Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.

Abstract: The images produced by conventional scanning electron microscopes, in which a goniometer arrangement serves as a specimen support, are subject to losses of resolution in the case of large, heavy specimens. These losses are traceable to vibrations of the ground which induce vibrations in the spring/mass system formed by the goniometer on the one hand and the specimen on the other hand. These vibrations are produced relative to the electron beam of the optoelectronic system and the specimen. To eliminate these losses of resolution, the goniometer is designed as a mounting for the optoelectronic system and the detectors, while the specimen support is designed as a rigid, stationary specimen stage. The resonance frequencies of the spring/mass system are thereby shifted into a range in which no excitation due to ground vibrations can occur. In addition, the mobility of the optoelectronic system and of the detectors permits greater mobility inside the specimen chamber.

Abstract: The present invention relates to aqueous compositions of substances, such as organic molecules, which are useful to protect and preserve viable plant or animal cell membrane and tissue exposed to hypothermal and hyperthermal temperatures or nonphysiological chemical conditions, and to modify the freezing process of liquids in biological plant or animal cells or tissue. More specifically, the present invention relates to the use of antifreeze polypeptide or antifreeze glycopeptide which is derived, for example, from the fluid or serum of Artic and Antarctic fish. Preferred antifreeze compounds are related to those polypeptides having multiple alanine-alanine-threonine- or alanine-alanine-alanine- segments. In some embodiments, a pendant sugar group is covalently attached to each threonine moiety. An aqueous solution of the peptide or glycopeptide is contacted with cells ova, sperm, oocytes, embryos, tissue, an organ, or a whole living plant or animal. The cells, tissue, organ or plant or animal is then carefully cooled and/or frozen at 0 C or below (in some cases to -196 C or to 4 K) and held at the low freezing (or vitrification) temperatures. The ice forms, if at all primarily along the c-axis with the result that cell membranes are not disrupted and the cells are not dehydrated. The cells, tissue, whole plant or organ or animal are carefully thawed, and all are found to be viable. The preserved organs are particularly useful transplant organs for a human being.

These control signals represent at the same time the value of the relative angular displacement of the head with respect to the reference mark while travelling along the track. A space-stabillized gyroplatform on the measurement platform detects the absolute change in position of the measurement platform which is used to correct the angular displacement values of the displacement head. The distance covered is detected by a separate distance measuring device or by the gyroplatform. The actual position with respect to the reference mark derived from this data is compared to the set value in a track survey plan and if necessary the track is corrected on the basis of said values.
