Abstract: 561,160. Valve generating circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and CAMPBELL, C. F. Nov. 4, 1942, No. 15527. [Class 40 (v)] Stability of frequency in an oscillator of the electron - coupled type and using an iron-cored inductance is obtained by arranging a non- linear impedance in the circuit so as to control the oscillatory current flowing in the inductance with varying operating voltages. The Figure shows a screen-grid oscillator with the screen grid connected to a potentiometer arranged in series with a non- linear resistance NLR of the silicon carbide type or a non-linear element comprising an iron-cored choke or a glow lamp of the metallic filament type. In this way an increase in the supply voltage will decrease the 'impedance NLR and thus the load on the valve so that the voltage across the circuit L, C1 will be prevented from increasing by the increase in current and the consequent voltage drop in the internal impedance of the valve. Reference has been directed by the Comptroller to Specification 560,780.

Abstract: 1467160 Carbonising I W S NOMINEE CO Ltd 9 April 1974 [25 April 1973] 15710/74 Headings D1B and DIP A substrate of wool and/or non-carbonisable synthetic fibres and containing natural or regenerated cellulose materials (e.g. present as impurities) is carbonised by treatment at normal or elevated temperatures with a substantially water-free solution of an anhydrous hydrogen acid, e.g. hydrochloric acid or trichloroacetic acid, in an inert organic solvent, e.g. an aliphatic or chlorinated hydrocarbon optionally admixed with trioxane, the treated substrate being subsequently dried, e.g. at up to 150C. The impurities may be removed by beating the substrate followed by neutralisation if necessary and rinsing. The process may be carried out in two stages by impregnating the substrate with the solvent and then treating with the anhydrous acid: perchloroethyleneimpregnated wool may be saturated with hydrochloric acid gas, for example. Unscoured, sized or dirty wool may be treated whereby the wool is degreased, desized and cleaned simultaneously with carbonisation. A dyeing process, e.g. using Alizarin Sky Blue R may follow the carbonisation process without intermediate rinsing or neutralisation. Wool in top, fabric or flock form or cotton may be treated.

A thread brake for yarn running from the spool 1 of a double twisting device comprises a first thread guide 8 rotatable about the spindle 2, a headpiece 3 having a cylindrical braking surface 4 about which the yarn runs and a second thread guide 9 also rotatable about the axis of the spindle 2. The two guides 8 and 9 (which constantly rotate during draw-off) are biased towards each other by a spring 7 so that increased tension in the thread 10a running from the spool causes the guides 8 and 9 to move apart and lessen the thread wrap on the surface 4 so regulating the tension of the thread 10b running from the guide 9. In another form the yarn 10a from the spool passes through a further guide mounted on the lower flange of the headpiece 3 before passing to the guide 8. In a further embodiment the headpiece 3 is divided into upper and lower parts, the top part carrying the guide 9 while the lower carries guide 8 and the braking surface 4; a helical spring connected between the two parts of the headpiece 3 is arranged about the spindle axis in recesses in the parts, to provide the necessary biasing force between the two guides. The guide 9 which is made of wire has a circular mounting portion which fits into a circular groove in the upper part of the headpiece 3 so that it may be moved relative to the headpiece and the initial degree of thread wrap about the braking surface adjusted; a scale is provided on the headpiece against which this setting may be measured. Pins are provided on the two parts of the headpiece to limit the rotation of one relative to the other.

Abstract: 1356921 Making photographic silver halide emulsions AGFA GEVAERT 19 April 1971 [3 April 1970] 15948/70 Heading G2C [Also in Division B1] In a method of making a silver halide emulsion by mixing together aqueous solutions of a silver salt and a halide respectively in the presence of a protective colloid, the solutions are continuously fed into a passageway over the whole crosssection of which the infed mass is maintained in continuous flow away from the feed point or points to an outlet and subjected therein to forces creating turbulence. Various types of mixing device may be used (see Division B1-2). In a typical embodiment, a silver halide emulsion is formed by feeding reactants via conduits 5 into a mixing chamber 3 provided with a rotor 1 which is helically grooved, the reaction mixture exiting via outlet 7. The rate of feed and/or speed of rotor may be regulated by a control system of which sensor 13 is a part. Grain growthrestraining compounds may be added during or after formation of the grains in the mixing device. Emulsions having a large grain size distribution may be obtained by recycling the initially obtained grains or by further precipitation in one or more similar mixing devices. After ripening, the protective colloid e.g. gelatine may be coagulated and co-precipitated with silver halide in a mixing device, the coagulum may be separated and washed, and then redispersed in another mixing device. Chemical sensitizers may then be added, followed by other adjuvants, before the emulsion is ready for coating.

A guard for a combing machine is interlocked with the setting-on rod and with a supplementary friction device so that the guard cannot be opened until the moving parts have come to rest. The guard 15 is carried by a pivoted arm whose boss has a notch whereby the guard is held closed by an abutment 20. The latter is pivoted at 19 and linked to a lever 22 secured to a shaft 23 having a handle 29. A lever 24 on the shaft 23 is pivoted to a slidable rod 25 which co-operates with a hole in a bracket 27 carried by the slidable setting-on rod 28. The latter cannot be moved unless the guard is closed and locked by the abutment 20, when the rod 25 is in the withdrawn position shown in full lines. Conversely, the bracket 27 prevents opening of the guard until the rod 28 is in the " off " position. The friction device comprises a lever 37 carried by a sleeve 32 which is a running fit on a bush 30 secured to a rotating part of the machine. As long as the bush rotates the sleeve is frictionally urged in a clockwise direction and the lever 37 engages a grooved block 36 on a slidable rod 33 which is thus locked. The rod 33 is pivoted to a lever 35 carried by the shaft 23 so that the abutment 20 cannot be moved until rotation has ceased, when a weight 39 disengages the lever 37 from the block 36 and allows operation of the handle 29 to release the guard. Specification 529,917 is referred to in the Provisional Specification.
