Title: A spinning and doubling process and devices for performing the same
IPC: D01H7/18
Filed: 1934-02-23
Abstract: 432,373. Spinning and doubling yarns. FREUND, W., 113, Weststrasse, Chemnitz, Germany. Feb. 23, 1934, No. 5936. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 2, 1934.] [Class 120 (ii)] Yarn is spun or doubled without ballooning by means of carriers arranged around the upper part of a cap or hood mounted on a driven spindle, or on the spindle itself, by which it is engaged and then passes in helical coils around the cap or the spindle to a brakmgdevice, which may be constituted by a traveller, and is wound on a spool or the like. As shown in Fig. 1, yarn passes in a path determined by carriers or pins 7 around the conical and cylindrical surface of a cap 6 and over a braking surface 11, adjustably mounted in a groove in the rim of the cap, to a tube 12 splined on a rotary spindle. Various forms of caps are described arranged, as shown in Fig. 4, on the tips of the spindles, the yarn being guided by carriers o and passing in a helical path around the tube b, is led to the tube by a traveller h. The caps may be dished or shaped to facilitate guidance of the yarn, and may be formed in two parts so that the upper part which is subject to wear may be formed of hard metal and be easily renewed. As shown in Fig. 13, channels and ducts 102-107 may be provided so that air drawn in by the radial ducts 104, 105, 106 causes the yarn to cling around the cap, and the air issuing from the ducts 107, while not affecting this action, serves to blow away loose fibres. These channels may be formed in the spindle.

Title: An instrument for measuring the consistency of a liquid
IPC: G01N11/00
Filed: 1952-03-07
Abstract: 701,727. Electric indicating systems. STENSON, A. V. W. March 7, 1952, No. 5941/52. Class 40 (1). The consistency of a liquid e.g. density, viscosity, &c., is measured by allowing the liquid to react on a high frequency electromagnetic field derived from a crystal stabilized oscillator. For a particular size of the sampling drum and consistency of the liquid therein, the liquid molecules will resonate, producing a maximum intensity or energy level of the oscillator output. Alterations in consistency alter this energy level; the deviations in energy level are detected and used to move a metallic plate relative to the drum to restore the energy level to a maximum, the movement of the plate then being a function of the liquid consistency. The balancing may be effected manually or automatically and temperature compensation provided. As shown, the liquid under test is contained in or flows through a sampling drum 1 of insulating material having a metal back 3. A H.F. loop-coupler 12 energised from a wave generator is disposed near the front face of the drum and crystal controlled to produce resonance for a predetermined liquid consistency. Deviations from maximum energy level arising from alterations in the liquid consistency are detected in known manner at 13 and cause a servomotor 9 to run in a sense corresponding to the sense of the deviation to unbalance a differential bridge circuit 7, which drives a servomotor 6, to move a metal plate 5 axially through a screw and nut mechanism to the balance position i.e. where the energy level is again at a maximum. The movement of the servomotor 9 which is proportional to liquid consistency may actuate a pointer or a recorder 11. Variations in temperature of the liquid are . sensed by a detector bulb 10 and function tl rough a servomotor 8, the bridge 7 and motor 6 to adjust the plate 5 to restore balance without affecting the recorder 1. In another arrangement the bridge circuit 7 and motor 6 may be dispensed with, the two servomotors 8, 9 actuating the plate 5 through a mechanical microscrew differential. The plate 5 may be disposed behind the drum 1. Alternatively both inputs to the microscrew differential may be set by hand according to instruments reading the liquid temperature and resonance deviation. The temperature control may be dispensed with if the temperature of the liquid is regulated.

Title: An improved apparatus for regulating voltages
IPC: G05F1/32
Filed: 1963-02-14
Abstract: 1,021,295. Automatic voltage regulation. COMPAGNIE GENERALE DE TRAVAUX D'ECLAIRAGE ET DE FORCE ANCIENS ETABLISSEMENTS CLEMANCON. Feb. 14, 1963 [Feb. 15, 1962], No. 6050/63. Heading G3X. An output voltage at terminals 8 is derived from a source 1 over a magnetic amplifier 4 having control windings a and b, an auto-transformer 6 and a filtering element 7, and is stabilized by the action of the control windings a and b which are connected in series so that their magnetic fields are in opposition and which are supplied from the source 1 over a transformer 2 and a rectifier 3. The voltage across winding a is stabilized by a Zener diode 5, so that any variation in the supply voltage affects the winding b only. The magnetic amplifier 4 is so designed that variations in the supply voltage which would normally affect its output are counteracted by the corresponding variations in the combined effect of the windings a and b, whereby the output voltage at terminals 8 is maintained constant.

Title: Process for improving patterned fabrics
IPC: D06P5/00
Filed: 1953-03-06
Abstract: Fabrics composed of natural cellulose, regenerated cellulose or cellulose derivative fibres, which have a transparent or translucent foundation and an opaque pattern capable of shrinking under the action of shrinking agents to a greater extent than the base, are subjected to a shrinking treatment and are then tensioned whilst drying and ironed or pressed.  The patterned fabric may be obtained by printing with a reserve such as rubber, gum arabic, solutions of cellulose esters or ethers insoluble in water, varnishes, modified or unmodified or substituted synthetic resins or synthetic resin precondensates, and then treating the fabric with a transparentizing agent, selected from aqueous solutions of potassium or sodium hydroxide, aldehydes, sulphuric, nitric or hydrochloric acid, ammonium or calcium thiocyanate, carbon disulphide, cuprammonium solution, mixed nitric and hydrochloric acids, zinc chloride, dimethyl dibenzyl ammonium hydroxide, tetramethyl ammonium hydroxide, a mixture of acetone or chloroform with ethyl alcohol, or acetic or formic acid.  The agent and its concentration and temperature are selected according to the materials treated.  The transparentizing solution may include buffer salts, e.g. Glauber salt, ammonium sulphate or common salt, and also ethyl alcohol, glycerine or pyridine.  After transparentizing, the fabric may be washed and is then treated with a shrinking agent, which agent and its temperature and concentration are also selected according to the fibres treated. Suitable shrinking agents are aqueous solutions of sodium and/or potassium hydroxide, cuprammonium solution, calcium or ammonium thiocyanate, zinc chloride, dimethyl dibenzyl ammonium hydroxide, tetramethyl ammonium hydroxide, hydrochloric acid, nitric acid, formaldehyde, mixtures of alcohols and aldehydes or mixtures thereof with calcium or ammonium thiocyanate or with hydrochloric or nitric acid.  Buffer salts, e.g., sodium carbonate, common salt, Glauber salt or ammonium chloride, may be included in the shrinking solution. Mixed fabrics may be used, and one type of fibre may be shrunk independently of the other or both types may be shrunk simultaneously.  Prior to the patterning treatment the fabric may be bleached, desized, mercerized or digested.  After shrinking, the fabric may be neutralized and washed, and is dried on a tenter to an extent to produce a smooth fabric or beyond this extent to its original dimensions or beyond.  Following this, the fabric may be ironed or pressed in hot calenders.  The shrinkage treatment is carried out without tension.  The examples refer to the treatment of cotton muslin, regenerated cellulose and cellulose acetate fabrics.

In a mixing apparatus the ratio of water to particulate material is maintained constant, despite variations in the initial water content of the material, by controlling the supply of both water and particulate material in accordance with variations in the specific weight of the latter. In the drawing accompanying Provisional Specification the weight of sand on belt 3 is sensed by hydraulic device 18 which controls the setting of a potentiometer 20. The potentiometer controls an actuator 24 coupled to a potentiometer 22 which varies the speed of a variable speed, constant torque motor 4 by way of a control unit. The initial speed of motor 4, and hence of belt 3 is controlled by potentiometer 30. Potentiometer 20 also controls actuators 14, 15 to vary the setting of a water supply valve 9 by way of motor 13, the initial setting being determined by potentiometer 29. The rate of supply of sand may be controlled by means of motor 31, adjusting gate 2, instead of by motor 4. In a modification a potentiometer is set by way of a mechanical linkage in accordance with the specific weight of the sand and the potentiometer output is supplied to an actuator which controls a further potentiometer. The latter is connected in control circuits for the belt drive motor and the water supply control motor.
