Title: Method of Electroplating
Inventor: CHAUVIN GUY
IPC: G01T1/11
Filed: 1967-12-27
Abstract: 1,184,393. Electro-plating. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec.27, 1967 [Jan.31, 1967], No.58730/67. Heading C7B. [Also in Division G6] A method of electro-plating an object at least the surface of which consists of U, Pu, U-base alloy or Pu-base alloy (e.g. a rod or plate intended to serve as nuclear fuel) comprises the successive steps of electro-depositing a layer of a metal (e.g. Ni or Cu) which adheres to the surface of the object; electro-depositing at least one layer of Sn, Zn, Pb or In; mechanically surface flattening the surface whereby the pores and/or surface irregularities are closed, a smooth outer surface is obtained and the Sn, Zn, Pb or In is rendered impervious to outside agents, the total thickness of the plating after flattening being greater than 55 microns. In an example a plate of U-base alloy is (a) degreased and pickled by degreasing with trichloroethylene, electrolytic degreasing in a solution containing a wetting agent and 40 g/1 NaOH at 5 to 10 A/dm , pickling with HNO 3 , HCl and then HNO 3 ; (b) electrolytically plated with 40 to 50 microns of Ni by electrically connecting it as a negative pole followed by dipping it in a bath containing nickel sulphate and chloride and KA1(SO 4 ) 2 . 12H 2 O at 45‹C. and at a pH of 3Œ 0À25, the current density being progressively increased to 2À5 A/dm<SP>2</SP>; (c) washed, dried weighed, thickness measured and surface irregularities removed; (d) heat-treated to enhance the adhesion of the Ni; (e) retouched to fill in any flaws in the Ni layer by electrolytic "spot" deposition of Ni or Sn; (f) prepared for Sn plating by electrolytic degreasing in an alkaline bath; (g) electrolytically plated with 40 microns of Sn by dipping it at low voltage in a bath containing Na 2 SnO 3 .3H 2 O and NaOH at 70 degrees and increasing the current density to 2À5A/dm<SP>2</SP>; (h) washed, dried, surface irregularities removed by electrolytic spot deposition of Sn followed by buffing or polishing; and (i) mechanically flattened by rotary brushing, the brush may contain a fine grit abrasive.

Title: Duplicating system
IPC: B41M1/42
Filed: 1967-12-29
Abstract: 1,212,370. Printing-apparatus. RANK XEROX Ltd. 29 Dec., 1967 [4 Jan., 1967], No. 59085/67. Heading B6C. An image 2 on a relief printing plate 1 is printed on to a sheet or a web 31 by inking the plate with dry ink particles from an inking roller 11 and transferring the inked image on to the web 31 &c. utilizing pressure and a source of potential 41 which establishes a potential difference between the plate 1 and a transfer roller 33. The printing and non-printing areas of the plate 1 are each formed of the same material. The powdered ink is supplied to the roller 11 by gravity from a hopper 17 and comprises fine pigmented electroscopic particles together with coarser carrier material which is triboelectrically charged with a polarity opposite to that of the pigmented material on frictional engagement therewith. Electrodes such as 14 which may be in the form of a curved sheet, a screen, or a series of wires or points maintain a layer of charged particles on the roller 11. A potential source 21 effects the ink transfer to the plate 1 which is spaced up to 3 mm. from the roller 11 and a brush 61 assists the removal of excess ink after printing. The printed image is fixed by a heating unit 45, vapour fusion, spraying &c. with an adhesive film, or by lamination. The roller 11 includes a metallic surface 13 supporting a semi-conductive layer 12. The printing surface may include a conductive layer supporting a thin semiconductive or dielectric coating, may print on to conductive material, and may alternatively be mounted on a flat bed.

Abstract: 1,255,277. Launching ships. VEROLME MACHINEFABRIEK IJSSELMONDE N.V. 4 Dec., 1969 [4 Dec., 1968], No. 69164/69. Heading B7S.  A launching assembly for a ship 1 on a slipway 6 comprises a slide frame or cradle 3 supporting the ship and slidably mounted on greased stationary shootways 5, the cradle being held in position prior to launching by a plurality of rods 13 coupled by threaded sleeves or tumbuckles 14, 15 to lugs 11, 12 pivotably connected by pins 9, 10 to brackets 7, 8, an explosive charge being located within one or both sleeve chambers 17 to break the sleeves for launching. The sleeves are reduced in thickness at 16 to facilitate breakage. The unthreaded portion of rod 13 is of reduced thickness and the rod is of soft steel to facilitate breakage of the rod, in case some of the explosive charges do not explode, the rod strength being such that a small percentage of the total number of rods, e.g. 20%, when acting alone, will not hold the ship. The rod material also permits stretching of the rods to accommodate different stresses along the cradle. The rods also may be adjusted by sleeves 14, 15 to accommodate different stresses. Twin detonator leads may be used for each explosive charge to ensure firing.

Abstract: 1,208,919. Chlorine nitrate. NORTH AMERICAN ROCKWELL CORP. 29 Dec., 1967 [29 Dec., 1966], No. 59215/67. Heading C1A. Chlorine nitrate is produced by reacting chlorine monofluoride with anhydrous HNO 3  (nitric acid). The reaction is fast and is possible at any temperature above the m. pt. of C1F (-155À6‹ C). In the preferred process, both reactants are frozen into a closed, evacuated container, preferably of stainless-steel or perhalogenated plastics. Upon warming (if necessary up to 225‹ C.) reaction ensues, proceeding satisfactorily in either liquid or gaseous state. On completion of reaction the container is opened successively to traps at -142‹ C. and -196‹ C., ClNO 3  being largely condensed into the - 142‹ C. trap. The contents of this trap may be further purified by fractionation.

In a sparking plug central electrode assembly having a thimble 17 at the sparking end which is adapted to be filled with silver 16 or other metal or alloy of good heat conductivity in electrical and thermal contact with the firing tip of the central electrode 15, the thimble is provided with an inner shoulder, flange or other projection 18 at its open end or intermediate its ends for engagement with an internal shoulder 14 in the bore of the insulator 12 to be supported thereby and a second projection 25 located at the closed end of the thimble 17 for abutment against the end of the insulator 12, the two projections 18, 25 serving to maintain a radial clearance between the thimble and the insulator bore throughout the length of the thimble 17 between the projections. An extension 19 at the end of the central electrode 15 passes through a seal 20 into the mass of silver 16 or similar material which has the thimble 17 on the outer end to form the sparking tip, the thimble being held in spaced relationship with the bore of the insulator 12 by the projections 18, 25 to avoid damage to the insulator upon expansion of the metal parts. The thimble 17 is made of such. material as platinum, nickel, alloys containing either of these metals or any suitable heat resisting alloy steel. In a modification, a separate sparking tip of platinum or platinum alloy is formed on the end of the thimble by riveting, welding or brazing, in the former case the inner rivet head abuts the silver core to enhance the electrical and thermal contact therewith. In another modification, the inner projection is moved nearer the seal so that the length of the thimble is increased. In a further modification, the thimble is increased in length and the inner projection is arranged intermediate its ends. The inner projection is formed after the thimble has been inserted in the insulator; the silver in the bore may be subjected to both heat and pressure during assembly of the plug. The first Provisional Specification describes also a sparking plug in which the thimble is unsupported at the firing tip end by the outet projection.

Title: Thrust reversers
IPC: F02K1/56
Filed: 1978-09-28
Abstract: The invention utilises the phenomenon of momentum drag to brake the landing run of an aircraft powered by a gas turbine engine. A mass of air over and above that accelerated to the speed of the aircraft 10 by the compressor of the gas turbine engine 16, is induced to flow through the duct portions 38b via the exhaust nozzle 44 and is ejected from outlet 34 adjacent the thrust reverser outlet 22 outlets 34, 22 being located on opposite sides of a means (e.g. blocker doors 42) which blocks normal gas flow and ejects it through outlet 34 in a thrust reversal position. The momentum drag is thus amplified with resultant increase in braking effect. <IMAGE>
