Title: Improvements in or relating to synthetic ether-resin copolymers
IPC: C08G59/16
Filed: 1953-02-06
Abstract: Esters with drying properties are formed by esterifying an ether resin with an unsaturated acid which has been copolymerized with a vinyl monomer before or during the esterification. Ether resins are formed from polyhydric compounds many of which are listed in the Specification, and epi- or di-halohydrins, or polyepoxides, e.g. bis-(2,3-epoxypropyl)ether or butylene di-oxide.  Monofunctional chain-terminating agents may be included in the reaction mixture if desired.  Many vinyl monomers and many unsaturated acids are mentioned in the Specification.  They may be copolymerized with the aid of benzoyl peroxide, di-tert.-butyl peroxide, sulphur, sulphur dioxide or a redox catalyst, e.g. a mixture of dodecyl mercaptan and benzoyl peroxide.  Other catalysts are also mentioned.  Solvents may be employed, e.g. xylol.  Examples describe the production of copolymers as follows: B-1, B-8 and B-9, linseed oil fatty acids-styrene; B-2, dehydrated castor oil fatty acids-styrene; B-3, dehydrated castor oil fatty acids-acrylonitrile; B-4 to B-7, soybean fatty acids-styrene; B-10, B-11, linseed oil acids-vinyl toluene; B-12 to B-14, soya bean fatty acids-vinyl toluene; B-15 to B-17, Isoline fatty acids (from dehydrated castor oil)-styrene; B-18, Isoline acids-vinyl toluene; B-19 tung oil acids-vinyl toluene; B-20, soya bean acids-isobutylene; B-21, soya bean acids-p-methoxy styrene. A number of examples then describe the esterification of these copolymers with ether resins produced from epichlorhydrin and di-(4-hydroxyphenyl) dimethyl methane. In some examples benzoic acid was also included in the reaction mixture.  The products are soluble in xylol and are film-forming.

Filed: 1969-01-22
Abstract: 1,261,251. Valves. VALVES & PRODUITS INDUSTRIELS SOC. ANON. SCHRADER. 22 Jan., 1969 [22 Jan., 1968], No. 3679/69. Heading F2V. Also in Division G4] In a normally-closed pneumatic relay a closure member 9a is biased by a spring 10a against a seat 11a to block communication between an inlet A and an outlet S. The latter normally communicates with an exhaust P via longitudinal grooves 16a in the stem 5a of the closure member. A piston 6a on the foot of stem 5a forms with the housing a control chamber connected to port B. A pressure signal at B causes the piston to move upwards to open communication between inlet A and outlet S and close communication between outlet S and exhaust P by closure 23a seating on seat 24a. The housing is formed in three parts 1a, 2a, 3a which are held together by a strap 28 in groove 27 and to ensure sealing between the ports, the latter are made of differing hardnesses and have edges 30. The relay may be modified to be normally-open by forming a passage (14) through seat 11a and blocking communication between the outlet and exhaust by a seal (18) placed between the seat and housing part 2a. In modifications of this relay spring 10a may be dispensed with or replaced by an apertured spring membrane (10) and piston 6a may be replaced by a membrane (19) acting on the foot of the valve stem. Instead of the closures being formed as shown by conical surfaces of different inclinations to prevent jamming the closures are formed by rubber seals and are arranged on the top and bottom surfaces of closure 9a. Alternatively the substituted spring membrane (10) may act as the upper closure. Alternative control ports B, C separated by a selector piston (21) may be provided to form an OR gate. In the presence of only one control signal an AND gate may be formed by combining the control and inlet signals. Memories can also be formed by combining relays.

Abstract: 668,680. Seaming non-metallic sheet material. SINGER MANUFACTURING CO. Feb. 17, 1950 [April 6, 1949], No. 4122/50. Class 42 (i). [Also in Group XI] A machine for seaming dielectric sheet material by the application of a radio-frequency field comprises means for feeding the material progressively through the field, a reciprocatory electrode for periodically engaging the material, a stop to limit the material-engaging movement of the electrode, an oscillator, switch contacts for turning the oscillator on and off, a pivoted element carrying one of the contacts, means for actuating the element directly to close and open the contacts periodically, and a lostmotion connection between the electrode and the contact-carrying element whereby the electrode is actuated after the lost-motion has been taken up. As shown, a. roller 31 on the electrode bar 23 presses downwardly, on to the lower arm of a fork 17 which is pivoted at 19 and is spring-pressed on to the lift eccentric 16. Fork 17 carries the adjustable upper contact 51 of an oscillator switch, the lower contact 35 being carried by an extension bar 40 fixed to presser bar 36. Downward movement of electrode bar 23 is limited by engagement of a stop pin 33 with the upper surface 71 of bar 40. Switch contact 51 is biased downwardly by a spring 57. Owing to the lostmotion connection between fork 17 and roller 31, fork 17 continues to move downwardly after electrode bar 23 has been arrested by stop pin 33, and the switch contact 51 is set so that the switch closes immediately after the electrode comes to rest. Similarly the switch opens immediately before the electrode commences to rise again. Thus a maximum bonding time is provided consistent with avoidance of arcing.

Abstract: 952,310. Suction dredgers. M. M. HOFER. Feb. 1, 1963 [Oct. 1, 1962], No. 4255/63. Heading E1F. [Also in Division G3] A suction dredge has a suction pipe 2, 4 connected to the inlet of a pump 5, the pipe 2 being provided with a relief valve 7 which is normally closed but is opened in the event of the pipe being blocked. The suction at two points of the pipe 4 is fed to bellows 30, 31 and under normal conditions the pressure difference in the bellows closes a switch 33, 34 to supply current to a solenoid 21, actuating a rotary valve 18. With the solenoid energized, the valve is in the position shown and fluid pressure from a source 19 is fed through the valve 18 to a pipe 15 and acts on a piston 16 to hold the valve 7 closed. When a blockage occurs in the pipe, the pressures in the bellows become substantially equal and the switch 33, 34 is opened, thus de-energizing the solenoid 21, which rotates the valve 18 to open the pipe 15 to exhaust. The piston 16 is then moved by a spring 10 and the valve 7 is opened by a wire 9 and lever 8. The valve 7 may be opened at any time by manual operation of a switch 26.
