Title: Mixtures of level-off d.p. cellulose with aqueous media
IPC: D06M15/05
Filed: 1960-08-29
Abstract: The process of the parent Specification (wherein aqueous dispersions of cellulose are produced by mechanically disintegrating "level-off D.P. cellulose" in an aqueous medium) is modified in that the composition comprising the cellulose and an aqueous medium contains 30 to 90% by weight of the cellulose and may therefore range in consistency from a relatively soft solid to a crumbly free flowing dry-appearing material instead of being a liquid dispersion.  The mechanical disintegration may be such that at least 1% by weight of the disintegrated cellulose has a particle size not exceeding 1 micron.  The mixture may be diluted with an aqueous medium to form a dispersion or a gel.  The level-off D.P. cellulose may be initially wet and may be dried before the mechanical disintegration step by displacing the water in the cellulose by a low boiling water-miscible organic compound and then evaporating off the organic compound. Alternatively the initially wet cellulose may be freeze-dried after the mechanical disintegration step by either of the above methods.

Abstract: 938,480. Removing articles from shafts. DE HAVILLAND ENGINE CO. Ltd. Aug. 29, 1961 [Aug. 29, 1960], No. 29762/60. Class 61. [Also in Group XXIV] A method of separating the component parts of an assembly, including inner and outer members assembled by a substantially linear movement and making a tight press fit with one another, consists in delivering fluid under pressure to a pressure chamber to cause relative linear movement in the direction required for disassembly. As shown the invention is applied to a bearing assembly to facilitate the drawing of the ball bearing 5 from its shaft 1. The shaft 1 passes through an aperture in a casing 2 which is formed integrally with a cylindrical hollow boss 3. The outer race 6 of the ball bearing 5 is secured in an annular recess in the boss 3 by an annular cover plate 7. A nut 8 engaging a screwthreaded portion at the front end of the shaft locks the inner race 4 against the forward end of a spacer element 9, the rear end of the spacer engaging a fixed disc 11 on the shaft. The element 9 has an outwardly projecting annular flange 12 lying within the boss 3, the rear face of the flange 12 being engaged by a carbon sealing ring 13 attached to a bellows 14 which is connected to the casing 2 to form a fluid-tight seal. An annular pressure chamber 21 is formed between the annular face at the end of the enlarged part 15 of the shaft and the annular face of the rear side of the inner flange 18 on the spacer element 9. The spigot portion of the shaft has a central drilling 22 leading inwards from the front end and provided with a series of radial drillings 23 communicating with the pressure chamber 21. A removable screw plug is provided to close the centre drilling. The plug 24 is withdrawn and the lock nut 8 and cover plate 7 are removed prior to delivering fluid under pressure to the centre drilling 22. The pressure in the expansible chamber 21 creates opposing forces acting in an axial direction between the shaft and spacer element, the force on the spacer element being transferred directly to the inner race 4 of the bearing.

Abstract: 213,629. British Cotton Industry Research Association, and Oxley, A. E. Nov. 1, 1922. Testing yarns a n d threads.-The machine iipplies a cyclical variation of stress to a length o f thread suspended therein. The stress may be applied mechanically or electromagnetically, and means are provided for indicating or recording the strain,. and for preventing untwisting of the thread. Fig. 1 shows an arrangement in which the test piece of thread 1 is suspended from a clamp 2 and carries an armature 3 adapted to be attracted by an electromagnet 4 excited by a variable or alternating current. When the armature contacts with the magnet a. circuit is closed which energizes a magnetic clutch 12 for the purpose of raising slightly the rod 8 carrying the clamp 2. A screw-threaded part of the rod 8 passes through a nut in the bearing 9, and a worm wheel 23, Fig. 3, on the rod meshes with a worm on the shaft 18 on which is mounted the armature 17 of the magnetic clutch. The part 13 of the clutch., which is supplied by current through rings 24. is mounted on a shaft 14 which is rotated continuously by gearing 15, 16. In operation, stress is applied repeatedly by the electromagnet 4, and extension of the thread is taken up when the supporting rod 8 is raised slightly by the gear controlled by the magnetic clutch. For measuring the extension of the thread, the worm wheel 23 mav have graduations on its upper surface, a vertical scale 26 being provided. Fig. 7 shows a modification in which the rod 8 is rotated intermittently by spur gearing 37, 38 from the shaft 14 through the magnetic clutch 12. The gear 38 carries a pencil 39 arranged to make a moving strip of paper 40 and so produce a record. The bar 28 to which the clamp 2 is secured slides through a member 29 in which rotation is prevented by a feather, and is connected to the rod 8 by a swivel joint 7. Fig. 6 shows a modified arrangement of the electromagnet for applying the stresses. The electromagnet 4 is excited by a continuous current, and to the end of the thread is clamped an insulating plate 31 which carries a solenoid 32 excited by an alternating current. Contacts 11 control the magnetic clutch, and wings 34 and stops 35 prevent untwisting of the thread. The stresses may be applied mechanically as shown in Fig. 9. The test pieces are supported by slides 51 which are reciprocated by connecting rods 49 and cranks on a rotating shaft 46. Weights 55 are suspended from the lower .ends of the threads by bi-filar suspensions passing through guide tubes 57 in order to prevent untwisting of the threads. The cyclical variation of tension in the test pieces is produced by the inertia of the moving weights. When a test piece breaks, its weight 55 falls on a spring-pressed stud 61 and completes the' circuit of a cut out device which stops the driving motor. _
