Title: Electroplated anodized aluminium articles and process therefor
IPC: B01J23/00
Filed: 1974-05-14
Abstract: 1473347 Anodizing and plating aluminium HA FROMSON 14 May 1974 [18 May 1973 7 March 1974] 21348/74 Heading C7B An Al substrate e.g. web is anodized and electroplated, batchwise or preferably continuously by introducing anodizing D.C. into the Al in a cathodic contact cell containing a platable metal, the Al having an anodic oxide-coating formed thereon before entering the cell, to form an unsealed porous anodic oxide layer thereon with randomly distributed discrete metal islands each having a root portion anchored in one or more pores of the oxide layer. As shown an anodizing cell is followed by a contact cell, each provided with suitable rollers to guide an Al web. The cathode of the anodizing cell and anode of the contact cell may be connected to the same D.C. source (a, b, d); plating may be caused by the same current (a) or from a separate D.C. source (b, d). Alternatively anodizing and plating currents from separate sources may be introduced into the web via contact rolls (c). Anodizing may be effected with single or multiphase A.C. Metals plated may be Cr, Cu, Sn, Zn, Ag, Ni, Au, Rh or alloys thereof. The portions of oxide layer remaining after plating may be scaled and dyed. Prior to anodizing the Al substrate may be cleaned or degreased, and pre-formed into rolled or honeycomb configuration. A photosensitive layer, e.g. dichromated colloid, photopolymer or diazoresin, may be applied to the oxide layer surrounding the metal islands to form a lithographic printing plate. Alternatively a catalytically active metal e.g. Fe, Co, Ni, Pd, Pt, Ru, Rh, Mn, Cr, Cu, Mo, W or rare earth metal, may form the metal islands in a composite catalyst body. For electroless plating of metal on to a non-conductive substrate, a non-conductive layer, e.g. of phenolic, epoxy, AB5, polyethylene, polypropylene resin or nylon, is laminated to the anodized and plated Al article, then the Al substrate and anodic oxide layer is removed e.g. by chemical etching to leave discrete metal islands imbedded in the non-conductive layer, preferably also removing the metal islands to leave undercut pores, to serve as sites for subsequent electroless deposition, or deposition of nucleating agents for such deposition. A different metal e.g. Pb or Sn may be electro-plated on to a discontinuous electro-plated Cr surface. Specification 1407947 is referred to.

Title: Improvements in or relating to the production of stiffened fabrics and articles made thereof
IPC: D06M17/02
Filed: 1935-07-29
Abstract: 460,523. Compound fabrics. BRITISH CELANESE, Ltd. July 29, 1935, No. 21464. Convention date, Aug. 4, 1934. [Class 140] A stiffened compound fabric suitable for wearing-apparel e.g. for collars, cuffs, and fronts of shirts, hats and parts thereof, and garment linings is made by uniting under heat and pressure the components of an assembly comprising a textile fabric, consisting substantially of non-thermoplastic material, coated or impregnated with cellulose acetate or other thermoplastic cellulose derivative applied in finely divided form, and two outer layers of untreated fabric composed substantially of non-thermoplastic material. The cellulose derivative may be powdered by grinding in a ball or pebble mill in the presence of water or other liquid, or by passing with water or other liquid and, if desired, a plasticizer, such as dimethyl or diethyl phthalate or dibutyl tartrate through a colloid mill having closely fitted rotors one or both of which is provided with an abrasive surface e.g. of carborundum, and may be applied as a suspension e.g. in water, or as a dry powder. Adhesives such as gelatin, gum arabic, gum tragacanth, &c. or latex may be incorporated with the finely divided cellulose derivative. Woven, knitted, netted &c. fabrics of cotton, linen, wool, silk, regenerated cellulose &c. with or without thermoplastic cellulose derivative yarns may.be used. In examples two or three lavers of cotton or linen fabric are assembled and hot-pressed with one or two intermediate layers coated or impregnated with powdered or finely divided cellulose acetate. The fabric layers may be cut to shape and/or sewn together before hot-pressing. A volatile solvent or latent solvent such as acetone, ethyl lactate, formal glycerol, ethyl and/or methyl alcohol, or methyl glycol, preferably diluted with water may be present during hot-pressing. The latent solvent e.g. aqueous alcohol may contain a plasticizer in solution. The pressure surfaces or rollers, one or both of which may be heated, may be embossed with designs, stripes, dots &c. to give local adhesion. In an example cellulose acetate, dimethyl phthalate, gum tragacanth, and water are passed through a colloid mill having carborundum rotors, then treated in a ball or pebble mill, the resulting suspension being applied to a cotton fabric, and dried. The coated fabric and two untreated outer cotton fabrics are treated with aqueous ethyl alcohol and united by hot-pressing.

Title: Improvements in or relating to the operation of a heat exchanger in a steam generator
IPC: F22G5/20
Filed: 1957-07-08
Abstract: 819,106. Water-tube steam boilers. SULZER FRERES S. A. July 8, 1957 [Feb. 27, 1957], No. 21566/57. Classes 123(2) and 123(3) A steam generator has three series-connected superheater stages 1, 2, 3 each having a radiantly-heated section S1, S2, S3 and a convection-heated section B1, B2, B3 respectively, the two sections in each stage being connected in parallel. The total amount of steam produced in the generator flows to the first stage 1 through a rotary valve D1 which divides the steam between the sections B1, S1. Temperature measuring means T1a, T1b are provided at the outlets of sections S1, B1 respectively and transmit to a regulator R1 in which the temperatures are compared. If there is a difference in temperature (due, for example to a rise in load when the steam from section S1 will drop in temperature whilst that from section B1 will rise) the rotary valve D1 is adjusted by the regulator to alter the flow in the sections B1, S1 until the outlet steam temperatures both assume the same value. Downstream of the temperature measuring means T1a, T1b the divided flows of steam are reunited in a mixer M1 and passed successively through rotary valves D2, D3 to the next superheater stages where the process is repeated. Fig. 2 shows the mixer M1. The outlet pipe b from the section S1 is connected by a T-junction to a common outlet pipe a while the outlet pipe c from section B1 passes through the wall of the pipe b into the interior of the pipe a and carriers at its end guide blades e which impart a whirling motion to the steam and a centrally disposed body f which deflects the steam outwardly. Guide plates g giving an opposite direction of whirl are mounted in the annular space d between the pipe a and the end of the pipe c the two streams being thoroughly mixed within the pipe a. The method can be applied to the economizers, evaporating sections or superheating sections of forced flow or natural circulation boilers.

Title: Augmented perspective radar display
Inventor: YOUNG DAVID W
IPC: H01Q15/00
Filed: 1976-05-25
Abstract: 1525835 Perspective radar D W YOUNG 25 May 1976 [28 May 1975] 21623/76 Heading H4D A perspective radar system, such as that of USA Specifications No. 3,778,821 and No. 3,896,432, has its display 39 augmented so as to provide a display 40 in perspective as it would appear if the observer were at a different position from his actual position. This different position may be in altitude, in range, or a combination of both. The sweep wave form voltage function applied to the vertical input 32 of the cathode ray tube display 15 is modified to correspond substantially to that which would be generated if the radar antenna 17 were at such a different position. This is done by manual control of a synchronizing pulse delay circuit 19, inserted between the radar pulse repetition frequency trigger signal generator 18 and the transmitter 20, and/or of a simulated altitude generating circuit 36 connecting into the altitude control circuit 35 which feeds into the sweep and control circuit 25. The radar may be incorporated in aircraft or ships. The antenna 17 transmits radar pulses in the form of a fan-shaped beam 13 lying in a vertical plane and scanning in azimuth over angles # from a centre position. Echo signals pass through video amplifier 23 to input 33 of display 15. An electron beam is moved horizontally back and forth across the screen in precise synchronism with the movement of beam 13 by the signal generated from the position sensor 28, passed through horizontal amplifier 29 to horizontal input 31. The same electron beam also sweeps from the bottom to top of the screen at a rate controlled by the sweep wave from voltage function received in vertical input 32 from vertical amplifier 26 and circuit 25. The vertical sweep frequency is many magnitudes higher than the horizontal movement of the antenna beam and electron beam. The echo signals in the form of video signals at input 33 modulate the beam so that the brightness of the screen fluorescence increases in proportion to the strength of the video signal so that the various targets are displayed on the screen. The real altitude signal from box 34 is fed to circuit 25 to render the display in perspective. The sweep in the vertical direction changes with time in the form of a hyperbolic function, the specific shape of which is determined by the altitude, Fig. 4 (not shown).
