Title: Helicoptere a levier
Inventor: DUMONT RICHARD
IPC: B64C27/52
Filed: 2000-05-02
Abstract: Les hélicoptères sont des appareils relativements complexes tant du point de vue technique par leur construction que pour leur opération qui nécessite de la part du pilote beaucoup de concentration et de coordination.  La présente invention permet d'amoindrir tous ces aspects en limitant le nombre d'éléments constituant l'appareil et en simplifiant les con- trôles.  Ainsi l'hélicoptère à levier tel que présenté ici est constitué de trois éléments principaux: soit une structure de base appelée la cellule supportant une unité monolithique permettant le vol nommée le groupe rotors, les deux étants reliés et contrôlés par un seul lien, désigné sous le nom de levier de contrôle.  Le pilote utilise donc la force physique de ses bras pour transmettre les commandes, alors que l'ensemble des contrôles sont actionnés par l'usage des mains.

Patent CA-2308211-A1 (CA)
Title: Composite trellis system and method
Inventor: HUFF RONALD J
IPC: H04L27/00
Filed: 1998-10-29
Abstract: This invention provides means for pro-cessing a received digitally-modulated carrier signal to coherently demodulate or, for some applications, coherently demodulate and de-code said signal when the signal's phase has an undesired component and/or to generate successive estimated values of said undesired phase of the received signal. The signal pro-cessed is partially represented by a compos-ite trellis diagram formed by combining mul-tiple component trellis diagrams which are phase-displaced versions of a root trellis di-agram. Desired variations in signal param-eter values that result from modulating the signal effect transitions between states within the root trellis diagram. For some embod-iments of this invention, transitions between states within different component trellis dia-grams for which phase values are proximate, trellis coupling transitions, are incorporated into the composite trellis diagram in a periodic manner to accommodate undesired variations in the received signal's phase for which the rate of change in phase is adequately small rel-ative to the modulation rate but not otherwise restricted. The received signal is processed in accord with the composite trellis diagram through appropriate application of the Viterbi maximum likelihood processing algorithm or any sub-optimum variant, derivative or counterpart thereof. A demodulated data sequence and/or a sequence of estimated values of the received signal's phase are derived from appropriately structured path history values generated for the multiple states in the composite trellis diagram. The received signal processed may have a continuous envelope or may be comprised of a succession of non-overlapping signal bursts which originate at one or more transmit locations as in a TDMA system.

Title: Motorized operator for casement windows
Inventor: LABARRE ANDRE
IPC: E05F15/614
Filed: 2000-05-19
Abstract: A motorized operator for opening and closing a window sash relative to a window frame via an arm mechanism connected to the window frame and being adapted to be installed in a cavity defined in the window frame. The operator comprises a motor, a drive axle rotated by the motor, and first and second gears in meshed engagement. The first gear is mounted on the drive axle, while the second gear is mounted to the arm mechanism such that motorized rotation of the first gear rotatably drives the second gear thereby causing the arm mechanism to pivot for opening and closing the window sash. A manual operator is adapted to disengage the first and second gears from one another while becoming engaged to the second gear for manually rotating the second gear and so manually operate the arm mechanism. The manual operator comprises a handle and a manual actuator which includes a sprocket. The manual actuator is engageable on the drive axle for selectively displacing the first gear along the drive axle and cause the latter to disengage from the second gear while the sprocket of the manual actuator becomes engaged to the second gear, whereby a rotation of the manual actuator by way of the handle causes rotation of the sprocket and of the second gear and thus also a pivot of the arm mechanism.

Filed: 1999-09-24
Abstract: A loop gain of an AGC circuit (7) and a loop gain of a clock regenerative circuit (6) are kept increased (an amplifier gain is increased or a loop filter is set to a wide band) until a synchronizing signal (a segment synchronizing signal or field synchronizing signal) is detected. After a synchronizing signal is detected, a loop gain of the AGC circuit (7) and a loop gain of the clock regenerative circuit (6) are reduced (an amplifier gain is decreased or the loop filter is set to a narrow band). The above arrangements can make compatible the shortening of time required for completing a converging processing in the AGC circuit and the clock regenerative circuit with the increasing of ghost interference removal and an accurate clock regeneration.

Patent CA-2312727-A1 (CA)
Inventor: MEHLMANN ALEXANDER
IPC: A23L3/3436
Filed: 1998-12-02
Abstract: For the storage of foodstuffs which are susceptible to oxidative degradation it is proposed to use powdered metal - and especially aluminium - in wetcorrosion compositions using strong corrosion agents, and specifically materials (such as strong acids and strong alkalis) that will reduce the pH to well below 4 or increase it to well above 9. More particularly, it is proposed that the metal and a large-surface-area, reaction-site material be utilised in a very finely powdered form, and especially one in which a significant proportion of the particles are deformed, possibly with fracturing. The compositions can be dispersed within a water- and oxygen-permeable sheet that can be disposed in actual, direct contact with the oxygen-sensitive substance to be protected.

Abstract: A bendable tubular container for storing and mixing two compositions which must be kept separate until being mixed together at or near the time of use. The container comprising flexible tubular walls, a cap at one end through which the contents of the container are emptied defined as the top portion, and a permanent pinch seal at the other end, defined as the bottom portion. The interior temporary seal separates the top portion and the bottom portion into two compartments. The interior temporary seal is situated on an opposite plane to the permanent pinch seal, thereby maximizing the volume capacity of each compartment. The container is bent along the crease of the interior temporary seal whereby the two compartments are positioned adjacent to one another and fastened together by a temporary contact seal.   Two compositions can be deposited into the two separate compartments and later mixed together by unbending and squeezing the container thereby causing the interior temporary seal to break open and the contents of the two compartments to be mixed together. The contents can be mixed together more uniformly by shaking the container.

Title: Signal production circuit and display device using the same
Inventor: NAKAMURA EIJI
IPC: G09G3/00
Filed: 2000-10-11
Abstract: A serial-to-parallel converter circuit is constructed of a plurality of D flip-flops receiving, as a clock signal, data in a single signal of serial data stored in a ROM. Each D flip-flop transmits "high" data to a next stage through a latch operation every time a piece of the data is read from the ROM. The plurality of D flip-flops converts the signal of serial data to parallel data by producing output signals as control signals. According to this arrangement, a signal production circuit and a display device incorporating it become available which allow for a reduction in the capacity, cost, and dimensions of the storage means, and also in the wiring and substrate areas required around the storage means, through more efficient use of the data stored in the storage means.
