Title: Preparation of high molecular weight aromatic polyamines
Inventor: HEYDKAMP WOLFGANG
IPC: C08G59/50
Filed: 1968-04-09
Abstract: 1,217,735. Aminated polymers. FARBENFABRIKEN BAYER A.G. 9 April, 1968 [18 April, 1967], No. 17021/68. Headings C3B and C3R. Polyamino compounds are prepared from polynitro compounds of the formula where R is a bifunctional aryl radical which may be substituted by halogen, alkyl or hydroxyalkyl, x is 1 to 3 and G is a bifunctional organic radical obtained by removal of terminal OH groups from polyethers, polythioethers, polyesters, polycarbonates of polyacetals, which polymers may be extended with polyisocyanates. The conversion to amines is effected with hydrogen in the presence of a nickel carrier catalyst, the nitro compound being dissolved in a solvent which is substantially immiscible with water, the pH being adjusted to 5À9 to 7À2, and the quotient of the weight of water produced to the weight of solvent being from 0À03 to 0À05. The polymers from which G is derived have a molecular weight of 500 to 5800 and 2 to 4 OH groups in the molecule. The polyethers include polyalkylene glycols, alkylene oxide adducts of tri- and higher polyhydric compounds, and condensation products of glycols and sulphurcontaining glycols. The polyesters include condensation products of glycols with dibasic acids. The polyacetals may be condensation products of glycols and of dihydroxy aromatic compounds with aldehydes. All these polymers are converted to the compounds of Formula I by reaction with nitroarylisocyanates. The polynitro compounds may be dissolved in, for example, chlorobenzenes, and the pH adjusted by alkaline materials. Hydrogenation is preferably carried out at 20-140‹ C. The polyamino products may be converted to polyurethane-polyurea resins, or may be used for hardening epoxy resins or for reacting with diisocyanates to yield lacquers. Reference has been directed by the Comptroller to Specification 1,104,209.

Title: Improvements in or relating to prime movers using exhaust steam
IPC: F01K7/02
Filed: 1929-06-04
Abstract: 313,053. Aktiebolaget G÷taverken. June 5, 1928, [Convention date]. Compound &c. engines.-Exhaust steam from a multiple-expansion reciprocating-engine is conducted wholly or in part to a turbine 8 driving a multiple-stage compressor, the various stages 12, 13 of which compress steam taken from the outlets, receivers or cylinders and supply it to the admission sides of the cylinders. Alternatively air may be compressed and used in a cylinder arranged tandem to one of the power cylinders. The compressor cylinders deal with steam from the second and last stage 3, 4 of the engine. The steam discharged from cylinder 13 may pass to the receiver 6, or to the high pressure supply 5. The low-pressure cylinder exhaust may pass to the condenser 10 past a valve 24<1>. The additional power developed may be used in the main cylinders by using a later cutoff, or by increasing their strokes, or in auxiliary tandem-cylinders. The dimensions of the compressor cylinders may be reduced by supplying them with the initial exhaust steam at the release pressure 23, Fig. 3. This may be taken from the turbine supply through a non-return 24 which leads it to a reservoir 25, or steam may be taken from the cylinder at a point corresponding to 27, Fig. 3, past a non-return valve and supplied to the reservoir. Steam may be taken from the receivers through conduits 20, 21, 22 to feed-water preheaters 19. In a modification, the steam is taken to the stages of a turbo-compressor after passing through the first and second stages of the engine respectively. The high-pressure compressed steam is superheated and supplied to the supply main 5. In a further modification, the compressor supplies air to auxiliary tandem power-cylinders.

Title: Improvements in and relating to apparatus for gauging a conductive solid object
Inventor: DAVIES WESLEY MORLEY
IPC: G01B7/00
Filed: 1963-06-01
Abstract: 1,101,581. Measuring linear dimensions electrically. STEEL CO. OF WALES Ltd. Aug. 24, 1964 [June 1, 1963], No.17205/63. Heading G1N. The position or a dimension, of an object such as the width C 1  C 2  of a steel strip passing over a roller 2, Fig. 3, is measured by traversing a jet of fluid Y 1  from a probe F 1  across the object, passing a current I 1  from the probe to the object through the fluid, and sensing the break in this current when the jet reaches the edge of the object. The current flows in a circuit comprising a battery 40, an electrical connection to the fluid at a, the jet Y 1 , the object with its roller and supporting frame Z, and a detector 42, the frame being earthed and the fluid supply pipes 20, 21, forming an impedance to earth, represented by R2 (equivalent circuit given in Fig. 4, not shown). The probe itself is heat resistant, and electrically insulated from the fluid supply pipes except via the fluid itself, Fig. 2 (not shown). The probe is driven across the object under test by a motor (7), Fig. 1 (not shown), which also rotates a slotted disc (14) between a lamp (16) and a photo-electric cell (17) to indicate in pulse form the extent of travel of the probe, the width of the object C 1  C 2  being indicated by the number of pulses counted between the start and stopping of current flow in the fluid jet, Fig. 7 (not shown). Errors due to the current being cut off by impurities on the surface of the object are avoided by provision of a second jet which scours the surface, and also by including in the measuring circuits a delay device which prevents the pulse count being stopped by a short duration break in the current. Further arrangements referred to for measuring dimensions such as width or thickness include: a plurality of fixed jets arranged to be sequentially operated to effect a scanning motion; a localized scan with respect to only the edges of the object being measured; and a servoscanning arrangement in which a probe follows each edge either closely, or with a hunting motion across the edge.

Title: Glass compositions exhibiting phototropic properties
IPC: C03C4/06
Filed: 1964-04-27
Abstract: A phototropic silicate glass article comprises in at least a portion thereof crystals of at least one metal halide wherein the metal is Cu or Cd and the halogen is Cl, Br or I. The said portion contains by weight a total of 0.3-10% of Cu and/or Cd, and sufficient Cl and/or Br and/or I to react stoichiometrically with at least the 0.3% minimum total of Cu and/or Cd; in either the metal or the halogen may be in stoichiometric excess.  As well as the above constituents, the glass composition may comprise, in per cent by weight, SiO2, 40-76; Al2O3, 4-26; B2O3, 4-26; at least one alkali oxide selected from: Li2O, 2-8; Na2O, 4-15; K2O, 6-20; Rb2O, 8-25; Cs2O, 10-30; the total weight of the above-specified constituents being at least 85% of the total glass composition. Other constituents that may be present are F, e.g. up to 1-5%; and reducing agents, generally less than 1%, e.g. SuO, FeO, As2O3, Sb2O3, or sugar. The crystals may be formed by cooling the melt to a glass body, the temperature being held for a sufficient time at the treatment temperature after which the body is cooled to room temperature; or by quenching followed by exposing to the treatment temperature, which is above the strain point, i.e. 450-475 DEG  C. and below 950 DEG  C., followed by cooling. Alternatively, if the body is held at the strain point for 16-24 hours, satisfactory crystallization occurs. Specification 950,906 is referred to.

IPC: H01F6/00
Filed: 1965-04-23
Abstract: 1,088,172. Superconductor structures. SIEMENS-SCHUCKERTWERKE A.G. April 23, 1965 [April 23, 1964], No. 17366/65. Heading H1K. A magnetic screen consists of a hard superconductor in which is distributed a number of discrete layers of bodies of a non-auperconductor of good thermal conductivity, the latter being included to improve dissipation from the screen of heat arising from flux jumping. The screen may comprise hot-pressed interleaved sheets of superconductor and non-superconductor and may have the non-superconductor projecting beyond the other sheets to act as fins to dissipate heat to a cooling medium. The non-superconductor may be slotted to reduce eddy currents. In other forms the screen may form the outer structure of flux pumps of the types having two parallel bores-these may be separated or may partially coalesce. As an alternative to interleaved sheets, the screen may be in the form of a sintered mass of superconductor the interstices of which are filled with the non-superconductor. In a further variant the non- superconductor takes the form of pipes within the superconductor. Liquid helium is passed through the pipes to cool the screen. Suitable superconductors are alloys of niobium-zirconium and niobium-titanium, and compounds of niobium-tin, vanadium-gallium, and vanadium silicon. Suitable non - superconductors are copper and gold. The screens may be given an outer coating of a non-superconductor by vapour coating or electrolytic deposition.

Title: Improvements in or relating to benzene hexachloride
Inventor: JR ARTHUR CHARLES ELLSWORTH
IPC: C07C23/12
Filed: 1955-06-16
Abstract: Benzene hexachloride enriched in gamma isomer is made by additively chlorinating benzene in the liquid phase at a temperature not exceeding 70 DEG  C. until a slurry is formed, in which at least 80 per cent by weight of the gamma isomer is in the liquid phase, raising the temperature to dissolve at least 2 per cent by weight of the solid phase, cooling at a rate not in excess of 12 DEG  C. per hour, preferably at a rate between 2 DEG  C. and 12 DEG  C. per hour, to reprecipitate dissolved solids, but not beyond the point at which 20 per cent by weight of gamma isomer will precipitate, removing the solid phase from the cooled slurry, e.g. by centrifuging, and recovering gamma enriched benzene hexachloride from the liquid phase. In an example, benzene is chlorinated at 24-25 DEG  C. under irradiation with actinic light, at the conclusion of the chlorine addition the temperature of the reaction slurry is allowed to rise to 51.5 DEG  C., after 1-2 hours at this temperature the mixture is cooled to 15-19 DEG  C. over a period of 4-7 hours, the solids are removed by centrifuging and the gamma enriched fraction is recovered from the liquid phase by distilling off the benzene.

Abstract: 896,087. Automatic temperature-control systems. SYLVANIA-THORN COLOUR TELEVISION LABORATORIES Ltd. May 11, 1960 [May 21, 1959], No. 17395/59. Class 38 (4). A temperature-control circuit comprises a PNP and an NPN transistor having their emitter-collector paths in series between two supply terminals, two impedance elements in the respective emitter-collector circuits, one being temperature-dependent, and an output circuit, connected to the junction of the two emitter-collector paths, including means for varying the temperature of the medium in which the temperature-dependent resistor is located so as to maintain the temperature at a predetermined value. As described, PNP transistor 10, and NPN transistor 11, Fig. 1, are connected in series opposition across the power supply terminals 13, 15, with their collectors connected to a common emitter stage 20. A thermistor 14, and a variable resistor 12 are connected in the emitter circuits of transistors 10, 11, respectively, so that variations in resistance of the thermistor will produce a variation in the output at terminal 24. The thermistor is placed in a medium to be maintained at a predetermined temperature, and resistor 12 adjusted to make it equal to the thermistor resistance at the required temperature, When the medium is not at the required temperature the standing currents of the transistors are unbalanced, producing an output signal which is used to switch on a means for heating or cooling the medium as required. Other temperature-sensitive devices, such as platinum wire, may be used in place of the thermistor. In a suitable control circuit. Fig. 2, the output from the amplifier is fed into the base of one transistor 25 of a cross-coupled pair, the output from which is applied to the base of a further transistor 33 which has in its collector circuit a relay 32 controlling the heat source.

Abstract: 108,620. Gill, H. A., (United States Light & Heat Corporation). Dec. 5, 1916. Exciting; dynamos, driving; motors, gearing for; machines with two or more armatures.-A dynamo-electric machine particularly adapted for engine starting and battery charging comprises two armatures 3, 4, Fig. 1, which act together while motoring and only one of which operates under generating conditions. The machine is excited by series field windings 13, 14 and by shunt field windings 10. The connexions for motoring are shown in Fig. 7, the armature 4 being connected directly across the battery 25, and the armature 3 being connected across the battery through the series windings 13, 14 connected in parallel. When the engine has started up and the switch 41 is released, the armature 3 is disconnected and the series field windings 13, 14 are connected in series with the battery 25 and armature 4 which is now generating. The flux produced by the series winding 14 is in opposition to that produced by the shunt windings 10 when the armature 4 is generating and assists it when motoring. The fluxes in the armatures 4, 3 assist each other both when the machine is motoring and when it is generating. The fluxes in the two armatures are in opposite directions so that the armatures may be directly geared together, an overrunning clutch being provided to interrupt the transmission mechanism when the engine drives the generator armature. The armature 3 is wound with a small number of low resistance conductors and the armature 4 with a large number of high resistance conductors, and the gearing gives a speed ratio inversely proportional to the numbers of conductors in the armatures. In a modification, the series field windings 63, Fig. 12, are provided on intermediate pole-pieces 56, and a series field winding 64 and shunt field winding 65 on an end pole-piece. Separate switches 74, 75 are provided to effect the motoring and generating connexions respectively. The shunt winding 65 may be connected directly across the armature 59. In a modification of the gearing, the armature 82, Fig. 13, instead of being geared to the armature 83 directly, is geared to the fly-wheel 88 of the engine through a screw-threaded shaft 86 and pinion 87, or any other form of Bendix drive, the armature 83 being connected to the crank-shaft 89 through chain gearing 95. In place of the Bendix drive, the pinion 87 may be controlled directly from the starting-switch.
