Filed: 1963-12-31
Abstract: 1,098,903. Magnetic amplifiers. G.E.C. ROAD SIGNALS Ltd., P. J. BARKER, E. GARDNER and S. D. POOL. Dec. 22, 1964 [Dec. 31, 1963], No. 51370/63. Heading H3B. A magnetic amplifier of the second harmonic type comprises two cores 5, 6 of which one has three limbs, a plurality of control windings being arranged on the centre limb of the three limbed core. In addition, the amplifier has an operational threshold and provides an output to a load 13 only when the control energization exceeds a threshold value. As shown in Fig. 4, the amplifier has an A.C. input winding 10 of resistance wire coupled to both cores and parallel output winding portions 9A, 9B, each in series with a rectifier 14 also coupled to both cores, the primary input and secondary output windings being so arranged that no resultant output is produced across either output winding portion in the absence of control energization. Two separate control windings 16 are associated with the centre limb 3 of core 6 and enable the amplifier to operate as an OR gate. A shortcircuited turn 12 on the central limb suppresses alternating flux which would otherwise induce A.C. in the control windings and raises the threshold level. The amplifier cores and preformed windings are supported on plastics bobbins 18, Figs. 5 and 6 (not shown), each consisting of a flat end cheek 19 from which extend moulded open-ended tube portions 20. The cores are formed by laminations which are inserted through slots 22 in the outside of the bobbin cheeks 19. For maintaining the input current constant in the event of a partial short-circuit of the winding 10, an inductor may be connected in series which may have its core added to the basic assembly, the winding 10 being extended to embrace this core.

Title: Process for dissolving metals
IPC: C23F1/18
Filed: 1964-12-22
Abstract: A solvent for metals for use in etching printed circuits or other dissolving operations such as chemical milling or polishing, comprises an acidified aqueous solution of hydrogen peroxide to which has been added a catalytic amount of phenacetin or sulphathiazole or silver ions or mixtures thereof.  When phenacetin is used alone, the solvent must contain less than 2 parts per million by weight of free chloride or bromide ions.  The solution contains 2%-12% by weight of hydrogen peroxide and 2%-23% by weight of sulphuric acid. Other acids such as acetic acid, nitric acid or fluoboric acid may be employed. Salts yielding the additives in the acid-peroxide solution may be employed e.g. the sodium salt of sulphathiazole, silver nitrate, silver sulphate. If water containing excessive amounts of chloride and bromide ions is used in the solvent, suitable material such as a water soluble silver salt is added to remove the free chloride and bromide ions. Acid may be added during the use of the solution to keep the concentration at the required amount.  Etching is carried out at a temperature of 40 DEG C.-65 DEG C.  The solvent may be used for etching copper, iron, nickel, cadmium, zinc, germanium, lead, steel and aluminium and alloys thereof.

Agricultural crop is fed into the body of a trailer vehicle by tines 82 and 93. The tines 82 form part of a pick-up drum which is pivotally suspended and which raises the crop into engagement with the tines 93 whose tips move along a path 160. During this movement the crop is guided by four tubes 125 which are also adjustable for height. Ground wheels 56 may be raised or lowered by a lever 65 and vertical positioning of the pick-up drum may thus be adjusted. A castor wheel 14 permits the level of the forward end of the trailer to be adjusted. The floor of the body comprises endless chains 130 having slats 131, the chains being intermittently driven by pawl and ratchet means, Fig. 5, (not shown). To unload the body, its rear wall, which is pivotally mounted at its upper edge, is swung outwardly by linkage actuated by a lever 42. The endless chains then push the crop out of the body. The pick-up drum, the tines 93 and the endless chains 130 are all driven from a power-take-off shaft 105.

Abstract: 1368647 Insulating coatings on electrical conductors WESTERN ELECTRIC CO Inc 23 Nov 1971 [24 Nov 1970] 54300/71 Heading B2E [Also in Division H1] An electrical conductor, e.g. copper wire, has an insulating layer comprising wood pulp mixed with polyethylene or polypropylene fibres, the fibres being present in an amount of 10% to 90% by weight, said fibres being from 1.5 to 6 denier and from 1/16 to 3/4 inch long. A slurry of wood pulp and polyolefin fibres which were previously washed in stilled water is container in a hopper of a Fourdrinier machine which converts the slurry, which may contain a surfactant, into a ribbon and winds the ribbon onto the conductor in the form of a copper wire bundle. The winding is then polished. The polyolefin may be polyethylene in which case a binder may be included which may be a branched polyethylene powder added to the slurry and the ribbon sheets are bonded under heat and pressure to melt the binder but not the fibres. Alternatively the polyolefin is polypropylene in which case the fibres are coated with a dispersing agent which is also present in solution in the slurry. The binder is then sprayed or rolled onto the insulated wire and may comprise a cross-linked latex copolmer, an acrylic latex or a styrene-butadiene coplymer emulsion, or an emulsion or powder of branched polyethylene such as "Microthene" (R.T.M.) or amorphous polypropylene. The binder may alternatively be added to the slurry before formation of the insulating layer on the wire. The binder improves the electrical dielectric constant and dissipation factor for telephone wires and several graphs (not shown) illustrate the variation of these properties with the varying composition of the insulating material.
