Patent GB-980160-A (GB)
Title: Improvements in or relating to modifying polymers
IPC: C08C19/22
Filed: 1963-09-06
Abstract: Hydrocarbon polymers are modified by treating them with aliphatic monoazidoformates having the formula <FORM:0980160/C3/1> where R is an aliphatic or substituted aliphatic radical containing from 1 to 3 carbon atoms, to produce polymers of improved dyeability. Azidoformates mentioned are n-propyl azidoformate, isopropyl azidoformate, ethyl azidoformate, monofluoroethyl azidoformate, and methyl azidoformate.  The modification can be carried out by either heating the hydrocarbon polymer in the presence of the azidoformate to a temperature at which the azidoformate decomposes, e.g. from 90 DEG  to 300 DEG  C., or by exposing the polymer in the presence of the azidoformate to irradiation at or below room temperature, the wavelengths used being generally from 1 to 5800 A.  The amount of azidoformate is generally 0.001 to 20% based on the weight of hydrocarbon polymer. The azidoformate may be incorporated with the polymer by milling, or by dissolving it in a solution containing the polymer and evaporating the solvent, or by dipping the polymer in a solution of the azidoformate or by spraying or painting a solution of the azidoformate on the polymer.  The hydrocarbon polymers can be in the form of flakes, fibres or films and polymers mentioned are polyethylene, polypropylene, polystyrene, styrene-butadiene rubber, butyl rubber, natural rubber, polybutadiene, polyisobutylene, ethylene-propylene copolymers, cis-1 - 4 - polyisoprene, ethylene - propylene - dicyclopentadiene terpolymers.  Blends of these polymers with each other or with non-hydrocarbon polymers may be used.  In the examples polyethylene and polypropylene are modified.

Abstract: 1312819 Fishing reels ETABS CARPANA & PONS 22 July 1970 [24 July 1969] 35475/70 Heading A1A [Also in Division F2] A releasable pawl and ratchet device which may be incorporated in a fishing reel comprises pawl 1, coaxially mounted on a shaft 2a of a control button 2 and blade spring 3 which selectively urges the pawl 1 either towards an operative position in which the pawl 1 is in a pawl 1, coaxially mounted on a shaft 2a of a engagement with a ratchet 6a or an inoperative position in which the pawl 1 is spaced from the ratchet 6a. There being sufficient angular play α, between the pawl 1 and the shaft 2a to accommodate angular movement α, of the pawl 1 and the shaft 2a to accommodate angular movement α, of the pawl 1 caused by rotation of the ratchet 6a when the pawl 1 is in its operative position. The blade spring 3 is bowed between a notch 1a in the pawl 1 and a notch 9a in a stud 9 on a housing 5 and in moving the pawl 1 from its inoperative to its operative position the spring 3 passes through an unstable equilibrium position. In its inoperative position (Fig. 7) the pawl 1 abuts against a stop 7 on the housing 5 but counterclockwise rotation of the button 2 causes engagement of surface 2f of the button 2 and surface 1b of the pawl 1 to move the pawl 1 into its operative position (Fig. 1). Counterclockwise rotation of the ratchet 6a is permitted by virtue of the anguar play α, between the button 2 and the pawl 1 (Fig. 9) and clockwise rotation of the ratchet 6a causes movement of the pawl 1 to take up play 11 between the pawl 1 and the button 2 and to cause abutment of the pawl 1 with a face 8a of a projection 8 on the housing 5 (Fig. 10). The ratchet 6a is released by counterclockwise rotation of the pawl 1. The direction of rotation of the ratchet 6a when the pawl 1 is operating may be reversed, an alternative stop 7a and a stud 10 being provided on opposite sides of the button 2 to the stop 7 and the stud 9. An elastic washer 4 takes up play in the mounting of button 2 and the pawl 1 is held on button 2 by a washer 6 removably fixed to the ratchet 6a.
