Title: Grouting composition and method
Inventor: LIAO ANDREW W
IPC: C04B28/00
Filed: 1994-11-09
Abstract: A grouting composition comprised of (a) 84-95 % by weight of granular sodium-based bentonite, (b) 1-8 % by weight of finely divided salt-water hydratable sepiolite, and (c) 4.8 % by weight of a clay stabilizer. The grout composition which contains no organic polymeric substances is mixed with fresh water to provide a pumpable rebydratable, and easily applied grouting slurry. The slurry admixture will form a solid seal with low hydraulic conductivity and high structural stability. The grouting composition is useful for scaling the annular space around a well casing and plugging abandoned wells in practically all types of formations. A preferred grouting composition comprises 88-90 % by weight of granular sodium bentonite, 6-7 by weight of sepiolite, and 4-5 % by weight of granular ammonium sulfate. In use, 50 pounds of the preferred grouting composition is mixed with 13-14 gallons of fresh water directly to provide a grouting slurry with a total of 30-32 % by weight of active solids and a density of 10.1-10.3 pounds per gallon. The slurry admixture is a completely inorganic non-toxic, and environmentally safe grouting system.

Title: Environmentally-safe apparatus for disposing of light bulbs
Inventor: EMMERSON DANA
IPC: B01D53/02
Filed: 1996-06-03
Abstract: A portable unitary apparatus is provided herein for disposing of light bulbs, e.g., fluorescent bulbs. The apparatus includes an open-topped, multi-compartmented container of circular cylindrical cross-section. The container includes an upper operating compartment, an intermediate collection compartment, and a lower exhaust compartment having an axial inlet and a radial outlet port. A lid is hingedly-connected to, and is adapted to cover, the top of the container. The lower surface of the lid is connected to a reduction chamber, which is disposed within the upper operating compartment. The reduction chamber has an axial inlet means for a bulb to be pulverized and an axial outlet means leading to the collection chamber. An electric motor provided with an on/off switch is disposed in the upper operating compartment by being secured to the reduction chamber, and has a drive shaft extending into the reduction chamber. A rigid unitary pulverizing blade is secured to the drive shaft. A light bulb feed chute extends through the lid and is attached thereto. The chute has an inlet opening which is disposed above the upper surface of the lid and an outlet opening which is disposed within the reduction chamber. A disposable pulverized light bulb collection bag is selectively-disposed within the collection chamber in air-sealed relationship to the axial outlet means of the reduction chamber. A vacuum motor is operatively-disposed within the lower exhaust chamber. It has an axial inlet at sub-atmospheric pressure connected to an axial outlet from the intermediate collection compartment to draw gases and particulates from the collection compartment into the lower exhaust compartment. The vacuum motor expels gases into the exhaust compartment at an overpressure.
Patent CA-2181056-A1 (CA)
Inventor: O'CONNOR LAWRENCE J
IPC: C09J7/22
Filed: 1995-01-23
Abstract: Ruban étroit de forte résistance et de faible allongement à la rupture utilisable par exemple en tant que bandelette d'ouverture ou ruban d'emballage, formé par extrusion continue d'une bande, de préférence en polypropylène, et par application d'une couche adhésive sur une surface de ladite bande. Après extrusion et après application de la bande adhésive, on étire le ruban longitudinalement sur une longueur suffisante pour orienter pleinement le ruban dans la direction longitudinale afin d'obtenir le faible allongement à la rupture et la haute résistance. Ladite bande est extrudée en une largeur telle qu'après étirement, la largeur du ruban étiré est égale à la largeur requise du ruban fini. Au lieu de refendre le ruban en sens machine à partir d'une bande large, le ruban est extrudé directement en ruban sans refente ou rognage, ce qui évite ainsi tout déchet. De plus, l'étirement longitudinal du ruban réduit l'épaisseur de l'adhésif à une épaisseur juste suffisante pour obtenir le niveau requis d'adhésion autocollante sans qu'il soit nécessaire d'utiliser des matières supplémentaires.

Title: System for transmitting paging signals using time-division multiplexing
Inventor: GODOROJA ANDREI
IPC: H04L12/56
Filed: 1995-03-03
Abstract: A time-division multiplexed paging system for transmitting multiple paging messages on the same frequency. A geographic area is divided into a plurality of cells (30-50) having base stations that transmit radio frequency signals in the cells. Each base station is assigned a time slot (A, B or C) at which paging messages may be transmitted. The assignment is made such that no base stations having overlapping radio frequency coverage areas transmit during the same time. A locate signal is simultaneously broadcast throughout a geographic area in order to locate a paging unit (P1). Upon receipt of the locate signal, the paging unit (P1) transmits an acknowledge signal back to the paging system. The cell (30) in which the paging unit (P1) is located is determined based upon the signal strength of the received acknowledged signal. A paging message is transmitted from the base station in the cell (30) in which the paging unit (P1) is located during the time slot (A) that is assigned to the base station.

Patent CA-2205678-A1 (CA)
Title: Gas storage method and product
Inventor: PERRY GLEN
IPC: C10L3/00
Filed: 1997-05-16
Abstract: For storage of natural gas at pressures over 1,000 psia, it is advantageous to add to natural gas an additive which is a C2 or C3 hydrocarbon compound, or a mixture of such hydrocarbon compounds. Above a lower limit (which varies with the additive being added and the pressure), a decrease in the amount of power needed to compress the mixture. For storage or pipeline transportation of natural gas at pressures over 800 psia, it is advantageous to add ammonia to the natural gas, in an amount such that the ammonia does not create a liquid phase at the temperature and pressure used. The ammonia-natural gas mixture can be compressed or pumped with a lower energy expenditure than would be needed for an equivalent volume of natural gas alone. When more than 4% by volume of ammonia is present, the pumping through pipelines is also aided by the refrigerant effect of the ammonia, which reduces the temperature of the gas being transported.   Instead of ammonia, hydrogen fluoride or carbon monoxide can be added to the natural gas, but these are less preferred than ammonia.

Title: Viscous heater
Inventor: MORI HIDEFUMI
IPC: F24J3/00
Filed: 1997-07-14
Abstract: A viscous heater is provided with a front side plate 2 and a rear side plate 3, which are arranged so that a heat generating chamber 5 is formed between their facing back surfaces and which are stored in a housing so that heat emission chambers FW and RW are formed between the side plates and the housing.  The housing is formed by a front housing having a tubular part 1c which extends axially for storing the front and side plates radially inwardly of the tubular part 1c and a rear housing 4. Thus, sealing is necessary only at a location where the front and rear housings 1 and 4 are connected with each other.  Thus, a very simple structure is sufficient for preventing any leakage of the recirculated fluid.
