Patent CA-2167998-A1 (CA)
Title: Twin post, telescoping jack hydraulic elevator system
Inventor: GILLILAND OSCAR
IPC: B66B9/04
Filed: 1996-01-24
Abstract: A twin post, telescoping jack hydraulic elevator system has a pair of dynamic sensors to determine when the jacks are out of synchronization, by determining any relative differences in height between the two intermediate cylinders. The elevator also includes static sensors to determine if one or both intermediate cylinders are more than a predetermined distance away from their normal positions when the car is stopped at each floor. The controller actuates a resynchronization if the distance between the intermediate jacks exceeds a first threshold, and shuts down the elevator if the distance exceeds a second threshold or if resynchronization demands are issued too often. Preferably, the static sensors are positioned to detect the seal housing at the top of the intermediate cylinder, which projects outwardly from the cylinder.
Patent CA-2168204-A1 (CA)
Inventor: MUCKENFUHS DELMAR RAY
IPC: A47K10/42
Filed: 1994-07-25
Abstract: The present invention pertains to improved pop-up dispensing systems in which edge portions (40, 50) of adjacent towels are non-parallel when the individual towel sheets (10) are interleaved and folded.  This new configuration provides improved pop-up dispensing reliability by providing a predictable, repeatable separation process. The overlapped area (80) formed by the overlapping end edges (40, 50) is tapered such that there is a point across the sheet width with the greatest overlap in the direction of the pulling force and a point across the sheet width with the least overlap in the direction of the pulling force. This configuration allow s the area of maximum overlap to pull the next sheet through the dispensing aperture at the same time that the sheet separation process is starting to take place at the area of least overlap. The separation process begins at the point of least overlap (100) and proceeds across the overlapping area (80) along a "separation front" toward the point of greatest overlap. When the overlapping area (80) is reduced to the extent that there is insufficient overlapping area to sustain the shear forces exerted, complete separation of the two sheets (10) will occur. The area of overlap (80), length of the separation front, and amounts of overlap at the point of greatest overlap can all be tailored to provide desired separation characterized for a particular aperture size, substrate, moistening agent, and moisture loading.

Filed: 1994-09-09
Abstract: L'invention se rapporte à un procédé pour la production de ferrosilicone dans un four à réduction électrique, grâce à l'utilisation de matériaux à teneur en fer, à teneur en quartz et à teneur en carbone. Ce four à réduction est, en plus des matériaux à teneur en Si, alimenté en agglomérats, qui remplacent au moins une partie du matériau à teneur en fer. L'agglomérat contient un mélange essentiellement homogène d'un matériau charbonneux et un composé de fer réductible, éventuellement du fer, de sorte que le rapport en poids entre le carbone et le fer dans les agglomérats réduits est compris entre 0,2/1 et 1,5/1, calculé sur la base de l'agglomérat réduit. Cet agglomérat assure l'absorption des gaz de SiO présents dans le four, qui normalement sont perdus avec les effluents gazeux sortant du four, ce qui permet d'accroître la production de Si et d'abaisser la consommation d'énergie.

Title: Aircraft instruments
Inventor: MOORE JAMES FREDERICK
IPC: G05D1/08
Filed: 1996-04-25
Abstract: The present invention relates to an aircraft instrument for reducing the risk of tail strike during aircraft take-off. The instrument receives an input from a pitch angle sensor and derives a signal indicative of rate of change of pitch angle. The instrument includes a comparator receiving the rate of change of pitch angle signal and signals from reference sources indicative of maximum and minimum rates of change of pitch angle. The instrument display is turned on when the aircraft nose gear lifts offthe runway and displays a stationary symbol as long as rate of change of pitch angle is within safe limits. When rate of change of pitch angle falls outside these limits, the display changes so that the symbol moves to warn the pilot. After the aircraft has reached a certain height, the instrument display is turned off.

Patent CA-2182498-A1 (CA)
Title: Fusion proteins that include antibody and nonantibody portions
Inventor: LAROCHELLE WILLIAM J
IPC: C07K19/00
Filed: 1995-02-01
Abstract: The high affinity which is characteristic of homodimers of IgG heavy chains is achieved, along with favorable secretion and flexibility/adaptability properties, in a fusion protein that has a nonantibody portion, comprised of an effector domain, joined to the aminoterminal end of an IgG-derived sequence consisting of a hinge:CH2:CH3 segment which lacks a CH1 domain, with a heterologous signal peptide preferably provided upstream of the nonantibody portion. Chimeric molecules of this structure can be secreted readily in stable form by mammalian cells transfected with DNA encoding the molecule, and are amenable to rapid, efficient purification to homogeneity, for example, using protein A. These molecules are effective substitutes for monoclonal antibodies in contexts such as flow cytometry, immunohistochemistry, immunoprecipitation and ELISAs. A fusion protein as described also can be used in screening for agonists and antagonists to the cognate binding partner of the nonantibody portion of the fusion protein. Moreover, chimeric molecules in which the nonantibody portion contains a growth factor domain are internalized, essentially like the natural growth factor, in contrast to the situation that generally pertains with respect to antibodies which are directed to external receptor domains.

Patent CA-2187096-A1 (CA)
Title: Three-phase electric machine with interlaced conductor layers
Inventor: HILL WOLFGANG
IPC: H02K3/12
Filed: 1995-04-05
Abstract: In prior art three-phase electric machines with a layered winding, the conductor elements either make non-optimum use of the space in the slot or the conductors for each phase are in the form of large elements designed to be fitted into each other and whose manufacture is complicated and costly.  The invention calls for the conductors (5-7) for each phase in the three-phase conductor layer (11) to be identical in construction and for the construction to be repeated every four pole pitches.  While the phase conductors (5-7) occupy the full height of the layer within the magnetic field, two phase conductors (5-7) superposed one above the other in the slot share the space at the coil ends (9).  At the slot exit, the conductor cross-section increases and only later, at the coil end (9), halved from only one side at each passage through the coil end.  In order to alternate the layer halves, contact surfaces are available which are large in comparison to the conductor cross-section and the two winding ends (9) are uniformly utilized by virtue of the plaiting of the layers.  The production of three-phase conductor layers by laying alternate conducting and insulating layers is particularly suitable for small electromagnetic machines, giving uniform space utilization and hence high effectiveness and a high power density at low cost, and requiring only a few operations.
