Patent CA-2199164-C (CA)
Inventor: BEBERNES THOMAS DARYL
IPC: A01D41/14
Filed: 1997-03-04
Granted: 2000-05-16
Abstract: An agricultural implement includes a header or platform suspended from a main frame by a suspension permitting movement of the header between a lowered working position and a raised transport position.  The suspension includes single-acting float cylinders and a single-acting lift cylinder controlled by anelectrohydraulic control system including a programmable microprocessor in whicha signal representative of a minimum acceptable float pressure may be set. The microprocessor contains an electronic switch that couples a warning device lead to ground to effect energization of the warning device in response to the microprocessor receiving an electronic signal representative of a float circuit pressure below the minimum acceptable float pressure. In one embodiment, the microprocessor contains a timing device which is triggered whenever a control switch is connected to energize a "lower" signal lead the timing device being set to time out when sufficient time has elapsed to ensure that the header has reached its working position. The timing device works to suppress the signal representative of the float circuit pressure so that a premature energization of the warning device does not occur when a low float pressure is due to the header being elevated from the ground. In another embodiment, a normally open mechanical switch is connected in series with the electronic switch and is closed only when the header reaches its working position. Replenishing of float pressure to a desirable level may be done either manually or automatically once the low pressure warning device has been energized.

Granted: 2000-02-22
Abstract: A combined furnace limestone injection and dry scrubber flue gas desulfurization (FGD) system collects solids from the flue gas stream in first particulate collection means located downstream of an outlet of a convection pass of the furnace and upstream of the dry scrubber. The collected solids are diverted to the dry scrubber feed slurry preparation system to increase sulfur oxide species removal efficiency and sorbent utilization. The level of lime in the feed slurry provided to the dry scrubber is thus increased, which enhances removal of sulfur oxide species in the dry scrubber. The decreased particulate loading to the dry scrubber helps maintain a desired degree of free moisture in the flue gas stream entering the dry scrubber, which enhances sulfur oxide species removal both in the dry scrubber and downstream particulate collector, normally a baghouse.

Granted: 2006-08-15
Abstract: Procédés et instruments chirurgicaux pour la réalisation d'un pontage aortocoronarien à accès par orifices ou à thorax fermé dans le traitement de la coronaropathie multivasculaire. A la différence du pontage aortocoronarien normal à thorax ouvert qui exige une sternotomie médiane ou une autre thoracotomie macroscopique pour mettre à nu le coeur du malade, le pontage aortocoronarien à accès par orifices s'effectue au travers de petites incisions pratiquées dans les espaces intercostaux du malade, ce qui permet une forte réduction des douleurs et de la morbidité chez le malade. Des techniques de prise thoracoscopique ou laparoscopique permettent de préparer à la greffe les greffons de pontage artériel tels que les artères mammaires internes et/ou l'artère gastroépiploïque droite. Les greffes libres, par exemple une greffe de veine saphène ou une greffe artérielle libre, peuvent s'ajouter aux greffes artérielles in situ. On anastomose les vaisseaux greffés avec les artères coronaires sous visualisation directe au moyen d'un microscope cardioscopique introduit par un orifice d'accès intercostal. On utilise des instruments écarteurs pour manipuler le coeur à l'intérieur du thorax fermé du malade afin de mettre à nu chacune des artères coronaires en vue de la visualisation et de l'anastomose. On décrit un instrument de formation de tunnels et un instrument articulé de préhension pour la formation de tunnels, ces instruments étant destinés à modifier le parcours des vaisseaux greffés, ainsi qu'un écarteur en forme de doigt, un écarteur à ventouse, un écarteur à anse et un écarteur à boucle pour la manipulation du coeur. On décrit également un dispositif de refroidissement topique à accès par orifices destiné à améliorer la protection myocardique au cours de la procédure de pontage aortocoronarien à accès par orifices. En outre, on décrit une autre approche chirurgicale mettant en oeuvre une médiastinotomie antérieure.

Title: Device for forming a fully tied surgical knot
Inventor: SCHULZE DALE R
IPC: A61B17/04
Filed: 1997-12-16
Granted: 2006-07-04
Abstract: A device for forming a non-slip surgical knot for fastening tissue is disclosed. A partially tied knot which has a first loop and knot loops formed about the first loop to create a common loop core receiving the first loop is initially provided. The distal end of the suture filament from which the partially tied knot is made is passed through the tissue, and it is then fed through the first loop to form a tissue-fastening loop. When axial tension is applied on the proximal length of the suture filament while the knot loops are supported during the conversion step, the first loop and a portion of the suture filament are pulled through the common loop core. This eliminates the first loop and forms a distal loop positioned adjacent the common loop core. The device forms a non-slip knot, with a consistently high knot security without the need to provide a tension on the suture filament which exceeds the breaking strength of the suture.

Abstract: The invention relates to a composite floor structure (1) comprising a mortar layer (8) set by a mineral agent and a carrier plate (4) adjoining the lower surface of the mortar layer (8). The carrier plate (4) has upwardly projecting structural members (6) extending into the mortar (8). The dimensions of the mortar coating (U) over the structural members (6) are so low that the structures created in the mortar (8) by the structural members (6) represent weak areas. When stresses arise in the mortar layer (8), joint face assemblies connecting weak areas are formed to reduce stress in a uniform manner. By forming different joint face assemblies, a joint face structure is produced, wherein to reduce stress, the stress causing the mortar (8) to fracture only results in a low level of longitudinal change in each individual joint face. Consequently, each individual joint face only takes the form of a microcrack.

Abstract: Arcing faults are detected by a multi-channel arc fault detector in which each channel includes a bandpass filter having an assigned discrete passband which is non-overlapping with the passband of any of the other bandpass filters. Thus , the detector can discriminate an arcing fault which produces white noise and therefore generates an output from all of the bandpass filters simultaneously from a carrier signal which will only produce an output from one bandpass filter. The output of th e individual bandpass filters can be ANDed, for example, by comparators with a common pull up resistor, or by analog multipliers. The output of the arcing fault detector can be used to trip a circuit breaker.

Abstract: An electromechanical cylinder lock includes a lock body and a turnable lock cylinder and a locking mechanism inside the lock body. The locking mechanism normally prevents turning of the lock cylinder relative to the lock body and can be moved by means of a key of the lock to a releasing position allowing turning of the lock cylinder. The key for the lock includes a transmitter for transmitting an electronic code and the lock correspondingly includes a receiver for receiving and identifying the code of the key.      When the receiver detects the correct code the receiver enables mechanical opening of the lock by means of the key.      The lock includes a locking disc with a key opening which is so designed that the turning of the key does not directly act mechanically on the locking disc. The lock also includes a coupling element for coupling the locking disc to the turning movement of the key. The lock is provided with electric operator which is activated by means of the electronic code from the key and which in an active state controls the coupling element so that the locking disc turns with the key to a position required for opening of the locking mechanism.
