Filed: 1972-07-10
Abstract: 1412631 Measuring fluid pressure electrically; pressure gauges GEORGE KENT Ltd 10 Oct 1973 [10 July 1972] 32202/72 Headings G1L and GIN A differential pressure transducer for use, e.g. in fluid-flow measuring systems comprises a housing a pair of diaphragms located in the wall of the housing and forming with the housing respective chambers connected to sources of the fluids having the measurable differential pressure, and a rigid member connecting the diaphragms and displaceable in response to the differential pressure. Part of the volume enclosed within the housing is filled with a substantially incompressible fluid; the remainder is filled with a material such that the combined thermal expansion or contraction of the fluid and the material is substantially equal to that of the housing, for avoiding errors that might arise if the diaphragms were both to be deflected outwardly by internal pressure. Each of diaphragms 16 welded to opposite ends of a stainless steel housing 11 is also welded to a retainer ring 17 which forms a fluid pressure chamber 19 sealable by a ring 20. The diaphragms 16 are connected by a stainless steel rod 21 to which electrical connection (not shown) can be made. The space enclosed within the housing is mostly occupied by a pair of borosilicate glass blocks 14; the remainder is filled by a suitable oil through a filler inlet (not shown). A disc 22, which may be formed coaxial with the rod 21, forms one electrode of a differential capacitor, of which the other electrodes are conductive layers 25, 26 deposited on opposed faces of the glass blocks 14 and terminated at connectors 31, 32 via inserts 33, 34 and leads 35, 36. The diaphragms may comprise corrugated discs as illustrated, or bellows. The differential capacitor may be connected into a bridge circuit measuring the displacement of the rod 21 as a function of differential pressure. A force-balance system may be added to restore the rod 21 to a datum position.

Title: Manufacture of nitrogenous derivatives of the anthraquinone series
IPC: C09B1/50
Filed: 1932-11-18
Abstract: Aminoanthraquinone derivatives are prepared by heating leuco-1.4.5.8-tetraoxyanthraquinone or leuco-1.4-dioxy-5.8-diaminoanthraquinone or a N-alkyl derivative thereof at a temperature above 100 DEG  C. in an aqueous solution of ammonia or of a primary aliphatic amine, preferably in presence of a small proportion of a reducing agent, and the leuco body thus produced is oxidized to the corresponding anthraquinone derivative which is sulphonated, if desired.  A modification of this process consists in starting from the corresponding unreduced anthraquinone derivative and conducting the process in presence of a correspondingly larger proportion of a reducing agent.  By working according to such processes 1-oxy-4.5.8-triaminoanthraquinone or its Nalkylated products are obtained; these are dyestuffs for acetyl cellulose and on sulphonation yield soluble wool dyes.  In examples (1) leuco-1.4.5.8-tetraoxyanthraquinone is heated at 120 DEG  C. in presence of a little sodium hydrosulphite with aqueous ammonia, methylamine and oxyethylamine to give 1-oxy-4.5.8-tri-amino-, tri-methylamino-, tri-oxyethylaminoanthraquinones respectively on oxidation: (2) the same starting-material is heated at 120 DEG  C. with aqueous ammonia alone in a closed vessel to give a triamino derivative as above; it dyes acetyl cellulose blue shades. Specifications 15355/08, [Class 2, Acids and salts, Organic &c.], 268,891, 289,807, and 316,989, [all in Class 2 (iii), Dyes, &c.], are referred to.

Title: Improvements in current regulators
IPC: G05F1/12
Filed: 1962-08-27
Abstract: 970,617. Automatic current control. ZAVODY PRUMYSLOVE AUTOMATISACE, NARODNI PODNIK. Aug. 27,1962 [Aug. 31, 1961], No. 32756/62. Heading G3R. An output transformer 1 is controlled by an error signal from a comparison and amplifying device 8 to provide a constant current to a load 9, e.g. an airport lighting system, which is fed, over a current transformer 6, from the secondary circuit of the transformer 1, a control signal dependent on load current variations being fed to the device 8 over a rectifier 7. It is stated that for systems of this kind the output current tends to drop when the output voltage exceeds 50% of its rated maximum; to compensate for this, a further resistor 4 and a choke 3 are connected as shown to an auxiliary winding 2 of the output transformer, whereby the control signal is modified at higher output voltages. The arrangement is such that the choke 3 saturates at output voltages exceeding 50% of the rated maximum, so that a voltage drop occurs across the resistor 4. This voltage drop opposes the voltage across a resistor 5 connected across the secondary of transformer 6 so that the control signal to the device 8 decreases in value as the output voltage of the system increases. The output error signal from the device 8 is thus increased, and the output from transformer 1 rises to counteract the decrease in load current which would otherwise occur.

Title: A method for the reduction of framing in liquids
IPC: B01D19/02
Filed: 1949-12-21
Abstract: Gaseous and liquid components of a rapidly flowing stream of spumiferous material are separated by passing the stream horizontally into a vessel at a point above the level of the liquid pool collecting therein, and causing the stream to impinge against a mass of filamentous material disposed at a short distance (for example 2-18 inches) in front of the point of entry of the stream; the energy of the stream is dissipated and smaller streams flow down into the pool at lower velocity, so that foaming in the pool is prevented. The filamentous mass may consist of fine corrosion-resistant steel wire, or may be made of tantalum, silica fibre, or plastic material; the proportion of free air space in the mass is preferably at least 80 per cent.  The invention is described with reference to the treatment of high-vis-cosity oil-propane and asphalt-propane mixtures obtained in the removal of asphalt from crude petroleum oil by countercurrent extraction with liquefied propane.

Abstract: 803,650. Powder metallurgy; coating with metals. BIRMINGHAM SMALL ARMS CO., Ltd. Nov. 2, 1956 [Nov. 16, 1955], No. 32786/55. Classes 82(1) and 82(2) A method for producing heat- and corrosion-resistant components having cooling ducts 10, e.g. turbine blades, includes the steps of forming channels 4 in the surface of a solid or powder metallurgy core 2, filling the channels with a temporary solid filling 8, spraying heat- and corrosion-resistant metal over the filled core, removing the temporary filling, e.g. by heating, and sintering the sprayed core to effect diffusion between the sprayed sheath 9 and the core between the channels, so forming a component with an impermeable unitary coating bridging the channels and secured to the core between the channels by diffusion. The sheath may be sprayed to full thickness in one operation followed by sintering, or in several spraying operations each followed by sintering, and an intermediate layer(s) of different material may be sprayed on so long as it will on sintering diffuse into the neighbouring metals. A zinc oxide-zinc filings-mixture with plaster of Paris and borax made into a paste with water is a convenient filler material, though zinc, cadmium, copper, aluminium, or steel wire may also be used. In an example, longitudinal channels.4 are milled in a "Nimonic. 90" (Nimonic is a Registered Trade Mark) core, the core is pre-heated in vacuo to 1250‹C., and cooled, then the channels filled with the zinc oxide paste. The whole is heated to about 200‹C. to harden the paste, after which a layer (optional), of "Colmonoy 6" (Registered Trade Mark) is sprayed, on followed by a sprayed layer of "Nimonic 90" to form a sheath 9. The sprayed core is heated to between 950‹C. and 1250‹C. in vacuo to vaporize the zinc, sinter the sprayed on coating and also cause diffusion between sheath and core, two hours at 1150‹C. being a suitable treatment. The coating may be ground and polished and given a final sintering in vacuo, at 950-1250‹C. Leadsout where the channels 10 come to the surface of the blade may be protected during spraying or the filler may project beyond the core surface. Intermediate sprayed layers of the boride or boroncontaining alloys of Specification 803,649 may be applied. The Provisional Specification refers to core and coating being of the iron base alloys of Specification 746,472.
