Patent CA-2054463-A1 (CA)
Title: Tamper evident container
Inventor: GAUDREAULT MARIO
IPC: B65D55/06
Filed: 1991-10-30
Abstract: A container adapted to securely engage a cover displaying a peripheral depending skirt comprises a body with side walls having an upper edge portion adapted to engage the skirt of the closure. The side walls include a peripheral inverted L-shaped flange. Integrally formed with the flange on two sides of the container is a downward projection including a frangible tab which must be broken to remove the cover from the container; however, the broken tabs do not hinder the reclosure of the container, nor the handling of the container. The side projections are so shaped as to allow similarly constructed containers to be nested one into the other.

Title: Pager receiver with message display function
Inventor: IDE MOTOKI
IPC: H04W88/02
Filed: 1992-02-07
Abstract: A pager receiver of the present invention using a microprocessor for control receives messages corresponding to a plurality of ID numbers set to it and stores the received messages in the message memory area for each call distinction code indicating the destination ID number of the received message.  The message memory area is provided with a storage area of fixed length for each call distinction code, for example, and each area stores one message.  In this case, received messages are sorted by call distinction codes before being stored.  Messages are read out of the message memory areas in ascending or descending order of call distinction codes and displayed on the LCD.          Alternatively, the message memory area may be variable in length.  Such a memory area comprises a directory to store the call distinction code and sectors to store messages and the messages are sorted before being stored using the call distinction code as a key.
Patent CA-2060931-A1 (CA)
Inventor: PARE J R JOCELYN
IPC: G01N30/12
Filed: 1992-02-10
Abstract: The generation of volatiles from liquid or solid materials is enhanced and accelerated by exposure to microwave radiation.  Normally the energy transfer is effected preferentially toward the liquid or solid materials over the generated gaseous volatiles.  Sufficient energy is provided at a selected rate that enhances the generation of volatiles to produce headspace samples.  Alternatively, the rate can be selected so as to disrupt the equilibrium normally present between the liquid or solid phase and the gaseous phase and produce purge and trap samples; the latter process resulting from the selective energy transfer toward the liquid or solid phase over the gaseous phase.  The rate of energy transfer can be chosen so as to bring the medium being subjected to microwave radiation to its supercritical state.  The material having reached that state can further be used in numerous applications such as supercritical fluid extraction.

Inventor: BENSON SIDNEY W
IPC: B01J23/10
Filed: 1990-10-26
Abstract: Procédé pour la production à fort rendement de Cl2 à partir de HCl gazeux, au moyen d'un catalyseur (1) comprenant un oxyde métallique de transition, un chlorure métallique alcalin et, accessioirement, un chlorure de terre rare trivalent, qui agit de manière productive à des températures modérées et sans que le catalyseur (10) s'évapore. Le procédé comprend deux phases:1) une phase de chloruration dans laquelle le HCl est mis en contact avec le catalyseur (1) à une température élevée, transformant l'oxyde métallique de transition en un chlorure métallique de transition avec élimination d'eau; et (2) une phase d'oxydation dans laquelle le chlorure métallique de transition produit dans la première phase est mis en contact avec une source d'oxygène à une température d'un moins environ 300 °C mais cependant inférieure à 400 °C et suffisamment élevée pour que le Cl2 se dégage et que le chlorurre métallique de transition se retransforme en oxyde métallique de transition. La température de la phase d'oxydation est supérieure à celle de la phase de chloruration. Préférablement, l'oxyde métallique de transition est du MnO2, dans ce cas le MnO2 se transforme en MnCl2 lors de la première phase avec l'émission du Cl2. L'oxyde métallique de transition peut également être du Co2O3, Co3O4, Cr2O3, MiO, Mi2O3, Mo2O3 ou du CuO.
