Abstract: A portable testing device for examining biological samples in one embodiment comprises a support and a tubular member having a lens holder adjacent one end thereof rotatably mounted on the support. A light source is moveable axially within the tubular member between an on position where the light source is illuminated and an off position. A biological sample support surface is provided adjacent the lens holder on which a biological sample to be examined is placed. A lens through which a user can look to examine a biological sample placed on the biological sample support surface is removably supported by the lens holder.  The light source and tubular member carry co-operating formations which are configured such that the light source moves axially within the tubular member upon rotation of the tubular member. In another embodiment the light source is stationary and is responsive to a light-sensitive circuit.

Title: Dispositif de fixation pour catheter
Inventor: BIERMAN STEVEN F
IPC: A61M25/02
Filed: 1996-08-07
Granted: 2009-01-20
Abstract: L'invention porte sur un système de fixation qui comprend un dispositif semblable à une suture, à structure simple, par lequel un tube à liquides ou un article médical similaire est facilement attaché à un patient sans utilisation d'aiguilles et sans suture. Le dispositif de fixation comprend de préférence deux fils ou filaments ainsi que deux réceptacles correspondants. Les filaments comprennent des protubérances qui agissent en interaction avec les ouvertures des réceptacles pour favoriser une insertion rapide des extrémités distales des filaments dans les réceptacles, mais empêchent la rétraction hors des réceptacles des extrémités distales des filaments. Un soignant enroule simplement le filament autour du tube à liquides ou fait passer le filament à travers un trou de suture dans l'article médical, puis fait passer l'extrémité distale du filament à travers l'ouverture du réceptacle de manière à ce que le filament maintienne fermement l'article médical contre la fixation du dispositif de fixation. La fixation elle-même comprend une surface inférieure adhésive qui peut être attachée sur la peau du patient.
Patent CA-2233376-C (CA)
Inventor: ATWOOD DAVID ALLAN
IPC: C01F7/304
Filed: 1998-03-30
Granted: 2001-05-22
Abstract: The invention is directed to making inorganic materials consisting of a metal and a group 16 element in the stoichiometric ratio of 2:3 from single source precursors having the same 2:3 metal to heteroatom stoichiometric ratio.     In particular, the invention discloses a process for making aluminum oxide from single source precursors that have an aluminum to oxygen ratio of 2:3.  The precursors are organoaluminum tetrametallic compounds containing organooxy bridging groups and organo terminal groups.  As these compounds tend to be viscous liquids or oils, they can be applied to a substrate surface then pyrolyzed to eliminate the organic ligands and produce aluminum oxide in situ, without using gas phase deposition techniques.

Title: Process for testing the operation of fittings
Inventor: KRADEPOHL PAUL
IPC: G01M13/003
Filed: 1996-11-13
Granted: 2005-11-15
Abstract: The invention relates to a method for checking the operational readiness of a fitting, at least one measure value being determined for a fitting-specific parameter and being compared with a previously fixed value. It is provided that the measured value is determined in the cold and unpressurized state of the fitting and is compared with a value, determined analytically from a function model of the fitting, for the fitting-specific parameter. There are fixed for this analytically determined value an upper and a lower limiting value which are assigned to states of the fitting which are still tolerable (design reserve). It is shown that the fitting is operationally ready when the measure value is between the upper and the lower limiting value.

Abstract: A multilayer plastic container having enhanced strength for high temperature and pressure applications such as the pasteurization of carbonated juice drinks. The container is commercially cost-effective in comparison to prior art pasteurizable glass containers, and provides all of the advantages of plastic over glass, i.e., lightweight, shatter-resistant, etc. In a particular embodiment, the multilayer container includes inner and outer layers of a relatively high IV virgin PET, e.g., 0.85-0.90 dl/g, and a core layer of post-consumer PET having a substantially lower IV. The container has a relatively tall and slender profile, with high orientation levels in the panel and shoulder, and an oriented thick-walled base with feet.  The base preferably has a high profile and angled foot pads which are allowed to move outwardly under creep. According to a method of making a multilayer preform for such container, an enhanced injection rate and mold pressure are utilized to enhance interlayer bonding and prevent separation of the layers in spite of their substantial differences in IV.

Abstract: A combustion burner includes a housing (220) secured to the top of a water heater (10), a gas tube (230) in fluid communication with a source of gas and depending vertically from the housing (220) and positioned within a heat exchange tube (120) of the water heater (10). The ignition assembly (245) depends vertically from the top of the housing through the gas tube (230) and into the heat exchange tube. An angled nozzle (250), extending from the housing, transports air from an air blower (14) through the housing and into an annulus (254) defined between the exterior of the annular chamber and the interior of the heat exchange tube. A deflector plate (270) having a first and second series of slots (274, 280) enables the production of a long narrow flame within the heat exchange tube. A removable air restrictor plate (260) positioned within the angled nozzle accelerates the air through the housing, thereby enabling the burner to achieve different thermal ratings without altering the air blower output.

Abstract: A hybrid central office for serving a plurality of subscriber lines while serving as a virtual access tandem to a subnetwork of central offices having a connection to an ATM backbone network is described. The hybrid central office includes a computing module having a messaging interface to the ATM network, an inter--working trunk interface to the ATM network and a trunk connection to the PSTN. The hybrid central office serves as a tandem switch for other central offices connected to the subnetwork. Other central offices are preferably connected to the subnetwork by a signal large trunk group. A11 inter-office call routing is therefore handled by the hybrid central office. The hybrid central office also provides a gateway to the PSTN. Inter-office calls originated and terminated within the subnetwork are set up by the virtual access tandem but after call set up, the virtual access tandem is not involved in the call. The advantage is the utilization of spare processing capacity in a central office to off-load inter-office trunking congestion, as well as a significant reduction in trunking maintenance costs.
