Title: Processes for improving the properties of artificial threads and films consisting ofregenerated cellulose
IPC: D06M11/38
Filed: 1929-06-17
Abstract: 335,176. Marshall, W. June 17, 1929. Yarns &c., treating with liquids.-The softness, extensibility, elasticity, tensile strength, and even dyeing properties of regenerated cellulose threads and films and textile materials coated or impregnated with regenerated cellulose, are improved by treating the material with caustic soda of not less than 28‹ Twaddell and then removing the whole or greater part of the alkali by washing with aqueous solutions of sodium or potassium chloride, sulphate, nitrate, chlorate, or sodium thiosulphate, ammonium chloride or sulphate, or cane sugar, glycerine, or glucose. Caustic potash may be used instead of caustic soda. Preferably the strength of the caustic soda is from 40‹-60‹ Tw. and the material is treated at a temperature of 0‹-60‹ C. The alkali is preferably washed out with a solution of sodium chloride at 50‹ C. In examples, viscose yarn is treated with strong caustic soda solution and the alkali is removed by washing with sodium chloride solution; freshly spun viscose silk prior to the first drying is treated with strong caustic soda at room temperature and the alkali is washed out with warm sodium chloride, followed by treatment with dilute sulphuric acid and further washing with water.

Title: Improvements in or relating to thermionic valve amplifying circuit arrangements
IPC: H03F3/32
Filed: 1936-07-04
Abstract: 482,740. Valve amplifying circuits. BLUMLEIN, A. D. July 4, 1936, No. 18597. [Class 40 (v)] In a push-pull amplifier a negative feed back is provided so as to reduce the amplification of potentials applied to the grids in phase more than the amplification of potentials applied in push-pull. Fig. 1 shows an arrangement in which cathode resistances 5, 9 are used, and may be connected in series with small inductances to compensate for stray capacity. Alternatively the cathode impedances may be of any type and give discrimination with frequency, large low frequency interference xnay be prevented by using a high inductance choke in series with the cathode resistance. Grid bias may be taken from a tapping on the cathode resistance and direct coupling may be employed which may be of the kind described in Specification 456,450 in which the coupling condensers are shunted by resistances so proportioned relatively to the grid leak and decoupling resistance and condenser that equal gain is obtained at all frequencies. Further attenuation of " in phase " potentials may be produced by further stages or by the use of a phase reversing valve feeding in parallel with one of the push-pull valves and fed from the anode circuit of the other push-pull valve, Fig. 2 (not shown). Fig. 3 shows a circuit for the supply of scanning potentials to a cathode-ray tube in which the potentiometers 24, 25 connected across the supply to the cathode-ray tube also constitute the anode loads of the valves 22, 23. Triode valves may be used and may be neutralized by condensers cross connecting the grids and anodes, Fig. 4 (not shown) in which case the negative feed back assists to maintain stability and tends to keep the valves in balance and so improves the neutralizing balance. The output from the second pair of valves may be taken from the cathode circuit, Fig. 5 (not shown) in which case a common resistance is employed in the anode circuits to give the feed back for reducing amplification of voltages applied in phase to the push-pull pair. A substantially push-pull output may be obtained from a single input potential by earthing terminal 2, Fig. 1, and applying the signal between earth and terminal 1. Fig. 6 shows an unbalanced input and a coupling of the kind described in Specification 456,450. This arrangement may be used as a limiting amplifier for wave-shaping if the grids are driven beyond cut-off and may be so designed that grid current does not flow. The discrimination in favour of push-pull potentials is, however, only obtained while both valves are conductive. Specifications 325,833, [Class 40 (v)], 425,696, 443,589, and 448,421 also are referred to.

Abstract: 715,331. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 20, 1952 [Aug. 7, 1951], No. 18624/51. Class 40 (3). [Also in Group XL(c)] In a television receiver automatic gain control (A.G.C.) is obtained by clamping the black level at a pre-determined value and deriving an A.G.C. potential dependent upon the amplitude of the synchronizing pulses in the clamped signal. The composite demodulated signal is applied over an amplifier to the grid E of the picture-tube, via a blocking condenser C1. The black level is stabilized at earth potential by means of diodes D1, 2, which are biased to be non-conductive save during the " back-porch " period, the gating means comprising negative-going pulses derived from a winding L1 on the line output transformer. The gating pulses are suitably delayed by means of a time-delay network comprising inductance L2, condensers C2, 3 and terminating resistances R5, 6. The A.G.C. potential is derived in accordance with the synch. signal amplitude by means of a peak-rectifying diode D3, part only of the D.C. output being utilized by means of a potentiometer R7, 8. In an alternative embodiment, Fig. 2 (not shown) in which the picture tube is cathode modulated, the black level is stabilized at the grid of the video amplifier and the A.G.C. potential derived at this point.

Abstract: 102,978. Megevet, C. J., and Picker, L. Oct. 11, 1915, [Convention date]. Liquid level, maintaining.-In a lubricating system for internal-combustion engines, comprising conduits F on the connecting-rod ends which scoop oil from troughs G supplied by a pump H, the oil in the lower part of the crank chamber is maintained at a regulated level by a bird-fountain device consisting of a tank N and a pipe P, which are adjusted in height bodily by a screw O. When the oil falls below the level of the end of the pipe P, air enters the tank N, and a corresponding quantity of oil descends. A spring-pressed valve R is normally held open by a rod Q on the cover N<1> of the tank, but closes when the cover is removed, thus cutting off the supply. The level of oil in the individual troughs G is regulated by hand-operated sluices L controlling overflow openings in the sides of the trough.

Abstract: 279,546. Rayner, G. F., (Harding Engineering Co.). July 27, 1926. Surface areas, computing.-A leather &c. areameasuring machine of the Sawyer type is provided with electrical means for automatically stamping the measurement on the hide and allowing the machine to reset. Arranged in rear of the usual supporting roll 14 and contact rolls 20 are two series of rollers each comprising an upper spring-depressed roll 116, 125 extending across the machine and a number of lower rolls 115, 123, of narrow width, disposed between the conveyer belts 84. As a hide enters between the first series the separation caused thereby breaks a circuit to a solenoid 111 and allows a spring 112 to rock a lever 108 to the position shown. When the hide has passed, however, and the upper roller 116 descends to close the circuit to the solenoid the lever is rocked clockwise and raises a spring plunger 95 to force the hide against the type wheel 78 rotated in synchronism with the area indicator 51. When the hide has completely cleared the contact rolls 20, points 23 mounted at the ends of the contact roll frames 18 descend into engagement with springs 131 on a bar 130 in circuit with another solenoid 128. The circuit cannot be completed, however, until the hide emerges from the rolls 125, 123 whereupon the solenoid armature 129 is moved to the right to free the detents 58 from the measuring wheels 28 and allow them to reset. The detents may also be removed manually by means of a handle 63.

In a continuous casting method the melt is discharged into a drum rotatable about a vertical axis, and transferred to a mould by a tube by pressure due to the mass of the revolving melt. Molten metal from a ladle 14 is fed via pipe 9 into the rotating drum 6, centrifugal force driving through the metal through the tube 10 into the water-jacketed mould 21. The mould, ladle and drum are individually mounted for horizontal adjustment and the drum is also mounted for vertical adjustment on jacks 2. As the amount of metal in the drum increases the exit aperture 19 of the pipe 9 dips into it and a throttling effect occurs so that a position of equilibrium is reached when the amount of metal removed from the ladle equals that flowing into the mould. The casting 30 may be taken direct to a rolling mill.

Synchronization of the engagement of ratioestablishing positive clutches in a changespeed gear is effected by a split-spring ring having on one side a frusto-conical friction surface and a cylindrical friction surface for engagement by similarly shaped surfaces on a ratio-selecting, axially slidable striker hub, and having on its other side a set of teeth coacting with corresponding teeth upon an associated gear-wheel, the split-spring ring baulking engagement of the positive clutch teeth until synchronization has been achieved. In one form, a split-spring ring 5 has external frustoconical and cylindrical friction surfaces 6, 16. engageable by correspondingly shaped surfaces 7, 15 upon a selector sleeve 4 axially slidable upon a splined hub 3 fast with a shaft 1. The split synchronizing ring 5 has internal tapered teeth 9, 9a, 9b coacting with similarly shaped teeth 10 on the hub of a gear-wheel 2 rotatable upon the shaft 1. On initiating axial sliding movement of the selector sleeve 4 to engage splines 13 thereon with clutch dogs 14 upon the gear-wheel 2, the frusto-conical friction surfaces 6, 7 engage so that the split-ring 5 tends to turn relatively to the gear-wheel, the reaction of the teeth 9, 10 on the split-ring and the gear-wheel hub expanding the split-ring and baulking clutch engagement. On synchronization, the baulking effect ceases, and the selector sleeve 4 can then be slidden axially so that the cylindrical friction, surfaces 15, 16 slide over one another, allowing the splines 13 to engage the clutch dogs 14. In a modification, Figs. 3, 4 (not shown), the split-spring ring 5 is formed with frusto-conical and cylindrical friction surfaces on its inner periphery and teeth on its outer periphery.
