Title: Process and apparatus for the manufacture of crimped bulky filaments
IPC: D02G1/12
Filed: 1969-08-06
Abstract: 1,273,797. Crimping fibres. TEIJIN Ltd. 6 Aug., 1969 [6 Aug., 1968], No. 39375/69. Heading D1F. In a crimping operation thermoplastic synthetic continuous filaments are projected by a heated jet stream to impinge upon a moving perforated screen, which supports the filaments and permits passage of the stream therethrough, and the crimped filaments, cooled according to the movement of the screen, are subsequently removed. The screen comprises at least two layers e.g. as formed by crossing wires 1, 1' and 2, 2', (which may be of similar or different mesh or perforation size and completely separate or in contact) and each plane perforate area of the lower screen overlapping a perforation of the upper screen is smaller than the plane area of each perforation of the upper screen, Figs. 2A-F and Figs. 3A-B (not shown). The resistance to the stream offered by the lower screen is greater than that of the upper screen with the result that filaments between the screen layers are subjected (at each perforation of the upper screen) to the crimping action of a miniature stufferbox and without the disruption of reflected, turbulent eddy streams. As shown in Fig. 4A, filaments f are fed at constant rate by feed rollers 3, 4, and a guide 5 to jet 6 and are projected thereby to impinge, in plasticised condition, onto a rotating screen disc. The jet stream passes through the disc and perforations in a dished plate support therefor. The cooled, crimped filaments are removed through a guide 5'. In another embodiment, Fig. 4B, the disc is replaced by an endless screen running around drive and guide rollers 8, 8', the former of which may be grooved in the region of impingement of the jet stream to provide an escape path therefor; alternatively the roller may comprise two outer dies, over which the screen passes, separated by supporting arms between which the stream may escape, Figs. 5-B, 5B' (not shown).

Abstract: 1,155,638. Jet propulsion nozzlesvariable area. SOCIETE NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Sept.6, 1967 [Sept.7, 1966], No.40761/67. Heading F1J. The invention relates to a variable area nozzle such as a jet propulsion nozzle, the nozzle comprising a circular assembly of flaps, the flaps 1 being driving flaps and the alternate flaps 16 being follower flaps, means being provided to seal gaps between adjacent flaps to prevent leakage therethrough. The flaps are formed with pivots 1e and 16e, the pivots being disposed to form a polygon. Each driving flap 1 comprises the pivot le, a pair of radially disposed webs 1f, a transverse web 1a and an inner flange 1d which constitutes the flap surface - in Fig. 1 only one half of the driving flap is seen to the right of the line 20-20. The pivot le is formed with a through-bore, and the parts 1h of the transverse web 1a outwardly of the radiallydisposed webs 1f are formed with grooves 1g, see Fig. 2. Each follower flap 16 is similarly formed with the pivot 16e, a pair of radially disposed webs 16f, a transverse web 16a and an inner flange 16d which constitutes the flap surface. The pivots 16e are formed with recesses 23 at each end, and the parts 16h of the transverse web 16a outwardly of the radially-disposed webs 16f are formed with grooves 16g, see Fig.2. A sealing member 18 comprising a sealing surface 18b and a pivot 18a is mounted in the groove 16g of a follower flap 16, the end 18e of the pivot 18a engaging in a recess 23 of the pivot 16e of the follower flap. The sealing member 18 is secured to the follower flap by means of a rivet 18d passed through aligned holes 16m and 18c in the flap and sealing member. The adjacent driving flap 1 is assembled so that the pivot 18a of the sealing member enters the through-bore in the pivot 1e of the flap, and the exposed part of the sealing surface 18b enters the groove 1g of the transverse web la. The arrangement is such that as the flaps move from the maximum nozzle area position shown at the right of Fig. 1 to the minimum nozzle area position shown at the left of Fig.1 the sealing surface 18b and the pivot 18a move further into the groove 1g and bore in the pivot le of the driving flap 1. The pivot le of the driving flap is received within a recess 26 of an actuating member 29 which is mounted in a partcylindrical recess 32 of a fixed member 27, there being means for causing the part-rotational movement of the member 29 whereby the position of the flaps 1 may be adjusted. The follower flaps are similarly mounted but they are not driven, the follower flaps being moved inwardly by the inward movement of the adjacent driving flaps 1 and outwardly by the pressure of the gases within the nozzle. The surface of contact between the driving and follower flaps is indicated at 28. A trapezium section sealing member 35 Fig. 6 (not shown) is located between adjacent fixed members 27, 31 and associated actuating members 29, 3.

Title: Improvements relating to processes for obtaining pure methanol from crude synthetic methanol
IPC: B01D3/00
Filed: 1961-11-15
Abstract: Pure methanol is produced from syntheticallyproduced crude methanol by a process of distillation in which the crude methanol freed from dimethylether and gases is separated from easily voltatile constituents in a first column, the mixture of methanol and easily volatile constituents which accumulates in vapour form at the head of the column being compressed by a heat pump and used for heating the evaporator of this column, a part being condensed and returned as reflux to the column; the uncondensed fraction is passed to a second column where the easily volatile constituents are further enriched and removed from the process, and the liquid which accumulates in the sump is returned as reflux to the first column; the sump product of the first column is passed for the most part into a third column and freed from difficulty volatile constituents, the vapour from this column being compressed in a heat pump and completely condensed for heating the evaporator in the sump of this column, and partly withdrawn as product and partly returned as reflux to the column, the boiling point owing to the high methanol content in the sump of this column being so low that the boiling point of the sump product is lower than the condensation point of the compressed vapours; and this sump product is freed from methanol in a fourth steam-heated column, the vapours rich in methanol so produced being returned to the sump of the first column while at the same time a part of the sump product of the first column is used as reflux in the fourth column.
