Title: Method and apparatus in a fluid-operating system
Inventor: INGVAST HAAKAN
IPC: F15B21/044
Filed: 1994-04-27
Abstract: The operation conditions in a hydraulic system is to a high extent influenced if the condition of the hydraulic fluid is improved and if its content of air and water can be reduced. This patent application relates to a method concerning these facts. This is made possible partly by the fact that the active, working fluid in the system is kept separated from the passive fluid in the hydraulic tank, partly that the active oil in its circulation in the hydraulic system passes a hydraulically operated purification apparatus, purifying the fluid in a comprehensive way. Here air and water are separated by vacuum treatment and the apparatus is also provided with a filter absorbing particles.
Patent CA-2164209-A1 (CA)
Title: Quick connect and disconnect electrical terminal
Inventor: VON RORETZ PHILIP
IPC: H01R4/48
Filed: 1994-05-06
Abstract: A first contact, made of a spring-like material, extends into a housing through the bottom end thereof and adjacent the right end of the housing such that a first portion of the first contact extends into the housing and a second portion extends out of the housing, the first portion being bent back upon itself within the housing. A second contact, also made of a spring-like material, also extends into the housing through the bottom end and adjacent n left end of the housing, once again, such that a first portion of the first contact extends into the housing and a second portion of the second contact extends out of the housing the first portion of the second contact also being bent back upon itself within the housing. Thus, the two contacts are substantially in the form of an M disconnected at the tip of the apex thereof. An opening extends into the housing from its top end communicating with the apex so that, when an electrical wire is inserted, through the opening, into the housing, it spreads apart the ends of the contacts forming the apex of the M against spring bias so that, when the wire has been inserted, the spring action of the contacts will pressingly engage the electrical wire. Finger operated means are provided for separating the contacts when a wire is held therebetween whereby to release the wire from removal from the electrical terminal.

Patent CA-2170440-A1 (CA)
Title: Self-Verifying Identification Card
Inventor: KRISTOL DAVID MORRIS
IPC: G06K17/00
Filed: 1996-02-27
Abstract: A self-verifying identification card having an image area which may contain a portrait, a finger print, a retinal image, or all of these together with an image signature which is derived from scanned intensity measurements taken from the image area.  In the verification process, the image is scanned and aligned with respect to reference points corresponding to the original printing process which created the card, and intensity values, their averages, or any other function are compared to information provided by the image signature.  Mathematical transformations, such as a one-way hash, an encryption, a compression algorithm, or a truth table may be used to encode the image signature. Alignment markers aid in scanning the image and the image signature.  The use of average values aids in reducing noise and the use of comparison functions makes the process less sensitive to variations among scanners.  The verification may be done at the point of a transaction, for a standalone system, or may be referred to a centralized data base in a networked system for further inquiry.  In a networked system the image signature may be stored in the database.

IPC: C22B21/06
Filed: 1995-02-03
Abstract: A method of and apparatus for treating molten metal to achieve effective removal of such unwanted inclusions as gases. alkali metals, entrained solids, and the like. The method comprises introducing molten metal into a trough, such as the trough provided between a melting furnace and a casting machine, providing at least one mechanically movable gas injector submerged within the metal in the trough and injecting a gas into the metal in a part of the trough forming a treatment zone through the injector(s) to form gas bubbles in the metal while moving the injector(s) mechanically to minimize bubble size and maximize distribution of the gas within the metal. The injectors are preferably rotated and comprise a rotor body having a cylindrical side surface and a bottom surface, at least three openings in the side surface spaced symmetrically around the rotor body, at least one opening in the bottom surface, and at least one internal passageway for gas delivery and an internal structure for interconnecting the openings in the side surface, the openings in the bottom surface and the internal passageway. The internal structure is adapted to cause gas bubbles emanating from the internal passageway to break up into finer bubbles and to cause a metal/gas mixture to issue from the openings in the side surface in a generally horizontal and radial manner.

Patent CA-2186094-A1 (CA)
Title: Dynamic load weighing system
Inventor: KOSTIUK WALTER
IPC: B65F3/02
Filed: 1996-09-20
Abstract: A method and device for determining the weight of a load while the load is being lifted by a lift or fork, typically in a lift-return cycle. Loadcell sensors are located close to the lift assembly with each loadcell sensor containing strain gauges attached to weigh posts to take measurements of forces acting in a multiple number of axes. The weight of the load can be calculated using these multi-axis measurements. The ratio of the forces acting in the different axes is used to correlate the measurements taken while the load is lifted and while the load is returned. The analog signals from the strain gauges are converted to digital signals by a analog-digital converter located in the loadcell sensor and transmitted to a computer which calculates the weight of the load with the use of a calibration table.

Patent CA-2189790-A1 (CA)
Inventor: YOO WAN-MOO
IPC: F16H47/08
Filed: 1996-11-06
Abstract: The present invention relates to a continuously variable transmission constructed in such a way that it can speed-change the power inputted to the input shaft into a normal operation mode, power mode or low speed mode according to the need and transmit the power to the output shaft even through all the gears remain engaged, and in addition reverse operation can also be effectuated in a simple way.       Reviewing the construction thereof, it is mainly composed of a speed change system, which receives power generated by an engine, speed changes it and transmits it to the output shaft, a speed change controlling system which automatically adjusts the rotational ratio to correspond to the condition of the load on the output shaft, and a reverse rotation system.       The present invention, comprises two planet gear sets each having a sun gear, ring gear and a carrier supporting a planet gear; a fuel ratio mode clutch and power mode clutch which can be selectively connected to the output shaft; a low speed brake provided on the power line connected between a turbine and the power mode clutch; and a reverse rotation system. Each constitutional element selected from the two planet gear sets is operatively connected to an impeller, turbine, power mode clutch and fuel ratio mode clutch respectively, and the power inputted through an input element selected from the two planet gear sets is changed into the required mode and transmitted to the output shaft.       Reviewing the operational characteristics, the present invention is constructed to output the input rotational force through different power transmitting paths by utilizing the power mode clutch and the fuel ratio mode clutch, and to transmit to the impeller the decelerated rotation always smaller than the input rotation at the time of operation of the fuel ratio mode clutch or power mode clutch Therefore, it is a characteristic of the present invention that it is constructed in such a way that the rotational force transmitted to the impeller is alway larger than the input torque.       In view of the effects, the present invention can obtain a large propulsion force, preferable performance, smooth and quiet operation, optimum fuel ratio, low speed mode speed change based on the fixed ratio, as well as engine braking effect, and especially, can speed-change steplessly at the time of reverse operation.
