Title: Fibre optic transducer
Inventor: HAYWOOD JOHN
IPC: G01R15/24
Filed: 1996-05-30
Abstract: A fibre optic transducer, which may take the form of a current sensor, and which comprises a first light path which is defined by a light transmitting element (19) and a second light path which is defined by a coil (10) of optical fibre (11). The coil-forming optical fibre (11) has a length which is significantly greater than that of the light transmitting element (19). A  modulated light source (14) is provided for directing light simultaneously into both the first and the second light paths. Also, the transducer includes detector/processing circuitry (15 to 17 and 20 to 24) for detecting for light exiting from the light paths during successive time periods that include first and second time intervals t1 and t2. The detector/processing circuitry includes means for referencing the level of light that exits from the coil (10) with respect to that which exits from the light transmitting element (19) and, to this end, use is made of the difference in transmission time of light through the first and second light path having the significantly different lengths.

Title: Crimp joint connecting pipes
Inventor: STORGARD CHRISTER
IPC: F16L47/22
Filed: 1996-05-30
Abstract: The present invention relates to a method for making joints (10) between pipes. A first pipe part (1) to be connected is made of plastic material and it has an original inner diameter (D1), which is smaller than the outer diameter (D2) of a second pipe part (2) to be connected. The end section (11) of the first pipe part is expanded so that its inner diameter becomes larger than the outer diameter of the second pipe part; the first and second pipe parts can then be arranged one within the other, and the memory of the plastic material is allowed to reset the dimensions of the first pipe part, which then presses against the second pipe part forming a shrink joint (10) between the pipe parts (1, 2). Both end sections (11) of the first pipe part are expanded, and support pieces (3a, 3b) maintaining the expanded inner diameters are placed within the pipe parts. After the first pipe part has been transported to the site of operation, the support piece is removed, the first and second pipe parts are placed one within the other, and the memory of the plastic material is allowed to reset the expanded section of the first pipe part in order to provide a shrink joint between the pipe parts.

Title: Supply circuit for discharge lamps with overvoltage protection
Inventor: CANOVA ANTONIO
IPC: H05B41/285
Filed: 1998-04-20
Abstract: The supply circuit for discharge lamps (L) comprises an inverter (3) for generating a supply voltage at a specified switching frequency (f c) for a load circuit (15) comprising at least one lamp (L) and a resonant circuit (23, 25) in series with the electrodes (17, 19) of the said lamp.

Patent CA-2235526-A1 (CA)
Inventor: SUN HENGHU
IPC: C04B28/06
Filed: 1998-04-22
Abstract: This invention discloses a high pulp density, fast setting and high early strength backfill method for underground mining, in which novel binding materials, with high early strength properties, are used as the binding reagent, where mine tailings, natural sands, ground sands and industrial waste materials are used as aggregate. The binding material, aggregate and water are mixed together uniformly to produce a high pulp density backfill slurry with 65 - 85% pulp densities. The backfill slurry produced is transported to underground mining stopes through a pipeline by gravity or pumping. Once the backfill slurry fills the stope, it quickly solidifies within several hours into a solid backfill body with high early strength. One obvious advantage of the present invention, compared with the traditional backfill methods using Portland cement as binding material, is that one tonne of the novel material obtains the same compressive strength as threes tonnes of Portland cement as binding material. Another important property of the present backfill materials and methods is that the curing time for the backfill body will be decreased from 7 - 28 days to 1 - 3 days, which can significantly decrease the operation cycle time for underground mining and increase efficiency. Because of the very good early strength and homogeneous backfill body, better working conditions and improved safety in mining operations are achieved. Further, because of the large amount of mine tailing being used as aggregates without classification, the surface pollution in mines is decreased. The new methods disclosed in this invention may be combined with various mining methods to form upward backfill, downward backfill, partial backfill, complete backfill and other types of backfill, to be used in diverse mining conditions.

Inventor: JOHNSON GARY E
IPC: A63C10/24
Filed: 1997-01-16
Abstract: Attachment for a binding having straps and fitting a user's boot, the binding attached to a snow gliding or wake boarding device. Upon detachment of one end of each strap of the binding, the ends are attached to a spanning bar (11). A closing lever (10) is mounted to the spanning bar (12, 14) to provide a preselected mechanical advantage. A  front clip (30) having a niche rod (32) is mounted near the tow end of the binding (33), and a rear clip (20) having a latch (26) is mounted near the heel end. The closing lever is engaged with the niche rod (32) and then with the latch (26), moving the spanning bar downward and tightening the straps around the boot. The first insertion of the boot requires adjustment of the strap tension; subsequent insertions do not require further adjustment. The closing lever (10) is releasable from the latch, loosening the straps for boot removal. The latch may be fitted with a cable release and a safety lock (28) to prevent disengagement of the closing lever from the latch.

Abstract: A method and kit are provided for identifying and characterizing one of a cellular component or small molecule. The method and kit include a hybrid ligand molecule (7) formed from two ligands such that one of the ligands is the small molecule (7b) whose specificity is to be determined while the other ligand has a specificity for a predetermined target (7a). The hybrid ligand is introduced into an environment containing: a first expression vector encoding a target for one of the ligands linked to a coding sequence for a first transcriptional module (8); and a second expression vector including a target for the other ligand linked to a coding sequence for a second transcriptional module (9). The environment further contains a third vector (6) including a reporter gene where the expression of the reporter gene (5) is conditioned on the proximity of the first and second transcriptional modules which is facilitated by the binding of both ligands in the hybrid ligand molecule to their targets.

Title: Multi-mode communication network with handset-selected channel assignments
Inventor: ZICKER ROBERT G
IPC: H04M1/72511
Filed: 1997-06-03
Abstract: A multi-mode communication network (12) accommodates piloted cellular operation and pilotless cordless operation using a multi-mode handset (18). A  common pool of channels (28) serves cellular and cordless operations. At least some channels from a cordless subset (32) of the pool of channels (28) are unused in cellular operations regardless of location. The handset (18) monitors forward portions of all cordless subset channels when the handset (18) is within the coverage area (16) of its cordless base station (22). Unused channels are indicated on a dormant channel list (70), which is passed to the handset's cordless base station (22) when the handset (18) registers for cordless operation. The cordless base station (22) makes an active channel list (62) based upon the dormant channel list (70). Cordless operation messages transmitted from either a handset (18) or cordless base station (22) use a channel selected from the active channel list (62).
