Abstract: Process for the manufacture of composite plasma membranes with the production of a pore-free impermeable polymer layer on a porous substrate through the plasma polymerization of a gaseous mixture, said gaseous mixture containing a hydrocarbon as the matrix-forming component and a nitrogen-, silicon-, sulphur- or phosphorus-containing inorganic compound as the non-matrix-forming component and an oxygen-containing compound, by means of glow discharge in an electrical alternating field. The pore-free impermeable polymer layer is produced directly on a porous substrate without the use of an impermeable intermediate layer, said porous substrate having a pore diameter of less than 100 nm on the side facing the pore-free polymer layer. The composite plasma membranes are used for separating C.sub.1 -C.sub.3 alkanols from mixtures thereof with other organic liquids using the method of pervaporation.

Abstract: A method of purifying full length synthetic target oligonucleotides from a mixture of oligonucleotides, particularly from a mixture containing truncated or failed sequences. The method involves attaching a short nucleotide sequence complementary to the 5' end of a target oligonucleotide to a solid support. The complementary between the most 5' nucleotides of the target oligonucleotide and the bound oligonucleotide results in hybridization which serves to retain the target oligonucleotide. Truncated or failed sequences lacking 5' sequences complementary to the attached oligonucleotide, fail to hybridize and therefore are not retained. The method makes it possible to purify gram quantities of synthetic deoxyribonucleic acids or ribonucleic acids and sequences which have modifications, such as on the phosphate backbone. The support-bound nucleotide sequences are stable under conditions of purification and therefore can be reused.

Abstract: A spiral overlay having multiple variations, but generically, comprised of wire spirals intermeshed together by connecting rods extending across the conveyor in the transverse direction. Broadly, a first overlay is made up of spirals which may be tapered and afford pitch control by incorporating elongated loops in the spirals to limit the movement of the rods therein. The elongated loops also provide for collapsibility of the spirals relative to one another. A second overlay is made of integral or modular spirals such that the overlay includes upstanding spiral elements on its conveying surface to provide traction and separation of the articles being conveyed.

Abstract: After data is written into a desired memory cell of a memory cell array, a booster circuit verifies the threshold voltage of the memory cell in which data is written. An erase timing signal generation circuit connected to a control circuit generates a timing signal for a short period of time when a memory cell having a threshold voltage higher than the power supply voltage. An erasing voltage generation circuit applies a negative erasing voltage to the memory cell in which data is written for a short period of time according to the timing signal supplied from the erase timing signal generation circuit to slightly lower the threshold voltage of the memory cell so as to prevent the excessive writing.

Abstract: A box or container assembly formed of plastics material and particularly adapted for use in a beverage syrup supply system is covered by opposed lid members whose exposed surface contains an organization of channel-defining projections for stacking superposed containers optionally in columnar- or cross-stacked array. A hinge arrangement effects release from the container of any lid subjected to an excessive lateral force and enables the lids, when open, to be held against the container body with minimal lateral flair for compact nesting. Various forms of access openings are described for accessing a syrup bag spigot and for attaching same when the container assembly forms part of a beverage syrup supply system.

Abstract: The present invention is directed to an apparatus for electrolyzing water. The electrolyzing apparatus includes a rectangular parallelpiped shaped casing having first and second chambers through which water flows. An inlet port at the first chamber conducts water into the first chamber from outside of the apparatus. Separate first and second outlet ports at the second chamber conduct the water to outside the apparatus from the second chamber. The first and second chambers are partioned by a wall. A communication path through the wall provides communication from the first chamber to the second chamber. Anode and cathode plates are disposed within the second chamber to generate a potential difference therebetween, so that the water which flows through the second chamber is electrolyzed. The communication path includes a fluid friction generating device, such as a plurality of circular holes having various diameters which are aligned along a line perpendicular the direction of the water flow.

Abstract: An electrical connector assembly is provided which assumes a fully coupled state even if it was in a semi-coupled state prior to being attached to a support bracket (B). A lever has an inclined coupling surface which draws a semi-coupled female connector housing in the coupling direction, thereby ensuring a fully coupled state. A support bracket (B) cannot be fully inserted until the lever has moved the connectors from a semi-coupled to a fully coupled condition. If the connectors are improperly connected a second inclined surface of the lever decouples the connectors as the support bracket (B) is engaged.

Abstract: A non-volatile semiconductor memory device includes a flip-flop circuit for holding write data in one of first and second states. A bit line is connected to the flip-flop circuit via a switching element, and a transistor charges the bit line. A non-volatile memory cell, connected to the bit line and having a MOS transistor structure, stores data when a threshold thereof is set in one of first and second threshold ranges, wherein at the time of a write mode the threshold of the memory cell is shifted from the first threshold range towards the second threshold range while the flip-flop circuit remains in the first state and the shift of the threshold is not effected while the flip-flop circuit remains in the second state, and at the time of a verify mode following the write mode the bit line is kept at a charge potential by the charging transistor while the threshold remains in the second threshold range.

Abstract: New methods of loading solid supports for oligonucleotide synthesis are presented. The new methods comprise coupling a succinylated nucleoside to a solid support using diisopropylcarbodiimide (DIC) as an activator and N-hydroxybenzotriazole (HOBT) as an acid catalyst. DIC is substantially cheaper than the currently used activating agent, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (DEC). Furthermore, in the preferred embodiment, when it is used in combination with HOBT, coupling is more efficient, requiring less nucleoside to achieve the same loading densities as in the prior art. The loading process is faster than prior art methods and the overall cost savings of about 43% are realized.
