Patent GB-1092692-A (GB)
Title: Anti-freezing additive for bulk particulate material
IPC: B01J2/30
Filed: 1965-01-18
Abstract: An additive to render sodium chloride resistant to caking and/or freezing comprises a water-soluble non-ionic synthetic detergent, calcium chloride and a water-soluble ferrocyanide, the calcium chloride being present in an amount of 20 to 50 times the detergent and the ferrocyanide being present in an amount sufficient to provide ferrocyanide ion in an amount 1 to 2.5 times the quantity of detergent. The preferred ferrocyanides are sodium ferrocyanide decahydrate and potassium ferrocyanide trihydrate, and the preferred water-soluble non-ionic synthetic detergents are a polyol prepared by condensing ethylene oxide with an hydrophobic base formed by the condensation of propylene oxide with propylene glycol, and sodium carboxymethyl cellulose.  The additive is added to the sodium chloride in an amount sufficient to make ferrocyanide ion available with the range 0.13 to 0.22 lbs/ton of salt, i.e. in an amount such that the concentration of detergent is not more than 50 parts per million part of NaCl by weight.  The additive may be applied as a spray to the granular sodium chloride and it is preferred that the amount of calcium chloride added is such that together with an CaCl2 occurring naturally in the rock salt treated the total CaCl2 present is at least 3 lbs CaCl2 per ton of sodium chloride.  The additive of the invention is also alleged to reduce the tendency of brine to corrode and attack metals.

IPC: D04B11/10
Filed: 1955-01-27
Abstract: 805,754. Knitting. V.E.B. VEREINIGTE STRUMPFWERKE ESDA. Jan. 27, 1955, No. 2546/55. Class 74 (2). The usual combination of jack and dividing sinkers is dispersed with, and all the loops of a course are formed simultaneously by the permanent elongation of inset and wholly or partly withdrawn synthetic polymer thread which has been laid along the line of needles. Any potential elongation in excess of that required for loop formation may be removed by controlled stretching of the thread on its way to the needles ; and, if necessary, it may be rendered more plastic by heating (e.g. by means of heated spool housings, or by passing the thread through a heating chamber on its way to the needles). In Figs. 1, 3 and 7, the thread is stretched by the simultaneous advance of sinkers 3 (one between each pair of needles) and the needle stems are either supported by parts 4 of a comb 5 or by a bar 9, or are shielded by rods 10 around which the loops are sunk. In Figs. 13 and 19, sinkers 3 of one set alternate with those 11 or 14 of another set ; and the two sets move simultaneously in opposite directions to stretch and kink the thread into loops; the stretched thread, when thrown off by the sinkers 3, may be held by relatively shallow sinkers 17, Fig. 21, positioned between them. In Fig. 22, the thread is stretched over upper horizontal sinker edges 18, as the needles are lowered. In Fig. 28, the sinkers, having laid the yarn against the needle stems, are withdrawn and the yarn is stretched over the knocking-over bits 7. In these last two cases, the needle heads may be reinforced. In order to provide for somewhat greater movement of the loop forming members in forming reinforced parts, the sinkers and knocking-over bits, or the rods 10, may be provided in mutually independent groups, which may be of variable widths to permit the production of reinforcements having non-rectilinear boundaries. Reference has been directed by the Comptroller to Specifccation 738,072.

Title: Improvements in or relating to processes for fixing dyes or impregnating agents upontextile materials of all kinds
IPC: D06P5/20
Filed: 1944-02-15
Abstract: Dyes are fixed upon dyed textile materials by subjecting the material to treatment with wet steam alternating several times between a lower and a higher pressure.  The alternation of pressure is effected in as rapid a sequence as possible, and the lower pressure, which may be below or above atmospheric pressure, may be produced by sudden condensation of the steam which exerts p  the higher pressure.  In a particular form of the process, the materials are subjected to a preliminary steaming in a pressure container, the steam is suddenly condensed to produce a high vacuum, the steam filling being kept fully saturated with moisture, the dyeing liquor is then introduced and if desired circulated, the liquor then removed and steam admitted.  The process is repeated one or more times and the materials finally subjected to usual after-treatment processes. Specification 542,554 is referred to.

Abstract: 644,630. Ticket receptacles. BELL PUNCH CO., Ltd. Feb. 4, 1948, No. 3289. Convention date, Nov. 4, 1947. [Class 106 (iii)] [Also in Group XV] A receptacle for tickets comprises at least one spindle for receiving apertured ticket stubs, means for rigidly mounting the lower end of the spindle, and a plate having a substantially " V " - shaped recess for receiving and affording support for the free end of the spindle which is spring-biassed against the recess but movable outwardly to permit a ticket stub placed on the end of the spindle to be moved to that side of the plate remote from the free end of the spindle. In the embodiment described a plurality of resilient spindles 16 are rigidly mounted in bushings 20 secured to a rotatable disc 21 mounted on a vertical shaft 23. The spindles are urged by their own resilience into notches 30 formed in an upper supporting disc 25, but can be pulled away to slide the tickets down. A knob 31 with an indicator disc provides for manual rotation of the shaft 23 to bring the spindles 16 successively into a recessed portion 35 of the ticket receptacle where the tickets received can be pushed on to the spindle. Reverse rotation of the shaft 23 is prevented by a pawl 42 co-operating with the bushings 20. When all the spindles have been filled, further rotation of the knob 31 brings a " FULL '' label on the upper disc 25 into view, and a stop on the lower disc meets a lug on the door of the receptacle preventing further rotation until the door is opened for removal of tickets. To do this, the end of a string is wedged into a notch 41 in the upper end of each spindle, and the tickets are slid upwards on to the string for removal. Slots are provided in the door for the insertion of special tickets.

During the splicing operation an intermediate roller 42, Fig. 16, is moved under the roller 32 and whilst the frame 2 is in its partially lowered position the web roll 82 is accelerated by an auxiliary driver 71, Fig. 18, whereupon the frame 2 is lowered further until the roller 42 contacts the replacement roll 82. Following contact the leading end is attached by the adhesive to the roller 42 which is in rolling contact with the roller 31, Fig. 20, to transfer the leading end to the trailing end using the other side of the adhesive tab whose bond is stronger than that of the side contacting the roller 42. The splicing apparatus includes a web roll stand 1, Fig. 1, having a pair of front and rear arms 141, 142, respectively which are mounted pivotally and adjustably to accommodate web rolls of different width.

The driving shaft 10 drives the rotary looper-tube 38 through gearing 30-32 and a shaft 33. The gear 31 is journaled on a yoke 34 with a spur-wheel 35, gearing with a pinion 122 on a shaft 87 of the feed-directing mechanism. The needle-carrying tube below the work support is also geared to the lower shaft of the feed-directing mechanism. When the direction of feed is changed, the yoke 34 is rotated about the shaft 10, 33 and the movement of the thread carrier suitably advanced or retarded. A feed-bar is pivoted to sleeve 126 loosely mounted on the tube 38 and lifted periodically by a cam for the return stroke of the feed-bar. The feedbar has an extension 104 in which is rotatably mounted a slotted disc, embracing the squared lower part of a block 117 fixed to a shaft 101. The feed-bar is moved in the direction of the slot by a lever 103 pivoted on the block 117 and actuated by a cam surface upon an axially reciprocating collar 114. The shaft 101 is turned to vary the direction of the feed by usual connection 100, 99, 88 with the feed-directing hand-lever. The collar 114 is actuated by an arm of a camoperated slider.
