Title: Control method for electricity-saving of printing system
Inventor: KIN KEIRETSU
IPC: B41J29/38
Filed: 1995-01-04
Abstract: PURPOSE: To provide a method for controlling power saving in printing system by which a picture printing device can start printing operations from a power saving mode in a shorter time and the speed of response to print of the device can be made faster. CONSTITUTION: In a method for controlling power saving in a printing system which is constituted of a computer having an input means and a picture printing device which performs printing operations in response of a print code supplied from the computer so that the system can be set in a power saving mode when the system does not perform printing operations for a fixed period of time, a specific input is set to the input means of the computer and, when the specific input is generated during the power saving mode, a computer outputs a dummy print code (DUMMY PRINT CODE) to the picture printing device and the printing device senses the code (step 103) and is set to a standby state after executing make-up operations.  When this method is used, the time required for waking up the picture printing device can be shortened in starting printing operations from the power saving mode, because the computer causes the printing device to perform the wake-up operations before an actual print code is inputted.

Patent DK-43492-A (DK)
Inventor: CALDERHEAD DAVID
IPC: G01N33/558
Filed: 1992-03-31
Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.

Title: Oil recovery by an in situ combustion
IPC: E21B43/243
Filed: 1982-09-15
Granted: 1991-06-30
Abstract: Enhanced recovery of oil from subterranean sedimentary formations by an in-situ combustion method employing a pattern of an injection well and several production wells, spaced-apart by a treatment zone. Combustion is controlled by placing at least one fluid conduit in a treatment zone and introducing a control fluid through it to modify the flame front. Oxygen may be introduced to take over from combustion air initially introduced through the injection well, to sustain combustion and advance the flame front. Water may be injected through the injection well, alternating with the oxygen through the control conduit to continue a wet combustion method started with air. The strategic placing of control conduits and the introduction of appropriate fluids may be employed to improve the sweep geometry by advancing the flame front or retarding it, or invading areas behind it. Safety means is provided for introducing the oxygen at a velocity greater than the maximum flame velocity encountered in the flame front.

Title: An improved process for the purification of organic liquids
IPC: B01D3/36
Filed: 1945-01-02
Abstract: <PICT:0587704/III/1> The process of the parent Specification is modified to enable organic liquids soluble in water, e.g., lower alcohols and ketones to be recovered continuously instead of batchwise by the provision of successive distillation columns 50, 60. The crude liquid is introduced through line 51 into distillation column 50 which is supplied at the base with live steam.  Low boiling impurities, together with steam and some of the material to be recovered, are removed overhead as vapours, which are condensed in condenser 53 and separated into two liquid layers in decanter 54. The upper layer is partly returned as reflux to column 50 and the remainder sent to mixer 72.  The lower aqueous layer is withdrawn through line 57 and added to the crude liquid supply.  The liquid from the base of column 50 is passed through line 61 to column 60 which is supplied at the base with live steam.  The material to be recovered is withdrawn, as vapour, overhead, condensed in condenser 63, and passed to drum 64; part of the condensate is returned as reflux to column 60 and the remainder is withdrawn to storage as product.  The high boiling impurities are withdrawn throngh line 67 to decanter 68 from which the upper non-aqueous layer is removed through line 71 and sent to mixer 72 where mixing with the low boiling impurities from column 50 takes place.  The mixture is introduced into wash tower 70 where it is countercurrently contacted with water, the aqueous extract so obtained being added to the crude liquid supply through line 75. A modification is described in which column 60 is heated by means of closed steam.
