The track 1 comprises two channel members 9, 10, providing guides for wheels 31 and a channel 1b in which is mounted blocks of nylon 15 having slots 16, 17 accommodating drive member 2. At bends 13, Fig. 1, the top flange 9a of member 9 is cut away and the member 10 is omitted to accommodate the periphery of drums 3, 4, around which pass the member 2, flange 10a of member 10 being replaced by fixed segments 14; the drum 3 is reciprocally driven through members 22, 24, 25 from a power unit 5 to reciprocably drive member 2. An endless member 2 may travel in the same direction all the time. The member 2 is in the form of a strip, or rigidly or pivotally connected strips, with abutments on the upper edge which engage a plate 34 pivotally carried by a channel member 33 pivoted to the front axle 29 of the carrier 6 to propel the carrier. The plate 34 is biased by springs 38 and cross-pin 36 in slots 37 in member 33 to a position in which it is engaged by the drive member 2. The plate 34 rotates freely on reverse movement of member 2 and the springs 38 are overcome by member 2 should the carrier 6 be arrested to avoid damage. The front part 33d of member 33 is shaped so that it can be depressed on striking a stop or the end 28c of a preceding carrier to disconnect plate 34 from drive member 2 to bring the carrier to rest. In section 19 which the carrier traverses more slowly, for example, than the rest of the track a second drive member 20 is mounted in slots 17, Fig. 4, at a higher position than member 2 to engage the plate 34, as described in Specification 1,044,837. Member 2 may comprise separate parts pivoted together and be provided with wheels, Figs. 5, 6 (not shown). Different parts of member 2 can be separately driven at different speeds.

Abstract: 1,125,356. Position encoders. COMMISSARIAT A L'ENERGIE ATOMIQUE. 15 May, 1967 [16 May, 1966], No. 22483/67. Heading G4H. A system for the remote position indication of a moving element e.g. an element of a nuclearreactor re-charging system includes a member having coded parallel tracks e.g. as in Fig. 2, the member being driven in synchronism with the element between a fixed light source and a photo-electric detector, a selector, e.g. a disc as in Fig. 3, uncovering the tracks in succession so that the output from the detector is a plurality of markings serially transmitted. The selector and coded member each have a supplementary track with markings which, when they coincide allow light to pass to a further photo-electric detector to enable the output from the first detector to be read. In the embodiment described, both the angular position of a bridge 12 (Fig. 1) and the linear position of a carriage 14 on the bridge 12 are read by means of binary coded members sensed by photo-oells as selectors rotate. The output from photo-cell 26 representing the angular position of the bridge is fed to a store 52 which controls a display system 54 and if it is required to position the bridge in accordance with a position entered via a keyboard 60, the output from the store and keyboard are fed to a comparator 62 the output from which stops the motor driving the bridge when coincidence is reached. The carriage may be similarly positioned. The coded member for the carriage is an endless belt having parallel longitudinal tracks, a selector disc scanning the tracks sequentially. The selector disc may be replaced by a drum.

Preferably, the composition has pH not above 6. There may be mixed with the liquid composition fillers, e.g. 0À4-9 p.b.w. per 100 of composition of a metal powder, for paints, or 3-12 p.b.w. per 100 of a refractory powder, for foundry shell moulds, and with the latter 4 p.b.w. of ZnCl 2  and/or 0À05-3 p.b.w. of hydroxypropyl-cellulose. The polysilicate (1) may be prepared by heating an alkyl orthosilicate or polysilicate, e.g. (EtO) 4 Si, with the ethylene glycol monoether at pH 1À4-3À5 or by reaction of SiCl 4  with the glycol ether, and hydrolysis of the product to the required extent. C 1-4  alkyl silicates and organic solvents are then added, if necessary, to give the desired compositions. In Example 1 ethyl silicate 40 is heated with 2- ethoxyethanol and water equivalent to 55% hydrolysis, water equivalent to hydrolysis up to 75% and a little HCl is then added to give a stable liquid. A paint is obtained by adding water and ethoxyethanol to a theoretical hydrolysis of 85-110% and SiO 2  content 7-17À3 wt. per cent, then Zn dust (25 p.b.w. per 9 of binder) and 2 wt. per cent of bentonite and 5 wt. per cent of talc. The paint is applicable to steel, cast iron, galvanized steel, glass, Al, Cu and tinned steel. A similar binder is obtained starting from SiCl 4 . In Examples 2-3 a similar binder solution is mixed with silica flour in 1 : 4 weight ratio, or with zircon flour and silica flour (1 : 3 : 1), or with two grades of silica flour after thinning with isopropanol, to give slurries for preparing shell moulds by the stucco process. In Examples 4-5 moulds are cast from a 1 : 5 : 1 mixture of binder, zircon flour and silica flour in which the binder contains 10% aqueous NH 3  and 90% 53% hydrolysed ethoxyethyl silicate.
