Title: Improvements in or relating to machines for washing bottles
IPC: B08B9/42
Filed: 1948-12-09
Abstract: 661,123. Bottle washing machines. LARRIEU, H. Dec. 9, 1948 [Dec. 19, 1947], No. 3104/48. Class 138 (i). [Also in Group XXX] In a machine for washing bottles by soaking and jetting with liquids, conveying chains carry bottle carriers each comprising two vanes rigid with the links of the chains, a bottom recess for the bottle neck and two other vanes arranged to be movable with respect to the rigid vanes, so as to leave a free gate therebetween for charging 'and discharging bottles at a charging and discharging station. In one embodiment the bottles are carried by endless parallel chains 1, Fig. 1, through a tank of liquid and past cleaning jets in a known manner, the bottles being loaded into the machine and discharged therefrom by a chain conveyer 10 operating transversely of the endless chains. The bottle carriers Fig. 3 comprise crossbars 3 fixed between the opposite links 2 of the chains 1, which crossbars are,formed with recesses 4 to receive and centre the bottle necks. Opposite each recess and fixed on each side of the crossbar 3 are vanes 5. Between the crossbars 3 there are provided crossbars 7 fixed to the opposite links 6 of the chains. Vanes 8 are fixed to the crossbars 7 at right angles to the vanes 5. On the straight portions of the conveyor 1 the bottles are therefore carried in between the vanes 5 and the vanes 8. However, as will be seen from Fig. 1, when the carriers pass round the driving sprockets 9 the vanes 8 move relative to one another in the manner of; a fan about the driving shaft 13 and thereby provide a gateway through the fixed vanes 5 at a position above the conveyer 10. The motion of the conveyer 10 is arranged to take place during the inoperative periods of the chains 1 and is such that the number of dirty bottles moved into the machine is the same as the number of bottle carriers disposed between the opposite links of the chains 1. When the dirty bottles are in position the chains 1 move through a distance equal to twice the pitch of the chains 1 and the bottles are thereby carried into the machine by the vanes 5. At the same time clean bottles from the following row of racks are deposited in the conveyer 10. When the conveyer 10 again moves the clean bottles are discharged from the machine while at the same time' a further series of dirty bottles is introduced into the machine. In another embodiment the vanes 8 are replaced by vanes secured to hinged bars between the links that carry the recessed crossbars, which vanes are retracted at the loading and unloading position by a retractable hook. The vanes resume their original positions under spring action. In this case the chains 1 would move through a distance equal to only one link pitch which is made twice the pitch of the links in the first embodiment.

Patent GB-786592-A (GB)
Title: Polymeric esters and products containing them
IPC: C08F220/34
Filed: 1955-11-10
Abstract: A polymeric ester comprises an acrylic acid or an alpha-alkacrylic acid polymer substantially completely esterified with amino-alcohol salt residues of which 35 to 75 per cent contain tertiary amino salt groups and 65 to 25 per cent contain quaternary amino salt groups, the anions of the salt residues being of the nonphotographically active type.  Suitable anions are those of sulphuric, methanesulphonic, ethanesulphonic, decanesulphonic, dodecanesulphonic, benzenesulphonic, p-toluenesulphonic, cyclohexanesulphonic, methylsulphuric, phosphoric and perchloric acids.  The copolymers may be obtained by copolymerizing in an aqueous solution having a pH between 6.5 and 7.5 a mixture of an ester containing a tert.-amino alcohol salt group, e.g. diethylaminoethyl methacrylate methylsulphate, and an ester containing a quaternary amino salt group, e.g. methyldiethylmethacryloxyethylammonium methylsulphate, in the presence of a catalyst such as ammonium persulphate, benzoyl peroxide, hydrogen peroxide and azo-bis-isobutyramidine hydrochloride.  Too high a rate of polymerization may be reduced by the addition of an inhibitor, e.g. tert.-butyl catechol or oxygen. The copolymers are used in the preparation of photographic emulsions. Other unsaturated monomeric esters of amino alcohols from which suitable tertiary and quaternary esters may be prepared are described in U.S.A. Specification 2,138,763. Specifications 600,023 and 718,422 also are referred to.

[Also in Division B5] A welding device for making packages from a tube filled with liquid comprises supports 1, 2 movable along horizontal columns 3, 4. Welding dies 8, 9 mounted on rails 6, 7 are rotatable about axes 5 secured to the supports 1, 2. Springs 12 act so that the surfaces of the dies 8, 9 form an acute angle when in the open position (Fig. 1) and are held by pins 13 in slots 14. The tube 15, which is a strip of plastics or coated paper folded longitudinally at 17 and having a welded seam 16, hangs between the dies 8, 9 and extends downwards into a shaping device, Fig. 5 (not shown). In operation, the supports 1, 2 are moved towards each other and the dies 8, 9 compress the tube 15, forming initially a wedgeshaped cross-section, Fig. 2 (not shown). Further closing causes rotation of the dies about their axes 5 turning the seam 16 away from the centre-line of the tube. This action, and the simultaneous increase in pressure in the liquid due to the compression, removes folds from the parts of the tube to be welded. The shaping device, Fig. 5 (not shown), comprises lateral and lower shaping dies (21), (22), movable in coordination with the welding device above. The lateral shaping dies can contact the tube satisfactorily due to the turning away of the seam 16.
