Title: Supported chiral liquid membrane for the separation of enantiomers.
Inventor: PIRKLE WILLIAM H
IPC: C07B57/00
Filed: 1991-05-23
Abstract: The invention relates to a process for the high yield, cost efficient means of separating enantiomers. The process utilizes a supported liquid membrane and a chiral carrier which selectively complexes with one of the two enantiomeric optical configurations. The invention is also directed to an apparatus adaptable to the continuous and staged separation of enantiomers. In one embodiment, the apparatus utilizes a semi-permeable barrier and source and receiving locations each of which may be kept at temperatures which facilitate the complexation and dissociation processes.

Abstract: Les eaux usées à traiter sont introduites dans la partie haute d'un premier bioréacteur (10) à travers une tuyauterie d'entrée (16) et, après passage à travers des deuxième et troisième bioréacteurs (11 et 12), passent par un dispositif de sédimentation (17). Ensuite, les eaux usées traitées s'écoulent par-dessus un déversoir (18) et passent dans une canalisation de sortie (19). Les trois bioréacteurs (10, 11, 12), ainsi que le dispositif de sédimentation (17), sont logés dans un réservoir à trois cloisons transversales (21, 22, 23) décalées verticalement et une cloison transversale (24) de réservoir de sédimentation. Chaque série de cloisons décalées (21, 22, 23) est disposée de sorte que les bioréacteurs soient reliés en série, les eaux usées étant obligées de descendre à travers chaque matrice (13, 14, 15) consécutivement contre un écoulement de bulles d'air très fines provenant de panneaux d'aération (28) qui s'étendent sensiblement sous la totalité de chaque matrice. Les bactéries aérobies se nourrissent de matières nutritives présentes dans les eaux usées et se développent sur les parois rugueuses de la matrice à écoulement à contre-courant, les bulles d'air favorisant le détachement des bactéries. L'appareil comprend donc au moins trois bioréacteurs mixtes entiers séparés, fonctionnant séquentiellement, chacun servant à réduire la demande biologique en oxygène de l'ensemble des eaux usées, cette réduction étant réalisée progressivement.

Title: Refill unit for a writing instrument
Inventor: ANDREWS NEVILLE EDGAR
IPC: B43K24/08
Filed: 1992-06-03
Abstract: A refill unit (1) for a writing instrument has a writing tip (5) at one end and a ratchet mechanism (7) at the other end by means of which the unit (1) can be turned and selectively extended from and retracted into the writing instrument. The ratchet mechanism (7) is rotatable about the longitudinal axis of the unit with respect to the writing tip (5). By this means, each time the refill unit (1) is extended from or retracted into the writing instrument, the tip (5) rotates by a substantially random amount which ensures a more even distribution of wear on the writing tip (5).

Abstract: The invention relates to an inductive position sensor having an alternating-current-fed coil arrangement which contains at least two coils (13, 14), a core which is axially displaceable within these coils and the displacement of which changes the inductance of the coils (13, 14) in opposite directions, the two coils being provided in each case in one branch (12, 15) of a sensing bridge circuit, in such a manner that both coil inductances influence the bridge balance in the same direction when the core is displaced. To compensate for deviations from linearity of the sensing signal, it is proposed that one decoupling impedance (16 and 17, respectively) is in each case connected between the coils (13 and 14, respectively) and the bridge voltage tap (18) of the sensing bridge circuit, and that in each case a line (19 and 20, respectively) branches off between the associated decoupling impedance and one coil, which line is connected to in each case one of the two bridge supply lines, this line (19, 20) containing an adjustable impedance (21, 22). <IMAGE>

Abstract: A method for improving the compilation of computer code (200) is described. In the described invention, a storage array (245) is created (310) into which a set of code statements are temporarily placed (320) before compilation. Such set of code statements may include statements which require other parts of the code to be compiled before they can be compiled or may be parts of the code which are not directly related to the running of the computer program, e.g. trace point descriptors. The code statements are later retrieved (230) from the storage array (245), compiled in a language compiler (210) (340) and inserted into the correct position within the compiled computer code (220).

Abstract: First absolute position detecting section (12-20) generates an A.C. output signal having a phase electrically shifted in accordance with a position of a moving object, and samples a counted value of a counter circuit in response to an electrical phase change at a zero cross time point of the A.C. output signal, so as to output the sampled counted value of the counter circuit as absolute position data of the moving object. Second absolute position detecting section (21-2D, 30, 40, 50) generates one or more delayed clock signals that are delayed from a clock signal on the basis of which the counter circuit counts up by an amount of time smaller than one period of the clock signal, and utilizes the one or more delayed clock signals to measure the zero cross time point of the A.C. output signal in accordance with a unit time smaller than the one period of the clock signal, so as to output, as the absolute position data, the measured time point after having been added to the sampled counted value.
