Title: Improvements in or relating to drafting gear employed on spinning frames
IPC: D01H5/68
Filed: 1948-06-10
Abstract: 652,661. Roller clearers; suction endcatchers for textile spinning machines. CARRIER ENGINEERING CO., Ltd., and WOOLARD, H. J. June 10, 1948, No. 15682. [Class 120(ii)] A drafting head for a textile spinning frame has a series of nozzles and suction pipes individual to each thread and supported by resilient means, so that each nozzle can be depressed to give access to the lower of the front two rollers and rise automatically into the desired operative position. A saddle fitting 19 is preferably provided on each nozzle 16 associated with a pipe 17, formed from thermoplastic material, e.g. cellulose acetate butyrate, and in each fitting 19 is mounted an individual underclearer 22, clearing front roller 8 and itself kept clean by a scraper 26 and by suction from a slot 27. A spring arm 24 is fixed at one end to the fitting 19 and at its other end rests slidably on a beam 25, so that, when the nozzle 16 has been manually depressed, the spring arm 24 will cause it, upon release, to rise again. Pipes 17 are so connected to a common suction duct 18 as to provide a limited universal movement by means of ferrules 30, which may have compressible inserts, such as cork sleeves 31. The nozzle 16 may be straddled by a comb bar connected to the traverse bar, so that the nozzles may follow the traverse movements of the rovings. A taper is given to the ends 32 of pipes 17, according to the closeness of the pipes to the suction fan, so as to compensate for varying suction values in the duct 18. In a modification, a scraper bar associated with a throughgoing under-clearer roller forms a common abutment for the nozzles.

Title: Improvements in and relating to the manufacture of styrene and the like
IPC: C07C5/333
Filed: 1942-11-06
Abstract: Styrene or alkyl substituted styrenes are produced by dehydrogenation of ethyl benzene or substituted ethyl benzenes with a catalyst consisting of ceric oxide, with or without a uranium oxide stable at the reaction temperature, on a carrier consisting of oxides of Be, Mg, Ca, Sr or Ba, the amount of ceric oxide being between 10 and 25 per cent of the total weight.  The catalysts may be prepared by impregnating magnesia with ceric nitrate solution, igniting, heating in air to 650 DEG  C. and then passing hydrogen, or by co-precipitation of the hydroxides.  The initial material may be ethyl benzene or fractions containing it, especially the fractions boiling at 125-150 DEG  C. and containing 20-70 per cent of ethyl benzene obtained from the products of aromatising, cracking or reforming of petroleum, synthetic or coal oils or coal tar naphtha as described in Specifications 552,216, 574,963, 574,973, 575,766, 575,768, 575,769 and 575,771. Substituted ethyl benzenes such as isopropyl or propyl benzene, which give a - or b -methyl styrene on dehydrogenation, and o-, m- or p-ethyl toluene, which yield o-, m- or p-vinyl toluene, may also be used.  Atmospheric or reduced pressure may be employed and inert gases such as nitrogen may be present.  In examples: (1) ethyl-benzene is passed at a space velocity of 0.2 c.c. liquid feed/c.c. active catalyst space/hour over 10 per cent ceric oxide on magnesium oxide in a quartz tube at 600 DEG  C.; (2) the space velocity is half that in (1) and the ethyl benzene is diluted with 8 times its volume, calculated as vapour, of nitrogen; (3) conditions are as in (1), but the catalyst is 10 parts ceric oxide, 5 uranium trioxide and 85 magnesium oxide; (4) the fraction boiling at 133-138 DEG  C. and containing about 40 per cent ethyl benzene, separated from the product obtained by cracking petroleum heavy naphtha as described in the above Specifications, is treated as in (1) except that the temperature is 630 DEG  C. and dilution with nitrogen in a ratio of 8 : 1 is used.
