Patent CA-2122401-A1 (CA)
Inventor: BOISJOLI STEPHANE
IPC: G01G5/06
Filed: 1994-04-28
Abstract: Un pont roulant servant aussi de pesée possède normalement à l'intérieur du système de soutènement une cellule de charge permettant de connaître la charge que soutient le crochet. La méthode traditionnelle pour calibrer la cellule de charge est de soulever des pièces de fonte dont la masse est précédemment connue. Le nouvel appareil permet de calibrer la cellule de charge du pont roulant sans l'ajout de charges extérieures. L'apport d'un cylindre hydraulique, dans le boîtier de soutènement relié au crochet et la force résultant de la pression hydraulique d'amarrage, jumelée à un système de lecture, permet la calibration de la cellule de charge. Le cylindre hydraulique est installé entre une plaque d'armature qui est considérée comme une partie fixe relativement à la cellule de charge et une plaque d'épaulement qui est une partie mobile destinée à faire déplacer la cellule de charge: l'application de la pression pousse la tête du cylindre contre la cellule de charge et simule l'action d'une pesée externe.

IPC: A63B63/00
Filed: 1994-05-06
Abstract: For aquatic recreational devices, it is convention to have a lightweight, buoyant target float  on the water's surface through which a  bail can be thrown.   In  this invention,  the swimming pool's diving board  or ladder  is used to  provide a  stationary base  from which a hoop and backboard is extended. Truss elements (pipe lengths) are easily varied to accommodate various board and ladder sizes and shapes.  The entire assembly can be installed or removed in moments due to its removable position locking piece(s) (different   piece(s)   for   the   ladder   and   diving   board arrangements).  This   configuration   provides   a   rugged. lightweight,  weather  resistant,  pool-safe  (no  sharp  edges), stationary target (for balls)  with backboard; ideally suited for competitive "pool basketball" matches.

Title: Apparatus for dissipating wave energy
Inventor: DORRELL DONALD E
IPC: E02B3/04
Filed: 1993-02-24
Abstract: A structure for dissipating the energy of waves impinging on a shore is disclosed which comprises one or more rows of mo-dules (10) positioned adjacent the shore. Each module incorporates a number of vanes (49, 49', 49", 126). The vanes are shaped and spaced so that a number of venturi passages (94) are defined between the vanes. Each vane has a frontal portion (49, 68', 68") which faces away from the shore, and is inclined from the vertical so that it slopes away from the shore to define an entrapment chamber (96, 96', 96") which forces an oncoming wave to pass through the venturi passages rather than over the module or be ref-lected. The sides (80) of the passages converge from front to back. A  longitudinally extending hub (50) causes the passages to converge also in the vertical direction. Each vane may be X-shaped and substantially symmetrical about a vertical plane through its centre. The modules are cast from a cementitious material and may incorporate a number of the vanes joined together at the hub which is located at the centre of the X. The vanes may be joined together at their upper and lower ends by cross members (28, 30, 32, 34, 128, 130, 156, 158). The passages may incorporate cross vanes (106) which divide the passage into sub-passages. Other vane shapes are disclosed. The vanes may be individually fabricated.

Title: Increased output on full arc admission impulse turbines
Inventor: SILVESTRI GEORGE J JR
IPC: F01D17/18
Filed: 1994-12-19
Abstract: A  method  and  apparatus  for  improving  steam turbine  heat  rate  in  a multiple  stage  steam  turbine increases the pressure drop across each stage and increases final  feedwater temperature.   The method reduces  the volumetric flow through each of the stages of the turbine by first determining the optimum pressure drop across a first stage of the turbine, then adjusting the reduced volumetric flow of each succeeding stage to distribute the resultant pressure increase across the multiple stages so as to establish the first stage pressure at about the determined optimum pressure.  In one form, the method is implemented by blocking steam flow through at least some spaces between nozzle blades in each stage.  The blocked spaces are distributed to avoid impulse excitation of vibration on the rotating blades of each stage.

Abstract: A memory management method for a microkernel architecture and the microkernel itself feature template regions which are defined by the microkernel in the memory, as special objects.  In the memory management method, after the microkernel is loaded into the memory of a data processing system, it begins creating task containers in the memory.  It does this by forming template regions as special objects in the memory,  the template regions having a set of attributes.  Then, when the microkernel forms a task in the memory, it does so by mapping the template region into the task.   The microkernel defines a virtual address space for the task based upon the template region.  Later, when the microkernel conducts virtual memory operations on the template regions,  the effect of the virtual memory operations is manifested in the task by means of the mapping relationship.  In this manner, a single template region can be mapped into multiple tasks,  simultaneously.   By directing virtual memory operations to the template region on which they will take effect, the sharing of the virtual memory operations is much easier to accomplish since the changes are made to a template region, not to the mapping of the template region within each task.

Abstract: [Abstract]          [Object]    In a pipetting apparatus for pipetting a sample with a nozzle,  imperfect nozzle clotting condition can be detected in addition to perfect nozzle clotting condition.          [Structure]    The pressure in the air hose 12 connected to the nozzle 10 for aspirating a sample 18 is detected by the pressure sensor 20, and the detected pressure value is transmitted to the clot detecting section 26.   In this clot detecting section 26, a plurality of pressure calculation periods are set to calculate the pressure difference in each of the calculation periods.          When at least one of the calculated pressure differences exceeds at least one of the predetermined threshold values corresponding to the calculation periods respectively,  a clot alarm is generated.  Since a plurality of the pressure calculation periods are set,  an imperfect clotting condition can be detected in addition to the perfect clotting condition,  thus improving pipetting accuracy.
