Abstract: A flexible strip test cable having an elongated flexible strip cable, a series of strip traces disposed lengthwise on the flexible strip cable and having electrical strip contacts near one end of the flexible strip cable, an extension cable integral with the flexible strip cable and having a width at one end greater than the width of the flexible strip cable, and a series of test traces on the extension cable having electrical test contacts near the end of the extension cable remote from the flexible strip cable. Each of the test traces is electrically connected to one of the strip traces, and the minimum distance between two test contacts is greater than the minimum distance between two strip contacts. The flexible strip test cable may have a tooling guide for aligning a cutting tool with the end of the flexible strip cable which is connected to the extension cable. Alternatively, the test contacts may be electrically accessible through one surface of the extension cable in any pattern so that the minimum distance between two test contacts is greater than the minimum distance between two strip contacts. In still another embodiment, at least one test contact is electrically accessible through one surface of the extension cable and at least one test contact is electrically accessible through the opposing surface of the extension cable.

Abstract: A system for electronically controlling brakes on a train is disclosed.  The system is responsive to a brake handle positionable into any one of a plurality of discrete positions.  The discrete brake control system includes a cab station unit, a brake control unit, a comm channel and a direct communication device.  The cab station unit generates both a base signal stream and a dedicated signal stream.  The base signal stream is indicative of parameters for operating the  system including the discrete brake  handle positions.  The dedicated signal stream is solely indicative of the discrete brake handle positions.  The brake control unit controls operation of the brakes in coordinated response to both the base and the dedicated signal streams.  The comm channel is the route through which the base signal stream is communicated from the cab station unit to the brake control unit.  The direct communication device is in parallel with the comm channel and is the route through which the dedicated signal stream is communicated from the cab station unit to the brake control unit.  Information pertaining to the discrete brake handle positions is communicated to the brake control unit faster through the direct communication device than through the comm channel.  This enables the brake control unit to respond promptly to positioning of the brake handle.

Title: Leakage detection
Inventor: BOWLING MICHAEL
IPC: F28D7/00
Filed: 1994-12-14
Abstract: A vessel such as a dairy pasteuriser having a path (B) for product and a separate path (A) for coolant in intimate relationship is tested for leaks by circulating a donor fluid under pressure in path (A) whilst a recipient fluid such as clean tap water is circulated in path (B). If the donor fluid is an electrolyte, a probe is placed in path (B) to measure the conductivity of the recipient fluid. A rise in conductivity over a period indicates leakage between the two paths, the rate of change indicating the size of the leak. Alternatively, the donor fluid can be a gas, and leakage detected using an ultrasound probe.
Patent CA-2182281-A1 (CA)
Inventor: SPRING THOMAS G
IPC: G01N27/06
Filed: 1995-02-06
Abstract: The present invention provides an immobilization medium which can immobilize bioreagents to support materials and which dries to a water resistant layer or film. The immobilization medium comprises (i) a liquid or fluid binding reagent and (ii) complexes of a biore-agent immobilized to a solid phase which are evenly dispensed within the binding reagent. The suspension can further include supplemental ingredients evenly dis-persed throughout the medium which can provide the medium with electrochemical properties, enhance the stability of the immobilized bioreagent and/or improve the medium's capability of drying to a substantially water resistant or insoluble layer. The immobilization medium provided by the instant invention is in the form of a homogeneous liquid suspension. The immobiliz-ing medium of the present invention can be employed in essentially any assay format which utilizes an immobi-lized bioreagent. For example, using the immobilization medium, an enzyme electrode can be manufactured and used in conjunction with a counter and reference elec-trode to electrochemically detect the bioconversion of the enzyme's substrate, a biosensor can be manufactured which is capable, via non-electrochemical means, of de-tecting the bioconversion of the enzyme's substrate; and a solid phase can be manufactured which can be used in heterogeneous immunoassay formats known in the art.

Title: Method and device for manufacturing biaxially oriented tubing from thermoplastic material
Inventor: PRENGER JAN HENDRIK
IPC: B29C48/90
Filed: 1995-05-03
Abstract: A tube is extruded from a thermoplastic material and is then forced over a mandrel at an orientation temperature of the material. The mandrel has an expanding section that expands the tube in its circumferential direction. A tube speed controller upstream of the expanding section of the mandrel exerts an axial force on the tube, and a puller downstream of the mandrel exerts an axial pulling force on the tube. Upstream of the tube speed controller, an outer layer of a wall of the tube is brought to a temperature below the orientation temperature. That outer layer is thick enough to withstand the force exerted by the tube speed controller.

Abstract: A non-aqueous cell comprising a rolled electrode assembly including a positive plate with an active layer, a negative plate with an active layer, and a separator between the active layers of the positive and the negative plates;  and a case that contains the electrode assembly and a non-aqueous electrolyte.  In this cell, a metallic portion disposed in association with the positive plate and having an equipotential to the positive plate is equipped on at least one of the sides thereof with a portion having no active layer, and thus forms a positive plate equipotential exposed metallic portion (.alpha.) extending in a lontitudinal direction for a length at least one turn, and this positive plate equipotential exposed metallic portion (.alpha.) is so arranged as to oppose a negative plate equipotential exposed metallic portion (.beta.) disposed in association with the negative plate, for a length at least one turn. The invention discloses also a non-aqueous cell produced by employing a simple laminate electrode assembly or a zigzag-woven laminate electrode assembly, which has substantially the same structure as the rolled electrode assembly. Due to the unique construction described above, even when the case is crushed by an external pressure or when overcharge is generated due to abnormality in a charger circuit, etc, or when a nail, etc, pierces the cell or when the cell is abnormally heated from outside, an abnormal rise of the cell temperature is limited due to internal short-circuit of the metals having sufficiently low resistance, and the safety of the cell is therefore ensured.
