to the cable sheaths 2. Preferably, the sheath 4 is of the same material as the sheaths 2, and armouring and further insulation may be applied to the cable after jointing.

Patent GB-316284-A (GB)
Abstract: 316,284. Soc. Anon. des Distilleries des Deux-SÚvres. July 28, 1928, [Convention date]. Acetic acid.-Pyroligneous acid is freed from impurities such as tars by treatment with homologues of cresol, so that the purified acid can be subsequently extracted with acetic acid solvents. The preferred solvents for the tars &c. are the homologues of cresol such as the ethyl, propyl, butyl and amyl cresols. Preferably the cresol homologues are mixed with a hydrocarbon which, in the subsequent recovery of the solvent by distillation forms an azeotropic mixture with the small quantity of dissolved acetic acid so that this acid is recovered. In an example a pyroligneous acid containing 10 per cent of acetic acid and 5 per cent of tars is treated continuously with one-fifth of its volume of butyl cresol (obtained by treating with zinc chloride a mixture of butyl alcohol and cresol). The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of any solvent, in place of the cresol homologues, as the purifying agent. This subject-matter does not appear in the Specification as accepted.
