Patent CA-2140200-C (CA)
Inventor: PURANEN JUSSI ERKKI TAPANI
IPC: B27L5/02
Filed: 1995-01-13
Granted: 1998-07-07
Abstract: A method of controlling the clearance angle of a veneer lathe knife in a veneer lathe having a knife holder beam rotatably mounted on a knife carrier.   The beam's vibration frequency is continuously measured and compared with a stored representation of a vibration frequency range (about 50-200 Hz.) characteristic of disruption of the veneer peeling operation.  If the comparison reveals that the measured vibration frequency is within the characteristic disruptive range, the beam is rotatably adjusted until the comparison reveals that the measured vibration frequency no longer lies within the disruptive range.  Usually, the adjustment accelerates lowering of the beam in order to make the knife clearance angle less positive.

Patent CA-2151845-C (CA)

Granted: 1999-05-04
Abstract: A penile engorgement valve has a looped rod (1) with an arcuate center section (2) positioned on a top base surface of a male penis (3). Opposite side sections (5) of the looped rod are extendable arcuately at opposite sides of the male penis and juxtaposed at a fulcrum curve (6) in each of the opposite side sections. A lever arm (7) is extended from the fulcrum curve in each juxtaposed side section and attachable to a tension member (11). The tension member is anchored to a hip section and rearward of a user. Tension from the tension member is applied to the lever arms in a direction towards the hip section of the user. The tension results in pressure on the fulcrum curves and on the arcuately looped center. Blood flows into the penis in arteries (16) and returns in flow out from the penis in veins (15) at the top of the penis in a pubic area (4) where the arcuately looped center is positioned and at opposite bottom sides of the penis in a perineal area (8) where the fulcrum curves are positioned. Flow of blood out from the penis is restricted relatively more than flow of blood into the penis by a valvular effect resulting from relatively greater collapsibility of the veins than of the arteries from the pressure applied. This enhances penile engorgement and turbidity for sexual intercourse. Pressure adjustment and cushioning on of the looped rod are included.

Abstract: A relatively hygienic dispenser is provided for dispensing particulate matter such as bulk foods, gum drops or even hardware such as nuts and bolts. A dispenser mechanism is attached to a storage bin or receptacle. The material, typically food or sticky candy, falls toward dispenser module due to gravity. The dispenser has a four sided roughly rectangular, variable geometry passageway. Two opposed sides of the passageway are rigid, and the other two opposed sides are flexible. A scoop is pivotally mounted to the two rigid walls and extends across the passageway between them. The two lobed scoop accepts material from the receptacle, is turned either clockwise or counter-clockwise, and discharges material, presumably to a waiting container.  The scoop turns between, and in contact with, the two spring-loaded sides, or skirts, and two flexible scraper walls. The scrapers discourage materials from sticking to the outside of the scoop, and the flexible skirts press close to the sides of the scoop as it is turned, limiting flow, yet may flex to discourage crushing or shearing of gummy particles. This permits control of the rate of flow of bulk food materials in a relatively hygienic manner.

Abstract: A method of automatically transferring contact lenses from a plurality of cups good positioned at a first location to a plurality of packages positioned at a second location wherein each good cup contains a transferable contact lens for placement in an individual blister package comprises a step of communicating positional information of good cup locations to a robotic device having an arm with one or more end effectors thereon, each end effector having a tip in connection with a vacuum and air pressure supply device, each end effector independently moveable with respect to the arm. Then, steps of applying a vacuum to the end effector tip to enable pick-up of a transferable lens from a cup located at a good cup location, and, controlling the robot to effect positioning of one end effector tip within the cup having the transferable lens therein to pick up the lens are performed. A further step includes controlling the robot to remove the end effector tip from the good cup location to position it within a blister package cavity, and finally, removing the vacuum and applying air pressure to the end effector tip to deposit the lens from the effector tip into a blister package cavity.

Abstract: A turn coordination inhibit system (150) inhibits a rotary winged aircraft c ontrol system from operating in an automatic turn coordination mode when a pilot desired to perform a sideslip maneuver, e.g.,  a flat turn. When automatic turn coordination is not en gaged (132, 212, 215), e.g., the aircraft is not in a coordinated turn, and either  aircraft bank angle (119) exceeds an inhibit threshold magnitude (210) or a pilot yaw command provided by a pilot sidearm controller (155) ex ceeds a minimum threshold value (243), e.g., the sidearm controller is out of detent in the yaw axis, automatic turn coordination is inhibited (152). Automatic turn coordination remains inh ibited until both aircraft bank angle falls below a reset threshold magnitude (230)  and the sidearm controller is back in the detent positi on for the yaw axis (243).

Abstract: Methods and apparatus are described for recognizing wellbore telemetry signals, wherein a received analog telemetry signal is compared to a number of possible analog signals. The probability of representing the received signal is determined for each of the possible analog signals. By selecting the signal with the highest probability, the received signal is demodulated. For calculating the probability, Bayes' method or any equivalent thereof is used. In variants, this probabilistic method is used to determine the synchronization point of the telemetry signal and for controlling the noise removal therefrom. The method and apparatus show increased accuracy in recognizing and demodulating the received signals.

Abstract: On décrit un système (31, 41, 32, 33) dans lequel un utilisateur modifie manuellement la qualité de périodes spécifiques d'une séquence vidéo (180) codée. Après le codage (50) automatique de cette séquence vidéo en un format numérique comprimé, une personne qui met en forme (31, 33) la séquence vidéo codée, réexamine la qualité de celle-ci et indique manuellement s'il faut modifier la qualité de périodes (180) spécifiques de cette séquence. Etant donné que le support d'information numérique, tel qu'un disque optique (84, 90), lequel mémorise la séquence vidéo codée, possède une capacité limitée de mémorisation, le nombre total de bits de la séquence vidéo (50) codée et la qualité de celle-ci sont limités. Un certain pourcentage de bits est enlevé de la séquence de temps et placé dans un groupe (368) de bits. Au moyen d'une fonction exponentielle (368), de nouveaux bits sont calculés et les bits placés dans le groupe sont distribués proportionnellement à des trames (376) vidéo, lesquelles doivent être ensuite vérifiées (394) et éventuellement réglées (398, 400), afin d'empêcher le sous-dépassement de capacité de la mémoire tampon vidéo.
