Title: Method and apparatus for heating bottle caps
Inventor: CASSELMAN DAVID S
IPC: F26B9/10
Filed: 1996-12-18
Abstract: A method and apparatus for heating a plurality of bottle caps simultaneously. The apparatus comprises a housing with an air blower, resistance heaters and a thermocouple positioned within its interior. Air blown through the interior is heated by resistance heaters and travels through air ducts positioned at the opposite end of the housing. The air duct is positioned in spaced relation to the interior of a hopper and has a series of apertures through which heated air is injected into the hopper's interior. The flow rate of the air is sufficiently high so that the heated air agitates the caps within the hopper and is evenly distributed throughout the interior of the hopper. The temperature of the air is controlled so that the caps are warmed to a temperature within the range of 88°F to 92°F.

Patent CA-2207488-A1 (CA)
Inventor: WATERHOUSE PAUL
IPC: G01N27/447
Filed: 1995-12-12
Abstract: L'invention concerne un moyen de détection amélioré et un appareil amélioré qui peut être utilisé individellement ou dans différentes combinaisons pour augmenter la capacité de l'appareil d'électrophorèse à détecter en un temps court des produits marqués par un fluorophore. Un tel appareil comprend un logement adapté pour recevoir un support de gel d'électrophorèse, une source d'excitation de radiations électromagnétiques ayant une fréquence appropriée pour induire l'émission de radiations électromagnétiques par le fluorophore; une pluralité de fibres optiques pour fournir des radiations électromagnétiques depuis la source d'excitation à un ensemble linéaire de sites d'excitation/détection sur le support de gel, des moyens de commutation optiques pour diriger successivement les radiations électromagnétiques vers un d'entre plusieurs groupes prédéfinis de fibres optiques; un moyen de détection tel qu'un tube photomultiplicateur ou un ensemble de tubes photomultiplicateurs pour détecter l'émission du fluorophore induite par une radiation d'une source d'excitation; et un moyen permettant de corréler une émission détectée avec la commutation d'une radiation électromagnétique d'excitation pour qu'une émission donnée puisse être liée au site irradié d'excitation/de détection. Par exemple, le moyen de commutation optique peut commuter entre une position où il dirige les radiations de la source vers chaque seconde fibre optique et une position où il peut alimenter en radiation successivement chaque troisième ou quatrième fibre. Egalement, on peut utiliser un réseau de formation d'un ensemble de points en divisant un faisceau incident de radiations cohérentes en un ensemble de petits faisceaux d'excitation et en dirigeant chaque petit faisceau d'excitation vers un site d'excitation/détection sur le gel d'électrophorèse. La diode émettrice de lumière prévue pour fournir l'énergie d'excitation à un ensemble de sites d'excitation/de détection peut également être utilisée. Cette dernière forme de l'appareil est particulièrement avantageuse à cause du prix bas des diodes émettrices de lumière (DEL) comparées aux sources cohérentes de lumière (c'est-à-dire lasers).

Inventor: STAMATELAKIS DEMETRIOS
IPC: H04L69/14
Filed: 1997-07-11
Abstract: A method for restoring traffic in a network. The network includes plural distinct nodes interconnected by plural distinct spans, each span having working links and spare links. Each node has a digital cross-connect switch for making and breaking connections between adjacent spans forming span pairs at a node. Cross-connections between spare links in adjacent spans are made such that sets of successive nodes through which the adjacent spans form span paths  form  closed  paths.  A  method  of  finding  and construction closed paths is described in which statelets are broadcast through the network. In a preferred method of implementation of the method, the statelet broadcast occurs not in response to a network failure, but across the entire network before any particular span failure and may be carried out during normal network operations as a continual re-configuration of the network.

Abstract: A filter and hydraulic mixing assembly for a water treatment system. The assembly includes two circulation tubes disposed alongside a center tube. During a backwash cycle fluid is conveyed through the center tube to a housing member where it is discharged immediately below the open bottom ends of the two circulation tubes thereby conveying media from the surrounding tank upwards through the circulation tubes. A cap member is fitted over the upper ends of the circulation tubes within the tank and direct the media being discharged from the circulation tubes into a downward spiraling helical flow pattern which provides enhanced agitation and lifting of the media bed. Discrete filter segments are selectively attachable to the housing member and interchanging the discrete filter segments permits the total filter slot area of the assembly to be adjusted and also permits the filter slot size to be altered. The filter segments are color coded, with each separate filter size having a different corresponding color. The color coding scheme provides an efficient and effectivemechanism for preventing the inadvertent mixing of filter segments having different slot sizes.
