Title: Improvements in or relating to devices for moving or controlling the movement of rail wagons and the like
Inventor: GROSSMITH GEORGE WIL RED
IPC: B61J1/12
Filed: 1951-09-18
Abstract: 714,598. Vehicle movers. STRACHAN & HENSHAW, Ltd. Sept. 10, 1952 [Sept. 18, 1951; Oct. 23, 1951], Nos. 21905/51 and 24785/51. Class 79(1) [Also in Groups XXX, XXXII and XXXIV] A device for moving or controlling the movement, for example down an incline, of rail wagons and the like, comprises a vehicle adapted to run on a track disposed between the usual track rails for a rail wagon or the like, and one or more retractable wheels or rollers mounted on the vehicle and adapted to be projected and retracted laterally so as, when projected, to engage a wagon wheel when the vehicle is caused, or the wagon wheel allowed, to move on its track, means being provided to propel or haul the vehicle on its track such that projection of the wheels or rollers is effected when the vehicle is propelled or hauled in one direction and retraction is effected when the vehicle is propelled or hauled in the opposite direction. As shown in Figs. 1 and 3, a low vehicle 11 which will pass below the axle 16 of a wagon 15, is provided with skids 12 at each side for sliding on track rails 13 disposed between the usual track rails 14 for the wagon 15. The vehicle 11 has a slidable draw bar 18 secured by shackle means 21 to an endless chain 22 which runs under the vehicle to chain pulleys. The movement of the draw bar relative to the vehicle 11 is limited by stops 26, 27 on the draw bar and guides 19, 28 on the vehicle, and a latch mechanism 42' is provided to lock the draw bar to the vehicle in its extreme relative positions. The draw bar carries a pair of pivotally-mounted yokes 29 connected by toothed rack bars 31 which mesh with quadrants 33 pivotally mounted in the vehicle 11. Arms 35 projecting from the quadrants have roller assemblies 36 mounted on their outer ends. When the chain 22 is pulled forwardly the quadrants move angularly so that the roller assemblies 36 project through orifices 37 from the sides of the vehicle. When the chain is pulled rearwardly the roller assemblies are withdrawn so that the arms 35 lie longitudinally of the vehicle. Each roller assembly comprises three rollers 38, 39, 40 freely rotatable on their axes and when the assembly is projected the rollers 38. 39 run on the top of the track rails 14 and the roller 40 is in position to engage the tread of the wagon wheel 41, on further hauling on the chain 22. The rollers apply equal pressure to the wheel treads on both sides of the rail wagon, even though the wagon is being propelled around a curved track and this is due to the arrangement of the yokes, rack bars and quadrants. In a further arrangement shown in Fig. 7 the draw bar 18 has a toothed rack 52 on each side, the racks engaging pinions 54 carried by a yoke 53 which is pivotally connected at 55 to the vehicle 11. The pinions 54 are engaged by the quadrants 33 of the roller assemblies 36.

Title: Purification of cellulose derivatives
IPC: D01F2/28
Filed: 1930-07-21
Abstract: Cellulose carboxylates.-Objectionable constituents are removed from cellulose derivatives, particularly organic esters such as the acetate, formate, propionate and butyrate, by grinding the derivative and removing the finer particles, which contain the bulk of the impurities, by sifting.  The coarser particles give clear solutions particularly suitable for photographic films, filaments, yarns, and clear lacquers and dopes.  Photographic films so prepared do not develop spots.  The finer particles may be utilized for the manufacture of pigmented lacquers, celluloid, and moulding powders. The derivative is ground until it passes through a screen having 5 meshes to the inch and the finer material is separated by a screen of 30-60 mesh, preferably 40 mesh.  A 6-10 mesh screen yields coarse particles substantially free from impurities.  The material may be graded, e.g. by screens of 6, 10, 20, 40, 80, 100, and 200 mesh.

Patent GB-814238-A (GB)
Title: Process for the preparation of acrylonitrile
Filed: 1957-07-11
Abstract: A process for the simultaneous production of acrylonitrile, monovinyl acetylene and acetaldehyde comprises introducing acetylene and HCN under a pressure of substantially 1-4 atmospheres absolute and at substantially 70-110 DEG  C. into an aqueous solution of cuprous chloride containing hydrochloric acid, and ammonium chloride, sodium chloride, and/or potassium chloride, the quantity of HCN used being substantially 50-103 per cent of that quantity which would be converted into acrylonitrile when employing a large excess (more than 103 per cent) of HCN under corresponding reaction conditions.  By operating in this manner, the acetaldehyde formed is not significantly converted into lactic acid nitrile by excess HCN, and may be recovered as such.  The acetylene partial pressure is preferably 1-3.5 atmospheres, and the preferred temperature 80-90 DEG C.  In a preferred embodiment, acetylene at 1.5 atmospheres pressure and 80 DEG  C. is passed into an aqueous solution containing hydrochloric acid and 680 grams of CuCl per litre and 515 grams of KCl per litre, simultaneously introducing 3.8-7.8 grams of HCN per hour per litre of solution. The ratio of acrylonitrile to monovinyl acetylene produced may be increased by: (i) increasing the quantity of HCN (within the above limits); (ii) by decreasing the acetylene partial pressure; and/or (iii) by increasing, within the limits of 1 : 1 to 1 : 0.8, the mol. proportion of CuCl to the additional chloride.  By-products obtained include lactic acid nitrile, cyanbutadiene, divinyl acetylene, higher acetylene polymers, and chloroprene.

Abstract: 671,907. Floor washing machines. LASTOVKA, M. Sept. 7,1950, No. 22099/50. Class 138 (i). A floor-scrubbing machine comprises a liquid reservoir and floor-spraying nozzle, one or more brushes, a water-collecting channel which rests on the floor by means of sealing members, the channel or sealing members together with the brushes defining a water-space, the channel being mounted for vertical displacement and containing an exhaust tube which is connected through a filter to a pump, the pump discharging the filtered liquid back into the reservoir. As shown in Fig. 1, the frame 1 carries a liquid reservoir 5 and spraying device 6. The brushes 2, 3 are driven in opposite directions to confine the water between them. Between the brushes is a trough 10 which collects water flung off of the brushes, the trough being carried by a pair of end plates 21, Fig. 2, mounted for free vertical movement by projections 22 working in guideways 23. Sealing strips 25 extend along the bottom edge of each end plate 21 which, together with the brushes, define a rectangular water space on the floor. The trough assembly rests on the floor by means of the sealing strips 25, and moves vertically to accommodate any irregularities in the floor surface. The sealing strips 25 may be adjustable in thickness and may be mounted so as to be readily replaceable by strips of different thickness, e.g. by making them a sliding fit in dovetail grooves 26. Dirty liquid is sucked from the trough by exhaust tube 11, preferably of flexible material with a longitudinal slot along its lower surface whereby it may be held in position by pressing it on to knobs 32 fixed to the trough 10. A flexible hose 12 connects the exhaust tube 11 to filter 15, water passing through pump 16 and being discharged into a shallow perforated trough 17. A suitable filter is shown in Fig. 11 and comprises three separate cells having coarse, medium and fine guage filters 76, 77 and 78 through which the liquid passes in turn. The invention may be applied to machines having other arrangements of brushes, e.g. Fig. 5 shows a single cylindrical brush 40 with trough 10 and side sealing mem-  bers 41; Fig. 6 shows three disc brushes 50, 51, 52 with a V-shaped trough 10 working on vertical guides 54, and a sealing member 53; Fig. 8, shows a single disc brush 61 with an annular trough 10 and sealing member 65 attached directly to the trough, the trough having vertical guide members 62.
