Abstract: A horizontally moving belt has a waffle grid surface into the compartments of which dyes are injected in accordance with a desired color pattern to be printed. Carpeting is moved adjacent the waffle grid surface with the pile facing down toward the grid. A counter roller supports the waffle grid at the printing station, and an oppositely disposed protuberance-bearing pressure roller pushes the backing of the carpet so that the pile enters the compartments of the waffle grid and is immersed in the dye pattern. The protuberances ensure adequate immersion of the pile while permitting escape of air and avoiding squeezing of the dye from the pile, which would otherwise occur by engagement of the pressure roller with the grid walls in the absence of the protuberances. The angle of approach of the carpet to the printing station is slightly inclined from the horizontal to ensure a gradual depression of the pile and to avoid rolling the dye out away from the nip region of the printing station.

Abstract: Apparatus for permanently and protectively mounting "wet" thin sections of biological specimens on microscope slides, wherein each specimen is initially bathed in a low-volatile solvent containing a low concentration of first polymerizable material. Such solvent is allowed to evaporate, whereby the liquid polymerizable material permeates and protects the specimen. Following solvent evaporation, a second polymerizable material is layered over the specimen. Preferably, the first and second polymerizable materials comprise a mixture of low-volatility, low-viscosity, liquid acrylic reactomers and a U.V. light-sensitive catalyst system. A conventional cover slip or other planar transparent member can be positioned over the polymerizable materials, and the same are polymerized by exposure to U.V. radiation. The first and second now-polymerized materials encapsulate the specimen on the microscope slide, become integral and completely hardened and are fully devoid of any solvent.

Abstract: A system for tracking an endless image copying or recording belt and maintaining it in alignment within a confined area includes at least three rollers with four rollers being preferred. The first roller is a cylindrical drive roller and the second and third rollers are cylindrical driven rollers. The fourth roller is cylindrical along a major central portion and flares outwardly at the end portions. The third roller is mounted on support arms which, in turn, are mounted to pivot about the axis of the second roller and are biased normally to maintain uniform tension in the belt. If the belt creeps toward one end of the flared roller, the climb to the larger diameter displaces the tape which causes the corresponding end of the third roller to dip thereby causing the belt to move laterally back toward a central position.

Abstract: A moistening system for moistening the gummed flaps of envelopes being processed in a postage meter mailing machine includes a rotating endless belt extending into a liquid supply and transferring moisture to flaps pressed against it by a contoured finger positioned adjacent to the belt. The finger is curvedly bowed and twisted relative to the belt moistening surface so as to urge essentially only the gummed portion of the flap against the belt for moistening although a wide variety of envelope flap designs and sizes are processed. The endless belt may be pivotably supported to permit convenient removal of the liquid supply container.
