(n.) The part of a printing press which presses the paper against the type and by which the impression is made.
(n.) Hence, an analogous part of a typewriter, on which the paper rests to receive an impression.

Example Sentences:
(1) The incidence of damage immediately after freeze-drying was greater for cells dried at the higher platen temperature and was influenced by the composition of the menstruum in which the cells were dried.
(2) These modifications involve the use of a radiused edge on the dimpling tool, a rubber O-ring on the polishing tool, and not rotating the sample platen during polishing.
(3) The material was cured in certain thicknesses in the heat platen press and by boiling without porosity.
(4) This dependency on cross-sectional area is probably due to friction-induced stress inhomogeneity at the platen-specimen interface.
(5) Salmonella typhimurium survived freeze-drying at a platen temperature of 120 F (48.9 C) and also, though to a much lesser degree, at 160 F (82.6 C).
(6) The coupling DC amplifier provides a DC offset voltage at all gain settings of the pantograph which is sufficient to reposition the pen of the X-Y plotter in the center of the plotter's platen, regardless of the location of the specimen on the microscope slide.
(7) A finite element analysis is used to study a previously unresolved issue of the effects of platen-specimen friction on the response of the unconfined compression test; effects of platen permeability are also determined.
(8) This enhancement of material properties at the highest strain rate was due primarily to the restricted viscous flow of marrow through the platen rather than the flow through the pores of the trabecular bone.
(9) Trousers-shaped specimens were prepared between two platens.
(10) An increase in trabecular orientation toward the loaded platens was observed, and a statistically significant decrease in connectivity was documented.
(11) This model utilized an implantable hydraulic device incorporating five loading cylinders and platens in direct contact with an exposed plane of trabecular bone.
(12) After freeze-drying for 8 hr at a platen temperature of 49 C and rehydration with a mineral salts medium, survival of the cells was 0.6%.
(13) The value of the heat platen press as a time-saving device and its applications in a maxillofacial laboratory were discussed.
(14) Control thicknesses of impression material were first formed between the measuring platens of a micrometer, and light transmission values (relative reflections) were measured through these control thicknesses of impression material held against air-abraded, noncast gold alloy.
(15) According to Drouzy, the key inspiration for Gertrud, based on a play by Hjalmar Söderberg, was Dreyer's discovery at 73 that Maria von Platen, Gertrud's real-life counterpart, spent the last years of her life in a house only 10 miles from the site of his own conception.
(16) A porous platen above the specimens allowed the escape of marrow during testing.
(17) In a second experimental condition, a platen-fixed LED matrix fixation target was illuminated 0.91 m vertically above the subject.
(18) An investigation was designed and carried out to compare methyl acrylic resin processed by three methods--boiling, in the heat platen press, and a 9 hour, 75 degrees C cure.
(19) The modifications to the dimpling and polishing tools allow more control of the geometry of the dimple, while not rotating the sample platen allows a thinner sample to be produced and permits the use of the sample translation micrometers to shift the location of the thinned area during polishing.
