Title: Improvements relating to electrostatic apparatus for the separation, by ionisation, of particles in suspension in a fluid
IPC: B03C3/74
Filed: 1931-03-24
Abstract: <PICT:0368091/III/1> <PICT:0368091/III/2> <PICT:0368091/III/3> <PICT:0368091/III/4> <PICT:0368091/III/5> Electrostatic apparatus for the separation of suspended particles in a fluid consists of a plurality of discharge electrodes and a plurality of rotating collecting electrodes so arranged that the rotatable electrodes pass through a zone in which the electrostatic field is removed or reduced to facilitate the removal of dust therefrom.  In the arrangement shown in Fig. 3, the discharge electrodes 2 are suspended between disc-like collecting electrodes 3 which are rotated about the axis 5. The gas stream flows across the faces of the discs and at rightangles to the electrodes 2, which are not adjacent to the lower parts 6 of the electrodes 3, thus allowing the dust to fall into the hopper 7. Scrapers 8 may also be provided.  A modification is shown in Fig. 4, in which the discharge electrodes 2 consist of two series of arched strips.  In both these arrangements, the direction and speed of rotation of the discs 3 may be altered so that the speed of the gas stream in relation to the electrodes may be high or low depending upon the ease or difficulty with which the particles are separated. As shown in Fig. 7 the collecting electrodes consist of concentric cylinders 3, having fixed discharge electrodes 2 between their surfaces, which rotate about the pivot 10.  The discharge electrodes are omitted from a portion of the periphery of each cylinder, leaving a space 11 wherein the dust falls readily into a suitable hopper underneath. In the embodiment shown in Fig. 9, the collecting electrodes consist of tubes 3 each having a central discharge electrode 2 fixed in relation to the tubes 3, and the whole system is rotated about the axis 13.  The current to the discharge electrodes is supplied through a contact strip 14 (see Fig. 10), so that the discharge electrodes passing across the segment 15 are not supplied with current, thus allowing the dust on the collecting electrodes to fall into a hopper 16 arranged below.  The Specification as open to inspection under Sect. 91 (3) (a) also describes an arrangement in which the collecting electrodes consisting of two endless travelling bands arranged on opposite sides of the gas conduit and having a series of discharge electrodes arranged between them.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to seals for packages
IPC: G09F3/03
Filed: 1950-04-12
Abstract: 691,533. Seals. STOFFEL, H. F. April 12, 1950. [April 12, 1949] No. 9064/50. Class 146 (ii). In a seal device comprising a U-shaped member whose limbs are adapted to be closed and automatically locked together,. an inturned flange 16 is provided at the end of one limb 10, and a tongue 18 set at right angles at the end of the other limb 11, the tongue 18 being adapted to engage in a transverse slot 17 in the flange 16 when the limbs are closed together and to be bent towards the flange 16 by engagement with a curved surface 22 of the limb 10 behind the slot 17. The tongue 18 has a shear cut or slot 20 producing a catch 21 which is bent out of the plane of the tongue by the curved surface 22, thereby preventing retraction of the tongue 18 after it has entered the slot 17. The bending takes place along line 23 which may also be weakened by impression. To ensure that the sections 10, 11 are pressed together sufficiently to bend the catch 21 to lock them together, a snap 24 is provided near the base of the tongue 18. This snap 24 extends farther to the left than slot 17 so that, in closing, the section 11 is sprung out of place laterally and springs back with a, snapping sound after the snap has passed through the slot. Weakened lines 25 are provided so that when opening is attempted by inserting a tool between end portions 26 and flange 16 a tear is produced on one of these lines. To attach the seal to the binding element the latter is inserted between the open jaws to a position near the line of fold 12. The binding element may be cord, ribbon, or stranded wire and, if tied together, the knot is encased within the box formed by side walls 14, 19 of the seal.

Title: Evaporating caustic soda solutions
Inventor: SOLVAY CIE
IPC: C01D1/42
Filed: 1946-03-25
Abstract: Solid caustic soda containing less than 1 per cent water is obtained from an aqueous solution containing between 80 per cent and 95 per cent NaOH by exposing a surface area exceeding 10 and preferably 100 square metres per ton, of the solution at a temperature between 200 DEG  and 300 DEG  C. to a gas or vapour in which the partial water vapour pressure is kept below 600 mm., under adiabatic conditions or under such thermal conditions that not more than 80 ton calories are gained by the system, or not more than 40 ton calories are lost, per ton of product.  The ideal process, which is both adiabatic and isothermal, is represented by the use of 90 to 92 per cent caustic soda solution at 270 DEG  C. and is an auto-evaporative-crystallization process.  In an example, a 89.5 per cent NaOH solution at 270 DEG  C. is sprayed down a vertical empty tower, 15 feet high, in which the pressure is maintained at 5 lbs. per square inch.  A granular product containing 0.2 per cent water and having an apparent density of 0.4 grams per c.c. is obtained.  In a modification, a 92 per cent NaOH solution at 280 DEG  C. is sprayed down a tower up which air at 250 DEG  C. is blown.  Film evaporation may also be used, employing (a) a heat-insulated ribbon mixer in which the solution is evaporated on the surface of granular caustic soda in a current of air; this gives a coarse sandy product with an apparent density of 0.9 to 1.1 grams per c.c.; or (b) a horizontal drum rotating partly in a bath of 89 per cent NaOH at 280 DEG  C. and partly in the air.  In all cases, the initial starting solution may be prepared in a conventional, forced circulation, tubular evaporator using diphenyl vapour as heating medium.  Specification 612,603 is referred to.

Title: Producing slub yarn
IPC: D02G3/34
Filed: 1972-04-13
Abstract: 1379247 Finishing and heating yarns COURTAULDS Ltd 13 April 1972 [14 April 1971] 9346/71 Heading D1F In a continuous yarn slubbing process, a running thermoplastic yarn drawn between feed and draw rolls passes through a guide which is moved to bring the yarn into intermittent contact with a heater so as to form the slubs and also to provide alternative yarn paths which the yarn follows at random so that the slubs are randomly varied. As shown, yarn following the path 7 and drawn between rollers 1 and 3 is engaged by a freely rotatable pulley 5 carried by a rotating disc 4 to be diverted into periodic contact with, and consequently softened to form slubs by, an electrically heated fixed cylinder 2 and meanwhile to follow randomly alternative paths 9 and 10 across the shoulder 8 and the apex of the pulley groove. The paths provide different lengths of, and tensions in, the yarn contacting. the heater and therefore different stubbing effects.

Title: Improvements in or relating to ball bearings
IPC: F16C29/06
Filed: 1962-03-12
Abstract: 926,119. Bearings. W. SCHAEFFLER, and G. SCHAEFFLER, [trading as INDUSTRIEWERK SCHAEFFLER OHG]. March 12, 1962 [March 10, 1961], No. 9499/62. Class 12 (1). A recirculating ball-type rectilinear motion bearing, through which a shaft moves axially, has an inner surface of an outer member 1 engaging an outer surface of an inner member 4 and the radial distance of the latter surface is greater than the distance from the bearing axis of the centre of the balls. The outer member 1 is made of hardened steel and contains four C-shaped slots 3 therein and the inner member 4 is made of synthetic plastics material or aluminium, for example, and contains four oval tracks therein. The portion of the track which coincides with the C-shaped slot 3 is a groove 5 and the remaining portion of the track is a slot 7. The balls which are in the slot 7 are able to engage both the shaft (not shown) and the outer member 1 and thus carry the load, whereas the unloaded balls are in the groove 5 and extend through the slot 3 in the member 1. The width of the slot 3 is less than the diameter of the balls so that they are retained therein. Ramps 10 are provided to raise the balls from the slot 7 to the grooves 5 and vice versa. Relative rotary movement between members 1 and 4 is prevented by extensions 12, 13 thereon which lock against each other and relative axial movement is prevented by making one member an interference fit in the other. In modifications, the track 7 is inclined relatively to the bearing axis; an additional sleeve of synthetic plastics material for example, is mounted on the outer member 1 to retain the balls in the slots 3, which can be greater in width than the diameter of said balls; and the inner member 4 may comprise a number of segments.

Abstract: 1,139,752. Peeling and roasting groundnut kernels. E. RUSSELL and G. DÍRNBACK. 7 March, 1966 [9 March, 1965; 5 Jan., 1966], No. 9804/66. Heading A2Q. In peeling and roasting groundnut kernels, they are kept in motion for a predetermined time in a hot, volatile liquid, such as water at 70 to 85‹C., then removed from this liquid and machine-peeled, as by being passed through the nip between profiled rollers, then dried and roasted in hot, edible oil, e.g. a vegetable oil such as peanut oil at 150 to 170‹C. Finally, excess oil is removed from the roasted kernels. Drying may be effected in an oven, or on a heated belt, or in a stream of hot air, e.g. at 105 to 120‹C., which may be passed upwardly through a moving, perforated belt conveying the peeled kernels to the hot oil. When the peeled kernels are dried in a stream of hot air, any fragments of skin remaining on the kernels are sucked or blown off. Roasting may be effected in a pressure-resisting container, into which water may be sprayed just before completion of roasting, so that the kernels are subjected to steam pressure, which hardens their surfaces. The volatile liquid, roasting oil and/or sprayed water may contain sugar, common salt or spices.

Title: Improvements in or relating to the manufacture of films of regenerated cellulose andother materials
IPC: B29D7/00
Filed: 1950-04-21
Abstract: A plurality of superposed wet films of regenerated cellulose or other hydrophilic material are simultaneously dried by treating the separate films with an anti-adhesion solution or dispersion, assembling a plurality of such treated films in superposition while still wet and introducing such assembly into a drying-machine.  The anti-adhesion solutions or dispersions may be any of the aqueous solutions or dispersions used in the prior art or described in the patent or other technical literature for the treatment of individual films of regenerated cellulose or other hydrophilic material for the purpose of preventing such films from firmly sticking together after they have been separately dried and subsequently superimposed and subjected to a certain amount of pressure as in packaging and storage.  Typical anti-adhesion aqueous solutions and dispersions are said to be the solutions of alkali metal silicates or colloidal dispersions of certain mineral materials described in Specification 386,775 or the dispersions of insoluble organic amides described in U.S.A. Specification 2,206,046.  An example given of an anti-adhesion solution is a 10 per cent by weight solution of glycerine in water containing 0.5 gram of sodium silicate per litre.  Films which have been treated and dried in superposition according to the invention are said to be readily separable on discharge from the drier.
