Title: Hazardous waste disposal method and composition
Inventor: BABCOCK H NASH
IPC: B28B19/00
Filed: 1992-02-27
Granted: 1997-08-12
Abstract: A method of immobilizing a hazardous waste is provided. The method comprises providing a dry cementitious composition capable of hardening and in the form of finely divided particles of at least one cement binder, placing an amount of the dry cementitious composition into the hazardous waste with or without an additional added volume of water, without any type of physical mixing of the cementitious composition and water other than the mixing which occurs merely by applying the cementitious composition into the water. The major portion of the particles of the cementitious composition have approximately the same drop rate through the volume of water. The water contacts the dry cementitious composition when poured into the volume of water to hydrate the particles of the dry cementitious composition, the particles of cementitious composition dropping through the water to displace excess water and form the hydrated cementitious composition particles in a substantially non-segregated mass. The hydrated cementitious composition is then allowed to set and cure to a solid mass. The set time may vary from less than a few seconds to many hours and even days to immobilize the hazardous waste. The cementitious composition may have a neutralizer for the hazardous waste.

Title: Eddy current drive and motor control system for oil well pumping
Inventor: WOLCOTT JOHN H
IPC: F04B49/06
Filed: 1993-03-16
Granted: 1999-11-30
Abstract: An eddy current coupling with an electrically controllable field current is used to rotatably connect a drive motor to an oil well pumping mechanism where the eddy current drive speed is controlled to a reference speed using a speed feedback control system and operation can be limited in torque output by a torque feedback control system. in a first alternative embodiment, the eddy current coupling output speed is controlled by a stroke modulation unit using a first selected speed for the upward pumping stroke and a second selected speed for the downward pumping stroke. In a second alternative embodiment a controller is used to select torque or speed control for the upward or downward pumping stroke. An eddy current coupling output stall condition is sensed by comparing the eddy current drive speed to a preselected stall speed and when the eddy current coupling output speed dips below the stall speed limit, the eddy current coupling coil electrical power is disconnected thereby terminating the electromagnetic coupling of the eddy current inductor and pole member to disconnect the drive motor from the oil well pumping mechanism.

Title: Conductive face-cooled laser crystal
Inventor: MATTHEWS STEVEN C
IPC: H01S3/109
Filed: 1993-04-14
Granted: 1998-01-06
Abstract: A technique for passively removing heat from an optical element in a laser system through its optically transmissive faces. Heat is removed by way of optically transmissive heat sinks or other heat conducting media disposed adjacent the optically transmissive surfaces of the optical element. Heat is transferred out of the optical element in a direction parallel to the direction of propagation of energy, thus minimizing problems associated with thermal gradients. Devices employing optical elements such as nonlinear frequency conversion crystals and laser crystals may utilize the heat management approach of the present invention to achieve better performance. Heat is transferred to the heat conducting media by direct contact, or through narrow gas-filled gaps disposed between the optical element and the heat conducting media.

Title: Process for removal of suspended solids from pulp and paper mill effluents
Inventor: DORICA JOSEPH
IPC: C02F1/52
Filed: 1993-11-10
Granted: 2000-07-18
Abstract: A process is presented for removal of suspended solids including resin and fatty acids from pulp mill effluents including Chemi-Thermo-Mechanical Pulp (CTMP) mill and deinking effluents. The process involves filtration of untreated or primary treated effluents through a mat of primary sludge, pulp or woodroom sludge. A sludge mat is formed on a belt or drum filter wire screen or punched drum and the effluent to be treated is filtered through the mat.      Most of the suspended solids and a part of colloidal material and dissolved solids are retained by the mat.      Following the filtration stage, the sludge is dewatered and removed. A portion of the sludge is recycled to form the mat for the next filtration cycle, while the excess sludge is purged. The filtration is achieved by the application of vacuum below the filter mat ar pressure over the mat. The process will produce treated effluent with low suspended solids and sludge at high solids consistency and can eliminate the need not only for a clarifier but also for sludge thickening and filtration units often used in pulp mills. Calcium chloride may be added to the effluent prior to primary settling or before filtration, to enhance the removal of suspended and total solids.

Abstract: The fueling station consists of a vacuum insulated storage vessel for storing a large quantity of LNG at low pressure. The LNG is delivered to one of two relatively small volume fuel conditioning tanks where the pressure and temperature of the LNG can be raised or lowered as dictated by the needs of the system. The pressure and temperature in the fuel conditioning tanks are raised by delivering high pressure natural gas vapor thereto from a high pressure bank. The temperature and pressure can be lowered by venting natural gas from the fuel conditioning tanks and/or delivering LNG thereto. The fuel conditioning tanks are connectable to a vehicle's fuel tank via a fill line to deliver natural gas and LNG to the vehicle and to vent natural gas from the vehicle to the fueling station.

Abstract: A beverage brewing apparatus which employs a water control assembly, a moisture recovery assembly, an improved thermostatic and low water sensor configuration and an easily removable sprayhead.  The control assembly controllably regulates the flow of water from the fill basin into the reservoir using a valve which is interconnected with a lid covering a fill opening in the hood portion.  Water from the basin will not flow into the reservoir, and thus will not produce a brewed beverage, until the lid is closed by the user.  The moisture recovery assembly employs a baffle opening and a collection portion on a vent to return condensation which may accumulate on the vent to the fill basin.  A sleeve is positioned in the fill water opening in the hood portion to collect condensation and to reduce the surface area of the water which may be affected by air movements through the brewing apparatus.  The thermostatic and low water sensing configurations position the temperature sensors outside of the water heating reservoir to prevent the accumulation of mineral and other deposits thereon.  A portion of the wall behind which the sensors are positioned is thinned in order to more accurately read the corresponding temperatures.

Abstract: Drugs are delivered in a sustained manner from an in vivo depot which is formed from a collagen-based injectable composition. The injectable composition is fluid when injected but undergoes crosslinking in situ to form a crosslinked collagen matrix which encloses the drug to be released. The composition also includes a flexible chain polymer which is similarly charged to the precrosslinked collagen. This flexible chain polymer is enclosed in the matrix as well when the matrix forms and alters the effective porosity of the matrix. The drug diffuses out of the matrix at a rate which depends upon the matrix's effective porosity.
