Patent GB-1548741-A (GB)
Title: Heterogenous specific binding assay method and test systemfor use therein
IPC: G01N33/536
Filed: 1976-04-23
Abstract: A test process operating using a specific bond for the investigation of a liquid medium on a ligand is described. The test process comprises the following steps:   (a) the liquid medium is brought into contact with a reagent which contains a conjugate of a labelling substance which has a predetermined characteristic and a specific binding substance, the reagent and the ligand forming a binding reaction system which   (i) forms a bound phase of the labelling conjugate, in which the specific binding fraction is bound thereto by a specific binding component, and (ii) forms a free phase of the labelling conjugate, in which the specific binding fraction is not bound thereto by a specific binding component,     (b) determination of the said characteristics either in the bound phase or in the free phase as a measure of the said ligands in the said liquid medium. The said characteristic of the labelling substance proves to be active in the following reaction systems:     (1) as a substrate in an enzyme-catalysed reaction,   (2) as a reactant in a cyclic reaction system,   (3) as a reactant in a chemiluminescent reaction system, or (4) as a coenzyme in an enzyme-catalysed reaction.

Title: Improvements in and relating to laminated endless driving or conveyor belts

Filed: 1960-05-16
Abstract: 907,157. Laminates. SIEGLING, H. May 16, 1960, No. 17148/60. Class 140. A conveyer belt consists of at least two tensile layers 3 and 4 of a polyamide or polyurethane, and an intermediate layer of synthetic thermoplastic material of lower elongation in the direction transversely of said belt than the said tensile layers, and of greater resistance to solvents and heat than these layers. The intermediate layer has threads 5 of polyester material running in a direction transverse of the belt, the threads being embedded or enveloped in a layer 6 of polyamide or polyurethane capable of being interwelded with the tensile layers. Polyamide multifilament threads may be used, the mixed yarn consisting preponderantly of polyamide and a small proportion of polyester yarn. A fabric may be built in, in which the polyester forms the weft threads, and polyamide forms the warp threads, thus on interwelding the polyamide threads fuse with the polyamide tensile layer. The layers may be assembled by application of pressure after treating the fabric with a solvent, e.g. phosphoric acid, formic acid, phenol, cresol, or glycol, or by heating the fabric, e.g. using high-frequency heating to dissolve the surfaces of the polyamide yarn and layers. Specification 610,170 is referred to.

Patent GB-219327-A (GB)
Title: A process for separating hafnium and zirconium
IPC: C01G25/04
Filed: 1924-07-17
Abstract: Hafnium and zirconium are separated by fractional crystallization, precipitation or sublimation of their halogen compounds other than double fluorides.  A zirconium material containing hafnium may be treated with sulphuric acid, the hydroxides precipitated with ammonia and dissolved in hydrochloric acid and the solution evaporated and cooled whereby the oxychloride mixture separating out will be enriched in hafnium, and may be further treated by dissolving in hydrochloric acid and repeating the operation.  Other hydrohalogenic acids may be used instead of hydrochloric acid.  The oxychlorides may be precipitated from the aqueous or weakly acid solution by adding the corresponding strong hydrohalogenic acid or a soluble halogenide such as calcium halogenide or by adding alcohol or other suitable precipitant.  Or a similar precipitation may be effected by adding water to a solution containing hafnium and zirconium in concentrated hydrohalogenic acid since the solubility is at a maximum at a certain concentration of acid. Alternatively, the mixed tetrahalogenides may be submitted to fractional sublimation, the non-volatilized portion being enriched in hafnium.  The halogenides may be dissolved in water or in the corresponding hydrohalogenic acid, alcohol, or the like after which the process described above may be applied.
