Title: Production of water-soluble resin sulphonates
IPC: C08F8/34
Filed: 1952-05-20
Abstract: Water-soluble sulphonates of polymers or copolymers of a compound of formula <FORM:0708164/IV(a)/1> wherein Ar is a monovalent aromatic radical and R is hydrogen or methyl, are prepared by admixing 0.8 to 3 molecular equivalents of sulphur trioxide with a solution of one equivalent of the resin in a liquid carbon chloride, e.g. carbon tetrachloride or tetrachloroethylene, to form a mixture with the solvent weight at least 9 times the combined weight of sulphur trioxide and resin, and maintaining the mixture at -20 DEG  to 45 DEG C.  Examples of the resins are styrene, a - methyl styrene, ar-chlorostyrene, ar-vinyl toluene, and ar-ethyl vinyl benzene, copolymers of styrene with vinyl toluene or a -methyl styrene &c. copolymers with minor amounts of other vinylidene compounds, e.g. amylene, di-isobutylene, or 1,3-butadiene.  The sulphur trioxide may be added continuously and at a varying rate to the resin solution as a gas, liquid or a solution to give a granular product.  Examples describe the sulphonation of polystyrene, polymeric ar-vinyl toluene and ar-chlorostyrene and copolymers of styrene with a cracked oil gas containing pentene, pentanes, conjugated cyclopentadiene and 1-4 pentadiene, and with vinyl toluene in batchwise or circulatory processes to which ammonia is added at the final stage and the sulphonated product separated. Specification 683,164 is referred to.

Title: Means for automatically flushing water closets
IPC: E03D5/10
Filed: 1930-04-26
Abstract: 347,876. Door-action water-waste preventers. BOURDET, A. L. R., 3, Cours du Marechal Gallieni, Bordeaux, France. April 26, 1930, No. 12941. Convention date, April 26, 1929. [Class 26.] Water closets are automatically flushed when the door is opened, the flushing lever or cock being connected to the armature of an electromagnet operated by a switch connected to a member for opening the door from the inside. When the handle 3 unlocks the bolt 2, a stud 4 on the latter engages a cam 14 on an insulated plate 12 carrying a spring- contact 13 which is thereby momentarily lowered against a contact 10. When the bolt 2 is fully unlocked, the contacts spring apart and on locking the bolt, the stud 4 passes under the cam 14. Electromagnets 15, 16, Fig. 5, have a common armature 17 pivoted at 18 and closing contact 19 or 20. Switch 22 is closed when the door fastening is locked, and current passes through the armature 17, contact 19, and electromagnet 16, which is energized to move armature 17 to contact 20. When the door is opened, switch 21 is closed and current passes through armature 17, switch 21 and an electromagnet 26, which is thus energized and releases a flush of water. When the armature 25 has entered the electromagnet, an arm 24 closes a switch 23, and current passes through the electromagnet 15, thus moving the armature 17 and opening the circuit of the electromagnet 26. In an alternative construction, a door knob is pushed from within against spring action to complete the circuit of the flushing electromagnet. Push or ordinary cocks may be employed, the opening of which may be prolonged by clockwork or a time-retarded electric relay, so that no tank is required. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a mechanically controlled flush on unbolting the door. A bolt 44, Fig. 7 (Cancelled), is moved into a recess 61 to lock the door, a stud 48 on the bolt 44 passing between a plate 53 and a movable ramp 49 with a pivoted extension 58. When the door is unbolted, the stud 48 engages the upper surface of the ramp 49 and so lowers it with an attached ring 56 to operate a flushing cord. Alternatively a single handle on the door frame operates the water flush through a cord as the door opens ; or a member in the staple may eject the bolt. A milled disc on the bolt may close it in the staple, and a separate handle may withdraw the bolt against a spring. This subject-matter does not appear in the Specification as accepted.

Moving-chamber apparatus.-An apparatus for delivering a definite quantity of liquid consists of trough-like vessels a, mounted on trunnions b<1>, and fitted with a ball-cock which, when a handle is moved for delivery, is maintained in its closed position until the vessel, after discharge, has been rotated back to the filling- position again. The vessel a, as shown in Fig. 4, is of three-quarter circular cross-section and fills up to the level of an overflow aperture a<1>, which, together with a row of apertures c, descends when the vessel is rotated on its trunnions to the lowermost or other intermediate position to discharge the whole or part of the liquid. The ball g of the cock h is prevented from descending, as the liquid leaves the vessel, by an arm i, the hook end l of which engages with the lower end of the slot in a' guide m mounted on the inlet pipe. When the vessel a is rotated back, a pin p on its end wall engages with a triangular pawl n, which lifts and disengages the arm i, and enables the vessel a to fill again. The movements of the trough are effected by a handle d and limited by adjustable stops f on a sector e attached to the inlet pipe.
