Abstract: Polytriazoles, e.g. those prepared according to Specifications 612,609 and 613,020, are heated in an inert organic liquid, heating being discontinued while the polymer is still fusible and soluble. The temperature of heating may be 200 DEG  to 300 DEG  C., e.g. 210 DEG  or 250 DEG  C., and the period may be 10 or 20 hours or more. The organic liquids may be either solvents or nonsolvents for the polymers, e.g. polyhydroxy pylene glycol or glycerol, phenolic compounds such as phenol, cresols or xylenols, or high-boiling hydrocarbon oils such as those boiling at 250-300 DEG  C. or above. The quantity of liquid may be 100 to 200 per cent of the weight of polymer.  The modified polymers, which are of increased intrinsic viscosity, may be used for making films, filaments, and other articles as described in the above-mentioned Specifications.  In examples (1), (2), (3) a polyaminotriazole of intrinsic viscosity 0.32 (prepared by heating sebacic dihydrazide in the presence of hydrazine hydrate) is heated under nitrogen with (1) an equal weight of ethylene glycol for 12 hours at 210 DEG  C. to give a polymer of intrinsic viscosity 0.72 which can be spun from solutions, e.g. in cyanhydrins; (2) twice its weight of "omega oil" (a high-boiling paraffin) for 1 hour at 250 DEG  C. to give a polymer of intrinsic viscosity 0.67 which can be spun from solutions, e.g. in cyanhydrins; (3) with an equal weight of m-cresol for 8 hours at 200 DEG  to 210 DEG  C. to give a polymer of intrinsic viscosity 1.01, soluble in cyanhydrins (e.g. acetaldehyde cyanhydrin) and giving films which can be dyed, e.g. by 1-amino-4-hydroxyanthraquinone; (4) a polyaminotriazole of intrinsic viscosity 0.33 (prepared by heating adipic dihydrazide in the presence of hydrazine hydrate) is heated under nitrogen with an approximately equal weight of m-cresol for 6 hours at 210 DEG  C. to give a polymer of intrinsic viscosity 0.52 which can be spun from solutions, e.g. in cyanhydrins.

Title: Improvements in or relating to apparatus for enumerating and indicating the number of available seats on the decks of passenger carrying vehicles
IPC: G08B5/22
Filed: 1943-03-10
Abstract: 573,986. Indicating available seats on vehicles. COLT, G. H., and CHAPPELL, A. J. March 10, 1943, No. 3913. [Class 106 (i)] Apparatus for enumerating and indicating the number of available seats on the decks of passenger vehicles is actuated electrically by the closure of switches associated with three adjacent stair treads, the apparatus including solenoid-operated pawl-and-ratchet mechanism for moving a dial or band in opposite directions and selector mechanisms operated by the ascent or descent of a passenger, the selection of the appropriate pawl being made by the operation of the top or bottom tread and the energization of the solenoid by the middle tread. As shown, the dial D is moved in one direction by a pawl P<1> and in the other by a pawl P<2> operating a wheel W<4> geared to the dial, the pawls being connected to a crosspiece A<1> operated, against a spring S<4>, by a solenoid L<1> through a switch T<4> on the middle tread E<2>. The pawls are moved into and out of operative position by the engagement with pins N<5>, N<7> thereon of inclined members U<2>, Us on a rod V<1> pivoted at N<1> and operated by solenoids L<2>, L<3> respectively. The solenoid L<2> is energized by the depression of the top tread E<3> and its circuit includes a switch T<2> operated by a lever V<3> from a connecting member R<4>. Similarly, the solenoid L<3> is operated by the bottom tread and a switch T<1>, operated by a lever V<2> from a connecting member R<2>, is included in its circuit. Each of the solenoids L<2>, L<3> operates the lever V<1> through a lostmotion device R', R3 and is returned by a spring S<5>, S<6> operating in a dashpot, whereby the energization of the solenoids effects an immediate opening of the switch T' or T<2> in the other circuit, thus preventing the energization of the other solenoid until the switch has been closed, after an interval, by the associated spring and dashpot. The bottom tread E<1> closes the switch T when the tread has made half its movement only, the switch being open when the tread is fully depressed and during its return. This provision enables a passenger to stand on the bottom tread before dismounting. In other forms, the rod rocks transversely of the pawls, or the pawls engage with oppositely-disposed ratchets on the dial wheel. Specification 505,008 is referred to.

Title: Improvements in meat clamps for slicing machines
IPC: B26D7/02
Filed: 1928-02-08
Abstract: 311,669. Nightingale, T., and Booth, J. Feb. 8, 1928. Cutting slices in succession.-A clamp for slicing-machines includes a sleeve slidable on a post and is characterized in that the sleeve, or ferrules fitted thereon adjacent to the post, is, or are, pressed against the post by the rotation of the food clamping lever about its pivot on the sleeve, by a cam device set in operation by the food clamping bar. As shown in Figs. 1, 11, the clamp bar 5 is forked to embrace the sleeve 2 and is pivoted thereto by a bolt 4 on which ferrules 6, 7, 11 are threaded. The ferrules 6, 7 are shaped to engage the post 3, and the ferrule 6 has a diametral recess 14 engageable, at times, with a diametral projection 13 on the ferrule 11. The ferrule 11 is keyed in the arm 12 of the bar 5 so that when the arm is swung on the pivot bolt 4, the ferrule 11 moves with it. When the arm 5 is raised against the stop 27, the rib 13 fits in the recess 14 and the ferrules 6, 7 are released from the post 3. When the arm is brought down towards the meat, the rib 13 rides out of the recess 14 and causes the ferrules 6, 7 to grip the post thereby locking the sleeve. The upward movement of the bar 5, due to the pressure of the meat, is resisted by an arm 15 pivoted to the bar at 20 engaging the curved face of a quadrant 19 which is attachable to the sleeve. The pivot 20 of the arm 15 is disposed beneath the axis of the lever and the pivot is provided with an eccentric adjusting device. The arm 15 is normally pressed into the operative position by a spring 18, and is disengaged for manipulation of the bar 5 by pressing down the projection 16 at the free end of the bar. In the modification shown in Fig. 4, the ferrules 6, 7 are dispensed. with, the sleeve itself being split to grip the post when the projection 13 on the ferrule rides out of a diametral recess on the face of the sleeve. Adjustment of the sleeve-clamping means is effected by lock nuts 9 and spring washers 10. In the modification shown in Fig. 7, two posts 3 are provided, the ferrules 7, 24, 6 being acted upon by the projection 13 on the ferrule 11 to grip both posts. When two posts 3 are used, one bar 5 may be pivoted to two separate sleeves, or one bar 5 may be pivoted to each sleeve. To prevent rotation of the bar 5 on the post, the post may be flattened at 30 a projection 31 being provided on the sleeve to engage therewith. In further modifications, the spring 18 is replaced by a coil spring threaded on a depending pin on the arm 15, or the quadrant 19 has a toothed face engaged by a spring- pressed pivoted detent which is disengaged, for manipulation of the bar 5, by pressing the end of a rod which projects from the free end of the bar 5.
