Extrusion machines; moulding indiarubber tubes. - Tubular articles are made from rubber latex or other water dispersion of rubber, balata, gutta percha, or the like by streaming it into a coagulant such as acetic acid so as to coagulate the latex from the outside inwardly and then removingthe core of uncoagulated latex. The latex is contained in a tank 1, Fig. 1, adjustable vertically to vary the hydraulic head, and containing stirrers 8, and is delivered by an adjustable nozzle 5 into a bath of coagulant. the length of latex being carried along by the hydraulic head, or by means of an endless conveyer band 9 of which a number are contained in the bath side by side so that a number of lengths of latex may be arranged to lie in the bath simultaneously to pickle. After the desired immersion the lengths are conducted by conveyer bands 13, 14 to a washing bath 12, where they are kept submerged by a belt 15, or, if they do not float in the washing liquid, are conducted through the liquid in some other way. They are then conducted to a mould shown in Fig. 4 which supports the tube externally while the latex is washed out by pressure air or water. The moulds, when filled, are moved to one side by a belt 20. A coagulating bath consisting of 100 parts by volume of 85 per cent acetic acid and 50 parts of 95 per cent denatured alcohol is such as to cause tha freshly coagulated latex to float almost submerged.

Title: Improvements in methods and apparatus for controlling the humidity of air
IPC: F24F3/14
Filed: 1931-06-25
Abstract: 378,153. Moistening air; preventing condensation on windows. GILL, H. A., 51, Chancery Lane, London.-(Sturtevant Co., B. F. ; Dana Avenue, Hyde Park, Boston, U.S.A.) June 25, 1931, No. 18388. [Class 55 (ii).] In humidifying systems controlling the humidity of air within an enclosure, the condensation of moisture on a window-pane or observation surface exposed in part to a lower temperature than that of the enclosure is prevented by decreasing the supply of moisture when the window temperature drops nearly to the dew point of the moistened air. The arrangement according to Fig. 1 comprises two pairs of electric circuits each pair being influenced by thermocouples outside and inside the room and including a galvanometer. The first pair comprises an outside thermocouple 10 linked with a moving coil 11 carrying a pointer and an inside thermocouple 12 linked with a moving coil 14 carrying a resistance contacting with the pointer. A circuit comprising a battery 19 and the pointer and resistance energizes a relay 17 to open a circuit which includes an alternating current source 84 and a motor 18 adapted to close a valve 20 in the humidifier supply pipe. Coils 11, 14 are oppositely wound so that an increase of current in both circuits causes both to recede from one another and thus has a double effect in diminishing the resistance 16 in the relay circuit. The second pair of circuits comprises an outside thermocouple 23 and an inside wet bulb thermocouple 26 co-operating respectively with differential field coils 24, 30 of a galvanometer 25 whose pointer 32 is adapted to make or break a relay circuit controlling the motor circuit of a valve 36 in the humidifier supply pipe. The control circuits are arranged to operate at the dry and wet bulb temperatures corresponding to given values of outside temperatures according to a graph obtained from working tests so as to maintain the greatest relative humidity without condensation appearing on the window. In one modification both relays influence a single valve motor circuit. In another the humidifier is shut off when dry and wet bulb temperatures of air adjacent to the window are equal, the thermocouple circuits including either a galvanometer as before or a relay, the currents generated opposing one another so that when they are equal the relay is de-energized and the valve motor is set in motion to shut off the humidifier. A finned metal surface may be mounted in a portion of the window to cool the air passing the wet bulb thermocouple, the inside fins providing an elongated path for a sample of air drawn in by a fan.

Abstract: 726,944. Double-twist spindle. MORAWEK, W. July 22, 1952 [July 28, 1951; May 31, 1952], No. 18554/52. Class 120 (2). A textile double-twist spindle having a rotating stem and a rotating cap for guiding the thread after passing through the thread outlet opening in the stem is characterised in that the rotating cap at its lower part has a radially tapering peripheral gripping groove adapted to grip the thread by a wedging action thereon. In the arrangement shown the cap 6 has secured to it a notched disc 7 so as to form a tapering groove there-between. Thread leaving the stem 13 through the opening 10 is wrapped round the grooved boss 11  to the desired extent and introduced into one of the notches 8<SP>1</SP> to 8<SP>6</SP>. On rotation of the spindle the thread tends to accumulate in the gripping groove 8, the degree of accumulation depending on the running-off conditions, before forming the normal thread balloon. In another embodiment the bottom of the cap is provided with a detachable ring with an opposing ring pressed resiliently there-against. The gripping groove 8 may extend around the entire circumference of the cap or may be broken up into a number of sectors or reduced to a single sector. In further embodiments the rings or discs forming the groove 8 are provided with bulges or corrugations which may be arranged either so that their highest points are in contact or so that the bulges of one part engage in the gap between bulges of the other part, thus giving a discontinuous gripping effect.

Title: An improved process and apparatus for making artificial silk effect yarn, by production of knots, snarls, or the like
IPC: D01D5/20
Filed: 1936-07-06
Abstract: Artificial silk effect yarn having knots, snarls or the like along its length is produced by causing a group of elementary filaments to issue from a spinning funnel with large exit velocity, fall upon an impact plate, and be withdrawn therefrom at a lower velocity.  The hastening forward of the thread and the formation of snarls, or balls, on the impact plate is promoted by diminution of the rate of coagulation, e.g. by lowering the temperature of the precipitating water.  The high velocity of the filaments issuing from the funnel may be effected by increasing the quantity and exit velocity of the precipitating water.  The <PICT:0460626/IV/1> <PICT:0460626/IV/2> impact plate may be tilted backwards, or it may be made concave in order to facilitate the formation of the knots or swellings.  As shown in Fig. 1, a group of elementary filaments 2 issues from the spinning funnel 1 and falls with the precipitating water on to the inclined plate 3 to form a small thread heap 8 as a result of the hastening forwards of the thread and the incomplete coagulation. The thread is withdrawn from the heap with constant withdrawal velocity and from time to time, the little heap is carried along as a whole with the thread.  The thread passes over guide 4, and acidifying channel 5 to reel 6.  As shown in Fig. 3, the impact plate is in the form of a concave dish.  In both constructions the inclination of the impact plate may be adjusted.  In an example, cuprammonium cellulose solution is spun into a spinning funnel with an exit opening of 6 mm. diameter.  The precipitating water flows at the rate of 1 litre per minute and the temperature is maintained at 30 DEG  C.  The thread is withdrawn from the impact plate at the rate of 60 metres per minute. The thread has knots or swellings at intervals along its length, and has a titre of 200 deniers.  In another example, the quantity of water is not greater than normal, but the exit velocity in increased by using a funnel having an exit orifice of only 0,3 mm.
