Patent CA-2074447-A1 (CA)
Inventor: BREIDENSTEIN CHARLES J
IPC: H04Q11/04
Filed: 1992-07-23
Abstract: A time division multiplex switching system converts call formats and signalling protocols so that calls can be interchanged between circuits originating in different networks thereby providing a gateway for telephone transmissions originating from sources (e.g., foreign countries) having differences in transmission (signal attenuation characteristics and companding laws) and signalling and numbering plans or protocols. This switching system is characterized by a processor which is programmed to identify the circuits requiring interconnection and to process signalling messages in accordance with the signalling systems and formats used in the circuits, while translating the signalling messages into common, protocol independent signaling messages which are used for establishing time division multiplex connections in a time slot interchange which is connected to the circuits via PCM highways and for exchanging signalling information (e.g., as to seizure, detection and release) between the circuits; the signalling messages also containing information for conversion of PCM data messages which are switched in the time slot interchange thereby reconciling differences in transmission, such as the companding law used for PCM encoding and decoding and the attenuation (pad value) of the call data in the circuits. The circuits may, for example, be incoming and outgoing trunks.

Abstract: Dispositif à ensemble de bouchon et de tube comprenant un tube (11) destiné à contenir un produit, un ajutage dont une extrémité est montée à un bout du tube et comportant une section de paroi mince (23) que l'on peut perforer afin de ménager une sortie à l'autre extrémité, ainsi qu'un bouchon (17). L'ajutage a une section transversale axiale plus petite que celle du tube. La jonction entre le tube et l'ajutage définit une surface inclinée de transition (15) destinée à permettre l'écoulement sans cavitation du tube à l'ajutage. Le bouchon a une section transversale intérieure dimensionnée pour venir au contact de l'ajutage, et une section transversale extérieure inférieure à la section transversale du tube. Le bouchon comporte une pointe de perforation centrée axialement (33) positionnée dans une première position espacée de la paroi mince et mobile jusqu'à une seconde position afin de perforer ladite paroi mince. Le moyen de perforation comprend un bord en forme de ciseau (37) permettant de former un trou dans la paroi mince sans fragmenter la paroi. On a également prévu des nervures (27a, b, c) positionnées dans le tube afin d'empêcher l'entrée du bouchon dans l'ajutage, lorsqu'une pluralité de ces ensembles sont empilés les uns sur les autres.

Abstract: A water conserving toilet having a set of holes around the rim to provide a washing of the bowl includes enlarged holes towards the front of the rim to create a focused jet of water used to initiate siphon action.  The enlarged holes are positioned on an elevated multi-plateau boss within the rim.  The boss extends beyond the highest normal level of water in the rim. and has a vent to vent air from the rim.  A sloped entry within the receiving chamber connects the tank of the toilet to the rim to further increase the momentum of this water.  The jet from the enlarged front holes in the rim is further focused by a groove extending on the bowl's lower wall.

Title: Preparation of low molecular weight cellulose esters
Inventor: BUCHANAN CHARLES M
IPC: C08B3/02
Filed: 1991-04-12
Abstract: A process is disclosed for the preparation of low molecular weight, high hydroxyl cellulose esters ideally suited for use in coating applications. The new synthetic procedure involves treating a cellulose polymer with trifluoroacetic acid, a mineral acid, an acyl or aryl anhydride in an appropriate carboxylic solvent followed by, optionally, in situ hydrolysis. Typical reaction times for conversion to a triester are 5 to 30 minutes while typical hydrolysis times for far hydrolyzed mixed esters range from 4 to 7 hours. Molecular weight loss occurs during formation of the cellulose triester permitting concentrated reaction mixtures and easier isolation of the product ester.

Filed: 1992-10-23
Abstract: ABSTRACT     In a modular system for constructing devices, there is a base part 1 that extends in the X-Y plane and at least clamping part 2 that can be attached to said base part in various selectable positions.  The base part 1 comprises elevations 6 that are so arranged to be regularly spaced in a grid pattern in the X-Y planes, each having reference surfaces 6a; 6b that are oriented in the Z-direction.  Optionally, connecting elements extend between the elevations 6 and the clamping part 2.  The distance between reference surfaces of adjacent elevations and the spacing of the reference surfaces on an elevation is either equal or the distance between reference surfaces of adjacent elevations is an even-numbered multiple of the spacing of the reference surfaces on the same elevation.  This results in a high degree of flexibility of the modular system, at the same time providing possibilities for simple and reliable clamping.
