Title: Improvements in or relating to methods of forming a layer of an alloy on a support
IPC: C23C26/00
Filed: 1962-01-19
Abstract: An alloy layer consisting of two or more constituents is formed on a support for a semiconductor body (see Division H1) by applying a first layer of the constituent having the higher or highest melting point, applying a second layer of the other or a second constituent in excess of that required to form the alloy, similarly applying a third layer of a third constituent if present, heating the layers at a temperature below the said melting point to diffuse the lower melting point constituent(s) into the solid higher or highest melting point constituent and removing the excess lower melting point constituent(s), e.g. by etching. The second layer may be subjected to diffusion heating and also excess constituent removed before applying any third layer.  For a gold-antimony alloy layer, the heating is below 360  DEG C.  For example, a plurality of supports of Fe-Ni-Co alloy etched in concentrated HCl are first provided with a nickel layer from an electroplating bath containing 200 g./l. NiSO4.6H2O, 20 g./l. NiCl2.6H2O and 25 g./l. H3BO3 with current at 6 amps. for 1/2 hour; then with a gold layer from an electroplating bath containing 10 g./l. KAu(CN)2, 7 g./l. KCN and 30 g./l. K2CO3.2H2O with current at 3 amps. for 2 hours; finally with an antimony layer from an electroplating bath containing 50 g./l. K-Na tartrate.4H2O, 5 g./l. KOH, 5.5 g./l. K-SbO tartrate. 1/2 H2O and 10 g./l. K2CO3.2H2O with current at 5 amps. for 1/4 hour; the supports are subsequently heated at 300 DEG C. for 1/2 hour to obtain a solid solution of Au containing 0.2 at. per cent Sb, excess Sb being removed in hot concentrated H2SO4.

[Class 98 (i).] In an exposure meter for photographic purposes comprising a photoelectric cell connected to an electrical measuring instrument, the cell is of the self-generating type and is enclosed with the measuring instrument in a casing of cylindrical form. The meter shown in Fig. 1 comprises a cylindrical casing 1 into which the light enters through a grid 8 and window 7 to impinge on a plate-like photo-cell 6. A measuring instrument including a permanent magnet 3 is in circuit with the cell and indicates by means of a pointer and scale visible through a window 2. A tabular calculator is provided comprising a slotted ring a, Fig. 5, rotatable on the casing. Scales 10, 11 and 12, 13 on the casing and ring, respectively, are graduated in terms of diaphragm apertures, meter readings, exposure times and the light sensitivity of the plate. The ring may act as a cap to exclude light from the meter and the scales may be marked either on the flat or curved surfaces of the ring and casing. To enable the sensitivity of the measuring instrument to be adjusted, the permanent magnet 3, Fig. 6, is provided with an adjustable shunt 10 carried by a rotatable arm 9. To enable the meter to be used in measuring a series of ranges of light intensity, a corresponding number of caps b, Fig. 9, having apertures c of various sizes are provided to exclude the desired proportion of light from the photo-cell.

Title: Improvements in the manufacture of vulcanised rubber articles
IPC: B29C35/02
Filed: 1943-02-15
Abstract: In the vulcanizing of rubber articles, particularly the rubber covering of electric wires and cables, the rubber body is enclosed in a composite covering consisting of alternate layers of vulcanized and unvulcanized rubber compound, the inner layer being unvulcanized, and subjecting the whole to heat treatment.  If it is desired to remove any of the layers after vulcanization, the outer layer to remain is treated, as by covering with french chalk, to prevent it from becoming vulcanized to the overlying layer.  The layers are preferably applied by helically wrapping strips of material round the body.  The body may include a material for generating gas during heating to produce a cellular body, the covering layers extending during the action and then uniting with the body to form an unbroken skin.

Abstract: <PICT:0394050/III/1> <PICT:0394050/III/2> <PICT:0394050/III/3> <PICT:0394050/III/4> <PICT:0394050/III/5> In apparatus for ionizing gases, especially for the electrical purification of gases by a process in which ionization is produced by an electric field having a substantially plane surface and a second electric field is provided to attract the ions formed into the gas to change the suspended particles, for example as described in Specification 371,398, the ionizing field is produced at a substantially flat surface of a plate of insulating material which separates the electrodes of different polarities.  The ionizing electrodes of one or both polarities may be embedded or affixed to the surface of the insulating plate, for example by spraying, burning, painting or cementing, in the form of rods, strips, grids, nets or plates.  Alternatively, one set of electrodes may be set at a depth in the insulating plate and the other set arranged near or on the surface thereof.  The insulating plate may be made of any suitable non-conducting, badly or semi-conducting material.  In the example of construction shown in Fig. 1, two series of rod-shaped conductors 12, 13, each connected in parallel, are embedded near the surface of the insulating plate 11. These are preferably arranged in <\>aechelon.  The conductors may also be arranged on the surface of the plate.  Fig. 5 shows an arrangement in which one set of electrodes 31 is embedded in the plate 11.  The other set 32 may be arranged on one side of the plate as shown, or may be duplicated on both sides of the plate, all the external electrodes being connected together.  In a further modification shown in Fig. 7, the internal electrodes 36, 37 may be duplicated and connected together in parallel.  In these arrangements, the plate may be formed with a collar or thickened at one end to screen the ends of the external electrodes from the lead to the internal electrodes.  Fig. 9 shows an arrangement having two sets of electrodes 53, 54 of opposite polarities on the outer surfaces of the plate and having a conducting plate or hollow space 51 filled with conducting dust or liquid, or a series of such layers, embedded in the plate.  These plates or layers may also form one electrode of the ionizer, the other electrode comprising the surface electrodes connected in parallel.  Fig. 12 shows the application of the ionizer to an electrical precipitator of the type described in the above-mentioned Specification, the gas passing between ionizing electrodes 27, 28, supplied from an alternating current source 20, and precipitating electrodes 65, 66 supplied from a direct current source 70, the voltages being so arranged that a direct current field exists between the ionizer and each precipitating plate.

Abstract: 210,797. Syndikat f³r Gasforschung, (Assignees of Estnische Stein÷l-Akt.-Ges.). Feb. 1, 1923, [Convention date]. Gaseous-fuel furnaces.-In the dry distillation of bituminous materials the material is subjected simultaneously to the action of radiated heat from burning gases and to convection heating by a current of hot gas such as producer gas. The material is introduced through a conduit 8 into a drying-drum 5 in which it is treated by hot gases from a flue 6 and air from a pipe 7, the dried material passing through a charging-device 4 on to an endless chain 2 bv which it is moved through the chamber 1 and discharged into a producer 11. The producer gases from channels 15 and openings 14 partly pass through the charge and are led away together with the distillates through an outlet 20 and partly are burned by the admission of air through nozzles 16, thus forming a hot zone over the material, the combustion products escaping by channels 18 into the flue 6.
