Patent CA-2263396-A1 (CA)
Title: Off-the-road tire temperature and pressure monitoring system
Inventor: PROW ROBERT
IPC: B60C23/00
Filed: 1999-02-25
Abstract: A tire pressure and temperature measurement system adapts a Y-block (30) to an existing valve stem (20). One branch (44) of the Y-block accepts a conventional valve core (42) and another branch (38) accepts a flexible tubular temperature sensor (36) that leads "down the throat" of the existing valve stem and into the interior of a tire (14, 18). Another embodiment is adapted for use on inside dual tires (18). Making a measurement entails attaching a pressure sensor (40) to the valve stem and attaching a hand-held processor (112) to the sensors. The hand-held processor reads the current tire pressure and temperature; executes a program (Eqs. 1-6) that accounts for measured and target temperatures, vapor pressures, and gas compressibility; and indicates how much pressure to add or subtract to the tire to achieve an accurate final tire.operating pressure. In yet another embodiment, a spherical protective housing (70) enclosing pressure and temperature sensors (72), a controller 76, and a data transceiver (74) is loosely placed within the interior of a tire when it is mounted to a rim. A remote measurement system (80) receives at another data transceiver (108) pressure and temperature data transmitted from inside the tire while the vehicle is moving and conveys the data to a processor (112) for executing the above-described program.

Title: Fault indicator having remote light indication of fault detection
Inventor: FEIGHT LAURENCE V
IPC: G01R19/165
Filed: 1999-05-12
Abstract: A fault indicator contained within a protective equipment closure of the type used to house pad-mounted components of a power distribution system detects the occurrence of a fault current in a monitored conductor and provides a light indication thereof. The fault indicator includes a circuit monitoring module, having an integral fault indicator flag module, and a remote fault indicator light module. A status-indicating flag is rotatably mounted in the integral fault indicator flag module. The flag is positioned in either a reset indicating position or a fault indicating position by a magnetic pole piece, which is magnetized in one magnetic direction or the other by momentary application of a current in one direction or the other to an actuator winding on the pole piece. A magnetically actuated reed switch in an auxiliary magnetic circuit comprising an auxiliary pole piece magnetized by the actuator winding and a bias magnet magnetically aligned to oppose the reset magnetic orientation and reenforce the trip magnetic orientation of the magnetic pole piece closes upon occurrence of the fault current to connect an internal battery to an LED contained within the remote fault indicator light module so that the LED is visible from the exterior of the protective equipment enclosure. The sufficiency of the energy level of the battery may be tested by actuating a magnetically actuated reed switch contained within the remote fault indicator light module, which likewise connects the battery to the LED.

Title: Method and arrangement for measuring the content of chemicals during bleaching
Inventor: NORDER STIG
IPC: G01N33/15
Filed: 1997-12-23
Abstract: The invention relates to a method and a device for measuring the content of chemicals used in connection with bleaching of preferably cellulose fibres in a pulp suspension for the purpose of providing a better and more uniform product quality and preventing overdosage of the bleaching chemical used. According to the invention a measurement sample is derived from a predetermined volume of the pulp suspension after or during the bleaching. Further, a catalyst in the shape of the enzyme catalase is added to the sample , which is agitated so that the bleaching chemical is decomposed and oxygen gas is generated, which oxygen gas pushes out a certain sample volume for the measurement sample, which sample volume is directly or indirectly converted, e.g. via a simple algorithm, to a value representing the content of the bleaching chemical used.
Patent CA-2276967-A1 (CA)
Inventor: TANIGAWA HIDEMI
IPC: F02P15/00
Filed: 1999-07-07
Abstract: An electrical cable for high-voltage circuits is used in fixed type apparatuses such as office or home appliances. The cable comprises a reinforcing thread, which is baked with a fluorocarbon rubber paint, to form a small-diameter cable core portion. The cable core portion is wound with a conductive wire having a wire core portion and a semi electroconductive wire-coating. As the conductive wire includes the semi-electroconductive coating, it can be wound densely. As a result, the electrical cable as a whole can be made thinner, while maintaining a high noise-suppressing effect.

Patent CA-2285096-A1 (CA)
Inventor: KOLLAR LUBOR
IPC: G06F12/109
Filed: 1991-11-12
Abstract: Method and means are provided for simulating a contiguous data space within a computer memory, and for placing and accessing data objects of various sizes within the simulated contiguous data space. Multiple, sub-data spaces are concatenated in such a way that each page and each sub-data space in the contiguous data space are uniquely identified.  Data objects are placed in the contiguous data space and at the first reference to a page of the data object, only the segment containing the referenced page in the contiguous data space is mapped to the database storage disk. Once a data space page is mapped, the operating system can read the page into memory without requesting a disk operation from the database manager. On modifying a page, if the database disk page location is changed, the contiguous data space page is re-mapped without changing the page address in the data space. Also, modified data pages are re-written to the database storage disk in an ongoing manner set by the user, instead of at intervals set by the operating system.
