Abstract: An anemometer includes a tubular cylindrical housing having an outer sensing end portion with a sensing passageway formed by opposite parallel flat walls integrally formed with the tubular cylindrical housing. A rod-like sensor is mounted centrally between the flat walls and adjacent the upstream opening to the passageway. An ambient temperature element sensor and a compensator, each in the form of a flat chip, are adhesively bonded by a flexible adhesive to the inner wall surface of immediately adjacent the passageway. In the forming method, a tubular cylindrical member of hardened stainless steel has diametric openings formed in an outer sensing end. A press is coupled to the opposite curved walls of the passageway and the walls flattened to form the integral, parallel flat walls.

Abstract: A reader/printer apparatus includes a main frame having an optical system for exposure of photocopy paper with the image on a film carrier in combination with an integrated modular developing station which is adapted to receive any one of a plurality of different developer modules. Each module is a self-contained plug-in type structure and includes a dry silver paper developer module and an electrostatic developer module are provided. Each module includes an infeed unit and a discharge unit for passing the paper from the exposure unit through the developer module. The dry silver module includes a suitable transfer roll and mating heating bars for developing the exposed dry silver paper. The electrostatic module includes a magnetic toner brush assembly to deposit toner particles in the image area. Each module includes an essentially identical rectangular frame structure corresponding to a rectangular developer chamber having a suitable guide means.

Abstract: A film reader includes individual drive systems for driving a storage reel to rewind a film strip and a take-up reel to unwind the film strip by pulling the film strip from the opposite reel. Each drive system is the same and includes a fast drive motor and a slow drive motor. A speed reduction pulley train has a first stage and a second stage connected in series with a first stage output pulley in drive coupling to an input pulley of the second stage by a one-way clutch. A slow speed motor is connected to the first stage. A one-way clutch connects a high speed motor in drive coupling to the opposite side of the input pulley. The output shaft is connected to the pulley train by a spring output clutch having a pulsed release control to disconnect the output shaft from the pulley train and permit free rotation thereof.

Abstract: A compact thermal developer is mounted in a microfiche reader printer. The developer is a two-stage unit having a pair of roller-heater units located to pass on exposed copy sheet in one direction through succeeding stages in an over-and-under movement to develop the copy and produce a flat hard copy. Each roller-heater unit includes a roller having an outer thin friction coating rotatably supported within an arcuate recess portion of a heater bar. The heater bar and roller are arranged with roller biased toward the heater to grasp the copy sheet. The roller includes a thin aluminum tube supported by heat insulating end members mounted on a shaft with a floating connection to support the tube with a permission relative axial movement to compensate for different coefficients of thermal expansion. A thin silicone rubber coating on the tube establishes positive sheet movement while providing sufficient thermal transmission to present a thermally light background member.

Abstract: A temperature sensor is fixedly attached to a thin, flexible disc-like metal plate with sufficient flexibility to conform to the general shape of a surface. The sensor may be thermocouple, a resistor, a semiconductor or other structure. This thin metal member has a low thermal capacity or mass and a relatively high degree of thermal conductance. A tubular insulating and elastic member is fixedly attached to the periphery of the plate and to a tubular housing having an attached handle. The housing functions as a support and an enclosure for the temperature sensitive unit, flexible connecting leads and the like. The elastic member permits the plate to pivot about the housing to move into complete surface engagement with the surface being monitored. The electrical wires connected to the temperature sensitive unit are relatively fine to minimize the thermal mass and capacity added to the unit. The wires are also flexible such that they do not interfere with movement of the plate.
