Title: Improvements in or relating to a road or rail vehicle traverser
IPC: B61J1/10
Filed: 1954-03-29
Abstract: 746,553. Road or rail vehicle traversers. VEREINIGTE TANKLAGER UND TRANSPORTMITTEL GES. March 29, 1954 [March 28, 1953], No. 9175/54. Class 104 (2). A rail or road vehicle traverser has two double T- or U-shaped main girders 2 which extend in a transverse direction relative to the traverser's travel and are attached to the wheel frames 17 in an inclined manner so that the lower flanges project more than the upper flanges to form running surfaces for the vehicles. The traverser is mounted on wheels 8 which run over tracks 9 in the same horizontal plane as the vehicle tracks 1 or a roadway. At crossing points between the rails 1 and 9 the rails 9 are joined by fish-plates 11 the upper edges of which form running surfaces for flanges 10 formed on the wheels 8. Approach rails 7 pivotally mounted on the end of the main girders 2 and normally held clear of the tracks 1 by springs, counterweights or the like, have guide flanges on their inside and when depressed bear on shaped surfaces 18 on the inside of the vehicle tracks 1 and form a running surface for the flanges 5 of the vehicle wheels 6. The traverser may be driven by an electric or petrol motor mounted on a platform 12 supported by a wheel 13, through a shaft 14 and a dog clutch 15, 16. The shaft 14 and the dog 15 mounted thereon can be moved axially to allow a vehicle to pass on to the traverser and at the same time to disengage the dog clutch 15, 16 to prevent the traverser being driven. A haulage winch for pulling a vehicle on to the traverser cannot be operated till the clutch is disengaged. The traverser may be moved by a diesel locomotive if a second rail is laid at gauge distance from one of the rails 9.

Title: Improvements in and relating to loose reed motions of looms for weaving
IPC: D03D49/68
Filed: 1922-03-30
Abstract: 178,817. Maschinenfabrik R³ti vorm. C. Honegger. April 22, 1921, [Convention date]. Loose-reed motions.-In a loose-reed loom wherein the reed 21 is adapted to be locked to the lay 4 by a clamping-bar 22 coupled by bolts 23 to a locking-bar 12 reciprocated by the connecting-rod, all the parts required for the operation of the locking-bar are mounted on the lay, and projecting parts on the locking-bar are adapted to be shifted yieldingly beneath the nuts of the bolts to lock the reed, and are withdrawn positively to release it. The operating-devices consist of levers 7, 9 and 11, moving in planes at rightangles to one another; the lever 7 is mounted by a pin 6 upon the lay sword 3 and has a roller 8<1> engaging with the forked end of the horizontal arm 9 of the lever 9, 11, which is pivoted at 10 upon the lay. The arm 11 carries a roller 11<1>, which is disposed between a tappet 13 on the bar 12 and the head 18 of a spring pin 17 carried by a plate 14 upon the bar. The plate is also provided with a semicircular locking-nut 15, which, by passing under a flanged nut 24 upon the transverse bolt 23, serves to lock the reed in position. Should a shuttle 27 get stuck in the warp, it will, as the lay moves forward, press back the reed and the bar 22 with the bolts 23, so that the piece 15 will be unable to pass behind the flanged nut 24 to lock the reed. The bar 12 may be actuated through a tension spring instead of through the compression spring 19. The lever 7 may form an extension of the connecting-rod 2.

Title: Microwave duplexer
Inventor: WHELLENS JAMES MATTHEW JOHN
IPC: H01J17/04
Filed: 1961-03-15
Abstract: 926,343. Directional couplers. ASSOCIATED ELECTRICAL INDUSTRIES. March 14, 1962 [March 15, 1961], No. 9504/61. Class 40 (8). [Also in Group XL (c)] A microwave duplexer includes a pair of 3 db. directional couplers 1, 2, a receiver R and transmitter T being connected to waveguides 3 and 4. respectively, of coupler 1, and an aerial A and non-reflective load 29 being connected to waveguides 5 and 6, respectively, of coupler 2. A further 3 db. directional coupler 7 has one waveguide 10 connected through an E-plane bend 11 to waveguide 9 of coupler 1, and the other waveguide 16 connected through an E-plane bend 17 to waveguide 15 of coupler 2. Similarly, a 3 db. directional coupler 8 is connected through an E-plane bend 14 to coupler 1 and through an E-plane bend 20 to coupler 2. Waveguides 21 and 22 of coupler 7 are coupled to a mounting 23 containing two gas discharge tubes, one in each waveguide, arranged in front of short-circuit reflectors 24, and a similar mounting 27 of coupler 8 carries two gas discharge tubes arranged in front of short-circuit reflectors 28. For low-power energy received by aerial A the gas tubes do not fire and the difference in the lengths of the two transmission paths through couplers 7 and 8, respectively, is such that signals reflected from reflectors 25 lag in phase by 90 degrees at end 12 of coupler 1, the signals appearing at end 9 of coupler 1 after reflection at 24. Since the coupler produces a further lag of 90 degrees in energy passing from one arm to the other the signals combine in phase at the receiver waveguide 3 and are cancelled in the transmitter waveguide 4. Energy from the transmitter T will cause the gas tubes to fire and in this case signals at 18 have a 90 degrees phase lead on signals at 15 and due to the 90 degrees lag produced by the coupler 2 the signals will combine in phase in the aerial waveguide 5.

Title: A measuring or indicating instrument
IPC: G01B11/06
Filed: 1941-07-28
Abstract: 552,287. Photo-electric gauging apparatus. MARTIN, C. S., KILBOURN, S. L., and COOKE, A. E. July 28, 1941, No. 9541. [Class 40 (iii)] An apparatus for gauging the dimensions of objects is provided with an arrangement of optical grids controlled by the gauging device to make corresponding variations in a light beam and with a light-sensitive cell, subjected to the light beam and connected to an electrical indicating instrument. As shown in Fig. 1, the apparatus comprises a base 10 and a contact finger 13 adjustable vertically to gauge an object between the base 10 and the finger 13. This finger is carried by a casing 11 adjustable vertically on a pillar 12 and containing a pair of grids 20, 21, Figs. 2 and 3, between lamps 15 and light-sensitive cells 16. The grids are supported by leaf springs 23, 24, and one of them is controlled by the finger 13, which is slidably mounted in the lower wall of the casing. The grids have a number of frames 20a ... 20f of different mesh associated with a corresponding number of lightsensitive cells 16 to give different sensitiveness of response. The cell giving the desired response is connected by a rotary switch 251 to the electrical measuring instrument, the dial of which is shown at 14. Limited stops and means for adjustment are provided. The gauging apparatus may be a spherometer. A single light-sensitive cell may be used and moved from one frame of the grid to another according to the sensitiveness desired. The Provisional Specification mentions also the use of coloured lamps giving indications of correct size, over size, and under size in place of the dial 14.

Title: Improvements in conveyor mechanisms
IPC: B65G47/31
Filed: 1942-07-09
Abstract: 560,149. Conveyers. CROWN CORK & SEAL CO., Inc. July 9, 1942, No. 9578. Convention date, Sept. 9, 1941. [Class 78 (i)] A conveyer mechanism comprises a variable, rotary conveying element adapted to receive containers or other articles of different sizes from a conveyer, and means for driving the conveyer and element at relatively variable speeds. As shown, bottles are transferred from a washing machine 10 by a conveyer 12 to a conveyer 11 from which they are diverted by a transfer device 13 to a conveyer 14 and passed by a pocketed infeed dial 16 through a syruping mechanism 18, in the case of a softdrink filler, and transfer dial 17a to the rotary table 17 of a filling machine. An outfeed dial 17b subsequently removes the bottles to a rotary crowner or capper dial 19 from which they are transferred by a dial 20 back to the conveyer 14, which passes them to a conveyer 22 for transfer to a further point on the bottling plant. At the point of transfer from conveyer 14 to dial 16, it is desirable that larger bottles or containers should be moving at a greater speed than smaller ones, and to effect this the conveyer 14 is driven through a manuallycontrolled, variable-speed mechanism 24 interposed in the driving mechanism for the machine or driven from a separate source. The outfeed conveyer 22 may be driven similarly. One or both of the conveyers 11, 22 may be replaced by the conveyer 14. The dial 16 may be replaced by dials of different sizes having pockets of different conformation, or the size of the dial pockets may be reduced by superimposing thereon plates having pockets of smaller sizes, or a dial with mechanicallyadjustable pockets may be used. As shown in Fig. 2, containers a, b, c, d, e are properly aligned on conveyer 14 by guides 30 and are maintained in the pockets of dial 16 by an arcuate guide 31 which may include a jam detector 32 adapted to move outwardly and stop the machine should a container come between it and a tooth of the dial 16. A timing device for delivering containers to the dial 16 from the conveyer 14 in properly spaced relation, may be used in conjunction with the variable speed mechanism.

Title: Process for the extraction of cellulose from lignified fibrous material
IPC: D21C3/26
Filed: 1938-03-29
Abstract: 516,515. Refining cellulosic materials. KERR, W. T. March 29, 1938, No. 9586. [Class 2 (ii)] Cellulose fibres suitable for producing paper pulp are obtained from lignified material in divided state, by freeing the material from dust and other adherent matter, subjecting it to the action of a weak solution of an alkali hydroxide or carbonate at a temperature not above its boiling point at atmospheric pressure, then subjecting it while in movement to the action of a weak neutral or alkaline aqueous solution containing chlorine, the solution being maintained neutral or alkaline throughout the treatment, then subjecting it to a further treatment with a weak solution of an alkali hydroxide or carbonate at a temperature not above its boiling point, and then separating remaining undissolved impurities from the fibres. Sisal waste, jute waste, hemp, linseed flax straw, cotton linters, wood, e.g., black wattle, and eucalyptus, may be used as starting material. Wood is preferably used in the state of wood wool. Adherent matter and dust may be removed mechanically or by retting. The material may be packed into a metal cage which is immersed in a tank containing hot dilute alkali. The cage may be moved about in the alkali solution so as to ensure a thorough treatment of the fibrous material. The material is washed and then introduced into a long trough containing a warm neutral or alkaline solution of chlorine. It is continuously moved round the trough by means of a paddle-wheel. The solution is circulated and constantly replenished with fresh chlorine water. The solution is kept neutral or alkaline, e.g., by periodic additions of milk of lime. The solution is preferably maintained at a concentration of 1 per cent. available chlorine. The material is washed and then treated with a hot weak solution of caustic soda to remove lignin chloride and remaining chlorine. It is again washed, preferably with a powerful jet of water. If desired the chemical treatments and intermediate washings may be carried out as a continuous process by passing the material and the treating liquids along zig-zag channels of considerable length. At the end of each treatment the material is passed to a separator from which it is washed into a washing channel. After the final alkali treatment extraneous matter such as epidermal tissue, and thickened ends of leaf, is removed by a refiner screen. A preliminary separation may be effected by floating an oil such as cotton-seed oil on the surface of the treating liquid. The epidermal tissue collects in the oil layer and is removed by skimming. The effluents from the three stages may be mixed together to produce precipitation of dissolved substances and to produce an effluent which may be discharged without further treatment.

Title: Method of simultaneously producing substantially pure magnesium oxide and magnesium metal from crude or calcined ores containing magnesium carbonate
IPC: C01F5/10
Filed: 1978-03-10
Abstract: A process for producing magnesium oxide and magnesium from magnesium carbonate-containing ores, in which the latter are dissolved in hydrochloric acid and two part-streams are formed from the magnesium chloride brine obtained in the process, one part-stream of which is passed into a thermal reactor (13) and is dissociated there into magnesium oxide and hydrogen chloride gas. The other part-stream is evaporated, crystallised and dehydrated, and in a molten-salt electrolyser (33) is then split into magnesium metal and chlorine gas. The chlorine gas is fed to the flame of the thermal reactor (13), and the hydrogen chloride gas produced is used to form the hydrochloric acid employed for dissolving the ore. The process permits the simultaneous production of pure magnesium oxide and magnesium metal in an economical and environmentally safe manner. <IMAGE>

Filed: 1972-03-02
Abstract: 1406252 Non-woven fabric IMPERIAL CHEMICAL INDUSTRIES LTD 2 March 1973 [2 March 1972] 9803/72 Heading D1R [Also in Division B5] An autogenously bonded non-woven fabric which may be converted into a carpet by tufting followed by the application of a latex backing is prepared by depositing in random serpentine fashion on moving belt 20 a blend of continuous homofilaments and bicomponent filaments the latter comprising 20-65% of the total number, the homofilaments and the core of the bicomponent filaments consisting of at least partly orientated polypropylene and the sheath of the bicomponent filaments being a copolyamide and comprising 20 to 70% by volume of the bicomponent fibres, laying an array of parallel warp bicomponent filaments 29 having a copolyamide sheath, there being at least 80 warp bicomponent filaments/metre measured in a crosswise direction, and heating to soften the copolyamide sheaths. Preferably a second layer 30 of a blend of homofilaments and bicomponent filaments is deposited upon warp array 29 before the assembly is heated. The bottom surface of mat 28 and/or the upper surface of mat 30 may contain a larger percentage of bicomponent filaments. In example 1 75 parts by weight polypropylene of melt flow index 6 and 25 parts copolyamide (75% hexamethylene adipamide; 25% #-caprolactam) are fed to eight extruders. Six extruders produce 54 polypropylene homofilaments and 26 polypropylene oore:copolyamide sheath filaments with a core:sheath ratio of 40:60 by volume. Two extruders produce 80 bicomponent filaments with an 80:20 sheath: core volume ratio. The filaments are air quenched, drawn 2.55 times by knurled rolls, electrostatically charged and passed to spray guns 21-24 which traverse belt 20. The extruders producing 100% bicomponent filaments feed the last two of the eight guns so that the top surface'of mat 30 is composed entirely of bicomponent filaments. A transverse 500 cycle I minute reciprocating motion is imposed upon each filament stream as it exits from its gun. Disposed between the first four and the second 4 air guns is beam 25 carrying guide tubes for the 160 warp yarns/metre 29 that are pressed onto mat 28 by roller 18. Each warp yarn comprises 40 bicomponent filaments, each 50:50 by volume core (polyethylene terephthalate):sheath (70% by weight hexamethylene adipamide and 30% #-caprolactam). Alternatively the core may be a polyamide. Perforated steam pipes 32, 34 act to discharge the build-up of static. The web is passed between belts 35, 36 into steam chest 41 for bonding, inflatable air bags 42, 43 serving to keep in the steam and to consolidate the web. An aqueous emulsion of equal parts poly(methylhydrogensiloxane) and poly(dimethylsiloxane) is sprayed onto the web at 44 to provide lubrication for the tufting needles and to limit the penetration of the latex backing. The selvedge may be stitched or adhesively bonded. The grab strength, wing tear strength and selvedge strength are specified.

Title: Improvements in or relating to the preparation of cyclooctatetraene
Inventor: HARDY DOUGLAS VERNON NELMAR
IPC: B01J23/78
Filed: 1951-04-27
Abstract: Cyclooctatetraene is prepared by reacting acetylene in an organic solvent, preferably tetrahydrofuran, at 50 - 150 DEG C. in the presence of a derivative of Ni, Co, Cu, Zn or Mn as catalyst, and an addition consisting of the oxide, hydroxide or carbonate of Ca, Ba, Sr, Mg, Zn or Li, e.g. LiOH, CaO, Ca(OH)2, CaCO3, SrO, Ba(OH)2, MgCO3, ZnCO3.  The preferred catalyst is a nickel derivative such as the cyanide, thiocyanate or complexes obtained from b -ketoesters or b -diketones such as ethyl acetoacetate or acetylacetone.  The amount of additives is suitably 0.1 - 5 per cent. on the solvent except for lithium hydroxide where .01-.1 per cent. is preferred.  Generally about .1 per cent. each of additive and catalyst is satisfactory. Batch or continuous operation may be used.  The premixed reaction components may be brought to reaction temperatures or acetylene passed through the other components held at said temperatures.  In Examples, a rocking autoclave is charged with tetrahydrofuran, nickel cyanide, and various additives, acetylene then being charged at 15 atm. and the vessel heated to 65 DEG C.  Several successive rechargings may be effected after intermediate coolings.
