Title: Improvements in the production of artificial silk and like products
IPC: D01D5/04
Filed: 1932-04-04
Abstract: <PICT:0399795/IV/1> <PICT:0399795/IV/2> Solutions of cellulose acetate or other cellulose derivative are extruded into a current of evaporative medium, and, in the vicinity of the spinning orifices, there is introduced a current of additional evaporative medium from the external atmosphere, this additional current being induced by heat.  The additional current may be superimposed upon a current of evaporative medium flowing with or against the filaments, and it may be introduced symmetrically or from one side, inside or outside of the bundle of filaments, and at different levels.  The temperature of the additional medium may be less than that in the main body of the cell and the additional medium may be prevented from entering the zone surrounding the spinning solution supply pipe or filter.  The air current induced by heat and drawn from the external atmosphere may be mixed with solvent vapours or with non-solvent vapours, by passage through a vessel containing liquid or loosely packed with porous material saturated with liquid, or steam may be injected into the vessel.  The means for heating the additional evaporative medium may be the same as or additional to that for heating the main body of the cell.  As shown in Fig. 2, a spinning jet 6 is placed in a cell 5.  Evaporative medium passes in countercurrent to the direction of the filaments through a valve 11, and additional medium enters through the valve 14 into a chamber 15 from which it issues in the vicinity of the spinning jet.  The rising current of hot air is induced by steam pipes 17. Evaporative medium is withdrawn from the cell through pipes having valves 18, 19.  A baffle plate 21 is provided for maintaining the atmosphere in the vicinity of the dope supply pipe 27 at a higher temperature than that in the region of the jet.  As shown in Fig. 3, the main current of evaporative medium enters the cell 5 through the pipe and valve 11, while additional medium is introduced through two vertical conduits 24, 25 positioned in proximity to steam pipes 9, heat from which produces a rising current of air in the conduits.  Evaporative medium leaves the cell through a pipe and valve 19.  Specifications 325,233, [Class 2 (ii), Cellulose &c.], 341,075, 396,792, and 399,822 are referred to.

Title: Improvements in and relating to speedometers
IPC: G01P3/46
Filed: 1927-04-07
Abstract: 274,420. Burstyn, W. July 17, 1926, [Convention date]. Electric speed indicators.-In a speedometer of the type in which a dynamo-electric generator is driven from the shaft the speed of which is to be measured, and a current meter functions as the speed indicator, the generator is arranged so that the voltage of the alternating current produced, which is subsequently rectified, has zero value for a finite part of the period. Fig. 5 shows an arrangement in, which the pole-pieces p, q of the permanent magnet N, S are formed with grooves n to secure this result. In Fig. 6, grooves m are provided in addition to the grooves n in order to avoid disturbance by eddy currents. The windings may be arranged upon the armature a or within the grooves m or upon the polepieces p, q. In Fig. 7 the armature is built up of inclined elliptical plates, and the coil s is mounted in a groove m. The commutator may be arranged to give sudden make and break by stepping the contact segments z as shown in Fig. 8. The transmission mechanism may be arranged to drive the spindle x of the armature always in the same direction. As shown in Fig. 9, the spindle carries two toothed wheels u, v coupled to it by free-wheel clutches. The first wheel meshes with a wheel b which is in gear with a driven wheel t, and the second wheel meshes directly with the wheel t. The time constant of the circuit is maintained low so that the current will fall to zero before the expiry of the period of absence of voltage.

Abstract: 794,339. Extruding. INNSWORTH METALS, Ltd., and DOWTY, G. H. July 5, 1955 [April 5, 1954], No. 9934/54. Class 83 (4). An impact extrusion press comprises a frame 11 having a fixed die support 16 and a movable ram carrier 17, a resilient telescopic device 22, 23 interposed between the press frame and the carrier 17, and power-operated mechanism 27 arranged to compress the resilient telescopic device and build-up stored energy therein which stored energy is released during extension of the resilient telescopic device to effect the extrusion operation. The resilient telescopic device is preferably a liquid spring comprising a cylinder 23 mounted on a transverse pin 24 in the press frame, and a plunger 22 connected to the extrusion ram carrier 17. The liquid spring is compressed by a pair of hydraulic jacks 27 disposed one on each side of the press and whose piston-rods 28 are each connected through a lost-motion connection 31, 34 to a bell-crank lever 33 pivoted at 32 to the press frame. The other arms of the bell-crank levers are connected at 35 to toggle links 36 connected to trunnions 37 extending from the carrier 17. When the jacks are operated, the toggle linkage 33, 36 is moved into in-line position, thus compressing the liquid spring, and after passing over the dead-centre position the liquid spring extends rapidly to effect the impact extrusion operation. The lost-motion connection 31, 34 permits the liquid spring to extend without affecting the hydraulic jacks, but the latter are then energzied to take-up the lost-motion and again compress the liquid spring whereby each stroke of the hydraulic jacks produces a compression of the liquid spring. The extrusion tools, Fig. 3, comprise a housing 44 secured to the die support 16 and adapted to receive a metal billet 54 and an extrusion ram 52 and mandrel 51 which are connected through an attachment plate 53 to the carrier 17. The extrusion die is provided on a spigot member 47 having an interrupted thread for rapid engagement in an interrupted threaded bore in the housing 44. The billet 54 is cold impact extruded between the mandrel 51 and the die to form a tube. The liquid spring 22, 23 is adjustable for controlling its rate of extension and hence the impact force. The press frame is built up of side-plates and base-plates.
