[Class 42 (ii)] [Also in Group VII] Hoods for felt hats or muffs are formed on a machine having at least one perforated former mounted to rotate on a horizontal axis and adapted to be successively moved from a forming position to a spraying position by means of a vertical member supporting said former, or formers, which is movable in its own plane. Diametrically opposed openings 18 are formed in a circular plate 8 rotatable with a shaft 7 which is mounted in bearings 5, 6 secured to uprights 2, 3 of a main frame having a base 1 and an upper cross-frame 4. Helical fan wheels 19, driven by motors 20 fixed to the plate, extend within the openings 18. Plates 32 having circular openings 35 are pivotally mounted on shafts 31 fixed to the front face of the plate 8 and are pressed against the latter by springs 34. Clutch rings 48, Fig. 2, which are adapted to drive double reduction gear mechanisms 52 housed in boxes 38, engage the hub ends 47 of the fans 19 to slowly rotate cylindrically- or conically-shaped formers 46 which are connected to shafts 41 by members 44. The boxes are supported by frameworks 37 in the openings 35. The fans 19 exhaust through spiral chambers 21 which each lead into a central tube 23 extending into a stationary box 26 having a perforated cylinder 27 for collecting stray fibres. Automatic electric switchgear may be operated to drive in steps a motor 15 having solenoid controlled brake mechanism 16. The motor 15 drives a pinion 11 which engages teeth 10 formed on the periphery of the disc 8 to rotate the latter in steps of one half of a revolution from a hood-forming position A, where a rotating former 46 extends into a forming tank 57 constructed in part by a member 9 fixed to the disc 8 and having windows 67, 67a, so that a predetermined amount of fibre is collected evenly on the former, to a spraying, planking and removing position B, where hot water is sprayed through a perforated box 68 on to the hood. In this position, the hood is also hardened by 'a roughened rotating cylinder 76 which is given axial and circumferential vibrating movements by a unit 82 driven by a motor 81 which, together with the cylinder 76, is mounted on arms 78 pivoted to a part 75 of the main frame. The hood is removed at the position B when the plate 32 is lowered by a handle 33 through a right angle to disengage the former 46 from the rotating mechanism and allow the hood to be cut away from the former. For each operation, an operator places sufficient fibre to form a hood on to a conveyer belt 58 where it is fed forward between rollers 63 to a second picker 64 where a brush 65 carries it with a current of air into tanks 66 and 57. The feeding rollers have a width equal to the height of a former.

Title: Raster correction
IPC: H04N3/237
Filed: 1968-04-26
Abstract: 1,223,711. Cathode-ray tube operating circuits. ZENTRALLABORATORIUM FUR RUNDFUNK - UND FERNSEHEMPFANGSTECHNIK. 26 April, 1968, No. 20064/68. Heading H4T. Distortion of the scanned raster on a cathoderay tube screen (e.g. pin cushion, barrel &c.) is corrected by controlling the operating voltage of at least one deflection waveform generator by a suitable function, parabolic, hyperbolic or exponential, of the waveform produced by the other deflection generator. Thus, as shown in Fig. 1, voltage regulating stages 6 and 7 controlling the operating voltages supplied to the line and frame sawtooth wave deflection generators 1 and 4 respectively are themselves controlled by the outputs of respective function generators 8 and 9 comprising one or more integrating elements supplied with the outputs of the frame and line generators 4 and 1 respectively. When one of the deflection waveform generators is not provided with a voltage regulating stage the raster correction due to this component of deflection may be corrected by a known transductor arrangement coupled to the other deflection waveform generator (Fig. 2, not shown).

Title: Device for separating fibres from an entraining airflow
IPC: D01G23/02
Filed: 1969-04-22
Abstract: 1,261,576. Air filter. LUWA A.G. 22 April, 1969 [2 May, 1968], No. 20565/69. Heading B1T. A filter, for removing entrained fibres from an air stream drawn from adjacent textile machinery, comprises a tubular filter element 48 into which the air flows at the top and whose lower end opens into a sack 12 for receiving the fibres, a vertically reciprocating annular plunger 26 periodically compacting the' fibres by pushing them further into the sack. In Fig. 1 the sack 12 is pervious and serves as the main air filter element, element 48 being folded in re-entrant fashion at 52, 54 and biassed by spring 62 to its retracted position. The bottom of element 48 is attached to plunger 26, and when the plunger is extended (Fig. 2, not shown) the element opens out, and its lower half extends clear of the housing 10 and temporally filters the air flowing down the element from inlet 42, 44. The pressure drop across bag 12 is monitored by means 70, which switches on a motor (38) to rotate a set of three screws 32 threaded into sleeves 33 to whose lower extensions 30 the plunger 26 is secured. The plunger then descends, until lower limit switch 66 reverses the motor, then rises until upper limit switch 66 cuts it off. A device 74 monitors the plunger movements, and gives a signal when they become too frequent because bag 12 is full. The plunger could alternatively be pneumatically/hydraulically actuated. Instead of being telescopically folded, element 48 could be of bellows construction or simply made of elastic material to follow the movements of the plunger. In Fig. 4 (not shown) the sack 12 may be impervious, the element (48') is not extensible and fan (46') is connected to the space outside and downstream of the element. Plunger 46 descends through the element to push fibres therefrom into the sack through a lower hopper (86) whose wall is toothed to prevent fibres passing upwards. A plug of fibres may seal the hopper so that there is no need to Secure the sack therearound.

Filed: 1927-08-04
Abstract: 275,637. Bemberg Akt.-Ges., J. P. Aug, 5, 1926, [Convention date]. Apparatus for making filaments.-In the production of strong threads from filaments produced by the stretch-spinning process, particularly from copper-ammoniacal solutions, two or more groups of filaments are produced separately and travel adjacent to but separated from each other through a stream of precipitated liquid by which they are treated until they have lost their stickiness, whereafter they are led from the spinning apparatus united into a single strong thread. As many funnels as groups of filaments, may be employed, the funnels all opening into one outlet tube, or instead of using funnels in an outer casing, the casing itself may be of funnel shape, the interior funnels being omitted. The apparatus shown in Fig. 1 has two spinnerets a<1>, a<2> at the top of the casing b. The single funnel c has an outlet d, the precipitating liquid being admitted by a tube c. The groups of filaments f<1>, f<2> are kept separate until they reach the outlet tube d, where they are united. A single spinneret may be used with groups of holes to form separate groups of filaments. In the form shown in Fig. 3, the funnel is divided as at c<1>, c<2>, each portion taking a group of filaments. The precipitating liquid may be admitted at c as before, or by separate pipes which may be at the tops of the funnels. In the form shown in Figs. 5 and 6, three casings b<1>, b<2>, b<3> have a common outlet d, the precipitating liquid being admitted at c<1>, c<2>, e<3>. or at c<4>.
