Patent EP-0065863-A2 (EP)
Inventor: YOLDAS BULENT ERTURK
IPC: C01F7/36
Filed: 1982-05-17
Abstract: Method of producing ceramic-forming oxide powders with variable and predetermined sintering characteristics such as MgO, BaO, Ta 2 O 5 , ZnO. CeO, SnO, CaO, Cr 2 0 3 , CoO, As 2 O 3 , Sb 2 0 3 , ZrO 2 , TiO 2 , ThO 2 , Y 2 O 3 , Si0 2 , UO 2 , Al 2 O 3 , and Ti02. There is a relationship between sintering rate of oxide powders produced from metal alkoxides and degree and nature of hydrolysis. This relationship between the degree of hydrolysis of the corresponding alkoxide and the density of the resulting oxide is determined by hydrolyzing several samples of the alkoxide using different amounts of water in diluted systems. The samples are sintered to produce the metal oxide and its density is measured. A desired density can then be achieved by using the amount of water of hydrolysis which corresponds to that density. Oxide powders with very high rate of sintering characteristics can be achieved by using at least 5 moles of water of hydrolysis per mole of alkoxide.

Abstract: A clocking mechanism is provided for multiple overlapped dynamic programmable logic arrays which are used in a digital control unit wherein a sequence of control words are used to produce successive groups of control point signals. Such a control unit includes a plurality of dynamic programmable logic arrays (24-29) for individually producing different ones of the control words. Each such control word includes a strobe field which is coded to identify a programmable logic array other than the one which produced it. The control unit also includes control circuitry (30, 31, 35, 37, 43, 45) responsive to the control words for producing the control point signals for successive machine control cycles. The control circuitry includes circuitry (37, 45) responsive to the strobe field in each control word for producing a strobe signal (Sl, S2, SA, SB, SC or SD) for selecting the next programmable logic array (24-29) to supply a control word to the control circuitry. This control unit further includes clocking circuitry (60) responsive to the strobe signals (S1, S2, SA, etc.) produced by the control circuitry for producing clocking signals (PC1-PC9) for the dynamic programmable logic arrays (24-29). Such clocking circuitry includes only combinatorial logic circuitry for producing the clocking signals.

Abstract: Bekannte Zeitmeßverfahren verwenden zur Berechnung eines Meßwertes die Differenz von Zeitabständen, die zwei zwischen ihrer Erzeugung und der Zeitmessung unterschiedliche Verzögerungen erleidende, wiederholbare Einzelsignale von einer jeweils zugehörigen Zeitbasissignalflanke aufweisen. Diese Zeitabstände werden mit derselben Zeit/Amplituden-Wandlerschaltung gemessen, deren Kennlinie einen geeichten, wenigstens einer Periodenlänge des Zeitbasissignals entsprechenden, durch lineare Interpolation zwischen zwei Eichmeßpunkten gebildeten Bereich umfaßt. Zur Vermeidung von Meßfehlern, die aufgrund von Nichtlinearitäten der tatsächlichen Kennlinie im geeichten Bereich entstehen können, wird erfindungsgemäß jedes der beiden Einzelsignale n-mal phasenstarr zum Zeitbasissignal erzeugt und der Zeit/Amplituden-Wandlerschaltung jeweils einmal unmittelbar und n-1-mal mit jeweils einer anderen zusätzlichen Verzögerung zugeführt, wobei die Verzögerungswerte so gewählt werden, daß sie in etwa jeweils ein ganzzahliges Vielfaches einer Einheitsverzögerung τ0 sind und n . τ0 gleich der Periodenlänge der Zeitbasissignals ist. Zur Meßwertbildung wird dann die gemittelte Differenz der für die beiden Signalgruppen gewonnenen Ausgangssignalwerte der Zeit/Amplituden-Wandlerschaltung verwendet.

Abstract: A method for reducing the cross-reactivity of LH when analyzing for hCG in a biologically derived fluid sample which includes both hCG and LH. The technique may be a conventional sandwich-type immunoassay in which the hCG is bound to immobilized antibody and to free labeled antibody, to form a sandwich. The binding to the two different antibodies may be performed either simultaneously or sequentially. The improvement involves the binding of the labeled antibody in a buffered solution at a limited concentration of salt, typically sodium chloride, namely, to a maximum concentration of 0.5 weight/volume % of the salt, to reduce the cross-reactivity with LH. Reduction in LH cross-reactivity is aiso assisted by reducing the buffering agent concentration.
