Filed: 1928-12-10
Abstract: 302,577. Henkes, A. Dec. 17, 1927, [Convention date]. Plant for relaying track.-Tracks are relaid in a continuous forward operation by taking up and, carrying the old track complete, by excavating, cleaning and replacing the old ballast, and then bringing up and laying complete track sections, the tracks and vehicles being carried by detachable wheels on the existing track or on an auxiliary track laid at the excavated site. The rails are welded together and secured to sleepers, in a station yard, to make a track section up to 200 feet long. The track sections are then carried on the main tracks by rollers 11, Fig. 7, clamped to the rails, and on the auxiliary tracks 4, Fig. 15, by brackets 3' clamped to the sleepers 7 by longitudinal or transverse wedges 12. To adapt the brackets for wood or iron sleepers, the brackets 2, Fig. 8, have a jaw 5 engaging the rail 6 and a support 8 is inserted in the aperture 9 or 10 after the track has been raised by jacks 1. The jacks may be dispensed with by using brackets 16, Fig. 13, having a screw 17 and nut 18 for a support 8, the bracket being held while lifting or lowering the track by a prop 19. In an alternative arrangement Fig. 17, the sleeper is secured by a wedge 22 and pivoted cramps 23 in a sleeve 21 actuated by a screw 26 and guided on an upright 25 carrying the roller 3. 'The excavator wagon Fig. 19, may run on the road bed on endless tracks, and carries an excavator 40, ballast screen 41, and conveyer belts 42, 43 for dirt and cleaned ballast, the ballast tube being suspended from an overhead conveyer 34. The ballast is then rolled by a machine 45. The ballast wagons are carried over the auxiliary track 4 by attaching brackets 14, Fig. 10, which may be adjusted in height to run on the rails 4 laid on the new ballast. The entire train may be propelled by a locomotive or by a special engine supplying power for driving the machines and jacks and electric winches.

Patent GB-764022-A (GB)
Title: Process for the production of highly voluminous condensed alkali phosphates
IPC: C01B25/39
Filed: 1954-12-30
Abstract: A solution comprising an alkali metal phosphate glass such as Graham salt (soluble sodium hexametaphosphate) is sprayed into a zone containing a gas such as air, at 130-600 DEG C., preferably 160-400 DEG C. and the so-formed calcine removed from said zone, and where necessary heated at below sintering or fusion temperature, whereby highly voluminous condensed alkali metal phosphates having bulk weights from below 5 to over 60 grams per 100 ccs. and a very high rate of solution, are obtained.  Mechanical damage to the material, which is generally in the form of small agglomerated hollow bodies of particle size 5-300 m , (such as would be produced in a cyclone separator or in sharply bent conduits), is avoided, e.g. by collection in the lower part of the spray chamber or in a stabilizing chamber following directly thereafter: the subsequent heat treatment may be perforated in a rotary tube.  An alkali metal orthophosphate, e.g. NaH2PO4 and/or Na2HPO4 and/or K2HPO4, may also be present in the solution, if desired, as the major constituent, e.g. so as to replace 80-90 per cent of the phosphate glass: in this case the product of the spraying is generally subsequently heated to convert is to pyro- or tripoly-phosphate &c.  Acidneutral- and alkaline-reaction glasses and a starting solution of an acid or neutral glass to which alkali metal carbonate or hydroxide is added, to give an Me2O: P2O5 molar ratio of 1-2:1, (Me being an alkali metal) are referred to and exemplified and the products resulting from their calcination (which generally correspond roughly in composition and acidity to the initial compound) described: the Me2O:P2O5 molar ratio may be 0.7-2:1, preferably 0.95-1.5:1.  The product may comprise pyro-, tripoly-, polymeta- and high molecular weight polyphosphates: some orthophosphate may also be present: sodium tripolyphosphate may be obtained by spraying a solution of a phosphate glass to which caustic soda has been added to give a Na2O:P2O5 ratio of 5:3 at high temperature, or by using sodium carbonate and thermally treating the product at 250-400 DEG C.  The glasses are preferably prepared as melts in a rotary kiln from alkali metal carbonate and P2O5 vapour, utilizing the heat of combustion of phosphorus or by melting a mixture of mono- and di-sodium orthophosphate.  The concentration of the phosphate solution is preferably as high as possible, and in some cases (e.g. Na2HPO4.12H2O) a solution may be prepared by heating a salt which thus dissolves in its own water of crystallization.  Other solutions may have concentrations of 50 per cent by weight or more although concentrations as low as 25/100 ccs. can be successfully used.  In general the solutions should be prepared and stored at room temperature to avoid hydrolysis, but if desired some hydrolysis to tripoly- and pyro-phosphate may be promoted by allowing a hot and preferably alkaline solution to stand for e.g. an hour at 80 DEG C. Specification 744,576 is referred to.

Title: Improvements in four yarn overplaid knitting machine
IPC: D04B9/28
Filed: 1958-11-24
Abstract: 903,479. Knitting. LEVIN, N. Nov. 24, 1958 [Dec. 9, 1957], No. 37763/58. Class 74 (2). A machine has a circle of needles which can be reciprocated to knit body fabric at a plurality of circumferentially - spaced feeds to form a pair of body fabric diamonds having common wales and suture joined edges and means to selectively feed a design yarn, during the reciprocation, to permit the group of needles forming the common wales to draw loops of that yarn, independently of the body fabric knitting, to form a line of stitches of design yarn in the common wales and extending uninterruptedly across the suture joined edges of the diamonds, to provide an overplaid in both diamonds. At each of the feeds 1-4 are provided selectively-operated body yarn fingers 54; and between the feeds are overplaid yarn fingers 35-38, each of which can be swung to supply yarn at either of the adjacent feeds. The fingers 35, 37 are linked by a rod 50 and the fingers 36, 38 by a rod 49; thus the members of each pair move in unison. Body yarns may be supplied to selected needles by selected ones of fingers 54 at feeds 1 and 3, or at feeds 2 and 4, to form a pair of the diamonds 20-24 of a sock or the like, whilst all the fingers 54 at the other two feeds are raised to inoperative positions, the pairs 35, 37 and 36, 38 of overplaid fingers being swung in alternation across the needle circle, to supply yarn at these other feeds to selected needles to form overplaids 31-34. The pairs of overplaid fingers are swung into and out of feeding position, relative to feeds 1 and 3, by a cam 65 and, relative to feeds 2 and 4, by a cam 64. The cams are borne on a shaft 66 which rotates once for every four rotations or for every complete forward and reverse movement of the needle cylinder, and they act through rollers 63, bell-cranks 59, 60 and link and lever systems. The rollers 63 are moved from a neutral position, into the path of either cam, by the combined action of a spring 93 and cams 90, 91 on the main pattern control drum 92. Such movement of the rollers into an active position, flexes flat springs 78, 79, which serve as return-springs. Each of the four overplaid yarns 31-34 extends in a zig-zag line of which the straight runs extend across sutures 30 and between centres of adjacent diamonds thus, for example, yarn 31 runs between the centres of diamonds 24, 22, 25, 23 and 26. Specification 790,141 is referred to.
