Title: Natural gas substitute from naphtha - by steam reforming in two stages with hydrogen recycle to second stage
IPC: C10G11/04
Filed: 1973-11-06
Abstract: A natural gas substitute is produced from naphtha by (a) subjecting 10-50% of the naphtha feed to steam reforming at 700-780 degrees C and 50-100 bar with an H2O/C ratio of 2-4 in an externally heated tubular reactor in the presence of a catalyst contg. (i) >=70% uncombined MgO and (ii) Co and/or Ni introduced at least partially by impregnation, the total amt. of Co and/or Ni being =20% (expressed as CoO and NiO) and the amt. introduced by impregnation being =12%; (b) introducing the product gas from stage (a), the rest of the naphtha feed and recycled H2 into an unheated reactor contg. one or more beds of the same catalyst as in (a) and subjecting the mixt. to steam reforming at 500-580 degrees C and 50-100 bar with an amt. of steam such that the total H2O/C ratio for (a) + (b) is 1.8-3; and (c) removing H2O and CO2 from the product gas, opt. compressing it, scrubbing it with a hydrocarbon solvent, recycling at least part of the sepd. H2 to stage (b), and treating the soln. of CH4 in the hydrocarbon solvent to separate a CH4-rich gas. The use of conventional externally heated tubular reactors, which are costly and difficult to charge with catalyst, is restricted to the conversion of only a small part of the feed; the catalyst (FR.2036480) allows low temps. and low H2O/C ratios to be used without coke formation; recycling H2 from (c) to (b) allows good yields of CH4 to be obtained. The part of the naphtha feed introduced into stage (a) is pref. pre-desulphurised by reaction with H2 from stage (c).

Title: Electrodeposition of nickel-iron alloys - for use in transducers, plating soln. contains thiocyanate ions to increase nickel-iron ratio
IPC: C25D7/00
Filed: 1973-12-11
Abstract: Addn. of sufficient NaCNS or other thiocyanate to the electrolyte for co-deposition of Ni and Fe increases the Ni:Fe ratio in the deposit. Anomalous deposition and variation in the Ni-fe alloy compsn. are thus inhibited without redn. of current and consequent increase in plating time. Paired films of this type on suitably masked metallised substrates can form the yokes of electromagnetic recording transducers.

Title: Glass bubbles formed by dropping molten glass on porous wet surface - for use as a light diffuser
IPC: C03B19/08
Filed: 1975-02-18
Abstract: A glass bubble is made by allowing a small measured quantity of molten glass to fall onto a surface of a heat resistant material which is porous and wet, such that as the glass drop spreads it entraps air and steam which are expanded by the heat of the glass so as to blow the glass drop into a bubble formed of a number of internal bubbles. The tool for effecting the process comprises a plate of the heat resistant porous material enclosed between two metal plates, the upper one having an opening which limits the lateral expansion of the bubble, and the lower one which has a handle attached to it is for supporting the heat resistant porus material with its upper metal plate in such a manner that the tool can be oscillated so that the expansion of the bubble can be controlled. The bubbles are used for diffusing light produced from an electrical illumination appts. The bubble produces an aesthetically pleasing effect, and can be used as a lustre or decoration and may be coloured or clear.

Title: Thermally compensated clamps - for carbonation of carbon fibre or graphitic laminates, to prevent overstressing of clamping plates
Inventor: REBAUDIERES JEAN
IPC: C04B35/83
Filed: 1975-12-08
Abstract: A jig for clamping together a composite structure involving carbon fibres or compacted graphite prior to hot deposition of carbon from a vapour phase (i.e. CH4 at 1100 degrees C), comprises spacers made of a thickness and composition which compensates for thermal expansion and contraction parallel to the clamping length of the main jig components during the thermal cycle. The sepn. distance of the clamping plates may be maintained constant or allowed to contract or dilate by a small and controlled amt. during the thermal cycle. Exposure and coating of the core faces and consequent distortion or cracking of the (carbon) clamping plates on cooling about an over-size core is thus avoided.
Patent FR-2344131-A1 (FR)
Title: Avalanche diode with rectifying contact between differing layers - has very low series resistance and wide applications
Inventor: KRAMER BERNARD
IPC: H01L29/868
Filed: 1976-03-12
Abstract: An avalanche diode of low transition time has a rectifying contact between two semiconducting materials having differing types of conductivity. The first semiconducting material comprises three main layers, the active layer, in contact with the second material, the substrate layer constituting the mechanical support and having a very high concn. of impurities, and an intermediate layer between the two layers. The concn. of impurities in this intermediate layer is between that of the two adjacent layers. The thickness of the active layer and its average concn. in impurities form a linear relationship between the two following limits;- 0.85 M correspg. to 1016 atoms/cm3 and 0.35 M correspg. to 4.1016 atoms/cm3 with a tolerance of plus-or-minus 0.1 M on the thickness of the active layer. The ratio of the thickness of the avalanche zone in the active layer to the thickness of the latter is >0.75. The transition between the levels of the concns. of impurities in the frontier zones of the active layer and the intermediate layer has a thickness of 0.15 M. The first mentioned material has N type conductivity and is gallium arsenide. Provides an avalanche diode of brief transition time, the thickness of the transition zone being slight, and which by the intermediary of a layer with a fixed amt. of impurities between the substrate and the active layer, presents an active length of fixed value. The negative dynamic resistance for the output oscillation offered by a diode of this type, is low which makes it possible to avoid parasitic oscillation. This diode also offers a very low series resistance due to the slight thickness of the layer of low conductivity. The diode has wide application, e.g. in frequency multipliers.

Title: Zinc phosphating esp. ferrous metals - with automatic control of additives
IPC: C23C22/77
Filed: 1976-04-22
Abstract: Metals are given a coating of Zn phosphate by (1) treating the surface with an acidic phosphating soln. contg. Zn, phosphate and alkali metal ions, (2) recharging the soln. as the coating thickness increases by adding (a) a material contg. Zn and phosphate ions and (b) a material contg. alkali metal ions such that (b) has an alkaline reaction w.r.t. (a), and (3) making the compsn. of the phosphating soln. the optimum by adding (a) and (b) in predetermined amts. During the treatment the conductivity of the soln. is maintained constant for a specific temp. by adding (a) or (b). Automatic Zn phosphating is achieved at the same time maintaining the compsns. of the phosphating soln. content. It is possible to use the conductivity of the soln. as an indicator for the addn. of more of the constituents right from the beginning of the process. There is also less waste.
