IPC: C25B9/19
Filed: 1916-10-24
Abstract: 102,049. Wheeler, F. G. Oct. 30, 1915, [Convention date]. Alkalies and chlorine, obtaining; cells; diaphragms; electrodes; electrolytes, circulating.- A cell cover is supported independently of a combined cathode and diaphragm, by means of one or more columns or the like. Fig. 1 shows a hollow column 3 narrowed at the middle and fitting into circular grooves in the base 1 and cover 2. Electrolyte is fed through the base 1 within the column and flows out through holes 15 towards the anodes 5. These may be supported by the cover 2. The combined cathode and diaphragm 6 is attached to a ring 8 loosely surrounding the cover. A plastic luting 13 may be provided between the ring 8 and cover, allowing of movement of the ring when the cathode-diaphragm expands or contracts. An outer casing 10 is provided with outlets for alkali and hydrogen. Chlorine escapes through gaps 9 in the top of the column 3. In another arrangement, the hollow column is cylindrical, but flared at its upper end, and makes a liquid-tight joint with the centrally-apertured base so as to form an annular cell. An electrolytesupply pipe, chlorine pipe, liquid-level gauge, and other accessories, such as a feed-reguator, may then be disposed within the central space; or passages for electrolyte and chlorine may be made in the thickness of the wall. The anodes may be attached to bosses on the inner wall constituted by the column, connexion being made by graphite or metal pins through this wall; or the anodes may pass through the base. The outer casing and cathode diaphragm may be secured to a removable ring surrounding the base. In any of these constructions, the column may be integral with the base or cover. The cover may be made in sections. Stoneware, cement compounds, and iron faced with rubber are suitable materials for the parts of the cell. According to the Specification as open to inspection under Sect. 91 (3) (a) the diaphragm may be attached to the cover. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to textile spinning frames
IPC: D01H5/22
Filed: 1947-06-09
Abstract: 653,734. Drawing apparatus for textile spinning machines. MACKIE & SONS, Ltd., J., and MACKIE, J. P. June 9, 1947, Nos. 15147/47, and 14220/48. [Class 120(ii)] A spinning frame for jute or similar long staple fibres spun directly from slivers has a retaining nip and a drawing nip so situated that the straight line joining them is more horizontal than vertical and is so short that if the sliver were to follow it excessive breakage of fibres would occur. To obtain the required length of sliver path, fibre control means which deflect the sliver out of a straight line path are provided. Preferably, the vertical distance between the retaining and drawing nips is no greater than half the length of the sliver path. The improvements make it possible to reduce the height of the machine. In one embodiment, Fig. 2, a sliver S is drawn between rotating rollers 34, 35 and drawing rollers 36, 37 and is deflected to increase its path to a length appropriate to the length of the fibres by a slip-draft roller 38, which is driven slightly faster than the retaining rollers 34, 35. A pressing roller 39, lightly weighted by its supporting arm 54, helps to control the fibres. Retaining roller 35 is weighted by a spring 40 through a bell crank-lever 42 and drawing roller 37 is weighted by a load 44 through levers 46, 48. The sliver S is fed from a can, but the drawing head may be modified slightly to permit feeding from sliver rolls in a creel above the retaining rollers. In a further modification, Fig. 3, two pairs of slip draft rollers 66, 67 and 70, 71 are employed and the retaining rollers 34, 35 are located lower than the drawing rollers 36, 37 so as to facilitate feeding from cans. In an additional modification, in which sliver is fed preferably from rolls, the sliver may enter the drawing head from the front of the machine. Specifications 407,690, 407,707, 509,493, 516,466 and 653,735 are referred to.

Abstract: 750,238. Electrodialysis apparatus. NEDERLANDSE CENTRALE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK. June 1, 1953 [Sept. 23, 1952], No. 15225/53. Divided out of 750,220. Class 41. A method of rinsing at least one of the electrode chambers of an electrodialysing apparatus comprises subdividing the electrode chamber by means of one or more ion permeable diaphragms into an auxiliary compartment bounded by the membrane bounding the electrode chamber, and an electrode compartment bounded by or containing the electrode, with or without one or more intermediate compartments, passing rinsing liquid through the auxiliary compartment so as to contact and rinse the whole surface of the membrane and from thence through the electrode compartment, or in series through the intermediate compartments and the electrode compartment, the direction of flow in each compartment being opposite to the direction of flow in the adjacent compartment, and discharging the rinsing liquid from the electrode compartment. Each electrode chamber of a multicell electrodialysis apparatus (Fig. 1) bounded by an electrode E and a membrane M is divided into an electrode compartment 4 and an auxiliary compartment 5 by a diaphragm 3 of micro-porous rubber or small-meshed polyvinyl chloride gauze. Rinsing liquid is fed into the top of the auxiliary compartment 5, through a perforation at the bottom of the diaphragm 3, and is discharged at the top of the electrode compartment 4. The electrode chamber may be divided into an electrode compartment 4 (Fig. 4), an auxiliary compartment 7, and two intermediate compartments 5 and 6, in which case rinsing liquid is fed into port 7 and passed in series through compartments 7, 6, 5 and 4 and discharged at the top of port 4. In a modification (Fig. 5) the electrode chamber is subdivided into an electrode compartment 4, an auxiliary compartment 7, and two intermediate compartments 5 and 6, and rinsing liquid is fed into the tops of compartments 7 and 5, simultaneously, conducted from the bottoms of these compartments to the bottoms of compartments 6 and 4 respectively and discharged from the tops of compartments 6 and 4. The rinsing liquid may be fed transversely through one or more passageways extending through the diaphragm or diaphragms, and also, if desired, transversely through the electrode.

Title: Improvements in means for interlocking control members or other actuating or movabledevices
IPC: G05G5/08
Filed: 1920-06-08
Abstract: 167,637. Herbert, Sir A., and Harrison, H. T. June 8, 1920. Rods, locking.-An interlocking-device for preventing appreciable simultaneous actuation of more than one of a pluralitv of control members A, A<2>, &c. comprises movable abutments such as balls, rollers, or sliding-blocks B, B<2>, &c., guided across the paths of the control members, and each normally lying, under resiliently applied locating- means such as the spring-pressed plungers D<2>, with its centre in the plane of contact of a pair of contiguous control members, all of which have bevelled faces A<8>, and are substantially of the same thickness as the abutments. When one control member, say A<4>, is operated, its bevels A<8> displace the abutments so that they wholly obstruct the remaining members. In the form shown, balls are contained in a tube C having an aperture C<2> of less width than the diameter of the balls, and through this aperture pass noses A‹ formed on the control members. The plungers D<2> are housed in enlargements C<3> of the tube C and carry rollers D, which, by engaging the shoulders C<4>, limit their inward travel. By extending the ball-carrying tube, the interlocking effect may be produced between members not contiguous.

Title: Apparatus for collecting sheets of paper, cardboard or the like and for conveying away stacks thereof composed of a predetermined number of sheets
IPC: B65H29/51
Filed: 1963-04-19
Abstract: 972,407. Sheet delivery apparatus. A. ERK, [trading as ERK-MASCHINENBAU DR. ING. A. ERK]. April 19, 1963 [April 27, 1962], No. 15471/63. Heading B6H. Apparatus for collecting sheets of paper comprises a collecting cylinder 2, endless belts 9 cooperating with the cylinder 2 for holding the sheet being collected against the periphery of the cylinder, variable speed drive means 11, 12 and 13 for the endless belts 9, a feeding and discharge guide 3 for guiding the sheets on to the cylinder one by one and off the cylinder in stacks, and control means for controlling the number of sheets collected on the cylinder and the discharge of the associated sheets therefrom. Continuous belts 7 feed sheets cut from a continuous web by a rotary cutter 8, to the collecting cylinder. A photo-electric device 14 detects any misplacement of sheets on the cylinder 2, and regulates the gearing 13 via a servomotor (not illustrated) to vary the slip of the belts 9 to align the sheets collected. In the embodiment shown in Fig. 1, the control means includes a cam disc 19 coupled for rotation with the cylinder 2 and a counting mechanism 6. In operation, when the guide 3 is in the feeding position, Fig. 1, an electromagnet 22 is energized keeping a cam follower or roller 18 out of contact with the cam 19. When the last sheet collected has been sensed by a photoelectric device 24 and counted, the mechanism 6 de-energizes the magnet 22 by operating a switch 23, and roller 18 is brought into contact with the cam 19 by a compression spring 20. This enables the guide 3 to be moved into the discharge position as soon as the roller 18 rolls off the raised portion 25 of the cam 19. The switch 25 is operated only briefly during the time the raised portion 25 and the roller 18 will co-operate, but due to the increased air gap, the armature 21 of the magnet 22 is not attracted to raise the roller 18 from the cam 19 until itco-operates again with the raised porttion 25. The guide 3 is then moved to the feeding position and maintained there. In a second embodiment, Fig. 2 (not shown), the magnet 22 and armature 21 are placed by electromagnetically operated bolt to maintain the roller 18 out of contact with the cam 19. Also, the counting mechanism may be operated by the collecting cylinder co-operating with an inductive impulse giver 29. In a third embodiment, Fig. 3, the counting mechanism 6 is coupled to the shaft 1 of the cylinder 2 and closes a switch 40 after a certain number of revolutions of the collecting cylinder 2. This completes a circuit from a source 33 by a brush 32, slip rings 31, contact 35 and lead 38 through a solenoid 37 which in turn moves the guide 3 to the discharge position and closes a switch 41. The guide 3 is not returned to the feeding position by compression spring 20 until the circuit is completed through an electromagnetically operated bolt 45 via contact 35a and lead 39.

Abstract: 476,225. Mine props. GRIFFITHS, E. E., and BATRGATE, R. A. June 3, 1936, No. 15484. [Class 20 (ii)] A telescopic pit-prop is adapted to give a constant resistance to collapse by deformation of an easily renewable member positioned between the movable parts of the prop. In one form, Fig. 1, the prop comprises channel-shaped members 20, 21, slidable one within the other, the outer member 20 having welded to it, stiffening collars 22, 23, acting as guides for the upper member 21. A cross-pin 26 on the upper member is supported in a loop of a deformable member 25 fixed at one end to the lower prop member and bent upwardly about the cross-pin, to bear against the web of the upper prop member, so that movement between the pit-prop members is resisted by the constant resistance of the member 25 to deformation. In another form, Fig. 5, multiple cross-pins 26, which may be in staggered formation, bear against bends in a strip 25 secured at its upper end to the lower prop member, while in yet another .form, Fig. 8, an H-section bar 21 slides in a hollow rectangular tubular member 20, and deformable elements 25 are disposed on each side of the web of the section bar. Fig. 10 shows an arrangement of props as supports for a mine arch 39, 40, having angles 43 to bear upon the upper ends of the collapsable props at each side.
Patent GB-722055-A (GB)
Title: Process for preparation of alkyl titanates
IPC: C07F7/00
Filed: 1952-06-19
Abstract: Alkyl titanates are prepared by admixing an aliphatic alcohol having at least 2 carbon atoms in the molecule, titanium tetrachloride, ammonia and a nitrogenous liquid consisting of an aliphatic amide or nitrile containing not more than 3 carbon atoms per nitrogen atom, thereby forming a liquid alkyl titanate and ammonium chloride and separating by gravity or centrifuging the liquid alkyl titanate from the nitrogenous liquid of different density and the ammonium chloride.  The nitrogenous liquid is normally used in amount sufficient to dissolve the ammonium chloride or form a slurry therewith.  The preferred nitrogenous liquid is formamide, in which ammonium chloride is soluble, or one which is denser than the alkyl titanate whereby the latter forms as an upper layer on a layer of the nitrogenous liquid and solid ammonium chloride.  When the alkyl titanate is the denser liquid, an inert organic solvent of low density, e.g. petroleum ether, which is miscible with the titanate and immiscible with the nitrogenous liquid may be added whereby a solution of titanate and solvent forms the upper layer.  Such a solvent may also be added when the reaction mixture has an inconveniently high viscosity. The reaction is preferably carried out by first mixing the titanium chloride with the alcohol in excess; some reaction occurs and the hydrogen chloride formed may be removed, e.g. by sweeping out with an inert gas such as air; the ammonia and nitrogenous liquid are then added.  If desired, the nitrogenous liquid may be added before the sweeping-out treatment.  Generally, ammonia is passed into the reaction mixture to keep the mixture saturated therewith.  Titanates may be so formed from C2-20 alcohols especially the primary and secondary unsubstituted alcohols.  The titanates may be used as modifiers for paint, vehicles, resins and thermoplastic compositions.  Examples describe the production of titanates of 2-ethyl butanol, n-butanol, isopropanol and octadecanol thinned with petroleum ether using, as nitrogenous liquids, formamide, dimethyl-formamide, oxydipropionitrile, iminodipropionitrile or adiponitrile.

Title: Process for Preserving Green Fodder.
IPC: A23K3/03
Filed: 1917-10-31
Abstract: 120,256. Marks, E. C. R., (Reinhardt, C.). Oct. 31, 1917. Ensilage.-Relates to a process for preserving green fodder in a sweet condition in containers of usual construction having means for applying a variable pressure to the contents. The fodder is placed in the container in layers of about one and a half metres in thickness. The first layer, which is partially dried in the air, is allowed to ferment until it reaches a temperature of 60-65‹ C. before thu next layer is added. The second layer is allowed to reach a temperature of 50-55‹ C. before the third layer is added, and each succeeding layer is allowed to reach the same temperature before the next is added. When the last layer has been added and has reached a temperature of 50-55‹ C., the pressure cover is applied with a pressure of 400-500 kilograms per square metre. Each layer is made convex at the centre so that, when the pressure is applied, it acts first in the centre of the container and then gradually outwards towards the sides. The pressure is such that it controls the temperature and degree of fermentation. If the fodder is so wet that it will not reach by fermentation a temperature of 50-55‹ C., the cover is applied for a short time with a pressure of 50-100 kilograms per square metre to encourage fermentation and raise the temperature to the required extent. To prevent mould forming, the press cover is raised after about 12 hours for a pexiod of about 6 hours to allow of the evaporation of the moisture given off by the process of fermentation.
