Title: Method for improving virus elimination efficiency and survival rate of hardening-seedling based on cucumber anther culture
Inventor: LIN CHENG
IPC: A01H4/00
Filed: 2021-10-20
Abstract: Disclosed is a method for improving virus elimination efficiency and survival rate of hardening-seedlings based on cucumber anther culture. The method includes steps of anther callus induction culture, callus differentiation culture, rooting culture of cluster buds, strong seedling culture of tissue cultured seedlings, hardening-seedlings, chromosome doubling, and transplanting, ploidy identification, and virus elimination efficiency detection by using molecular markers. A specific culture medium is used during tissue culture. The specific culture medium is a culture medium prepared by replacing sucrose with trehalose and supplementing nutrients such as a filtrate of black goji berry juice based on a conventional culture medium formula. After culture, virus elimination is identified by a molecular marker technique. The present disclosure significantly improves the virus elimination efficiency, and is characterized by easy operation, low cost, high survival rate after transplanting anther cultured seedlings, strong resistance, easy promotion, direct use in production, and excellent economic and social benefits.

Title: Photosensitive plate for an electrostatic image - has photoconducting material in layers of differing particle size and sensitivity
IPC: G03G15/08
Filed: 1977-05-06
Abstract: To form an electrostatic image by electrophotography, an original image is illuminated and at the same time an alternating current corona discharge is laid onto the primary charged translucent insulating layer of a photosensitive plate. This gives an electrostatic image on the layer, in accordance with the difference in the surface potential, brought about by the light and shade pattern of the original. The insulating layer is on a photoconductive layer which in its turn is supported by a substrate, and the photoconductive layer is itself formed by a number of layers of photoconductive particles of differing dimensions. The translucent insulating layer may be on a photoconductive layer on the other side of which there is a conducting substrate. The substrate on the face of the photoconductive layer turned away from the translucent insulating layer, may itself be of insulating material. Problems associated with reproduction in which fatigue of the photosensitive material reduces the quality of the image so that it cannot be used for a number of times over a long period, and in which translucent layers have to be so thin that breakdown occurs easily, whilst the layer wears quickly and cannot be protected adequately, as obviated.

Title: Ship navigation micro-map appts. - has map holder and projector for directing section of map on instruction screen
IPC: G01C21/22
Filed: 1981-03-23
Abstract: The apparatus includes two independently-movable carriages in the form of transparent plates which are able to be displaced to and fro along the X,Y axes, respectively. On top of the plate a map holder is disposed which receives a micromap insert. A main projector produces an image of a section of the map onto a display screen. Additional working projectors are provided spaced respectively along X,Y axes from a prism mirror in the optical path of the beam from the main projector to the display screen. The marking projectors provide, via plane mirror, respective cross-marked lines on the display screen, each one of the respective divisions representing a nautical mile. The optical line is used to indicate the estimated course relative to the projected image of the map section. The cross marking then represents the position of the last-taken observation. The map section image is caused to move relative to the optical line by manipulation of wheels to provide X,Y displacement of the plates. In a second embodiment movement of a marking projector is caused by pulses from the ship's compass and movement of the map holder is derived from the ship's log and compass via a computer.

Abstract: Polyurethane resins are described having high impact strength and other structural strength properties, and significantly improved resistance to deformation by heat. The properties of these materials are such as to make them comparable to engineering thermoplastics such as nylon and like materials commonly used to fabricate structural components such as automotive parts, equipment housing, sporting goods, furniture, toys, household and like consumer goods. The resins are prepared from organic polyisocyanates, an isocyanate-reactive material (polyol, polyamine, etc.) having an average functionality of at least 1.9, a Tg less than 20 DEG  C. and molecular weight of 500-20,000, and one or more low molecular weight extenders the major distinguishing feature being the markedly lower proportion by weight (2 to 25 percent) in which the isocyanate-reactive material is employed as compared with polyurethane resins conventionally prepared in the art. Depending upon the particular combination of reactants employed the polyurethanes of the invention can be thermoplastic or thermoset and can be prepared in both cellular and non-cellular form.
