Title: Water soluble cationic thermosetting resin
Inventor: BABCOCK DOUGLAS CRAIG
IPC: C08G69/48
Filed: 1965-12-20
Abstract: An aqueous solution of a cationic thermosetting resin having a pH of 3.4 to 3.6 is obtained by reacting equimolar proportions of diethylene triamine and adipic acid to form (a) a water-soluble polyamide which is then reacted in aqueous solution with (b) epichlorohydrin and (c) ammonium hydroxide in a molar ratio (a): (b): (c) of 1: 0.5: 2.5.  In the example the course of reaction is controlled by measuring the rate of viscosity increase which is reduced by lowering the temperature or increased by adding NaOH. When the Gardner-Holdt viscosity is between BBC and BC formic acid is added and the mixture rapidly cooled.  It the pH is not as specified it is adjusted with formic acid.  The solution may be used to impart wet-strength to paper.ALSO:An aqueous solution of a cationic thermosetting resin having a pH of 3.4 to 3.6 and obtained by reacting in aqueous solution in the molar ratio 1:0.5:2.5 (a) a water-soluble polyamide prepared from equimolar amounts of diethylene triamine and adipic acid, (b) epichlorohydrin and (c) ammonium hydroxide (see Division C3) is used under acid or alkaline conditions in the production of wet-strengthened paper.

Abstract: 1332955 Stopping machines at predetermined positions; change-speed gear FUJI DENKI SEIZO KK 3 Dec 1971 [11 Dec 1970] 56315/71 Headings F2L F2E and F2D  A device for stopping a member such as a sewing machine needle in predetermined positions comprises a driving shaft 11 which drives a driving clutch member 12 which in turn can drive a driven plate 13 on an output shaft 14. An intermediate disc 15 rotatably mounted on the output shaft 14 is driven by differential gearing comprising a worm 21 on the shaft 11, pinions 22a and 22b rotated by the worm and journalled in bearings 25a and 25b on a support 13a attached to the driven plate 13, and driving, via worms 23a, 23b, planet pinions 26a, 26b (Fig. 2), which drive a sun gear 27 attached to the intermediate disc. Braking members 33a, 33b, to brake the driven plate 13 and intermediate disc 15, respectively, and actuated by an electromagnet 37 and a spring 34 are also provided, as is an indicator 40 for the direction of rotation of the intermediate disc. An alternative form of brake shoe, operated by an eccentric pin on a shaft, is also described (Fig. 6 (a)). Operation.-With the clutch engaged there is no relative movement between worm 21 and pinions 22a and 22b, the intermediate disc 15 thus rotates at the speed of plate 13. On disengagement of the clutch the plate 13 contacts brake 33a (disengagement being by release of a foot pedal in the case of a sewing machine) which slows this plate and causes relative movement between worm 21 and the pinions, which in turn causes a proportionally greater reduction in speed of disc 15 which eventually stops and reverses direction. This reversal of direction causes a sensor 40 to close a microswitch 43 (Fig. 7) which operates electromagnet 37 (by means of a solenoid 54a operated switch 54b) to be actuated and reverse the brakes 33a and 33b. This results in a slow rotation of plate 13 through the gearing with disc 15 held stopped. On attaining the predetermined position (cam 55c opening contact 55b in Fig. 7) the magnet is again switched off, and brake shoe 33a halts plate 13. In the circuit shown in Fig. 7 switching a contact 52 from 52b to 52a causes the brake shoes to change around again and stops the plate 13 when cam 55c opens contact 55a. The switch 53 is closed when the main control (e.g. a foot pedal) is operated (release of the pedal). The two positions of the cam may correspond to needle-up and needle-down of the sewing- machine.  Brakes.-The brake shown in Fig. 6(a) comprises a member 131 movable radially by an eccentric pin 132 on a shaft 133 to engage the inner conical surface on a member 13 or the outer surface of a member 15. The brake in Fig. 2 comprises shoes 33a, 33b selectively movable to brake discs 13 or 15 respectively.

Abstract: 567,331. Feeding webs. PITNEYBOWES POSTAGE METER CO. Aug. 6, 1943, No. 12724. Convention date, Aug. 22, 1942. [Class 100 (i)] A web feeding device for a printing and cutting machine, first feeds a web from a non- printing position to a printing position between. printing and impression cylinders 10, 11, is then inoperative to allow the web to be printed and fed by a printing segment 41, is again operative to feed the printed section to the cutting device 42 and then retracts the web continuously till its leading end is again in the original position. The feeding device comprises two feed segment members 22, 23, Fig. 1, each comprising a pair of similar segments 22, 22a, Fig. 3, and 23, 23a. The segments 22, 22a are rigidly connected together by studs 28, 28 and are fixed to a sleeve 24 free upon a shaft 25. The segments 23, 23a are also rigidly connected by studs 29 and are secured to sleeves 26, 27 fixed to rotate with the shaft 25. A coiled spring 36 has its ends connected to a pair of the studs 28, 29 so as normally to space the segments apart to leave a gap 37 determined by the engagement of an edge of a flange member 35 on the sleeve 26 with an eccentric disc 31 adjustably mounted on one of the studs 28. A gear-wheel 39 fixed to the shaft 25 engages a segment gear 16 on a lever 14 pivoted on a shaft 15 and having a roller 17 engaging a cam 18 on the shaft 12 of the printing cylinder. The initial position of the parts is as shown in Fig. 1, the leading end of the web being retracted from the bite of the cylinders 10, 11. As the cylinder 10 is rotated, the cam 18 operates through the parts 14, 16, 39 to turn the segments 23, 23a clockwise to feed the web into the bite of the cylinders 10, 11. The gap 37 then remains opposed to the web, to allow the web to be printed and fed by the segment 41. The cam 18 then again operates so that the segments 22, 22a feed the web to a position in which the printed section is severed by the device 42. The cam 18 then reverses the movement of the gear 39 and the segments 23, 23a first turn alone until the opposite edge of the flange 35 engages an eccentric 32 on the stud 28 opposite to the eccentric 31, which movement closes the gap 37, after which the segments move together, retracting the web continuously until its end is in the initial position. After the segments 22, 22a leave the web, the spring 36 again spreads the segments apart.
