IPC: B41J19/18
Filed: 1917-08-09
Abstract: 111,461. Remington Typewriter Co., (Assignees of Barney, E. E.). Nov. 22, 1916, [Convention date]. Letter-spacing mechanism. - The escapement wheel 39, Figs. 4 and 8, and a ratchet-wheel 11 are secured to a shaft 14 carrying a loose sleeve 6 formed with a feed pinion 5 and a supporter and housing 7 for a coupling-pawl 10, the shaft being journaled in a bracket 20, detachably secured to the top plate 3 of the machine. The sleeve 6 is provided at the ends with bearing-sleeves 15, 16 and is out of contact with the shaft between the sleeves. The escapement wheel is secured by screws 41 to a shouldered flange 40 on a sleeve 36 which is threaded on a sleeve 34 formed on the ratchet-wheel. The ratchet-wheel abuts on the sleeve 6 and is secured to the shaft and the sleeve 36 by one or more screws 35. The shaft is mounted at the ends on balls running in races 24, 30, Fig. 8, carried by the arms 17, 18 of the bracket 20, which is secured by screws passing through holes 21, 22. The race 30 is threaded for adjustment in the arm 18 and is secured by a nut 31. In manufacture, the escapement-wheel is hardened independently and the parts are assembled with the teeth of the escapement wheel and ratchet-wheel in register before the holes for the screws 41 are drilled. Back-spacing mechanism.-(1) The lever 44, Fig. 4, that carries the back-spacing pawl 42 is detachably pivoted on a member 50 which is detachably secured to the bracket 20. The member 50 is secured on a curved seat 57 on the bracket by screws 56, a lateral opening 51 being formed in the member to permit of its being passed laterally over the sleeve 6 of the escapement mechanism. The member is formed with a grooved flange 53 for engaging a bearing opening 48, Fig. 5, in the lever 44, a segment of the flange and a part 49 of the wall of the opening being cut away so that, when the parts are in the position shown in Fig. 5, the lever 44 can be pushed on to the flange. A quarter-turn is then given to the member 50 to prevent detachment of the lever. (2) The back-spacing pawl 42 cooperates with teeth 8 on the housing 7 and is connected by a link 66 to a rock-shaft operated by the back-spacing key. The lever 44 is formed with a lip 72 which normally rests on a stop 71. Relative movement of the pawl and the lever 44 is limited by a pin 46 and a slot 45 and, on operating the back-spacing key, the pawl is first engaged with the teeth 8, and the lever 44 and the pawl then move bodily, the movement being limited bv the engagement of a stop with the back-spacing key lever. A pin 68 on the link causes the pawl to jam against the teeth and prevent overthrow. (3) The feed-rack 4, Fig. 2, is prevented from lifting during back-spacing bv an arrangement similar to that described in Specification 23007/06 and comprising a hook 75 which is automatically swung over the rack. The hook is secured to a rock-shaft 76 and is pressed towards the rack bv a spring 80. movement being normally prevented by a pin 82 on the lever 44 engaging a lug 83 on the hook.

IPC: B65H3/06
Abstract: 115,128. Wade, H., (Cross Paper Feeder Co.). June 9, 1918. Pilc tables for sheet feeds ; separators. - Relates to machines in which a bank of fanned-out sheets is fed to combing-wheels which advance the top sheet for removal separately, and particularly to the machine, described in Specification 25663/02, and comprises an arrangement of feedtapes on the feed-table designed to co-operate with the combing- wheels in feeding the bank forward, and means for intermittently operating the feed-tapes. As shown in Fig. 1, the bank of fanned-out sheets is fed to the feed-table 1 from a supply table 2 through the curved throat formed between a drum 3 and curved guides 4, tapes 5 assisting the feed. The feed-tapes 6 on the table 1 are on pulleys on shafts 7, 8 and extend forwards of the combing- wheels 9 so that the wheels 9, when lowered on to the sheets, press them against the tapes. To permit of the lateral adjustment of the combing- wheels 9 for various sizes of sheets, the sets of tapes 6 on each side of the centre line are placed close together, as shown in Fig. 2, so that each wheel 9 in any of its adjusted positions will be over one or other of the tapes. In the operation of the machine, the combing-wheels are lowered on to the pile and feed the top sheet forward until it reaches the feeler 11 between the feeding-off rollers 12, 13, and they are then automatically raised from the pile. The tapes 6 are moved forward preferably during the time that the combing-wheels are down on the pile, by the following mechanism. A ratchet wheel 15 on a shaft geared to the drum 3 and to the shaft 7 is engaged by a pawl 16 on a lever 17 connected by a rod 24 to an arm 21 fixed on a shaft 23. An arm 18 loose on the shaft 23 is oscillated continuously by a rod 20 and crank 19 on the shaft 10. The arm 18 transmits its full movement tn the right in Fig. 1 to the arm 21 by means of a lateral projection 25 on the arm 21. The arm 18 is connected to the arm 21 during its movement to the left, which is the feed niovernent, by means of a latch 26 pivoted at 28 on the lever 21 and adapted to engage by the pressure of a spring with a notch 27 on the lever 18. An arm on the pivot shaft 28 of the latch is connected to a rod 32 sliding in a pivoted bracket, the rocking movement of the arm being limited by stop lugs 30 on the arm 21. As the arms 18 and 21 move to the left, the latch 26 is disengaged when the combing-rolls 9 are raised by means of a pawl 35 which engages one of the teeth 34 on the rod 32, the disengagement taking place sooner or later according to the length of the combing interval, and at each long combing interval the arm 21 is moved far enough to bring the pawl 16 into engagement with another tooth of the ratchet wheel 15.

Patent GB-968202-A (GB)
Title: Improvements in or relating to metal oxide sols and silica sols
IPC: B01J13/00
Filed: 1961-03-30
Abstract: Aqueous sols of polyvalent metals may have a particle size of 0.1-100mm  and aqueous silica sols may have a particle size of 0.1-3 mm . Such aqueous sols may be prepared by contacting an aqueous solution of a metal salt or of an alkali metal silicate with a solution of an alkylamine or of an alkyl-phosphoric, -sulphuric or -carboxylic acid respectively in a water-immiscible organic solvent, allowing the phases to separate and removing the aqueous layer containing the sol.  The formation of sols of SiO2, Cr2O3 and ThO2 respectively from sodium silicate, CrCl3 or Cr(NO2)3 and Th(NO2)4 solutions employing di-(2-ethyl-hexyl) phosphoric acid, di-tridecylamine and C18-C20 mixed primary amines or di-tridecylamine are exemplified. In each case 5 vol. per cent iso-decanol is present in the organic phase to avoid formation of third phases, and the organic solvent is kerosene.  The metals Ni, Fe, Al, Ba, Ca, Cu, Mg and U are also mentioned; they may be present as nitrates, sulphates, phosphates, chlorides or other halides.  Organic acids specified contain as alkyl groups, 2-ethyl hexyl, n-octyl, 3,5,5-trimethylhexyl, heptadecyl and 4 - ethyl - 1 - isobutyloctyl. Sulphuric or phosphoric acid may be used to regenerate these acids after sol formation.  Bases which may be used may be primary, secondary and tertiary amines and quaternary ammonium compounds, trioctylmonomethylammonium hydroxide, trioctylamine, ditridecylamine and mixed isomers of primary amines of t.-C18H37NH2 to t.-C21H43NH2. After sol-formation the basic material may be regenerated with sodium carbonate. In addition to i-decanol, the alcohols 2-ethyl hexanol, 4-ethyl octanol, capryl alcohol, undecanol, diisobutyl carbonol, tetradecanol and trimethyl nonanol may be used to prevent the formation of a third phase.  Organic solvents mentioned are hexane, kerosene, carbon tetrachloride, chloroform, benzene and polar solvents; solvents may be first scrubbed with sodium carbonate solution to avoid contamination. If so desired the sol formation may be carried out at above room temperature, up to 100 DEG  C., this resulting in an increase in size of the particles.  In a preferred embodiment, the aqueous salt solution and the organic solution are fed into a reaction zone containing a previously prepared seed sol. The aqueous phase may be fed at a constant or a logarithmic rate and the organic phase fed at a constant rate; a quiescent zone in the reaction zone provides for settling out of the phases and the organic phase may be recirculated after regeneration (e.g. by two-stage counter-current contact with sodium carbonate) and washing with water.  The size of the particles may thus be built up, and sol thus produced made the seed material in further similar processes. In examples, single-stage processes produce Cr2O3 sols of particle diameter 6.2 and 9 mm  and a ThO2 sol of 9.5 mm  diameter and in successive stages a ThO2 sol had particle diameter of 9.5, 19.7, 35 and 56 mm .  The sols of Specification 924,999 are disclaimed.

Filed: 1965-03-23
Abstract: The off-gases obtained in the liquid phase oxidation of cyclododecane are cooled to 65 DEG  C., freed from the cyclododecane which condenses, and washed with cyclododecatriene at temperatures below 65 DEG  C.  The mixture of cyclododecane and cyclododecatriene so obtained is then washed with water, preferably containing a little caustic soda and is then catalytically hydrogenated (presumably to cyclododecane). The hydrogenation is preferably carried out under a pressure of 280-320 atmos. at 200 DEG  C. in the presence of a copper-nickel-chromium catalyst.ALSO:In the liquid phase oxidation of cyclododecane with oxygen or gases containing oxygen to give cyclododecanone and cyclododecanol, the offgas cooled to 65 DEG  C. and freed from cyclododecane thus deposited is washed with cyclododecatriene at temperatures below 65 DEG  C., the mixture of cyclodedecane and cyclododecatriene so obtained is washed with water and the mixture of cyclododecane and cyclododecatriene is catalytically hydrogenated.  The cyclododecane is oxidized at a pressure of 1 atm. and a temperature of 150-180 DEG  C. using boric anhydride as catalyst.  The water used for washing the cyclododecane/cyclododecatriene mixture preferably contains caustic soda to neutralize any acid constituents.
