Patent GB-984828-A (GB)
Title: Process for the preparation of copolymerisable epoxyethers
IPC: C08F16/12
Filed: 1961-07-17
Abstract: Unsaturated epoxy ethers of the formula R-O-R1, where R is a saturated epoxidized mono- or polycarbocyclic ring system with at least 6 carbon atoms, and R1 is a branched of unbranched alkenyl group containing a maximum of 5 carbon atoms, are made by selectively epoxidizing by known methods an unsaturated ether of a cyclo-olefinic alcohol.  Epoxidation may be effected with a peracid, e.g. peracetic acid, in the presence of an inert solvent, or with H2O2 in the presence of a carboxylic acid and a catalyst.  The amount of per-compound is usually 1.05-1.2 mols. per mol. of the double bond to be epoxidized and the reaction is effected at 0 DEG -40 DEG  C.  The starting materials may be made by etherification of unsaturated carbocyclic alcohols, e.g. cyclohexenols, dehydroborneol, 1,4 - 5,8 - dimethylene - D 6,7-octahydro - b  - naphthol, or tricyclo [5,2,1,02,6]-decene-D 3,4 - ol - 9 with unsaturated fatty alcohols, e.g. allyl alcohol, 1-butene-3-ol, crotyl alcohol, or by the reaction of the alkali metal alcoholates of the said cyclo-olefinic alcohols with the corresponding unsaturated halides, or by reaction of these chlorides with the cyclic olefine alcohols in the presence of strong bases. Unsaturated alcohols may be added directly to dicyclopentadiene, cyclohexadiene, bicyclo-[2,2,1] - heptadiene or 1,4-5,8 - dimethylene-D 2,3-6,7 - hexahydronaphthalene.  In examples, (1) the allyl ether of tricyclo [5,2,1,02,6]-decene - D 3,4 - ol - 9 is obtained from allyl alcohol and dicyclopentadiene and is epoxidized with peracetic acid to 3,4-epoxytricyclo [5,2,1,02,6] - decene - ol - 9 allyl ether; (2) crotyl alcohol is added to dicyclopentadiene in the presence of BF3 to form the crotyl ether of dicyclopentadienyl alcohol which is epoxidized with peracetic acid to a monoxide; (3) sodium dehydronorborneolate is treated with allyl chloride and the allyl ether of norborneol is epoxidized with peracetic acid to form the allyl ether of epoxynorborneol; (4) example 3 is repeated with crotyl chloride.  Specifications 842,731 and 943,925 are referred to.

Title: Locking device for safety guard
Inventor: TILSTON DONALD JAMES
Filed: 1955-09-13
Abstract: 825,045. Machinery safety devices. AULT & WIBORG Ltd. Sept. 13, 1956 [Sept. 13, 1955], No. 26221/55. Class 80 (4). [Also in Group XXV] In a safety device for interlocking the guard (not shown) of a rolling mill with its power supply switch 40, Fig. 5, a rotatable barrel 11 actuating the movable member 42 of the switch and having a hand lever 7 is locked in the switch-open position when the guard is inoperative by two or more spring-loaded pins 27b, 28b, Fig. 6, connecting aligned holes in the barrel 11 and in a fixed body portion 4. When the guard is moved to its operative position and is correctly located, a portion thereof enters a recess 21 in the body 4 and, acting through pins 27a, 28a slidably retained in said holes in the body, depresses the pins 27b, 28b fully into the barrel 11 to allow it to be rotated by the lever 7, whereupon the member 42 moves into a channel in the barrel 11 and closes the switch 40. The coacting end surfaces of the pins 27b, 28b and 27a, 28a are curved to correspond with the surface of the barrel 11. As the lever 7 is rotated a recess 44 therein engages over the guard portion to locate it correctly and to lock it in position, the lever 7 and barrel 11 being coupled by a spring 50 allowing rotational lost motion while the guard portion is being correctly located. The pins 27a, 28a are preferably of different lengths and their upper ends are engaged by corresponding slots in the guard portion so that the latter forms a " key." The pins are slidably retained in the body 4 and held against rotation by screws 37 engaging recesses therein. The switch-actuating channel in the barrel 11 may be replaced by a spring- loaded ball and the switch 40 be closed by depression, rather than release, of the member 42. The rotation of the barrel 11 is limited by a screw 52 engaging a channel therein.

In an example SO 2  is monitored by introducing it through pipe 12 into the indicator cell 7 containing acidified iodine solution, thus producing iodide ions which are oxidized at the anode (indicator electrode). Iodide ions released at the reference electrode are removed to waste by the circulating electrolyte. As shown, Fig. 1 electrolyte stored in a tank 19 is circulated by a peristaltic pump 16 through a series of cells 6 .. 9 with electrodes 1 .. 4. In the first cell, auxiliary electrode 1 connected directly to the D.C. source, Fig. 2, oxidizes any reactive substances circulating in the electrolyte. Sample gas is introduced through pipe 12 into cell 7, and the reaction products are oxidized at indicator electrodes 2, 3 giving rise to the measuring current through microameter 23. Auxiliary electrolysis electrode 4 downstream, prevents any iodide-ions liberated at the reference-electrode 5 from difusing back upstream. About 10% of the electrolyte is drawn through the reference electrode cell 10 and pumped to waste to remove iodide-ions, the remainder is recirculated to the storage tank 19. The electrodes may be platinum or carbon, and iodine (not shown) may be housed in the reference electrode cell to act as a depolarizer.

Filed: 1928-09-17
Abstract: 316,174. Union Chimique Belge Soc. Anon. July 24, 1928, [Convention date]. Purifying processes; materials for purifying.- In a process of treating coke oven gases or the like with an ammoniacal solution which is then caused to react with calcium sulphate to produce ammonium sulphate, as described in, Specification 262,320, the cold gases issuing from the apparatus for condensation of tar and ammoniacal liquor from the crude gas, are subjected to scrubbing with a. solution rendered alkaline with anhydrous ammonia. The hot coke oven gas from pipe 1 is cooled in a condenser 2 and passes to a scrubber 6 where it is treated with ammoniacal solution fed from a receptacle 16. This solution absorbs the acid impurities and flows into a mixer 19 in which it is treated with calcium sulphate to give a solution of ammonium sulphate and calcium salts which are separated from the insoluble materials in a filter 21 and treated as in Specification 262,320. The gas and volatile ammonia pass by a pipe 7 to a scrubber 8 fed with cold water or ammonium sulphate and the purified gas enters a cooler 10, through which extends a pipe 22 carrying cold anhydrous ammonia, and is deprived of the hydrocarbons such as benzol which flow out through pipe 32, the completely purified gas escaping through pipe 11. The ammonia from pipe 22 is fed by pipe 23 to the receptacle 16 where it meets the liquid from the scrubber 8 which is delivered through a pipe 15. Ammoniacal liquor from the cooler 2 is fed by a pump 26 and pipe 27 to a still 28 from which the volatiles pass through a condenser 29 and pipe 30 to the ammonia pipe 23; these acid gases supply a further source of ammonium carbonate suitable for sulphatation by the gypsum.
