Title: Improvements in or relating to agricultural tractors
IPC: A01D78/00
Filed: 1959-05-13
Abstract: 915,869. Haymaking machines. VAN DER LELY N. V., C. May 13, 1959 [June 12, 1958], No. 16449/59. Class 6(3). [Also in Group XXXII]. A tractor-implement coupling, for a tractor 28 having a transverse drawbar 27 at its rear end, comprises a coupling beam 25 to which the implement is coupled, the coupling beam being attached to the drawbar by means which enable it to be turned, relatively to the drawbar, through 180 degrees about a horizontal axis parallel to the longitudinal axis of the tractor, between two positions wherein it extends horizontally, the beam being lockable in the two positions. The beam is fixed to a shaft 41 pivoted in a horizontal bearing 29 carried by the drawbar 27 and adjustably secured thereto by hook-like brackets 30, 31 which are slidable therealong. The beam 25 carries a stop 46 which engages the drawbar 27 in both positions thus reducing the bending moment on the coupling beam 25. The beam is locked in position by a pin 41A inserted through the bearing 29 and shaft 41.

Title: Improved moisture control in spinning synthetic aromatic polyester filaments
Inventor: COATES RONALD BELL
IPC: D01F6/62
Filed: 1969-03-28
Abstract: 1,237,052. Low moisture spun polyester yarn. IMPERIAL CHEMICAL INDUSTRIES Ltd. 24 Feb., 1970 [28 March, 1969], No. 16457/69. Heading B5B. Filaments of aromatic polyester are made by melt extrusion, metered application of processing aids dissolved or dispersed in water, collection of filaments in a package, and drawing, characterized in that the initial concentration of water in such package is less than the concentration of water within a single such filament in equilibrium with an atmosphere of 100% selective humidity. In addition the initial concentration of water in a package of filaments produced as above may be within plus or minus 25% of the concentration of water in such a filament in equilibrium with the ambient atmosphere. In an example, 30 filaments of polyethylene terephthalate with an intrinsic viscosity of 0À67 measured in orthochlorophenol at 25‹ C. are extruded at 290‹ C. and wound up as 9À5 lb. bobbins of 537 denier zero twist yarn at 3226 feet per minute. The ambient atmosphere fluctuated between 50% and 65% relative humidity. A spin finish consisting of (A) 70% of the stearic acid ester of a hexadecyl alcohol; (B) 15% of the reaction product of 1 mole of cetyl/oleyl alcohol and 2À5 moles of ethylene oxide, and 12À5% of the reaction product of 1 mole cetyl/stearyl alcohol and 17 moles of ethylene oxide; (C) 2% dicresylol propane; and 0À5% stearic acid is applied to the filaments after extrusion and before wind up as a 14% by weight dispersion in water at a rate such that 0À4% by weight of total active finish ingredients are applied to the filaments. The theoretical application of water was therefore 2À46%, but due to rapid evaporation from the high speed threadline before winding, the moisture content of a freshly collected bobbin was 0À35% which would be in equilibrium with an atmospheric humidity of 30%. The spun yarn is drawn by leading it at a tension of 50 grams to a heated feed roll, passing it four times round this roll and a closely spaced skew idler roll and thence to a cold draw roll rotated at a surface speed 3À6 times that of the feed roll. From the draw roll the filaments are collected as a 150 denier yarn. The feed roll temperature is adjusted to an optimum value of 95‹ C. at which the draw tension variability is only 12 grams.

Polymers having repeating units of the formula in which R<SP>1</SP> and R<SP>2</SP> represent any two substituents or together with the nitrogen form a heterocyclic ring, or a quaternary salt thereof, are formed by reacting a polyvinyl alcohol with a compound of the formula ROCH 2 NR<SP>1</SP>R<SP>2</SP> in which R is alkyl and quaternizing if desired. The polyvinyl alcohol may contain comonomers, particularly vinyl acetate and the acetate groups may be removed after the reaction. Exemplified reactants are the N-ethoxymethyl derivatives of N-methyl aniline, morpholine, piperidine, diethylamine, dibutylamine, 4,4-dimethylpiperazine, and N-methyl cyclohexylamine, and quaternizing agents are alkyl p-toluenesulphonates, dialkyl sulphates, alkyl halides, and propane or butane sultone. Reaction with an alcohol reconverts the polymer to polyvinyl alcohol and a solution of the polymer containing an alcohol can be spun into fibres or cast as a film. The quaternary salts can be used as mordants, peptizers, sensitizers or anti-static agents.

Title: Halohydrin containing compounds and the preparation thereof
IPC: C08G59/28
Filed: 1964-04-22
Abstract: 12 gms. of phenylisocyanate was mixed with 41.5 gms. of isopropylidene bis[1-(p-phenyleneoxy)-3-chloro-2-propanol], methylene chloride and stannous octoate (catalyst) and allowed to stand for sixteen hours at room temperature. The resulting product was dehydrohalogenated to the epoxyoxazolidinone by adding NaOH in dioxan at 70-75 DEG  C.  The mixture was cooled, neutralized with CO2, filtered and dried, to obtain a viscous yellow syrup.ALSO:Poly - (beta - haloalkylurethano) halohydrin compounds are prepared by reacting an organic polyisocyanate with a poly-(halohydrin) in quantities providing 1.1-4.0 halohydrin groups per -NCO group.  The term "beta-haloalkylurethano" refers to the <FORM:1070582/C3/1> radical where X is a halogen, the term "poly-(beta - haloalkylurethano) halohydrin" means compounds containing two or more halohydrin groups <FORM:1070582/C3/2> where X is a halogen and two or more beta-haloalkylurethano radicals.  The isocyanate may be a compound containing two or more -NCO or -NCS radicals.  The poly-(halohydrin) may be of formula <FORM:1070582/C3/3> where m is an integer between 2 and 5, X is a halogen and Z1 is a polyvalent organic radical or a covalent bond directly connecting two halohydrin moieties.  The polyisocyanate is preferably tolylene diisocyanate and the poly-(halohydrin) is poly-(epichlorhydrin) or isopropylidene bis - [1 - (p - phenyleneoxy) - 3 - chloro - 2 - propanol]. The polyisocyanate may be the reaction product of tolylene diisocyanate and polypropylene glycol and the poly-(halohydrin), the adduct of epichlorohydrin with polyethylene glycol or trimethylolpropane. In a typical Example (6) an adduct of tolylene diisocyanate and polypropylene glycol was reacted with an adduct of epichlorhydrin and polypropylene glycol.  The product was dehydrohalogenated with sodium hydroxide to yield an epoxyoxazolidinone which was dissolved in acetone and used as a plasticizer for a 1/1 ethyl acrylate/methyl methacrylate polymer dissolved in toluene. Epoxy oxazolidinones may also be used as plasticizers for polyvinyl chloride.  In Example (3) an epoxy resin was prepared by dihydrohalogenating the reaction product of tolylene diisocyanate (17 gms.) and isopropylidene bis - [1 - (p - phenyleneoxy) - 3 - chloro - 2 - propanol] (85 gms.) with aqueous NaOH.  The polyepoxides obtained by dehydrohalogenation of the halohydrins with alkali are cured with conventional curing agents for epoxy resins.

Title: Improvements in or relating to methods and apparatus for baking coating upon cores
IPC: H01B13/06
Filed: 1930-05-30
Abstract: In apparatus for baking a coating of enamel or the like on a core such as wire, by heat generated by combustion of the solvents of the coating material, deposition of soot on the core is prevented by introducing air into the combustion chamber in such a manner that the flame and products of combustion are deflected away from the core. As shown, the wire 14 is guided by a sheave 13 through a bath 5 containing the coating material and passes upwardly through a tube 25, in which the solvent is vaporized by electric heating elements 47, 48, to the combustion chamber 57 which is fitted with a spark plug for igniting the vaporized solvent.  Air is supplied from side chambers 38, 41, through perforations 55, 56, the latter extending to a greater height than the former so that the flame 70 is deflected away from the wire into the offset portion 57 of the combustion chamber.  The chambers 38, 41 are fitted with gauze diffusers 64, 65, which serve to equalize the pressure of the air which enters through slots 62, 63 from passages 39, 42 communicating with a source of air under pressure.  The lowermost apertures 55, 56 are inclined upwardly to prevent the flame from travelling down the wire to the bath 5. The latter is formed with a pair of arms 12 in which the sheave 13 is journalled and is slidably mounted on a baseplate 4, its position, and consequently that of the sheave 13, being adjusted by a screw 6. Supply and discharge pipes 8, 10 for the coating material are connected to the bath 5 by flexible branches 7, 9, which are fitted with valves 11 by which the material may be maintained at a constant level in the bath.  An exhaust duct 68, disposed adjacent the outlet for the coated wire, is connected to a main exhaust passage 69 which is mounted on the outer heat-insulating casing 66 and provided with an exhausting device. The material supplied to the bath 5 may have the following composition:--158 lbs. low-grade pitchy ozocerite, 16,5 lbs. commercially <PICT:0355821/III/1> pure ozokerite, 11,5 gallons castor oil, 36,5 gallons mineral oil of specific gravity ,86, 19,5 gallons asphaltum, 1 lb. glue, 40 gallons turpentine, and 42 gallons kerosene.

Title: Improvements in and relating to friction clutches
IPC: F16D13/40
Filed: 1940-11-29
Abstract: 561,959. Friction clutches. BOULTON PAUL AIRCRAFT, Ltd., TOMPKINS, W. C., and DOE, A. Nov. 29, 1940, No. 17085. [Class 80 (ii)] [Also in Group XXI] A friction clutch, in which slip is varied automatically, comprises spaced driving discs 16, 17, clamped together by a nut and bolt 26, 25, and rotated in bearings 11, 12. Driven discs 31, 32, between the discs 16, 17, are urged towards one another by springs 38 and are splined to a sleeve 35 journalled on the hubs 20, 21 of the discs 16, 17. Between the discs 31, 32, are plates 47, 48, spaced apart by balls 60 which engage cam grooves 59, or recesses, in the adjacent faces of the plates. Thrust bearings 49 are positioned between the plates 47, 48, and discs 31, 32. The plate 48 is clamped to a fixed framework by a plate 50, and the plate 47 may be angularly moved by a tongue 56 either by hand or automatically. Such angular movement causes separation of the plates 47, 48, due to the camming action of the balls 60, and hence engagement of the clutch discs 31, 32, with the discs' 16, 17. The amount of slip in the clutch varies with the angular movement given to the tongue 56. Drive from the driven plates is taken by a sprocket wheel 43 which is connected at 40 to disc 31. As shown, the clutch is utilized to drive the ammunition belt 1 of a machine gun in accordance with the tension thereof. The framework 5, 6, carries a feed sprocket 3 for the belt 1, is journalled about the axis of the clutch around the bearing 11, and is connected to the tongue 56. The sprocket 43 is connected to a sprocket 44 fixed to the axle 45 of the sprocket 3. A spring 58 urges the framework 5, 6, clockwise, Fig. 1, against a stop 9. In this position the clutch is disengaged. The driving clutch plates 16, 17 are constantly driven by a gear 29 through an easily breakable pin 30. When the gun starts to fire the tension in the belt 1 causes anticlockwise movement of the frame 5, 6, and such movement through the tongue 56 causes clutch engagement and thus driving of the sprocket 3. The amount of slip in the clutch thus varies according to the tension of the belt 1. Specification 486,684, [Group XXI], is referred to. Specification 561,958, [Group XXI], is referred to in the Provisional Specification.
