Abstract: ABSTRACT OF THE DISCLOSURE         A power transmission system having a plurality of power transmission stations for transmitting power from a power-receiv-ing line to respective branch circuits wherein each power trans-mission station includes a protection circuit providing a current path for transmitting power to or receiving power from other sta-tions.  Each protection circuit has a series circuit of a current limiting breaker and a current detector and a bypass switch in parallel with the series circuit.  When operation of one station is selectively interrupted to allow inspection, for example, of the main transformer, the bypass switch of the one station is closed to provide a current path for the associated branch cir-cults from the other stations that bypasses the associated current limiting breaker which otherwise would be required to pass full  load current of all the associated branch circuits.  By the provision of the bypass switches, current limiting breakers having lower rated current capacity may be employed without loss of circuit protection, which is provided by other breakers in the system.

Abstract: ABSTRACT OF THE INVENTION           Analog output signals from decentralised transducers for current and voltage are sampled with timing patterns generated at a decentralised location and are transmitted to a central evaluating facility in  the  form  of  digitally encoded data streams (DUR, ...).  For the purpose of generating data sets which are each based on one sampling of each analog output signal, such that the relative time displace-ment of the samplings should not exceed a predeter-mined value which corresponds to the maximum (.DELTA.) of the data-refresh intervals, latch commands (L) are generated at greater intervals in the central evaluating facility, following which in each case the digitised sampled value arriving next of each data stream (DUR, ...) is temporarily stored.  After the temporary storage has taken place, in each case a "Ready" signal (BUR, ...) is set.  The "Ready" signals (BUR, ...) are combined in a logical AND operation to form a "Data set ready" signal (DB) which is trans-ferred to a computer which interrogates the tem-porarily stored data (ZUR, ...) via a databus.

Abstract: METHOD FOR DETERMINING LIPID BOUND    SIALIC ACID IN WHOLE BLOOD            Abstract of the Disclosure The amount of lipid bound sialic acid in a whole blood sample may be determined by a method, which may be automated, involving the following steps:  adding to the sample a lower alkyl alcohol and deionized distilled water; mixing the resulting admixture; adding to it a mixture of lower alkyl chlorinated hydrocarbon and a lower alkyl alcohol; treating by mixing and centrifuging the mixture until a recoverable, substantially clear upper phase forms; recovering the upper phase and adding to it a protein-precipitating agent, pre-ferably in admixture with an adsorbing material; mixing the resulting admixture; recovering the resulting precipitate, suspending the precipitate in distilled water and deter-mining the amount of lipid bound sialic acid present.            The presently preferred mixture for addition to the upper phase is a mixture of 75% by weight phosphotungstic acid and 25% by weight silica gel on a dry weight basis.            By so determining the amount of lipid bound sialic acid present in a whole blood sample and comparing the amount with values obtained for subjects known to have cancer one may diagnose the presence of cancer in a subject.   Alter-natively, by determining the amount of lipid bound sialic acid present in whole blood samples obtained from a subject over a period of time and comparing each amount so determined With preceding amounts one may monitor the progression, remission or recurrence of cancer in a subject.

Abstract: Abstract of the Invention The invention consists of a transformer coupled low voltage power amplifiers which provides the moderate voltage (200-500 Vp-p) excitation potentials required by PZT ink jet or similar device elements.  Transformer coupling is viable in that ink jet drive requirements are "return to zero" (no net DC component).  Product safety aspects are enhanced since high voltage power supplies are not required, furthermore significant reductions in cost of implementation are realized due to the absence of high voltage power supplies and by allowing the use of monolithic power amplifiers. Savings in power may also be realized by matching the transformer to the ink jet PZT element as components of a resonant network.

Abstract: Phosphoric Acid Crystallization Process Abstract The present invention relates to the processing of phosphoric acid by crystallization.  Wet-process phosphoric acid is purified by cooling it to super-saturated conditions and adding relatively large amounts of fine, relatively pure seed crystal.  Crys-tallization thereafter proceeds under conditions which substantially favor crystal growth on the seeds which are added and disfavor secondary nucleation.  To pre-vent the crystallizing magma from reaching a viscosity which would render further processing difficult, the present invention provides for recycling raffinate in an amount sufficient to maintain the solids content of the crystallizing magma below about 40%.
