Title: Trailer hitch
IPC: B62D51/02
Filed: 1958-08-14
Abstract: 853,279. Tractor-trailer couplings. YALE & TOWNE MANUFACTURING CO. Aug. 14, 1958 [Dec. 3, 1957], No. 26128/58. Class 103(5). An industrial tractor having a steerable wheel 14. Figs. 1 and 2, is provided with a gripping jaw coupling device comprising jaws 36, 47 which may be closed by a hydraulic piston rod and.cylinder 50, 51 moving systems of parallel links to grip a trailer 54, the arrangement being such that when the jaws are gripping the trailer, further actuation of the rod and cylinder will lift one end of the tractor from the ground to facilitate steering. The parallel linkage system comprises pairs of pivoted links 25, 27; 40, 42 transversely connected at 20, 21, 29 and 30 to a similar set of links on the other side of the tractor, and links 31, 32 common to the sets of parallel links and integral with a transverse bar 34 having a forwardly extending plate 35 mounting the jaw 36. The piston rod and cylinder are connected to one end of a lever 49 integral with an upper sleeve 37 of a pair of sleeves 37, 39 journalled on the pivot rods 29, 30. In operation the studs 55 are preset in their brackets 56. The piston rod 50 is then retracted to cause the linkage 19 to pivot downwardly from the Fig. 1 position, thereby separating the jaw pads 36, 47 until the pads 47 contact the ground. Continued retraction of the piston rod 50 then swings the linkage 17 upwardly, the jaw pads 47 remaining on the ground and being further separated from the pads 36 until the arms 40, 41 contact the bar 34, whereafter both linkages 17, 19 swing. upwardly together. The tractor may then be moved into the Fig. 3 position. The rod 50 is then protracted to swing the linkages downwardly, causing the pad 36 to abut the upper surface of the trailer and hold the linkage 17 from further 'downward movement. Further protraction of the rod 50 raises the pads 47 to clamp beneath the under surface of the trailer so that the end of the trailer is held between the two sets of jaws as in Fig. 5. If now the protraction of the rod 50 is continued, then the cylinder 51 is caused to rise on the now stationary rod 50 to lift the beam 52 and tip the tractor about its wheel 14 until the studs 55 contact the pads 57, Fig. 6. In this position the tractor and trailer are hitched together, and the tractor is steerable about its wheel 14.

Abstract: 482,301. Compound fabrics. BRITISH CELANESE, Ltd. Sept. 28, 1936, No. 26255. Convention date, Sept. 28, 1935. [Class 140] Stiffened fabrics are made by applying heat and pressure to an assembly comprising an outer layer of fabric containing, wholly or in part, filaments or fibres of an organic derivative of cellulose and in contact therewith one fabric consisting wholly of non-thermoplastic textile materials and containing a plasticizer for the organic derivative of cellulose. The heat and pressure is applied in the presence of water, steam or aqueous alcohol, and may be applied locally to form embossed designs and, in this instance, the plasticizer may only be present locally at such points of the backing fabric. The external appearance of the outer fabric is normally unchanged but articles to have a leathery finish may be dipped into an aqueous solution of alcohol, which may contain additional plasticizer, before pressing and in such a case the textile appearance may be wholly obliterated. The pressing may be effected at from 10 to 600 lb. per sq. in. or more and the temperature may be 80 to 180‹ C. or more. Plasticizers specified include para-ethyl-toluene-sulphonamide, dimethyl phthalate, dibutyl tartrate, diethoxy ethyl phthalate, diethylene - glycol - ethylether-ester of phthalic acid, triethoxyethyl phosphate, mixed alkyl and aryl phosphates and camphor, the amount of plasticizer present is preferably 40 to 150 per cent or more of the weight of the organic derivative of cellulose present. The material may be used for collars, cuffs, shirt fronts, hats and sweatbands therefor, cap visors, glove cuffs, cravat linings, garment linings, belts and pocketbooks. The fabrics may be woven, knitted, netted, or knotted.

Couplings, non-automatic.-Railway tracks are - so arranged that the coaches swing in the hori. zontal plane so as to traverse stations with their long sides in the direction of motion and to traverse intermediate parts with their short sides in the direction of motion. The speed of progression changes, being slower at the stations than elsewhere. If the coaches 50, Fig. 1, are connected by bars or links, each coach swings in the same direction, while if the coaches are coupled together, Fig. 2, successive coaches swing in opposite directions, or fold together. In a modification, the coaches are separated but are arranged to swing in accordance with Fig. 1 or Fig. 2, or the coaches may be coupled together to form a complete circuit. Some coaches, Fig. 13, are connected by hinge, joints 65 and others by ball joints 66 and spring couplings 67 for variation in the slope or curve of the line. In Fig. 15, the coaches 60 are connected by bars 61a for the system of Fig. 1 or by other coaches 61 for the system of Fig. 2, or every three coaches 60, 61 may be connected by a link 61a or coach 61<b>. In a mixed system, Fig. 21, the running- gears 92, 93 are placed alternately above and below the coaches, the ball joints 66 and spring connection 67 being also alternate. In Fig. 25 both track rails 90, 98 are on the ground while guiding is effected by rollers and guides above the coaches. In this modification, crossings are necessary in the track rails, but may be obviated by connecting the running wheels to the coaches by outriggers carried at diagonally-opposite corners.

Title: New polymeric composition
IPC: D06P5/22
Filed: 1960-07-29
Abstract: A composition comprises a linear polymer of an alpha-olefin and a linear, regular polymer of a monomer having polar groups containing at least one nitrogen atom.  Specified polymers are homopolymers and copolymers of propylene, styrene, 4-methyl pentene-1, vinyl pyridines, allyl pyridine and butenyl pyridine, with or without acrylonitrile or acrylates.  The nitrogencontaining component may be present in 2%-30% by weight, preferably 2%-10%, based on the composition.  The products have improved affinity for dyes and, in the examples, are spun to fibres at temperatures ranging from 200 DEG -240 DEG C. and pressures ranging from 5-50 kg/cm.2.  Orienting by stretching, e.g. to a draw ratio of 1:1,5 under steam, or to a ratio of 1,77-1,79 at 130 DEG C. and dyeing of the fibres are illustrated. Example 7 also describes the epoxidizing of staple fibres made from a stretched tow by means of boiling aqueous ethylene glycol diglycidyl ether.  Such epoxy compounds have a swelling action on polyvinylpyridine and enhance the resistance of the dyed fibre to solvents and detergents.ALSO:Fibres or yarns spun from compositions of linear polyolefins and linear, regular polymers of monomers having polar groups containing at least one nitrogen atom (e.g. vinyl pyridines), are dyed at 90 DEG -100 DEG C. in the presence of acetic acid and using ACNA Novamina Red 2G (C.I. 14690), ACNA Novamina Yellow C2G (C.I.

Filed: 1971-04-19
Abstract: 1343332 Microporous polyurethanes USM CORP 19 April 1971 [8 April 1970] 26547/71 Heading C3R Microporous polyurethane material comprising a surface zone of fine cells and a zone of cells coarser than the fine cells separated from the surface by the surface zone, the cells being droplet shaped and adjacent cells being connected to each other by openings to provide passageways for air in the material may be prepared by procuring an emulsion of fine droplets of a liquid dispersed as a disperse phase in a continuous phase comprising reactive material comprising as reactive components a polyisocyanate and a compound containing at least two active hydrogen atoms per molecule, casting the emulsion at a casting temperature below the boiling point of the disperse phase liquid on a surface having a temperature below the casting temperature of the emulsion, and allowing or causing the reactive material to react at a temperature below the b.p. of the liquid of the disperse phase whereby the emulsion gels and solidifies with droplets of the liquid of the disperse phase held in the solidified material and after the emulsion has solidified sufficiently not to collapse on removal of the liquid disperse phase, removing the disperse phase to leave micropores in the body, the components of the emulsion and the casting temperature being selected to be such that the emulsion at the casting temperature is unstable whereby the fine droplets of the disperse phase progressively merge together (during the period between casting and thickening of the continuous phase to a point where the droplets are held in place) to form larger droplets in a zone within the emulsion separated from the casting surface by a zone in which the droplets remain relatively fine. Preferred liquids forming the disperse phase are aliphatic hydrocarbons including petroleum hydrocarbon fractions. A surface active agent to aid in dispersing the liquid may also be added, as may solvents for the reactive materials of the continuous phase. A protective cover laid down on the surface of the deposited emulsion layer opposite the casting surface as the layer is formed or promptly after it has been formed gives improved cell uniformity at that surface. The cover may be a release sheet or non-adhesive resin or elastomer sheet.
