Patent GB-1014794-A (GB)
Title: An electromagnetic relay in a rectifier comparator circuit
IPC: H01H47/22
Filed: 1964-03-10
Abstract: 1,014,794. Electric protective systems. BROWN, BOVERI & CO. Ltd. March 10, 1964 [March 12, 1963], No. 10009/64. Heading H2K. A relay 3, connected in a rectifier comparator circuit 1, 2 has the contact pressure of its contact set 4 momentarily increased, when it closes, by an R-C network 6, 7 which is supplied from a D.C. source PN. When the relay 3 operates, contacts 4 close completing a circuit from P to N through R.C. network 6, 7 and the winding of relay 3. Thus the winding receives an additional pulse which increases the contact pressure. The magnitude of the pulse is controlled by variable resistor 6. A resistor 9 shunting the capacitor 7 may be provided so that after the initial pulse a small current flows from the source PN and augments the energizing current from the comparator circuit. A rectifier 8 blocks the reactive pulse generated when contact set 4 opens and prevents the current from rectifier 1 from flowing through the R-C network. A relay 5 connected to the source PN is operated when contacts 4 close and actuates a contactor and/or controls warning signals.
Patent GB-364962-A (GB)
Title: Improvements in and relating to the casting of stereotype plates and the like
IPC: B41D3/00
Filed: 1931-04-07
Abstract: 364,962. Printing-surfaces. MASCHINENFABRIK WINKLER FALLERT & CO., AKT.-GES., 35, Wylerring- strasse, Berne, Switzerland. April 7, 1931, No. 10229. Convention date, April 19, 1930. [Class 100 (ii).] In machines for casting stereotype plates or for backing electrotypes of the kind in which the mould d communicates directly with the contents of the pot and the flow of metal is controlled by a valve as described in Speoincationll2,375, [Class 100 (ii), Printing processes &c.], the metal flows into the mould under the pressure of part only of the head of metal in the pot, in order to prevent the forma-. tion of rough edges on the casting and the damage of the matrix. When the mould is filled the full head of metal in the pot may be allowed to act on the casting to prevent the formation of hollow spaces in the plate. The pot a, Fig. 1, may be formed with a small chamber c at the bottom, the chamber being in communication with the pot when the valve d is in normal closed position. In opening the valve d to fill the mould b, the metal drains from the chamber c. Air-escape holes e may be formed at various points in the upper wall of the chamber c to facilitate filling. In a modification the valve d is so arranged that in one position the pot and chamber c are in communication; in a second position, the metal flows from the chamber c into the mould, and in a third position the pot communicates through the chamber c with the mould b so that the full pressure of the metal in the pot can be applied to the solidifying plate. In a further modification, the chamber c is formed over the valve d, and the only communication between the pot and the chamber c is through holes in the top of the chamber. When the valve is opened, the contents of the chamber flow into the mould, and the chamber is refilled through the holes in order to apply full pressure to the casting. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which the chamber is dispensed with, and in filling the mould the valve is only partially opened through a byepass of small cross section, the valve being finally opened to its full extent. This subject-matter does not appear in the Specification as accepted.

Title: Adhesive lacquer an adhesion process employing this lacquer and products obtained thereby
IPC: C09D133/06
Filed: 1974-03-07
Abstract: 1451271 Coated products SOLVAY & CIE 7 March 1974 [8 March 1973] 10246/77 Heading B2E [Also in Division C3] Adhesive lacquers suitable for adhering a thermoplastic resin substrate to a thermosetting resin substrate comprise a polymer containing at least 50 mol % of acrylate or methacrylate ester units, tetrahydrofuran, and at least one amide or sulphoxide solvent. Typical amide and sulphoxide solvents include dimethylformamide, methylformamide, diethylformamide, ethylformamide, dimethylacetamide, dimethylpropionamide, dimethylsulphoxide and diethylsulphoxide. A chlorinated hydrocarbon (e.g. chloroform or methylene chloride), a ketone (e.g. methyl ethyl ketone, diethyl ketone or methyl isobutyl ketone), or an alkyl ester (e.g. ethyl acetate or amyl acetate) may additionally be included in the lacquer as a diluent; such diluent increases resistance of the adhesive to delamination. Specified as the (meth)acrylate polymer are polymetyl methacrylate, polymethyl acrylate and methylacrylate-methyl methacrylate copolymers. The lacquer may also include a vinyl chloride polymer, e.g. a vinyl chloride-vinyl acetate copolymer; this improves the impact strength of products bonded with the adhesive.  In bonding applications, a layer of the adhesive lacquer is applied to a thermoplastic polymer article, e.g. formed from a vinyl chloride polymer, polystyrene or ABS copolymer, then a thermosetting material, e.g. an unsaturated polyester resin, is applied over the adhesive layer and subsequently cured. In Examples the adhesive is applied to a polyvinyl chloride sheet and then an unsaturated polyester resin reinforced with glass fibres is sprayed as a layer over the adhesive layer and cured. The bonding process can be utilised in the production of artcles such as boat hulls, door-frame components, panels and roofing components.

Title: Galactomannan gum solutions and process
IPC: C08B37/14
Filed: 1958-03-31
Abstract: The degradation of colloidal aqueous solutions of galactomannans at elevated temperatures and at a pH above about 5.5, is retarded by adding to such solutions a salt selected from water-soluble metal sulphites, thiosulphates and arsenites. Examples of suitable salts include sodium sulphite, zinc sulphite, sodium thiosulphate and sodium arsenite.  In some instances it is necessary to add sodium chloride to render the selected salt effective or to increase its effectiveness.  Other salts which provide an additive effect, although useless alone, are disodium phosphate, trisodium phosphate and sodium tripolyphosphate.  The galactomannans used include guar gum, locust bean gum and tara gum.  The minimum concentrations of the salts which are required to provide stability are 5% for sodium thiosulphate, 2.5% for sodium sulphite and 10% for zinc sulphite.
