Patent CA-2050474-A1 (CA)
Title: Device and method for ventilation
Inventor: AALTO ERKKI
IPC: F24F7/08
Filed: 1991-01-30
Abstract: ABSTRACT OF THE DISCLOSURE          The invention concerns a ventilation device, through which impure air is removed out of a room, in particular out of the proximity of a source of impurities at a working point in the room space.  According to the invention, through the device, besides the removal of impure air and/or excess heat from the source of impurities as a limited-area removal, air of general removal is also removed through the device, the suction opening for general removal being preferably opened into the same exhaust chamber into which the suction opening for the space for collecting of impurities in the interior of, for example, a kitchen hood is opened.  The device may also include a flow opening for the general intake.  Thus, the device can operate as a device for limited-area ventilation and for general ventilation serving for the whole room.

Abstract: Case 27160 ABSTRACT OF THE DISCLOSURE       A method of measuring the amount of cyclosporin in a sample suspected of containing cyclosporin is disclosed.  A method of inactivating interfering cross-reactive material in an assay for measuring the amount of cyclosporin in a sample suspected of containing cyclosporin is also disclosed.  Compositions wherein cyclosporin is conjugated to an immunogenic carrier or a label, optionally through a linking group, at an alanine nitrogen atom of the cyclic backbone of cyclosporin are also disclosed.  Compositions wherein atiocyclosporin is conjugated, optionally through a linking group, to an immunogenic carrier or a label are also disclosed.  Where cyclosporin is conjugated to an immunogenic carrier, the conjugates may be used as immunogens for the preparation of antibodies which are capable of recognizing cyclosporin.  Where atiocyclosporin is conjugated to an immunogenic carrier, the conjugates may be used as immunogens for the preparation of antibodies which are capable of recognizing interfering cross-reactive material but substantially incapable of recognizing cyclosporin or cyclosporin-label conjugates.  Where cyclosporin is conjugated to a label, the conjugates may be used as part of a signal producing system in cyclosporin assays.  Both the antibodies and label conjugates are useful in the disclosed assay methods.

Title: System for squelching communications circuits terminating in failed ring nodes
Inventor: KREMER WILHELM
IPC: H04Q11/04
Filed: 1992-04-07
Abstract: Misconnections between communications circuits in a bidirectional line-switched ring transmission system are eliminated by deterministically squelching in adjacent ring nodes, i.e., loop-back-switching nodes, communications circuits terminated in failed ring nodes in the ring transmission system. The deterministic squelching is realized by provisioning the ring nodes with all active communications circuits including those passing through the node which are terminated in other ring nodes in the bidirectional line-switched ring transmission system. Then, when one or more adjacent ring nodes fail, all active communications circuits terminated in those failed ring nodes are squelched in the adjacent ring nodes, i.e., in the loop-back-switching ring nodes.

Title: Variable length pipe connector and method of manufacture and use
Inventor: WITTER MELVIN L
IPC: F16L27/12
Filed: 1990-09-27
Abstract: A pipe connector (10) which may be varied in length and a method for installing the connector is disclosed. Also disclosed is a tool (64, 65) for aiding in the fabrication of the female portion of the connector. The connector consists of telescoping male and female pipes (14 and 12) which are joined by the action of a wire spring (28) positioned in recesses (22 and 54) in the two pipes.  The recesses are designed to allow only one-way movement between the telescoping pipes until such time as a release groove (56) is reached. The release groove (56) is formed in male pipes (14) beyond the normal operating range of the connector. When the wire spring (28) is positioned in the release groove (56), the pipes may be separated. The tool (64 and 66) described allows for on site fabrication of the recess (22) in female pipe (12).
