Title: Improved nylon compositions
IPC: C08K5/53
Filed: 1947-12-30
Abstract: Nylon compositions with improved resistance to discolouration and loss of strength on heating are obtained by incorporating therein a minor amount of hypophosphorous acid or salt thereof, or of an aryl or alkyl phosphinic or phosphonous acid or a salt or ester thereof. Phosphorus compounds specified are hypophosphorous acid; sodium, potassium, calcium, magnesium, barium or ammonium hypophosphite; phenyl phosphinic acid; p-tolylphosphinic acid; hexylphosphinic acid; sodium, potassium or magnesium phenyl phosphinate; the diphenyl ester of benzenephosphonous acid; butyl phenyl phosphinate and ethyl hexylphosphinate.  Preferably nylon fabric or yarn or film is impregnated with a solution of the phosphorus compound, e.g. in water or a lower alcohol, excess solution is removed and the product dried. The added material may be .01-20 per cent of the nylon.  If desired the stabilizing agent may be added to a solution of the nylon in phenol, formic acid or calcium chloride-alcohol mixture, or to the molten nylon.  A number of examples are given employing polyhexamethyleneadipamide; polyhexamethylenesebacamide and the polymer prepared from di-(p-aminocyclohexyl)-methane and sebacic acid.  Other nylons including some interpolyamides and some N-alkoxymethyl polyamides are mentioned.  Usual nylon modifying agents may also be included in the compositions such as plasticizers or delustrants, e.g. TiO2 or a heat-setting assistant, e.g. ethylene glycol. Specifications 461,236, 461,237 and 573,482 and U.S.A. Specifications 2,071,250 and 2,130,948 are referred to.

Patent GB-635067-A (GB)
Title: Improvements in or relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1946-11-28
Abstract: 635,067. Road-traffic signals on vehicles. O'SHEI, W. E. Nov. 28, 1946, No. 35288/46, 36927/46, 483/47 and 16296/47. [Class 118 (ii)] A semaphore-type vehicle direction indicator comprises a flexible coupling between the indicator arm and its actuating means which while normally locking the arm when in its non-displayed position allows the arm to be manually raised. In the non-displayed position, a spring-pressed member carried by the semaphore arm engages with a surface of the actuating member which is parallel to the direction of motion of the latter. At the top of the indicating arm 3 a lever 11 is pivoted at 12 and carries at its other end a roller 15. This lever 11 normally lies along the top edge of the arm 3, being retained in that position by a spring 13. When the solenoid 1 is energized the armature 2 and extension plate 9 descend, stretching a helical spring 16 mounted between the extension plate 9 and roller 15. As soon as a horizontal slot 10 in the extension plate 9 is opposite the roller 15 the latter is carried downwards, rotating the indicator arm 3 about, its pivot 6, and itself moving along the horizontal slot 10. When the solenoid is deenergized the arm 3 falls by gravity, the roller 15 moving back along the horizontal slot 10 and raising the armature 2 until the vertical slot 19 is reached when the helical spring 16 gives the armature 2 a final upward lift and seats the roller 15 in the vertical slot 19, thus locking the arm 3 in the closed position. If the indicator arm 3 is manually raised, the roller 15 rides up the inclined face of the vertical slot 19, the spring 13 slightly lowering the armature 2. Further raising of the arm 3 continues to lower the armature 2. A rigid stop 18 limits the downward movement of the arm 3, when it falls under gravity, the momentum of the arm being absorbed by the flexibility thereof. The lower end of the arm 3 may be located between guide members 20 which should, however, not act as stops, and a guidemember 21 is provided to centralise the armature 2. If the arm 3 is raised manually but the armature sticks, a projection 24 on the bearing plate 5 exerts a direct downward force on the armature until it is depressed sufficiently for the spring 13 to become effective. A fluid operating system may be employed, the solenoid 1 being replaced by a piston and cylinder. In a modification, Figs. 5 ... 8 (not shown), the lever 11 is omitted, the roller 15 being mounted on a pin sliding in an arcuate slot. Specification 362,024 is referred to.
