Abstract: 1,226,399. UF resin powders treated against agglomeration. KAO SOAP CO. Ltd. 3 Oct., 1968 [4 Oct., 1967], No. 46925/68. Heading C3R. Agglomeration of a powdered urea-formaldehyde (UF) resin is prevented by applying thereto a solution of a non-dissociative water-soluble macromolecular compound and a surface-active agent, in an amount providing 0À005-2À0 wt. per cent of these combined relative to the powder, and drying the powder. The solution preferably contains 0À1-20 wt. per cent of the additives in a weight ratio of surfactant to macromolecular compound of 1:10 to 10:1. Suitable UF resins are (1) acid-condensed UP powders, and (2) moulding compounds obtained by mixing neutral- or alkaline-condensed UF resins in solution with fillers and pigments or dyes, and drying and crushing the mixture. Suitable macromolecular compounds are polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), polyvinyl methylether, poly-N-vinyl-5- methyl-2-oxazolidinone, and soluble partly acetylated or acetalized PVA's, polyvinylacrylamide and methylcellulose (MC). Many suitable surfactants are listed. In Examples 1 and 2 an acid-condensed UF powder is treated with various PVA/sodium dodecyl sulphate (SDS) solutions; in Example 3 a commercial UF moulding powder is treated with solutions in which the PVA is replaced by PVP, MC, Na polyacrylate and partially acetylated or acetalized PVA's (Table 3), and the SDS is replaced by a resin soap, sodium oleate, sodium propylnaphthalenesulphonate, laurylmethylammonium chloride, polyoxyethylene lauryl ether or lauryl betaine.

A method of developing an internal latent image or intensifying a photo-developed image in the sensitive layer of a photo-developable silver halide material and stabilizing the resulting image comprises treating the layer with an aqueous solution in the presence of a photographic silver halide developing agent, a thiocyanate silver halide solvent and a weak silver-complexing agent (i.e. a silver ion complexing agent which inhibits the retarding effect of a stabilization retarding addendum, and which is neither a silver halide reducing agent nor a compound of which the normal or a tantomeric, form contains a mercapto group-the addendum referred to above is one which reduces the rate of dissolution of the silver halide in an aqueous stabilizing or fixing solution). The developing agent may be a 3-pyrazolidone, hydroquinone or an ascorbic acid developing agent. The weak silver-complexing agent may be an organic compound having a double bond, a halogen-substituted hydrocarbon or an organic compound containing at least one S atom having an unshared electron pair in a grouping -C-S-C-, -C-S-O-C-, or -O-CH 2 CH 2 -S- which forms part of an open chain or a ring. The weak silver-complexing agent is preferably an acyclic or cyclic ethylenic compound, an aromatic compound, an unsaturated heterocyclic compound, a halomethane, a dihaloethylene, a halobenzene, a sulphide, a sulphoxide or a sultone and may be an organic thioether silver halide solvent.

Abstract: 1330140 Making interconnection module BUNKER RAMO CORP 9 Nov 1970 53276/70 Headings B3A and B3R [Also in Divisions H1 and H2] An interconnection module for connecting desired points on a printed circuit board comprises a non-conductive core having wire receiving means spaced along its length, wires extending between selected receiving means and terminals each located at one of at least some of the receiving means and electrically connected. to the wires received in that receiving means. Insulated wire 27, Fig. 1, from a drum 26 is wound on to a slotted plastics core 10 under the control of a computer 37 by a stepping motor 36 which positions the wire opposite a desired slot in the core and a motor 21 which intermittently drives the core in 180-degree steps by means of coupling 24. After winding, the core 10 and terminal frames 40, Fig. 6, are clamped together and terminals 42 are dip-soldered to the wires in some of the slots. The wires in other slots are soldered together to provide connections internal to the interconnection module. After soldering, the wires on the top surface of the core are cut or ground off and the terminals are separated by shearing frames along the line 48. The module is finally encapsulated in epoxy resin. The terminals may be bent into flat pack form, Fig. 9 (not shown). In another embodiment, the core is cylindrical with longitudinal and circumferential grooves. The terminals are provided by winding wires 42<SP>1</SP>, Fig. 16, round a spacer 88. The top part of the core cut away or, if a separate metal part, removed. The wires in the slots are then connected by soldering (e.g. using infra-red heating to melt the polyurethane insulation and fuse solder cream) or by setting in conductive epoxy resin. Finally the module is encapsulated in epoxy resin and the spacer is removed. For high speed switching, ground planes may be included between the wires and the core and a conductive case placed over the module. The interconnection module may be used to interconnect integrated circuits on daughter boards which are mounted on a mother board which also carries another interconnection module to interconnect the daughter boards.

Abstract: 1337663 Dough cutting and moulding MASCHINENFABRIK BRIEM - HENGLER & CRONEMEYER KG 4 Aug 1971 36559/71 Heading B5A [Also in Division B4] In an apparatus for cutting out dough shapes, a ribbon of dough 4 passes through two pairs of rollers 7, 22, each pair comprising a cutting roller and a counter pressure roller, the first pair 7 cutting the inner cut-outs and the second pair 22 cutting the outer shape, and the ribbon of dough is carried, e.g. by conveyer 2a and 2b or 3a, round a portion of the circumference of the first cutting roller 7a and on to the second pair of rollers 22 after the removal of the cut-outs. The dough shapes may be removed by a further conveyer 27, the remaining skeleton of the dough ribbon being carried away on conveyer 26. In one embodiment, Fig. 2, the cut-outs are separated from the dough ribbon by blowers 5a and/or 5b which force them through the cavities in cutters 8 into roller 7a. The cavities 8a, 8b and 8c of the cutters diverge inwardly, see Fig. 6, to prevent jamming of the cut-outs, and the cutters have portions 8d for embossing the dough shapes. The cut-outs are removed from inside roller 7a by a curved conveyer belt 6a. A baffle 14 which extends through and beyond the sides of conveyer 6a prevents the cut-outs reaching the inner wall of roller 7a. A single conveyer belt 1 (Fig. 1, not shown) may replace the two parts 2a and 2b, a portion of the belt being diverted around blower 5b. In another embodiment, Fig. 4, a conveyer belt 3a is wetted by a roller 5d<SP>11</SP> so that the cut-outs 4a adhere to it and tend to follow it where it is diverted by rollers 13, 17, 18, 19. A stripper plate 21 removes the cut-outs which drop on to a curved transverse conveyer 6b. The cutters 8 in this case have outwardly diverging cavities (Fig. 7, not shown) so that the cut-outs remain on the conveyer. In a similar embodiment (Fig. 3, not shown) the conveyer belt (3) is not wetted and the cut-outs are separated by a blower (5c) above the dough ribbon which blows the cut-outs down on to conveyer 6b.
