Title: Novel solvent recovery method
IPC: C08F6/02
Filed: 1964-06-25
Abstract: 1,017,580. Solvent recovery; purification of polyolefines. REXALL DRUG & CHEMICAL CO. June 25, 1964 [June 27, 1963], No. 26383/64. Heading BIB. Solvent, e.g an alkanol or a glycol, is recovered from a solution, obtained by solventextraction of metallic catalyst residues from a polyolefine, by mixing the solution with a hot hydrocarbon oil so as to volatilize the solvent. The hydrocarbon oil is preferably an aromatic oil boiling in the range of about 400-700 ‹F. Before contacting the solution with the oil, it is advantageous to concentrate the solution in order to raise the solids-content to about 20-65% by weight. In an example, the product of the polymerization of propylene, in the presence of an aluminium alkyl and titanium trichloride, is treated with a combination of isopropanol and n-heptane. The resultant solution may be concentrated up to a solids-content of 10% by weight in evaporator 1, which is operated at a pressure of about 5 p.s.i.g. The solution is then concentrated up to a solids-content of 45-65% by weight in evaporator 4. The isopropanol and heptane vapours from evaporators I and 4 are condensed in cooler 31, and the condensate is collected in tank 30. The concentrated solution withdrawn from evaporator 4 is mixed in line 15 with a heavy aromatic oil at a temperature of 500-600 ‹F., and the mixture is pumped to flash separator 6 where the remaining isopropanol and heptane are flashed off. The vapours are condensed in cooler 32, and the condensate is collected in tank 30. Part of the hydrocarbon oil and residual feed mixture withdrawn from the bottom of separator 6 is recirculated to the separator, and the remainder is burned at a temperature of 1000-1300 ‹F. in incinerator 8. The hydrocarbon oil, to be mixed with the concentrated solution from evaporator 4, is pre-heated by indirect heat exchange in incinerator 8, and is then fed to the mixing-zone via line 21. The weight of oil which is mixed with the solution is about equal to the total weight of contained soilds. The oil to be used is preferably subjected to a prior heat-treatment at a temperature of at least 800 ‹F.

Title: Improvement in a device for shuffling and dealing playing cards
IPC: A63F1/12
Filed: 1935-09-24
Abstract: 451,386. Dealing and shuffling cards. FORRESTER, H. J. C., 88, Chancery Lane, London.-(Kolisch, P. ; 41, Park Row, New York, U.S.A.) Sept. 24, 1935, No. 26471. [Class 132 (ii)] In a card dealing and shuffling device of the kind in which cards are removed one by one from a pack and each card forwarded to one of a number of receptacles or compartments selected by cam-operated means, the cards are fed mechanically to shoot means discharging into a munber of compartments and cam-operated selectors or fingers are provided to determine the compartment which will receive a particular card. The pack of cards C, Fig. 4, is placed on a plate 1 and pressed downwardly by a weight 48 pivoted to a rock-arm 49. Upon the manual rotation of a crank shaft 40, the cards are removed singly from the bottom of the pack by a reciprocating slide 2 and are fed into a shoot 55 by feed rollers 53, 54. Each card, as it passes down the shoot, is directed by fingers 25, 24, 32 into one of four compartments N, E, S, W. The finger 25 is controlled by a cam 11 and the fingers 24, 32 by a cam 10, both cams being mounted on a shaft 62 driven from the crank shaft 40. The profiles of the cams are such as to cause the cards to be delivered into the compartments in a predetermined shuffling sequence, the resulting hands being removed from the compartments in rotation by the players. The finger 25 is fast on a shaft 23 having an arm 67, Fig. 6b, connected to a pivoted cam-follower 13 by a spring 19, the arrangement being such that the finger is yieldingly urged to its upper and lower positions as the cam 11 rotates. The finger 24 is similarly actuated by the cam 10, while the finger 32 is linked to the finger 24 for movement in unison therewith. A pickerplate on the feed-slide 2, and a control plate 57 at the forward end of the pack are both adjustably mounted. In a modification, Fig. 11, the card compartments 5<1> are rockable to the accessible position shown in dotted lines, at the conclusion of a dealing operation, by a spring-actuated toggle 42<1>, 431. The compartments are normally held in the inaccessible position, shown in full lines, by a latch 14<1> that is disabled by a spring 38<1> upon the removal of the weight 8<1> from above the pack C with the consequent release of a rod 121 pivoted to the latch. Rotation of the operating mechanism is prevented, while the compartments are in accessible position, by a lever 46<1> controlled by the toggle and provided with a projection 48<1> adapted to enter into locking engagement with one of a number of apertures 49<1> in the drum of a speed governor 34<1>. The device may be driven by a motor, the switch of which is controlled by the toggle 42<1>, 43<1>.
Patent GB-890559-A (GB)
Title: Method of annealing synthetic organic filamentary material and apparatus therefore
IPC: D06M23/00
Filed: 1958-08-18
Abstract: A filametary tow of synthetic organic polymeric material such as acrylonitrile polymer is heat-relaxed or annealed by continuously moving it in a path through a heat treatment zone in which heat is applied momentarily to contiguous and preferably very short portions of the tow only during its movement to raise the temperature of the portions to 130 DEG -150 DEG C., whereafter <PICT:0890559/IV (a)/1> <PICT:0890559/IV (a)/2> <PICT:0890559/IV (a)/3> the tow is moved through a relaxing zone in the form of an unsupported free-running horizontal length of tow so as to permit the internal strains in the filaments to be relieved.  As shown in Fig. 1, a tow 10 of continuous polyacrylonitrile filaments which have been stretched and are therefore in an internally strained condition is advanced in the direction of the arrow H by a pair of co-operating driven nip rolls 11, 12 of which roll 11 is covered with a layer of resilient material 24.  The lower roll 12 contains a central bore 16 (Figs. 2 and 3) and a number of radial passages 17 in its peripheral wall 18.  A heating medium such as superheated steam is supplied through a pipe 22 into a stationary chamber 19 centrally positioned within the roll bore 16 by bearings 21.  A longitudinal slot 23 in the wall of the chamber 19 is arranged to communicate successively with each longitudinal row of passages 17 as the roll 12 is rotated and is positioned so that it communicates with a single longitudinal row of passages 17 only when the outlet ends of the passages are in alignment with the nip 14 of the rolls 11, 12, the inlet ends of the remaining passages 17 being closed by the peripheral wall of the chamber 19. The tow 10 moving out of the nip of the rolls 11, 12 is taken up by a pair of nip rolls 26, 27 which are driven at a lower peripheral speed than that of the rolls 11, 12 in order to compensate for the shrinkage of the reach of the tow 10 in the relaxing area 28.  The tow is subjected in the nip 14 to the action of steam at 130 DEG -150 DEG C. for about 0,1 second.  The tow may be heated successively by a number of pairs of processing rolls, e.g. 3 pairs, each identical in construction and operation with the processing rolls 11, 12.  The tow is then allowed to sag in three relaxing areas, two between the three pairs of processing rolls and the third between the third pair of the processing rolls and a pair of take-up rolls, the amount of sag in the tow decreasing as it passes through the system of rolls.  The temperature of the tow may be raised prior to the annealing operation by passing it through a steam conditioner during its passage from the stretching to the annealing zone.  The process prevents the discoloration of polyacrylonitrile filaments.
