Title: Curved rigid printed circuit boards
IPC: H05K3/06
Filed: 1975-01-18
Abstract: 1475031 Printed circuits MARCONI CO Ltd 13 Jan 1976 [18 Jan 1975] 2264/75 Heading H1R A curved rigid printed circuit board is fabricated from plural flexible sheets 1 of part cured GRP positioned between laminae 2, 3 having copper foils 4, 5 on the outer surfaces, on which release films 6 of PVF are provided. A further sheet 7 of compressible material is placed on each side of the assembly which is then compressed at elevated temperature (Fig. 2 not shown) between a solid metal cylinder and an arcuate between metal end shims, so as to cure the GRP in curved form. Thereafter the unitary bonded lamina in the press is water cooled and removed. Registration holes are drilled in the curved lamina, whose inner surface is coated with a dyed positive or negative photoresist which is exposed to uv light through a photomask retained in position on the board by an enclosing transparent vacuum bag. Thereafter the mask is removed and the photoresist developed to impose a pattern, using which connecting through holes are drilled. After removal of the photoresist the board and the holes are electroless plated with copper followed by electroplating with more copper. Further positive working photoresist is coated on both faces of the board, and photomasks are applied and retained as before for exposure. The photoresist is developed, the unprotected regions are etched out by e.g. chromic acid, and the remaining photoresist is removed to leave a finished printed circuit board. Alternatively a negative working photoresist may be used with positive masks. After drilling the registration and through holes the entire board is electrolessly coated with copper together with the holes and reinforced with electroplated copper. The photoresist is applied, illuminated and developed to expose the required regions of copper, which are again electroplated with copper and lead tin alloy using the remaining photoresist as a mask. The latter and its underlying copper are removed using the lead-tin layer as an etch resist. Inner layers with appropriate printed circuits may be inserted between the two outer laminae before curving and curing using the registration holes for location, after which the outer printed circuits are formed. The board may be formed into more complex curves.

Title: Improvements in electric insulators
IPC: H01B1/00
Filed: 1943-02-15
Abstract: An electrically conductive coating or composition comprises ceramic material which has been mixed with oxides and subjected to heat treatment to produce within the ceramic material a continuous conductive network of crystals consisting of a solid solution of substances, usually spinels, of different resistivities.  The oxide mixture may consist of zinc oxide, iron oxide, or nickel oxide in various proportions, or the nickel oxide may be replaced by cobalt oxide, chromium oxide, or copper oxide.  Other oxides such as titanium oxide or zirconium oxide may be used.  The ceramic material is a mixture of those materials usually used for ceramic bodies, glazes, or glasses.  A number of ceramic mixtures and oxide mixtures are described in the Specification.  The material thus formed is particularly suitable for producing electric resistances, or electric "insulators" which are electrically conductive or have an electrically-conducting coating.

Patent GB-805832-A (GB)
Title: Improvements in the manufacture of fuel briquettes
Inventor: DENT FREDERICK JAMES
IPC: C10B53/08
Filed: 1955-02-01
Abstract: 805,832. Carbonizing fuel briquettes; material for making coke. GAS COUNCIL. Feb. 1, 1955, No. 3011/55. Classes 55 (1) and 55 (2). A process for carbonizing fuel briquettes comprises passing a current of hydrogen or a gas containing at least 50 per cent hydrogen under a pressure well above atmospheric pressure, e.g. 10-25 atmospheres, through a charge of carbonizable briquettes, and reaction between the hydrogen and carbonaceous material of the charge is initiated by local supply of heat to the charge close to the place of admission of the gas and such supply of heat is then discontinued or suitably reduced, so as to cause a zone of reaction and high temperature to travel through the charge whereby the briquettes are carbonized. The local supply of heat may be provided by temporarily preheating the hydrogen or gas containing hydrogen, e.g. to 600 ‹C. The maximum temperature attained may be controlled by adjustment of the hydrogen content of the hydrogenating gas employed and the temperature attained may, for example, be lowered by diluting the gas with methane. A substance more readily reactive with hydrogen than the carbonaceous material of the briquettes may be admixed with the briquettes before treatment. Thus, e.g. a hydrocarbon oil of low volatility such as a high boiling coal tar oil may be sprayed on to the briquettes before carbonization. Alternatively a catalyst, such as sodium carbonate or calcium hydroxide, may be added to the briquettes to promote hydrogenation. The voids between the briquettes may be filled with a solid carbonaceous material which is preferentially hydrogenated, for example, a semi-coke or a coal. The hydrogenated residue from this added carbonaceous material may be recovered and briquetted for treatment by the process of the invention. The reaction may be effected in a series of vessels of the kind shown in Fig. 1 of Specification 519,246, and, after having initiated the reaction in one vessel by extraneous heat, and when the reaction in that vessel is complete, the reaction in a second vessel is initiated by passing in hot gas from the first vessel. Alternatively a single vessel may be operated continuously. In an example 30 parts of a weakly caking coal, 60 parts of a carbonaceous residue obtained by partial hydrogenation of a similar coal by the process of Specification 695,192, and 7 parts of a medium soft pitch are finely crushed, warmed to 80- 90‹ C. and briquetted under a pressure of 3 tons. A charge of these briquettes was carbonized by treatment with a gas containing 95 per cent of hydrogen under 50 atmospheres pressure and temporarily preheated to 600‹ C. A zone of reaction having a temperature of 950- 1000‹ C. travelled through the mass of the briquettes.

Title: Improvements in balancing arrangements for electricity supply in telegraph and other systems
IPC: H04L25/02
Filed: 1941-03-07
Abstract: 548,419. Electricity supply ; automatic control systems. STANDARD TELEPHONES & CABLES Ltd., TERRY, V. J., and HARGREAVES, T. F. S. March 7, 1941, No. 3106. [Class 38 (iv)] Voltage ; current. The voltages applied to two load circuits T 3 , T 4  and T 4 , T from a source T 1 , T 2  are equalised by means of thermionic valves in parallel with one or both load circuits. The effect is to add current to the more lightly loaded source, and vice versa so that current loads are also equalized. Condensers C 1  ... C 3  are provided to accommodate any large transilient currents. The invention is especially applicable to telegraph transmitters. The control grid of an amplifying pentode V 1  is held normally about 3 volts negative to the neutral conductor T 4   to which the cathode is connected. An increase in the neutral voltage will reduce the bulk current and the potential drop in a resistance in its anode circuit. The rise in its anode potential is transmitted to the grid of a valve or valves V 4 , normally about 10 volts negative to their cathodes so that they increase the load across the negative side of the system and restore balance. A second or phase reversing pentode V 2 . which may be connected in series with a resistance A across the negative side of the system and its grid, maintained normally about 5 volts negative to the cathode, also has its voltage raised by the aforesaid change in neutral voltage, so that the grids of a valve or valves V 3  across the positive side of the system connected to the anode of this pentode and through a resistance to the positive side of the system experience a fall in voltage and the current taken by these valves is reduced to assist in the balancing.
