Title: Process for the production of pure high grade vinyl chloride
IPC: C07C17/00
Filed: 1930-10-13
Abstract: Vinyl chloride is produced by treating 1 : 1 : 2 trichlorethane at a temperature of at least 50 DEG  C. with zinc, iron or aluminium in the form of fine or coarse particles and in the presence of water or steam.  In examples (1) 1 : 1 : 2 trichlorethane flows into a vessel containing a suspension of zinc dust.  At 50 DEG  C., vinyl chloride is evolved, and at 60 DEG  C., the reaction proceeds quantitatively. (2) A mixture of iron filings, water and 1 : 1 : 2 trichlorethane is subjected to a temperature of 100-120 DEG  C., the pressure developed being say 70 lbs. per sq. in.  The vinyl chloride is blown off periodically into a cooling apparatus.  (3) 1 : 1 : 2 trichlorethane is passed together with steam over iron filings at a temperature of 300 DEG  C.  Undecomposed trichlorethane is removed by cooling, the remaining gases are washed with water until neutral, and the vinyl chloride is condensed.

Title: Improvements in or relating to propelling pencils
IPC: B43K21/08
Filed: 1932-10-31
Abstract: 389,771. Propelling-pencils. GODDEN, A., 13, Kent Avenue, Ealing, London. Oct. 31, 1932, No. 30642. [Class 146 (iii).] Relates to propelling-pencils of the kind in which the lead is held by a sheath 10 provided at its inner end with a pin 16 which engages a slot 17 in a helical member 7 and in which the lead is adapted to be ejected from its sheath by an axial pin 11 having its end 15 bent to engage the helical slot in spaced relation to the pin 16, whereby relative movement of the member 7 causes the two pins 15, 16 to travel in unison in spaced relation during the greater part of their longitudinal movement, the outward movement of the sheath being arrested at a predetermined point in its travel and the movement of the pin 11 being continued so as to eject the lead from the sheath. According to the invention, the pins 15, 16 leave the groove 17 in turn against the action of a spring- pressed collar 18, whilst, upon inward movement, the pin 15 leaves the groove and slides without constraint therebeyond and the pin 16, upon leaving the groove, causes the helical member 7 to move longitudinally of the outer casing 1 against the action of the collar 18. The helical member 7 has a limited sliding movement determined by a pin 12 on the liner 4 or the casing 1 which engages a slot 13 in the member 7 ; alternatively, the slot may be provided in the casing or liner and be engaged by a pin on the member 7. At the limit of the outward movement of the sheath 10 and pin 11, both pins 15, 16 leave the groove and press against the collar 18, and continued rotation results in the ratcheting of the pin 15 as the tail of the helical groove passes it ; when the rotation is reversed, the pin 15 rises into the groove and is followed after one revolution of the helical member, relative to the pins, by the pin 16, the pins being held against rotation by a groove 9 in a member 8 which together with the nose 2 is rotatable relative to the member 7, outer casing 1 and sleeve 4. Towards the end of the inward movement, the pin 15 leaves the groove 17 and continues its backward movement through the frictional grip upon the lead of the sheath 10, the pin 16 of which still engages the groove, until the end 21 of the sheath abuts the end 5 of the casing. The pin 16 is, on continued rotation, forced to leave the groove but, being now fixed in position, forces the helical member 7 longitudinally of the casing so as to cause the collar 18 to again compress the spring 19, when a ratcheting action of the pin 16 and the tail of the helical member results.

[Classes 32 and 91] , In the destructive hydrogenation or pressure extraction of solid carbonaceous materials with solvents while flowing the reacting materials through a tower-like reaction vessel fromwhich the main portion of the products is removed into an adjacent hot separator, a portion of the reacting materials is removed from the lower part of the reaction space before the end of the reaction and the reaction products, after leaving the separator, are freed from solid constituents. The process is applicable to the limited hydrogenation of carbonaceous materials in which at most 5 per cent hydrogen is consumed in the reaction. Brown coal is( dried with 3 per cent Bayer Mass (the dried red sludge obtained in the disintegration of sludge according to the Bayer process) and pasted with " run. back oil " and " separator sludge " obtained in the process. It is then pumped from the mixer 2 with hydrogen from a pipe 5 through a preheater 6, where it is heated to 455‹ C. and passed tangentially into, a reactor 8 provided with a stirrer 9, the reacting material flowing upwardly and being drawn off through a line 13 to a hot separator 14 maintained at 430‹ C. 11 per cent of the reacting materials are drawn off continuously from a collector 10 through a line 11 to a low temperature carbonization vessel where they are carbonized together with ash &c. residues withdrawn from the centrifuge 30. Vapours withdrawn from the hot separator 14 are cooled in a condenser 19 and passed to a cold separator 21 from which gases are taken off through line 22. The condensate is fractionally distilled in a tower 25 into benzine withdrawn through line 26, diesel oil withdrawn through line 27, and heavy oil, which together with heavy residues from the separator, is passed to the centrifuge 30. Distillate recovered from the retort 32 is recycled to dilute the residues from the vessel 14 while the centrifuged oil is recycled as " run back oil through line 35, and the " separator sludge through line 29 to the pasting vessel 1.
