Title: Art of compounding rubber
IPC: C08K9/08
Filed: 1934-12-18
Abstract: Compounding agents such as pigments, dyes, vulcanizing agents or accelerators, or anti-oxidants, are incorporated in finely divided form with water-dispersed rubber such as rubber latex, the dispersion flocculated to produce rubber flocs in which the agent is embedded, and the flocs de-watered to give crumbly cake with a water content of 25-45 per cent, which is mechanically powdered, dried, and added to a rubber batch being milled, whereby the compounding agent is dispersed throughout the batch.  The powdered rubber containing compounding agent is prepared as disclosed in Specification 449,255, for example, by adding an aqueous suspension of Victoria Blue to the latex casein solution described therein, flocculating with zinc chloride de-watering, comminuting, and drying.  Specifications 338,975 and 327,451 [both in Class 70], also are referred to.  The Specification as open to inspection under Sect. 91 includes the preparation of the rubber powder by processes other than that described in Specification 449,255.  Thus the compounded latex may be sprayed on to a hot moving surface and the particles scraped therefrom.  This subject-matter does not appear in the Specification as accepted.
Patent GB-792631-A (GB)
Title: Improvements relating to the manufacture of laminated plastic sheets or articles
IPC: B32B15/08
Filed: 1955-12-19
Abstract: A heat conducting plastic article is made by forming a sheet of plastic material, depositing on it a coating of finely divided metal consisting of particles touching each other with intersticial spaces between them, and thereafter treating the coated plastic material to cause the synthetic resin to flow into the intersticial spaces and then to set, usually by polymerizing the resin under pressure at a suitable temperature.  The coating is deposited on at least one of the laminae after it has been formed to shape and the laminae are stacked together with the coating, or each coating, interposed between two laminae.  The finely divided metal coating may be applied by spraying the metal in a pulverized state, by spraying in a molten state (the droplets fusing together at spots thus forming a resisting but permeable layer), or from suspension in a volatile medium consistent with the resins used.  A laminated article may be built up by coating a plastic sheet with a layer of metal powder, coating the latter with another layer of resin, and then baking the whole assembly between press platens.  Preferably the metal is aluminium. In an example, long fibred pipe paper sheets are impregnated with a binder of phenolformaldehyde resin previously unified and added with the usual catalyzing materials.  The sheets are dried individually and metallized with molten aluminium sprayed on whereafter the metallized sheets are stacked and fused together by heat at the polymerizing temperature, under pressure. The paper sheets may be impregnated with a colourless (e.g. an aminoplastic) resin adapted to display by transparency a decoration previously printed or obtained by partial metallizing of the sheets.  Only certain layers may be metallized, or layers of any vegetable or fibrous material (e.g. horse-hair, wool, cotton, flax or various woods or synthetic organic fibres such as polyamides, cellulose acetate or other cellulose derivatives or mineral fibres such as glass or asbestos) may replace the paper sheets.

Title: Method and apparatus for inspecting plated-through printed circuit board holes
IPC: G01N21/956
Filed: 1972-08-04
Abstract: 1351434 Checking printed circuit boards photo-electrically BURROUGHS CORP 4 Aug 1972 [19 Aug 1971] 36505/72 Heading G1A Defects in the electrically conductive coatings on hole walls in a light-conductive printed circuit board are detected visually or photoelectrically. Light from source 15, Fig. 4, passes via translucent surface 17 and into the translucent or transparent board via light transmissive parts of template 59, being blocked from direct transmission through holes 51-55 by opaque dots 61-65. If the coating on the walls of holes 51-55 is perfect no light will emerge on the other side of the board since opaque template 85 overlies the board. However, small holes in the coating such as at 57 allow light to pass out through the holes 51-55 themselves and transparent parts 87-91 of overlying template 85, to be viewed by eye or by a sensor 80 which can scan sections or individual holes in sequence. A typical box for optical inspection is illustrated in Fig. 1 (not shown). Other modifications in which a sensor is used are described in Fig.3 (not shown), the top template is absent, the difference between the diffused light emerging from the board and the more concentrated light emerging from a hole if a defect is present is such that a detector will be able to differentiate between them. In Figs. 5, 6 (not shown) light is passed into the board from its sides, baffles preventing direct illumination of the sensor. In Fig. 1, the templates of the Fig.4 arrangement are transposed.

Title: Process for the manufacture of pure rubber hydrocarbons
IPC: C08C1/08
Filed: 1930-12-08
Abstract: In the process for making pure rubber hydrocarbons by treating latex with alkali lyes at an elevated temperature and producing a cream, the stability of the latex is increased by incorporating water soluble emulsifying agents with it.  The process is preferably carried out in a vacuum or an inert atmosphere.  In an example, 1000 parts of ammoniacal latex are diluted with twice the quantity of water and 1000 parts of 8 per cent caustic soda lye added.  5 to 10 parts of 10 per cent sodium oleate solution is then admixed.  The emulsion is stirred at about 50 DEG  C. for two days and on cooling a creamy emulsion is formed.  After withdrawing the lower layer, the same quantities of lye, water, and stabilizing agent are added and the process repeated a few times.  The cream is then diluted with water and dialysed until neutral.  By coagulation of the latex, a very pure rubber is obtained.
