Title: Gas compressors
IPC: F04D27/02
Filed: 1972-06-14
Abstract: 1343246 Centrifugal compressors; turbines INGERSOLL-RAND CO 14 June 1972 [2 July 1971] 27812/72 Headings F1C F1G and FIT A gas compressor has at least a first compressing stage 16 with at least three separate inlets in parallel for admission of gas to the stage in a common direction, at least two of the inlets being at least partially confined within another of the inlets. The first stage 16 comprises an inlet housing 36 having a port 38 through which ambient air flows to a compressor rotor 40 before passing through passageway 42 to intercooler 22, demisters 26, 26' and second compressing stage 18. The latter has a rotor 48 which, together with rotor 40, is driven by a motor (32) Fig. 1 (not shown) via shaft 58 and gearing 56. The air leaving rotor 48 flows through discharge passage-way 50 to a consumer 52, the discharge pressure being detected by sensor 86 which controls valve 80 to recycle some of the discharge air back to first stage 16 should consumer demand fall. Respective outlets of valve 80 are connected to passageways 74, 76 each of which communicates through a pair of hollow struts 64 with one or other of the chambers defined by partition 66 disposed within a hollow centre body 62 mounted in housing 36. The respective chambers define two further inlets to rotor 40 via nozzle ring 92, turbine rotor 60 and flow straightening vanes 96. Thus according to the position of plunger 82 of valve 80 discharge air may be recycled back to compressor rotor 40 through one or both of passageways 74, 76 and then turbine 60, the latter assisting drive of compressor 40 to prevent surge. The temperature of the recycled air is maintained sufficiently high to prevent icing of first stage 16, the temperature control being effected by a sensor 116 which acts on valve 114 to vary cooling water flow through inter-cooler 22 and thus maintain the air temperature leaving the inter-cooler constant. The first and second stage compressor housings 36, 46 respectively are mounted side by side in a common casing 30 from which they can each be slidably removed. The respective rotor assemblies can then also be removed.

Title: Improvements in or relating to parachutes
IPC: B64D17/00
Filed: 1921-10-21
Abstract: 192,136. V. M. L. Experimental, Ltd., and Lucas, O. D. Oct. 21, 1921. Parachutes.-The chief stresses in a parachute for smoke signals or flares are taken by reinforcing cords which pass across the fabric and are secured to the edges by gripping-eyelets. The parachute may be made of paper in one or more layers. Fig. 2 shows a plan of a parachute in which a continuous cord or series of cords B is looped through a second series of cords B<1> which are looped together in opposite pairs at the centre. The cords B are gripped to the edge of the parachute by eyelets C with interposed washers c, Fig. 4, and are extended to support eyelets E through which the suspension cords D, Fig. 1, are threaded. The eyelets C allow a certain amount of slip in the event of excessive shock. The cords D are also threaded through eyelets G secured to the main suspension' cords or tapes F, which may be of silk braid. The cords B, B' are held in place by rings of fabric J, J<1>, J' cemented to the upper surface of the parachute, the outer ring J being duplicated on the under surface. The rings may be of tough paper or thin fabric secured bv rubber solution or aircraft dope. When the parachute is made in two layers, the cords are secured between the lavers. In a modification, a cord, in one piece or several lengths, may extend from an eyelet on the edge to a large eyelet or small drum at the central hole of the parachute, passing around this eyelet and back again to a second edge eyelet and so on in succession until the whole parachute has radiating cords. A paper parachute may have the whole surface sprayed or brushed with rubber solution or dope to make it waterproof; and to assist the opening it is covered with French chalk, aluminium powder or soapy substances. According to the Provisional Specification, the reinforcing cords may be passed around or through eyelets at the edge of the parachute, the cord from each eyelet extending right across to a diametrically opposite eyelet. The ends of the cord may be loose and of sufficient length to form the loadsuspending cords. Where two sets of cords are looped together, one set may pass around a series of eyelets through which the other set is passed.

Title: Improvements in manufacture of carbon black
IPC: C09C1/50
Filed: 1952-11-17
Abstract: <PICT:0723190/III/1> An auxiliary hydrocarbon make in gaseous form is rapidly and uniformly mixed with a turbulent suspension of carbon black whilst the latter is passing through a zone of a reaction chamber downstream from a carbon-forming zone and while the suspension is still at a temperature in excess of that at which the auxiliary hydrocarbon make is decomposed, in a process in which a hydrocarbon to be decomposed is mixed with a turbulent stream of hot gases flowing through an elongated reaction chamber at a temperature in excess of that at which the hydrocarbons are decomposed to carbon black and the hydrocarbons are decomposed in a zone of carbon black formation by heat absorbed from the hot gases to form carbon black in suspension therein and a suspension of the carbon thus formed in the hot gases is continued through the chamber at high turbulence, is finally cooled and the carbon black separated therefrom, e.g. of the type disclosed in Specification 669,968.  The molecular weight and aromatic content of said auxiliary hydrocarbon should be at least as low as and preferably lower than that of the main make hydrocarbon, and the proportion of the former should not exceed 25 per cent by weight of the main make hydrocarbons, proportions as low as or lower than 1 per cent being effective.  Whilst the turbulent stream of hot gases may be longitudinally directed as disclosed in Specification 654,864, preferably in a rectangular furnace, the apparatus described in detail is of the type described in Specification 669,968, having blast burners constructed as shown in Fig. 2 wherein the hydrocarbon fuel is supplied by valve tubes 10 terminating short of the inner wall of the furnace chamber. Air is forced through the conduit 11, passes tangentially into duct 12 and thence through burner ports 8, preferably cut at an angle to utilize the whirling motion of the air in the duct.  It is preferred that the blast flame gases should be of an oxidizing character.  Examples are given in which the main makes were (1) a petroleum distillate (2) highly aromatic distillate oil and (3) a mixture of 75 per cent pressure tar i.e. heavy tar residue resulting from pressure distillation of petroleum, and 25 per cent aromatic distillate, the auxiliary make being in each case natural gas.  Similar results could be obtained with undiluted pressure tar, the auxiliary make then being natural gas or a distillate oil of lower aromatic content.  Details are given of the colour and oil absorption value of the carbon black produced, and of the properties of standard tyre tread compounds containing the carbon black.
