Title: Yarn storage feeders
Inventor: LAWSON JOHN B
IPC: D04B15/48
Filed: 1972-04-24
Abstract: 1345648 Knitting-machines LAWSON-HEMPHILL INC 24 April 1972 [29 April 1971 5 April 1972] 18818/72 Heading D1C A yarn storage-feeder comprises a drum and a yarn guide rotatable relative to one another, bars mounted in slots in the drum movable to advance yarn turns, and means for sensing yarn turns on the drum and engaging the drive of the device via a pneumatic control. The drive may be locked-on so that the device feeds yarn positively.  - In the embodiment of Figures 1 and 4 the drum 26 is rotated by a drive belt 90 which can be pressed against the rim 88 by a pulley 108. Yarn is guided by an eye 36 to the drum and entrained thereby with the accumulated turns depress a pivoted finger 114. The pulley is supported by a lever 100 and urged away from the rim by a spring 112. A piston 98 is thereby pressed against the diaphragm 46 of an air chamber 44 supplied by an air-line 60. When the finger 114 is depressed a lever 116 is forced downwards to open a ball valve 64 so venting the air chamber 44 via an axial bore 52. The piston is no longer upheld against the force of spring 112, which swings the pulley 108 away from the rim. Simultaneously brake shoes 106 are placed against the top of the drum. The drive is reengaged when the turns are insufficient to depress the finger. Yarn is normally withdrawn substantially axially via a guide eye 38, against the adjustable resistance of flyer 32. If the device is to function as a positive feed, the drive is lockedon by lever 160 supporting an extension 161 of lever 100. The yarn is withdrawn substantially tangentially via guide eyes 165 and 38. The yarn turns are moved axially down the drum by slats 82 projecting through slots 80 in the drum. They are moved downwards and outwards by eccentrically mounted rise-andfall cams 72, 73.  In the embodiment of Figure 9 yarn turns are wound on a stationary drum 226 by a rotatable arm 370, and moved axially by slots 282. The drum is held stationary relative to a fixed upper support by a toothed disc 365 in engagement toothed wheels 360, 361. The disc is mounted on a rotatable inclined bearing 362 which thereby permits the arm 370 to rotate between the stationary drum and support. Yarn turns are sensed by a finger 314 and a lever 300 bearing pulley 308 is operated via pneumatic control as in the previous embodiment. A finger 234 of a stop motion sensitive to absence of turns is also provided.

Title: Vaporisation of water and light oils from tar
IPC: C10C1/04
Filed: 1955-06-29
Abstract: <PICT:0801014/III/1> Water and light oils are removed from tar by causing the tar to flow over at least two weirs and then to flow, in the form of a film, down the internal surface of one or more vertical tubes, the exterior of the tubes being heated by steam, and introducing a gas into the lower ends of the tubes to carry away the steam and light oil vapours evaporated from the falling liquid film. The heatinsulated, middle chamber 17 of the apparatus shown is supplied through inlet 34 with steam at a pressure of 100 pounds per square inch; and the steam-condensate is discharged via connection 37.  Tar is introduced through pipe 30 and flow-regulator 29 into the annular space 23 between the wall of the top cover 19 and the sleeve 21.  The tar flows over the top of the sleeve into annular space 24, then over the top edge 15 of vessel 11 into the space surrounding the upper ends of tubes 26, and thereafter into tubes.  As the tar flows as a film down the inner walls of the hot tubes, the water and lighter oils are volatilized; and the vapours are carried upwards by coke oven gas, which is introduced into the bottom chamber 14 through inlet 32.  The mixture of gas and vapours leaves the top cover 19 through connection 33, which leads to a byproduct plant. Dehydrated tar collects in bottom chamber 14, and is withdrawn through outlet 31.

Abstract: 1,208,372. Particulate detergents. COLGATEPALMOLIVE CO. 23 April, 1968 [25 April, 1967], No. 19119/68. Heading C5D. A detergent composition consists essentially of a blend of (1) hollow spray-dried detergent beads and (2) detergent particles of substantially uniform pock-marked spongeous structure containing spheroidal voids and formed of irregularly shaped coherent aggregates of amorphous and crystalline material including unorientated crystalline platelets. In a preferred form of the invention, the beads and the spongeous particles consist essentially of 2-65% water-soluble synthetic organic detergent and 10-75% inorganic builder salt and the blend consists of 90-99% beads and 1-10% spongeous particles made in a darker contrasting colour. Specified anionic detergents which may be employed are alkyl (or hydroxyalkyl + alkenyl) sulphonates, alkyl benzene sulphonates, alkyl and ethoxylated alkyl sulphates and sodium soaps of a mixture of tallow and coconut fatty acids. Specified non-ionic detergents (which may be used in addition to or instead of the anionic detergents) are ethylene oxide condensates with polypropylene glycol, and isooctyl phenoxy polyoxyethylene ethanol. Similarly, cationic and/or ampholytic detergents may be employed in.compatible amounts. Alkyl amine oxide detergents such as lauryl or myristyl dimethylamine oxides may also be present. The inorganic builder salt may be a neutral or alkaline sodium salt which forms a stable hydrate at room temperature and especially Form II pentasodium tripolyphosphate (which may be added direct or formed in situ by the action of an aqueous base on the trimetaphosphate). Other specified builder salts are Form I pentasodium tripolyphosphate, tetrasodium pyrophosphate, sodium silicate, trisodium orthophosphate, sodium sulphate, sodium carbonate and sodium bicarbonate. In the preparation of the spongeous particles, a slurry of the ingredients thereof may be foamed by the introduction or generation of a gas or vapour (e.g. nitrogen, oxygen, carbon dioxide or steam) with, if desired, subjection to high shear. Thus, the gas may be generated by the decomposition of hydrogen peroxide or a per-salt such as sodium perborate. Other ingredients which may be present are colouring materials, soilsuspending colloidal materials (e.g. sodium carboxymethyl cellulose, polyvinyl alcohol and acidic vinyl polymers such as hydrolyzed maleic anhydride copolymers or their alkali metal salts), hydrotropes (e.g. sodium toluene or xylene sulphonate), foam boosters (e.g. a mono- or diethanolamide of a long chain fatty acid), melamine, optical brighteners, preservatives, fillers and corrosion inhibitors.

Patent GB-191349-A (GB)
Abstract: 191,349. Haddan, A. J. H., (National Cash Register Co.). Oct. 4, 1921. Cash registers with operating-means and several item-value totalizers; item and operation counters.-The registration of an item on a selected one of a number of totalizers is accompanied bv an actuation of a corresponding item counter 209 selected by the differential positioning of an arm 243 carried by a totalizer-selecting cam 153. The end 244 of this arm is thus brought into juxtaposition to a slotted link 215 guided on a common actuating plate 218 and connected to a link 213 pivoted to the counter-driving pawl. In the operation of the machine, a shaft 242 produces through a cam 240 an upward movement of a link 234 which through a. pin 229 rotates a lever 227 to draw downwardly the plate 218 so that its radial slots 217 cause the toggles formed by the links 215, 213 to straighten. This has no effect on the counters except in the case of the selected one, the toggle of which being blocked in one direction bv the arm 243 straightens outwardly and so drives the counter. When totals are being taken, the shaft 92 is rocked anticlockwise and this, through an arm 231, pin 232, and cam slot 233, moves the link 234 to the left, and by thus disconnecting its pin 229 from lever 227 prevents actuation of the plate 218. In this movement of the arm 231 a pin 245 thereon engages a projection 230 on the lever 227 to hold it stationary in order that the pin 229 may subsequently re-engage with its slots in the lever. Specifications 191,350 and 191,351 are referred to.

Patent GB-381942-A (GB)
Title: Manufacture of new anthraquinone derivatives
IPC: C09B6/00
Filed: 1931-07-06
Abstract: Anthraquinone derivatives are prepared by reacting a 1-acylamino-3-halogenanthraquinone with a compound containing at least one replaceable atom of hydrogen or a metal attached to nitrogen, oxygen or sulphur, the process of Specification 381,920 being excluded.  Reaction takes place with elimination of the 3-halogen atom to give dyestuffs.  The properties of these products may be modified by further treatment with an acid condensing agent. Substances suitable for the initial condensation comprise ammonia, an alcoholate, a phenolate, a xanthate, a mercaptan, a thiophenol, a sulphamide, a primary or secondary amine of the aliphatic or aromatic series, or of a condensed ring system such as an aminoanthraquinone, an aminopyranthrone, an aminoanthanthrone or an aminodibenzanthrone. The condensation is preferably carried out in presence of a diluent, an acid-binding agent and a catalyst. In examples: (1) 1-benzoylamino-3-bromanthraquinone (prepared by benzoylating the 1-amino-3-bromoanthraquinone) is condensed with (i) phenol (dyes greenish-yellow); (ii) p-toluidine (dyes bright red shades); (iii) 1-aminoanthraquinone (dyes brick-red); (iv) 1 : 4-aminomethoxyanthraquinone (dyes bordeaux tints); (v) 1 : 5-monobenzoyldiaminoanthraquinone (dyes brownish-red); on treatment with chlorsulphonic acid an orange dyeing product is obtained; (vi) 1 : 8-monobenzoyldiaminoanthraquinone (dyes brownish-red); (vii) 1 : 5-diaminoanthraquinone (\ba1/2\be mol.) (dyes bordeaux shades); (viii) 1 : 4 - monobenzoyldiaminoanthraquinone and the anthramide treated with chlorsulphonic or sulphuric acid (dyes brown); (ix) p-toluenesulphonamide, hydrolysis by means of concentrated sulphuric acid gives a new compound, apparently 1 - benzoylamino - 3 - aminoanthraquinone, which under more drastic conditions yields 1 : 3-diaminoanthraquinone; (x) thiophenol-o-carboxylic acid; (xi) 4-amino-4<1>-chloro-2 : 1 - anthraquinone - thioxanthone (prepared by reacting 1-chloro-4-aminoanthraquinone with 3-chloro-1-thiophenol - 6 - carboxylic acid and condensing the product with chlorsulphonic acid) (dyes grey); (xii) 5-amino-2 : 1-anthraquinone-benzacridone (prepared by reacting the urethane of 1-chloro-5-aminoanthraquinone with anthranilic acid and saponifying prior to ring-closure with chlorosulphonic acid) (dyes violet-brown); (xiii) monoaminopyranthrone (prepared by reducing the mononitro derivative obtained by the action of concentrated nitric acid in nitrobenzene) (dyes black-olive); (xiv) monaminodibenzanthrone (Specification 1818/05, [Class 2, Acids and salts, Organic &c.], (dyes dark green); (xv) 5 : 5<1>-diamino-1 : 1<1>-anthramidocarbazole (dyes red-brown); (2) 1-benzoylamino-3 - chloranthraquinone is condensed with 1 : 4-aminomethoxyanthraquinone as in (iv) above; (3) 1-acetylamino-3-bromanthraquinone is condensed with 1 : 5-diaminoanthraquinone (\ba1/2\be mol.)

Filed: 1953-07-14
Abstract: 727,217. Electric flaw detectors. REPUBLIC STEEL CORPORATION. July 14, 1953, No. 19480/53. Class 37. [Also in Groups XL (b) and XL (c)] A device for detecting flaws in metallic objects utilizes the change in impedance in a search coil when moved over a crack in the surface of the object, the coil being connected to the tank circuit of an oscillator whose output, after passing through several control and amplification circuits, causes a lamp to light, the sensitivity of the apparatus being adjustable to ignore flaws and other variations below a predetermined minimum. The equipment comprises a hand search unit 10 (Fig. 2) carrying the search coil, connected by flexible cable 11 to a unit 12 containing the oscillator and amplifiers, further flexible leads 14, 19 connecting the equipment to control and indicator circuits 15, and power supply unit 16. The search unit 10 (Fig. 3) comprises a moulded handle 21 with two brass extension strips 22 carrying between their ends a coil assembly 25 consisting of a winding 28 (Fig. 5) wound on a thin iron core 29, attached to a synthetic sapphire shoe 32, and cemented into a moulded cube 26 having two small diametric holes which mate with a pin in each brass strip 22 so that the assembly is capable of rotation. Leads from the coil winding 28 are taken via a flexible cable 37 through the handle 21, which also contains an indicator lamp 39, visible through a window in a cover 42. For use with small round objects 401 (Fig. 8) a U-shaped bracket 402 may be assembled over the search coil assembly 25, and provided with curved spring fingers 403. Circuit connections (Fig. 1).-The search coil 25 is coupled to an oscillator 60, contained in the unit 12, whose output after amplification is fed back through a time delay filter 120 to provide a stabilizing control against slow variations due to, e.g., change of contour or texture in the surface of the test body 50, or drift in the circuit constants, &c. The stabilized output from the oscillator unit, containing pulses produced when the search coil 25 passes over a flaw, is fed via amplifier 140 to a meter 190, which only indicates the general level of oscillation amplitude, and also to the flaw indicating circuits, the sensitivity of the indicating apparatus being adjustable by a potentiometer 235. After passing through biased amplifiers 250, 270 which reject minor pulses and disturbances, the flaw pulses may be recorded on a tape recorder 280, or shown on a cathode-ray oscilloscope, or may be amplified to operate a quick-acting relay 350 which closes an energizing circuit, when a flaw is located, for the lamp 39 in the hand search unit 10, and for the lamp 360 on the main unit 15. The sensitivity of the instrument, as determined by the setting of potentiometer 235, may be checked against an object 50 having a series of flaws of known depth.
