Title: Improvements in sliver packing apparatus
IPC: B65H54/84
Filed: 1964-04-23
Abstract: A sliver coiler has means to maintain the coiler head 14 in constant and substantially uniform pressure contact with each coil of sliver successively packed into the can 8.  In the embodiment shown the coiler head is vertically movable and rests upon the sliver 40 in the can, while the can is urged upwards by fluid entering casing 42 through opening in turntable 6.  The coiler head has guide columns 12, 13 slidably mounted in bars 3 and 5, and a drive shaft 15 driven by collar 16 to rotate the tubewheel and calender rolls.  In modifications the sliver can may rest on turntable 6 and have a bottom slidable therein and urged upwards by the fluid pressure, or the desired pressure may be obtained merely from the fluid pressure with the coiler head being fixed, or merely from the coiler head with the sliver can and the bottom thereof being fixed.  When fluid pressure is used it is increased during coiling to maintain a uniform pressure between the uppermost sliver coil and the coiler head.  The coiler head may be lifted and lowered hydraulically or pneumatically.

Title: Electromagnetic and armature core tubes for the same
IPC: H01F7/08
Filed: 1974-04-18
Abstract: 1499326 Casting composite articles EXPERT INDUSTRIAL CONTROLS Ltd 9 April 1975 [18 April 1974] 16898/74 Heading B3F [Also in Division H1] In an operative solenoid a cylindrical armature is slidable in a cylindrical core tube having two sections of magnetizable material separated by a section of non-magnetic material, e.g. brass. The core tube is formed by machining the magnetizable parts to shape and locating them in a mould, after which their ends are induction heated, the mould and components are spun, and molten brass is poured into the tube, which is thrown centrifugally into the gap between the magnetizable parts and allowed to solidify under rotation. The complete tube is removed and surface machined. The mould surface may be defined by an extension of one magnetizable part to fit over the other, which is removable in machining. Alternatively a magnetizable tube is machined with a circumferential recess in its outer periphery apertured to the interior, which is covered by a further external tube enabling brass to be centrifugally cast into the recess after induction preheating. The tube is machined externally and internally, during which the magnetizable bridge underlying the brass and the external tube are removed. The recess may be internally machined leaving an external web or bridge replacing the external tube. Alternatively the tube may be machined from the solid leaving a baffle at one end to prevent egress of brass during casting. The presented ends of the magnetizable parts may be profiled in machining to produce desired operating characteristics, e.g. armature displacement proportional to current.

Title: Conjugate spinning of acrylonitrile filaments
Inventor: OHFUKA TOSHIO
IPC: D01D5/30
Filed: 1969-04-01
Abstract: 1,216,786. Conjugate spinning acrylonitrile filaments. ASAHI KASEI KOGYO K.K. 1 April, 1969, No. 17051/62. Heading B5B. [Also in Division D1] In a process for the production of conjugate acrylic filaments, at least two polymer components, each containing at least 50% by weight of acrylonitrile and one component having a higher acrylonitrile content and heat contractibility than the other(s) are spun from nitric acid solution, into a coagulating bath, the filaments are stretched at an elevated temperature, dried in the stretched state, heat treated in the tensionless state at a temperature between 98 and 150‹ C., preferably 110‹ to 140‹ C., and finally stretched at a temperature between 90‹ and 260‹ C. After drying the filaments may be subjected to treatment with hot water, especially at above 60‹ C. Final stretching is suitably effected to a draw ratio of from 1À25 to 3À0 especially 1À35 to 2À5. Both conjugate and sideby-side filaments may be spun, conjugate ratios of 60/40 to 40/60 by weight being preferred. In a typical example a first copolymer composed of 92% by weight of acrylonitrile and 8% by weight of methyl acrylate and a second copolymer composed of 90% by weight of acrylonitrile and 10% by weight of acrylamide are separately dissolved in 67% by weight nitric acid of - 5‹ C. to give a 16% by weight solution. These solutions are fed in equal quantities to the same spinneret to produce a side-by-side conjugate filament. The extruded filament was coagulated in 30% by weight nitric acid, rinsed with water, subjected to a 9-fold stretching in a water bath at 98‹ C. and dried. The filaments so prepared were then crimped by treating with saturated steam at a temperature between 100‹ and 133‹ C. in the tensionless state for 10 minutes. Finally the filaments were heat stretched at temperatures of between 110‹ and 140‹ C. to a draw ratio between 1À15and 1À39. Spinnerets suitable for the spinning of the conjugate filaments are shown in Figs. 1 and 3. In Fig. 1 the solutions of the two components are delivered to the annular spaces 14 and 16 from which they are delivered separately to the chamber 21. The spinning jets are placed so that extrusion occurs at the interface of the spinning solutions. Ternary conjugate fibres (Figs. 6A, 6B and 6C, not reproduced) are produced by the spinneret shown in Fig. 3 which works on the same principle as that described above. A number of variations on the technique and a list of suitable copolymers are given in the Specification.

Title: Improvements in the bearings of spinning spindles
IPC: D01H7/04
Filed: 1925-07-03
Abstract: 243,271. Br³hl, P. July 3, 1925. Roller bearings.-In a bearing for spinning spindles in which rollers f bear directly on the spindle d, the rollers are guided axially by collars h, i rigidly secured to the spindle so that when the spindle is withdrawn from the bearing casing it carries the rollers with it. As shown in Fig. 1, the rollers are carried by a cage q having an annular upper part r and downwardly extending fingers s separating the rollers. A spring ring t in the lower end of the cage prevents the rollers from falling out when the spindle is removed from the casing. The outer surface of the collar h is tapered to facilitate the passage of lubricant up the spindle to the rollers. Excess of lubricant passes over the top edge of the casing e into an annular groove u and down a passage (not shown), in the tube a to the interior thereof and from thence through a hole w to the spindle. In a modification, in which a roller spacing cage is not used, the collars h, i, Fig. 8, are increased in diameter so that the distance l between the outer surface of the collar h and the inner surface of the wheel g, which is fixed to the spindle, is less than the diameter of the rollers. To assist the rollers into the operative position when replacing the spindle the upper edge n of the casing e is tapered. In another modification the bracket e, Fig. 11, receives an outer bearing race-ring z which, when the spindle is removed. is carried away by the collar h.

Title: Improvements in or relating to the insulation of electric cables or apparatus
IPC: H01B9/06
Filed: 1939-06-13
Abstract: 530,577. Electric cables and insulation. STANDARD TELEPHONES & CABLES, Ltd., SCOTT, T. R., and WARNER, A. J. June 13, 1939, No. 17284. [Class 36] In electrical apparatus, such as cables, condensers, terminal bushings of transformers &c. in which the insulation includes a liquid halogen derivative of the aromatic hydrocarbon group and solid material, the solid material comprises styrene co-polymerized with between .005 and 25 per cent. of para-divinyl-benzene, with or without plasticizers, to minimize solution of polystyrene in the halogen derivative; with chlorinated diphenyl, 1 to 10 per cent. of para-divinyl-benzene is desirable. In a condenser of wound or stack form, the electrodes of which are separated by solid insulating material, the whole being immersed in such a halogen derivative, the solid material comprises one or more sheets or tapes of the copolymerized material, or of fibrous material impregnated with the materials which are then co-polymerized by heat. In terminators for cables, such as cables insulated with lappings of fibrous material impregnated with polystyrene, the spaces between the lappings being permeated with cable compound, the admixture may be fed into the insulation at the cable end, as through tappings in the sheath, and polymerized in situ, or fibrous material impregnated with the co-polymer may be used to build up the end insulation, and basted at intervals during the building up as in Specification 504,720 ; the termination may include stress grading devices with similar insulation. Rubber, rubber plasticizers such as ceresin wax, plasticizers for polystyrene such as phenanthrene, fluorene, isoamylnaphthalene or other homocyclic carbon compound having two or three fused rings, a boiling point higher than 240‹C. and a low electric moment, or other polymers such as polyisobutylene or polyethylene may also be added.

Abstract: 1294015 Electro-physical measurements AGFA-GEVAERT N V 19 April 1971 [14 April 1970] 17752/70 Heading G1N [Also in Division H3] An induction flowmeter has the output voltage a 1 , a 2  from the measuring electrodes 87,88 applied to a preamplifier circuit including four operational amplifiers connected so as to increase the suppression of common mode signals and have a high input impedance. The liquid to be measured flows through an insulating tube passing through a laminated magnetic core, Fig.1 (not shown) provided with facing poleshoes around which are wound two series connected coils for providing an A.C. field at right angles to the flow. Measuring electrodes 87,88 diametrically positioned in the tube wall are connected respectively to the non- inverting inputs of feedback operational amplifiers 10,11 the outputs of which are connected to the differential inputs of feedback amplifier 12. The inverting inputs of amplifiers 10,11 are interconnected by series identical resistors 24,25 the node of which is at the common mode voltage and is fed back via voltage follower amplifier 13 to the non-inverting inputs of amplifiers 10, 11. Thus for the common mode voltages i.e. a 1 =a 2  both differential inputs of amplifiers 10, 11 are at equal voltages and no current flows through resistors 24, 25, 20 and 21. The common mode voltage is transmitted with an amplification factor of 1. However the differential mode voltage a 1 -a 2  gives rise to a current flow through resistors 24 and 25 and resistors 20, 21 resulting in an increase in common mode rejection by a factor A=(1+R 20 /R 24 ) where A is the amplification factor of the respective amplifiers 10, 11. The input inpendance to the amplifer for common mode signals is high due to the apparent impedance of resistors 22, 23. However by connecting resistors 22,23 to voltage dividers 30-28, and 31-29 as shown the input impedance for the differential mode signals can also be made high. To prevent parasitic oscillations the leads from the measuring electrodes are shielded and capacitors 54, 55 connected as shown. Deviation of the rate of flow may be measured by comparing the output of the preamplifier in a differential amplifier with an integrated signal representative of the magnetic flux which actually passes through the liquid between the two measuring electrodes and which is obtained from a measuring coil placed between the pole pieces and insulating tube. The output of the differential amplifier is synchronously demodulated, Fig.5 (not shown).
