Patent GB-911427-A (GB)
Title: Improvements in or relating to the manufacture of mouldings
IPC: B29C44/56
Filed: 1959-04-09
Abstract: A method of moulding manufacture comprises treating a body of foam-like form such as polyurethane foam with a hard setting resin, forming the treated body to the required shape in a mould, and allowing curing of the resin to take place whilst the body is in the mould.  Dry polyurethane foam, e.g. in strip form 2 or 3 inches wide and 6 feet long, is immersed in a resin, e.g. a polyester, epoxy, or resorcinolformaldehyde resin which may contain an appropriate catalyst and accelerator or hardener, in order to impregnate it with the resin, after which resin in excess of that necessary to wet or coat the interstices of the foam is removed by subjecting the foam to pressure, such as between rollers.  The moulding surface(s) of the mould are first treated with a parting agent such as a suitable wax and, where a smooth non-cellular finish is required to the moulding, a facing coating is also applied.  This may, for example, be the same resin used for impregnating the foam together with a hardener and mineral filler (e.g. French-chalk) with or without a thyxotropic agent and/or a pigment.  The finished mouldings are both light and rigid owing to their porous texture and the fact that the cell walls are coated with the cured resin.  Their impact strength may be improved by incorporating polysulphide polymers in the hard setting resin.  The mould may be coated with the impregnated foam in strip form and laminates may be built up, the strips and/or sheets being joined by means of the impregnating resin.  Metal inserts or reinforcements may be included in the moulding as it is being formed. The manufacture of panels for vehicle bodies, doors, and mudguards is referred to.  The mould itself may be produced by the same method of manufacture, i.e. of impregnated polyurethane foam cured and preferably facing coat finished as above, or else made of a cured mixture of an epoxy resin, a hardener, a filler, and chopped strand glass fibres.

Abstract: 543,892. Optical recording. BRITISH TABULATING MACHINE CO., Ltd. July 34 1940, No. 12115. Convention date, July 25, 1939. [Class 40 (ii)] [Also in Group XL] Data are recorded on statistical cards and the like by code frequency tracks f1 .. f7 in code positions 1 .. 12 in columns a .. g. Some of the frequencies, e.g. f<SP>1</SP> .. f<SP>6</SP> may represent digits, and others, e.g. f<SP>7</SP> may represent, classes. These records may be produced by photographing light modulations by the apparatus shown in Figs. 11-15. Light from a lamp 118, Fig. 11, is projected by an optical system 119 to a mirror galvanometer 122 which reflects the light through an optical system 124 to a film 116 driven by rollers 117. The image of a mask 121, Fig. 12, in the optical system 119 is projected on a slit mask 126, Fig. 13, in the other optical system 124 as shown in Fig. 14, and an oscillating current of the desired frequency is fed at the desired moment to the galvanometer whereby the desired track is impressed on the film 116. One such light modulating device is provided for each column of the record. The several oscillating currents are generated by thermionic oscillators 129, Fig. 15, each connected to its galvanometer through key switches 131, one of which is closed according to the desired code position of the frequency track in its column, and through a rotating distributer 132 synchronized with the moving film to complete the galvanometer circuit at the desired moment. These records are scanned photo-electrically in a machine, Fig. 6, having a double station as in present Hollerith statistical systems. Photo-electric scanning devices 21a are provided at the upper station for sensing the class and supplemental code markings, and other photo-electric scanning devices 21 are provided at the lower station for sensing the code markings representing amount data. At each station, a single lamp 18 is provided together with a single optical system 17, 16 for projecting a narrow beam of light across the record 10 ; and for each column on the record a separate optical system 19 is provided to direct light from the several columns to the several photo-electric cells 21. A single amplifier may be used for the several cells of a station, the output being separated out and fed to separate circuits by means of devices in the output circuit tuned to the respective frequencies. Other parts of the machine and the system are generally in accordance with the present practice of this art. Reference has been directed by the Comptroller to Specification 529,562, [Group XL].
