Title: Bovine nuclear transplantation.
Inventor: MASSEY JOSEPH M
IPC: A01K67/02
Filed: 1988-06-02
Abstract: A process to produce viable bovine embryos through nuclear transplantation. The process utilizes nuclear material from 4 cell and later stage developed embryos recovered from inseminated donor cows through nonsurgical or surgical means. Recipient eggs or oocytes are recovered and a portion of the ooplasm removed by micromanipulation. Individually separated cells from the nuclear material donor embryo are inserted into the recipient oocyte. The oocyte fragment and nuclear donor material are electrofused. The embryo is cultured in vitro, transferred for an interim time to a sheep oviduct and then transferred to a cow for gestation.

Abstract: An input signal determination system for determining whether the state of an ac input signal is on or off. An ac in­put signal (1) is input to a processor (21) via a photocoupler (13). The processor (21) counts the time in which the ac input signal (1) remains higher than a predetermined threshold level and the time in which it remains lower than the predeter­mined threshold level. When the counted number for the higher level is greater than a precalculated number, the ac input signal is determined to be on, and when the counted number for the lower level is greater than the precalculated number, the ac input signal (1) is determined to be off. This makes it possible to correctly determine the on/off state of ac input sig­nals within short periods of time.   
     ABSTRACT 
     An input signal discrimination method is provided wherein the on/off state of an AC input signal is discriminated. 
     An AC input signal (1) is input to a processor (21) through a photocoupler (13). The processor (21) counts pulses in a time for which the AC input signal (1) remains above a predetermined threshold level, and a time for which the signal remains below the predetermined threshold level. When the number of pulses counted while the signal remains above the predetermined threshold level is larger than a previously calculated number, it is decided that the AC input signal is on, and when the number of pulses counted while the signal remains below the predetermined threshold level is larger than a previously calculated value, it is decided that the AC input signal is off. Consequently, the on/off state of the AC input signal can be accurately discriminated in a short period of time.

Abstract: Production of polypyrrole gel applicable for casting on an impermeable substrate, such as glass, to form a conductive film thereon, by reaction of a pyrrole with an oxidant/dopant, e.g., ferric or cupric alkylbenzenesulfonate in an aprotic solvent, particularly methylene chloride or 1,2-dichloroethane. Specific examples of such alkylbenzenesulfonates include ferric ethylbenzenesulfonate and cupric dodecylbenzenesulfonate. The viscosity of the gel can be adjusted by solvent addition so that it can be readily applied to a substrate surface, such as glass. Upon subsequent solvent evaporation, a dark coherent textured film of conductive polypyrrole remains on the substrate surface.

Abstract: An apparatus and method for correctly pronouncing proper names from text using a computer provides a dictionary which performs an initial search for the name. If the name is not in the dictionary, it is sent to a filter which either positively identifies a single language group or eliminates one or more language groups as the language group of origin for that word. When the filter cannot positively identify the language group of origin for the name, a list of possible language groups is sent to a grapheme analyzer. Using grapheme analysis, the most probable language group of origin for the name is determined and sent to a language-sensitive letter-to-sound section. In this section, the name is compared with language-sensitive rules to provide accurate phonemics and stress information for the name. The phonemics (including stress information) are sent to a voice realization unit for audio output of the name.

Abstract: On recording, in each D2-MAC/packet video signal, the chrominance and luminance components are temporally decompressed in order to be recorded on a magnetic tape by two channels (A, B). The two channels serve for practically simultaneously recording the decompressed components of an odd line (2i+1) and those of the even line (2(i+1)) which follows it. Moreover, the burst of data with duobinary coding is digitised, and converted into a digital train with NRZ coding. Each digital train relating to an even-line (2(i+1)) video signal is stored in series with the digital train relating to the preceding odd-line (2i+1) video signal in order to form a packet which is temporally decompressed in order to be recorded, after duobinary recoding, with at one and the same time the chrominance and luminance components relating to the odd line (2i+1) and those relating to the even line (2(i+1)). On reading, the chrominance and luminance components of a pair of odd (2i+1) and even (2(i+1)) lines are temporally decompressed, on the one hand, and the packets corresponding to the said lines being decompressed, on the other hand. The selection in each of the packets of the first train to be placed at the front of the D2-MAC/packet video signal of the odd line (2i+1) and the selection of the second train to be placed at the front of the even-line (2(i+1)) D2-MAC/packet video signal are made as a function of error information. Means of implementing the method are also described. <IMAGE>

Abstract: Un lit fluidisé dense turbulent en un métallosilicate de zéolite catalyseur à pores moyens, qui présente une distribution spécialement adaptée des fractions de particules par poids dont l'activité se situe généralement le long d'une courbe prédéterminée de distribution de l'activité, est utilisé dans des conditons de faible sévérité, à un faible taux WHSV (kilogrammes de matières de base par kilogrammes de zéolite par heure), sous une pression modérée et dans des conditions de sévérité modérée. On obtient ainsi un taux de conversion étonnamment élevé en hydrocarbures C5+ à teneur en oléfines supérieure à 80 % environ et dont un tiers en poids environ est constitué par du distillat (C9+). Seule une quantité réduite d'oléfines cycliques et seules des quantités négligeables de composés aromatiques et de paraffines sont produites. On obtient en une seule passe entre 10 et 40 % en poids de distillat. Le lit fluidisé dense présente une densité inférieure à 640 kg/m3 (40 livres/pied3) au fond de la zone de réaction et fonctionne de préférence à une température comprise entre 250°C (482°F) environ et 371°C (700°F) environ et sous une pression supérieure à 200kPa (15 psig) environ mais inférieure à 2800 kPa (400 psig) environ. Malgré des conditions d'exploitation ''douces'', ce procédé unique permet d'obtenir une conversion d'oléfines en une seule passe et une sélectivité de production d'hydrocarbures C5+ qui dépassent toutes deux 80 %.
