Title: Method and apparatus for converting continuous filaments into spinnable slivers
IPC: D01G1/10
Filed: 1946-08-08
Abstract: 615,387. Spinning yarns. AMERICAN VISCOSE CORPORATION. Aug. 8, 1946, No. 23496. Convention date, April 6 [Classes 120(ii) and 120(iii)] A band of generally parallelized continuous filaments is converted into a staple fibre sliver by continuously feeding the band, disrupting a portion only of the filaments therein at intervals, twisting the band with the disrupted filaments generally disposed within the undisrupted ones, and then disrupting the previously undisrupted filaments in the twisted bands. As shown, a band 2 of continucus filaments is passed between drums 5 and 6, drum 5 being provided with a slitted resilient covering 8 and helical blades 7 which cut the upper surface of band 2. Liquid is supplied to drum 6 through pipe 54 and passes through the perforated drum surface 52 to wet a felt covering 56. A flexible belt 57 of rubber or stainless steel passes around drum 6 and an idler drum 58 and is provided with slits 60 through which liquid from covering 56 is forced by the cutting pressure to wet and weaken the fibres 2 at intervals. The liquid may consist of water or a solvent for the filamentary material. The partially disrupted band is then twisted at 28 by a rotating twisting head 29 in which the band is passed through two sets of rollers 41, 42, 43, at least two rollers of each set being driven. The speed of the second set of rollers exceeds that of the first set so that the hitherto undisrupted fibres are stretched and broken at the weakened points. The band then proceeds to a flier collecting device 29a. The use of liquid may be dispensed with, drums 6 and 58 then being replaced by a simple cylindrical drum. The cutting arrangements may be replaced by high potential electric spark gaps or abrasive means which cut through a predetermined thickness of the material or entirely through alternate longitudinal strips thereof. The second disrupting action may be carried out by cutting instead of stretch-breaking.

Filed: 1956-08-03
Abstract: The invention comprises synthetic polymers coloured in substance with a dye of formula <FORM:0811524/IV (a)/1> wherein R is an aromatic radical (see Group IV (c)).  Specified polymers are polyacrylonitrile, polyvinyl chloride and acetate, polyvinylidene chloride, polyethylene, polylethylene terephthalate and nylon.  The dyes are incorporated into a solution of the polymer or a hot melt thereof, which may then be extruded, moulded or cast &c. to form red-tinted films, filaments or other objects.  The dyes used in the above process may be admixed with up to 20 per cent of a surface-active agent such as a polyoxyethylated higher fatty acid or alcohol.  The dyes may also be dispersed in organic solvents (e.g. xylene, banana oil, ethyl acetate or butyl acetate) and the mixture used to colour synthetic polymers by immersion, padding, spraying or spreading.ALSO:Monoazo dyes of formula: <FORM:0811524/IV (c)/1> wherein R is an aromatic radical (e.g. phenyl, diphenyl or naphthyl which may be substituted by methyl, ethyl, methoxy, ethoxy, nitro and chloro substituents) are prepared by (a) coupling diazotized 2-amino-3-chloroanthraquinone with an appropriate 2-hydroxy-3-naphthoic acid amide or, preferably, (b) diazotizing a compound of formula: <FORM:0811524/IV (c)/2> coupling the diazo compound with an appropriate 2-hydroxy-3-naphthoic acid amide and then hydrolysing and oxidizing the azo compound with an oxidizing agent in an acidic medium.  Specified values of M in the above formula are hydrogen, sodium, potassium, ammonium, mono- or di-methyl- or -ethyl- or -ethanol-amine, pyridine, or morpholine. Specified oxidizing agents are sodium nitrite, ferric chloride, sodium bichromate, ammonium persulphate and hydrogen peroxide.  The dyes are used to colour synthetic polymers such as polymers of acrylonitrile, vinyl chloride, vinyl acetate, vinylidene chloride or ethylene, polyethylene terephthalate and nylon (see Group IV (a)), nitrocellulose and cellulose ethers or esters, in red shades. Dispersions of the dyes in organic solvents such as xylenes, banana oil, ethyl acetate or butyl acetate may be used to colour synthetic polymers.  In examples: (1) 2 - amino - 3 - chloro - anthraquinone is diazotized and the diazo compound coupled with 2 - hydroxy - 3 - naphthoic acid o - anisidide in the presence of a polyoxyethylated higher fatty acid; (2) the sodium salt of 2-amino - 3 - chloro - leucoanthraquinone - 9 : 10-disulphuric acid ester is diazotized and coupled with 2 - hydroxy - 3 - naphthoic acid o - anisidide in the presence of a polymethylsiloxane anti-forming agent and the monoazo product oxidized by heating in water with the addition of sodium nitrite, 2-ethyl-hexanol and hydrochloric acid.

Title: Agricultural machines
IPC: A01D41/14
Filed: 1974-05-30
Abstract: 1459684 Header control for agricultural machines CLAYSON NV 30 May 1974 [14 June 1973 16 May 1974] 24023/74 Heading AIF A combine harvester header 6 is pivoted between working and transport positions by hydraulic rams 9 (only one shown) under the control of a manually or solenoid operated fluid control valve 30. Fluid discharge from the rams 9 during header descent is halted once a ground sensing feeler 20 contacts the ground. Header descent stops once inertia has been overcome. The header working height is automatically controlled during use by a mechanical or pneumatic weight compensation mechanism that maintains an equilibrium weight distribution between the rams and the ground. Working height control:- The mechanical weight compensation mechanism shown in Figs. 2 and 5 comprises a pair of tension springs 18 (only one shown) each of which is pivoted to a respective lever 17 fast on a rock shaft 16. The rock shaft is fast with levers 15 which are pivoted to a respective one of the rams 9. If high ground is encountered the weight borne by the header is increased with the result that the spring 18 is slackened and the levers 17, 15 are pivoted to cause the rams 9, and hence the header 6 to be raised to re-establish the equilibrium position. The reverse happens when a depression is encountered. The pneumatic weight compensation mechanism shown in Fig. 7 comprises a pressure fluid accumulator 41, valve 42, restriction 43 and one way valve 44. Movement between working and transport positions:- Movement of the valve 30, Fig. 5, to the right allows fluid to discharge from the rams via valve 27, non-return valve 37 (which has been hydraulically opened by the movement of valve 30) and drain 36. Upon contact of one of the feelers 20 with the ground. Valve 27 is shut off by the energisation of coil 26 via closure of contact 24. The minimum working pressure required is maintained by non- return valve 38. Contact switch 28 can be used if the feelers are to be overriden when the header must be lowered further, e.g. for dismantling purposes. To raise the header the valve 30 is moved to the left whereupon fluid flows to the rams via valve 38. In Fig. 7 the valve 45 is operated by a header lowering solenoid 48 and a header raising solenoid 46. Contact of the ground by a feeler 20 opens switch 51 to override header lowering solenoid control switch 50. Switch 47 operates solenoid 48 and switch 49 overrides the feelers when required. In Fig. 8 (not shown) the shut-off valve 27 of Fig. 5 is connected between the negative line of circuitry 25 and the dash line between valves 30, 37. Non-return valve 38 is omitted and the pneumatic weight compensation mechanism is used. The hydro-electric valve 27 can be replaced by a pneumatic electro-magnetic or mechanical control and the sensors 20 which can be spring loaded may be in the form of crop lifters or dividers.

As shown, a pendulum comprises a body 7 and a weight 6 rotatable on the body 7, the body 7 being mounted in gimbals 8 and 9 for universal movement. The gimbals 8, 9 are mounted on a body 13 carrying a card holder 14. The body 7 carries a pen 10 pressed by a spring 17 into engagement with a card on the holder. A stop 18, having a V-shaped opening, receives the weight 6 when the apparatus is not in use; a device 19 retains the pendulum in this position. The base 4 is supported on the floor of the vehicle, the retardation of which is to be tested. Levelling screws 23 are adjusted, such that the pen 10 is vertical. The device 19 is released to permit the pendulum to swing, upon retardation of the vehicle, thus causing the pen 10 to record on a card the degree of deceleration. Uneven braking, causing sideways movement of the vehicle, will be indicated by deviation of the trace from the central line. The pendulum movement is damped by a vane 30 secured to the gimbal 8 so as to pass through a magnetic field between permanent magnets 31.
