Patent NL-2029084-A (NL)
Title: Electrical capacitance tomography sensor calibration method
Inventor: JIUWEN BAO
IPC: G01N27/22
Filed: 2021-08-31
Abstract: The present disclosure belongs to a technical field of monitoring of durability of concrete, and relates to an electrical capacitance tomography sensor calibration method. A process of the method includes five steps of preparation of concrete sample, equipment connection, preparation work, measurement of capacitance values and normalization. Two same ECT sensors are used to implement off—line calibration and on—line measurement; and the calibrated concrete samples are placed inside the ECT sensor for on—line calibration to visually monitor unsaturated moisture transmission inside the concrete samples. Compared with direct moisture calibration, the calibration of concrete samples with different saturation prepared through a blast drying oven, can more realistically simulate the moisture inside the concrete samples in a real environment; the calibration process is simple and fast, and can correct the normalized capacitance values in time, thereby improving the accuracy of ECT imaging, achieving accurate calibration of visual monitoring of unsaturated moisture transmission in a cement—based material, and overcoming the shortcoming that a conventional calibration method is not suitable for a monitoring process of liquid—solid two—phase flow of a cement—based material.

Title: Method for Determining Purity of Nicotine by Use of GCMS-GC Method
Inventor: JIE LONG
IPC: G01N30/72
Filed: 2022-07-22
Abstract: The present invention discloses a method for determining a purity of nicotine by use of a GCMS-GC (gas chromatography mass spectrometry-gas chromatography) method, 5 including: Step A: preliminarily determining a purity (nic%) of the nicotine by use of a GC/MS method; Step B: determining a moisture content (wat%) of the nicotine by use of a GC method; and Step C: carrying out correction to obtain an exact purity (nic%) of the nicotine, wherein a correction formula is expressed as NIC% = nic%*(100% - wat%). The present invention establishes a method for determining a purity of nicotine 10 by use of a gas chromatography mass spectrometry combined with a gas chromatography. Compared with a gravimetric method using a tungstosilicic acid widely used at present, because in this method, after a modern chromatographic technique is utilized to efﬁciently separate a sample, the molecular weight (one of inherent physicochemical constants) of nicotine is taken as a detection target, the method 15 is high in speciﬁcity for nicotine detection and uneasy to be interfered by other impurities, especially alkaline impurities (alkaloids, inorganic bases) in the sample, and accordingly, when being provided for carrying out purity detection on nicotine samples, especially those samples laid long and with high impurity contents, the method is easy to operate, has a strong separation capacity and produces reliable qualitative and 20 quantitative results. Thus, the method may be promoted as a rapid detection method for nicotine purity.

Title: Rolling device for machining drills
IPC: B21H3/00
Filed: 1969-04-18
Abstract: The feed guide is a non-metallic bush which corresponds to the bar dimensions and is arranged within the induction heater near to the devide for feeding the bars at regular intervals. The removal guide is a bush with a conical bore which corresponds to the shape of the workpiece shaft. This bush is movably mounted to move around and along the centre line of the roll device. Rectilinear movement is performed between the non-operative rolling rolls through to the feed guide so as to receive a bar to be machined direct from the feed device, and to centre the conical shaft of the bar in the bore provided. The part of the workpiece to be machined is heated in the introduction heater. This is followed by the removal guide, and the heated bar performing a helical movement in the reverse direction, during which the rolling rolls become operative and roll the helical thread on the bar.
