Title: Apparatus for treating solid material in a finely divided state with heating or cooling gases
IPC: A23G1/04
Filed: 1922-08-09
Abstract: 199,340. Lehmann Co., Inc., J. M., (Assignees of Hollstein, P. G.). June 14,1922, [Convention date]. Cocoa manufacture. - Cocoa which has been freed from the bulk of the cocoa butter and passed through a disintegrator is passed on conveyers through a chamber through which air is driven in a closed circuit passing over cooling coils. The hot air from the disintegrator 17 escapes through bags 18 of filtering material and the cocoa is carried by a conveyer 20 to a chamber 21 containing two compartments in one of which are conveyers 22, 23, 24, Fig. 4, and in the other cooling coils 58. Air is circulated through the two compartments and connecting pipes 59, 72 by a fan 15. The conveyers are composed of hinged plates 28 carried on chains running over sprockets and supported by angle-irons 25<1>. The plates 28 are provided with trip members 30 which strike against stops 33 placed near the end of the upper flight of each conveyer and tilt the plates, thus throwing the cocoa on to the plates of the lower flight, which have been placed in position to receive it by guides 35 and are supported by straps 34. At the end of the lower flight the strips 34 are interrupted, so as to allow the cocoa to fall on to the next conveyer. The lowermost conveyer is not supported by a strip 34, but every alternate plate is furnished with lugs which rest on the flange 25" of the member 25<1> and prevent the plate from tilting, so that the cocoa resting on these plates is carried to the end of the lower flight and falls into a hopper 42, while the cocoa on the other plates falls into a hopper 41. The cocoa from the hoppers 41, 42 passes to two rotary sieves, one of which is shown at 44, Fig. 1. On the shaft 45 of the sieves are arms 49 carrying weights 50 which slide along the arms as they rotate and strike against the sifting surface to shake and clear the sieves. The overtails from the sieves are returned to the disintegrator 17. The air from the conveyers 22, 23, 24 is directed by baffles to the bottom of the chamber 21 and thence passes upwards through one of two bag filters 63, 63<1> in separate compartments connected through valve chambers 67, 68 with the fan 15. In the valve chambers valves 75, 76, Fig. 6, are so arranged on the same spindle 77 that when one is closed the other is open and the spindle 75 is also so connected with valves 91 in the sides of the chambers that when one of the valves 75, 76 is open the valve 91 in the side of the chamber containing that valve is closed, and conversely. The valves are operated by cams 82, 82<1> acting on slides 78. On the same shaft as the cams 82, 82<1> are cams 94, 94<1> acting on levers 64, 64<1> by which the filter 63, 63<1> which is cut off from the fan 15 and exposed to the outer air through the valve 91 is shaken.

Title: Improvements in the co-polymerisation of substances containing allyl compounds
IPC: C08F2/00
Filed: 1944-11-22
Abstract: A mixture of an unsaturated polyester and a compound containing an allyl or substituted allyl group is polymerized in the presence of metallic copper and either tertiary butyl hydroperoxide or tertiary amyl hydroperoxide.  An unsaturated polyester is defined as the product formed by reacting a dihydric alcohol with a dibasic acid either or both of which are unsaturated.  Specified alcohols are ethylene, diethylene and triethylene glycol and specified acids are maleic, fumaric and itaconic acids.  Preferred allyl compounds are allyl esters of dibasic or tribasic acids, e.g. diallyl phthalate. The process may be applied to the electric insulation of copper wire coils or other copper conductors by first coating them, either bare or enveloped in such materials as cotton, silk or paper, with a mixture of an unsaturated polyester, the allyl compound and the hydroperoxide and then heating to copolymerize.  In order to avoid oxidation, this copolymerization can be carried out either by immersing the copper in the mixture or by using a vacuum and heating in an inert atmosphere, e.g. nitrogen.  In examples: (1) a polyester is prepared by heating diethylene glycol and maleic anhydride, the product mixed with diallyl phthalate and tertiary butyl hydroperoxide in tertiary butyl alcohol, copper wire immersed in the mixture and the whole heated; (2) and (3) a copper wire is immersed in a mixture of diethylene maleate, diallyl phthalate and tertiary amyl hydroperoxide in tertiary amyl alcohol and heated; (4) as in (2) and (3) using as catalyst tertiary butyl hydroperoxide in tertiary butyl alcohol.
