Title: Process and plant for the industrial and continuous production of bodies in particular shaped bodies in a fibrous conglomerate particularly of glass fibres for thermal and other insulations
IPC: D04H1/00
Filed: 1954-02-22
Abstract: 752,464. Moulding binder-impregnated fibre. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N.V. Feb. 22, 1954 [Feb. 20, 1953], No. 5109/54. Class 87(2) A fibrous body or mat, e.g. of glass fibre impregnated with a binding material, e.g. thermoplastic or thermosetting resin. is shaped by rolling and jets of gas are forced through the mat to serve the double purpose of facilitating the setting of the binding material and removing any excess thereof. The fibrous mat 10, after being impregnated by being passed through a bath 12 of liquid binding material, is drawn between two hollow rollers 16, 17 with their circumferential surfaces contoured so that they co-operate to roll the material into the required cross-section and then between two hollow rollers 18, 19 contoured to complete the shaping. The rollers may be contoured to shape two sections side by side. There may however, be one pair of rollers only as there may be more than two pairs, all of similar construction. The second or later pairs of of rollers may run at a higher speed to exert sufficient traction on the material. The walls of the rollers are perforated, and one of a pair e.g. 16, has inside it a nozzle, e.g. 23, through which gas is directed to the inside of the wall so that it passes through the perforations to the fibrous mat in the nip. After passing through the mat the gas passes through the wall of the other roller of the pair, e.g. 17, which is also perforated, carrying with it excess binding material which it has removed from the mat. The action may be assisted by suction inside the second roller, applied through an axial tube e.g. 26. Thenozzles 23 &c. may be movable and spring- pressed to maintain their ends in contact with the insides of their rollers, to prevent gas leakage. The excess binding material emerges through the perforations of the rollers, e.g. 17 and into a trough 25 whence it may be collected. When there are two pairs of rollers, as shown, the conditions are that the gas primarily removes excess binding material between the first pair of rollers and its curing effect is only secondary. and that the gas primarily cures the binding material between the second pair of rollers and its pressure only removes the last of the excess binding material. With this object the pressure of the gas at the first pair of rollers is higher than at the second, and the temperature is conversely lower. For the required density, specific heat and chemical inertness a suitable gas is superheated and dried water vapour. The jets may be applied separately from the rollers and at the end of the process cold jets may be applied. As it issues from the last pair of rollers the moulded product is cut into lengths. e.g. by a circular saw 22. There may be heating and cooling tunnels at the entrance and exit of the machine. The product is intended' for thermal and acoustic insulation.

Abstract: 926,619. Coating with aluminium. CONTINENTAL CAN CO. Inc. Feb. 17, 1960, No. 5560/60. Class 82. The Specification relates to the coating of metal with molten aluminium and discloses two embodiments. In the first, excess aluminium is removed from the substrate by wiping with a device having a contacting surface of aluminium carbide or a silicide or boride of chromium, tungsten or titanium, and the coated metal then quickly chilled. As shown in Fig. 1, steel strip S is cleaned of surface oxides by being heated in hydrogen in chamber 11, before being passed through molten aluminium in bath 14. Excess aluminium is removed by wiping rollers 19 (which are made by dipping graphitic carbon cylinders in aluminium to produce an aluminium carbide surface), and the coated strip CS then chilled by rollers 21. In the second embodiment, the molten aluminium is applied to the substrate by a device having a contacting surface of aluminium carbide or a silicide or boride of chromium, tungsten or titanium, and the coated metal then quickly chilled. As shown in Fig. 4, steel strip S is passed between coating rolls 40, chilling rolls 46 and then chilled further in water bath 55. Rolls 41 take up molten aluminium from baths 42 and feed rolls 40 with this metal. Both rolls 40 and 41 have wettable surfaces of aluminium carbide &c.

Filed: 1947-02-27
Abstract: Each effect of a multiple - effect evaporator comprises (Fig 1) a tube bundle 14 mounted between tube sheets 22, 24 in a casing 11 which also contains a liquor/vapour separator 12 disposed above the upper tube sheet and communicating with the interior of the tubes, and also comprises an annular chamber 16, defined by casing 11, partition 36 and ring 38, which is in open communication at the top with the exterior of the tubes, and is used to remove entrained liquid from the live steam, or vapour from an adjacent effect, introduced tangentially through pipe 42. The feed effect 104 of the <PICT:0658176/III/1> <PICT:0658176/III/2> backward - flow triple - effect evaporator shown in Fig. 2 has two additional annular chambers 18 and 20 (Fig. 1).  Superheated feed liquor is supplied to chamber 18 through connection 49.  Part of the feed flashes into steam and is withdrawn through connection 50 and passed to chamber 12 through pipe 134 which may contain a check valve.  The desuperheated liquor is withdrawn through connection 48 and supplied to the interior of the tubes via connection 52.  As the liquor rises in the tubes part of it evaporates, and a mixture of liquid and vapour emerges from the tubes and strikes baffle 54 in chamber 12.  The separated liquid is removed through pipe 110 and pumped to the tube bundle of the next effect 102.  The superheat in the condensate of effect 102 is utilized in effect 104 by passing it through pipe 140 and connection 62 to chamber 20, where it flashes.  The flashed vapour passes over partition 60 into contact with tube bundle 14, and the de-super-heated liquid flows through hole 64 into section 26, where it mixes with the condensate from the tube bundle, and then passes out of the apparatus through connection 66.  Steam is supplied to the first effect 100 through pipe 136, and concentrated liquor is withdrawn from effects 100 and 102 through pipes 122 and 121 respectively.  Specification 658,239 is referred to.

Clutch-actuating mechanism with automatic wear adjustment comprises a control lever 46 pivoted at 52 to a clutch housing 44 and connected by a strut 64 to a transfer lever 48 which is pivoted at 66 to the housing and is connected by an adjustable link 80 to a lever 50 which is also pivoted at 66 and which actuates a clutch control bearing 40. Engaging springs 106b bias the levers 46, 48, 50 anti-clockwise to shift the bearing 40 to the left to engage the clutch, a control rod or cable 56 being provided for pivoting the. levers clockwise to permit conventional release spring straps to disengage the clutch. The levers 46, 48 are biased together by a spring 74 to retain the strut 64 in position. The adjustable link 80 comprises, as shown, a bolt 80b non-rotatably mounted in the lever 50 and a nut 80c rotatable in the transfer lever 48. A spring 89 wrapped around the nut forms a one-way clutch and has an end 89a co-operating with a slot in a member 88 fast with the control. lever 46. The length of the slot corresponds to the normal engaging movement of the linkage, the spring end 89a passing from one end of the slot to the other during engagement or disengagement. On the occurrence of wear the linkage travels a greater distance during clutch engagement, the end of the slot engages the end of the spring 89 and shifts it angularly about the nut 80c. When the clutch is disengaged the other end of the slot engages the spring which tightens about the nut and then rotates it and thereby decreases the length of the link 80 to compensate for wear. In a modification a nut is fast in the transfer lever and the spring is wrapped around the bolt which is rotatable in the lever 50.
