Patent GB-800926-A (GB)
Title: Process and apparatus for treating textile material in continuous length
IPC: D06B1/00
Filed: 1956-07-26
Abstract: <PICT:0800926/IV (c)/1> <PICT:0800926/IV (c)/2> Apparatus for heat treating textile materials comprises a humidifying chamber having steam-heating coils and banks of steam injection coils 42, 43 and 44 which spray steam either directly on to the fabric 62 double passing through the chamber over rollers 63, 64 and 65, or indirectly on to removable lateral deflecting slats, Fig. 3 (not shown).  The textile material may alternately be entered through a port 69 and taken between banks 43 and 44 only in single pass fashion so that the material may absorb a smaller amount of moisture.  The amount of absorbed moisture may be further differed if slats and indirect injection are employed, and the supply of steam through line 47 may be regulated by a valve controlled by the main switch operating the material driving electric motor, the valve having time delay opening so that the motor may give intermittent advancement to the material without steam injection.  The exhaust steam is vented through intake sections 54, 55 and 56 and a duct 53.  In Fig. 1 (not shown) the material passes only once through the humidifier which is provided with two banks only of steam injection coils.  In another embodiment, Fig. 6 (not shown), the material is sprayed with water to increase its water content before being passed through a single pass humidifier.  From the humidifier the material is moved to a printing machine of known type, and then to washing and neutralizing baths. In yet a further embodiment, Fig. 7, the material passes through a creaseproofing bath 109 containing ureaformaldehyde, for example, a drier 111 and a heating chamber 112 which raises its temperature to 150 DEG  C. to cure the resin. Moisture is then restored by a double or single pass humidifier 113, the double pass circuit employing two chill rolls 123 and 129.  The roll 123 may, however, be replaced by a water atomizing chamber wherein the coils are supplied with cool air or other gas saturated with water vapour.  The steam injectors of the humidifiers may be modified to permit the units to be horizontally operated, and chemical substances such as ethylene glycol may be mixed with the steam for bleaching, fibre softening, curing, mothproofing or mildew preventing.

Patent GB-453671-A (GB)
Title: Improved means for applying closures to bottles, jars and other receptacles
IPC: B67B3/24
Filed: 1935-08-19
Abstract: 453,671. Applying discs to milk bottles in vacuo. SMITH, A. H., 6, Nylands Avenue, Kew Gardens, Surrey, MAREK, A. J., 22, Blackheath Park, London, and SCREETON, S. A., Ridglands, Blythe Road, Bromley, Kent. Aug. 19, 1935, No. 23250. Addition to 453,654. [Class 125 (ii)] , The parent Specification describes an apparatus for withdrawing air from partly filled bottles &c. of the type in which the closure is applied by atmospheric pressure when the bottle is exhausted. According to the present invention means are provided for preventing the vacuum pump from being connected to the vacuum chamber and/or a capsule from being fed thereto until a container is inserted in the machine and correctly positioned for the application of the closure. Bottles are raised on rests 16 which are operated by foot-levers, cams, &c. to the capping head, and the necks thereof make an airtight joint with a rubber ring 9 during the capping operation. The bottles may also be fed by any suitable conveyer. A sprocket 24 in the shaft 23 is operatively connected to a sprocket wheel 25 by means of a chain. Capsules are fed from a magazine 35 by a slide 29 which is operated from a cam 30 on the shaft 23. A rubber covered ring 48 engages the neck of the bottle and rubber pads 51 deaden the noise as the bottles rise to the capping head. An angle plate 52 contacts the inner rounded end 53 of a spring - loaded lever 54 which holds the slide in its rearmost position until released by a rising bottle. A chamber 66 is operatively connected to a vacuum pump (not shown) through the perforated plunger 40. A piston 71 is disposed within a bore 68 and is pressed outwardly by a spring 72. The piston presses on a V-shaped spring-urged lever 74, pivoted at 75. When the ring 48 is in its lowermost position this piston cuts off the vacuum from the pump. The driving means 105 is so arranged that motion will not be transmitted to the sprocket 25 and consequently to the shaft 23 until a bottle is raised to the position shown. The stoppering plunger is spring-controlled to allow for slight differences in the heights of the bottles. In operation the bottle is placed on the rest 16 and is raised until it contacts the ring 48 whereupon it carries with it the blocks 47 and the angle-plates 52 and 77. This movement frees the slide 29 and places the rear portion of the part 60 in communication with the vacuum pump. A lever 110a now clutches the shaft 104 to the sprocket 25 and the slide 29 moves inwardly to supply a capsule. The pump now evacuates the upper part of the bottle, and the capsuling plunger 40 descends on to the bottle mouth. The slide 29 is now returned to its initial position. As soon as the bottle moves downward the ring 48 does also and the port 60 is obturated. A rotary feed for capsules may replace the slide 29.
