Patent CA-2188787-C (CA)
Inventor: STEWART MARK FREDERICK
IPC: F41J3/00

Abstract: Cible pour fléchettes a embout de métal dur comportant une toile rigide conductrice (7) composé d'anneaux concentriques coupant des rayons partant du second anneau à partir du centre. Les rayons délimitent 20 secteurs et les anneaux, quatre segments par secteur. L'anneau central et le suivant constituent également des segments. Des blocs conducteurs faits de coupelles d'aluminium ou de zinc et munis de contacts saillant du fond et contenant du liège caoutchouté remplissent les segments de la toile. Sous chaque coupelle se trouve un coussin de mousse de silicone évidé entre les contacts et un tampon disposé sur un circuit imprimé. Chacun des tampons est relié à un circuit détectant l'impact d'une fléchette sur un insert, ce qui entraîne le glissement de la coupelle correspondante à l'intérieur de la toile son contact avec le tampon. Grâce à des capteurs piézo-électriques, le circuit détermine si une fléchette a frappé sur la cible ou à proximité et vérifie si la cible a touché un segment, ce qui indique un coup au but sur la cible, sans quoi la cible indique que la fléchette l'a manquée. Le circuit détecte par ailleurs le sens de rotation de la cible et établit en conséquence le score de base des segments, ce qui permet de repositionner les segments à usage intense dans les secteurs à usage rare en faisant tourner périodiquement la cible.

Abstract: A high-pressure cleaning appliance has an electric motor arranged in a housing, a high-pressure pump arranged in a housing with at least one piston that enters a sealed pumping chamber and a swash plate carried on a motor shaft that extends out of the housing of the electric motor. The pistons of the high-pressure pump are elastically supported on the swash plate. In order to electrically insulate the area of the swash plate drive, the transition through the swash plate from the motor shaft to the pistons is electrically interrupted by an intermediate layer of electrically insulating material.

Abstract: A process for preparing storable vegetable juice comprising crushing vegetables to extract juice, adding an organic acid to the vegetable juice, and treating this vegetable juice with a weakly basic anion exchange resin on which an organic acid has previously been adsorbed and a food containing a vegetable juice prepared by the process.     The process can produce vegetable juice which can be stored at room temperature, produces no bad odor when stored at room temperature, and is free from a resin odor which has been unavoidable when a weakly basic anion exchange resin was used.

Filed: 1996-01-16
Granted: 2006-11-07
Abstract: This application is directed to fluorinated oxetane monomers and methods for making the monomers.    The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivatives of 3-hydroxymethyl-3-methyloxetane pre-monomers.

Title: Optical sampling by modulating a pulse train
Inventor: HADJIFOTIOU ANAGNOSTIS
IPC: H04L7/00
Filed: 1997-11-26
Granted: 2002-01-15
Abstract: An interferometer, such as a Mach-Zehnder type is fed with a pulse train. One arm is fed with a data stream, so as to modulate the pulse train according to the data stream. This enables the data stream to be regenerated, or sampled without converting from optical form into electrical form. Thus all optical regeneration, multiplexing, demultiplexing or retiming to remove jitter, can be achieved. An optical amplifier (20) in one arm of the interferometer enables the interference condition of the interferometer to be varied, to cause the pulse train to be modulated by the data.

Abstract: A system is provided for controlling a D-C motor which is constructed to propel a golf car.   The motor is controlled  to  provide  performance  according  to  a predetermined  field  current  map  which  calls  for  a particular   performance    response    to    specified performance  events.     The  performance  events  are detected by sensing actual speed and armature current and   the   performance   response   is   triggered   by adjustment  of  the  field  current.  A performance map correlating  actual  speed  to  various  events  and specifying the field current response is designed for the  motor  used.    In  addition  an  armature  current performance map is  similarly constructed correlating armature current to particular performance events.

Title: Technique de surveillance des defaillances pour controleurs logiques programmables

Granted: 2000-04-25
Abstract: L'invention porte sur un circuit isolé de surveillance des défaillances constatées sur le port c.a. d'un module c.a. E/S pour un contrôleur logique programmable. Un circuit en pont est relié en série à un fusible et à un coupleur optique. Lorsque le fusible, monté en série avec la ligne d'entrée c.a. saute, le coupleur optique produit une tension égale à la moitié de celle correspondant au fonctionnement normal, ce qui élève la tension de l'un des deux comparateurs et provoque l'allumage d'une DEL indiquant que le fusible a sauté. Si la ligne d'entrée c.a. est débranchée ou hors tension, le coupleur optique n'émet aucun signal, ce qui amène le second des optocoupleurs à produire un signal de sortie plus élevé et à allumer la seconde des DEL qui signale le fait. A aucun moment, et quelle que soit la défaillance, plus d'une DEL s'allume à la fois, et aucune des DEL ne s'allume en fonctionnement normal.

Granted: 2003-12-02
Abstract: An Extended Nip-type press (20) has a blanket (30) which passes over a shoe (22) which is urged against a backing roll (24) to form a press nip (56). A hydraulic system (70) and controller (94) provides for automatic continuous oscillation of the blanket (30) in the cross machine direction. The oscillation results in a region of high fatigue (58, 59) continuously moving over the blanket (30) surface so that the amount of time any particular region sees wear is minimized. Positioning of the heads (38, 42) to which the blanket (30) ends are mounted is controlled by hydraulic pistons (60, 62) mounted between a support beam (26) and the heads (38, 42). A controller (94) operates a valve (74) to reverse the direction of motion of the blanket (30) when sensors (92, 98) indicate one end of the blanket (30) has reached a stop (64, 80). A throttle valve (86) controls the rate at which hydraulic fluid is supplied to the cylinders (60, 62) which urge the head (38, 42) away from the shoe (22).
