Abstract: 1472181 Colour electro-photography CANON KK 23 April 1974 [24 April 1973] 17680/74 Heading G2H As spaced colour separation latent images are formed on movable photo-conductive member 5 and developed by respective liquid developer applicators 71, 72 and 73, contamination of an image by coloured toner appropriate to a neighbour is avoided by application of a toner-attracting potential to parts of the member 5 between the images. Any liquid developer which runs down the surface of the member 5, and passes outside the limits of its appropriate image, gives up its toner to a non- image area. The non-image areas may be given a charge which is higher than that of any imagebearing area, and be correspondingly effective in attracting toner.

Abstract: 1,172,647. Injection moulding. A. FISCHBACH. 16 April, 1968 [26 April, 1967], No. 17946/68. Heading B5A. Mould parts on fixed and movable platens 6 and 5 respectively are brought to a closed position in two stages, in the first of which the platen 5 is moved forward by hydraulic pistons and cylinders 7a, 7b, 8a, Sb on a stationary wall 2; in the second stage a piston rod 10 fixed to the platen 5 and slidable through a piston 12 in the wall 2 is hydraulically urged forwardly by that piston. In one embodiment the latter carries locking elements 14a, 14b pivoted at 15a, 15b which, during the first stage, are urged out of engagement with the piston rod by hydraulic cylinders 18a, 18b; at the end of this stage the cylinders are de-energized and the locking elements brought into contact with a recessed part of the piston rod by a spring 20, so that when the piston is moved forward the keys abut a shoulder 11a to move the rod and hence the platen 5 to a final mould closing position. In a modification the piston carries a pair of radially slidable locking elements which engage a recessed part of the piston rod, and are actuated by a rotary plate carried by the piston and which has cam slots engaging pins on the elements.

Title: Improvements in or relating to embossing machines
IPC: B29C65/18
Filed: 1939-06-20
Abstract: 530,846. Embossing. RAYMER, M. M., and POOLE, R. S. June 20, 1939, No. 17996. Convention date, Jan. 19. [Class 100 (ii)] [Also in Groups XVII and XXII] Paper sheets are embossed by passing between movable, opposed embossing elements, and correct operation is ensured by adjusting the relative positions of the elements in their direction of travel. The invention is applicable to the sealing of open bags and like containers as described in Specification 530,845, [Group XVII], and the embodiment described relates to the sealing of a waxed liner of a carton by embossing in order to prevent separation in any subsequent operation. The waxed liner 5, Fig. 3, is presented to a pair of heated sealing irons 6 capable of movement towards each other, and also of longitudinal movement in the direction of travel of the liner. The brackets 8 carrying the irons are mounted on carriages 9 adapted to slide on rods 10. The rods 10 are mounted on lugs 11 on a base plate 12 adapted to slide transversely on rods 23. The sealing irons are caused to approach and close the liner and to travel with it to the embossing station. The closed and heated part of the liner then passes between chains 36, Figs. 10, 11, comprising multi-sectioned links 39 held together by pintles 40. The arrangement of the chains and the shape of the links are such that the links of one chain register with depressions between the links of the opposed chain. Indentations are thus formed to provide an interlocking closure of the liner and to ensure continued adhesion during the final operation of folding and tucking. The chains are pressed together by spring mounted plates engaging the inner surfaces of the opposed runs, and blasts of cold air are directed on to the chains to cause the wax to set. An adjustable carriage carries the sprockets at one end of the chains so that the tension may be maintained. Relative displacement of the opposed embossing surfaces is liable to cause the results shown in Fig. 13, where the plates 66, 67 are out of alignment, such as pinching or cutting the shoulder 70, and insufficient action at 69. In order to adjust one plate longitudinally in respect of the other, the shaft 59, Fig. 10, carrying one of the sprockets is connected to its gear wheel 64 by means of a collar 72, keyed at 73, carrying lugs 74 having screws 75 engaging a lug 76 on the gear wheel 64. Instead of using the links of the chains' as the embossing surfaces, the chains may be slightly spaced apart and may carry plates as shown in Fig. 11, articulated so as to accompany the chains round the sprockets, and carrying designs such as letters, oblique lines, crosses &c.

Title: Reaction products of polymers with polyisocyanates or polyisothiocyanates
Inventor: JONES FREDERICK ARTHUR
IPC: C08G18/10
Filed: 1954-06-21
Abstract: Synthetic elastomers are prepared from a reaction product of a polyester, polyether or polyesteramide and a polyisocyanate or polyisothiocyanate in admixture with an acid ester of a phosphoric acid by neutralizing the acid ester which retards setting of the reaction product and then moulding the mixture. The stabilized mixtures retain the capacity for being milled to form sheets for long periods.  Pre ferred esters are the mono- and di-alkyl esters of orthophosphoric acid, the alkyl groups of which contain 2-18 carbon atoms.  Polyisocyanate may be reacted with polyester in two stages-one before addition of the acid ester and the other before its neutralization.  If desired an organic acid chloride may be added to the reaction mixture as described in Specification 790,543. Preferably the acid phosphate is added to the hot reaction product and the acid chloride added by subsequent cold milling.  Suitable bases for neutralizing the acid phosphates are diphenylamine, p-phenylenediamine, diphenylguanidine, guanidine, aniline, piperidine, benzylidene, dipiperidine, aminopyridine, 2,2 - dipyridylamine, 2 - amino - 4,6-dimethylpyridine, urea, hexamethylene tetramine, hydrazine hydrate, magnesium oxide, calcium hydroxide, and ammonium carbonate.  In the Examples: (1) hot dehydrated polyethylene glycol wax mixed with naphthalene-1.5-diisocyanate followed by 1.4-butylene glycol as a cross-linking agent.  Butyl acid phosphate was added.  The mixture was heated, milled and divided into four parts which were milled to give sheets after various periods of storage, the sheets being moulded after neutralization of the acid phosphate with diphenylamine; (2) is similar to (1) but the cross-linking agent was added as an amine or mixture of amines in excess of the amount required to neutralize the butyl acid phosphate; (3) is also similar but employs a mixture of mono-ethyl and di-ethyl hydrogen phosphates; (4), (5) and (6) are similar to (2) but illustrate the addition of p-nitro-benzoyl chloride as well as butyl acid phosphate.
