Title: Method for identifying species of aedes based on pcr-ms
Inventor: XIAOMEI CAO
IPC: C12Q1/6888
Filed: 2020-06-17
Abstract: Disclosed herein is a method for identifying the species of Aedes based on PCR-MS, 5 including: establishing gene databases (COI, COII, 28s and Cth400) for the identification of the species of Aedes; establishing Aedes DNA two-dimensional codes; designing a primer for multiplex PCR-MS; and performing multiplex PCR-MS analysis. SNP sites specific to respective species of Aedes mosquitoes are obtained by analyzing thousands of sequences from nine species of Aedes mosquitoes. Two or more gene-specific SNP sites are selected for each 10 species, and the specific and non-specific sites of other species are used as exclusive references to design an analysis system, in which the species of an Aedes specimen can be determined through the base recognition at multiple sites, improving the identification accuracy for the species of Aedes and effectively avoiding the missing detection.

IPC: G03G17/04
Filed: 1975-11-24
Abstract: Photo-electrophoretic image formation is effected with an image layer consisting of a suspension of electrically light sensitive pigments (I) placed between a conducting electrode and a blocking electrode. The conducting electrode is at least partly transparent for electromagnetic radiation towards which at least a part of the pigments is sensitive, and the blocking electrode is coated with a material (II) that injects charges in the dark, this material being dispersed in an electrically insulatings adhesive org. material (III) as binder.

Title: Anchorage esp. for offshore platform - consists of piles through guides with chamber giving access for welder
IPC: E02B17/02
Filed: 1976-12-24
Abstract: The foot of an offshore structure is anchored to the seabed by driving one or more piles through a guiding element attached to the foot structure; the pile or piles being then welded in place, or secured by another suitable method. The guiding element has the form of the driven pile with a chamber taking up a relatively large intermediate space. This is provided with an access for a mechanic, and above and below it joins two relatively short guide tube stubs. When the pile has been driven into the seabed, the circular space between the pile and the guide tube stubs is sealed; the chamber being then pumped dry. An operative can then enter the chamber to make the fastening between the pile and the guide. The piles are hollow and an inner pipe section with a smaller dia. than the internal diameter of the pile is inserted into the pile at a point where it will be aligned to the working chamber of the guide. At the top and bottom ends of the inner pipe section between it and the inner wall of the pile a seal is fitted, and this space is also pumped dry to ensure good welds. Method is a much cheaper and more reliable method of anchoring than is obtained by pumping special concrete between guide element and pile.

IPC: F02G5/02
Filed: 1980-03-12
Abstract: System for waste heat recovery, comprising a combustion machine (2,3) with a compressor (4) for the combustion air (30) and means (7) like a heat exchanger (13) and/or a recirculation duct (14), to transfer heat, contained in the combustion gases (37,38,39) after their expansion in the machine (3), to the combustion air flow (33) before its entry into the compressor (4).

Title: Delay detonator
Inventor: YUNAN MALAK ELIAS
IPC: F42B3/16
Filed: 1982-04-26
Abstract: improved uniformity of timing, and particularly reduced sensitivity of timing to minor variations in delay charge size, are achieved in delay detonators by placing a loose load of a flame-sensitive ignition composition between a pressed delay charge and an ignition assembly, e.g., a percussion primer, at the actuation end of the detonator. The loose ignition charge has a free surface and is adapted to be ignited in response to direct contact with flame emitted from the ignition of a charge in the ignition assembly. Preferably, the delay charge is pressed into a plastic carrier which, in a non-electric detonator, has an open end terminating between the walls of the detonator shell and a primer shell that closes the actuation end of the detonator, and the ignition charge is loosely loaded into a metal capsule seated against the delay charge.
