Title: Process for imparting a soft handle to textile materials
IPC: D06M15/423
Filed: 1940-06-27
Abstract: 542,173. Treating textiles with liquids; waterproofing. COURTAULDS, Ltd., and MACGREGOR, J. H. June 27, 1940, No. 10963. [Class 15 (ii)] [Also in Group VIII] A soft, full, silky handle is imparted to textile materials by treating them with a solution in acid of a water-insoluble product obtained by the interaction of cyanamide and formaldehyde under alkaline conditions and simultaneously or thereafter treating the materials with a solution of a soap or soap-like product. The soap or like product is an ionizable surfaceactive substance containing at least one alkyl radical with 8 or more carbon atoms, e.g. an alkali salt of a fatty or sulphonated fatty acid, or of a sulphonated or sulphated fatty alcohol, or of a sulphonated fatty acid amide such as oleyl methyl tauride, or of a sulphonated alkyl benzimidazole, or it may be an alkyl oxymethyl pyridinium salt, an alkyl pyridinium salt, or an alkyl quaternary ammonium compound. The materials may be treated with a solution of an electrolyte, e.g. ammonium sulphate, sodium acetate, potassium tetroxalate, or aluminium thiocyanate, followed by a drying treatment before the treatment with the soap-like product. Treatment with electrolyte may be effected at the same time as or subsequently to the cyanamide-formaldehyde treatment. The process may be combined with anti-crease, delustring, water-proofing, and other treatments. In an example, viscose warp satin fabric is padded with a solution in dilute acetic acid of a cyanamide-formaldehyde compound. It is then squeezed, passed through ammonium sulphate solution, dried, and heated at 140‹C. It is washed with dilute ammonia and then treated with a solution of soap containing a wetting agent. The treated fabric has a soft handle and is of reduced lustre. Viscose warp fabric is soaked in an acetic acid solution of cyanamide-formaldehyde, rinsed in soft water, and treated with a solution of cetyl pyridinium chloride, rinsed, and dried. Viscose fabric is treated with cyanamide-formaldehyde and then with an aqueous dispersion containing octadecyloxymethyl pyridinium chloride and sodium acetate. It is dried and then heated at 140‹C. It is washed, treated with soap solution, rinsed, and dried. The fabric is water-repellent, and of reduced lustre, and it has a soft handle. Viscose fabric is treated with cyanamide-formaldehyde and then with urea-formaldehyde. It is squeezed, dried, and heated, and then soaped, rinsed, and dried. It has a soft handle, reduced lustre, and good resistance to creasing. The process may also be applied to cellulose acetate fabrics. Specification 515,847 is referred to.

Filed: 1941-08-29
Abstract: 550,509. Converting; phase changing. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 29, 1941, No. 11031. Convention date, Aug. 31, 1940. [Class 38 (ii)] To maintain constant the current transmitted through a valve or reversely connected valves 13, 14 the peaking transformer 19 supplying the igniting voltage impulses has two primary windings arranged to give a resultant flux shifting in phase with changes in the supply volts. A winding 27 is supplied through a circuit 35, 36, 37 which is tuned to the supply frequency to eliminate harmonics and is predominantly resistive and a winding 28 is supplied through a circuit comprising also. harmonic eliminating elements 39, 40 but including a non-linear inductance 38 whereby the circuit is made predominantly inductive, i.e. a non-linear resonant circuit operated below resonance. The current in winding 28 increases with an increase in supply volts due to saturation of the inductance 38, and thereby the phase of the resultant flux due to windings 27, 28 and the phase of the ignition peaks is retarded to compensate the supply voltage change. A non-linear resistance 42 may shunt the winding 27 to distort its impressed voltage and improve the compensation. The windings may be supplied through a network permitting joint adjustment of phase by a resistor 23. A welding load 10 is shown. Specification 9759/41 as open to inspection under Sect. 91 is referred to.

Title: Improvements in or relating to trigger pulse generator circuits
IPC: G01R13/34
Filed: 1965-03-16
Abstract: 1,081,184. Delayed trigger circuits. TEKTRONIX Inc. March 16, 1965 [March 23, 1964], No. 11036/65. Heading H3T. A synchronized astable multivibrator is used to trigger a further relaxation generator, and means are provided to prevent triggering of the latter for a predetermined time after the input signal to the multivibrator, which thus executes several cycles and has time to settle down. In Fig. 1 the input signal is applied at 36 via a common-base amplifier 24 to a tunnel diode 10 which can be monostable or astable depending on its operating current controlled by switch 21. The invention, however, is confined to the astable mode. When the tunnel diode passes into its high-voltage state, the voltage pulse across inductors 12, 14 increases the conduction of a backwardly connected tunnel diode 44 and short-circuits the current supply. The current of tunnel diode 10 is then supplied by transistor 24 and is independent of the frequency or rise time of the input signal. The output of the tunnel diode is differentiated at 46, 52 and applied to a further tunnel diode 50 to trigger it to its high-voltage state; the negative pulse at the end of the input pulse is blocked by diode 48. The output of the tunnel diode 50 is differentiated by capacitor 108 to form the output signal, and is also passed to a monostable circuit 86, 101 via an inverting amplifier 61. The negative output from 61 is fed back through resistor 67 to block the first tunnel diode 10 from being triggered until the pulse from the second tunnel diode has finished; at the same time the portion of the first tunnel diode current which was supplied through resistor 64 is cut off. Capacitor 80 is normally charged through diode 84 and resistor 82 clamped by transistor 86. The negative pulse from transistor 61 causes diode 78 to conduct and allows capacitor 80 to discharge through resistor 70, 72, 74 until the ramp voltage so produced cuts off transistor 101. The collector voltage of 101 then rises and cuts off transistor 86 allowing capacitor 80 to recharge through diode 84 and resistor 82; transistor 101 then conducts again. The positive step voltage on the collector of 101 is inverted by transistor 58 to a negative pulse which turns tunnel diode 50 back to its low-voltage state, provides the trailing edge of the output pulse at 114, and (after inversion by transistor 61) cancels the blocking voltage applied through resistor 67. When this negative pulse ceases, tunnel diode 50 can again be triggered by the first tunnel diode 10. The output pulses 112, 114 can be used to trigger the timing unit in a sampling oscilloscope. Switch 116 alters the circuit constants for fast running. The tunnel diodes can be replaced by valves or transistors.

The Merz-Price current-balance protective arrangements of Specifications 667,687 and 669,595 are modified by energizing the transient bias winding on the transductor device associated with another phase. This is to prevent undesired tripping in the case, for example as occurs on some occasions when a three-phase transformer is switched in, in which the transient currents on two phases are asymmetrical, but substantially symmetrical on the third phase. In this event the transductor having the A.C. operating winding energized by the symmetrical out-of-balance component is biased by the asymmetrical component derived from another phase in the transient bias winding, and the transductor having the transient bias winding with no asymmetrical component is biased by the "self biasing" action of its A.C. operating winding which is energized by an asymmetrical out-of-balance component. In cases where this self-biasing action is insufficient two transductors may be associated with each phase, one having a transient bias winding energized from the same phase and the other having a transient bias winding energized from another phase.

Title: An improved process for preventing corrosion on metals
IPC: B05D7/16
Filed: 1934-04-17
Abstract: A process for preventing the corrosion of a metal article formed by working a metal body at an elevated temperature, consists in applying a paint to the new metal surfaces exposed by working the body, when said body has cooled down from the working temperature to a temperature between the limits 60 and 120 DEG  C. The work piece may be de-scaled prior to painting.  As an example, a rolled steel plate is subjected to the scrubbing action of a wire brush during or after its last pass through the rolls and, when the plate has cooled down to 80 DEG  C., a paint comprising white lead and boiled linseed oil is applied to all exposed surfaces. Specification 284,191 [Class 95], is referred to.

Title: Improvements in or relating to modulating arrangements for telephonic transmitters
IPC: H04B14/00
Filed: 1932-04-22
Abstract: 387,182. Wireless transmitting systems. PUNGS, L., Technische Hochschule, Brunswick, Germany. April 22, 1932, No. 11664. Convention date, May 2, 1931. [Class 40 (v).] In wireless systems of the kind in which the mean amplitude of the carrier wave is varied proportionally to the strength of modulating signal, it is found that owing to the square law response of a normal detector, the difference between loud and soft passages is accentuated. To overcome this defect, the invention provides means for varying the carrier wave amplitude in non-linear relation to the strength of the modulating signal. One manner of effecting this is by so arranging the premodulation signal amplifier that it amplifies weak signals more strongly than loud signals. A four-electrode amplifier D, Fig. 2, may be used, with the modulating voltage applied through a transformer T1 to the outer grid, and with the inner grid R biassed to a variable extent dependent on the D.C. voltage obtained by rectifying the modulating voltage by means of the transformer T2 and diode valve G1. The modulating voltage distorted in this way is then fed to the carrier-wave modulator. In an alternative method, which may be used in conjunction with that already described, the rectified signal voltage controls the carrier-wave modulator directly. Fig. 6 shows an exapmle, in which the microphone M feeds an amplifier V1 from which the signal voltage is applied through a transformer T1 to a modulating valve R1, fed with carrier current from a source H.F. The mean carrier current is determined bv the bias on the grid of the valve R1, which is dependent on the voltage across the condensers C1, C2. A rapid increase of carrier current, as the signal strength rises from zero to small amplitudes, is caused by charging the condenser C1. This. condenser is connected through choke coils to a resistance in the plate circuit of a valve R2. The grid circuit of this valve includes a battery B1 and resistance W. The output of a signal rectifier G2 includes a relay K. At small signal amplitudes, the relay K connects the grid directly to the filament, and the variation of current through the valve gives a charge to the condenser C1. As the signal strength rises further, the condenser C2 is charged.from a rectifier G1 fed by the signal input through an amplifier V2, thus giving a further steady rise of carrier current. A choke coil D ensures that the relay K responds only to variations of signal intensity, and not to the audiofrequency signal current itself. The trip device K may comprise a glow-discharge tube. More than one trip device may be used, and they can be arranged to trip at different values of signal strength, so that the non-linear relation between signal strength and carrier current assumes a stepped form.
