Title: Improvements relating to the preparation of blended fibrous materials
Inventor: HUNTER WILLIAM ALDRED
IPC: D01G21/00
Filed: 1952-05-16
Abstract: 735,172. Opening and blending fibres. T.M.M. (RESEARCH), Ltd. Feb. 17, 1953 [May 16, 1952], No. 12503/52. Classes 120(1) and 120(3). Blended fibrous material is continuously prepared by (a) subjecting each ingredient of the blend separately to an opening operation, (b) conveying each such opened ingredient separately to a gravity feed trunk reserved for the said ingredient in quantities calculated to maintain a constant head of material therein, (c) discharging the ingredient from each trunk at a metered rate to a continuously travelling conveyer common to all trunks, the material being transferred to the conveyer under conditions in which the conveyer receives a substantially homogeneous blend of the material by receiving successively a substantially uniform dispersion of tufts of each ingredient, and (d) removing the resultant blend of ingredients from the conveyer. As shown, a separate opener A as described in Specification 735,173 is provided for each ingredient which is conveyed from its opener through a pneumatic duct A<SP>5</SP> to a separate unit comprising a condenser B<SP>2</SP> and a feed trunk B3 forming part of a blending apparatus B constructed as described in Specification 706,043, the rate of discharge by the opener being automatically regulated by means of a photo-cell B<SP>4</SP> to maintain a constant head of fibres in the trunk. Each trunk B<SP>3</SP> discharges at a predetermined rate through variable-speed metering delivery rollers B<SP>5</SP> to a high-speed spiked lattice B<SP>6</SP> which thereby receives a substantially homogeneous blend of fibres. The blended fibres are stripped from lattice B<SP>6</SP> at B<SP>7</SP> and subjected to further opening in a machine C such as is described in Specifications 670,827 or 715,413 followed by a machine D such as is described in Specification 650,157, fed by a gravity feed trunk D<SP>2</SP>, the resultant fleece being calendered at E<SP>1</SP> and wound at E. When dealing with synthetic staple fibre, machine C and/or D may be omitted. The opening action performed at A is regulated, by adjustment of the relative speeds of feed mechanism A<SP>2</SP> and lattice A3, so that all the ingredients are presented to the blending stage in substantially the same degree of openness ; where. the raw material is cotton or other natural fibre in baled condition, one or more supplementary preparatory opening and cleaning stages may be desirable. Reference has been directed by the Comptroller to Specifications 670,827 and 706,043.

Abstract: 786,218. Automatic voltage regulation. WAGNER ELECTRIC CORPORATION. May 3, 1955 [May 13, 1954], No. 12779/55. Class 38 (4). [Also in Group XXXIX] The output voltage of a transformer is maintained constant with variations in load or supply by injecting the output of a bridge network, comprising saturable reactors responsive to the said variations, into the input or output circuits of the transformer. The transformer 12 comprises a secondary winding 14 and a primary winding 16, 18 whose induced voltage E is to be kept constant with variations in the supply voltage V1. A compensating winding 20 supplies a bridge network 30 having its output e injected into the primary circuit and comprising opposite pairs of saturable reactors 32, 36 and 34, 38, the reactors in each pair having substantially equal impedance as determined by series-connected D.C. control windings (not shown) for each pair. In operation, the phase and magnitude of the compensating voltage e relative to the supply voltage V1 is determined by the relative impedance of the reactor pairs, the latter in turn depending on the D.C. control currents whose magnitudes are determined by an electrical characteristic of the load or supply. The D.C. control currents may be manually set by potentiometers, Fig. 1 (not shown), and the control windings may be replaced by a manually set core. The opposite pairs of reactors may comprise a single three-legged core having two A.C. windings and a single D.C. control winding. In modifications, Figs. 6-10 (not shown), (1) the bridge is supplied from a second transformer whose primary is connected across the secondary 14 or across the supply voltage V1; (2) the bridge is connected in the secondary circuit of transformer 12 and is supplied from a compensating winding on transformer 12 or from a second transformer whose primary is supplied from the secondary of transformer 12.

Abstract: 624,405. Pneumatic guns. JAMESON, J. L. Sept. 16, 1942, No. 13096. [Class 92 (ii)] A gun comprises a chamber in which fluid pressure is built up and which has an outlet in line with the barrel and opening directly to the interior of the chamber, and means to clamp a diaphragm across the opening, the arrangement being such that the diaphragm shears from its clamping means and thus allows the application of pressure to a projectile in the barrel when the fluid pressure in the chamber reaches a predetermined value. In the construction shown, bullets 2 are fed down a shoot 23 to an oscillating breech-block 24 which is fitted with pawls adapted to impart a step-by-step movement to a metal strip 28 fed from a spool 29. A small section of the strip provides a temporary closure for the forward end of a cylinder 4 supplied with fluid under pressure by a pipe 18. The fluid is further compressed in the cylinder, ultimately to fracture the section of the strip 28 and thus to expel a bullet, by a plunger 4<SP>1</SP> driven by a ram 7 in a cylinder 8. Oil under pressure for driving the ram is fed to the cylinder 8, under the control of a piston valve 9, by a pipe 10. The movements of the piston valve are controlled by a relay piston 11 driven by a fluid supplied via a valve 17. The latter carries spaced abutments 14, 15, which are engaged by an abutment 12 fitted to an extension 13 of the ram 7. In modifications, the plunger may be driven by a steam engine, an internal-combustion engine, or an electric motor. In the case of an internal-combustion engine, the piston thereof is connected to the plunger, both being drilled to provide a passage for leading some of the gases from the engine to the cylinder 4.
