Title: Wave energy generator
Inventor: VOWLES ALAN KEITH
IPC: F03B13/18
Filed: 1992-02-10
Granted: 2000-06-20
Abstract: An apparatus and method for converting the motion of waves on a body of fluid into useable energy. The apparatus includes a floating or fixed rotatable support structure (5), a lever arms) (2) pivotally supported from the support structure and a wave follower(s) (1) fixed to one end of the lever arm(s) and positioned on the body of fluid. The lever arm is connected to an energy transfer device such as a piston rod (7) which drives a load in response to the action of waves on the wave follower. The wave follower is designed such that the upper portion (23) is constructed of a buoyant substance and the lower portion (24) constructed in the form of a hollow chamber (24a), open at the bottom (24b), with the seaward face (27a) being angled so as to harness the energy of the lateral force of the wave. The open bottom allows the chamber to fill with fluid on the rise of a wave. As the wave falls, suction, created by the closing of a valve (10) located in the upper portion, together with surface adhesion, restricts fluid from flowing out of the chamber, thus causing the wave follower to be pulled down by the weight of the fluid in the chamber. As the wave rises, hydraulic force is transmitted through the fluid in the open-bottomed chamber to the buoyant upper portion (23) causing the wave follower to rise. Extending seaward, vertical and inclined funnelling panels (4) will funnel the wave inward and upward toward the wave follower, thus amplifying the suave height.

Abstract: A sensor probe and sensor detection circuit used  in an electronic temperature control circuit for preventing the control circuit from driving an external device such as a heater when the sensor probe has been disconnected from the control circuit.  The sensor probe includes an NTC thermistor and a limiting resistor that are connected in parallel and potted in epoxy.  The thermistor and limiting resistor of the sensor probe form part of a lower leg of a voltage divider in the control circuit.  The sensor detection circuit compares the voltage signal generated by the sensor voltage divider to a predetermined threshold or ceiling voltage value.          During normal operation, when the sensor probe is attached to the control circuit, the resistance of the sensor probe insures that the voltage signal from the sensor voltage divider remains within a predetermined voltage range and does not exceed the predetermined ceiling voltage value.  When the sensor probe is disconnected from the control circuit, the resistance of the sensor voltage divider is decreased and the voltage signal exceeds the ceiling voltage value.  When the voltage signal exceeds the ceiling voltage value, the sensor detection circuit interrupts the normal operation of the control circuit and shuts down the heater.

Filed: 1993-02-03
Granted: 2011-04-26
Abstract: Polyester composition with improved impact properties, improved oxygen permeability and improved dimensional skrin-kage during heating. Impact modifiers are dissolved into a molten polyester to form a eutectic alloy. On slow cooling, the eutectic alloy of the invention freezes to form a mixture of particles of the impact modifier embedded in a matrix of the polyester. By con-trolling the solidification of the melt, the size and distribution of the precipitates from the melt can be controlled, which allows control of the mechanical properties. The precipitation can also be controlled either by homogenous nucleation or by heterogene-ous nucleation through the addition of a nucleating agent or the introduction of a suitable surface for nucleation. The invention also provides a process of manufacturing the above polyester, an article comprising this polyester and a process for making this article. The crystalline polyester article is useful as a container for microwavable, ovenable and/or frozen foods, and has im-proved gas barrier properties, impact strength, and post-mold dimensional stability between -60 °C and 200 °C.

Title: Method and apparatus for in-situ treatment of landfill waste and contaminated soil
Inventor: CIRCEO LOUIS J JR
IPC: B09C1/06
Filed: 1993-08-17
Granted: 2002-07-02
Abstract: A method is disclosed according to a first and second embodiment in which a plasma arc torch is used to vitrify and remediate a site containing municipal waste, contaminated soils, resulting from a hazardous material deposit or spill, or contaminated buried objects. The process steps of the first preferred embodiment involve drilling a series of holes into the waste material mass at proper spacing, inserting and operating a plasma arc torch in each drilled hole to pyrolize, remediate and vitrify the waste materials and allowing the melted materials to cool and harden. During the process, a gaseous by-product is produced and collected in a hood which is attached to scrubbing and chemical cleaning apparatus. The resultant gases are commercially useful as fuel gas and the vitrified residue is significantly smaller in volume than the original waste material volume, thus substantially extending the useful life of the landfill site and ultimately providing a firm foundation for construction.        The contaminated earthen material or subterranean deposit is pyrolyzed, melted or solidified by the plasma torch which is energized at the bottom of a cased, vertical borehole, and then gradually raised to the surface. An array of boreholes, appropriately spaced, will remediate an entire mass of contaminated material.       Similarly, buried objects such as metal drums containing contaminants and underground storage tanks may be selectively remediated at their specific buried depth.      Similar use is made of the plasma torch in a variation of this embodiment with the additional step of processing at selected underground locations in the borehole array to create a sealed horizontal layer, vertical cutoff walls or a sealed basin as a barrier against further leaching of contaminants into surrounding soil and groundwater.     Gaseous by-products of the pyrolysis process are collected, treated and processed, as appropriate.

Abstract: An automated interactive surveillance device provides passive infrared surveillance of a predetermined area to determine if an intruder enters the area. When the passive infrared detectors detect such an intruder, the device acts to aim a camera and ultrasonic rangefinder in the appropriate direction. The rangefinder determines the precise distance from the device to the intruder, whereupon the camera is accurately focused, the focal length adjusted for a relatively narrow field of view providing good resolution at the selected distance, and the angular elevation of the camera is adjusted appropriately. The passive infrared detectors may cooperate with a program to determine an approximate size for the detected intruder, based upon the amount of heat detected and the range determined by the ultrasonic rangefinder, to thus determine whether or not a human threat exists. The device may be elevated, with programming considering camera height, range to the intruder, and amount of heat detected to determine the approximate height of the intruder and aim the camera accordingly for a high resolution facial shot. One or more devices as needed may be connected to a remote monitoring site.

Abstract: A pipe and cable clamp is formed of a base part and a generally arcuately shaped receiving strap extending outwardly from the base part.  A joint is located in the receiving strap spaced from the free end and the joint is shaped so that the free end region extending from the joint can be folded into a receiving space bounded by the receiving strap.  As a result, pipes and cables of different diameters can be secured to the structural member, so that the free end region is folding into receiving space when smaller diameter pipes and cables are clamped, and the free end region is prevented from folding outwardly if larger diameter pipes are clamped, so that the free end region assists in securing the pipes and cable of larger diameter.
