Title: Fuse cutout assembly and method
Inventor: DAVIS KENNETH S
IPC: H01H85/42
Filed: 1994-04-14
Abstract: A fuse cutout assembly (21) including a containment housing (22), a fuse (23), amounting assembly (24) mounting the fuse (23) in the housing (22) for electrical connection to an electrical circuit.  A plunger assembly (29) is movably mounted at least partially inside the housing (22) and preferably surrounding the fuse (23).  An electrical conductor (28) is electrically connected to the fuse (23) and mechanically connected to the plunger assembly (29).  The plunger assembly (29) is supported in the housing (22) in a first position and is formed to be propelled inside the housing (22) away from the first position to a second position by the hot gases generated upon rapid melting of the fuse (23). Movement of the plunger assembly (29) is preferably yieldably resisted by the air trapped between the plunger assembly (29) and the housing (22), which may be vented during plunger movement.  Additional venting (94) for excessive pressure buildup can be provided in the housing (22), and a method of containing the hot gases and metals generated during fuse melting and retaining the components  of the cutout assembly (21) is also provided.

Patent CA-2166279-A1 (CA)
Inventor: TRAMPLER FELIX
IPC: B01D21/00
Filed: 1994-07-04
Abstract: On peut séparer et recycler au moyen d'une onde de résonance ultrasonore des particules en suspension dans un fluide. Dans une variante préférée, le champ de résonance ultrasonore émane d'un résonateur composite multicouche qui comporte un transducteur, la suspension et un miroir placés en parallèle. On choisit des dimensions et fréquences faisant entrer l'ensemble du système en résonance mais pas des fréquences propres susceptibles d'exciter le transducteur et le miroir eux-mêmes, de façon à minimiser la dissipation thermique. On définit des critères de direction et de débit de flux permettant de maintenir un facteur de haute qualité du résonateur composite et de parvenir à une séparation poussée. Un tel procédé convient en général à tous les types de particules (dispersées en phase solide, liquide ou gazeuse), notamment pour des hydrosols (particules contenues dans de l'eau) et pour séparer des particules biologiques telles que des cellules ou agrégats provenant de mammifères, de bactéries ou de plantes. On décrit des applications spécialisées en biotechnologie où intervient un filtre acoustique destiné à des bioréacteurs pour cellules de mammifères ou à la rétention sélective de cellules viables par opposition aux non viables.

Title: Three-dimensional phenotypic measuring system for animals
Inventor: ELLIS JAMES S
IPC: G06V10/145
Filed: 1995-04-10
Abstract: A system (132, 136) measures the three-dimensional phenotypic characteristics of an animal (108), such as a dairy cow. The system uses a large number of modulated laser light beams (111) from a laser camera (132) to measure approximately 100 points per square inch of the animal. Each laser beam measures intensity, horizontal, vertical, and depth dimensions, and by combining the measurements, the system composes a very accurate three-dimensional image of the animal. The system (132, 136) calculates the desired phenotypic measurements for conformation of the animal by combining measurements of selected points on the animal. The system then stores the measurements for each animal in a computer data base (412) for later use. The system also stores a light intensity image of the animal's markings which is compared to other stored images.

Patent CA-2189369-A1 (CA)
Title: Hydrocarbon bailer
Inventor: DIADELFO ANGELO
IPC: G01N1/10
Filed: 1996-11-01
Abstract: The hydrocarbon bailer is used for the removal or sampling of light non aqueous phase liquids present in groundwater or waste water. Its simple design consists of a hollow tube with a hook, polypropylene ball and a ball check. The polypropylene ball is the driving mechanism of the design, since it has the capability to float on water, yet sink in a wide range of hydrocarbons. The ball seat is a flush "V" threaded ball check screwed onto the bottom of the bailer, designed so that the ball may sit comfortably on it. The ball check is also designed with an O-ring, which is necessary for leak prevention. The hydrocarbon bailer is equipped with a hook, enabling the attachment of a rope at the top of the bailer, so that it may be descended to any required or specified length. When the bailer is inserted into the ground water or waste water, both water and hydrocarbon will enter the hydrocarbon bailer. Naturally, the oil will float on top, the water will sink to the bottom, and the ball will float on the interface between the oil and the water. As the bailer will be lifted, the water will drain. The ball will follow until it sits comfortably on the ball seat. As a result, the position of the ball will prevent oil from leaking out of the tube. Essentially, a water-free oil sample will be obtained.
