Title: Apparatus and method for drying printed material by means of infrared radiation
Inventor: VROOME CLEMENS JOHANNES MARIA
IPC: B41F23/04
Filed: 1994-01-19
Abstract: The invention relates to a method for drying printed substrate material (base material), wherein heat for the drying is transmitted to the substrate material at least in part by means of IR radiation, the IR radiation being generated by at least one radiating body being heated by means of hot gases to a temperature at which the radiating body emits IR radiation. Preferably, the webs of substrate material to be dried are initially dried by IR radiation and then dried by hot gases. This leads to a considerable reduction in the energy required. According to another preferred embodiment, hot gases which have passed the radiating body are used, at least in part, to dry the substrate material.

Title: Super-non-wettable carbon black as a functional activator of human spermatozoa
Inventor: ESMERYAN KAREKIN
IPC: C12N5/00
Filed: 2021-11-30
Abstract: The present invention relates to a method for the activation of human spermatozoa which would be applied in the area of reproductive medicine and more particularly in technologies intended to improve the functional status of male gametes prior to medical interventions related to assisted reproduction. According to the proposed method for the activation of human spermatozoa, super-non-wettable carbon black nanoparticles in powder form, obtained by synthesis of rapeseed oil flame under controlled combustion conditions, are placed in freshly excreted human ejaculate and the resulting suspension is incubated for a period of 90–270 minutes at a temperature of T = 37 degrees Celsius, relative humidity 98 % and CO2 content ~5 %. The method is beneficial in that the observed cytotoxic effect against male gametes is either is very limited (not more than 20 % impairment of cell motility) and/or non-existent. Moreover, carbon black particles do not penetrate live spermatozoa and do not adhere to their surface, meaning that the activation is achieved through electrostatic and/or biochemical interactions with the seminal plasma. Last but not least, the carbon black synthesis process is fast and cost-effective, and provides the possibility of additional functionalization of the material with different nanoparticles. The human spermatozoa activation method would be widely applied in the area of reproductive medicine for diagnosis, selection and subsequent improvement of the functional status of live spermatozoa in cases requiring intracytoplasmic injection of human gametes as well as in classical in-vitro and/or intrauterine insemination procedures for the purposes of assisted reproduction.

Abstract: 按照本发明的一个装置，包括一个支承结构(12)，具有一个主要部分(14)，带有第一和第二支臂部分(24，26)成形在它的上面，用于彼此相对地移动，以及一个辅助部分(28，32)，带有一个夹紧部分(30，34)或者活门部分，整体地成形在每个支臂部分的一个外末端上，用于与其一起移动。一个主要致动器(16)，工作上与主要支承结构相配合，在响应主致动器的一个电激励时，驱动支臂部分彼此相对地移动。辅助致动器(46，52)工作上与辅助部分相配合，用于在响应每个辅助致动器的一个电激励时，独立地驱动辅助部分在一个开启位置和一个关闭位置之间移动。每个致动器可以彼此独立地工作。装置可以工作以提供一个两方向的电动机，一个两方向的泵或一个两方向的压缩机，它取决于主要和辅助致动器的触发的选择的形状和顺序模式。
