Abstract: 1,129,065. Synthetic resins. HERCULES Inc. 16 March, 1967, No. 12472/67. Headings C3B and C3R. [Also in Division D2] An acid stabilized, base reactivatable resin is prepared by first reacting a polyamine, which contains at least 3 amino groups at least one of which is tertiary e.g. methyl bis(3-aminopropyl) amine, with either (A) a C 3 -C 10  saturated aliphatic dicarboxylic acid (e.g. adipic acid or diglycolic acid) in a polyamine: acid molar ratio of 0À8-1À4: 1 to give a polyamide containing free amino groups at least 70% of which are tertiary; or (B) with urea or thiourea in a molar ratio of acid: (thio)urea of 0À7-1À5: 1 to form a poly-ureylene or -thioureylene containing free amino groups at least 70% of which are tertiary. The above polymers from (A) and (B) are reacted with epichlorohydrin in a mole ratio of epichlorohydrin to free amino groups in the polyamide of 0À8-2À0: 1 and in the poly(thio)-ureylene of 1-1À17: 1 to form an aqueous solution of a cationic thermosetting resin containing epoxy groups and chloride ions. The latter resin is then reacted in aqueous solution with from 0À3-1À2 equivalents per equivalent of epichlorohydrin of a water-soluble acid until substantially all the epoxide groups are converted to halohydrin groups. Suitable acids are hydrochloric, hydrobromic, hydrofluoric, hydroiodic, sulphuric, nitric, phosphoric or acetic or mixtures thereof. The resin may be reactivated by reaction with from 0À25-2À5 equivalents per equivalent of water-soluble acid of a base, e.g. NaOH.

[Also in Group XXX] In a method of steering hot rolled material on a delivery roller table, the material is directed into channels formed by flaps, is braked after the run-out period and is thereafter delivered to a cooling bed. Hot rolled material is delivered from the mill to a table comprising rollers 101, Fig. 1, individually movable flaps 1-4 being arranged between the rollers. The flaps define closed channels 1a-4a in which the material is guided. The flaps are individually pivoted about a fulcrum 6 by a lever and draw-rod system, the lower part of a channel first being raised slightly above the level of the rollers to brake the material after run-out and the flap then being further raised to discharge the material across the apron 5c to the moving and stationary racks 105, 106 of a cooling bed. Two delivery tables may be provided to serve one cooling bed. The rollers of the bed or beds may be inclined in either direction to the horizontal. In a further modification, Fig. 8, intermediate plates 30 are introduced to provide two channels on the same flap. Alternatively additional channel bars may be screwed to the tops of the flaps to form a double-channel system, Fig. 14 (not shown). By lowering the flaps so that the channels are wholly below the level of the rollers 101 the hot material may be guided on the delivery table in open channels defined by the backs of the flaps and the rollers, Figs. 12 and 13 (not shown). In another modification the webs of the channels on the flaps are provided with spaced hollows for cooling purposes. In yet another modification the top flange of the channels is inclined so that material from channel 1, Fig. 15 (not shown), is progressively delivered across the racks to the cooling bed.

Filed: 1923-05-16
Abstract: 198,353. Bethlehem Steel Co., (Assignees of Barker, J. S.). May 25, 1922, [Convention date]. Projectile fuzes. - Relates to fuzes having a momentum pellet for delay-action and a directaction striker for instant action adapted to be locked out of action when delay-action is desired. According to the invention, the direct-action striker 17 is so formed as to be rigidly connectible with or disconnectible from the fuze body by direct engagement or disengagement therefrom, without the use of a separate locking or connecting member, for example by means of screwthreads 16, 16<1>, and can be so connected or disconnected to put it out of action or in operative condition by means of a portion 13 thereof extending beyond the fuze. The direct-action striker 17 is normally held forward by a spring 13' which yields to the shock of discharge and allows the rear end of the striker to set back into a recess 39 in a flash passage obturator and detonator carrier 32, but returns the striker forward when acceleration is over. During flight, centrifugal force causes radial bolts 27, 34 to move out against springs 28, 35 and release the momentum pellet 20 and the flash passage obturator 32, and this latter swings about a pivot 33 from the position shown in Fig. 1 to the position shown in Fig. 4, where it is stopped by a stud 42 and locked by a radial bolt 40 moving out into a recess 41. In this position of the obturator 32, a detonator 38 in it is in line with central passages 23, 44, and is ignited by the blow of the striker 17 or the flash from a slow-burning column 25 and transmits the ignition to a "booster" charge 45 in the base of the fuze body. For instantaneous action the parts are initially as shown in Fig. 1. and the fuze is fired by the contact of the projecting part 13 of the direct-action striker with the target. When delay-action is desired, the direct-action striker is screwed up into the fuze body. The striker is then unaffected by acceleration on discharge and is crushed or broken at a weak part 15 on impact but cannot be thrust back against the detonator 38, which, in these circumstances, is fired after a given delay by the flash from the slow-burning powder column 25 ignited by a detonator 24 struck by a firing pin 19 when the momentum pellet 20 shoots forward on impact.
