Title: Method for preparing of r- (+)- 1- methyl- 2- (hydroxyethyl)- pyrolidene
Inventor: NIKIFOROV TEO T
IPC: C07D207/08
Filed: 1984-11-23
Abstract: The method is intended for application in the pharmaceutical industry and the compound obtained thereby is used in the manufacturing of 2-(2-(p-chloro-)-α-methyl-α-phenyl/benzyl/oxi/ethyl-1-methylpyrolidene hydrogenfumarate, the active ingredient of an antihistamine agent. The R-(+)-1-methyl-2-(2-hydroxyethyl)-pyrolidene is prepared by a simplified method, without separation of the intermediate products, at high yield and is of high optical purity. N-methyl-2-pyrolidinethione is alkylated with benzylbromoacetate, the resulting salt is treated with triphenylphosphine and triethylamine, the 2-(benzyloxicarbonyl methylidene)-1-methylpyrolidine thus obtained is reduced by sodium cyanoborohydride to an N-methyl-2-(2-pyrolidinyl) acetic acid benzyl ester racemate. The ester is subjected to racemic resolution using (+)-di-p-toluyl-tartaric acid to give the optically active benzyl ester of the N-methyl-2-(2-pyrolidinyl) acetic acid, which is then reduced with lithium aluminium hydride.

Title: Ensembles a faible consommation d'energie destines a appliquer un gradient de temperature a un reseau a indice de refraction
Inventor: LACHANCE RICHARD L
IPC: G02F1/01
Filed: 2003-02-06
Abstract: L'invention concerne des ensembles pratiques et à faible consommation d'énergie (1) destinés à appliquer un gradient de température à un réseau de Bragg sur fibre (5). Une application de ces ensembles consiste, par exemple, en un réglage actif de la dispersion chromatique du réseau. Le gradient de température est produit dans un élément conducteur de chaleur (7), avec lequel le réseau de Bragg sur fibre (5) est en contact thermique continu, à travers des éléments (9, 11) commandant la température des extrémités de l'élément conducteur de chaleur (7), appliquant ainsi le gradient de température au réseau de Bragg sur fibre. Un premier mode de réalisation préféré comprend un élément de recirculation de la chaleur (17) permettant la recirculation de la chaleur entre les deux extrémités (29, 31) de l'élément conducteur de chaleur de forme allongée, fournissant ainsi un réglage rapide et dynamique du gradient de température avec une perte de chaleur minimale. Un second mode de réalisation fournit une isolation de l'environnement extérieur afin de découpler le gradient de température souhaité des fluctuations de température ambiante, améliorant ainsi la commande de la réaction optique d'un réseau de fibres.

Filed: 1989-11-29
Abstract: A mobile TV receiver is provided in which the viewing screen can move left and right or up and down and be tipped or tilted by remote control as the viewer chooses. The TV receiver is divided into a head portion including a CRT-tube and a lower body portion accommodating driving elements and supporting the head portion. The head portion is adjustably connected to the upper part of the supporting body portion so that only the head can lean over, tilt up and down, and move upward and downward by operation of the driving elements under the viewer's control. The viewer can thus remote-control the TV set back and forth, and adjust it exactly as desired to make the TV screen comfortably visible.

Abstract: 10GLB0289/? 7802A                            89P7802 ABSTRACT OF THE DISCLOSURE      A method of making a molded plastic component of an internal combustion engine. The method disclosed is for making a fuel rail and comprises constructing particular core pins of the mold with threaded connections that form seals between them when they are disposed in proper position within the mold cavity for the molding of a fuel rail.  The core pins serve to form a main fuel passage and auxiliary fuel passages which transversely intersect the main fuel passage.  Each core pin that forms an auxiliary fuel passage comprises a screw thread on its inner end that threads into a corresponding complementary threaded recess in the side of the core pin that forms the main fuel passage to create a corresponding seal.  This sealing prevents any significant flash from forming in the fuel rail at the intersection of each auxiliary fuel passage with the main fuel passage.  After the plastic has been molded, the core pins are unthreaded and withdrawn.

Title: Trench gate complimentary metal oxide semiconductor transistor
Inventor: SOLOMON ALLEN L
IPC: H01L27/092
Filed: 1990-02-01
Abstract: A complimentary trench gate metal-oxide semiconductor transistor is disclosed along with  a resulting product. The process for forming the transistor comprises forming a trench within  the  semiconductor substrate,  wherein  the semiconductor substrate is doped to a first relative type. A layer doped to a second  relative type is applied  about the surface of the  trench.  An  insulating layer is  then formed within the trench upon said first layer.  A  region of gate material  is formed  within the  trench upon  said insulating layer.  Source and drain regions are formed  by doping first and second regions adjacent the trench to the opposite relative polarity of the substrate.  Segments  of the first and second  regions are then  doped to the  same relative polarity  as the  substrate, the  segments  being isolated from the substrate by  remaining portions of  the first and second doped regions.  The first layer therefore extends between said source and  drain about said  trench, and wherein the  gate region  is isolated  from the  first layer by the insulating layer.
Patent CA-2011562-A1 (CA)
IPC: H04Q3/00
Filed: 1990-03-06
Abstract: This invention relates to the application of an audible logo to a telecommunications call, for identifying the common carrier serving that call. A call is received in an operator assistance system. After applying a calling card prompt tone and prior to connecting the call to an operator position or receiving further digits such as those for a calling card number, the operator assistance system connects an audible logo, identifying a common carrier, to the call. Advantageously, a telephone customer receives the information necessary to identify whether his/her preferred common carrier is going to be used on this call at a sufficiently early time to make it convenient to disconnect and reoriginate. This information is particularly important for calls originated away from home or office, calls that are likely to be operator assistance (0 or 0+ directory number) calls. Subsequently, the operatorassistance call is processed as in the prior art. Advantageously, this arrangement identifies the common carrier on the calls where this identification is most needed without adding holding time to all direct dialed station toll calls.

Abstract: Abstract of the Disclosure The ratchet mechanism in a reversible ratchet wrench is sealed by novel means.  The sealed reversible ratchet wrench includes a ratchet body having a head portion and a handle portion.  The head portion has a head cavity formed therein, which cavity receives the ratchet mechanism.  The ratchet mechanism communicates exteriorly of the head cavity via at least two journal bearings which respectively receive journal pins associated with the ratchet mechanism.  The novel sealing means comprises a pair of annular lip seals, each of which includes an opening that receives one of the journal pins.  The annular lip seals bridge the gap between the exteriorly communicating journal bearings and journal pins, thereby facilitating the retention of lubricant and hindering the entry of foreign particles in the head cavity and ratchet mechanism housed therein.
