Filed: 1972-06-15
Abstract: 1390965 Sizing hollow clay articles HEPWORTH IRON CO Ltd 6 June 1973 [15 June 1972] 28091/72 Heading B5A [Also in Division C7] A mandrel having a co-efficient of expansion greater than fired clay is inserted within a hollow, unfired clay article, and the clay then fired. On cooling, the mandrel shrinks away from the clay to allow removal. As described, undersized steel mandrels 20, 22 are inserted one in each end of a moulded or extruded green clay pipe 10. The clay is heated up to 200‹ C. to reduce its moisture content to 1%, either supported on rings 18, 20 on a kiln car within an associated drying chamber, or on a roller drier conveyer. The clay is then fired at 1040‹ C., and becomes plastic and contracts on to the mandrels as the maximum temperature is reached. The clay is freeze-cooled by blown air to reduce the temperature to 700‹ C., when the mandrels can be removed. The mandrels can be inserted into the pipe at any time up to the clay becoming plastic. An iron/chromium/silicon ferritic alloy is described for the mandrel, having magnetic properties to aid insertion and removal. Spigots, sockets, and plain pipe ends can be sized.

Title: Improvements in or relating to inductor pressure transducers
IPC: G01L9/00
Filed: 1957-09-06
Abstract: 823,323. Differential pressure transducer. EPSTEIN, P. C., and SCHILD, R. Oct. 4, 1957 [Sept. 6, 1957], No. 28262/57. Class 40 (1). A pressure transducer comprises an annular member with a diaphragm of ferromagnetic material extending across it in such a manner that the said member is symmetrically disposed about the plane of the diaphragm, and a pair of similar coil assemblies which are sealed into the space inside the annular member one on each side of the diaphragm and equally spaced therefrom. Fig. 2 shows an annular member 10 formed integrally with a diaphragm 11 disposed between a pair of coils 12 wound on cores 13. The cores 13 are adjacent to end plates 14 which make a fluid seal with the annular member by means of O rings 22. The end plates are secured by means of bolts 25 and the leads to the coils are taken out by means of members 18, 19 and 20. The space between the coils on the diaphragm can be adjusted by placing spacing washers or shims between members 10 and 14. Epoxy resin 26 may be used to fill and seal the remaining unwanted spaces inside. The coils are included in a bridge circuit the unbalance of which is an indication of the differential pressure being applied to the sides of the diaphragm. The annular member 10 and diaphragm 11 are conveniently constructed by hardening and tempering a hollow steel cylinder with an internal plate formed integrally with it and then machining the plate alternatively from either side until a diaphragm of the required thickness is obtained. The symmetry of the device ensures accuracy in measurement of differential pressures substantially independent of temperature and absolute pressure and a high degree of linearity of response.

Title: Improvements in and relating to electronic control circuits
IPC: H03K3/55
Filed: 1951-12-03
Abstract: 692,405. Pulse generating circuits. BRITISH THOMSON-HOUSTON GO., Ltd. Dec. 3, 1951 [Dec. 4, 1950], No. 28281/51. Class 40 (vi). A circuit in which a load is recurrently energized from an electrical storage circuit under control of recurrent signals is protected against overloads due to impedance changes in the load circuit by halting the energization during the occurrence of a predetermined number of the recurrent signals. Fig. 1 shows a circuit for protecting a high-voltage pulse generating circuit against changes in the impedance of the magnetron load 1 caused, for example, by spark-over in the magnetron. Delay line 2 is resonantly charged via inductor 6 from a highvoltage D.C. source 3 and is periodically discharged through the primary winding of transformer 10 when thyratron 4 is fired by the positive triggering pulses applied from lead 7 via valve 8. The high voltage pulse induced in the secondary of transformer 10 energizes the magnetron load circuit 1. If the impedance of circuit 1 falls below normal, a residual negative charge is left on the pulse-forming network 2 at the termination of the discharge period. This voltage builds up after a small number of cycles and is applied from potential divider 18, 19 via diode 20 to hold valve 8 non-conductive during the incidence of a pre-determined number of triggering pulses 7 during which time the instability in the magnetron load circuit is removed until after a period determined by the time constant of resistor-capacitor network 14, 21, valve 8 is rendered conducting by the next triggering pulse and the normal charging, discharging sequence of the circuit is repeated. In a modification shown in Fig. 3 any residual negative charge left in network 2 at the end of the discharge period due to a change in the impedance of the magnetron load 1 induces a voltage in winding 22. The magnitude of the induced voltage is such that at the first cycle of its occurrence valve 8 and thus thyratron 4 are cut-off and are held non-conductive for a predetermined number of triggering cycles.

Title: Metallized azo dyestuffs and process of producing same
IPC: C09B45/01
Filed: 1948-11-01
Abstract: Metallized azo dyestuffs are produced, in substance or on the fibre, from mono- or poly-azo dyes derived from diazotized aromatic amines of the benzene or naphthalene series containing a single ring or two condensed rings and free from substituent groups in o-positions to the azo group, and from hydroxylated coupling components coupling in alkaline solution in o-position to the hydroxy group, by heating such dyestuffs in an alkaline solution with a copper salt and a peroxidic oxidizing agent (e.g. a per salt of a low molecular weight fatty acid).  In examples: (1) the diazo dyestuff aniline (2 mols.)\sQJ-acid urea is heated with an aqueous solution of copper sulphate, per-formic acid and sodium carbonate; (2) the dyestuff m-acetylaminoaniline (2 mols.)\sQJ-acid urea (hydrolysed), is dyed on cotton, diazotized on the fibre and developed with b -naphthol, after which hydrogen peroxide and copper sulphate are added to the developer bath, which is then heated.  The following additional components are specified (and some of them employed in the production of further mono- and poly-azo dyestuffs listed as starting materials): diazo components: m- and p-nitraniline, N-acetyl-p-phenylenediamine, m-amino-o-cresol ethyl ether, p-aminophenol, sulphanilic acid, p-toluidine, m-chloraniline, b -naphthylamine and 2-naphthylamine-5- and 6-sulphonic acids; coupling components: b -resorcylic acid, b ,naphthol, 1-naphthol-4- and 5-sulphonic and 3 : 6- and 4 : 7-disulphonic acids, H-acid and is acetyl and benzoyl deriratives G-, K- and R-acids, Schaeffer's acid, 2 - naphthol - 3 : 6 : 8 - trisulphonic acid, b -hydroxynaphthoic acid, 1 - phenyl - 3 - methyl-5 - pyrazolone and 1 - p - sulphophenyl - 3-carboxy-5-pyrazolone. Other suitable oxidizing agents are sodium perborate, ammonium perphosphate, and per-propionic, per-butyric and per-benzoic acids.  The Specification as open to inspection under Sect. 91 comprises also the production of complex compounds of metals other than copper (e.g. nickel, cobalt or chromium), the treatment of dyes derived from other diazotized amines of the benzene or naphthaline series free from substituents in o-positions to the azo group (e.g. benzidine), and references to the use, as coupling components, of naphthionic acid (sic) and dichlorbenzoyl-K-acid. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-06-14
Abstract: 1471527 Monitoring particle suspensions COULTER ELECTRONICS Ltd 7 June 1974 [14 June 1973] 28350/73 Heading G1N [Also in Division F2] In the on-line testing of a flow of a fluid particle suspension using a Coulter type analyzing apparatus the flow of fluid is maintained constant. Filtered sea water to be tested flowing along pipe 12 is sampled by tube 16 connected by flow restrictor 20 to a flow-through sampling chamber 42 in which are mounted apertured tubes 26, 28, 30 and associated electrodes 44 and 32, 34, 36 for monitoring the particle sizes. To make the differential pressure at each aperture 26a, 28a, 30a constant to ensure the same volume of fluid passing through the apertures in a predetermined time a regulator 56 is coupled to the chamber 42 which comprises two hollow members 62, 64. Member 64 of greater cross-section train member 62 is filled with mercury whereas member 62 is filled with the less dense test fluid. Initially with low or atmospheric pressure in member 62 the mercury falls to the base of the U-tube with the two surfaces at the same level. If now the pressure in  member 62 increases, due to an increase in pressure in chamber 42 the mercury column is driven up into member 64 until a point is reached where the boundary surface of the mercury and test fluid is at 66. Any further increase of pressure of the test fluid does not cause the base of the mercury column to rise but causes the test fluid to breath through the lower boundary surface and rise through the mercury column to relieve the pressure of the test fluid. Thus the pressure within chamber 42 remains constant. A U-tube manometer 73 may be provided to indicate the pressure due to the head of mercury in regulator 56. If the pressure within the main pipe 12 falls below a minimum pressure a pump 76 can be provided to produce the pressure. Particle analyzer. Debris detecting and clearing circuit 82 of the type described in Specification 1061776 may be used. If a blockage occurs in one of the aperture tubes a signal is fed to control apparatus 52 to initiate a debris clearing procedure e.g. by pinching conduit 46 to create a back pressure at the aperture of the tube. If this is unseccessful the tube is disengaged and another tube is used instead. When blockage occurs circuit 82 applies an inhibit signal to line 85 to inhibit pulses from being registered in output 86. This latter may have a pre-setable pulse count value stored in it such that if this is exceeded alarm 88 is actuated.

Abstract: 834,494. Frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. July 1, 1958 [Sept. 9, 1957], No. 28369/57. Class 37. [Also in Group XL (c)] A device for ascertaining the frequency of a signal comprises a plurality of resonators C1-Cn having different resonant frequencies covering a band; a leaky condenser circuit K, R; a plurality of rectifiers D1-Dn connected each between one side of condenser K and one side of a resonator; a plurality of output circuits L1-Ln each fed from a different resonator; means such as amplifiers 2, 3 and transformers T1-Tn for feeding input signals to all the resonators; and means arranged to connect the output circuits in two groups, neither of which contains the output circuit of the resonator which is predominantly responsive to the signal. In a preferred device the resonators have the same Q value, their resonant frequencies are spaced logarithmically over the band, and the output resistors 2R1-2Rn are replaced by germanium diodes. The resonator which is most responsive to the input signal feeds pulses of current, through its rectifier, to condenser K, the potential across which builds up and backs off the remaining rectifiers. Movable contactors CT1, CT2 are connected to fixed contactors CT3, CT4 by brushes B1, B2, respectively, and CT3, CT4 are connected through bistable circuits 5, 6 to a reversing relay switch 7 controlling the polarity of the supply to motor 8. This motor thus rotates CT1, CT2 until neither is connected to the responsive resonator output circuit. Motor 8 also drives wiper 11 of potentiometer 12 in such a manner that phonic wheel generator 14 produces an output frequency corresponding to the signal frequency.
