Patent GB-856584-A (GB)
Title: Improvements in or relating to composite electrical components and methods of manufacturing same
IPC: H01B3/00
Filed: 1957-03-05
Abstract: <PICT:0856584/III/1> <PICT:0856584/III/2> <PICT:0856584/III/3> <PICT:0856584/III/4> An electrical component such as a capacitor, comprises alternately deposited layers of conductive and non-conductive material, contact being made with the conductive layers by means of conductive leads extending into the body of the component and bonded to the conductive layers.  In a preferred embodiment, Fig. 1, the layers are deposited in semi-liquid form upon a base member 100, the insulating layers 21 comprising a finely ground ceramic or enamel frit in a suitable liquid carrier and the conducting layers 22, 23 comprising a silver paint.  Each layer is allowed partially to harden before the next layer is deposited so that a rigid but plastic body is obtained.  Cavities comprising well portions 25 with intervening shallower portions are then formed at appropriate positions with respect to the conducting layers 22, 23. The walls of the well portions 25 are coated with some of the silver paint and also, if desired, with some of the ceramic composition to prevent "migration" of the silver.  Leads 26, Fig. 5, are then inserted into the wells 25.  The composite body is then cut along lines 50 to form individual capacitors as shown in Fig. 5; these are then subjected to a comparatively low temperature drying process and then fired to convert each capacitor unit to a solidly bonded monolithic structure.  The leads 26 are not bonded to the structure throughout the whole length of the recesses 24 and hence may be bent forward as indicated at 261.  Fig. 8 illustrates an alternative way in which successive conductive layers may be connected together.  The insulating layer 154 deposited after the conducting layer 153 is pierced to expose the layer 153.  Then on depositing layer 156, the aperture thus formed is filled to provide a plug 155 interconnecting the layers 153 and 156.  Fig. 9 shows this technique applied to the constrution of a capacitor.  Alternate conducting layers 162 are connected together as shown in Fig. 8. An aperture is then formed through all the conducting plugs and a lead 168 inserted before the firing step is carried out.  The lead 164 connected to the other conducting layers 163 is inserted into the body by a further alternative process, i.e. by forcing it through the comparatively soft material of the body before it is fired.  The preferred compositions for the ceramic composition and silver paint are given. It is stated that the insulating material may alternatively comprise synthetic resinous insulating materials such as partially condensed phenolformaldehyde resins, partially polymerized vinyl resins, mixtures of acrylic monomers and polymers and suspensions of nylon tetrafluoroethylene and polystyrene.  The conducting layers may instead be composed of gold, rhodium palladium or platinum. Specification 851,406 is referred to.

Abstract: 702,904. Feeding webs. FIRESTONE TIRE & RUBBER CO. March 23, 1950 [June 8, 1949], No. 7290/50. Class 100 (1). [Also in Group VIII] Apparatus for forming rubberized fabric comprisse a rubber calender having two rolls into the bite of which is fed a web of fabric and a layer of rubber to be applied thereto, a tension roll over which the web is passed prior to entering the bite of the rolls and a generator of electric current driven by the shaft of the tension roll to create a resistance to motion of the roll. The web may be taken from either of the positions 60 or 61 and is guided to the tension roll 13 over idler rolls 11 and 12. A regenerative motor 14 is connected to the shaft of tension roll 13. Rubber is applied to one surface of the web in a three bowl calender 15, 16 and 17 and after being guided over suitable idler rolls and a second tension roller 32 which drives a regenerative motor 33 the web receives an application of rubber on the other side in a calender 34, 35, 36. A roll 22 receives a force applied by the tension in the web which is balanced by the force on pistons in the compressed air cylinders 25 and 26. The roll 22 is connected to a rheostat controlling the motors driving the two calenders so that any change in position of the roll 22 is reflected in changes in calender speed. After passing a bank of drier rolls 40, 45, the first of which, 40, is driven, the web passes over a driven roll 48 and is reeled up at either of the positions 50 or 54 by the aid of motors 51 and 55. Fig. 8 illustrates the circuit arrangement for the regenerative motor 14. A tachometer generator 83 coupled to the calender motor excites the field of an auxiliary generator 81 which is in series with the armature of the regenerative motor 14 together with a power contactor M, a thermal overload protective device OL and a booster generator 80. The regenerative motor shunt field is in series with a fixed resistance across a constant potential excitation system, as is the booster generator shunt field 85, the latter being in series with a rheostat 86 which may be hand or automatically controlled.

Title: Improvements in the manufacture of steel by the basic bessemer process
IPC: C21C7/10
Filed: 1945-03-23
Abstract: In a process for the manufacture of basic Bessemer steel, the molten steel made by the ordinary basic Bessemer process is subjected in the converter or other vessel to a vacuum, for such a time, depending on the negative pressure and on whether there is gas evolution or not, that substantially the whole of the injurious active nitrogen is removed, the time without gas evolution being 5 minutes at 10 mms. 16 minutes at 100 mms. or 3 minutes at 1 mm. of mercury.  A carbon monoxide boil may be instituted when the time is reduced to 10 minutes at 100 mms. of mercury.  The negative pressure may be applied to the metal in the ladle, in a mould during solidification, or to re-melted metal by the fitting of an air-tight cover to the vessel. The process may be applied in conjunction with the processes described in Specifications 493,610 and 518,212.  Specifications 30198/10, [Class 29], 131,372, 226,738, [both in Class 72], and 591,841 also are referred to.

Title: Improvements in or relating to communication systems
IPC: H02J13/00
Filed: 1958-03-10
Abstract: 883,688. Signalling over power lines. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 10, 1958 [March 11, 1957], No. 7629/58. Class 40 (4). In a system for signalling over power lines a high frequency is fed to the line at a first point and means for modulating this frequency is provided at a second point, detection of the modulation taking place at a third point which may be the same as the first. As shown, Fig. 1, a 3510 c.p.s. current is injected into the line, the injection taking place in the first instance according to a predetermined time code to select a specific station on the line. When the appropriate station's code responsive device is operated it connects up and may initiate the operation of an associated device 5. The latter controls a device 17 which operates to vary the tuning of a shuntconnected tuned circuit 14, 13, 12 at a predetermined frequency, e.g. 17 c.p.s. The resulting amplitude or phase modulation (for different positions of detector and modulator one or other may be the more marked-according to the loading of the mains circuit at the time) may be observed by an amplitude modulation detector 20 (which may comprise a circuit sharply tuned to one of the side bands) or a phase-modulation detector 31 or both. If the detector is at the same point as the source, variation of the current through the latter may be observed. Alternatively, amplitude modulated voltages tapped off the lines may be rectified, the resulting 17 c.p.s. component being further amplified and used to fire a gas tube having an anode relay, Fig. 6 (not shown). In this circuit the amplitude modulation detector may be replaced by a phase-modulation detector, Fig. 7 (not shown). In the latter instance the modulation device should not be connected to all phases of the mains supply, one of these being reserved for a reference current for phase comparison. The modulation device shown comprises a toothed wheel 16 arranged to vary the flux through a winding 12 in the tuned circuit whose tuning is thereby varied. Alternatively, a relay vibrating at 17 c.p.s. could intermittently shortcircuit a resistance in a timed circuit. Fig. 3 illustrates a further form of variable inductance comprising a coil 29 whose inductance varies according to whether or not the stationary teeth 28 and the rotating teeth 27 are opposed. Specifications 694,110, 753,753 and 772,307 are referred to.

Abstract: 996,884. Retort furnaces; supplying liquid fuel burners. FETOK G.m.b.H. Feb. 28, 1962 [March 2, 1961], No. 7825/62. Headings F4B and F4T. A retort furnace having oil burners located in combustion chambers arranged at the sides of the retort is heated in a heating-up period by combustion of atomized oil and thereafter by combustion of an oil spray. Oil is supplied by a pump 5 from a tank 7 through conduit 4 to an oil burner 2 located in a combustion chamber 1. Normal operation of the burner 2 gives a spray of oil. An electrical heating coil 3, arranged about the conduit 4 may be used to preheat the oil so strongly that the burner 2 discharges the oil in atomized form. An oilwater mixture may be employed for this purpose also, water being introduced through line 10. In this case the mixture is heated to above 100‹ C. so that the steam generated acts as a carrier for the fine oil particles. The method of heating may be modified in that the discharge of oil either in atomized or spray form may be carried out intermittently.

Title: Active dried yeast
Inventor: TREVELYAN WILLIAM EDWARD
IPC: C12N1/04
Filed: 1967-02-18
Abstract: 1,140,016. Drying yeast; yeast and flour mixtures. DISTILLERS CO. (YEAST) Ltd. 15 Dec., 1967 [18 Feb., 1967], No. 7861/67. Headings A2B and A2D. [Also in Division C6] An active dried yeast is produced by disintegrating yeast containing from 27% to 40% of dry matter in such a way as to give a mass of yeast particles in which the yeast cells themselves are not broken down and in which the mass of particles has a volume/weight ratio which is greater than that of the product before disintegration, and thereafter dry the product resulting from the disintegration step to a dry matter content of about 92% by weight without any mechanical mixing or the application of pressure on the yeast. The disintegration is effected by means of sharp rotating blades e.g. laboratory macerator running at 10,000 r.p.m. for 5-15 seconds, wire beaters or vibrating screens, and the volume to weight ratio after disintegration is typically about 2.7 times that before disintegration. The drying is carried out in an air recirculation system using air at temperatures between 20 and 60C., a circulation rate of from 50 to 400 litres of air per minute per kilogram of yeast and a relative humidity of between 45 and 30%. The active dried yeast produced is fragmented in a macerator and then screened through a B.S. No. 30 mesh sieve to give a coarse fraction suitable for the same range of uses as commercially available active dried yeast and a fine fraction that can be automatically metered, directly mixed with flour or incorporated with specially dry flour for use in making complete mixtures for home-baking. The fine fraction can readily be dried to a dry matter content of about 95-96% by weight and has enhanced stability on storage at elevated temperatures; it should, however, be exposed for some time to an atmosphere of controlled humidity, e.g. about 33% at 20C., before reconstitution. Alternatively, it can be mixed with an excess of flour, which as used for baking usually has a water content of about 13-15%, whereupon a slow rehydration occurs by the interchange of water between the flour and the yeast. Mention is made of storing the yeast at 40C. in air or nitrogen.
