IPC: H04M15/00
Filed: 1995-08-25
Abstract: Une carte (100) à puce est munie d'une horloge interne donnant l'heure et d'un calendrier (106). Entre la carte (100) et le poste d'abonné (209, 300) dans lequel elle est insérée, ont lieu une communication de l'identité de l'abonné et un accord négocié sur la durée pendant laquelle le poste d'abonné doit maintenir l'identité transférée. Pendant ce temps, le poste de l'abonné (209, 300) est activé par l'identité de l'abonné et la carte reste pratiquement "muette" et donc inutilisable jusqu'à ce que la durée soit écoulée.
Patent CA-2177307-A1 (CA)
Inventor: ODA DWIGHT N
IPC: G01S17/14
Filed: 1996-05-24
Abstract: A high-speed data register (11) for storing a series of data values received at a high-speed clock rate (RCCK) and including a first set of pipelined latches (17, 19, 21) and a second set of pipelined latches (23, 25, 27). Control circuitry (29) loads the received data values alternately into said first set of latches (17, 19, 21) and said second set of latches (23, 25, 27) from an input or "last" register (13), which stores the last data value received by the data register (11). Data values thus enter the register (11) at the high-speed clock (RCCK) rate but are loaded into each of the first and second set of latches at one-half that rate.

Title: Method and apparatus for recycling iron and steel industry waste
Inventor: ISHIKAWA YOSHITAKA
IPC: F27B7/02
Filed: 1996-12-11
Abstract: In a method of recycling iron and steel industry waste (1-1, 1-2) by processing the waste (1-1, 1-2) as an object substance by the use of a rotary kiln (7), the object substance is changed into a valuable material while the object substance travels within the rotary kiln (7) from an upstream side to a downstream side.  The object substance is heated on the upstream side of the rotary kiln (7) within a reducing atmosphere to be reduced and molten into a reduced and molten product.          The reduced and molten product is quickly sent to the downstream side without being adhered to an internal wall of the rotary kiln (7).  The valuable material is extracted from the reduced and molten product which may be directly discharged out of the rotary kiln or which may be discharged after the reduced and molten product is once kept in a basin formed in the vicinity of the downstream side of the rotary kiln (7).

Title: Cast steel cut length optimization
Inventor: KELLAMS JAMES M
IPC: G06Q10/00
Filed: 1996-08-02
Abstract: A continuous steel caster (100) uses cut length optimization to minimize the amount of scrap steel in cutting a steel strand (120; 510; 520; 530; 540) into blooms with a traveling torch cut-off station (136).  The steel strand is cut to produce at least one bloom (514; 524; 534; 544) having a determined cut length.  The length for a next-to-last bloom (515; 525; 535; 545) is determined (416; 602-630) such that the next-to-last length is within a predetermined range of cut lengths and such that the next-to-last bloom may be cut into a number of billets each having a billet length within a predetermined range of billet lengths.  The length for a last bloom (516; 526; 536; 546) is also determined (416; 602-630) such that the last length is within a predetermined range of cut lengths and such that the last bloom may be cut into a number of billets each having a billet length within the predetermined range of billet lengths.  The next-to-last length and the last length are determined to minimize the amount of scrap steel remaining from the strand and may be adjusted by adding at least one predetermined submultiple length from the next-to-last length to the last length such that the next-to-last length and the last length are each greater than a predetermined minimum length.  The steel strand is cut to produce the next-to-last bloom having the next-to-last length and to produce the last bloom having the last length.

Inventor: HELSTERN ROBERT P
IPC: F21K99/00
Filed: 1997-08-12
Abstract: An improved apparatus for illuminating a display, such as a lens, includes a source of nonwhite light of a first color at an energy level which can be perceived by the human eye. The nonwhite light of a first color is reflected from a reflector to obtain white light. In one embodiment of the invention, the nonwhite light source was a solid state device (light emitting diode) which produced blue light at a high-energy level and green and red light at relatively low energy levels with the result that the green and red light could not be perceived by a human eye simultaneously with the blue light. The light from the solid state light source was reflected from a reflector having a gold (yellow) reflecting surface. The light reflected from the reflecting surface interfered with light emitted directly form the solid state light source with a chromatic shift of light energy. The resulting light from the reflector was white light.

Abstract: An apparatus for curing the web bonding adhesive and drying the corrugated paperboard web utilizes a top heating module contacting the upper face surface of the paperboard web for simultaneously heating the paperboard web along with a series of lower heating units.  The top heating module includes of a series of internal heating elements.  The heating elements are preferably tubes which receive a supply heated gas or liquid and transfer the heat contained therein to a heat exchange fluid within the module.  The heat from the heat exchange fluid is then transferred to the paperboard web through a web-conforming contact member.  As the paperboard passes through the double backer, the combination of the top heating module and the lower heating units cure the adhesive bonds in the paperboard web.  The web-conforming contact member preferably comprises a thin metal membrane and the heat exchange fluid is a liquid. Heat transfer and uniform contact is achieved by hydrostatic pressure of the liquid acting through the membrane against the web.

Abstract: In a method for producing index prints from photographic originals, each of the photographic originals is photoelectrically scanned in a scanning station of a photographic printer by a color- sensitive scanning system of low to medium local resolution in a plurality of first scanning regions. Using the scanning data, a digital color data set is determined for each original, with the aid of which set a digital representation of the picture content of the original is prepared for each original. The individual digital representations are grouped into a digital composite picture, from which an index print can be produced by an output device. The originals are alsophotoelectrically scanned in a scanning station by a locally high-resolution density scanner in a  plurality of second scanning regions. From the scanning data of the density scanner, a digital density data set for each original is determined, which includes density data representative of the original and which has a higher local resolution than the color data set.  In producing the digital representation of the picture content of the respective photographic original, both the associated color data set and the associated density data set are used.

Abstract: Corps de chauffe à air frais comportant un corps (2) contenant une voie d'écoulement (25) d'air vicié et une voie d'écoulement (14) d'air frais. Des dérivés de gaz obtenus après combustion provenant d'un brûleur à gaz (29) sont mélangés avec l'air frais pour réchauffer celui-ci à une température souhaitée avant qu'il ne soit évacué dans une enceinte. Les deux voies s'étendent à travers un échangeur de chaleur (15) et le débit de circulation d'air vicié déplacé par un ventilateur (26) à travers le corps est sensiblement égal à celui d'air frais déplacé à travers ce même corps par un second ventilateur (21). Comme le débit de circulation d'air frais provenant du corps et introduit dans une enceinte correspond sensiblement à celui de l'air vicié provenant de l'enceinte, et comme la chaleur est transférée entre les deux écoulements d'air par l'échangeur de chaleur (15), un remplacement total de l'air dans l'enceinte à un rythme relativement soutenu peut être supporté d'une manière économiquement viable. La teneur en produits de combustion nocifs dans l'enceinte et la teneur en produits générés par le brûleur à gaz (29) peut ainsi être maintenue en-deçà des valeurs considérées comme nuisibles par les autorités sanitaires.
