Patent GB-226500-A (GB)
Title: An improved process and apparatus for the manufacture of carbon monoxide and hydrogen
IPC: C01B32/40
Filed: 1924-10-20
Abstract: 226,500. Michalski, K., (Assignee of Adam, C.). Dec. 17, 1923, [Convention date]. Hydrogen is produced by the action of superheated steam upon molten iron. In the preferred arrangement of plant, Fig. 1, carbon monoxide is also produced in a second generator B in communication with the hydrogen generator A. Oxygen, which is preferably superheated, is introduced through the pipe f into liquid iron in the generator B whereby ferrous oxide is formed which reacts with the block g formed by agglomerating ground coke with clay or pitch under pressure. Carbon monoxide escapes by the pipe h. The steam introduced into the hydrogen generator A through the pipe a is superheated by the iron in the passage D, but is prevented from reacting therewith by the layer of slag b.

Title: Improvements in or relating to printed circuits and methods of manufacturing the same
Inventor: AINSWORTH THOMAS ERIC
IPC: H05K3/24
Filed: 1962-07-02
Abstract: 964,557. Printed circuits. MARCONI CO. Ltd. April 2, 1963 [July 2, 1962], No. 25244/62. Heading H1R. In a method of making a " plated through" printed circuit, the ends of holes 3, bored in an insulating base 1 having a conductive coating 2, e.g. of Cu, on each side thereof, are bevelled by countersinking or, as shown, Fig. 4, dimpling; a resist material such as grease, silicone grease, printer's ink, pigmented oil or other waterrepellant material is applied. preferably by a roller, to the conductive coatings leaving the bevelled edges and hole walls exposed; the base is then immersed in or sprayed with a sensitizing material which deposits in the exposed areas, which are then electro-plated with metal and the resist is removed, e.g. by trichlorethylene, as shown in Fig. 5, in which M represents metal. Subsequently, the printed circuit pattern is formed by removing selected areas of the conductive coatings, as by etching with ferric chloride after an etch-resistant positive layer has been applied by a silk-screen, photo-litho &c. process. The base 1 may be of resin-impregnated paper or glass-cloth laminate. The sensitization step may involve immersion in or spraying with stannous chloride, followed by reduction coating with silver by spraying with or immersion in an ammoniacal solution of silver nitrate reduced by formaldehyde; alternatively, the laminate may be immersed in palladous chloride and subsequently electroless-plated with nickel. The sensitized areas are then plated by copper, followed by gold.
Patent GB-653588-A (GB)
Title: The manufacture of glyoxal and polyglyoxal
IPC: C07C45/60
Filed: 1948-09-28
Abstract: Glyoxal is manufactured by oxidizing acetaldehyde or paraldehyde with nitric acid in the presence of a small amount of nitrous acid; the reaction takes place at a temperature above the decomposition point of nitrous acid, and the escaping gases containing acetaldehyde are washed at a temperature preferably below the decomposition point of nitrous acid.  The washing liquid may be nitric acid or a portion of the reaction solution and in each case it is then passed into the reaction chamber.  The washing is preferably effected in a column charged with filling material and cooled with water, the washing liquid being sprayed from above.  The nitrous acid is produced in situ by adding sodium nitrite and even when operating continuously no further nitrite need be supplied after the commencement of the reaction.  The nitric acid used is preferably of S.G. below 1.4 and there may be present a catalyst such as selenious anhydride, vanadic acid or a manganese salt.  When operating continuously, the reaction product, comprising a solution of glyoxal, is removed continuously or periodically to keep a constant liquid level in the reaction chamber as fresh reactants are added.  The solution may be evaporated in vacuo to give solid polyglyoxal of purity greater than 95 per cent. An example is given.

Filed: 1967-06-02
Abstract: 1,149,573. Friction clutches. TWIN DISC Inc. 2 June, 1967 [6 June, 1966], No. 25537/67. Heading F2C. In an hydraulically operated friction clutch wherein friction discs H splined to a driving carrier E and a driven drum C2 are clamped together by axial movement of a piston K1 in response to supplying pressure liquid to a chamber 2, torque responsive means F1 are interposed between the carrier E and a driving shaft 1 so that when the transmitted torque exceeds a predetermined value the carrier E is moved left to close a valve I in the supply to the chamber 2 and thus reduces clutch engagement to maintain the transmitted torque constant. In Fig. 1, the torque responsive means comprises rollers F1 engaging cam recesses f2, f3 in the carrier E and a ring S3 splined to the driving shaft 1 and the valve I is formed by a surface 3 of the carrier E and a co-operating surface 4 fast with the driving shaft 1. Pressure liquid is supplied to a chamber 6 to move the carrier E to a position in which the valve I is open. When the torque exceeds a predetermined value relative rotation between the carrier E and ring S3 causes the rollers F1 to cam the carrier E to a valve closed position against the bias of the pressure in the chamber 6. A continuous bleed R thus reduces the pressure in the chamber 2 and increases the clutch slip to maintain the transmitted torque constant. The torque transmitted may be adjusted by adjusting the pressure supplied to the chamber 6. In a double clutch C1, C2, as shown, a double piston K1 is moved axially by selectively supplying pressure liquid to chambers 2 to engage the clutch C1 or C2. The pressure liquid is also supplied through orifices 1b and ducts 1a to cool the clutch discs H. In Fig. 2 (not shown), the carrier (E) is biased to a valve open position by a Belleville spring (C) and in Figs. 2 and 3 (not shown) the torque responsive means comprise balls (F) between cam surfaces (f, f1) respectively fast with the driving shaft (1) and the carrier (E). The clutch discs (H) are splined to an intermediate element which is ball splined at (M) to the driven member (B). In Fig. 4 (not shown) and Fig. 5, the torque responsive means comprises interengaging cam surfaces f4, f5 and the valve, Fig. 5, comprises a ball BB which is urged into engagement with a valve seat AA by a cam CC as the carrier E moves left. In Fig. 6 (not shown) a valve ball (FF) carried by the carrier (E) engages a fixed valve seat (GG) as the carrier moves left.

Abstract: 357,353. Feeding articles from shoots. WESTINGHOUSE LAMP CO., Bloomfield, New Jersey, U.S.A.-(Assignees of Meyer, P. ; 21, Voorhees Street, Newark, New Jersey, U.S.A.) Aug. 29, 1930, No. 25853. Convention date, Aug. 31. 1929. [Class 117.] In a machine for inserting contact pins in the bases of wireless valves &c., a base is fed by gravity down a shoot and then moved forward by a member from which it is released so that the contact pins enter the base, the pins being subsequently secured as by riveting. An electrical device is included to prevent the feeding of a base if an incorrect number of pins is delivered. Bases 24 fall down a shoot 22 having a slot 25 to engage a locating projection thereon, and are loosely retained in a recess in a forward portion of a sliding bar 28 by a spring- pressed lever. The bar is advanced by a cam 42 through links 34, 36 moving forward the base until it falls on to a member 11 carrying the suitably disposed pins and mounted on a conveyer 10. A plunger 76 then engages the base and forces it over the pins, being actuated through a spring 72 by a housing 60<1>, an arm 60, a rod 61 and a cam and followers 58, 64, 65. The base is then carried to a riveting &c. mechanism for securing the pins. The rod 61 further operates plungers 67, 68 forming part of the feeding device for the pins to the members 11, and also a member 104, Fig. 9, which, depresses a member 103 carrying plungers 98, 99 to contact with the set of pins in the next member 11 and urge contacts 109, 111 together. A solenoid 93 is thereby energized to retract a rod 89 to release a lever 78 through a toggle mechanism and permit the next base to fall. If one pin is missing, as in Fig. 9, the circuit is broken and a base is prevented from falling. The rod 89 is returned by a stop 96 and projection 95.
