Title: Gasification of low calorific value solid fuels to produce electric energy
Inventor: VALKANAS GEORGE N
IPC: F01K23/06
Filed: 1994-06-03
Abstract: An original method for utilization of solid fuels of low calorific value in the production of electrical energy is described which leads to 3 times higher yields than these obtained today by burning in an operation working with efficient complete internal pollution control. The method covers solid fuels of low calorific values 800 to 3.000 Kcal/Kg which pyrolyse by 30 % to 80 % at temperatures under 600 °C which are utilized in an operation consisting of two pressure reactors in series the first of fluidized bed type where the pyrolysis is perfomed at 450-600 °C which is a reductive process forming hydrogen sulfide and a second pressure reactor of solid bed type where the carbon residue of pyrolysis is directed to be gasified with oxygen or with oxygen-steam where the sulfur is oxidized to sulfur dioxide. The two gas steams are mixed under conditions to neutralize the contained sulfur gases by a Claus reaction: 2H2S + SO2 ? 3S + 2H2O. The fuel gases are produced at temperatures of 600-800 °C and at pressures of 20 to 30 atm and are utilized in an external turbine to produce electricity from the thermomechanical energy contained or are exchanged to produce pressure steam. Then the fuel gases are used in a combined circle arrangement to produce electric energy by utilizing their thermal values.

Patent CA-2155035-A1 (CA)
Inventor: NENNIGER JOHN
IPC: E21B43/24
Filed: 1991-09-25
Abstract: This invention describes a method of stimulating production from an oil well by removing solid wax deposits from a production zone. An electrical resistance heater comprised of a packed bed of spherical heating elements is lowered through the tubing on a wireline and placed adjacent to the perforations. Solvent is pumped through the heater to raise its temperature by 200°C and then into the formation to contact wax deposits. The solid wax deposits are liquified and together with the oil and the solvent form a single liquid phase. The wax is then removed from the formation by placing the well back on production. Because the invention completely avoids the use of either water or gas, the saturation of the water and gas phases in the formation is minimized, thereby maximizing the mobility of the liquid phase containing the wax and facilitating the removal of the liquified wax from the treatment area before it reprecipitates.  The packed bed heater has a large surface area and a large heat transfer coefficient, so high power rates (150 kW) can be achieved within a compact volume (6m long x 5cm id) without solvent degradation.By heating the solvent to a high temperature, a minimum volume of solvent is required, thereby minimizing production downtime and solvent costs. The burnout and catastrophic failure problem usually associated with resistive heaters is avoided due to the multiplicity of current paths through the packed bed.

Abstract: A physical presentation of an objet(ll2, 132, 134, 122) is changed in a system with an object oriented environment (200, 240). The system includes a display (300) for present-ing physical manifestations of ob-jects (374, 378, 330). The system (200, 240) has a first target object (374, 378, 330) containing a first presentation method (222) having a universal interface protocol (264). The first presentation method (222)                               presents a first physical manifestation on the display. This universal proto-col (264) allows the first presentation method to be accessible by other ob-jects capable of communicating us-ing the universal protocol (264, 262). The system (200, 240) also contains a costume object (262) which enables communication with the first target object (272, 274, 266, 268) - e.g., the costume causes the target object to display itself at the costume object's position of the screen (382, 384), in effect displaying the costume object (262) wearing the costume of the tar-get object (272, 274). If the user de-sires that the costume object (262) presents another physical manifesta-tion, the user associates it with another target object (272, 274), which the costume object (262) may also cause to present this other physical manifestation (382, 384, 286) on the display (300).

Title: Two-dimensional sensor using laps for measuring cell activity
Inventor: SUGIHARA HIROKAZU
IPC: G01N33/487
Filed: 1996-06-19
Abstract: A two-dimensional sensor is described including a substrate having a Si layer, a SiO2 layer and a Si3N4 layer. On the surface of the Si back side, a thin film is formed by vapor deposition for making an effect electrode. On the surface of the Si3N4 front side, a fence is attached for containing a sample cell, culture medium and a reference electrode. This sensor is placed in an incubator and a bias voltage is applied between the effect and reference electrodes.          When a high frequency modulated laser beam irradiates a spot of the back side of the sensor substrate, a signal of AC photocurrent is obtained from the effect electrode. This signal corresponds to a potential alteration due to the cell activity substantially at the spot. The signal is processed in a computer. Therefore, the beam spot size and location, corresponding to the size and the location of the measurement electrode, can be adjusted easily by focusing or moving the laser beam.
