Title: Process for dyeing and printing shaped structures of polyacrylonitrile
IPC: C09B7/10
Filed: 1961-08-30
Abstract: Water-soluble dyes of the formula: <FORM:0994482/C4-C5/1> wherein F is the radical of a dye devoid of -SO3H or -COOH group, X is H or hydrocarbon, X is H, alkyl, aryl or aralkyl, are employed in the dyeing or printing of polyacrylonitrile materials.  The hydrocarbons X and R may contain 1-20 C atoms. The tertiary N may be substituted by alkyl, aryl or aralkyl groups or may be a member of an aromatic, hydroaromatic or heterocyclic ring. The dyes may also contain the groups -SO2NH2, -SO2NHCH3, -SO2CH3 and/or -O-(CH2CH2O)n-CH2CH2OH where n is 0-10.  The dyes may be from the azo, anthraquinone, indigo, thioindigo, acridone, phenazine, dioxazine, diphenylmethane, triphenylmethane or phthalocyanine series.  They may be prepared by reacting dyes containing at least one 1 DEG  or 2 DEG  amino group with a halide of the formula <FORM:0994482/C4-C5/2> wherein R is H, alkyl, aryl or aralkyl and treating the reaction product with a tertiary base, e.g. trimethylamine, N-alkylmorpholine, N-alkylpiperidine, quinoline or especially pyridine; the preferred halides are b -chloropropionyl chloride, b -chloro-b -phenylpropionyl chloride and b  - chloro - b  - toluyl - propionyl-chloride. Dyes of the anthraquinone monoazo and thioindigo series are prepared in the examples.ALSO:Shaped structures consisting wholly or substantially of polyacrylonitrile are dyed or printed by applying preferably from an aqueous medium, at a pH value below 7 a water-soluble dye of the formula:  <FORM:0994482/D1-D2/1> wherein F is the radical of a dye devoid of -SO3H or -COOH groups, X is H or a hydrocarbon and R is H, alkyl, aryl or aralkyl.  The hydrocarbons X and R may contain 1-20 C atoms.  The tertiary N may be substituted by alkyl, aryl or aralkyl groups or may be a member of an aromatic, hydroaromatic or heterocyclic ring.  The dyes may also contain, to improve their water-solubility, the groups -SO2NH2, -SO2NHCH3, -SO2CH3 and/or -O- (CH2CH2O)n-CH2CH2OH where n is 0-10.  The dyes may be derived from the azo, anthraquinone, indigo, thioindigo, acridone, phenazine, dioxazine, diphenyl-methane, triphenylmethane or phthalocyanine series. Dyeing may be carried out at 90-130 DEG C. and prints may be steamed at 100-145 DEG C.  Dispensing agents, e.g. an alkylphenol-ethylene oxide adduct and retarding agents, e.g. the reaction products of dodecyl chloride or benzoyl chloride with pyridine or polydimethylaminoacrylates quarternised with dimethyl sulphate, may be coemployed.  Examples are given.

Title: Improvements in or relating to belt conveyors
IPC: B65G45/00
Filed: 1935-11-12
Abstract: 461,926. Endless - belt conveyers. MAVOR & COULSON, Ltd., and THOMSON, J. Nov. 12, 1935, No. 31280. [Class 78 (i)] In belt conveyers provided with an elevator at one end to raise spillage that has fallen on the return run back on to the top conveying run, the elevator containers are so mounted as to discharge their contents in their wake as they travel over the top run. Fig. 4 shows an elevator comprising endless parallel chains 3 embracing the upper run 1 of the conveyer. Buckets 4 are pivoted at 12 to the chains 3, and have at each end rollers 13, 14, one on each side of the pivots 12. The rollers 13, 14 coact with stationary guides 15 which are so shaped as to allow the full rising bucket in the position 16 to hang vertically, and by a bend 17 to tip it while over the run 1 so that it proceeds bottom first and ejects its contents in its wake. A bend 18 strikes the rollers 14 to reverse the aspect of the bucket and allow it to scrape up the material from the bottom run 2 in its traverse thereacross. Fig. 8 shows a modified form in which the chains 3 embrace both runs 1 and 2, a scraper 23 pushing the material off the bottom run 2 into the path of the buckets 4. The elevator is driven from the conveyer by bevel reduction gear and chain, by a rope system, by spur wheels, &o., and may be safeguarded against damage, when the conveyer is reversed, by a one-way clutch. Specifications 298,788, [Class 78 (i)], and 428,056 are referred to.
Patent GB-386388-A (GB)
Title: Improvements in conveyor systems and means for driving the same
IPC: B65G23/00
Filed: 1931-11-11
Abstract: 386,388. Endless-chain conveyers. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Webb, J. B. ; 1624, Woodsboro Drive, Royal Oak, Michigan, U.S.A.) Nov. 11, 1931, No. 31282. [Class 78 (i).] A long conveyer is driven by a number of driving units situated at intervals along its length, some of said units including compensating means responsive to an increase in the load placed upon it beyond a predetermined amount to check its driving effect. The chain 11, Fig. 10, has a master driving unit M, and auxiliary driving units A1, A2, A3, each of which includes an endless driving chain 12. The units A1, A2, A3 are provided with the compensating device, and in them the driving mechanism is carried by a movable frame 17 which is slidably mounted in a fixed frame 15 and normally is urged towards one end of this frame by springs 42. The driving sprocket 14 is fixed to a gear 32, Fig. 2, rotatably mounted on a shaft 33 secured in the frame 17. The gear 32 engages a gear 31 on a shaft 30 which is connected by bevel gears 29, 28 to the shaft 26 of reducing gear 25 mounted on a base 23 in the frame. The other shaft of the gear 25 is connected by a flexible coupling 50 to the shaft 51 of a variable-speed driving device which consists of two pairs of opposed cone pulleys 52, 53, and a connecting belt 54, Fig. 1, provided with means whereby one member of each pair may be shifted axially relatively to its co-operating member. The movable pulley of each pair is secured to a lever 55 which is pivoted at 56 in the supporting frame 57, and carries a nut 58 in engagement with a threaded shaft 59. This shaft is connected by bevel gears to a shaft 64 provided with a hand-wheel 69 and carrying a pinion 65 which can be engaged at will with a rack 66 fixed to the frame 15. The input shaft 73 of the variable-speed gear is driven through chain. and-sprocket gearing by a motor 75. The pinion 65 is moved out of engagement with the rack 66, and the hand-wheel 69 is turned to produce the desired adjustment. The pinion 65 is then engaged again with the rack. If too heavy a load is placed on one of the units, its frame 17 will yield against the action of the springs 42, and the frame will move to the left, Fig. 1. This movement will cause the pinion 65 to roll on the rack 66, and the consequent rotation of the shaft 64 will cause an adjustment of the variable-speed gear to reduce the speed of the chain 12. In a modification the movement of the frame 17 is used to actuate a limit switch controlling the motor 75.

[Also in Group XXXIV] A machine-tool having two members displaceable relatively to one another, such as a table along a bed, has rotatable shafts interposed between the members, the axes of the shafts extending parallel to the direction of travel of the displaceable member, the load being transferred between the members by lubricant films created between the shafts and bearings rigidly secured to the respective members, each bearing embracing substantially one half of a shaft and the bearings being arranged in succession in a row with the distance between the exterior edges of the outermost bearings greater in the stationary member than in the displaceable member. The bed 10, Fig. 2, carries a longitudinally-movable table 12. The top surface of the bed is formed with upwardlyprojecting walls 14 which provide channels for a number of half-bearing blocks 16. The latter carry two shafts 18 which are driven by pulleys 20, Fig. 1, and belts 66 from a driving- shaft 62. The table is provided with two inverted U-shaped members 22 rigidly secured thereto, which fit over the walls 14 and have a number of upper half-bearing blocks 26 secured to the bottom of the U. A cover 34, secured to the bed by uprights 30 passes through the clearance provided between the parts 22 and the table 12 to protect the shafts 18 from cuttings; bellows-type covers 35 arealso provided for this purpose. The longitudinallyextending trough formed by the walls 14 and the end-pieces 30 is partly filled with oil. The table 12, Fig. 2, may be locked to the bed by a hand wheel 88 mounted in the bed which closes a pair of jaws 94, 96 on to a plate 98 secured to the table. The plate is rigid in the longitudinal direction but transversely flexible, which prevents the setting up of transverse forces in the guideways. An experimental arrangement is provided with spring-means 72 which may be adjusted to simulate different loading conditions on the table. A bar 70 connects the spring-means to a bearing-lever 68 which slides along a shaft 56 mounted in the bed and rotated by the shaft 62 for rotating the guideshafts 18.

Abstract: 340,655. Building, vehicle, and ship constructional elements. SOURDIS, P., 3, Place de la Madeleine, Paris. Oct. 16, 1929, No. 31459. Convention date, Nov. 13, 1928. [Classes 20 (ii), 20 (iv), and 87 (i).] Slabs and like elements for building and other purposes, of the kind in which the embossed portions of a metal plate are soldered or riveted to a second embossed or plain metal plate to form a partially hollow slab, are constructed with the lateral walls of the embossed portions thinner than the plate itself. Fig. 1 shows an example in which the lateral walls of the embossed portion a of the plate A are thinner at all points than the unembossed parts of the plate but increase in thickness towards the greatest depth of the embossed portion. In this instance the plate A is soldered to a flat plate B and the intervening space filled with concrete d reinforced by rods e. The concrete may be replaced by a light alloy or weld. ing material. Two embossed plates may be soldered together instead of an embossed plate and a flat plate. Fig. 2 shows a plate rolled with thicker portions 2 on opposite faces to assist in forming the embossed portions in accordance with the invention. The parts of the plate between the embossed portions may be corrugated or undulated in one or more directions. The height of the embossed portions may vary so that the two plates will not be parallel when assembled, or the second plate may be curved. The slabs may be adapted to fit in special places by bending the plates between the embossed portions before assembly. Fig. 4 shows the flat plate provided with holes f to allow the plaster of a ceiling to penetrate, thus anchoring it in position. The slabs or panels are stated to be applicable as wall, ceiling, roofing, or flooring elements, frame members for vehicles and ships including submarines, and for aeroplane structures and accessories, and also may be bent into rings for walling in mines, shuttering for reinforced concrete, bridges and radiators.

[Also in Group XXIII] A method of removing material from the surface of a metal workpiece 9 comprises pressing one or more narrow finely toothed annular edges 13 of a high-speed rotary tool 1 against the surface to fuse the material thereof by the frictional heat produced and to remove the fused material. The tool may have a number of edges on a disc 1 mounted on a shaft 2 and supported by rollers 5 against a guide 7. The disc is moved substantially perpendicular to the axis of tool during abrading. In other embodiments, Figs. 2, 3 (not shown), one or four friction edges may be provided or two separate rings 11, Fig. 4 (not shown), each carrying two friction edges, may be secured by screws or rivets in a rotary backing disc. The teeth may extend partly or entirely up the side walls of the annular webs 4 which may be formed obliquely to the axis, Fig. 6 (not shown). In another embodiment, Fig. 5, an abrading ring 11 with two friction edges may be combined with a grinding disc 12; the ring 11 may be adjusted axially, before or during treatment, by an hydraulically operated ring 10a. In another embodiment, Fig. 9, the abrading tool comprises a plurality of parallel discs 4 with spacers 27. The invention may be used with loose abrasive grit preferably carried in a gaseous or liquid medium and delivered through nozzles 20, Fig. 12 (not shown). The gaseous medium may be oxygen which assists in fusing the surface of the workpiece. In one embodiment using an abrasive grit, Fig. 14, the workpiece 9, which may be a rotating shaft, is fed through seals 24 into a closed container 21 containing the abrasive tool 1, and filled with the abrasive grit. A similar arrangement is described for abrading the surface of a rail 9, Fig. 13 (not shown). For protecting the tool from the abrasive grit, it may be enclosed in a coating of elastic material applied by dipping or spraying. The serrated edges of the rotary tool may have recesses 14, 28, Figs. 7, 8 (not shown) in which the loose grit is carried. In another embodiment, Fig. 10, abrasive grit is embedded in a ring 16 of plastic material adapted to be pressed against the workpiece by an hydraulic piston 18. The workpiece and the disc may be connected across an electric supply to produce arcs which assist removal of the surface material.
