Title: Improvements in bonding metal oxide bodies to metal bodies
IPC: H01B1/00
Filed: 1961-01-04
Abstract: The invention provides a composition for metallizing the surface of metal oxide bodies which are to be soldered to metal bodies such as copper wires, to form joints of low electrical resistance.  The composition consists of finely-divided iron particles of not larger than 100 American Standard Mesh, glass particles of a size smaller than that of the iron particles and which are fusible at a temperature of 650 DEG  to 800 DEG  C., and a material having a solvent action on the metal oxide surface.  The only example of a material having such a solvent action is aqueous ammonia.  The particular glass type is not important.  For example, sodium, potassium, and lead glasses each having an appreciable silica content are suitable as is silica itself and particularly silica gel. Silver, gold, or platinum particles may be added to the composition in appreciable quantities to facilitate soldering further.  The invention also provides methods of joining metal-oxide bodies to metal bodies in which the oxide bodies are coated with the metallizing composition, fired, and soldered to the metal bodies by known methods. Suitable solders are lead/tin, lead/tin/antimony, and lead/silver alloys. If desired, either before or after firing, the metallizing composition to the oxide body, the surface of the coating can be covered with a metal paint (for example, containing gold, silver, or platinum) prior to the soldering operation.  The oxide body when coated with paint after firing may be refined before soldering.  Many metal oxide materials are mentioned including the positive temperature coefficient resistive materials described in Specification 956,579.  All the materials mentioned include one or more of zinc, iron, nickel, cobalt, copper, manganese, and titanium.

Title: Improvements in or relating to reinforced concrete constructions
IPC: E01D19/14
Filed: 1953-01-08
Abstract: 747,966. Roofs; bridges. WILLIAMS, Sir E. 0., and WILLIAMS, 0. T. Dec. 23, 1953 [Jan. 8, 1953], No. 642/53. Classes 20(1) and 20(4). In the construction of roofs, bridges or other spanning structures, the structure is built out from a pier or column, without support from below, progressively in sections which are tied to the pier by tensioned members which are subsequently encased in concrete. Fig. 1 shows one half of a bridge construction which includes two concrete piers 20 each having an anchor span 21, a central span being suspended between the piers. Pairs of strut towers 25 are erected on each pier 20 ; there may be one pair only, or one pair for the " up " road and one pair for the " down " road may be provided. The towers are spaced by bracing 19. The road deck of the anchor span 21 is first moulded in sections, e.g., each about 15 feet of road length, each section being connected by tension members 28-33 to the towers 25. A temporary staging 22 facilitates the construction of the anchor span. The suspended span is now cast in sections, beginning from the towers, each section being cast in a mould 40 which is supported on bogies 42 and is cantilevered out from a previously moulded section 38. It is anchored at 43 to another section 36. During the casting, each section is attached by its ties 45-49 to the tops of the towers 25, the tensioning of the respective ties being effected when the mould 40 is in use for the next section. The degree of tension may be determined to accord with maximum working load by adjustment of the positions of the anchor points 43. Whilst the ties are thus tensioned, they are concreted. The shore end of the anchor span is connected, in normal manner, to a counterweight 18 to prevent compressive stresses in the back stay 33. The ties 29-33 are finally con;, creted. Stiffening or distributing girders 50 and a rail 44, extending along each side of the carriage way, are constructed after the moulding of the deck sections, the girders 50 enclosing the anchorage points of the ties. Vertical bracing members 39 are provided at intervals. In a modification, Fig. 8, a bridge is built by casting sections, step-by-step symmetrically out from each pier 70, the sections, as before, being provided with ties connecting them to the tops of the towers. The spans are made alternately continuous, as at 71, and non-continuous with short links 72.

Title: Improvements in electric transformers
Inventor: HARMER JOHN DAVID
IPC: H01F38/08
Filed: 1953-01-12
Abstract: 748,883. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 1, 1954 [Jan. 12, 1953], No. 866/53. Class 38 (2). An adjustable ratio transformer comprises an annular magnetic core having a primary winding 1 toroidally wound and uniformly distributed thereon, has one or more auxiliary windings-such as 4 or 7-also toroidally wound thereon, each auxiliary winding being uniformly distributed over or under a section of the primary winding possessing the same number of turns as does the auxiliary winding. As shown, one auxiliary winding 4 is wound, in opposite sense, over the primary winding 1 from the mid-point 5 to the finishing end 3 thereof. The auxiliary winding 4 is, however, electrically connected between the mid-point 5 and the other or starting end 2 of the primary winding 1. Similarly another auxiliary winding 7 is wound to occupy a quarter of the primary winding 1 but is connected across a different quarter thereof. Thus if an input is applied at terminals 2, 3, a stepdown ratio of one half or one quarter will be obtained at terminals 2, 5 or 2, 8 respectively. If a two-winding transformer is required a secondary winding may be wound over the primary winding 1 starting from the end 2. This method of construction considerably reduces the leakage inductance and together with the small distributed capacitance of toroidally wound windings substantially prevents various modes of oscillation thereby ensuring a relatively distortion-free output waveform.
