Title: Apparatus and method for continuously electroplating metal on moving wire
IPC: C25D7/06
Filed: 1973-04-05
Abstract: 1372341 Continuously electro-plating wire STANDARD TELEPHONE & CABLES Ltd 5 April 1973 16274/73 Heading C7B A metal coating, e.g. Sn, Pb, Ni, Zn or Sn/Pb solder, is continuously deposited on a moving wire, e.g. of Cu or steel, by passing it e.g. from supply reel 2 a plurality of times through first one or more degreasing tanks 15, 18 then one or more plating tanks 23, 24, each time in a loop around two rotatable drums 17, 20 and 21, 22 respectively, at least one of each pair e.g. 17, 21 being driven, at least one of the plating drums 21, 22 being connected as cathode and one or more anodes 27 of the metal being deposited extending into the plating electrolyte contained in the plating tank(s); the speed of the driven degreasing drum 17 is varied with respect to that of the driven plating drum 21 depending on the wire tension e.g. in tension-controlling dancer arm arrangement 9. Grooved cylindrical rods 16, 19, 25, 26, or partially slotted comb-shaped structures, may be associated with the or each degreasing and plating tank for guiding the wire on to the associated drum and keeping the loops separate. The anodes, arranged above the sections of wire loops, may be step-shaped: one end covered by electrolyte rests on a shelf in the plating tank, the other rests on a bus-bar Fig. 5 (not shown). The lower surface of the anodes may be corrugated to provide a hydrodynamically rough surface above the wire loop sections; a perforated flow stabilizer plate Fig. 3 (not shown) may be arranged in the or each degreasing tank for the same purpose. Sections of the wire loops may pass into and out of the end of each degreasing/plating tank via a PVC weir (31), Figs 2 and 5 (not shown). A wash tank 10 may be positioned in the wire path between the degreasing and plating tanks. The plating tanks 23, 24 may be of PVC and contain an electrolyte comprising Sn (BF 4 ) 2 , glue or gelatine, #-naphthol and optionally a colouring dye. Degreasing may be effected cathodically using steel degreasing tank(s) as anode, containing a solution of NaOH and NaSiO 3 . Specifications 743404, 743405 and 1369323 are referred to.

Title: Improvements relating to automatic gain controlling arrangements for telecommunication systems
Inventor: RALPH FRANK
IPC: H04B3/10
Filed: 1952-06-27
Abstract: 732,555. Automatic volume control. SIEMENS BROS. & CO., Ltd. June 26, 1953 [June 27, 1952], No. 16297/52. Class 40 4). In a pilot-controlled gain-regulating system wherein the anode-cathode impedance of a valve is shunted across a path carrying the signal current, which path may be the main signal path or the feedback circuit of an amplifier in the main path, the control voltage derived from the pilot current is applied to control the anode-cathode impedance of the valve and to increase the percentage feedback around the valve, and also around the amplifier in the case when the valve shunts the amplifier feedback circuit. The intermodulation products arising from the use of the valve as a variable impedance are in consequence maintained at a predetermined minimum. The station shown which includes fixed equalizers EQL and EQS designed to compensate for frequency distortion in the transmission medium and the equipment respectively, has a network N in shunt across the input of amplifier LAA. The pilot current is selected from the output of a second amplifier LA by a filter PF, amplified in an amplifier PA, and applied to control a thermistor TH in the cathode circuit of valve VN through a rectifier U and an expander circuit which produces a large percentage change of control current in response to a relatively small percentage change of pilot current. A portion of the pilot current is applied over a full-wave rectifier PRA to energize, via a valve VA, a pilot fail relay PFA. The bias applied to the grid of valve VE in the expander circuit is the resultant of a standing bias across a condenser QL and the potential across a condenser QS in the output of rectifier U. A pulse source connected to terminals TS is arranged intermittently to cut-off the anode current of valve VE so that pulses of current varying in amplitude as the pilot current are applied to the heater of thermistor TH over a transformer TR. The supply of H.T. to valve VE through a potential divider comprising resistors RT and RV produces a sharp overload point which is made equal to the maximum rating of the thermistor heater. In the event of a pilot failure, the release of the pilot fail relay applies to the grid of valve VE the bias potential existing at the junction of resistors WB, WD. A high resistor RQ prevents the rapid discharge of storage condenser QH if there is a slow decline of the pilot current, and the combined capacities of condensers QK and QJ prevent re-operation of the relay PFA before the pilot has risen to its steady value after the replacement of a faulty component. The network N includes a network ZN (impedance Z), in series with a resistor RH (resistance R) across its terminals TN and the network impedance is stated as being equal to where g is the conductance of the valve VN at the working point determined by the pilot current. The Specification includes examples of component values.

Filed: 1931-06-06
Abstract: Azo dyes; dye preparations; azo dyes, forming on the material; cellulose esters or ethers, dyeing; printing.--New unsulphonated azo dyestuffs are obtained either by (1) esterifying a hydroxyl group of an unsulphonated pyrazolone azo dye with a carboxylic acid residue, or (2) coupling a diazo component with a pyrazolone, at least one of the components carrying a phenolic carboxylic ester group.  The products are suitable for dyeing cellulose esters or ethers and for use in printing, especially discharge printing with reduction discharge agents such as stannous salts (cf. Specification 346,751). The esterifying agents for (1) may be anhydrides or chlorides of aliphatic or aromatic carboxylic acids or even the free acids, and esterification may be effected in presence of organic or inorganic bases and/or of diluents.  For (2) an unsulphonated diazo compound carrying a phenolic carboxylic group may be coupled with an unsulphonated pyrazolone or a suitable unsulphonated diazo compound may be coupled with a carboxylic ester of a hydroxyaryl-3-methyl-5-pyrazolone.  Thus p-aminophenol may be diazotized, the diazo solution, after neutralization with sodium acetate, be stirred with acetic anhydride to acetylate the phenolic group, and the resulting solution be coupled with 1 - phenyl - 3 - methyl - 5 - pyrazolone. Other specified pyrazolones are 1-phenyl-5-pyrazolone-3-carboxylic acid, 1 : 3-dimethyl-5-pyrazolone and 1 - naphthyl - 3 - methyl - 5 - pyrazolones and the acetyl residue may be replaced by residues of other carboxylic acids, e.g. lactic acid.  In examples of (1) above the dyestuffs p - oxybenzene - azo - 1 - phenyl - 3 - methyl - 5 - pyrazolone, benzene-azo - 1 - p-hydroxyphenyl-3 - methyl - 5 - pyrazolone, and p - - oxybenzene - azo - 1 - (a  - naphthyl) - 3 - methyl-5-pyrazolone are acetylated by boiling for 2 hours under reflux with a mixture of acetic anhydride and acetic acid.  The dyestuffs may be produced on textile materials by coupling the appropriate components thereon or they may be applied in substance in aqueous solution, when sufficiently soluble, or as aqueous or other dispersions, especially dispersions obtainable by the methods described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 2 (iii), Dyes &c.].

Title: Improvements in the manufacture and production of hydrogen from hydrocarbons
IPC: C01B3/40
Filed: 1931-06-06
Abstract: Hydrogen is obtained from gaseous or vaporous hydrocarbons, having a higher molecular weight than methane by bringing the gases together with steam at a temperature of between 400 and 1000 DEG  C. into contact successively with at least two different layers of catalysts arranged one behind the other, the catalytic activity of each layer being lower than that of the next following one, while the temperature in each catalyst is lower than in the following one.  The catalysts are preferably selected so that the higher molecular and unsaturated hydrocarbons are converted at the beginning of the catalyst layer and the lower molecular hydrocarbons and methane towards the end of the layer.  Suitable catalysts include metals of the iron group, if desired activated by the addition of non-reducible oxides of metals from groups 2 to 6 of the periodic-system, e.g. aluminium oxide, magnesium oxide, uranium oxide, cerium oxide, chromium oxide, vanadium oxide, beryllium oxide, calcium oxide, strontium oxide, barium oxide, titanium oxide or molybdenum oxide. The catalysts in the first layer may be employed with a smaller amount of activating agent or in a physical condition of lower activity (e.g. as glowed oxides) than in the following zone or zones, or they may consist of a metal of the iron group made into an aqueous paste with a hydraulic binding agent and allowed to set.  Substances which lead to the formation of soot, such as silica and other gels, must be avoided.  Catalysts obtained according to Specification 376,358 may be employed in the first part of the reaction chamber, and those obtained according to Specifications 267,535 and 323,855, [both in Class 1 (i), Chemical processes &c.], at the end of the reaction chamber.  Specification 288,662, [Class 1 (i), Chemical processes &c.], also is referred to.

Abstract: 1,107,418. Air humidifier. BRAC Ltd. 15 April, 1966 [25 Nov., 1965; 26 Jan., 1966 (2)], No. 16748/66. Heading B1R. In an air humidifier of the type wherein a stream of air is contacted with water drawn from a reservoir by a pump 24 and fed to a disc 24a surrounded by an atomising ring 23, pump and disc being rotated by an electric motor 17, the electric motor is cooled by air drawn into a casing 18 within which the motor is located by a fan 28 from a place remote from the aperture through which humidified air is discharged, the cooling air being discharged through an opening on a plate 19 thereby to protect the motor against ingress of waiter atomised by the rotating disc 24a. The casing 18 has spaced-apart walls 20 and 21 between which the cooling air is drawn and is surrounded by a dome 10 humidified air being discharged from an opening 10a after passage through the space between wall 21 and the dome 10. As shown in Fig. 4 (not shown) the opening 10a may have a rotatable discharge nozzle 35. The dome 10 rests on the flange 5 of the water reservoir 2 and may be raised or lowered thereon to vary the crosssectional area of the passage between wall 21 and the dome and hence regulate the output of the humidifier. Air to be humidified is admitted through holes 4 in the flange 5 and the dome may have a ring 11 of L-section with openings 12 which by rotation of the dome can be brought more or less into register with holes 4 to vary the air intake. The air to be humidified passes beneath a plate 32 and enters the humidifying zone through a central aperture in the plate. The plate 32 may have openings whereby a certain amount of the humidified air can be recirculated within the humidifier and not be discharged. The operation of the humidifier may also be controlled by varying the amount of water fed to the pump 24d. For this purpose the lower end of the pump is located in a well in the reservoir and water is admitted to the well through openings which can be varied in size from outside the humidifier.
