Patent CA-2215364-C (CA)
Inventor: SCHERER HENRY W
IPC: H01H85/02
Filed: 1997-09-12
Granted: 2005-03-29
Abstract: A circuit-interrupting device for electrical power distribution and transmission systems is provided having improved handling provisions for removal and installation with respect to conventional mountings. The handling provisions permit the circuit-interrupting device to pivot about the lower hinge of the mounting before the circuit-interrupting device is lifted out of the mounting via a handling tool. This permits the dimensions of the circuit-interrupting device to be greater than conventional circuit-interrupting devices. For example, in a preferred embodiment, the circuit-interrupting device includes exhaust diverter structure which directs exhaust away from the mounting, the exhaust diverter structure extending beyond the maximum dimensions which allow the circuit-interrupting device to be directly lifted out of the mounting hinge, i.e. the exhaust diverter structure interferes with the mounting if the circuit-interrupting device is lifted in a direction out of the mounting. The handling provisions include a handling loop on the circuit-interrupting device that is spaced away from the trunnion of the circuit-interrupting device which is received by the lower hinge of the mounting. The location of the handling loop is selected so as to provide suitable pivoting of the circuit-interrupting device before lifting out of the mounting hinge.

Abstract: A method is provided for determining origin ZIP code for a postage meter. The method includes receiving at a data center a call that originates from the location of the postage meter. Using caller ID, the data center determines the phone number originating the call. The data center also determines the identification of the postage meter. If the phone number has changed from a phone number from the previous phone call for the postage meter, the data center obtains a five-digit ZIP code for the address corresponding to the phone number. If the five-digit ZIP code has changed from a previous ZIP code used for postal accounting during previous transactions for the postage meter, the data center obtains a new certificate based on the five-digit ZIP code and downloads the new certificate to the postage meter. The data center transfers postage meter register values to a new postal account for the new certificate.

Title: Dry-formed absorbent web material
Inventor: SCHILKOWSKI HELMUT ERWIN
IPC: D04H1/542
Filed: 1997-02-12
Granted: 2010-04-06
Abstract: An inexpensive sheet or web shaped fibre material for use e.g. in sanitary napkins typically consists of a mixture of short cellulose fibres and some 15 % of relatively long, thermoplastic binder fibres. It is a noticeable problem that the short fibres "dust" out of the material, and according to the invention this is remedied in that the material, when made by dry forming, is provided with a surface coating of very thin layers of pure binder fibres. In addition to a marked holding back of the dust, these layers condition that the amount of binder fibres in the base material can be halved and that the breaking stress of the material is noticeably improved. Thereby the products are usable not only as inserts, but also as individual, self-contained units e.g. for wiping in domestic or industrial cleaning.

Abstract: A full bridge DC-DC converter has four switching devices in two switching legs each of two devices connected in series betwen two supply voltage terminals, junction points of the legs being connected to a primary winding of a transformer, from a secondary winding of which an output voltage of the converter is derived by rectifying and filtering. The output voltage is regulated by phase shift control of the switching devices. Zero voltage switching (ZVS) of the switching devices under potentially all converter load conditions is provided by snubber capacitors, connected in parallel with the switching devices, in conjunction with two inductors each connected between the junction point of a respective one of the switching legs and a point at a voltage midway between the voltages of the supply voltage terminals, which can be provided by a capacitive voltage divider between the supply voltage terminals. The inductors typically have different inductances, and one of the inductors may be omitted.

Title: Process for sequentially applying sagd to adjacent sections of a petroleum reservoir
Inventor: LUHNING RICK W
IPC: E21B43/24
Filed: 1998-10-26
Granted: 2003-05-27
Abstract: Steam assisted gravity drainage ("SAGD") is practised in a first section of a reservoir containing heavy oil. When production becomes uneconomic, steam injection into the first section is terminated. Non-condensible gas is then injected into the section to pressurize it and production of residual oil and steam condensate is continued. Concurrently with pressurization, SAGD is practised in an adjacent reservoir section. As a result, some of the residual oil in the first section is recovered and steam loss from the second section to the first section is minimized.

Un identificateur est construit pour le type abstrait de données qui est sensiblement unique au type abstrait de données, dans lequel l'identificateur comprend une concaténation de différents attributs pour le type de données abstrait. L'identifiant construit est haché pour générer une valeur de hachage de signature pour le type abstrait de données, qui est ensuite stockée à la fois dans la base de données et une définition de la classe pour le type abstrait de données. Lorsque la définition de la classe est instanciée en tant que fonction de bibliothèque, elle accède au type abstrait de données de la base de données, et compare la valeur de hachage de signature de la base de données et la valeur de hachage de signature de la définition de la classe afin de vérifier que la définition de la classe n'est pas périmée. La définition de la classe est périmée lorsque le type abstrait de données a été modifié sans que la valeur de hachage de signature ait été générée à nouveau et stocké à nouveau dans la base de données et dans la définition de la classe.
