Title: Production of pure glycol solutions
IPC: B01J39/00
Filed: 1944-09-07
Abstract: Aqueous glycol solutions containing acidic impurities including acids and salts are purified by passing the solutions through a bed of anion-exchange material A1, thence through a bed of cation-exchange material C1 and thence through an anion-exchange material A2.  In modifications, the effluent from bed C1 or A2 may pass through a bed of anion-exchange material A3 which has been buffered so that the fluid flowing therefrom will have a neutral or other desired pH, or the effluent from the bed A2 may be passed through another bed of cation-exchange material C2 and thence through a bed of anion-exchange material A4 which may be buffered as in the case of bed A3, and, if desired, one or more series of beds of anion- and cation-exchange materials may be inserted between beds C2 and A4. Preferably, when using a bed of buffered anion-exchange material, the effluent flowing thereto should contain a low content of ionizable solids, preferably less than 20 p.p.m.  The anion-exchange material may be activated by means of aqueous alkali and then buffered by treatment with carbon dioxide or an aqueous solution of sodium hydroxide or carbonate to give the desired pH.  Suitable anion-exchange materials include the aldehyde-condensation products of m-phenylene diamine, biguanide guanyl urea, methyl guanidine, phenyl biguanide and polyamines such as the polyethylene polyamines; they may be formed from formaldehyde, furfural, acrolein and benzaldehyde. When the products are insufficiently insoluble they may be rendered insoluble by treatment with formaldehyde reactive materials such as urea, thiourea, the aminotriazines, especially melamine and guanamines.  The methods of preparation described in Specifications 561,896 and 562,402 may be used.  Suitable cation-exchange materials are catechol tannin-formaldehyde condensation products, aromatic sulphonic acid-formaldehyde condensation products as described in U.S.A.  Specification 2,204,539 and carbonaceous zeolites such as sulphated or sulphonated coal, peat, or lignite.  In an example, an aqueous solution containing a mixture of ethylene glycol, diethylene glycol and propylene glycol, acid and some salt is passed through a bed of activated anion-exchange resin, for example, that prepared according to example 1 of Specification 561,896, then through a cation-exchange material, for example a bed of resin (C) prepared as described hereinafter and acid activated, and thence through a second bed of anion-exchange material whereby the ash content of the solution is reduced from 0.075 to 0.0002 grams per 100 c.cs.  Resin (C) is prepared by reacting acetone and furfural in aqueous caustic soda, then refluxing with sodium bisulphite and thereafter heating the product with additional furfural and aqueous sulphuric acid; the resin obtained on gelling is granulated and dried.  Specifications 569,661 and 572,915 also are referred to.

Abstract: 210,360. Reed, J. H., and Little Co., A. E. Jan. 9, 1923. Boot-sole sewing-machines; lock-stitching by shuttle.-In a shoe-sewing machine of the Kay type, the shuttle comprises a rotatable bobbinmember arranged in a planes slightly inclined to the needle axis, so that the beak of the said member engages the needle-thread loop at its lowest position and clears the needle without axial movement in its highest position. The shuttle bar 20, Fig. 4, having a loop-taking point 41 has a flange 44 working in a groove in a race 42. The groove is closed by arcuate keepers 46, 47, the former of which is fixed while the latter is pivoted and is held in position with its free end against a stud on the race by a spring-pressed bolt 14, Fig. 1. The shuttle is closed by a cover 12, Fig. 7, which is positioned by means of fixed and movable locking-plates 33, 34 which engage in undercut recesses in the shuttle. The plate 34 consists of concentric portions of different radii and can be rotated by inserting a tool in the recessed stem 36. The shuttle thread is wound on a hollow rod 26, Fig. 9, extending axially from the cover 12, and the inner end of the thread is led out through a hole 27 where it is tensioned by a spring-pressed plunger 28. The race is cut away at 56, Fig. 4, leaving a point 57 which coacts with the shuttle point 41 in entering the needle loop. The shuttle flange and body are also recessed between the points a, b, Fig. 7, to receive in conjunction with the race.gap 56 one leg of the needle loop and to enclose it in the race on further rotation of the shuttle. The shuttle is oscillated by a finger 61 of less ,width than the distance between the shoulders a, b, and engaging between them. The finger 61 is cut away at 62, Fig. 4, to allow the shuttle-thread T a straight passage to the work. The finger 61 is integral with a disc 60, Fig. 1, fixed to a shaft 10. A rack 65 on a cam-actuated arm gears with a pinion 64 on the shaft 10 to oscillate the shuttle. The race is mounted on a slide 51 dovetailed into a guide 54 on the casing so that it can be moved into and out of operative position; the pinion 64 is elongated to allow of such movement without disengagement. The slide 51 can be locked by a screw 52, and its operative position is accurately determined by a stop-screw 55. The finger 61 and the disc 60 are respectively spaced radially and axially from the shuttle. When the looptaking point 41 enters the needle-loop, the needle dips slightly to free the loop. Specifications 34/86 and 106,510 are referred to.

Title: A fluid logic element
Inventor: PAVLIN C F
IPC: F15C1/10
Filed: 1968-04-10
Abstract: 1,219,003. Fluid logic elements. SOC. BERTIN & CIE. 10 April, 1968 [21 April, 1967; 28 Feb., 1968], No. 17244/68. Heading G4P. A fluid logic element has a reflection chamber 10 with converging walls 17a, 17b, so that when a control channel 6 is actuated, a fluid jet from nozzle 8 is reflected from one of the walls to cause unequal pressures in the chamber whereby the stream is switched to that outlet channel on the same side of the chamber as the actuated control. The device is bi-stable when nozzle 8 is symmetrically disposed and the walls 17a, 17b equally inclined, and monostable when one of the outlets is preferred due to symmetry bias of the nozzle (Fig. 3, not shown) or to unequal inclination of the walls (Fig. 12, not shown). One of the control channels of the monostable device may be replaced by two channels (20), (21), Fig. 5 (not shown) to provide an AND/ NAND gate or, alternatively, by several channels each connected to a cylindrical fluid diode with a central orifice, closure of any one of which causes back pressure switching to the unpreferred outlet channel, thus providing an OR-NOR gate (Fig. 7, not shown). The channels (20), (21) may each have an injector (32) with a larger cross-section diffuser (33) to provide a valve to prevent back pressure from causing undesirable "flip-flopping" (Fig. 11, not shown). Negative feedback connections between outlet and control channels or the chamber 10 may be introduced to enhance stability (Figs. 13, 14, not shown) and isolating circuits, Fig. 15 (not shown), forming fluid diodes, may be connected to one or more of the control channels to prevent back pressure in the chamber 10 from interfering with the control channels (Figs. 16, 17, 18, not shown). The logic element is formed of three plates of plastics, metal, or the like, the rear sheet being solid, the middle sheet having the fluid channels, and the front sheet having apertures formed therein for connection to tubing. The fluid may be liquid or gas.
