Patent CA-2089458-C (CA)
Title: System comprising a container having a slit valve as a venting valve and a liquid contained in said container
Inventor: BILANI NADI
IPC: B65D47/20
Filed: 1993-02-12
Granted: 1998-08-04
Abstract: In a system comprising a container and a liquid contained therein that builds up a gas or vapour pressure, a sealing valve having a concave shaped portion and a slit extending through said portion, allows venting of the vapour from the container to the ambient at a predetermined vapour threshold pressure.  The vapour threshold pressure at which the slit opens for venting can be adjusted by valve restraining means which are preferably formed by a protrusion at the inside of a cap covering the sealing valve.  The vapour threshold pressure at which venting takes place, can to a large extent be adjusted without affecting the dispensing characteristics of the valve.

Inventor: BUISMAN CEES J N
IPC: C02F101/10
Filed: 1992-04-03
Granted: 2000-03-21
Abstract: The invention provides a method for removing sulphur compounds from water by anaerobic reduction of the sulphur compounds to sulphide, followed by partial oxidation of the sulphide to elementary sulphur. The anaerobic reduction is carried out at elevated temperature, either continuously at a temperature of 45-70 °C, or periodically at a temperature of 55-100 °C. If the reduction is carried out periodically, a single rise in temperature for a few hours to several days over a period of 3-6 months can suffice. The method is particularly applicable to the removal of sulphate, sulphite and thiosulphate.
Patent CA-2107875-C (CA)
Inventor: KIRSCH JASON ROBERT
IPC: A01B49/02
Filed: 1993-10-06
Granted: 2002-08-20
Abstract: A new combination farm implement is disclosed. A cultivator is equipped with detachable mounted harrows and detachable packers. When the cultivator is used for direct seeding, narrow openers cut through the earth, and seed, transported from an air seeder by pneumatic means, is placed immediately behind the openers. Thereafter a series of packers, mounted to the rear of the cultivator, pack the seed. The invention lies in spring tensioned support arms which support the packers or harrows. Through various adjustments, these support arms can generate packing pressures from .5 psi to 3.5 psi, depending upon soil conditions. The same implement with the narrow openers and packers removed can be equipped with sweeps and mounted harrows and seed while cultivating to kill weeds or act as a general soil preparation device. The adjustable spring tensioned support arms are adjusted to relax downward pressure when the harrows are mounted in field operation. The unit as a whole, therefore, serves as a seeding or general tillage device, saving the operator extensive capital costs in farm machinery.

Title: Technique for plotting a variable-width signal in a fixed-width plot area
Inventor: TARAKI YOSUF M
IPC: G06F3/13
Filed: 1996-01-05
Granted: 2004-04-06
Abstract: A data acquisition device permits plotting of cylinder firing cycles, of varying-frequency, on a fixed-plot area of a CRT screen. Each cylinder firing cycle is sampled, at a constant sample rate, and consecutive sets of sample points, each containing a fixed number of sample points, is generated. On the basis of a unique data reduction technique triggered after the collection of each consecutive sample-point set, certain of the sample points considered superfluous are deleted from the set and the remaining appended to a temporary buffer. The sample-points in the temporary buffer further undergo reduction of the sample points when certain conditions occur, such as buffer full, at which time certain ones are discarded and others are kept. At the end of a cylinder firing cycle, the remaining points are further reduced and a final-set is generated, representative of a full cylinder firing waveform, consisting of sample points equal in number to the plot-width of the CRT screen.

Title: Method for producing molten pig iron
Inventor: DEN HARTOG HUIBERT WILLEM
IPC: C21B13/00
Filed: 1996-02-07
Granted: 2000-05-02
Abstract: A process for producing molten pig iron uses direct reduction of iron ore in a pre-reduction stage followed by a final reduction stage.    In the pre-reduction stage iron ore is pre-reduced in a melting cyclone by means of a reducing process gas originating from the final reduction stage.  A post combustion occurs in the reducing process gas in the melting cyclone so that said iron ore in said melting cyclone is at least partly melted.  The partly melted iron ore passes downwardly into a metallurgical vessel situated beneath the cyclone in which the final reduction takes place by supply of coal and oxygen, thereby forming a reducing process gas.  A partial post-combustion occurs in the reducing process gas in the metallurgical vessel by means of said oxygen supplied thereto.  The post-combustion ratio of the gas on exiting the metallurgical vessel is not more than 0.55.          The coal is supplied directly into the slag layer so that said partial post-combustion in said metallurgical vessel is at least partly effected in the slag layer.

Granted: 2001-05-01
Abstract: An apparatus and method is provided that supports continuous media for conventional networked workstations and PC's. Described are user-level mechanisms and policies designed to give good, efficient multimedia service under the mild assumption that the operating system provides a preemptive real-time scheduling class that can be used to give CPU cycles to the multimedia processesin preference to other processes that are not time sensitive. There are no modifications to the operating system kernel and isochronous networks are not required. It suffices for an application to state that it wants to play a particular stream of a type known to the server (e.g. a file containing MPEG-1 video 32Ox240 pixels, 8-bit color, 30 frames per second), or for the application to specify a frame rate and an index describing the offset of each frame in a file.
