Patent CA-2004937-A1 (CA)
Inventor: THURIES EDMOND
IPC: H01H3/30
Filed: 1989-12-08
Abstract: The invention relates to controlling a circuit breaker by means of a drive mechanism circuit for operating a circuit breaker by rotating a main operating shaft (4). The drive mechanism comprises a trigger circuit breaker drive mechanism (1) delivering considerably less power than that required for operating the circuit breaker, and associated with an assembly including a disengagement first spring (6), an engagement second spring (12), and a recocking motor (14) for recocking the springs which are disposed, on being released, to drive the main shaft (4) through 180 DEG , with the release of the springs being controlled by motion of an outlet member (2) of the trigger drive mechanism (1). The invention is applicable to the operating circuit breakers.

Abstract: IN THE  CANADIAN    PATENT AND TRADEMARK OFFICE         PATENT APPLICATION   entitled:       A MECHANICAL STABILIZATION SYSTEM USING                 COUNTER-ROTATION AND A SINGLE MOTOR in the name of: G. ATLAS assignee:       SOCIETE EUROPEENNE DE PROPULSION                      ABSTRACT OF THE DISCLOSURE      The system for stabilizing a support comprises a working rotor mounted on the support by frictionless bearings and fixed to a working member for which at least one parameter associated with the rotation of the working rotor is variable as a function of time.  A nested reaction rotor is mounted concentrically relative to the working rotor by frictionless bearings such as magnetic bearings or gas bearings and it supports a reaction inertia member.  A single servo-controlled electric motor is interposed between the working rotor and the reaction rotor in order to drive the working rotor and the reaction rotor in opposite directions in such a manner that the torque disturbances generated on the support by the motion of the working rotor are cancelled by the simultaneous reaction motion of the reaction rotor, with the ratio of the speeds of the working rotor and the reaction rotor being such that the total angular momentum of the working rotor and of the reaction rotor is kept equal to zero.

Title: Plastic grave marker
Inventor: SIMPSON RONALD C
IPC: G09F19/00
Filed: 1990-03-29
Abstract: ABSTRACT OF THE DISCLOSURE      A novel plastic grave marker has an integral rear socket to receive the head of a stake.  The socket has side walls, rear wall and top wall to receive engageably the top portion of the stake.  The socket walls are desirably integral with the rest of the marker.  The grave marker is cast or molded in one piece, which confers additional strength on the socket.  Most prior art grave markers either had to be assembled before driving into the ground, or afterwards and are considerably more complicated.  The grave marker front has marked off areas to receive indicia, such as name of deceased, birth and death dates, and the name of the funeral home or funeral director.  The plastic is not only practical, but is also esthetic.

Filed: 1990-06-05
Abstract: Abstract of the Disclosure A microlithographic process of fabricating electronic components, such as, for example, integrated circuit chips and thin film read/write heads for computer disk systems, in which a laser is used to etch features defined by a mask.  The laser is selected whose radiation will be absorbed by the workpiece being etched, and the masking material is selected so as to be highly reflective of the laser radiation.  The masking material is patterned in a conventional manner so as to expose the portions of the workpiece material to be etched.  When the laser is directed to the workpiece, the laser radiation etches the portions of the workpiece not protected by the mask.  A preferred process of scanning with a laser is disclosed.  Etching may be improved if performed under a liquid transparent to the laser radiation.

Title: Method of reprocessing zinc- and lead-containing residues from metallurgical plants
Inventor: HIRSCH MARTIN
IPC: C22B7/02
Filed: 1990-12-20
Abstract: Zinc- and lead-containing residues from metallurgical plants are reprocessed by a thermal treatment in a circulating fluidized bed system. A major part of the heat demand is satisfied by a com-bustion of solid carbon in the fluidized bed reactor of the circulating fluidized bed system. A reducing fluidizing gas, which is virtually free of free oxygen, is fed to the lower part of the fluidized bed reactor, A solid carbon content from 5 to 30 % is adjusted in the fluidized bed in the lower portion of the fluid-ized bed reactor, which is supplied in its upper por-tion with oxygen-containing gases and in which CO2 is formed only at such a rate that zinc metal is not reoxidized. Substantially all solids are removed in a recycling cyclone from the suspension which bas been discharged and are recycled. The gas is cooled to a temperature at which zinc metal is oxidized to ZnO.      The dustlike zinc compounds and lead compounds are removed from the gas,

IPC: G06F3/033
Filed: 1990-04-02
Abstract: A computer system employs an integrated keyboard and pointing device (FIG. 9) to allow user input of alpha-numeric (typing) information (94, FIG. 12), pointing direction information (174, FIG.  12) and pointing event information (178, FIG. 12) without moving the user's hands from the usual typing position on the keyboard.  The new system has typing and pointing modes of operation (FIG.  10). In the pointing mode, preassigned keyswitches are used to input pointing events, cursor speed changes, and other modifications to the system's operation (182, FIG. 12). All such modifications are transparent to the operating system and application software because they are processed at keyboard interrupt level (162, FIG.  11).

Title: Method and tape for joining paper webs
Inventor: PITKANEN SAMI
IPC: C09J7/02
Filed: 1990-01-12
Abstract: This invention relates to a method and tape for joining paper webs. In paper production, a paper web is accidentally broken or cut, in which case the ends are joined together by means of a tape.  In the known junction, the ends of the webs are located one on top of the other, and there is a two-sided tape therebetween. On account of faults in work, the paper does not always completely cover the tape, wherefore the junction point in the roll will adhere to the paper on top and underneath, which will result in a web rupture. This disadvantage can be avoided by using one-sided tape (1) whose protective film is divided into two parts (5, 6), whereby a butt joint can be made which involves no danger of sticking.
