Patent CA-2163485-A1 (CA)
Inventor: BLOCH NICOLAS
IPC: B01F35/60
Filed: 1995-11-22
Abstract: Un récipient étanche contient de l'additif sous forme liquide. Un tube plongeur permet d'envoyer l'additif à une enceinte de chauffage où le liquide se vaporise avant d'être envoyé à un collecteur-mélangeur à travers un étranglement. Le débit d'additif est contrôlé par l'intermédiaire de la pression régnant au-dessus du liquide dans le récipient grâce à une vanne pilotée reliée par un régulateur de pression à un calculateur. Celui-ci reçoit les valeurs de consigne de concentration du mélange par une entrée. Il est avantageusement relié à un capteur de la température de l'enceinte et/ou à un analyseur de la composition du mélange. Application notamment aux appareils d'anesthésie.

Title: Selectively cleavable linkers based on iminodiacetic acid ester bonds
Inventor: LEBL MICHAL
IPC: C07K5/00
Filed: 1994-06-21
Abstract: The present invention is directed to linkers based on ester bond linkages, especially iminodiacetic acid ester bond linkages, for use in solid phase peptide synthesis. In particular, the invention is directed to cleavable linkers that can release peptide from the solid phase support under relatively mild conditions by formation of a diketopiperazine or other cyclic structure, such that the cyclic structure remains on the solid phase support, and, in a second cleavage, under mole stringent conditions of high pH. The invention is further directed to solid phase supports prepared with multiple cleavable linkers, including a linker that is cleaved by formation of a cyclic product. One such second linker is an ester of hydroxymethylbenzoic acid, or esters formed by carboxy groups of aspartic or glutamic acid.

IPC: G08B29/18
Filed: 1996-04-01
Abstract: A method and apparatus for producing a temperature stabilized frequency from a signal generator in a monitoring station is described. The signal generator monitors the voltage response of an RC circuit where the resistive portion is formed by a thermistor, to produce a time-dependent signal. A comparator compares the time-dependent signal to a reference voltage to determine a rise time of the voltage across the capacitor. Based upon a software timer loop, the signal generator determines a temperature range by selecting data from a look-up table based upon the rise time of the RC circuit.

IPC: G06F13/00
Filed: 1995-02-28
Abstract: A data storage device includes a CMIP application component (42) which receives data on network objects using the CMIP protocol from the network manager of a main network. For each attribute of each object, a CMIP/SNMP mapper component (44) converts the CMIP object class name, attribute name and distinguished name of the object into the corresponding SNMP object identifier and the CMIP attribute value into the corresponding SNMP attribute value and this data is stored in MIB (46). An SNMP application component (48) receives requests for information from a network manager of a local network. In order to service a valid request, the SNMP application component (48) retrieves the required data from MIB (46) and supplies this data to the network manager for the local network using the SNMP protocol. For changes in the values of certain attributes of certain objects, the SNMP application component issues traps to the manager of the local network.

Abstract: The memory of the credit/debit card contains: - a first identification file, called 'member file' which identifies the card owner; - a second posting file, called a 'points file'; - and a third file containing credit data about card owner for a number of shops/stores etc. at which the card owner makes transactions. The file contains, for each shop/store, a place identification code and several user purchase fields. The method actuates a given algorithm, as a function of the particular shop/store, at the moment a transaction is made, using the data contained in one or more of the fields relating to the shop/store and/or another shop/store. The data is then written into the 'points file' and in the third file, a receipt may be or may not be printed as a result of the actuation of the processing algorithm. For each commercial enterprise the third file fields include a register called 'activity code', identifying an activity sector. A specific processing algorithm is realized in the 'point file' at the time of a purchase at a particular enterprises as a function of the third file fields user by the card owner at one or more enterprises having the same 'activity code'. An Independent claim is included for a points/discount calculator.
